Mayor Bailey called the meeting to order at 7:00 p.m. 2. PLEDGE OF ALLEGIANCE The audience, staff, and City Council Members stood and recited the Pledge of Allegiance. 3.

OPEN FORUM Mayor Bailey opened the Open Forum. John McLoone, publisher of the Cottage Grove Journal, 1304 Vermillion Street, Hastings, addressed Item F on tonight’s agenda, to designate the St. Paul Pioneer Press as the City of Cottage Grove’s newspaper for official publication in 2024. He’s hopeful that they’ll reconsider a rubber stamp of staff recommendation. We started our newspaper during the pandemic in 2020; it’s a lot of work, but we’re dedicated to helping the community any way we can. We work hard to be a good corporate citizen, we donate to and promote local causes. We’re an active member of the Cottage Grove City Council Meeting Minutes January 3, 2024 Page 2 Area Chamber of Commerce. We had so much fun at the Cottage Grove Community Showcase the last few years, as countless people stopped by our booth and thanked us for bringing a newspaper back to Cottage Grove. His wife was actually shocked; she said, people like you. We can’t do it alone, though, we’re nothing without the community. We publish weekly. For generations, the City of Cottage Grove recognized the importance of its weekly newspaper, bestowing it as its official newspaper. This city was built on items that had to be posted in a weekly newspaper, and looking around the community, he’d say that didn’t pose too many problems or obstacles. All the permitting got done, everything got built, and this town is thriving. The intent of the statutes governing public notices isn’t convenience; they’re meant to notify the public in the place they’d be most likely to see them, that undoubtedly is the Cottage Grove Journal. Unlike many newspapers, we’re on a steady growth trajectory, and he will admit this would certainly be as much of a shot in the arm for us to be designated as the official newspaper as it is a kick in the backside every year to see these notices go to St. Paul. We work hard to serve our communities. We take public notices very seriously, we bend over backwards to help our municipal partners. Deadline for public notices, honestly, is when his paper goes on the press. We remade plates in our Hastings paper last week because something came in two hours after we were supposed to actually be on press, but because of the holiday we were able to make the change and get their notice in. The City of Cottage Grove is honestly the only municipality he can think of that doesn’t designate the local newspaper as its newspaper of record. Can we change that tonight? Please give us a try. As your City Attorney will tell you, if it doesn’t work out, you can make a change back at any time during the year; this isn’t a one-time thing. He admitted they don’t have an average circulation of 30,000 readers in Ramsey, Dakota, Washington, Anoka Counties and western Wisconsin every day. To him, that doesn’t matter. We target Cottage Grove and we’re proud of that. Thank you for your time. Mayor Bailey thanked Mr. McLoone and asked City Attorney Kori Land if she wished to comment on this. Attorney Land stated the memo that’s in the Council packet explaining the legal qualifications for your official newspaper are outlined pretty well. Given that you don’t have a local newspaper that is in the City of Cottage Grove that has an address here, you’re able to choose your official newspaper as one that is within an adjacent county. So, you could choose the Dakota County Cottage Grove Journal because their address is in Hastings, but you could also choose the St. Paul Pioneer Press. From a legal standpoint, they’re equal. It then becomes a practical standpoint, the advantages that one or the other has; so, that’s what the Council has to weigh. As no one else wished to address the Council, Mayor Bailey closed the Open Forum. 5. ADOPTION OF AGENDA Mayor Bailey stated he wanted to make a quick correction on one of the items on the agenda. One of the items we were looking at doing tonight was Item 13A, Workshop, City Council Meeting Minutes January 3, 2024 Page 3 Open to the Public, which is a workshop to discuss the Viewpoint Project. That has been removed from our agenda this evening for a future meeting date.

Approve the December 6, 2023 City Council Regular Meeting Minutes. B. Approve the December 20, 2023 City Council Regular Meeting Minutes. C.

COUNCIL COMMENTS AND REQUESTS Council Member Khambata wished everyone a Happy New Year. He hoped everyone had a safe holiday. We had a Swearing In Ceremony earlier this evening, so, he congratulated all of our Public Safety members who were either promoted or retired, in Gunnar’s case. Council Member Olsen stated he hoped everyone had a wonderful holiday. He was, unfortunately, not able to be present for the meeting right before Christmas. He knows that it wasn’t a very long meeting, but he apologized as he was traveling for work. His understanding is that things went well. First of all, he wanted to say thank you to all of the staff for the hard work that they put forth in 2023. As we transition into 2024, he knows that hard work is going to continue. Part of that is all of the various activities that took place over the holiday break; he believed we had several hockey tournaments in town, so Ice Arena and Park and Rec staff were definitely busy. We haven’t had a lot of snow, but we had some slick spots, so he believes our Public Works team was out salting roads, etc. It never fails, that always happens during the holiday season. We’re very grateful that all of those folks were so committed to come out and do the work that needed to be done, even during the busy holiday season. Council Member Olsen mentioned that the month of January is Firefighter Cancer Awareness Month. Incidents of cancer and very specific types of cancer are much more prevalent in firefighters than in the general public; hence, the reason that we have a Firefighter Cancer Awareness Month. One of the things that stands out about that to him is we actually have a retired firefighter who’s battling cancer; it’s difficult to tell what in particular may have caused that. There’s a lot of research out there about some of the different chemicals that get used in fighting fires and the firefighting foam, etc. So, if you know any firefighters in your life, make sure that you give them an extra special thanks this month for putting themselves on the line in several different ways to help protect our communities. We had the opportunity this evening to see the badge-pinning ceremony for our new Fire Chief, Jon Pritchard, which was fantastic, along with our new Captain in the Public Safety Department, Brad Petersen. We also have three new sergeants (one of whom is pretty familiar to at least somebody on this Council): Sergeant Nick Bailey, Sergeant Dan Schoen, and Sergeant Pat Young. All three of them got their badges tonight, and it was a really special time. That’s something as a City Council that we take a lot of pride in, because those folks all were kind of homegrown, they grew up in our department, so, that was very fun. Council Member Olsen mentioned of course in the month of January, a lot of laws change. So, if you haven’t paid any attention, there’s a lot of different legal information that’s out there about some of the laws that our legislature passed in 2023 that have now taken effect in 2024. Some of those are paid leave for employees at different City Council Meeting Minutes January 3, 2024 Page 5 businesses, there was also a minimum wage increase, etc., so avail yourself of that information. A lot of that comes out through the State of Minnesota, through their various websites, social media, Twitter, etc. There are probably some things that apply to you, so if you’re not familiar with all the different legal elements that took place in 2023 that have now become official in 2024, take a few minutes and inform yourself. He thinks that would be to your benefit, a lot of good stuff happened last year at the Capitol, and we’re really excited to see more good stuff this year. Council Member Thiede said Happy New Year, he’s looking forward to a great 2024. He also congratulated the Public Safety recipients tonight, they did a good job. He also said that things are definitely starting to pick up with Strawberry Fest for 2024; it’s actually going to be on the third weekend in June this year, the weekend after Father’s Day. Make sure to take note of that, and we definitely can use the help. Our first meeting this year will be on Monday night at 6:00 p.m., here in the St. Croix Room, and we’d love to get people to come in and help. We also have meetings on the third Monday of the month, so go to the website to find the location; sometimes they’re here, sometimes at Carbone’s. We’d love to have people come out and help, we definitely need the help. Council Member Garza also wished everyone a Happy New Year. She congratulated all of the recipients of the awards tonight; our Public Safety Department is rocking and rolling. It’s so awesome to see that we have added some new people to the team and we were able to shift some things around and move people up. So, we’re really happy to see all of that. She stated she’s looking forward to 2024, is excited for all of the things that we have going on in the City of Cottage Grove, so, thank you. Mayor Bailey stated even though we haven’t really had any snow of consequence, this coming Saturday, January 6, is what they’re calling the Dust ‘Em Off Vintage Snowmobile Show and Swap, which is from 10:00 a.m. to 4:00 p.m. It takes place on the corner of Keats Avenue and 70th Street; it’s kind of in the farm field that’s across from Almar Village where Carbone’s, etc. are located. The Lions are going to be there, serving food and beverages. Council didn’t get a chance to be there last year and again this year because we’re doing our Strategic Planning meeting, but from the pictures he’s seen it looks like it’s a pretty large crowd that shows up for that event. If you get the opportunity to stop in and check it out, he’d encourage you to do so. Mayor Bailey stated tomorrow, Thursday, January 4, there are actually two hockey games taking place at the Ice Arena: Park boys vs. Roseville, and East Ridge vs. Cretin. So, it’s going to be a crazy event up there, and he thinks it’s the kickoff to the 50th Anniversary of the Ice Arena. So, if you’re a popcorn connoisseur, like he is, the popcorn is going to be back to prices 50 years ago, which is 50 cents. There will be other items happening this year, including a drawing for some free ice time and disco. If you’re interested, stop in at the Ice Arena to watch the boys’ or the girls’ hockey teams; watch the screen outside of the Ice Arena to see who’s playing and when. City Council Meeting Minutes January 3, 2024 Page 6 Mayor Bailey stated many people and staff have reached out to him today regarding the fenced-in area between Culver’s and US Bank, which is going to be Chase Bank. They’ve put the fencing around that particular area, and he will be sure to put that information on our social media, too. Council Member Garza asked with the area that they put the fence around, are we not having the car shows or anything there anymore. Mayor Bailey told Council Member Garza that the car show was moved quite a while ago down to St. Paul Park, at the Lions Levee Park. There were some parking challenges in Cottage Grove with Kohl’s and others, and Kohl’s was planning to sell that lot, so they decided to move it to St. Paul Park. Mayor Bailey stated our Workshop tonight in the St. Croix Room is open to the public. There are now three items in the workshop: The Dowdle Puzzle, the Kingston Park Building Design, and the 2024 Project Bonding. Mayor Bailey stated we will not be adjourning in here, but will adjourn from the Workshop. He stated Council will also be meeting together on this Saturday. 13. WORKSHOPS - OPEN TO PUBLIC - ST. CROIX ROOM A. Viewpoint Project Discussion - Removed from the Agenda B. Dowdle Puzzle Staff Recommendation: Provide feedback on the must-have and nice-to- have people, places, and things chosen to represent Cottage Grove in the Dowdle Puzzle in the attachment included in the report. Council and staff held an informational open workshop regarding the Dowdle Art Project and the next steps. Dowdle Studios has extended an invitation to the City of Cottage Grove to participate in the "Land That I Love" tour, which will commemorate America's 250th birthday starting in 2026. This tour, led by renowned folk artist Eric Dowdle, aims to showcase the unique stories and rich histories of various communities by partnering with a select few in each state. Recognizing the potential economic and promotional benefits of this endeavor for tourism and marketing, city staff organized a virtual meeting with the Dowdle team, which included Mayor Bailey and CVB Chairman Olsen. Following the meeting, it was decided that work on an agreement should proceed. On December 12, the EDA Commission approved the agreement, with some modifications related to items to be included in the painting (people, places, and things). City directors were tasked with brainstorming the individuals, locations, and objects that best represent Cottage Grove. The compiled list of ideas was shared with Council in the workshop. Council narrowed the list down to a proposed 18 people and 52 places: City Council Meeting Minutes January 3, 2024 Page 7 People 1.

The meeting was concluded, and Council and staff moved to the Training Room for the Kingston Park Building and 2024 Bonding Workshops. C. Kingston Park Building Design Workshop Staff Recommendation: Receive information and give direction on Kingston Park building concept designs. City Council Meeting Minutes January 3, 2024 Page 9 Parks and Rec Director Zac Dockter stated he’ll talk about the Kingston Park Building redesign. We’ve been talking about this for a very long time, but it got elevated to a priority this summer when we had the CIP discussion. Council asked us to start working on a concept design. Director Dockter introduced Andrew Cooper with Oertel Architects, who will be doing most of the presentation and will show you the concept designs. Director Dockter stated what we heard from Council at the CIP workshop was: 1) To increase restroom capacity and functionality. 2) Add a multiuse recreational room, similar to what we have in our other buildings. 3) Add space for general storage needs for events and programs; 4) Add a serving kitchen. 5) Accommodate additional picnic space. 6) Provide something unique, different than most of our park buildings. We did the concept design and held a couple of stakeholder meetings with our Parks Commission and also with some key stakeholders of the park. The additional information we heard from them has partly been incorporated into this design and will be incorporated into the final design: 1) Increase kitchen and serving window size, especially to the outside, so we can easily get food back and forth to the serving areas. 2) Consider the traffic flow for events that may utilize a kitchen and portable grill, so we can grill outside. 3) Maximizing picnic space was reiterated. 4) Address site electrical needs for larger events; that’s not as much a building design function, but certainly there’s an electrical load that needs to come from the building itself. We can hopefully work on those things simultaneously. 5) We got mixed reviews on the monument sign. Just remember, this is a concept design, so it’s wide open. If there’s anything you’d like to see differently, we’d like to hear your feedback. Andrew described the process that he and the rest of their design team took to the concept design and how we came up with the images that you’ll see. We brought our design team out to take a look at the park, which is huge; it’s really at an interesting juxtaposition, as a lot of neighborhoods surround it, and you have to weave your way through neighborhoods to get to the park. The educational element is to the east, and then it’s a road and farms on the other side. So, there’s a really unique location about this, a striking element of something that really registered with our design team and how we would create that within the building plan and the building program. Currently, the existing building has a unique shape but it’s not necessarily striking, it’s low scale with the roof shape, and its on a very large, open parcel of land. The park is entirely soccer fields and an upper plateau baseball field. Anything you have there is going to be very physical, there’s not a lot of topography that you’re dealing with, so something has to stand up and be visible. At the onset, we went through a series of critical spaces: The meeting room, the kitchenette, restrooms, to really understand those size parameters with the City staff. So, once we started putting those 20 x 30 boxes on the Site Plan for a certain space, we’d know how to orient it with our other support spaces, like restrooms and whatnot, and where it would point. Building: What you see here is kind of the manifestation of that building program. When we talked about the multipurpose room, it seemed that with an upfront, primary use of the facility, that needs to go out towards the parking lot. That’s what’s going to create City Council Meeting Minutes January 3, 2024 Page 10 the building geometry and that kind of striking view. Then we’d serve that with the ancillary spaces, such as the kitchenette, the storage and mechanical rooms, and then design an abundance of restrooms. Currently in this plan, in the women’s restroom, for instance, there are seven water closets and associated sinks to serve those water closets, and there are similarly seven fixtures in the men’s, three toilets and four urinals. For building code, you need seven of those for the space, so we are a little over and above the restrooms necessary for the actual building. But now you’re talking about a larger park, so it makes a lot of sense. Covered Picnic Shelter: We looked at a couple different options with the building plan of how we would orient and integrate a covered picnic shelter into the building architecture. Knowing that the playground is to the south and the bigger fields for the bigger kids are also to the south, it just made better sense to get more visual acuity from maybe a more populous game. Also, from when there’s more people using the playground, that split has that visual connection to the building, too, where the concession sales would be built. The concession sales is oriented to the south, as is the picnic shelter. We also want to consider in the summertime we have some harsh sun, so we want to create that shade opportunity. So, it’s not just a light picnic shelter, but it’s a fairly substantial picnic shelter that you’ll see in the images. Mayor Bailey asked how close will that picnic shelter get to the park, the play area; he asked because we have one particular point when he takes his grandkids over there, there’s only a couple seats around the perimeter of the park, and none of them are covered with trees. So, everybody finds the trees on the back side, and they sit under the trees, but not on benches. So, if it’s going to be closer, that’s awesome. Andrew pointed out the playground pad, which is closer than where it is today. More comments/discussion ensued: •Council Member Thiede asked if the trail is in the same place, that’s confirmed. •Andrew explained the red dot is where the existing building is, so you can see how we’re closing that in. •Mayor Bailey noted the existing building has indoor picnic tables, so it is taking it much closer; he said it would be so nice to sit at a picnic table or something up there. Andrew stated we’re expanding the existing picnic shelter and showed the existing trail that goes by the basketball court. •Council Member Garza noted the picnic shelter is covered, that’s confirmed. •Andrew stated as we’re coming up with the building program, first we need to make it logical for the size of the potential project, but it also has to fit within the existing infrastructure. There are utilities that come through the existing building, and we want to reuse those; so keeping the plumbing within the same general areas with this building makes a lot of fiscal sense. Also, if we don’t have to tear up the parking lot and the existing pathways to put a building footprint, we’re not disrupting the park’s use in general. Going back to the existing conditions, that covered shelter there is a good 40 feet away from the picnic shelter. Andrew stated he’d go through a series of images, as he talks about the design in general. We can always come back to anything that you might want to ask a question about. City Council Meeting Minutes January 3, 2024 Page 11 We looked at three design options: 1) A gabled roof, which is a more traditional park building. 2) A hip-edged roof that had a little bit more articulation at the front of the parking lot, so it would be a little flatter and then popped up, was a little more avantgarde in terms of its structure. It was a great design, but he personally thought it was way over budget even at that early concept stage, but then Zac and staff didn’t like it anyway. 3) This is kind of a simple mono-pitched roof that starts out low and crawls up to the parking lot, so that’s how tall it’s going to be at the parking lot. Director Dockter stated we’re looking at a series of stone and kind of residential Hardie Board type siding materials, so it’s something that’s off the shelf, it’s durable, but it’s not something that’s going to require a ton of maintenance. With park buildings, wood is great as long as we can get it up high; when wood is down low, it becomes an abuse and maintenance factor. There is a vertical monument sign, two things on this image: 1) That’s front facing, faces the sunset, so we’re proposing to take advantage of that, since we get great sunsets at Kingston. 2) It’s 50-50 on whether or not people like the monument sign. We also told them to be creative with the monument sign; it’s not his fault, but it’s not our standard rock sign. We can always mix that up. Mayor Bailey stated we already have a rock sign. Andrew stated one of the things we liked about this corner or just in general is the building isn’t out on the corner of the paths and the parking lot intersections, but it is a strong corner that you want to put something on there. So, even if it’s not a Kingston Park vertical monument sign, something that has way finding would be helpful; like softball fields this way, soccer fields this way, playground that way. So, there’s something there he thinks would be good; we just want to make sure that if something was there, that it’s as big as this, but it’s something that we think would look right with the architecture. Anything smaller and lower we’d still be okay with, but men in our office came up with putting the logo on the top of that design. With expanses of glass in the public area, there’s a considerable amount that faces north that doesn’t have a large sunscreen or overhang on it because you don’t need it there; you’re not trying to shade the sun from the north. And then we’re taking advantage of the western sunsets. Public Restrooms: Are accessed through the back of the building, outdoors, and then internally through a hallway to the community space. So, they can be secured if they’re not going to be open fulltime to the public. So, if someone is not using the rental space and you don’t want those restrooms open on a given night at 9:30, they can be closed and locked up. There is still a family restroom in the plan, that is located under the canopy; we’re looking at a wood structure, creating something that’s solid but not so heavy and weighted down. Director Dockter stated regarding the restrooms, operationally, we are keeping the family restroom open daily, and we would just open the other restrooms for large tournaments or the rental season. Andrew noted with these being the opposite side of public view, it prompted a lot of discussion, at the onset of the concept design development stage; Public Safety asks how are those going to be monitored and how are they going to be patrolled if a police officer cannot drive by and see people going in and out of them, how do they know that City Council Meeting Minutes January 3, 2024 Page 12 they’re occupied if they were open that day. There are a lot of different ways we could do that with lighting and security protocols; it’s not complicated, it’s just something that we have to think about going on into the project. Discussion followed: •Mayor Bailey stated these two bathrooms are on the very back side of it, and the family ones are on the corner of the pavilion. Andrew stated the family restroom is facing the playground, and it gets signed as such. •Council Member Olsen asked if those two face the trailway, but Andrew stated those two face the tennis courts; Mayor Bailey stated to Council Member Olsen’s point, they’re facing the trail. •Andrew stated if the community space was open in the evening for any reason, those restrooms would be 100% accessible from the interior space; those restroom doors would not be locked on the inside, they would only be locked on the outside, and you wouldn’t need them for egress, for exiting for any reason. Andrew stated we’re at about 2,400 square feet of covered canopy area in this plan, which is the same size as the whole previous shelter. So, it’s actually a little bit more than double the previous shelter. There are two-to-three picnic tables in the shelter now, while we’re at a dozen, comfortably, and we could cram even more in there if you’d like. He thinks it’s fairly comfortable seating. There’s also some permanent bench seating out beyond the canopy, so there’s still opportunity to kind of go in and out. Interior Space: Everything that we designed at this point in the concept design is we were provided with a cost estimate, and it’s very simple and durable on the inside: Polished concrete floors, standard drywall, impact resistant maybe, but still standard drywall on the inside. Everything is a stick frame, everything is wood framed; so, we’re not talking about a heavy masonry structure to try to keep this build economical. Using heavy timber and cross-laminated timber to be the structure, so the structure’s visible, it’s finished appearance is not something we have to treat once its up. So, less touches means that once a contractor puts it up, it’s done, and there’s not a painter that has to come by and refinish things. In this image, we wanted to show how we’d integrate lighting; there are fancy circular lights and a lot of different options. You can see the visual access to the playground from the indoor space. There is kind of a pass-through option for concessions or in the kitchenette; there is also a concession window that faces the interior, so there can be sales both indoors and outdoors. There is access to the restrooms, so that’s what would be permanently open as long as the community space is open. When we look at a facility like this that’s going to be used into the early evening, how does it also get lit because that is part of the striking appearance. Something that’s very inexpensive to do is to use colored LED lights. It’s something that can be very easily integrated in the architecture, it’s not an expensive feature, and is something that then creates a nice showpiece for the whole park. You can theme it for the Fourth of July, St. Patrick’s Day, Strawberry Fest, etc. You can choose colors for the day and it’s very easy to do. The materials are very simple, nothing super fancy, its just something that’s going to make sure to stand the abuse of children running around with their parents and running into the building. Discussion followed: City Council Meeting Minutes January 3, 2024 Page 13 •Council Member Olsen asked if the overhang itself was wood; that was confirmed. He was asked if there are any concerns about the sun fading that or causing damage. Andrew replied there are always concerns with fading a natural product, whether its wood or natural metal, which will also fade with UV. He personally doesn’t find it as a bad thing, as things age and patina naturally. He thought the wood canopy structure is not going to get hit with the sun, so that’s always going to stay that rich wood-tone color. The columns, on the other hand, would probably fade at different levels, depending on their sun exposure. Right now, we’re showing heavy temper in terms of the columns, he’s not sure its going to stay like that once we get through a design exercise with an actual structural engineer and get a more detailed cost estimate. There might be a scenario where there is steel up to a certain point and wood up above it, so that would lessen the amount of wood that would patina over time. •Council Member Olsen asked if they could also wrap the wood. Andrew replied yes, and they do a lot of treatment of wood products as a whole. They’ve also done some plastic, synthetic composites that look like wood. Some architects say if we’re going to use wood, let’s use wood; we had that debate in the office recently. When it comes to park buildings, it might be a simple project, but we know maintenance is a significant cost. It’s not the same as a pool house at a private residential development that’s going to get a lot of attention. It’s still going to get a lot of attention from Parks and Public Works maintenance staff, but it’s not a constant yearly upkeep, it’s more just kind of cleanliness. So, making it easy to maintain makes it a more durable project as well. •Council Member Garza asked with the wood columns, is there any worry that with our winter snow if that would eat up the wood at the bottom and if we need to be concerned about that. Andrew replied we’d be more concerned about any kind of steel connections that are down at the concrete level. If this becomes something that you’re going to plow and use in the wintertime, which is a possibility, if you’re salting that, then that becomes an issue. So, the details would be at a later design stage, but maybe a concrete post that comes up a foot and gives you a good base there. •Council Member Khambata asked what about the salt and degradation on the stone façade, is that all factored in as far as durability. Andrew replied synthetic stone and natural stone are naturally salt resistant. •Council Member Khambata asked as far as with the mortar joints and all that, will those hold up. Andrew replied he wouldn’t be terribly concerned with the products that we’d specify as synthetic products, it’s basically an epoxy-grade order, so its more plastic than it is cement. Once it gets put out there, brick and block will have some of that degradation downfall, but its usually just in that first eight inches. Again, specifying the right order of products will prevent that. •Mayor Bailey asked if that is solar. Andrew replied this is solar, he fully admitted its shown the wrong way in the image. Yes, there would be the opportunity to get solar on this roof. One of the benefits of using the heavy timber structure is that it can take the load, and solar panels are not as heavy as they used to be. There’s City Council Meeting Minutes January 3, 2024 Page 14 still a little load that has to be carried on them, so heavy timber would very easily be able to carry that. Mayor Bailey stated it would be nice to be able to do that. •Mayor Bailey stated he knows this is preliminary, but he has two other questions for Andrew or Zac. 1) He’s seeing those little white things and asked if those are rocks. Andrew replied yes. So, when we were looking at the Site Plan, one of the things that we had brought up to staff was he’s done a lot of work with the National Guard and they call it anti-force protection. We don’t have to worry about someone wanting to do harm on purpose to the building, through the parking lot, but he thinks we have to worry about someone accidentally trying to swerve and miss a child and drive off the curb. There is no curb there, it’s just a flat pavement, so we need some of those barriers, even with seating. It’s going to be necessary to do something there; otherwise, you have less than 40 feet of the traffic aisles. Mayor Bailey stated yes, we want something to prevent people from being able to hit the building with a car. 2) The roof is a flat roof. Right now, we’ve got a lightning detection system that’s on the current roof. He asked are we thinking about maybe adding that to here or are we going to put it separate. Director Dockter replied he hadn’t really thought about it, but we could do either or; those things are pretty easy to move and there are a lot of options for how we want it. Mayor Bailey stated if we’re going to do the solar or whatever the plan is, he thinks it’s worth having it and keeping it at Kingston. Director Dockter stated he thinks there’s multiple options for that, we’ll see how it works with the design. One thing is right now it looks like a spaceship with that on it, so, people might be wondering what is that thing; Mayor Bailey stated it would be the only thing you’d see on the top of it. Director Dockter stated you’d have to get a long ways away, in fact, you might be able to see some of the lightning spires as you’re driving into the park from the far west side. Other than that, he doesn’t think we’d see much of the lightning protection unit. The existing building is much shorter and we’re dwarfing it with the new plan. Once we get to the final design, and we’re actually putting structural steps to stuff, we might need to get it built a little taller than this. •Council Member Garza stated she thinks it’s a beautiful design. Andrew stated he appreciated that very much. He can’t take most of the credit, but Jensen and Maddie in our office did a lot of the initial renderings. They look like they take a lot of time, and they do, but they whipped these out so fast for three different design options. The staff got three design options of all similar design quality to really choose from, and whittled them down based on recommendations that you guys had given them. They were also pragmatic choices. •Mayor Bailey stated he likes it, now we get to the price point. Andrew asked if there were any questions, but none were asked. •Mayor Bailey stated it’s a beautiful building, and is obviously one of our important parks in our community. •Council Member Olsen stated it looks fantastic. And its very functionally logical. City Council Meeting Minutes January 3, 2024 Page 15 •Council Member Khambata stated he likes the amount of thought that went into orienting the overhang so that parents and people can sit and watch the kids play in the park and it’s oriented for catching sunsets to the west. In his opinion, it has a similar appearance to the Glacial Valley building, just with the flat roof and so on. He still thinks this is a very unique building and he really likes the overall design. •Council Member Olsen stated our Lions Club is going to think they died and went to heaven if they get to work out of this building on the Fourth of July, etc., so that will be good, too. •Director Dockter stated it turned out we had some good numbers as stakeholders. •Council Member Thiede stated of all the people, it should be the Lions Club that will like it. Mayor Bailey agreed, and noted the One Family people will like it, too. Mayor Bailey stated for the size of our park there, he asked Council about the corner sign, as Director Dockter stated they were 50-50. Personally, he thinks its fine, he doesn’t see an issue with it. Council Member Olsen stated he thinks its fine. Council Member Khambata stated he doesn’t love it, but he’s not gonna fight it either. Mayor Bailey stated that’s what he’s saying, it’s not like it’s the end of the world. It’s funny, to your point, the thing that he usually hears about when he’s over at Kingston, other than the outhouses, is where’s the bathrooms in the building. So, the way signage that shows where the restrooms are or the family restroom is here would be nice, not that it has to be on that corner thing. He thinks we need to have something different there, it doesn’t have to be the rock that we have at the beginning, coming into Kingston. Director Dockter stated so, no help on the sign. We’re still at 50-50. Council Member Garza stated she likes it, she thinks it makes it look modern. But Cottage Grove is so hometown, so, to her, that seems like St. Paul. It seems so modern, but then she still likes it. Director Dockter stated we liked the vertical, we could try this a million different ways with their staff. Mayor Bailey stated he agreed with Director Dockter’s comment on the vertical. He thinks if we’re going to do something there, we need to have it in proportion to the building. If we have just a sign lower to the ground, he doesn’t think the feel will be there. So, if we’re looking at something, whether it says Kingston Park with the logo on the top, you guys can kind of figure out what makes sense. Is it backlit, is it lit at all? Council Member Khambata stated he knows this is only a concept, but whatever type of stone you’re using for the force barrier there, what if you did like a mill piece of that, taller and kind of narrow, kind of with a light material, and then we use it as like a wayfinding point of interest and have something like that on top. It would like more like a traditional monument, it would be incorporated into some similar stone, but it would still be an imposing feature to mimic the architecture. City Council Meeting Minutes January 3, 2024 Page 16 Council Member Olsen stated but you’re saying you want something different than the existing stone. Council Member Khambata stated yes, because that, in his mind he sees like a piece of like black onyx or black marble with white lettering on it, and he feels like that kind of enhances it. Mayor Bailey stated like the Ravine Parkway stone with a message on it might be an okay thing, too. Administrator Levitt stated what if we thought more about art, a vertical art-type feature. We did something unique at the HERO Center; Mayor Bailey stated that’s true. Council Member Khambata stated that’d be cool. Director Dockter stated that’d be a great corner for public art; Council Member Olsen stated it really would, wouldn’t it, so why don’t you guys think on that and see if you can come back to us with something. Mayor Bailey asked if there is a wall big enough in this building where we could put the new puzzle artwork. Administrator Levitt stated that would be unique. Mayor Bailey stated it would be kind of cool to have it there on the wall for Strawberry Fest. Council Member Garza agreed. Mayor Bailey stated it looks like people can see in there, so it might be a good spot for our design. Council Member Olsen stated we’re clearly on the right track here now and asked Director Dockter if he felt good about it; Director Dockter replied he loved it. Mayor Bailey asked if the thought process here at some point is that programming is going to happen out of there; Director Dockter replied yes. Mayor Bailey stated he kind of figured that. Council Member Olsen stated with the size of this building, of course you would. Mayor Bailey stated we just haven’t had the chance before. Council Member Olsen stated he thinks Molly would tell you right now that it's going to be necessary. Director Dockter stated yes, with the neighborhood demographics there, it’s going to be. Administrator Levitt stated the only caveat is from a funding debt management, you’re probably not able to fund this bid until like 2026 because this is a lot more than $600,000. Council Member Thiede stated we’re using the Financial Management Plan (FMP), and remember that FMP is not just looking at the next 10 years in keeping the average under $100, but looking at any 10-year span and keeping it under, averaging $100. Brenda Malinowski, Finance Director, stated that’s correct. It doesn’t fit into our bond potential for 2024 and probably not 2025, but we can look at 2026 or 2027; maybe build in 2026 and then bond for it in 2027 when we have capacity. Mayor Bailey stated remember we’re in 2024 now, so, the likelihood of building it this year is it’s not going to happen. So, we’re either looking at 2025 or 2026, and we have to fit it within other significant projects that we have coming in from a bonding capacity standpoint. As much as he would love to build this tomorrow, the reality is there are some other projects and things that we’re going to have to make sure that we manage our Debt Levy. Administrator Levitt stated and by budget time, we can respond to the design, define the cost estimate, and then we have real numbers to look at. Mayor Bailey stated he’s heard from the Council that we all love the design. It looks good, love the little touches, like the fact that we’re going to have solar on the roof, maybe working on the art on the corner idea, whatever that may be. He wants to see City Council Meeting Minutes January 3, 2024 Page 17 what the art is in our new Glacial Valley Park building, not for this, but it kind of gives him a flavor. Director Dockter stated the next step will be we’ll negotiate the terms for the design and bring that back to Council for review; we’ll get that on the schedule. Once we get the design, we can confirm the budget, and go from there. Mayor Bailey thanked Andrew and Director Dockter for the presentation. Director Dockter stated the Ice Arena is 50 years old, which is very neat. We just celebrated the 30th Anniversary of River Oaks last year. So, a lot was going on in 1974, when we were building the Ice Arena, there were the Wakota Ice Arena in South St. Paul, Aldrich in Maplewood, and West St. Paul built something, so there were only three other rinks in the metro. This Ice Arena was built for both Cottage Grove and Woodbury, because 50 years ago Woodbury didn’t have an Ice Arena, and they didn’t have their own football stadium. When he played hockey, Woodbury played at our rink. So, a lot has changed over the years, but he thinks the Cottage Grove Ice Arena holds a place in many peoples’ hearts for all the events and uses, because when they talk to people and say Cottage Grove, if they’re skaters, they will say you guys have that nice Ice Arena. So, we are selling apparel, sweatshirts, YETIs, etc. There’s 50-cent popcorn tomorrow as Mayor Bailey mentioned. We kind of scheduled one event per month, then after the six months, we’ll see how those events go, and then we’ll figure out what we’re going to do the following six months: January is 50-cent popcorn; February is buy one, get one hockey tape; March is 50-cent coffee, fountain soda on special event day; April-You can enter to win one free hour of ice time; May-1974 Disco night, skating disco on the rink; June-50% off public skating all month. So, it’s going to be a lot of fun, and we’ll schedule more events in July. D. 2024 Project Bonding Workshop Staff Recommendation: Receive information on the 2024 Pavement Management Project and 2024 Bonding Capacity, and provide direction on the final scope of work for the 2024 Pavement Management Project. Amanda Meyer, City Engineer, stated the purpose of this discussion is to talk through those projects that are related to pavement rehab, as well as those projects that are being bonded for in 2024. In 2024, we have the Mill and Overlay, so we have five miles of a two-inch Mill and Overlay in our Thompson Grove neighborhood. Over the last couple of years, we’ve been working throughout that neighborhood and will be finishing that up in 2024. Project Cost is estimated at $1.2 million; that includes a cost share with St. Paul Park, as there’s a portion of 85th Street that extends over into St. Paul Park, so, we have already started coordinating with them for that work. The next project to highlight is the South District Street Utilities, Phase 2, in the southwest corner. We’ve been working on that project over the last couple of years. The phase for 2024 is to finish out some of the utilities, but it’s really the street construction, landscaping, lighting, and pedestrian facilities. It will provide that secondary kind of City Council Meeting Minutes January 3, 2024 Page 18 emergency access down to the River Acres neighborhood, as well as the Graymont Village neighborhood that’s being constructed right now. It includes mostly new construction, but there is some reconstruction of just under ½-mile of the 15 roadways with that realignment of Hadley, 100th, and 103rd. Total Project Cost remaining is estimated $5.25 million. We wanted to highlight East Point Douglas & Jamaica, Year 2: We have about ½- mile left of reconstruction of East Point from the temporary signal that’s between the Holiday East, Top Ten, and Taco Bell area to just east of Wells Fargo. And then about a ½-mile Mill and Overlay that would then extend down to about the VFW. She noted we have the Utility and Engineering Building down at 110th and Ideal, which is not pavement rehab, but is part of our bonding in 2024. Engineer Meyer stated the bulk of our presentation for this evening is our 2024 Pavement Management Projects. The red streets highlighted on the screen before you are those areas that were identified when the feasibility report was authorized in May. That feasibility report helps us to analyze the streets and understand project scope and financial feasibility. During the CIP workshop, we also understood that with all of the streets that were being proposed as part of pavement management, with the inclusion of Jamaica, from 80th Street to 90th Street, we knew that there would not be enough funding to do all of these roads. We talked about pulling out East Point Douglas, both from a financial perspective and also just from the perspective that we’re already impacting the commercial area of East Point Douglas and Jamaica. So, we’d maybe not want to impact a second commercial area at the same time. She stated Ryan Burfeind, Public Works Director, would talk more about the feasibility study. Director Burfeind stated he’d build on what Amanda said; we had a few workshops in August, and we talked about everything that we’d authorized from a pavement management perspective. Jamaica Avenue had kind of been added in because that road has just been deteriorating so quickly in the last few years that the rutting is extensive, it has frankly become a safety issue. The ruts are actually up to two inches deep as you approach some of those intersections. Now, last winter and this winter, we just can’t get the road clear because the nice, even blades scrape over it with two inches of snow, and then in the summer, cars are hydroplaning. So, we really want to figure out a way to get Jamaica Avenue into the project. We looked at a couple different ways, which he’ll talk about, to do that. What’s unique is with that amount of rutting, there’s not a huge benefit to just replace the pavement. If you remember at Norris Square on 80th Street, we just replaced the pavement, it didn’t have the rutting issues as there’s not as much traffic and a different structure. If we just replace the pavement, that rutting is likely to come back. We might as well do just a Mill and Overlay, as essentially, we’d get almost the same benefit for a lot lower cost. To do more, we’re really looking at like a structural fix, actually doing a stabilized base, like we did on West Point Douglas Road; that’s very expensive, and that would quickly eat up all of our capacity for pavement management for next year. He really has a different vision for that road in the future. It’s a super wide road, it’s much bigger than it needs to be. Its got shoulders, two little four-foot sidewalks, and no boulevard. There’s no place to store City Council Meeting Minutes January 3, 2024 Page 19 snow, and we’re going along a road that’s 50 MPH and 45 MPH, and he wants to change that. It doesn’t really feel like the right time to do a major reconstruction of that roadway, because that’s going to push it out so far. What he would like to do is really do something more minor, like the Mill and Overlay, which we’ll talk about, but that’s going to fix the issues that need fixing. It will give us a smooth roadway and will fix the rutting. Down the road, his vision for Jamaica is to make it a more pedestrian-friendly roadway. Director Burfeind stated to really redo the road, there’s not an in-between option to just replace the pavement; the Mill and Overlay is going to get you a similar life cycle because it’s really the rutting that’s going to come back first. Council Member Olsen asked what’s the subbase on that road. Director Burfeind replied it’s gravel, but it’s a lot thinner section than we’d ever do nowadays. So, we’re really talking about doing like we did on 80th Street. Council Member Olsen stated so, you’d have to do a full reconstruction. Director Burfeind confirmed that and stated it’s a massive cost. So, we might as well do the Mill and Overlay at half the cost and get almost the same benefit. Council Member Olsen asked how far down on the Mill and Overlay. Director Burfeind replied so, what we looked at was a two-inch Mill and Overlay, with a little more detailed Mill and Overlay. So, we’re talking about actually fixing all of the joints, too, because obviously the joints are pretty separated. So, this is a little more extensive than a residential neighborhood Mill and Overlay project, but it’s still something that’s going to get us 10-to-15 years more of a good ride quality life. And then we can really program that major project someday where we’re probably doing overhaul of the medians. He’d like to see getting more boulevard space in the future, actually eight-foot trails, something you could actually ride your bikes on, etc. So, that’s kind of what went into this Jamaica Avenue portion of the project. Like Engineer Meyer said, when we talked at the CIP, we knew we couldn’t do everything. We wanted this feasibility report to really figure out where is the best place to spend the money. East Point Douglas was removed just because, like we said, we can’t impact both of our commercial areas in one year; that’s just not a good way to do business for our residents. So, with the first option, obviously, you can see it still leaves some very high costs and it’s just with a Mill and Overlay of Jamaica. What we’ve found is in that neighborhood, the ten years that he’s been here, every time we do a Pavement Management, we do a feasibility study, we do cores, and road stripping. We’ve talked about asphalt stripping for probably more than ten years, we pull the cores out, and they fall apart, which means the road is in terrible shape. We did all of our cores in the neighborhood on the left, the Hillside Trail, Thompson Grove Estates, and those cores all held together; there are some of the early signs of stripping, but there is no extensive stripping going on. He was shocked, as it’s the same era of pavement of all the other pavement managements that we’ve done, just this past year, the roads were in terrible shape. That was pretty eye opening, we really do have a good three-to- five years of life left in that road. We really didn’t feel like it’s the best use of money at this time; you want to maximize your life out of a roadway, so that was very surprising. It's the same mix, same era, same MnDOT specs, and he doesn’t have an answer on City Council Meeting Minutes January 3, 2024 Page 20 why that road is not stripping. It’s a good thing, we want roads to have good conditions, it’s a good problem to have, but frankly, it was surprising. So, this was basically the first look, if this is everything. We took East Point Douglas out and it wasn’t on there. Option 2: We took the neighborhood out, the neighborhood proper, but we looked at what if we keep Hillside Trail. Hillside Trail also does not have stripping, but it has a lot of traffic with 3,000 cars a day over the last 20-to-25 years. So, that road sustains more wear and tear. When you drive Hillside, you know this could use a rehab. We looked at what could that be if we do just Hillside with Jamaica and with Prestige Estates. We know Prestige Estates has to be done, that’s a full reconstruction, and it’s got to happen. Hillside Trail has all the storm sewers for the whole neighborhood. Nowadays, we have catch basins and storm sewers out in neighborhoods. Back then, they put it all in the main road, and all those neighborhood streets drain to Hillside Trail. And that storm sewer needs work, it doesn’t need a full replacement, but the whole thing needs a lot of work. So, what that does is it puts all the burden on those residents on Hillside Trail; it should be spread out over the neighborhood, as they all use that storm sewer. So, if we do Hillside Trail alone, it results in an estimated assessment of $7,700 just for a spot curb replacement. If you remember this year’s project, the estimate was $5,000, and it came in at like $4,400 or $4,200; so, that is a huge burden to put on those residents, and that one really should be equal across the whole neighborhood. He actually drove this road with Gary Orloff, as he’s the guy who maintains these roads. Because its not stripping, its not falling apart, it’s just there’s a lot more cracking, they have to do the blow patching and things like that. Really, these neighborhood streets are manageable; they’re low speeds, so it’s an easy, safe place for his crew to be doing work. We don’t want to push something off if it’s not manageable from a maintenance perspective, but he felt very comfortable when I talked about this three-to- five years and keep it with the neighborhood proper. The Special Benefit Appraisals, frankly, wouldn’t force a $7,700 assessment for spot curb. We know that last year’s Special Benefit Appraisal he thought was $5,800, so you’d actually see the City have to pick up all that additional cost, above and beyond. So, it’s kind of a unique situation, but Gary is very comfortable with the idea of potentially maintaining Hillside for that three-to- five year period, kind of re-shifting how we do those roads over the next year. Option 3: We looked at Jamaica and the neighborhood, so it’s still a very good project. Jamaica and East Point worked. The fact that we’re looking at Jamaica is a huge excitement for me, Gary, and his crew. That was the best thing they could hear because Jamaica is a dangerous place to do maintenance and an expensive place to do maintenance because we have to use blocker trucks for anybody turning, and we’re closing lanes, and it’s a challenging thing. We know Prestige Estates needs the work done, too; that’s one that’s kind of been pushed off because it is a full curb replacement. So, there was a for that, it’s a full curb replacement, let’s get the whole length out of that. But we’re at the point where that project needs to be done, so that lands us with this amount of bonding, just under $3 million and a $3.3 Total Project Cost. It’s still a decent-sized project and especially if you look at all the investment happening next year City Council Meeting Minutes January 3, 2024 Page 21 in our roadways, with all the other projects Amanda spoke about, it’s still a major investment in our system. This really is the best use of our funds for next year. Council Member Olsen asked Director Malinowski what’s our debt capacity this year for this project. Director Malinowski replied last year, at this time, we were working on our FMP. When we went out for bonding for our 2023 projects, we did our ratings call with S & P, this is what we showed them on top is that this is what we were going to bond in the next five years. So, they not only got our FMP, they got our bond issuance costs, and so, they are expecting us to come in at $18 million, so, that is what our bonding capacity is for 2024. So, that is the number that we’ve looked at a couple different times; we know we got the bond rating upgrade last year to AAA, so, we’re very new at our AAA rating. So, if we want to think about what we told S & P, in that bonding, we’re about at $18 million. Council Member Olsen stated okay, so with the three project options that were shown, Option 3 appears to be what Ryan is trying to sell us. So, what does that do, relative to our debt capacity or our bonding capacity, and how does it fit within that. Director Malinowski replied it does fit within that. At the bottom of this slide here, what we have on the second line there is the Pavement Management for $3 million, the pavement management at Jamaica and East Point Douglas $3 million, and then Equipment Certificates we need to issue for some of our equipment, and then that leaves us $12 million for a Utility Building. So, we’re increasing our Utility Building bonding is what we’re suggesting; it’s still staying right within that $18 million. The reason that we’re suggesting that maybe we want to think about bonding more for the Utility Building is as we’ve gone through the last 12 months, there’s been some things that have come up. Council Member Olsen stated and it will take less pressure off the utility fees, too. Director Burfeind stated some of the other things, like Brenda mentioned, is the State assistance. That $1 million State assistance overhaul, which we found to be frankly necessary, that really wasn’t in the works when we were talking about the Utility Building, and maybe we could use more cash. So, that was an extra $1 million the Council authorized, which the Utility Division is very excited for that project that’s in the works. The other one is our water tower. We do know we need that new water tower in the Low Zone; we kind of had to take a pause because water tower pricing went through the roof last year, with the steel. We’ve kind of reorganized that, we’ve re-reviewed all of the modeling, and we did our Comp Plan, and we think we can maybe do a little different tower to save some money. But, we might potentially have to use some of that cash to help cover that water tower because we do need it. Council Member Olsen stated so you want to bond to offset that; Director Burfeind replied, yes, that could help us. Council Member Olsen stated and we’re still going to come in at or below what we projected; Director Malinowski stated for what we disclosed to S & P, yes. Council Member Thiede stated we’re coming in at $430,000 above it; Director Malinowski stated for right now, with these numbers, yes. City Council Meeting Minutes January 3, 2024 Page 22 Council Member Olsen stated these are estimates. Director Burfeind stated this is really probably the most conservative scenario because we took this off the Utility bidding, we took bids, and those bids were a little bit under. We still have all the project contingencies in the Construction Manager’s contract; not that every project is the same, but he thinks for Glacial Valley, he doesn’t know if those were hardly touched at all from a contingency perspective. Also, we are pursuing funding from the State for our building. So, he has a $1.2 million request into them. Based on, Woodbury kind of went through this, he thinks the bare minimum they’ll authorize is $600,000. If they try to authorize less than $600,000, then we’ll have to fight them, basically, because he thinks we deserve that. There is money that should buy that down. Council Member Olsen stated they’re going to do another bonding bill this year, too, so, you guys are working through that; Director Burfeind agreed. Mayor Bailey stated but you have to decide what you’re going to ask for. Council Member Olsen stated that’s his point, you have to decide what you’re going to ask for. Director Burfeind stated that this $1.2 million is actually from the 3M Settlement. So, this is actually because we have to do the Water Treatment Plants and house them. Council Member Olsen stated he’s very glad Director Burfeind is confident. Director Burfeind stated it does show slightly above, but this is really the most conservative, worst case scenario. We should know about that 3M Settlement request in the next few weeks. Council Member Olsen stated okay, so if you drive around town, there’s lots of opportunity out there relative to road maintenance, there just is. We’re seeing a lot of opportunity on Hardwood because of the additional traffic, the truck traffic, for the development. East Point Douglas we all know is in need of some help. To be frank, there’s probably still some neighborhood projects out there that need to take place. So, let’s take a five-year view or a ten-year view, understanding that you want us to do this, with the bonding this year, how does that play into our strategy next year, the year after, the year after. He knows we’re waiting on some MSA funding, for example, to get some of these other bigger projects done because we borrow against that. But are we still going to be able to keep up with the other stuff that needs to get done, because it’s not going to go away. Director Burfeind stated that’s correct. Anytime we talk about not doing something, it doesn’t just disappear. There are two things we have to do: 1) When he talked about his new Mill and Overlay plan, and he talked about doing a combination of Mill and Overlays and rehab, we’re looking for about eight miles of work per year. We actually are hitting that, even with this new plan. So, we’re actually right on, that’s our goal, the eight miles per year keeps us on that four-year cycle, between the Mill and Overlays and the reconstruction. So, we actually are hitting that, even with this, just because of all the other projects. It’s not just the pavement management next year, there are so many projects fixing roads. 2) Also, just as an engineering group, he thinks we need to basically look at our next ten years of pavement management. We had this good news of roads that doesn’t have stripping, so maybe we’ll take more cores in the City Council Meeting Minutes January 3, 2024 Page 23 neighborhoods just to feel comfortable with the future years. He thinks coming up with basically a revitalized ten-year Pavement Management Plan would be very beneficial. Council Member Olsen stated it’s a blessing that we don’t have to deal with Hillside now, that’s probably an unexpected thing based on previous core samples. There are still going to be issues with those neighborhoods; he thinks we’re going to have to be very prescriptive with regard to what we’re going to do next year, the year after, and the year after if we’re going to stick with our budget planning. Those roadways are going to continue to be heavily traveled. So far, we haven’t had a lot of freeze, thaw, this year, but that always happens, too. It just makes him nervous, he doesn’t want us to fall behind. Director Burfeind agreed. Mayor Bailey asked Director Burfeind about the water tower, when are we planning on doing the water tower. Director Burfeind replied 2025, next year. Mayor Bailey stated he was told that Woodbury is asking the State for money for a water tower. Director Burfeind stated in Woodbury’s vision, in their mind, with a new Water Treatment Plan, putting all their treatment and then just treating their city in one spot. Right now, they have 20 wells that individually go into their system. They’re modeling everything; he’s actually had some conversations with their director about it, they feel like they have to have new water towers at that treatment plant because of the treatment plant. The State will not pay for that; he thinks they’ve tried to have the 3M Settlement to pay for it, and it won’t, they said no. Director Burfeind thinks that is fair. He said we’re a little different, where most of our wells already went to one spot, where we’re building that Intermediate Zone plant; it already went to one spot, it went to the City. So, we aren’t really changing our operations, how we distribute water, but Woodbury feels like they are, and that’s what they’re kind of modeling everything, so. Mayor Bailey asked if we knew where theirs is going, are they going to try to get bonding money for that. Administrator Levitt replied she didn’t think they were seeking bonding dollars. Mayor Bailey stated okay, he heard they were, that’s why he was asking. Council Member Olsen stated they’re just going to have to figure it out. Administrator Levitt stated it’s difficult because Woodbury is dead set on one Water Treatment Plant for their entire city. We don’t believe in that mindset; we believe, and she thinks the State is recognizing, that there’s a lot of additional costs in what they’re choosing to do. So, Woodbury will have to absorb more cost for piping and other things. Council Member Olsen stated or they could change their plan; Administrator Levitt stated they’re refusing to. Director Burfeind stated the State actually approved the Settlement Plan for two plants in Woodbury, but Woodbury only wants one. So, they have to pay the difference, the upcharge to do one. Mayor Bailey stated he was just curious. He knows we’ll be talking on Saturday about grant opportunities, etc. out there to see if there are some options that will help pay for things that we know we’re going to need at some point. City Council Meeting Minutes January 3, 2024 Page 24 Council Member Olsen stated in terms of maintaining the debt integrity of the FMP, Option 3 is the best way for us to do that. Director Burfeind stated yes. Council Member Olsen asked Director Malinowski if that was accurate. Director Malinowski stated it is accurate, but that’s not the reason, but it does work into the plan the best. Council Member Olsen said the reason he’s asking is again, we’re lucky, we have some areas we were planning on that we don’t have to deal with, but we will have to deal with those. So, we’re going to have to keep our nose to the grindstone in terms of seeking third-party funding, like Ryan said, reevaluating and doing some additional testing. It’s just something we’re going to have to be really cautious about. If we can maintain the integrity of the FMP, that’s an added benefit and a win. Council Member Garza asked a question on Option 2; she knows it sounds like it’s not an immediate concern that we need to work on it, but once we get there, is there any opportunity for sidewalks. Because between the school and the park, she lives near that area, and the kids are on bikes up and down, and Hillside is a fast-traveled road. People fly down that road, so it’s just concerning. Director Burfeind replied that’s something we can always review with a feasibility report. So, we put some sidewalks in the median here, along the side here on 90th Street. It’s always interesting how contentious they can be, even though the people are walking there today in the road, you put them on a sidewalk, but he thinks it’s always something that we can look at. Council Member Olsen said sidewalks and lighting. Council Member Garza stated in between the schools and the parks, like she said, she’s lived over there now for years, and it’s a fast-moving road, and it would be a good opportunity to have some sidewalks. Mayor Bailey stated it’s a good point. Since we’re putting it off for a while, it might be something we can take a look at. He just remembers when we did this over on Hadley, we wanted to put sidewalks along Hadley, by Pine Hill, the homeowners over there just beat us to heck. Council Member Garza stated she’ll go talk to the neighbors. Council Member Thiede stated talk to the neighbors and get them all excited about it. Council Member Garza stated she’ll tell them that your kids won’t get hit by a car. Administrator Levitt stated we looked at that sidewalk, she thinks about 17 years ago, and at that time, the neighborhood didn’t want it. Director Burfeind stated with something like that, to engage them, we have to have really focused neighborhood meetings on that, on sidewalks, to get the neighborhood involved. Administrator Levitt stated that does provide the opportunity for that, we’ll get the design of it, and if you do it with the neighborhood as a whole, you start to find out if it’s going to go. Council Member Garza stated and you did so much work on that park over there and there’s so many things that people can use, that park and the ballfield in the back, and there’s an ice skating rink there. So, it’s a pretty busy park, between Hillside and that, there’s also an elementary school. City Council Meeting Minutes January 3, 2024 Page 25 Council Member Khambata asked so with the eventual reconstruction of Hillside, would you take that opportunity to branch out off of Hillside with the storm sewer system. Really, right now, is the water literally just running the length of the street through the gutter and then congregating at Hillside. Would you move that back and have some catch basins further down on the side streets? Director Burfeind replied so it all runs the whole length right now. Actually, in three- to-five years, it’s still just a spot curb replacement job. The curb is actually in amazing shape out there, so much so that three-to-five years won’t change it. So, it’s really just replacing that pavement. Usually, when you add storm sewer, that really happens when you replace the entire curb because you end up having to dig up all of that curb line for boundaries. One thing he will say that’s amazing here is if you look at Indian, any big rainstorms up by Ideal Park, that road turns into a pond for a short period of time. We actually don’t get that on Hillside; surprisingly, the amount of catch basins they have on Hillside really can capture that water. We haven’t had any ponding issues, but certainly some day, with the full reconstruction, that’s something we always look at. Council Member Khambata stated he thinks it’s hard to argue with Jamaica; that’s the one that’s bad. Council Member Olsen stated and you say the Mill and Overlay is going to give us at least ten years. Director Burfeind replied yes, we actually went and looked because we actually did a Mill and Overlay on a part of 95th Street, that was heavier rutting in 2013, coming out of the marshalling yards. Actually, down there, there’s about 1/3 of an inch of rutting; it’s just starting to kind of come back after ten years. And that gets significantly more heavy truck traffic than Jamaica does, so, that was a good kind of example of what to expect. Council Member Olsen stated if you mill down a little more, you can give yourself a little more stability. Director Burfeind agreed. Council Member Khambata stated he’s in favor of Option 3. Council Member Olsen stated yes, me, too. Council Member Thiede stated yes. 14. WORKSHOPS - CLOSED TO PUBLIC - None. 15.

Mayor Bailey called the meeting to order at 7:00 p.m. 2. PLEDGE OF ALLEGIANCE The audience, staff, and City Council Members stood and recited the Pledge of Allegiance. 3. ROLL CALL City Clerk Tammy Anderson called the roll: Mayor Bailey-Here; Council Member Garza- Not present; Council Member Khambata-Here; Council Member Olsen-Here; Council Member Thiede-Here. Also present: Jennifer Levitt, City Administrator; Kori Land, City Attorney-LeVander, Gillen & Miller, PA; Tammy Anderson, City Clerk; Ryan Burfeind, Public Works Director; Gretchen Larson, Economic Development Director; Zac Dockter, Parks and Rec Director; Pete Koerner, Public Safety Director; Brenda Malinowski, Finance Director; Mike Mrosla, Senior Planner; Emily Schmitz, Community Development Director; Jaime Mann, Interim Communications Manager & Assistant City Administrator. 4. OPEN FORUM Mayor Bailey opened the Open Forum. Bonnie Matter, 6649 Inskip Avenue South, spoke about Consent Agenda Item J, the South District Street & Utility Improvements. She stated there were three documents attached, and she requested that the Feasibility Study that was done for that project also be included with those documents so that the complete story is there. The Feasibility Report was for south streets, 105th Street that connects Hadley to Ideal, and there’s also a loop that goes to 103rd Street. The Feasibility Report was done in March City Council Meeting Minutes January 17, 2024 Page 2 2022, and it was presented at the March 16, 2022 meeting; it’s very detailed, and in addition, it lists the cost, around $14.8 million, and it breaks down who’s going to pay for what and exactly what’s going to happen. The reason she would like that report out there, attached to those other documents and kept with it as part of the project plan, is that there’s a lot of development and a lot of street planning and road planning that’s going on out there. It would be very nice to be able to access these things and review them as a complete packet. As no one else wished to address the Council, Mayor Bailey closed the Open Forum. 5. ADOPTION OF AGENDA Council Member Olsen made a motion to approve the agenda; second by Council Member Thiede. Motion carried: 4-0. 6. PRESENTATIONS A. Retirement Presentation - Kevin Zittel Staff Recommendation: Receive Kevin Zittel’s retirement presentation honoring 30 years of service. Mayor Bailey stated this is a retirement from the Public Safety Department of Firefighter Kevin Zittel. Mayor Bailey invited Kevin and the Council Members to join him in front of the dais. Public Safety Director Pete Koerner thanked the Council for giving us this opportunity to recognize Kevin. Over the last couple of years, the Fire Department roundtable came up with a really good comprehensive plan on how we recognize employees, starting at five years and ten years, but we didn’t include people at 30 years. Kevin has already had a retirement party, which was well attended. In April, we’ll be doing Fire awards where again we’ll recognize many of the employees. Mayor Bailey and the Council actually came to him and said we have to do something for a 30-year employee, it just doesn’t happen. Kevin is the fourth to hit that number as a parttime employee, which is an incredible number, as he’s also worked with Public Works. Director Koerner stated he’s known Kevin since middle school, we played sports together, and Kevin started his employment in October 1993. Back then, we didn’t have all of the safety things we do now, but Kevin’s been a part of a lot of the changes with the response model and equipment. When he was the Safety Officer, he wore the blue helmet for a while, and Kevin was always passionate about safety, not only on the Fire Department, but he was also on the City’s Safety Committee. He was kind of ahead of the game with community risk prevention, different injury prevention things, as he was doing that 25-30 years ago. Director Koerner listed Kevin’s accomplishments: Safety, Water Rescue Dive Team, and Safety Camp for many years. He started the Youth Fire Prevention Program with the Youth Service Bureau, was involved in car seat safety. He does a lot with EMT City Council Meeting Minutes January 17, 2024 Page 3 services, he was always a fixture at the fieldhouse, doing various EMT events. He had leadership roles as both lieutenant and captain. You probably don’t recognize Kevin without his hat on, but when he really looked at some of the highlights, Kevin taught CPR and thousands of people have come through that program. He did that as a part time employee, scheduled training for countless businesses; he did CPR training for my daughter and son, and they loved it. Director Koerner stated Kevin has had an incredible career, 30 years is remarkable, and he deserves to be standing here tonight with the Mayor and Council so they can thank him. Mayor Bailey thanked Kevin for his many, many years of service, it’s impressive to say the least. He noted his family is here tonight, as well as many of his firefighter partners who have worked with him over the years. There are a significant number of hours that firefighters put in for training and issues that happen, no matter what hour of the day. The firefighters’ family events often get interrupted, but our City could not function without individuals like Kevin and all the firefighters. As much as he’s sad to see Kevin go, he’s actually excited for his future and for him to have more quality time to spend with his family. He thanked Kevin again. Mayor Bailey read aloud the plaque from the City, which was then presented to Kevin. On behalf of the Council and all the citizens of Cottage Grove, he thanked Kevin for his many years of service and commitment to the community. Everyone applauded. Kevin stated he didn’t really prepare a speech, but he just wanted to thank the City Administrator, Council, and all the leadership team. He and Director Koerner have been through a lot together. It just so happens he had a couple days with Chief Pritchard, who was his sixth Fire Chief in 30 years; he told Chief Pritchard that was why he retired, because he couldn’t break in a new chief. He thanked his brothers and sisters here in the back, the new firefighters, and those who have been with him for a long time, they’re his family; he thanked them for keeping him safe, he appreciates it. Kevin thanked his wife and his girls, whom he loves, and also thanked his parents, who raised him to be what he is. Everyone applauded. Chief Pritchard asked Lieutenant Zittel to give his final call to Washington County Dispatch, which he did. Washington County Dispatch recognized and thanked him for his 30 years of dedicated service. Dispatch noted Lieutenant Zittel was 10-7 at 1912. Lieutenant Zittel thanked Dispatch for all the years of service, and to all of his brothers and sisters in Washington County, he thanked them for all of their help and recognition, said 10-7, after which everyone applauded. Mayor Bailey asked all of the firefighters, police, and family members present to step forward for photographs, which they did. B. Capture Cottage Grove Photo Contest Winners Staff Recommendation: Receive presentation on the Capture Cottage Grove Winners. City Council Meeting Minutes January 17, 2024 Page 4 Mayor Bailey stated Jaime Mann, Interim Communications Manager and Assistant to the City Administrator, will handle this presentation, after which he will again invite Council to join him in front of the dais for recognition of an individual this evening. Jaime stated we all know Cottage Grove is a beautiful place to live, and it’s full of talented, creative people. For at least a decade, probably more, the City has run a Capture Cottage Grove photo contest where we ask residents to capture images within the city limits of Cottage Grove and submit them for judging. The categories each year change, so this year we had four categories for which people submitted photos: Life in Cottage Grove, Business in Cottage Grove, Cottage Grove Parks & Landmarks, and Cottage Grove Celebrations or Events. We ran the contest for about three weeks; people were able to submit photos with their name and a caption for each photo. After the submission time closed, our City staff voted on all of the photos in each of the four categories. Jaime displayed some of the non-winning submissions to the contest, and said we had 78 photos submitted among the four categories. It was a blind vote for City staff, as no names were on the survey given to staff, it was just the photo along with the caption that the photographer chose. Jaime first displayed the two winning photos, for winners who were not present: Cottage Grove Celebrations or Events: Gwen Martin, for her photo, “Cooling Off with Sparky.” Life in Cottage Grove: Michelle Wind, for her photo, “On Cloud 9.” Jaime noted one photographer, Isaac Pavek, won in two categories: Cottage Grove Parks & Landmarks: For his photo, “Fall Bliss.” Business in Cottage Grove: For his photo, “Tank’s Family Farm.” Jaime stated Isaac is here tonight, so she invited him to step forward to join Mayor Bailey and the Council for the award presentation. Mayor Bailey congratulated Isaac, stated he sees him around town all the time, at all the events, taking pictures, so the fact that he won two of these categories makes perfect sense with the number of pictures that he sees him taking. Mayor Bailey stated these pictures will also tell a story of our community; so, in publications that we’re going to be doing over the next year, we’ll be using your pictures to show some of the exciting things here and the love of our community here in Cottage Grove. Mayor Bailey asked Isaac for the first category, Cottage Grove Parks & Landmarks, where this shot was taken, although he thought he knew; Isaac replied that was taken at Ravine Parkway. Mayor Bailey stated the second category, Business in Cottage Grove, was everybody’s favorite place to get corn, Tank’s Family Farm. Mayor Bailey congratulated Isaac on behalf of all of our staff and everybody in the City of Cottage Grove on winning in these two categories of the Capture Cottage Grove photo contest. Mayor Bailey gave Isaac his two awards, which contained his photos, as well as a check for winning two categories, which will help him buy film. Everyone applauded and photographs were taken of Isaac with the City Council. City Council Meeting Minutes January 17, 2024 Page 5 7. CONSENT AGENDA A.

Mayor Bailey stated Mike Mrosla, Senior Planner, will speak on this Public Hearing topic. Planner Mrosla stated Roers Companies has submitted an application for Site Plan Review, Planned Unit Development (PUD), Preliminary and Final Plats. This site is located at 6850 East Point Douglas Road. Site: The site consists of three Outlots, two lots of record. Shown in blue on the screen are Outlots C and D, the two existing stormwater ponds on site that were constructed for development of this parcel. There is also a pipeline easement that is owned by Flint Hills Resources; there are two crude oil pipelines that pass through there. The Applicant is actively working with them as there are a lot of standards on that pipeline and what can get constructed there. We have two lots of record, Lots 4 and 3, and then Outlot A, which was an Outlot deeded to the City as nondevelopable in 2007 when the Frattalone Southpoint Ridge development was approved. So, Outlot A did not receive any kind of park dedication, as it was deeded to the City as a nondevelopable Outlot. There is also a trail easement along the east side of the property, and that provides access up to Camel’s Hump Park. As part of the application in front of us tonight, the Applicant is proposing to acquire Outlots A, C, and D. The subject site is guided in the Land Use Plan as Mixed Use and is also zoned Mixed Use. However, this wasn’t always the case; the property was previously zoned B-1 with a PDO. Last year, as part of our Citywide Rezoning, we rezoned the property to Mixed Use, to be in conformance with the 2040 Comprehensive Plan. Proposed Preliminary Plat: Is one lot of record, with multiple easements. There is a large drainage utility easement on the left side of the property, then there’s the pipeline City Council Meeting Minutes January 17, 2024 Page 7 easement, and then there’s a gray area shown on the screen that is the development area. There is a trail easement, and then as part of the sale to the Applicant of Outlot A, we are requesting a Deed Restriction be placed on that area, in the northeast corner, to preserve the trees and the trail corridor in that area. So, long term, the trees in that area will stay there as part of this application, and then we’ll be able to go in there and maintain the natural trail corridor that leads up to Camel’s Hump Park. Proposal: 144-unit, mixed-income, apartment building. The proposed density is 37 units per acre with a maximum of 40 units, which is the maximum permitted in a Mixed Use District. The Applicant will provide 29 units at 50% Area Median Income (AMI); just for comparison, 50% AMI in Washington County is an annual income of $43,500 for a single person, or for a family of four, $62,100. The Applicant is also setting aside 8 units at 60% AMI, which is $52,200 for an individual or $74,940 for a family of four. All of the rents are set by HUD: The minimum rental price for 50% AMI is $1,087; for 60% AMI, the rent is $1,398. The 107 remaining units will be set at market rate or below; the Applicant has indicated that they’re proposing to have rents slightly below what the existing multifamily complexes in the community are, so, that will allow for incomes of 70% to 100% AMI to potentially live in the proposed project. Amenities: Some amenities that will be included in the project interior are a game room, community room, and a fitness room. The proposed building is shaped like a U, and that was done on purpose, to keep the amenities away from the existing uses on East Point Douglas Road. So, the active area will be included in the courtyard area, which will also have a number of amenities, including a firepit, a patio and dining area, recreational lawn, a playground/tot lot, dog wash, and dog run. PUD Flexibility: Due to site constraints previously discussed, PUD flexibility has been requested. However, in exchange for the PUD, we’d like to see some of the City’s Comprehensive Plan goals met, and this application in front of us tonight is meeting a lot of those goals for affordable housing. It will provide additional housing options on this side of the community. So, the Applicant is requesting flexibility for building height, architectural materials, parking ratio, and landscape flexibility. Otherwise, the proposal is consistent with the Zoning Code except for building height. Proposed Parking: City Code requires 230 stalls, or 1.6 stalls per unit. The Applicant is proposing 216 stalls, or 1.5 stalls per unit. There are 82 surface parking stalls, and 134 garage parking stalls. The garage is in two levels. The first level is below grade and is accessed off of the drive off of East Point Douglas Road; the second one is accessed internally, through the parking lot, and that will be like the main level of the building, as you can see on the images on the left-hand side. There’s an internal pedestrian system that connects to the existing sidewalk on East Point Douglas Road. As part of the project, the Applicant is proposing to put in a six- foot-wide sidewalk along the eastern side of the property that will connect to the proposed relocation of the existing natural trail on the northeastern section of the property, as shown in green on the map. You can also see on the image on the screen where all of those trees are being preserved as part of that Deed Restriction. Proposed Architecture: Multifamily buildings are required to have 65% Class 1 materials, which include glass, stone, and brick. The Applicant is proposing to use 47% and includes glass and stone. That 47% is pretty common; we’ve seen it on the City Council Meeting Minutes January 17, 2024 Page 8 developments on Hardwood Avenue, Aurilla, for example, The View apartments, and the recently-approved Trellis, as all of those are at about 47% Class 1 materials. Last year, Council had a meeting with the Applicant to talk about the proposal, and at that meeting, Council wished to make this building as a gateway feature into the community, as it’s highly visible from Highway 61 as you come into Cottage Grove. The Applicant heard that concern and modified the building to include a lot more stone columns to kind of make it pop as you drive into the community to create that gateway feature and kind of set the architectural tone for the community. Again, the proposal is 47% Class 1 materials; there are also Class 2 and 3 materials, 14% of the building is specialty block and 39% is fiber cement. Again, the Applicant is asking for some flexibility in the building height; this building will be built into the hillside, similar to The Legends of Cottage Grove. The overall height on the Highway 61 side of the building is 67 feet; however, if you go to the side not adjacent to Highway 61, that side is up to 55 feet. So, that 67 feet is comparable to the height of The Legends building that exists on East Point Douglas, as the height of The Legends on the Highway 61 side is 73 feet of grade to the peak of the roof. So, this building is similar in height to The Legends. Landscaping: The Applicant is asking for some flexibility due to the site constraints and stormwater requirements. Applicant is proposing to plant 53 trees, where ordinance requires 85; however, the Applicant is looking to plant additional trees on site to get that number higher. They are planting significantly more shrubs, as ordinance requires 94, and the Applicant is planting 408; the majority of those shrubs are around the perimeter of the parking lot, in the parking lot islands, and on the base of the building, as required by City Code. No tree mitigation is required; the two images on the bottom of the screen show the site when it was prepared in 2003 and 2008. A lot of the trees that the Applicant is proposing to remove are volunteer trees that have grown since the site has been cleared. Again, the removal does not trigger tree mitigation. You can see on the 2003 image is that wooded area that will also be preserved. Site Access: As part of all the development on Hardwood Avenue, the City hired Bolton & Menk to complete a traffic study. In recent years, we’ve seen the development of the Aurilla Apartments, The View, Pizza Ranch. So, to ensure that Hardwood Avenue can handle additional trips, a traffic study was completed. Once we received this application, we asked Bolton & Menk to amend their traffic study to include this proposal. The Applicant also completed a traffic study just to make sure that East Point Douglas Road and Hardwood Avenue can handle additional trips. Both studies said that the streets are designed appropriately to handle additional trips; the design capacity of East Point Douglas Road is approximately 2,000-5,000 trips per day. With the proposed addition of the project in front of us tonight, that would bring the total trips up to 1,750. Also, our Public Works Director, Ryan Burfeind, is here, so, if you have any additional questions on that, he’ll be happy to talk more about that. Public Process: The Applicant held a Neighborhood Meeting on November 14, 2023, at The Legends of Cottage Grove, and 33 residents attended. General questions raised were about why the Applicant had selected this site, construction timing, anticipated rents, traffic noise from Highway 61, and noise from the potential increase of traffic on East Point Douglas Road. The main talking point was the increased traffic on East Point City Council Meeting Minutes January 17, 2024 Page 9 Douglas Road; as previously mentioned, the traffic studies said the roads were designed to accommodate that traffic. Notices of the Public Hearing were posted in the Pioneer Press and were also mailed to property owners within 500 feet. Staff did not receive any comments during that time. Also, no one participated in the Public Hearing at the Planning Commission on December 18. At that meeting, the Planning Commission reviewed this, held the Public Hearing, and they voted unanimously to approve the project before you tonight. Request for Financial Assistance: Planner Mrosla stated this project includes a request for financial assistance. Gretchen Larson, our Economic Development Director, will speak about that. Director Larson stated as a part of this process, all of the required Public Hearing Notices required by law have been completed. Tonight is the opportunity for the City Council to hold a Public Hearing for the modification to the development program for your Development District No. 1, and to establish a Tax Increment Financing (TIF) District No. 1-21, which would be Roers, a housing district. As a part of the process, in October the City received a request for public financial assistance from the developer. The Council received information on the project from the developer, also in October. As a part of that discussion, they said what they wanted to construct, which Mike has presented tonight, is a mixed-income, multifamily apartment project, with 20% of the units at AMI. Based upon the desire of the City Council to have even more affordability into the project, Roers went back to the drawing board and included 8 more units at 60% AMI and some more naturally occurring affordable units at 70% AMI and 80% AMI. The City’s financial consultants, Ehlers, then conducted a second analysis, and they concluded that with the additional affordability, that assistance for up to 15 years and $1.96 million in today’s value was warranted. On January 9, 2024, your Economic Development Authority (EDA) approved the project plan and the proposed modification to Development District No.1, to establish Development District No. 1-21, which is Roers. To complete the process, we again have to hold a Public Hearing. There is also a Development Contract in your packet, and that Development Agreement is required; it’s an agreement between the EDA and the developer, and it defines all the requirements for the actual project itself and everything that the developer has to meet in order to receive public assistance. It also includes a lookback provision, as projects of this size have some adjustments to them over time when they get off the ground, so that has also been done by your financial advisors. While the City is not a party to the actual Development Agreement, your EDA bylaws and enabling resolutions require you to approve all of the projects undertaken by the EDA. Recommendation: Director Larson stated there’s a recommendation slide before you, and staff would like to note that the first three recommendations should be taken first, considered by you at each individual motion, before you hold the Public Hearing. We’ll be happy to answer any questions. The other two recommendations will be taken after the Public Hearing is closed, when you can consider those items as well. Mayor Bailey asked if Council had any questions for Planner Mrosla or Director Larson. City Council Meeting Minutes January 17, 2024 Page 10 Council Member Olsen thanked Planner Mrosla and Director Larson for presenting this to us. He also saw the presentation at the EDA Meeting last week. He asked Ehlers to answer his question because they’ve answered it once before, and he thinks it’s good information for the public to have. It has to do with the lookback provisions that are included within the TIF Agreement, why those exist, and how they safeguard or protect the EDA and/or City in circumstances like this. They’re not uncommon, lookback provisions are often there, but it’s one of those things that we don’t talk about very often. He thinks it’s worth articulating to the public, watching at home or who may be watching it later, what those provisions are and why they’re there. Schane Rudlang, with Ehlers, gave a quick review of the lookback provisions in this project, which are typical for projects like this. In this project, there are three different types of lookbacks, which are again kind of the standard that we at Ehlers recommend cities do: 1) The first is a lookback when the project is completed. So, you’re considering dedicating money to the project tonight, just under $2 million. It’s based on an analysis that the project is going to cost a certain amount of money. If, for some reason, the costs go down for the project, and the developer builds it a lot cheaper than they had anticipated and had shared with us and Council, then the subsidy that was analyzed to be needed now maybe isn’t needed. So, there would be a cost adjustment during the Certificate of Occupancy, when the project is done and getting ready to be occupied. 2) The second lookback is a performance lookback, to look back at stabilization of the project. So, roughly a year or so after the project is opened and they have all their leases in, they’re 90-or-95% occupied, we know what the rents for the project are going to be. Again, the analysis and the level of subsidy was set based on the best information that we have today; we know a lot about what the market is right now, but in two years, when the project’s open and leased, maybe rents are doing really well. That means maybe there was too much subsidy in the project, and so, we do an analysis at that point, and then adjust that subsidy down if that’s the case. If rents are exactly what we or the developer had as Pro Forma today, there’s no adjustment. If they’re lower, if the project isn’t doing as well as we had expected, we also don’t adjust it then. So, the developers always say we should adjust it higher at that point, but we don’t do that. 3) Similar to the performance lookback, it’s a lookback in the event of sale. So, they sell the project, there’s an actual sale, and we go back and adjust the TIF Note at that point if the project is performing a lot better than it was originally anticipated to do. He said generally lookbacks don’t result in an adjustment because projects generally cost more than what we’re looking at today, and rents are usually within a range that we’re analyzing right now. So, it’s relatively rare that there are adjustments, but they do happen; they’re a great safeguard to make sure that the TIF assistance is the right size. Council Member Olsen stated he really thinks that’s a key point. He appreciated him stepping up to the podium and sharing that. It’s important for the public to understand that when we work with developers as a City Council or as a community, many times we City Council Meeting Minutes January 17, 2024 Page 11 utilize tools like TIF in order to get projects off the ground, and then we recapture that TIF revenue later on after the project is up and running. Ensuring that we right size the TIF is hard to do because market conditions change all the time. He thinks we can all agree that we’ve seen interest rates go up lately, over the last 1.5 years or so, and now there are some predictions out there that those will start to drop. So, these lookback provisions give us a safeguard against that. He just thinks that’s smart business, but he also thinks it’s something that very few people know that we do; so, that’s why he asked him to share that with us again. He very much appreciated his time and thanked him. Mayor Bailey asked if the Applicant wished to share anything. Travis Fauchald with Roers Companies thanked City staff for their presentation. Over the past couple of months, we’ve been working to get this project and its design to a spot that we can present for approval. If approved, we will continue working with the gas pipeline company, as Mike mentioned, to make sure all the formal written approvals are there, to make sure we’re building a project that works for them, and they have an easement that governs a majority of the site. We will continue working on our architecture and civil plans to resubmit for permits, and then we would begin financing the project, preparing to start construction later this summer. We’re really excited to be here and to be a partner in the investment community. Our engineers and our architects are also here if there are any questions on the design or any of the nitty-gritty details that he might not be able to answer. If there are any questions, he, Logan, and Pete are all here. Council Member Khambata thanked them for taking the time to be here tonight. For anyone who might be here or watching at home, who isn’t familiar with the term AMI, Area Median Income, he asked Travis to briefly explain how you determine those levels and how they’re regulated. And, moving forward, how those rents stay affordable. Travis stated as a large multifamily developer that does a lot of work in the Twin Cities, we do some market rate communities, workforce communities, and a lot of our work are affordable communities that are rent and income restricted. As Mike mentioned, those rent and income restrictions are laid out in a Declaration of Land Use Restricted Covenant, a document that will run with the land that will govern the use and the income and rent restrictions. What that means is ultimately only certain people are able to live in these units with discounted rents. What our property management and our compliance departments do is make sure we’re renting to the right residents, that they are getting cheap rent, and they are making what they say they make, to ensure the TIF is being used to serve the right people. Ultimately, the rents and income restrictions are published by HUD, depending on the AMI of the county; those are revisited each year. So, if rents go up in Washington County, the rents and the incomes would go up by the corresponding amount. If rents were to go down, the rent and income restrictions would move or stay the same. So, we’re not able to say we’re going to provide affordable housing and provide X amount of units at X income restriction and then change those later down the road. It is a math equation that ultimately determines what those rents are and who can live there. On this project, we have rent and income restrictions on one-, two-, and three-bedrooms; we anticipate our tenants are going to be service City Council Meeting Minutes January 17, 2024 Page 12 workers, teachers, people living on a fixed income, single parents. Those are the residents that we see on these projects. He’s hopeful that answers his question. Council Member Khambata stated absolutely, thank you. Mayor Bailey thanked Travis for coming in again tonight and listening to the Council when we had an earlier session about wanting to spruce up the building a bit, just from a visual standpoint. That is a very unique parcel. Other developers have tried to come in and figure out how they were going to make it all work, but they never got to the level where you’re at now, saying you have a project you believe is going to move forward. He thinks it will be a great use of that property. It will be pretty amazing whether you want to walk down East Point Douglas, around to the different retail options, or go up the hill to Camel’s Hump Park, you’ve got a unique piece of property there that he thinks will be a gem for those who want to live in that particular area of Cottage Grove. Mayor Bailey stated one of the big things we heard from residents at The Legends, etc. wasn’t so much the project that’s coming in, but they were concerned about traffic. He stated once this project comes in, everything’s great as we obviously expect, and let’s say the traffic becomes a bit of an issue, maybe it’s the speed. He asked staff what would be the steps we could take if we were to start getting some concerned citizens down there, saying it’s been tough for them to cross the road or cars are speeding. He knows what some of the answers are, but thought it would be good for the public to hear some of those answers. Director Burfeind stated as discussed earlier on, that area continues to be monitored. Thinking about Hardwood Avenue and then Hardwood Court, that intersection is one project we are specifically working on, with signal plans there; so, that’s definitely something that’s in motion. It’s always hard along that entire corridor, and we want to meet warrants for any type of signal improvement; it’s very important that we monitor that very closely. We look at all of those intersections along that area, including East Point Douglas Road and Harkness Avenue as well, but Hardwood Court and Hardwood Avenue is our next focus for this area. The signal is being worked on, and we really are looking at how is the development going to happen; we don’t quite meet warrants now, but there are other challenges in this corridor with sight-line issues. Of course, we kind of have the curves going up and over the hill, so that kind of plays into it, where we could actually look at building a signal, taking that into consideration. It’s not just the traffic, but the sight lines as well. Mayor Bailey stated if that day were to come and people have concerns, they can obviously reach out to one of us on the Council, Public Safety, and City staff. If there are challenges or issues at some point, we always go back and take a look at it and add features or things to maybe slow down the traffic, or increase patrols, or whatever needs to happen there. He just knows that with all the senior facilities in that market there, they love to walk. Every time he goes down there, they’re always walking along the bluff there of Camel’s Hump. He thinks maybe there’s a perception that it’s going to be an issue, maybe it won’t be, and hopefully it won’t be anything. If there is, there is a way to react to it. Director Burfeind agreed. City Council Meeting Minutes January 17, 2024 Page 13 Council Member Khambata stated as he had said at Roers’ initial presentation, back in October, getting to 60% AMI is a tough task; especially with this parcel and the unique constraints that it presented, he thinks Roers came to us with a really well-thought-out plan. They tackled all of the practical difficulties that the property presented in their first shot, and they’ve only improved upon it. So, for his 20%, he’s really in favor of this project. Motion by Council Member Thiede to Adopt Resolution 2024-005 approving the Purchase Agreement for Outlots A, C, and D to Roers Cottage Grove Apartments, LLC; second by Council Member Olsen. Motion carried: 4-0. Motion by Council Member Khambata to Adopt Resolution 2024-006 approving the Preliminary Plat and Final Plat for Camel’s Hump Addition; second by Council Member Thiede. Motion carried: 4-0. Motion by Council Member Olsen to Adopt Resolution 2024-007 approving the Planned Unit Development and Site Plan Review for a 144-unit, six-story, mixed-income, multi- family apartment building located at 6850 East Point Douglas Road South; second by Council Member Khambata. Motion carried: 4-0. Mayor Bailey opened the Public Hearing, an opportunity for anyone who wants to speak on the modification to the Development Program for Development District No. 1 to include the establishment of Tax Increment Financing District No. 1-21 (Roers). Bonnie Matter, 6649 Inskip Avenue South, stated she had questions. Her concerns are the traffic, and it’s more about the Pizza Ranch and Kohl’s. What she doesn’t understand is if there’s more than one way to get out of that place; is there only one road? Mayor Bailey replied where this is going, yes, there is only one road. Bonnie stated one road; so, is that okay? She thought you had to have two ways to get out. Mayor Bailey stated he thinks that’s a question for Director Burfeind or Director Koerner. He thought what she was referring to is the reason we’ve added a second road over in the Industrial Park. Ms. Matter stated right, in another area, but yes; Mayor Bailey stated that’s a good question, we’ll respond to that. Ms. Matter also asked on the $1.9 million, is that bonded, are you going to bond for that now? Mayor Bailey asked Director Burfeind if he wanted to take the first question and asked Director Larson if she or Ehlers would take the second. Director Burfeind stated that’s correct, that we do look for two points of access, it is really specific to emergency vehicle access. We want that for all users; obviously, in this area, it’s very challenging as its got the bluff and the highway. For emergency vehicle access, there is actually a second way to get through, actually off the ramp as there’s a gate in the Highway 61 fence. If there was an issue with the road itself, maybe down by Tutor Time, there’s actually a different way to get vehicles in and out of that area City Council Meeting Minutes January 17, 2024 Page 14 through the accessing that was put in back in 2007, he believed, with the original development. Mayor Bailey stated this was a good question that Bonnie asked, as, for example, up by Hinton Heights, he knows there’s a gate on the back side of Hinton Heights, with only one place going in and out. The purpose of that gate is they didn’t want traffic to go through there, but we have the gate there in case Public Safety needs to get access. This is kind of the same situation, only the gate in this case is, in essence, along Highway 61. Director Burfeind stated that’s correct, it’s on the ramp, specifically. Director Larson stated she would have Schane from Ehlers answer the question about the TIF. Schane stated the short answer to the question is no, the City is not bonding or the EDA bonding for those funds; it’s called a Pay-As-You-Go note, meaning the property owner pays the property taxes, and the portion that is TIF is then dedicated to the project but only if that money is there. So, there’s no financial risk to the City because of the arrangement; they’re not bonding, they’re not borrowing for it. He hopes that answers her question. As no one else wished to speak on this item, Mayor Bailey closed the Public Hearing.

COUNCIL COMMENTS AND REQUESTS Council Member Khambata thanked Public Works for getting out in the bitter cold and doing what little snow removal they had to do. After last year, he hopes we can keep it light, figuratively and literally, the less snow the better. City Council Meeting Minutes January 17, 2024 Page 15 Council Member Olsen stated he read a report this week that he found very interesting. It had to do with the reason behind developers working more closely with communities like ours on kind of family-oriented apartments, whether that’s market rate or AMI, just like the one that we talked about. The report was written by an analyst at Citibank; of course, Citibank is one of the largest banks in the world, they do a lot of financing for these projects. What the report essentially told us is that if you look at 1991 to 2023, the price of owning a single-family home has gone up about 80% in that timeline; whereas, the price of apartment rental has gone up about 40%. So, there’s quite a gap between renting and owning. He knows that it’s not that simple, there are a lot of other benefits to home ownership from a tax write-off perspective. But it helped to explain a little bit, for people who have been asking why is the City of Cottage Grove becoming such an attractive place for developers, who are looking to put more density and/or apartments as part of their developments. Frankly, it boils down to what is the market going to bear and what does the end user have the ability to afford. He thinks this project with Roers is just a small example of what we’ve been doing over the last several years with regard to trying to respond to varying market conditions, to make sure that we have lifecycle housing for the people who want to live in our community. He's very grateful for staff, and for all the various developers that staff’s been working with, that they’ve been bringing those kinds of projects our way. It definitely is necessary from an affordability perspective. Council Member Olsen mentioned that tonight we had the honor of showing our appreciation to a 30-year veteran of the Cottage Grove Fire Department, Kevin Zittel. In February, at our second meeting, he will be presenting a check from his wife and himself to the Cottage Grove Public Safety Board as part of our annual donation to the Craig Woolery Scholarship Fund. Last night, our Cottage Grove Lions Club was kind enough to make a $2,000 donation to the Craig Woolery Scholarship Fund; last year, they donated $1,500, so, they kicked it up a notch. Every little bit helps, it’s very much appreciated, that check is now in the hands of our Public Safety Director. If there are people out there who are interested in learning more about the Craig Woolery Scholarship for first responders, why it exists, how you apply, etc., he would suggest that you reach out to any of the Public Safety Board members, particularly, President Julie Rice. You can also reach out to our Public Safety Director, to me, the Mayor, or City staff. But there’s an opportunity here to really support our Public Safety folks in a way that they need, which is to help them pay for their education, so that we can get the next Kevin Zittel, or maybe more, on our Fire Department or our Police Department. We definitely have to have great Public Safety personnel in our community, serving our residents every day; losing somebody like Kevin is a big loss, 30 years of experience, knowledge, etc. that he could pass on down to other firefighters, other EMTs, other medics. That’s a lot to lose, and we’ve lost some more over the course of the last year. So, we want to refill those ranks, and the Craig Woolery Scholarship is a really great way to help those people pay for school. If you’re interested in learning more, reach out to us; on February 21, there will be a check presentation here at the City Council towards that Craig Woolery Scholarship. Anybody who wants to donate, the Public City Council Meeting Minutes January 17, 2024 Page 16 Safety Board would be happy to take whatever funds you felt were appropriate towards that goal. Mayor Bailey stated he’ll piggyback on something Council Member Olsen mentioned; earlier this month, the Council had a Strategic Planning workshop at our new Glacial Valley Park building, which is absolutely gorgeous. We’ll eventually be having a ribbon cutting and grand opening for the public. There is a specific wall in there that was painted by an artist to share the thoughts behind the purpose of Glacial Valley Park and the theme, both past and present. One of the things that we discussed and staff is going to be working on is a housing study. It kind of alludes to the fact that we’ve been working with a number of different developers on the different types of housing that we need to look for, going forward, as the population is changing. People are getting older and there are different types of housing that people want now, maybe that are different than what he wanted or his parents wanted growing up. So, we need to understand what that means within our community. So, he’s very excited to see what that housing study that we do comes back to tell us about the community with the great developments and things happening. Mayor Bailey also mentioned that earlier this evening, we had the opportunity to sit down with our legislative contingent, along with our Washington County Commissioner, to go over what he’ll say are our goals and objectives for the upcoming legislative sessions, specifically, for the State. We went over quite a few different things that are very important to the City of Cottage Grove. We also had a Bonding Tour here yesterday with the State Senate. About 1.5 months ago, we had met with the House in another part of Washington County, and he presented to try to ascertain some funds for the 100th Street road project. We have some funds that we’ve already received for this road project, it’s an over $40 million project. We’re working all the different angles to help get that road project, trail project completed, or at least paid for; our ask from the State was $12.5 million to see if they can help us bridge the gap to hopefully finish getting all the funding for that. He thanked our legislative team, as they did a great job with us today in commenting and listening to what our goals and objectives are; that included talking to, or providing a letter to, the DNR to help us get that money that’s supposed to be going to purchase park land, next to the Dunes Scientific and Natural Area (SNA). We can hopefully get them to get that done because we do want to see that part of the Dunes SNA. Mayor Bailey stated he’s on the Transportation Advisory Board (TAB). TAB basically works with the Metropolitan Council, the governor, etc. to provide funding sources for money that flows in from the Federal government, etc. into the State of Minnesota; they try to divvy out that money in a fair and equitable manner. In the next group of projects, as he told our staff and legislative team, there are over 150 projects that have been submitted for financing; the money available is about $250 million. If you added up all of the projects that were submitted, they total over $850 million. Once again, we came off of a pretty big legislative year where a lot of money was provided to cities and it still is, through different means, for transportation projects, parks, etc. There’s still a great need City Council Meeting Minutes January 17, 2024 Page 17 out there. When we talk about maybe going after additional funding for 100th Street, or other projects within the City, we’ll continue to do that; we’ll continue to fight for the citizens of Cottage Grove to hopefully get our share of that funding. Mayor Bailey stated he appreciated our Public Works Director, Ryan Burfeind, and our staff. Yesterday, the PCA issued new health-based limits for PFCs, which the citizens of Cottage Grove have dealt with for many years. Earlier today, Ryan put out a video about that. Due to the great work of our team here at the City staff level and some of the government agencies with whom we deal, if people in Cottage Grove are worried about their water, they should not be. Our water is clean, we treat all of our water here in Cottage Grove, down to, as Ryan calls it, a “non-detect level.” A lot of communities out there are going to be grappling with how to pay for this stuff, whereas the City of Cottage Grove is lucky enough that we qualified for the original Consent Decree by 3M but also the Settlement Agreement. Our first permanent Water Treatment Facility is under construction as we speak, with a second one that will be coming in the next couple years. In no case will any of our residents have to worry about their drinking water. So, if you hear that out in the public, as this information cycles through, rest assured in Cottage Grove, our staff has our back, and our water is clean. He’s 100% confident in the abilities of drinking safe water here in Cottage Grove. 13. WORKSHOPS - OPEN TO PUBLIC - None. 14. WORKSHOPS - CLOSED TO PUBLIC - None. 15.

Planning Commission Minutes 2023-12-18 City of Cottage Grove Planning Commission December 18, 2023 The Regular Meeting of the Planning Commission was held at Cottage Grove City Hall, 12800 Ravine Parkway South, Cottage Grove, Minnesota, on Monday, December 18, 2023, in the Council Chamber and telecast on Local Government Cable Channel 16. Call to Order Chair Frazier called the Planning Commission meeting to order at 7:00 p.m. Roll Call Members Present: Pradeep Bhat, Ken Brittain, Jessica Fisher, Evan Frazier, Eric Knable, Derek Rasmussen, Emily Stephens Members Absent: None Staff Present: Emily Schmitz, Community Development Director; Mike Mrosla, Senior Planner; Conner Jakes, Associate Planner; Amanda Meyer, City Engineer; Crystal Raleigh, Project Engineer; Tony Khambata, City Council Liaison Approval of Agenda Rasmussen made a motion to approve the agenda. Fisher seconded. The motion was approved unanimously (7-to-0 vote). Open Forum Frazier opened the Open Forum and asked if anyone wished to address the Planning Commission on any non-agenda item. No one spoke. Frazier closed the Open Forum. Chair’s Explanation of the Public Hearing Process Frazier explained the purpose of the Planning Commission, which serves in an advisory capacity to the City Council, and that the City Council makes all final decisions. In addition, he explained the process of conducting a public hearing and requested that any person wishing to speak should go to the microphone and state their full name and address for the public record. Public Hearings and Applications 6.1 Lumbermen’s Outdoor Storage – Case CUP2023-021 Lumbermen’s, Inc., with approval from NorthPoint Development, has applied for a Condi- tional Use Permit to allow for the outdoor storage of materials incidental to the principal use at 7601 100th Street South. The materials will be fully screened by a 6 -foot tall privacy fence that will enclose 25,000 square feet of the southwest parking area to be used for material storage. Planning Commission Minutes – Regular Meeting December 18, 2023 Page 2 of 9 Jakes summarized the staff report and recommended approval subject to the conditions stipu - lated in the staff report. Rasmussen said we got an email referencing a five-story building; he asked is there any new planned development to the immediate south or something. He’s not sure what they were talking about, what’s visible from this five-story building. Jakes replied that email was referring to the Norhart development, a five-story apartment building to the west of the building site. This was something that was discussed through the development application, thinking about site lines. The industrial development and outdoor storage, if approved, would already be in place prior to tenants moving into that building. So, they would be aware of onsite activities prior to renting the units. As part of NorthPoint’s original approvals, they submitted a detailed landscape plan and they’ve planted numerous trees on the western property line. Other trees have the potential to be removed as part of the Norhart project, but as these trees mature it’s staff’s understanding that those would also screen. Frazier stated if the applicant has anything to add, they can step to the podium. Tom Hysong stated he’s the Operations/Transportation Manager for this location. He stated they’re based in West Michigan, we sell building supplies, and we’re very excited to be moving into this market, as it’s a new market for them, and they’re excited for the opportunities here. Fisher asked, you’re leasing this space; when and if you ever decide to not lease anymore, would you take the fence down and take it with you. Ryan Zickel, Development Manager, North- Point Development, 3315 North Oak Trafficway, Kansas City, Missouri, replied typically through our re-leasing process, hopefully we push for the renewal and get them to stay for 20 years. In the off chance that they don’t, that will be considered as a re-leasing opportunity, which increases marketability to future tenants. We will potentially remove it, just depending on market conditions at that time. Fisher asked staff if somebody else takes it over, would another Conditional Use Permit (CUP) have to be issued for the use of that storage area. Jakes replied the CUP runs with that land, so that would allow for that storage area. However, he noted in the conditions of approval, there is a condition that states if that storage area isn’t utilized for more than 12 months, upon written notification of the City, we could require that fence to be removed. Bhat asked what would happen if it wasn’t used and the fence was removed, would it go back to being a parking lot or what would be the status of that area. Zickel stated that’s correct, it would just go back to being a standard parking lot. Any holes that would be left from fenceposts would be filled, asphalt repair would be completed, and it would be in like -new condition so that we could re-lease it. Rasmussen stated he’s curious with the large pallets of material that you’re getting in there, how do you get them in there with two eight-foot gates. Hysong replied if the gate’s like this, we take the forklift and swing the pallets in, or we lift them and just go up and over the top of the fence; the forklifts will go higher than the fence. Frazier stated that might have answered one of his questions. The letter we referenced talked about maybe a covered storage area. He’s assuming one of their concerns would be being able to get the forklifts in there then, if they go over, but he asked if there were other concerns about Planning Commission Minutes – Regular Meeting December 18, 2023 Page 3 of 9 if it was going to be required to be a covered storage area, from your point of view. Hysong replied he didn’t think so. Fisher asked with the building that it is in, are there walls already kind of sectioning off each space, as this one has three separate spaces. Zickel stated absolutely, that’s a great question. Fisher asked, so, there was a wall already there; Zickel replied it’s currently being built in place, within the building. Fisher stated her only thought, when she was reading through this, was that seems like a really large outdoor storage space. So, why would somebody just not lease more of the building, but if there’s already a wall constructed in there, then that answers that question. Zickel stated that wall kind of lines up on the previous plan with the edge of the outdoor storage to maximize the space that they can use. Frazier opened the public hearing. No one spoke. Frazier closed the public hearing. Frazier stated he had another question. Two of the requirements that we look for in a CUP are that the use won’t be detrimental to the public comfort and that it won’t impair the enjoyment of nearby property or diminish values within the neighborhood. So, with a concern noted in an email that’s going to be made part of the record of this, a resident was concerned about people having an apartment that’s facing this open storage area. How do we kind of weigh that, then, as part of diminishing the use or enjoyment of a nearby property. Jakes replied when we talk about the full picture of enjoyment, part of that relates to noise, and there are noise standards in place. It is an industrial use, so there would be trailer parking. Weighing that vs. outdoor storage is somewhat similar, they’re still storing, whether it’s trailers vs. materials on site. It doesn’t necessarily change how we refer to the CUP, taking that into account; he noted that generally we have an industrial site and then we stage down through resi dential Zoning Districts. He would say it’s something quite standard where we have an R-6 butting up to an industrial use, throughout the City, in the past. Rasmussen asked previous to this fence, where its currently going is currently designated and approved for tractor-trailer parking, correct. Jakes replied, yes, that’s correct. Frazier stated he has some concerns, especially with the resident pointing out that this is going to be right next to an apartment complex, where presumably some of these apartments will overlook the storage area. He thought it was a good point that Rasmussen made that if it wasn’t going to be a storage area, it would be tractor-trailer parking. So, what’s the difference between those two uses; in his point of view a CUP would be appropriate for outdoor storage at this time. Fisher asked do we know if this apartment building is actually being constructed because it would not be shocking to see an application come through and it never comes to fruition. So, here we are trying to decide a hypothetical person renting a hypothetic al apartment in a hypo- thetical building that’s not yet been built. Here we have people who are following the law and asking a reasonable ask. She feels considering all the hypotheticals, it seems a little strange to her. Schmitz stated the Norhart project has its approvals; they are still working to continue to move forward, so we very well might see that construction happening in 2024. Regardless, the site is zoned R-6 for that high density; so whether or not it’s the Norhart project, of course we would hope that another project comes to fruition and would be that same density. Fisher stated right, and she’s not implying that she doesn’t want the apartments there, that’s not what she’s saying. She’s just saying that that’s in the future, and who know what will actually start happen- Planning Commission Minutes – Regular Meeting December 18, 2023 Page 4 of 9 ing there. She stated, personally, she’d rather look at shingles than a bunch of trucks, but that’s just her thought. Fisher made a motion to approve the Conditional Use Permit subject to the conditions stipulated in the staff report. Rasmussen seconded. Motion passed unanimously (7-to-0 vote). 6.2 Roers Companies Apartments – Case PP2023-020, SP2023-020, PUD2023-020 Roers Companies has applied for a Site Plan Review, Planned Unit Development (PUD), and Preliminary Plat for a proposed 144-unit mixed-income apartment building to be located at 6850 East Point Douglas Road. Mrosla summarized the staff report and recommended approval subject to the conditions stip - ulated in the staff report. He asked Assistant City Engineer, Crystal Raleigh, to speak further about traffic, a major talking point at the Neighborhood Meeting; she spoke about the site access and traffic study. Fisher said Raleigh mentioned that the intersection didn’t warrant a change; she asked what is the threshold and what would warrant a change there. We’ve had discussions about that par - ticular spot, and O2B Kids is theoretically going in there; that intersection is not a nice spot and wondered when it would be addressed. Raleigh stated there are many different factors that contribute to those intersection warrants, such as traffic volumes, but also sight distance and elements like that. We took the O2B Kids’ traffic study, which was a significant study for that intersection, which had incorporated a multifamily development on this parcel. The development that’s being proposed is a bit bigger, so we had an addendum to the traffic study from the O2B Kids; even with the additional traffic that’s generated by this development, those various war - rants still were not met. Fisher asked what the warrants are, though, what are the thresholds; is it close, is it like a hair under. To her, that’s the biggest thing she’s worried about; obviously, that road can handle it, but with that little bitty intersection, she already thinks that road is a little bit of a nightmare. She doesn’t know if she’s the only one who thinks that, but that’s her biggest concern with it. She doesn’t know if anyone can answer that question, what the threshold is. Meyer stated there’s a variety of criteria that needs to be evaluated, whether or not an all -way stop is considered. If it would be warranted for a signal, we could do an all-way stop as a temporary measure. There are other things revolving around five or more crashes reported in a 12-month period, susceptible to correction by an all-way stop. There are also items related to vehicular volume, so, the number of vehicles per hour in an eight-hour timeframe. It’s also about the speed, the approach speed of vehicles; if traffic is exceeding 40 MPH for the 85th percentile, so the majority of traffic exceeding a specific speed limit approaching an intersection. There are four different criteria that we would analyze; it’s really about the number of vehicles within a specific timeframe, definitely the crashes, and just if speeds are increasing and really having to evaluate that intersection from a safety perspective. Meyer stated unfortunately it’s not a black- and-white answer. Brittain asked about the pipeline easement. Is the parking lot over the pipeline easement; if so, how does that work. Is it because its not necessarily building a permanent structure, that they can dig it up if they need to; how does that play into things. Mrosla replied that is exactly correct. There is absolutely no build within that easement, that’s clear. They cannot go past this line, so they cannot build, but they can build a parking lot in there. However, the biggest thing that the Planning Commission Minutes – Regular Meeting December 18, 2023 Page 5 of 9 applicant is working with them on is grading in there. The pipeline owner wants a specific depth between the pipeline and the surface; so, the applicant is working closely with them on that. With conversations he’s had with the applicant, the primary area that they’re working on with the pipeline owner is circled on the screen; that’s the area where they’re trying to get that depth to the right area. Brittain asked if that depth is intended to be such that the weight of the car traffic and parking, etc. doesn’t interfere with the pipeline’s operation or determine feasibility. Mrosla replied no, the depth is for maintenance; they want to make sure they have easy access for maintenance. They don’t want to dig too deep so if something happens, they can get in t here and resolve the matter quickly. It’s worth noting, too, that there is going to be a permanent easement in here to allow for access into that site. Also, they can access off of Highway 61 if there ever comes a time they have to access the pipeline. The applicant has been working really closely with the pipeline on this because it kind of hinges on that; so far, they have identified Flint Hills’ support of it, however, they’re still working on some minor aspects of that. Stephens stated it said due to site constraints, the applicant is unable to plant the required amount of trees in a practical way. However, they’re proposing to plant over 400 shrubs ; she thinks everybody knows that trees have different benefits than shrubs. What are the site con - straints, and what happens when they cannot meet the tree requirement. Mrosla replied part of the constraints on site is the pipeline easement itself. They don’t want roots going into that. He won’t be shocked as the planning gets to the process that the number of trees near the parking lot will probably be removed, as he can imagine they will not want those going in that area. So, he can see modifications there. The shrubs go lower into the soil; however, he’s not a landscape architect. He doesn’t know if the applicant is able to address that a little bit better. He asked the applicant to address the landscaping, on why some of the plantings are proposed in the areas on the plan. Stephens stated let’s say they aren’t able to meet th e requirements; didn’t we re- cently update our Code that they have to pay some sort of fee so we can plant the trees else - where. Mrosla stated that’s something he has discussed with the applicant. If they’re unable to plant those trees on site, they have brought up the possibility if there is a fund they can pay into in order to meet that number. That’s something we’re working on. As a condition of approval, we require seeing a final landscaping plan prior to the issuance of a building permit; however, the applicant realizes that is a standard, we addressed that with him, that we like to see that number come up. However, we understand the site constraints with the pipeline. Mrosla stated he'd let the applicant talk more about where they are in revising the plan. Frazier stated he made a note of the applicant speaking, but before we get to that, we’ll finish questions from the commissioners. Fisher stated back to the parking lot, let’s say that Flint Hills has to access the pipeline; is there going to be some sort of written document saying who tears it up, who puts it back together, all of those different things. Mrosla replied that the applicant will have to enter into an encroach- ment agreement with Flint Hills; that agreement will specify in case of an emergency how cars will be moved, etc. He knows the applicant has to work with the tenants to notify them in case an emergency happens that they can move cars. That’s the worst -case scenario, as there are easements all over the place. It’s the applicant’s responsibility to work with their tenants on that. Bhat asked regarding their request for increasing the height of the building. He wasn’t sure who should answer this question, maybe the applicant, but can’t they change the footprint of the building. They have the horseshoe shape, they can maybe take out the sides or maybe the bottom U there, and thereby decrease the height. Mrosla stated he’d let the applicant address Planning Commission Minutes – Regular Meeting December 18, 2023 Page 6 of 9 that question, as he believed they had their architect here. They can talk about the site plan and how they reconfigured it. Rasmussen stated just to clarify, The Legends of Cottage Grove is two buildings, it’s not the White Pine, it’s the one next to it. Mrosla replied White Pine are the two buildings adjacent to the property; The Legends is a larger facility a little bit down the road. Rasmussen stated all right, so from an elevation standpoint, The Legends is the tallest building in that grouping, and this one will be slightly below that. Mrosla replied yes, and it’s also worth noting that we have contacted White Pine, with emails, phone calls, we’ve knocked on doors; we’ve done everything we can to try to get input, but we have not heard anything. So, we followed the normal proce - dures with every application, but to this point, we have not heard any comments or any con - cerns. He knows the applicant has reached out as well, trying to get their input. Frazier asked if the applicant would like to step to the podium. Travis Fauchald, Development Associate, Roers Companies, 2 Carlson Parkway, Plymouth, Minnesota, 55447, stated they’re a multifamily developer and have been around for just about 11 years. They predominantly do affordable housing and new construction projects in and around the Twin Cities and all over the country. Here, we’re proposing a workforce project, with a number of units being unrestricted, at market-rate rents, 20 percent of units at 60 percent AMI, and 5 percent of units at 50 percent AMI. We’re really excited to present this project, as we think it meets a lot of the City’s goals in the Comprehensive Plan. It is quite a challenging site, which is why we’re seeking some flexibility here. With our landscaping plan and tree count, the site is constrained; on the north part of the site, over by White Pine and the park land to the north, there’s a really sharp hill. What we’re ultimately doing to get to the 144 units is having to carve out a little bit, so, we’re proposing a retaining wall that is just north of our building that will run alongside the trail. That is kind of the site constraint to the north, and we want to plant trees and conserve trees on that hill, but also plant trees in a place that they’re going to survive. The site constraints on the south part of the site are an access easement he believ es that’s granted to the City to allow access to the stormwater on the northwest part of the site; he doesn’t believe a meaningful number of trees can be planted there. In the stormwater, we are una ble to plant there, and are unable to plant a certain type of tree that is in that gas pipeline easement. Mrosla has provided feedback to our design team, and we’ll certainly be working to get as many trees as we can to set them up for long-term success. Otherwise, we’ll find a way that will be satis- factory to the City to make sure we’re paying our fair share to meet Code with the trees. So, there will be some revisions made to the landscaping plan, and we’ll make sure that’s in a spot that works for everyone, prior to formal approval. Fauchald addressed comments on the gas pipeline easement. If something were to go wrong, we would obviously preserve the right to have Flint Hills’ repair team into the site. We’ll preserve and record an easement that will provide them access to make sure nothing is ever going to be in the way of their access to the pipeline. If something were to go wrong, they would need their excavators to come in and repair it; ultimately, that would be our expense. Once the pipeline is fixed, we would as a long-term owner operator, repair that and redo the parking lot if anything were to happen, God forbid it doesn’t. Fauchald stated they’re long-term owner operators; they have an inhouse property manage- ment company that will manage this site so we’re not going anywhere. We’re hoping to be really good partners, neighbors, and really good members of the community. Planning Commission Minutes – Regular Meeting December 18, 2023 Page 7 of 9 Fauchald stated on the building height, they’re seeking a height variance due to the site con - straints mentioned earlier. Ultimately, we are unable to expand our building footprint and in - crease the parking garage horizontally as we are constrained by the site boundary and the hill; we would have to dig out a lot more of the site, which is really expensive, and we’re really unable to go south or west with our site line. With that gas pipeline easement, we are unable to go further down to get more underground parking as there is bedrock underneath the surface. Those are the site constraints we’re working with to ultimately get to 144 units. If we were to remove a floor from our building and go a story shorter, the project , unfortunately, wouldn’t be financially feasible. So, that’s the background as to why we are building it at that height. Fauchald stated he’d be happy to answer any other questions. Our local architects, Kass-Wilson are here, they’ve done other projects in Cottage Grove. Loucks is our civil engineer and land- scape architect. So, if there are any questions he can’t answer, he’ll defer to the experts. Fauchald stated he appreciated their time and thanked them for their consideration. Frazier asked if there were any questions for the applicant. Rasmussen said with Fauchald’s experience with this development type, is it worth giving a little flexibility to 1.5 cars per unit; he asked if he’s pretty comfortable with that, that you’re going to be able to handle all of your parking at peak times. Fauchald replied yes, as across our other projects in the State of Minnesota, at this market rate or workforce project type, we see fewer drivers with those affordable units. Oftentimes, with one-or-two bedrooms, we see a single par- ent or parents with children; so, there might be only one driver or no drivers. Ultimately, there are some site constraints, but we have done projects at a lower parking count . We’re trying to get 1.5 and we will not provide anything less than that. As a long -term owner operator, we want to set this project up for success. Our property management team and the neighbors are not going to tolerate on-street parking. We feel comfortable there, we would like to propose some - thing that’s going to work for us as well as the community. We’ve done projects at lower parking ratios, but ultimately feel comfortable at 1.5. Frazier opened the public hearing. No one spoke. Frazier closed the public hearing. Rasmussen stated he knew this was a pretty challenging site, kind of a specialty site with high visibility, so it’s very important to our community. It seems like this fits in there pretty well, and they’ve done a pretty good job working with the site constraints, so he thinks it will be a good fit. Stephens stated she’d just add with all of her tree questions that it’s nice to see that you’re also asking for reduced parking. Many times we see tons of extra parking, but then there’s not enough room for trees or stormwater. So, she thinks it’s nice to see that in general you are actually constrained, and it seems like you’re doing what you can to fit in what you can. Frazier stated when he was reviewing this, the thing that jumped into his head was it’s interest- ing that some of these things that they’re asking for, they’re not just asking for a variance, be- cause he thinks there’s probably the factor there to get a variance. Instead of that, the applicant worked with the City to do a PDO so it benefits everybody; the City’s getting some of the things that we would like to see out of this project and you’re getting some flexibility. So, he thinks that’s also a good sign for a continuing relationship with the City and the community is that this Planning Commission Minutes – Regular Meeting December 18, 2023 Page 8 of 9 isn’t a we just need help, it’s a how can we make this work for everybody. He appreciates that, too. Stephens asked if he meant a PUD; Frazier said yes, maybe he said PDO.

Reports 8.1 Recap of November and December 2023 City Council Meetings Schmitz provided a summary of actions taken at the City Council meetings on November 1, November 15, and December 6, 2023. Director Schmitz wished the Planning Commission ers a happy holiday season and stated she was glad we were able to get back together before the end of the year. Before we know it, we’ll be in 2024, and we look forward to more big things. Khambata thanked Schmitz. stated Frazier had said PDO but that shows his length of tenure , because we don’t use that term anymore. PUD and PDO are kind of synonymous, Planned Development Overlay vs. Planned Unit Development. He caught that and it’s okay. He an- nounced there is a new Council Member, Monique Garza, who was sworn in at our last meeting. She’s lived in our community for nearly ten years, she’s got a husband and kids in the commu- nity. She’s responsible for Movies with Mo, the outdoor movies that we host in Highlands Park in the summertime, so she’s been active in volunteering in our community. She’s really looking forward to being able to help make a difference on the Council as well. He thanked the Planning Commissioners again for their time; he knows December especially gets to be busy for a lot of people, and he’s glad that he got to see all of their lovely faces again. With that, he said he’d stand for any questions that they might have. Frazier thanked Council Member Khambata, and said PDO is etched into his brain, and so it will never change. He will try, but he can’t make any promises. He asked if there were any questions for Council Member Khambata, but none were asked. 8.2 Response to Planning Commission Inquiries Frazier stated we had some inquiries from our October meeting. We received an email approx- imately a week later with those responses, so he’ll consider that filled. 8.3 Planning Commission Requests None.

Dear Ms. Matter, This letter acknowledges your request to link the Feasibility Report from the March 16, 2022, City Council meeting Item 07.A. to the January 17, 2024, meeting item 7.J. We appreciate your continued interest in this important project. However, upon reviewing your request, we find formally linking the 2022 report to the January 17, 2023, meeting is not necessary and is not legally required. Our decision is based on the following key factors: 1. Public Accessibility: The complete feasibility report for the South District Street & Utility Improvements – Phase 2 is already readily available on the City Council website at City Council (cottagegrovemn.gov). It features comprehensive details regarding the project, potential benefits, and associated costs. Public access to this information ensures transparency. The memo for item 07.J. stated the date the 2022 feasibility report was approved for easy reference. 2. Meeting Efficiency: To ensure balanced consideration for all agenda items, allocating time to review the previously approved 2022 feasibility report in a meeting might not be the most efficient approach. Prioritizing items on the agenda while still making the report readily accessible for residents to review online seems more practical and a better use of time. 3. Redundancy: Presenting the already accessible and approved report formally within the agenda might be perceived as redundant and could detract from the focus on more immediate needs regarding the project.

Budget Implication Included in the 2024 Budget. No increase in Public Safety transcription; $150 hourly rate - Meetings held in Council Chambers; $300 hourly rate - Meetings held outside of Council Chambers. Attachments 1. Agreement for Professional Services 2024 - Judith Graf (Transcriptionist Services) clean 1 TO: Honorable Mayor and City Council Jennifer Levitt, City Administrator FROM: Tammy Anderson DATE: February 7, 2024 RE: Transcribing Agreement Discussion For many years, Judith Graf has been providing transcription services for the City of Cottage Grove. This includes transcribing minutes for the City Council, Economic Development Authority, Convention and Visitors Bureau, Planning Commission and Public Services Commission meetings and Public Safety statements and phone calls. Most meetings Ms. Graf transcribes are held in the Council Chambers and video recorded by SWCTC. This is a nice tool for transcribing because it allows Ms.Graf to see who is speaking. However, there are special meetings and workshops held by the Council in city meeting rooms that are not video recorded and use an audio recorder. Ms. Graf experiences a significant increase in the time required to type these minutes. Instead of billing the City based on the duration of her transcription process, Ms. Graf invoices per audio meeting minute. In order to receive fair compensation, the 2024 agreement reflects a rate of $150 per audio hour for meetings that are video recorded in the Council Chamber, and $300 per audio hour for meetings held outside the Council Chamber without video. For the Public Safety portion of the 2024 agreement, the prices will remain the same as 2023 at $3.50 per audio minute transcribed for Public Safety phone calls and $4.00 per audio minute transcribed for STAT transcription requests or audio files where two or more people speak throughout the audio and requires a certificate of accuracy of the transcription. The staff are very happy with the services Ms. Graff provides for the City and will continue to provide her with materials and documents to make her job as efficient as possible.

Budget Implication N/A Attachments 1. Second Amendment to JPA for HERO Center - redline 2. Second Amendment to JPA for HERO Center - clean 1 TO: Honorable Mayor and City Council Jennifer Levitt, City Administrator FROM: Pete Koerner DATE: February 7, 2024 RE: HERO Center Joint Powers Agreement (JPA) Amendments Discussion The City of Cottage Grove and City of Woodbury entered into the Joint Powers Agreement to operate the HERO Center in 2018. It has only been amended once, in 2019. The JPA has been serving the parties very well since its original adoption. We recently inquired with the League of Minnesota Insurance Trust (LMCIT) if it would insure the HERO Center as its own entity. After its initial review of the JPA, LMCIT declined, and raised some questions about whether the HERO Center was truly acting as a joint powers entity, or if the real decision-making authority rested with the two cities. City Attorney Kori Land spoke with the attorney at LMCIT about the practices and operations of the HERO Center and was able to explain that the governing Board (FOC) has the authority to make all operational decisions, enter into contracts, approve spending, adopt a budget, etc. Based on the actual operations, LMCIT agreed that the HERO Center met the requirements of a “joint powers entity” for insurance purposes. However, if the HERO Center intends to carry its own coverages, then LMCIT suggested some changes to the JPA to make it clearer that it truly acts as a joint power entity. For insurance coverages, the HERO Center could carry liability, property and Work Comp. coverages. The covered parties would include the HERO Center itself, its employees, the FOC, the two cities, the City Councils, and city employees. Currently Cottage Grove carries the Work Comp. coverage and if the employees remain employees of Cottage Grove, then the Work Comp. coverage remains with the City of Cottage Grove. If the FOC decides at some point in the future to hire the employees under the entity of the HERO Center, then the HERO Center would need to add Work Comp coverage to the insurance package. As long as we were reviewing the JPA to incorporate the suggested revisions from LMCIT, it seemed appropriate to remove outdated provisions in the agreement at this time. To that end, we proposed the following revisions: Insurance Related Revisions: 2 o Article III Section 3.7: The additional listed powers provide reassurance to LMCIT that the JPA creates an insurable joint powers entity. o Article V Section 5.5: This new language makes it clear that each parties’ employees are covered by their own Work Comp. claims. o Article VI, Section 6.1: LMCIT insures both cities and has an exclusion in each city’s policy for claims that arise out of a JPA. Therefore, the HERO Center must agree to defend and indemnify the individual members of the JPA. o Article VII, Section 7.1: When there is a 3rd party claim that is covered by insurance, LMCIT will appoint an attorney to defend the HERO Center, so this provision stating that the parties will recommend an attorney is unnecessary. o Article IX: Insurance: This was added by LMCIT to list the specific insurance coverages required. Other Recommended Revisions: o Article V, Delete Sections 5.1 and 5.2. We recommend deleting these sections, which were solely related to the construction of the facility. This also allows the deletion of Exhibit A, which identified the Project Costs. o Article V, Delete Section 5.6 and Revise 5.7. These sections were specific to the operating budget for calendar years 2018, 2019 and 2020. Now that there is an established cost-sharing formula, we can simplify the language. o Article XV, Delete Section 15.10: Delete the reference to the 2016 Memorandum of Understanding. On January 17, 2024, at the HERO Center’s Facility Operation Committee (FOC) meeting, City Attorney Kori Land presented the suggested revisions to the JPA. Woodbury’s City Attorney also reviewed. After discussion, the FOC unanimously approved the revisions to the JPA and recommended sending to each City's Councils. Recommendation Approve the second amended Joint Powers Agreement between the City of Cottage Grove and the City of Woodbury for the East Metro Public Safety Training Facility (HERO Center).

Each Party shall be responsible for injuries to or death of its own personnel. Each Party will maintain workers’ compensation insurance or self-insurance coverage, covering its own personnel. Each Party waives the right to, and agrees that it will not, bring any claim or suit against the HERO Center or the other Party for any workers’ compensation benefits paid to its own employee or dependents, that arise out of HERO Center operations or activities, even if the injuries were caused wholly or partially by the negligence of any other Party or its officers, employees, or volunteers. 5.105.6 Unanticipated Expenses. “Unanticipated Expenses” are expenditures that are not included in the Operating Budget but are necessary for the continued operation of the HERO Center. The Facility Operations Committee shall attempt to meet and determine the necessity of approving and incurring an Unanticipated Expense.

Each Party agrees to pay its Percentage Share of all Unanticipated Expenses approved prospectively or retroactively by the Facility Operations Committee. Cottage Grove will invoice Woodbury for its portion of the approved Unanticipated Expenses and payment will be due within 30 days after receiving an invoice from Cottage Grove.

The Facility Operations Committee shall attempt to meet and determine the necessity of approving and incurring an Unanticipated Expense. If such meeting is not possible in a timely manner and approval of the Unanticipated Expense is considered critical and time-sensitive Cottage Grove shall have sole discretion in approving and incurring an Unanticipated Expense.

Gridley City Administrator Dated: 1 City Council Action Request 7.M. Meeting Date 2/7/2024 Department Parks and Recreation Agenda Category Action Item Title Kingston Park Building Final Design Service Agreement Staff Recommendation Authorize service agreement with Oertel Architects for Kingston Park Building Project final design services. Budget Implication $185,500 in 2025 CIP for project from the Park Improvement Fund Attachments 1. 1-Memo-Kingston Plan Development 2. Kingston Park Service Agreement To:Honorable Mayor and City Council Jennifer Levitt, City Administrator From: Cc: Zac Dockter, Parks and Recreation Director Date:January 22, 2024 Subject:Kingston Park Building Final Design Service Agreement Introduction In January, City Council reviewed the Kingston Park building conceptual designs with the project team and responded favorably. City Council directed staff to prepare a service agreement for final design services with Oertel Architects. Background The Kingston Park conceptual design was thoroughly reviewed by the project team, stakeholder groups and City Council. The following modifications to the conceptual design have been recorded for incorporation into final design work: 1. Increase kitchenette serving window size to the outside. 2. Consider traffic flow for events that may utilize kitchenette and portable grills or food stations. 3. Maximize picnic space and flow. 4. Address site electrical needs for larger events including below surface outlets for food stations/trucks, audio setups or other mobile event needs. 5. Vertical entry monument received favorable response for its unique stature but imagery and/or words should be modified to perhaps include directional signage, art imagery or other unique elements. No extruding or climbable pieces should be on the sign. Staff has worked with Oertel Architects to secure a proposal for final design services. The scope of services includes: 1. Design Development 2. Development of Construction Documents 3. Project Fee Projections Exhibit A within the service agreement details the work, specialties and deliverables from each service scope listed above. The cost for architectural services is $124,500. Further, the proposal also includes cost estimates for bidding and construction administrative work should City Council order the project. These include: 1. Completion of Bidding Documents 2. Bidding Process Administration 3. Construction and Contract Administration Costs for bidding and construction services is estimated at $61,000. Because Oertel contracts engineering services, these fees are subject to change based on final project schedule. Without a firm construction schedule from the City, Oertel is protecting itself from a financial commitment that may be impacted by a delayed construction start date. We would expect minimal increases to the proposed fees if the project is ordered within the next two years. If the project is delayed beyond two years, staff will negotiate this portion of the fee structure by comparing professional service rates to industry standards. Staff Recommendation Authorize service agreement with Oertel Architects for Kingston Park Building Project final design services. 1 AGREEMENT FOR PROFESSIONAL SERVICES THIS AGREEMENT (“Agreement”) is made and executed this _____day of ____________, 20 , by and between the City of Cottage Grove, 12800 Ravine Parkway, Cottage Grove, Minnesota 55016, (“City”) and Oertel Architects, 1795 St. Clair Avenue, St. Paul, MN 55105 (“Consultant”).

CITY OF COTTAGE GROVE By: Myron Bailey, Mayor By: Tamara Anderson, City Clerk 6 CONSULTANT By: Its: Date: 1795 St. Clair Avenue St. Paul, MN 55105 (651) 696-5186 www.oertelarchitects.com City of Cottage Grove – Kingston Park Building. Date: January 22, 2024 To: Zac Docter, Park and Recreation Director, City of Cottage Grove CC: Project: Kingston Park Pavilion Project RE: Final Design Cost Proposals and Scope Purpose This memorandum is providing the City of Cottage Grove a fee proposal for “final design” phases to advance the accepted conceptual design for Kingston Park Building. This fee proposal will provide an overview to describe work efforts and tasks that are being assumed and included in the design scope to establish the proposed fee. Project Understanding The advancement of this project into “Final Design” is based on the City Council general acceptance of the conceptual design and desire to further advance the project. Oertel understands that funding for the construction of the project is not currently scheduled or available. However, there is a desire to advance the design further to provide a more detailed design that can result in a more detailed cost opinion to help facilitate funding the project for construction. To that goal, Oertel is providing two separate design fees for Final Design milestones at 60% total design completion and 90% design completion. In both cases, full building engineering is being provided. This includes structural engineering, plumbing and HVAC engineering and electrical engineering. As discussed with city staff, site / civil engineering will be provided by City Staff where it will be required. Based on the scope of work proposed in the Conceptual Design process, the site / civil design work will be limited and much of the work can be incorporated into Architectural site plans. The level of engineering for each design milestone will be briefly described in the following scope of work description.

Attachments 1. 1-Memo - Concept Design Architect Agreement 2. 2-RFP - Dunes Building 3. Dunes Architect Service Agreement Signed To:Honorable Mayor and City Council Jennifer Levitt, City Administrator From: CC: Zac Dockter, Parks and Recreation Director Date:February 1, 2024 Subject:Mississippi Dunes Building Concept Design Development Introduction/Background As active development plans for the former Mississippi Dunes Golf Course materialize, the park master plan for the site plays a critical role in the project’s overall success. The 2021 Mississippi Dunes Park Master Plan does an excellent job of prioritizing and mapping recreational and natural amenities on the site. However, some site modifications have been proposed through development submittals. These modifications include a realignment of the entry road as well as an opportunity to acquire additional park property to the south and west of the original master planned site boundaries. Because the building plays such a prominent role to the park site, staff is recommending development of concept designs. These concept designs will set the focus of the park site so that any planned parking lots, trails, landscaping and supporting recreational features can be tied together using the building as the activity hub. As concept plans are finalized, they can be used to steer direction for any potential site development and/or public improvements. The staff project team highlights the following key directives to be considered during concept design: 1. Design focused on accentuating the natural and cultural history of the site. 2. Higher design standard than standard park inventory including accessibility designs. 3. Accentuate an adjacent picnic awning. 4. Public restrooms sized to serve smaller events and classroom style programs. 5. Standard multi-purpose room for year-round programming and rentals. 6. Small serving kitchen. 7. Natural and cultural interpretive elements inside the building. 8. Interpretive landscape design for beauty, education, functionality and habitat benefits. 9. Provision of options for environmentally friendly building features. Staff completed a Request for Proposal process for concept design services in January. Proposals were reviewed and two architects, ISG and HGA, were interviewed by the staff project team on January 30. Both firm’s proposals are included with this report, and both are well qualified for the project. After extensive review, the staff project team recommends the hiring of ISG for Mississippi Dunes concept design development. Because this is a new park development, it is recommended that the $28,600 project cost be paid from the Park Trust Fund. There is currently $15,000 budgeted in the CIP from this funding source for park master planning. Staff Recommendation Authorize service agreement with ISG, Inc. for Mississippi Dunes building planning and concept design. Proposal Request for Cottage Grove Mississippi Dunes Park Reserve Building Conceptual Design Objective Hire an architectural consultant team to guide the City of Cottage Grove in developing conceptual designs for a future Mississippi Dunes Park Reserve building.

Working closely with the City’s Parks & Recreation and Planning Departments, ISG developed a conceptual master plan that parceled the site to meet various stakeholder needs and goals, while preserving and expanding the land’s natural resources. The primary element of the master plan was the riverfront public park design connecting people to the river, its many water trails, and new park amenities. Understanding that the City desired a more passive design approach to minimize land impact, ISG developed three concepts ranging from highly programmed options to more minimal site developments. The preferred concept clusters more active spaces around a new four-season park building, which includes parking, a nature-based playground, open lawn area, and terrace patio that takes advantage of the views to the Mississippi River. Closer to the river’s edge, the boat launch and docks allow visitors to engage with the river in a way not previously possible. Further out, the site is minimally impacted, and simply enhanced with crushed stone and mowed trails, secluded picnicking nodes, and tiered stone river access points. PROJECT EXPERIENCE Architecture + Engineering + Environmental + Planning | ISGInc.com Page 4 of 11 ROUND LAKE PARK BUILDING Eden Prairie, MN ISG worked with the City of Eden Prairie to develop a master plan to reimagine an existing park building scheduled for demolition near Round Lake. The new park building, which was completed in December 2023, supports a community event space for 50-75 people, provides restroom and changing room amenities for swimmers using the lake, nearby splash pad, and pool, and includes a warming house for winter activities. The modern park building was designed with angular forms and expansive windows to provide optimal views of the lake and park from every side of the building, including from the performance stage area that is used for the city’s annual Fourth of July celebration. Wood elements and metal paneling provide a subtle tonal contrast and sophisticated aesthetic while blending into the natural themes of the park environment. The design uses sustainable practices, including solar powered electrical systems, green roof fueled by stormwater, and geothermal technology. PROJECT EXPERIENCE Architecture + Engineering + Environmental + Planning | ISGInc.com Page 5 of 11 GLEN PARK River Falls, WI Glen Park nods to the history of the site through its architecture, dynamic natural landscapes, and recreation opportunities that include a series of nature and paved trails that connect to a greater trails system. With ISG’s multi-disciplinary expertise and approach, the team was able to respect the history of the setting with traditional beauty and impart feedback from multiple stakeholder groups while providing expanded multi-generational amenities. Design included a FEMA-rated storm shelter with a four seasons pavilion, a splash pad, and pool and playground improvements. The reorganization of entry points, parking, and trail connections maximize available park space and minimize conflict between pedestrians and vehicles. Limited impact strategies were deployed to protect the extensive tree canopy. The team worked closely with the City to ensure design details and maintenance protocols supported long-term success. Since construction, the park pavilion has seen enthusiastic approval by the community through frequent reservation, from weddings and class reunions to local classes and a high school gymnastics banquet. The City has tallied the pavilion’s use at 219 reservations in 2021, and at 255 reservations in 2022—showing the great value of their investment. PROJECT EXPERIENCE Architecture + Engineering + Environmental + Planning | ISGInc.com Page 6 of 11 WEBSTER COUNTY NATURE CENTER Fort Dodge, IA Partnering with Webster County Conservation, ISG developed their Parks, Facilities, and Recreation Master Plan to maximize natural resources, support tourism, and revitalize the Des Moines riverfront. ISG’s in-house planning team supported WCC with the submission of a $4.5 million Destination Iowa Grant, allowing them to implement a nature play area, river walk, multiple water access points, and shoreline restoration. Construction of a new Webster County Nature Center is nearly completed, which will support community education, staffing growth, and city-wide redevelopment efforts. Building designs for the center were oriented to take full advantage of the scenic Des Moines River views. Angled roof planes serve not only as a unique aesthetic feature, but direct water to bioretention cells that filter building and surface runoff before entering the river. Other sustainable design practices include native plantings, high-efficiency HVAC system, occupancy and daylight sensors within the lighting system, and building preparation for future roof solar panels. The 14,000-square foot building will serve as an exhibition space to educate youth and visitors about water quality through interpretive displays that demonstrate how water is treated before it enters waterways and the natural water cycle. The space also includes WCC administrative offices and indoor and outdoor classroom spaces to support student field trips and community gatherings. PROJECT EXPERIENCE Architecture + Engineering + Environmental + Planning | ISGInc.com Page 7 of 11 JAY C. HORMEL NATURE CENTER Austin, MN From the beginning, the Jay C. Hormel Nature Center (JCHNC) and its 508-acre site was meant to inspire families to enjoy and appreciate the great outdoors. To demonstrate sustainability practices and educate visitors about the environment, ISG designed an interpretive center and developed a long-range master plan for phased site improvements. Throughout the Center’s design process, environmental values and sustainability goals shaped building plans. ISG incorporated energy and water efficiency practices, including an interconnected, ground mounted photovoltaic system to produce solar energy for the building. A ground loop geothermal system offers low maintenance, cost-effective heating/cooling. Educational opportunities throughout the space included habitat exhibits, live birds of prey, environmental interpretive signage, an aquarium containing Minnesota aquatic life, an early childhood space for sensory play, a natural history resource library, two classrooms, and a multi-purpose room. With ideas for site development, JCHNC desired a long-range master plan to prioritize improvements and assist with budget planning. ISG facilitated an extensive engagement effort which garnered feedback focused on expanding programming opportunities to serve a wider demographic and draw in new users. The final master plan serves as a road map for annual improvements and provides direction regarding expansion and restoration efforts, additional programming, amenity improvements, and project phasing To complement the recently constructed Center, conceptual designs for the amphitheater integrated themes of natural wildlife and vegetation, and used natural materials such as river rock, wood/recycled lumber, and native plant materials. Cast stone tiered seating, a wood stage, and custom designed shade structures beautifully blend into the wild, picturesque landscape, offering visitors relaxing seating and gathering options. The conceptual designs for this reimagined amphitheater provide a compelling visual to help JCHNC staff fundraise to realize the vision. PROJECT EXPERIENCE Architecture + Engineering + Environmental + Planning | ISGInc.com Page 8 of 11 NEY NATURE CENTER MASTER PLAN Henderson, MN The Ney Nature Center and Le Sueur County are collaborating on a park building project to enhance local engagement in nature programs, restoration initiatives, and community events. The site’s rich history and nature amenities led to a linear building design for optimal views. The facility design prioritized accommodating large groups for events with a flexible layout for overflow seating and utilization of indoor and outdoor spaces. Accessibility improvements included an ADA trail around the pond and enhanced on-site parking for both vehicles and pedestrians. Programming challenges involved addressing topography issues around the pond and creating an ADA route. A zigzag-type trail was designed for an interactive stormwater educational experience, relying on existing topography for the pond trail. The playground was divided into flat and accessible spaces and areas inspired by natural play. ISG presented the comprehensive master plan to the Ney Nature Center and Le Sueur County park boards, which emphasizes site views, linear layout, and accessibility. Recommendations focused on maximizing site views, adopting a linear layout to separate public and staff facilities, and balancing accessibility with topography challenges. Overflow parking within the proposed space was suggested to minimize impact, and stormwater collection systems were integrated to address elevation changes. The client is securing grants to fund the project. The design aligns with the goals of Ney Nature Center and Le Sueur County and creatively addresses challenges, ensuring a sustainable integration of the building with the natural surroundings.

We’ve brought this deep knowledge to Dakota County’s Whitetail Woods Regional Park, Hennepin County’s Theodore Wirth Park Trailhead, Washington County’s Ravine Regional Park Lower Landing, and the Water Works Park on the Mississippi river in Minneapolis. We’re excited to build on our past success to create with you a new and exciting legacy for Cottage Grove residents. DESIGN OPPORTUNITY The City of Cottage Grove has more riverfront shoreline than any other municipality in the Twin Cities area yet has very limited public river access. Further, being adjacent to both Grey Cloud Island and Grey Cloud Dunes Scientific and Natural Area (SNA), a deep ecological and indigenous heritage are present. This project presents a once in a lifetime opportunity for civic leaders to establish a public foothold along the Mississippi waterway and to provide a connection to the unique ecology and indigenous history of this area. Named after the sister of Dakota Chief Wabasha (Mar- pi-ya-ro-to-win), Grey Cloud Island has a long history of indigenous settlement. The upper island was home to Mdewakanton band headed by Medicine Bottle and the lower island features the largest concentration of burial mounds in Washington County. The Mississippi Dunes Park Reserve Building overlooking Grey Cloud Island is an unparalleled gateway to this history and to the unique ecology that’s allowed settlement to thrive. Grey Cloud Dunes SNA is home to the Twin Cities’ largest intact prairie system, with roiling sand hills, Oxbow scrub, and meandering drifts of bluestem. Dune ecosystems are extremely rare in Minnesota. As a result, this place is highly valued for its ecological and topographical diversity, as well as the proliferation of rare and unusual plant species. Bald eagles, lark sparrows, foxes, and northern long-eared bats all call this home. We believe this project is not only an opportunity to protect and maintain the ecosystem of the SNA, but also be a catalyst for site regeneration. CONNECTING PEOPLE WITH PLACE The architectural and site design should be as unique as the distinctive heritage and ecology of this area. The project should both be a vessel to tell stories about people and place; and act as a teaching tool for the public to share, engage, and inspire. HOLISTIC DESIGN Mississippi Dunes Park will be a sanctuary for people and wildlife. This project needs thoughtful and sensitive outcomes that respect the intrinsic value of this place. We believe the best outcomes are informed from multiple perspectives. This is reflected in our commitment to engagement and how we established our leadership team. HGA’s team harnesses expertise in design anthropology, architecture, landscape architecture, equity, and sustainability to provide a holistic, integrated approach to design. All the competencies required to support the City of Cottage Grove and execute this project reside within HGA. INTEGRATING INCLUSIVE AND ACCESSIBLE DESIGN The very nature of this project is about access. It’s about removing barriers and connecting the next generation of residents to the Mississippi. This extends to the site and building design, where Universal Design will be of utmost importance to ensure inclusivity for all. This endeavor will be supported by extensive research into the rich tapestry of backgrounds and abilities of Mississippi Dunes Park visitors. 1. Mississippi Dunes sketch by Landscape Architect Luke Nichols 4 | HGA Project Understanding | 5 PROGRAMMING NEEDS Stakeholder Interviews • The project team will conduct interviews with staff and project stakeholders to evaluate the programmatic and operational vision and needs for a new building. Topics discussed will include overall community values, trends in programming and facilities, levels of service provided and desired, among others. • Based on our current project understanding, stakeholder groups may include future building staff and city staff, but we will jointly identify prospective stakeholders. Site and Building Program Building on the data gathered, a quantitative building space program will be created. Such a program will quantify specific amenity spaces by establishing room quantity, size, and user capacity. As the building programs become defined and keeping in mind potential expansion footprints that will impact surrounding site features and amenities, the design team will propose holistic design solutions that maintain the integrity and intent of the Mississippi Dunes Park Master Plan. PLANNING & CONCEPT DEVELOPMENT Based on the building and site program, the team will explore design concepts, that represent the desired project scope. The explorations will be presented in site plan drawings and floor plan diagrams. Multiple options facilitate a process of cross-evaluations with all stakeholders to determine the optimal long-term solution. The intent of this phase is to seek consensus on an ideal design. The preferred design concept will be rendered in 3D that show the building’s context, form, materiality, site, and visitor use. PROJECT COST ESTIMATING Leveraging HGA’s cost estimating expertise, construction costs will be developed for the preferred design option. Hard construction costs and estimates for project-related soft costs, such as furnishings, will be combined to establish an overall project cost for the City’s use in strategic planning. Key to accurate conceptual estimating is knowledge of the marketplace, historic cost data for similar projects, and coordination between the design team and the estimators – all things our team brings together for a reliable estimate. FINAL PRESENTATION The entire process will be aggregated into a final presentation that will provide comprehensive data and imagery for use by the City of Cottage Grove. WHY OUR TEAM? • We are a multidisciplinary team with a deep bench of expertise in architecture, engineering, cost estimating and sustainability—everything you need for a successful project. • We are familiar with the trends, needs, and future of parks and recreation through participation in organizations such as MRPA and NRPA, as well as the design and construction industry. • We understand the complex nature of stakeholder engagement and can facilitate a dynamic, collaborative process. • We bring together optimal programming opportunities with award-winning community and recreation architecture. • We are committed to creating meaningful places for community health and well-being. PROJECT SCOPE The Mississippi Dunes Park Reserve Building represents a rare opportunity to provide Cottage Grove with public access to the Mississippi River and the unique and beautiful ecology of this unusual site. There’s a lot at stake with this project. Our team will guide you every step of the way, asking the right questions of the appropriate stakeholders. Several factors will be considered in our study, including: • Assessment of usage, space needs, and site areas • Program options and operational goals informed by staff and stakeholder engagement • Site design options that include recreational use opportunities adjacent to the building • Building design options that are unique, beautiful, and fulfill your programmatic needs • Coordinating design/technical information for cost estimating site and building options • Balancing current needs against future trends The culmination of this study will be a comprehensive assessment that informs a final design concept that’s uniquely Cottage Grove. A final presentation will provide the City with the guiding principles, research, design concept, and renderings needed to help make the right decisions for this project. PROJECT APPROACH AND OBJECTIVES The HGA team will work rigorously to understand and thoughtfully respond to the programmatic and physical context of the Mississippi Dunes Park Reserve Building. The team proposed to lead the project offers extensive experience in needs assessment, planning, and design. While each project approach is customized to the specific needs of the community, we offer the following process outline: REVIEW OF EXISTING INFORMATION The City may have captured information relevant to the study that the design team will want to include and understand as a data point in the overall concept design process. This information may include site surveys, site documentation, geotechnical reports, historical data, or other forms of information. Our team will use this information to inform concept design and project scope. 6 | HGA Project Understanding | 7 Ideas that answer to the future.

The wood framing sequesters carbon and promotes the client’s sustainability goals. The innovative design takes advantage of the two-way spanning capabilities of CLT to form a thin cantilevered profile around the roof edge without the supplemental members that would have been necessary with conventional wood decking. Careful coordination between disciplines allowed electrical work to be integrated with the roof to provide concealed conduit within the exposed structure. Lighting conduit was slotted into the top surface of the CLT in the shop prior to installation. The 6,000 SF roof was installed in just over one day and the entire mass timber structure was built in just one week. The new facility features a warming lobby, parks and recreation office, a rentable multipurpose space with kitchenette, equitable restrooms, park storage, and a covered picnic area. The site design included rerouting the park’s ski trail to further activate the building as well as adding two exterior gathering spaces that orient park visitors to the trail.

Bruce Karnick Hastings Journal News COTTAGE GROVE RAVINE REGIONAL PARK WASHINGTON COUNTY | LOWER LANDING TRAILHEAD BUILDING | COTTAGE GROVE, MINNESOTA A 522-acre park with steep ravines, rolling hills, and Ravine Lake, this park hosts pristine opportunities for hiking, fishing, cross-country skiing, and picnicking. 16 | HGA Relevant Experience | 17 WATER WORKS MINNEAPOLIS PARK & RECREATION BOARD | WATER WORKS | MINNEAPOLIS, MINNESOTA Minnesota is home to a 72-mile-long national park, the Mississippi National River and Recreation Area, that runs through the urban cores of both Minneapolis and St. Paul. As part of a plan to enhance the experience of the iconic St. Anthony Falls area for tourists and residents alike, the Minneapolis Parks Foundation, the Minneapolis Park and Recreation Board (MPRB), with restaurant partner The Sioux Chef, entered a public/private partnership to develop the land. Now dubbed Water Works, a three-acre site within Mill Ruins Park, the project features greenspace with native foliage and a two-story pavilion that includes outdoor plazas, visitor amenities, and a new restaurant. Formerly a vacant, distressed industrial parcel in downtown Minneapolis, the Water Works Park Pavilion and park project is one of the initial projects of the RiverFirst Initiative, started in 2010 by MPRB in partnership with the Minneapolis Parks Foundation, a vision for transforming an 11-mile stretch of land nestled along both sides of the Mississippi Riverfront. To help shape their vision of the future while understanding the design reverence needed for the project, the MPRB selected Damon Farber Landscape Architects to lead the project with the national interdisciplinary design firm HGA.

LOUIS PARK | ST. LOUIS PARK, MINNESOTA Westwood Hills Nature Center (WHNC) is a 160-acre nature park featuring prairie, forest and marsh areas, with immersive trails and an educational center. WHNC sought to replace their small, aging facility with a new building aimed at connecting community to nature.. MISSION, PROGRAM, AND FUNCTION The Westwood Hills Nature Center project reflects the city character in its vision and design - a resilient exemplar of a sustainable future. With the primary mission of the Nature Center being to connect people to the environment, the city challenged the team to create a zero-energy building to serve as a pilot for its new Green Building Program and Climate Action Plan. To reinforce sustainable building practices, the new facility serves as a teaching tool itself, demonstrating its passive and active strategies for energy efficiency and stormwater management, in addition to showcasing interpretive exhibits which highlight Minnesota landscape and wildlife habitat. PERFORMANCE AND TECHNICAL INNOVATION The use of future weather data models played a key role in verifying the performance of building systems well into the future. The team led a resilience workshop for project stakeholders to assess potential risks to the building over its life span including everything from public safety scenarios through impacts of climate change. ECONOMICS AND SCHEDULE The design team used several analytical design tools to establish strategies and test efficiency through the design process, including solar radiation analysis, wind direction, and daylighting/glare analysis. An energy model was regularly updated as the design evolved, and all disciplines collaborated to fine tune the thermal envelope and building loads along the way to ensure performance would be achieved as economically as possible. The project faced some substantial weather delays which affected the installation schedule of the roofing system. The HGA team was able to revise the roofing system in a timely manner to allow for cold weather installation and avoid further schedule delays. SUSTAINABLE OPERATIONS GOALS: ZERO ENERGY Part of a City effort towards a sustainable future, WHNC serves as an exemplar for sustainability strategies and has achieved International Living Future Institute‘s (ILFI) Zero Energy Certification. Building envelope, orientation, and shading were optimized for efficiency and organized to take advantage of existing site resources—sun and wind—and maximize use of passive strategies. The design uses thermal mass for winter solar gain and in-floor radiant heating to achieve occupant comfort during cold weather, as well as “task oriented” passive and active ventilation strategies with operable windows and ceiling fans as low energy means of achieving occupant comfort in warmer months. On the active side electrical and mechanical systems’ energy loads were reduced using daylighting throughout and a geothermal wellfield to supplement the all-electric boilers as a heat source for radiant heating of the floor slab. A rooftop solar photovoltaic system offsets annual energy use, and the building has achieved Zero Energy certification.

Meeting Date 2/7/2024 Department Community Development Agenda Category Action Item Title Holcim MWR, Inc. – Annual Mining Permit Staff Recommendation Adopt Resolution 2024-016 approving the 2024 Mining Permit for Holcim – MWR, Inc. – Nelson Sand & Gravel Facility. Budget Implication N/A Attachments 1. Holcim Mining Permit CC Memo 2. Holcim Mining Permit Exhibit A 3. Holcim Mining Permit Resolution TO: Honorable Mayor and City Council Jennifer Levitt, City Administrator FROM: Mike Mrosla, Senior Planner DATE: January 26, 2024 RE: Holcim MWR, Inc. – Annual Mining Permit Proposal Holcim MWR, Inc. (Applicant), formerly Aggregate Industries, has submitted their annual mining permit application to continue mining and processing aggregate materials in the Nelson Sand and Gravel Facility located at 11250 Grey Cloud Trail. The aggregate materials will be incorporated into various products in the Twin Cities metropolitan area and are used for ready mix concrete and/or asphalt in the construction of highways and buildings, etc. A copy of Nelson Sand & Gravel Plant 2024 Mining Plan is attached. The 2024 Mining Operations Plan proposes the following: • Mining and processing approximately 700,000 to 750,000 tons of aggregate materials. • Processing, washing, screening, and loading aggregate materials onto barges and trucks. • Operating 24 hours per day seven days a week (Resolution 95-28). Location Map Honorable Mayor, City Council, and Jennifer Levitt Holcim MWR, Inc. – Annual Mining Permit January 26, 2024 Page 2 of 5 Review Process Application Received: December 15, 2023 Acceptance of Completed Application: December 15, 2023 City Council Date: February 7, 2024 60-Day Review Deadline: February 13, 2024 Planning Commission The Planning Commission reviewed the application at their January 22, 2024 meeting. The Commission unanimously (6-to-0 vote) recommended approval of the request with no discussion. Ordinance Requirements City Code Title 3-9 requires that an annual mining permit must be reviewed by the Planning Com- mission within 60 days after the completed application has been accepted by the City. The Plan - ning Commission’s recommendation is forwarded to the City Council for final action. The purpose of the annual mining permit is to: • Ensure the restoration of the mined area is consistent with existing and planned land use patterns and to promote appropriate reuse of the mined areas. • Ensure conformity of mining operations with the City’s Critical Area and Comprehensive Plans. • Control the effects of noise, dust, erosion, traffic, drainage, ground water pollution, and other factors related to mining in general. Background Mining at the existing Nelson Sand and Gravel Mine Facility has occurred since the early 1950s when the J.L. Shiely Company (now known as Holcim Industries) entered a lease agreement with the private landowner. A form of this lease agreement remains in place between the private land- owner and Aggregate Industries today. On October 12, 1982, the Lower Grey Cloud Island Reclamation Concept Plan was approved by a City of Cottage Grove Reclamation Committee. A mining plan prepared by B.B. Chapman in 1982 is part of that document. A copy of this plan is shown below. With some exceptions, the proposed 2023 Operations Plan generally replicates landforms and topography as approved in 1982. 1982 Reclamation Plan Honorable Mayor, City Council, and Jennifer Levitt Holcim MWR, Inc. – Annual Mining Permit January 26, 2024 Page 3 of 5 Mining Operations Mining Operations consist of dredging to excavate raw aggregate materials. Dredging is used to reach sand reserves below the water surface. Its de-sanding capability and initial crusher that crushes rocks to smaller than six inches in size allows the operator to reclaim up to 400 tons of sand per hour without unnecessary re-handling. The dredge can mine 1,200 tons of aggregate material per hour at 60 feet below the water surface. After the material is excavated by the dredge, the mined aggregate is transported by a conveyor system that is about 2.2 miles long to the pro- cessing plant located at the northwest side of Lower Grey Cloud Island. The processing opera - tions include crushing, washing, sorting, and stockpiling aggregate materials by size. These materials are then loaded onto barges or trucks. Most of the material is transported by barge up the Mississippi River to distribution yards in St. Paul. In August 2023 the Applicant added a fully electric floating suction dredge that was used to move waste sand overburden from an area which was previously mined in the 1970s to 1980s. The suction dredge has the ability to reach depths of 60 feet below water and will work in con junction with the existing dredge. While the existing dredge will continue to mine material for pro cessing and sale, the new suction dredge was used to solely pump a slurry of overburden sand and water away from the active mining area. The overburden sand moved by the suction dredge will be placed in areas to support the final reclamation of the site. Annual Mining Report In 2023, approximately 675,000 tons of aggregate were transported up the river while approxi - mately 61,000 tons were transported by truck to local job sites. 2021 2022 2023 Estimated Tonnage Transported by Barge 721,500 607,000 675,000 Estimated Tonnage Truck Transportation 18,000 60,000 61,000 Planning Considerations Proposed Mining Operations The 2024 Operation Plan is shown below, and a copy is attached to this planning staff report. 2023-2024 Operations Plan Honorable Mayor, City Council, and Jennifer Levitt Holcim MWR, Inc. – Annual Mining Permit January 26, 2024 Page 4 of 5 Proposed 2024 Operations Plan As shown above, the proposed mining activity will be contained in the same area as the 2023 operation plan. The Applicant is proposing to export approximately 700,000 to 750,000 tons of material in 2024. Like previous operation plans, the applicant is required to take appropriate measures to ensure there is no erosion to stockpiles or earth-berms. At the base of each slope, a channel must be constructed to control runoff. The channeled water shall be diverted to a sed - imentation basin before being allowed to enter any natural drainage system. Erosion control measures must be implemented within a reasonable amount of time for the stockpile and berm. Environmental Impact Statement Process The Applicant is in the process of working on an Environmental Impact Statement for proposed expansion of their mining operations in the Mississippi backwaters, located to the southeast of the existing facility. Reclamation Plan As of 2024, approximately 265 acres of the site have been reclaimed. The 2024 restoration plans include ongoing restoration efforts in creating a large lake and peninsula by providing shore stabili - zation/establishment and re-vegetation. Continued restoration in the areas of the oak grove/ savanna and prairie will continue to take place as depicted in the 2024 operations plan. The Appli- cant has partnered with the non-profit Great River Greening on their reclamation efforts. This spring the two parties will be developing a new work plan for the reclamation efforts. The Applicant also continued treatment of invasive Siberian Elm, Black Locust, and brush species. This treat - ment work took place in the previously reclaimed areas along the eastern perimeter of the site. Nuisance Noise Complaints The Public Safety Department reported that there were no noise complaints related to the 24 -hour mining that occurred in 2023. Honorable Mayor, City Council, and Jennifer Levitt Holcim MWR, Inc. – Annual Mining Permit January 26, 2024 Page 5 of 5 Meeting Notices The meeting notice was mailed to 18 property owners who are within a half -mile of the mine on January 10, 2024. Staff have not received any comments at the time of writing this report. City Department Review Holcim’s 2024 mining permit application was distributed to other City departments. No comments were received. Recommendation That the Council adopt Resolution 2024-016 approving the 2024 Mining Permit for Holcim – MWR, Inc. – Nelson Sand & Gravel Facility.

Budget Implication N/A Attachments 1. Standard Specifications and Detail Plates Updates CC Memo 2. Standard Specifications for 2024 3. Standard Detail Plates for 2024 To: Honorable Mayor and City Council Jennifer Levitt, City Administrator From: Joe Fox, PE, Project Engineer Date: January 29, 2024 Re: Approve Cottage Grove 2024 Standard Specifications for Street & Utility Construction and 2024 Standard Detail Plates Background The documentation for every city construction project and private residential development project includes standard specifications and detail plates. These documents lay out the city’s construction and contracting requirements and help ensure uniformity in the design and con- struction of public and private projects. In December of 2018, the Engineering Department drafted complete standard specifications for construction and revised standard detail plates. The standard specifications and standard detail plates were approved by the City Council in March of 2018 and have been updated annually since 2020. Discussion Standard Specifications Prior to the development of the standard specifications in 2018, separate specification docu- ments were created by the city’s design consultant for each public infrastructure project. For residential development, where infrastructure is designed and constructed privately, extensive city plan review was required. Due to the length and complexity of a project specification doc- ument, a large amount of coordination and review was required prior to 2018 to ensure private residential project specifications met city standards. This resulted in additional costs to devel- opers and additional time to design a development. The standard specification document sim- plifies this process by giving a developer’s engineer a preapproved specification to utilize. This simplifies the plan approval process for developers, city staff, and consultant engineers. Recently city staff updated the standard specifications again to remain in conformance with applicable industry standards and MnDOT Standard Specifications as we embark on the 2024 construction season. A handful of minor changes were made based on items that have been identified through the past construction season. Standard Detail Plates Historically, the city has maintained a book of standard det ail plates, which are used in con- struction plans to detail typical construction requirements. A few examples are the city stand- ard bituminous street section; catch basin with sump; and construction requirements related to various city utilities. The city standard detail plates have been updated to be consistent with the revisions to the standard specification document and are enclosed for approval. Honorable Mayor, City Council, and Jennifer Levitt Approve 2024 Cottage Grove Standard Specifications for Street & Utility Construction and 2024 Standard Detail Plates January 29, 2024 Page 2 of 2 Recommendation It is recommended that the City Council approve the Cottage Grove 2024 Standard Specifica- tions for Street & Utility Construction and 2024 Standard Detail Plates.

The concrete shall be fresh and extend to undisturbed (freshly cut) trench wall. C. On the smaller sizes of pipe, up to and including 4 inch pipe, the construction of horizontal thrust blocks requires only the simplest of forms; the stiff concrete is shaped to block a wedge with its widest part against the solid trench wall; larger blocks require some form of construction at the sides and the top to achieve proper bearing area with a minimum amount of concrete. In a stable clay soil, a 4 inch line will require 2 square feet of bearing area, a 6 inch pipe will require 6 square feet of bearing area and a 10 inch pipe will require 16 square feet of bearing area. D. If the ground is too soft to provide proper support for the thrust block, the Contractor will furnish and install clamps and tie rods for the retainment of the fitting. 3.09 BACKFILLING A. Initial Backfilling 1. Selected fill dirt or sand shall be used for backfill if soil is rocky. If rocky subsoil conditions are encountered, the trenching depth should be 2 inches below normal depth to allow for proper bedding. IRRIGATION SYSTEM © 2024 City of Cottage Grove, Minnesota 32 80 00 - 9 2. The initial backfill will always be done by hand and shoveled in evenly along both sides of the pipe and hand tamped into place. Care will be exercised to insure the soil does not bridge and fail to go under the pipe. Next, another layer will be shoveled in and tamped to provide a 4 inch to 6 inch cover over the pipe. 3. The excavated area around the sprinkler risers and sprinkler heads shall be backfilled by hand with select material free of large rocks, roots or foreign debris. If, in the opinion of the Engineer or the Owner, the excavated material is not suitable for use in backfilling, the Contractor shall furnish clean, fine sand for that purpose from an off-site source at no expense to Owner. B. Final Backfilling 1. After the wiring has been installed and examined by the Owner, the trench shall be carefully backfilled with excavated materials approved for backfilling. The remaining backfill shall contain no lumps or rocks no larger than 3 inches. The top 6 inches of backfill shall be good topsoil, acceptable to the Owner and shall be free of lumps, rocks, subsoil, and trash. 2. The trenches will be accepted as completed when they are left in a condition to receive sod or seed without further grading. 3. Trench settlements that occur before or during the correction period shall be repaired in a manner acceptable to the Owner at the Contractor’s expense. 4. The Contractor shall remove and dispose of any excess excavated material, rocks, debris continuously as the construction areas are backfilled so as to cause the least possible disruption to the existing turf. 3.10 POP UP SPRINKLERS A. Sprinklers shall be set plumb and level with the turf at the locations called for on the drawings. Elevation of the sprinkler heads is critical and the contractor shall exercise care to set them exactly on grade. B. All threaded fittings shall be OCV screwed malleable, mild iron.

Contents of notice to residents, administrator and Owner. The notice shall specify the days and the hours during which sewer service will be restricted. C. Reminder Notice: A written, or verbal reminder notice shall be delivered at least 48 hours prior to the actual work. 3.03 CONSTRUCTION REQUIREMENTS A. CIPP installation shall be in accordance with ASTM F1216, Section 7, or ASTM F2019, Section 6.4 with the following additional requirements: 1. Resin Impregnation - The quantity of resin used for liner impregnation shall be sufficient to fill the volume of air voids in the liner with additional allowances for polymerization shrinkage and the loss of resin through cracks and irregularities in the original pipe wall. A vacuum impregnation process shall be used. A roller system shall be used to uniformly distribute the resin throughout the liner. 2. Liner insertion shall be performed in accordance with manufacturer's recommendations and in such a way to fully extend the liner to its termination point, hold the liner tight against the pipe wall, and produce dimples at service connections and flared ends at maintenance holes. Lubricants may be used as necessary. Care shall be taken so as not to overstress the felt fiber. 3. Unless otherwise indicated in the plans or authorized in writing by the Engineer, steam curing, water curing, and UV curing shall all be considered as an acceptable cure method for this project: a. Steam Cure: 1) After inversion is completed, suitable steam-generating equipment is required to distribute steam throughout the pipe. 2) The equipment should be capable of delivering steam throughout the section to uniformly raise the temperature within the pipe above the temperature required to effect a cure of the resin. 3) The temperature and pressure maintained in the pipe and the duration of the cure period shall be as recommended by the manufacturer. 4) The curing of the CIPP must take into account the existing pipe material, the resin system, and ground conditions (temperature, moisture level, and thermal conductivity of soil). 5) Cooling: a) The new pipe should be cooled to a temperature below 113 degrees Fahrenheit before relieving the internal pressure within the section. b) Cool-down may be accomplished by the introduction of cool water into the section to replace the mixture of air and steam being drained from a small hole made in the downstream end. c) Care shall be taken in the release of head so that a vacuum will not be developed that could damage the newly installed pipe. CURED-IN-PLACE PIPE (CIPP) GRAVITY © 2024 City of Cottage Grove, Minnesota 33 01 38 - 9 b. Circulated Heated Water Cure: 1) After inversion is completed, suitable heat source and water recirculation equipment are required to circulate heated water throughout the pipe. 2) The equipment should be capable of delivering hot water throughout the section to uniformly raise the water temperature above the temperature required to effect a cure of the resin. 3) The heat source should be fitted with suitable monitors to gauge the temperature of the incoming and outgoing water supply. Another such gauge should be placed between the impregnated tube and the pipe invert at the termination to determine the temperatures during cure. 4) The temperature and pressure maintained in the pipe and the duration of the cure period shall be as recommended by the manufacturer. 5) The curing of the CIPP must take into account the existing pipe material, the resin system, and ground conditions (temperature, moisture level, and thermal conductivity of soil). 6) Cooling: a) The new pipe should be cooled to a temperature below 100 degrees Fahrenheit before relieving the static head in the inversion stand pipe. b) Cool-down may be accomplished by the introduction of cool water into the inversion stand pipe water to replace hot water being drained from a small hole made in the down-stream end. c) Care shall be taken in the release of head so that a vacuum will not be developed that could damage the newly installed pipe. c. UV Cure – Follow ASTM F2019, Section 6.6 & 6.7: 1) The approved system must utilize an outer and inner film to ensure that the liner remains intact during the insertion process and to protect the resin at all times during the installation and curing process from water and debris contamination and resin migration. 2) A winch should be used to pull the glass fiber liner into position in the pipe. The pulling speed shall not exceed 15ft/min. The liner shall have a lateral fiberglass reinforcement band which runs the entire length of the liner ensuring that the pulling force is transferred to the band and not the fiberglass liner. Once inserted, end plugs shall be used to cap each end of the glass fiber liner to prepare for pressurizing the liner. As with all CIPP products liner restraints should be used in manholes. 3) A slip sheet shall be installed on the bottom one third to one half of the pipe prior to liner insertion, for the purpose of protecting the liner during insertion and reduce the drag, or as recommended by the liner manufacture. 4) The glass fiber liner shall be cured with UV light sources at a constant inner pressure. When inserting the curing equipment in the liner, care should be taken to not damage the inner film material. 5) The UV light sources should be assembled according to the manufacture’s specification for the liner dimeter. For the liner to achieve the required water tightness and specified mechanical properties, the following parameters must be controlled during the entire curing process, giving the Engineer a record of the curing parameters over every segment of the entire length of the liner. This demonstrates that the liner is cured properly. The recording will include: a) Curing Speed b) Light Source and Wattage CURED-IN-PLACE PIPE (CIPP) GRAVITY © 2024 City of Cottage Grove, Minnesota 33 01 38 - 10 c) Inner Air Pressure d) Curing Temperatures e) Date and Time f) Length of Liner This will be accomplished using a computer and data base that are tamper proof. During the curing process, infrared sensors will be used to record curing data that will be submitted to the Engineer with a post CCTV inspection on the portable hard drive. 6) The optimal curing speed, or travel speed of the energized UV light sources, is determined for each length of liner based on internal diameter, liner thickness, and exothermic reaction temperatures. 7) The inner film material should be removed and discarded after cuing to provide optimal quality of the final product. B. The liner pipe shall be continuous, without joints over the entire length of the pipe. The liner shall be free of all visual and material defects, including but not limited to foreign inclusions, dry spots, pinholes, and delaminations. The surface shall be smooth and free of waviness throughout the pipe. C. Any defects that will affect the structural integrity or hydraulic capacity of the reconstructed pipe shall be repaired or the liner shall be replaced at the Contractor's expense, including large radial or longitudinal wrinkles that occur in such a size as to reduce the thickness or nominal diameter of the finished CIPP product. D. Hydrophilic end seals are required to seal the ends of each CIPP liner as it connects to the manhole. These seals will be installed prior to CIPP to prevent water tracking between the CIPP product and the existing host pipe. End Seals shall be LMK Insignia Seals, Trelleborg Liner End Seal or Engineer approved equal. 3.04 REINSTATEMENT OF SEWER SERVICE LATERALS A. The Contractor shall certify he has a minimum of two complete working cutter units plus spare key components on the site before each inversion. B. Prior to installing the sewer liner (during the television process), the Contractor shall locate, dye- test and record the location of all sewer lateral connections that are in question. The Contractor shall immediately submit this information to the Owner. The Owner will then determine which, if any, sewer services are to be abandoned. Those services designated to be abandoned will not be reinstated. C. After the sewer lining is complete, the Contractor shall re-establish all service connections except those designated by the Owner to be abandoned. This shall be done without excavation from the interior of the pipe by means of a television camera and a remotely controlled cutting device. 1. If the Contractor is unable to re-establish the service connection from inside the pipe and excavation is necessary, no additional payment will be made for excavations for the purpose of reopening connections and the Contractor will be responsible for all costs and liability associated with such excavation and restoration work. CURED-IN-PLACE PIPE (CIPP) GRAVITY © 2024 City of Cottage Grove, Minnesota 33 01 38 - 11 2. Reestablished service connections shall be clean and smooth, free of jagged edges and conform as closely as possible to the dimension of the existing service. 3. Brush style cutters or similar device will be required to ensure that the laterals are smooth for potential CIPP lateral lining. D. The sewer main shall be lined prior to lining service laterals, unless approved otherwise by the Engineer. 3.05 INSPECTION A. CIPP samples shall be prepared and tested in accordance with ASTM F1216, Section 8.1 using either method proposed. B. Leakage testing of the CIPP shall be accomplished during cure while under a positive head. CIPP products in which the pipe wall is cured while not in direct contact with the pressurizing fluid (e.g., a removable bladder) must be tested by an alternative method approved by the Owner. C. Visual observation of the CIPP shall be in accordance with ASTM F1216, Section 8.4. 3.06 TELEVISING A.

Adopt RAISE Grant Resolution Memo 2024-2-7 2. 2024 RAISE Grant Resolution To:Honorable Mayor and City Council Jennifer Levitt, City Administrator From:Ryan Burfeind, Public Works Director Date:February 7, 2024 Re:County 19A/100th Street Realignment – RAISE Grant Application Background In 2019, Washington County began a planning study related to a future arterial roadway to be developed in the southwestern area of the County, within the City of Cottage Grove. The pri- mary driver of this study was to address the lack of arterial roadways in this area of the County. The County worked with several partners on this project including Cottage Grove, St. Paul Park, Grey Cloud Island Township, and the South Washington Watershed District. In April of 2021, the final study was approved by the City Council. Since that time, this southern area of Cottage Grove has seen a rapid acceleration of both industrial and residential development. Due to this, the City and County are working to implement the first phase of the Southwest Arterial Study. This will involve the realignment of County 19A and 100th Street to provide a direct connection from Highway 61 into the Business Park. This project would also include the construction of a bridge over the CP Railroad, which is critical to allow for unhindered access for logistics and distribution businesses. Discussion While preliminary design work has been completed by the County; final design, right-of-way acquisition, and construction costs are not funded at this point. The City and County are working to obtain funding through multiple sources including State and Federal grants, and State Bonding. Along those lines, Cottage Grove is leading the effort to submit a Federal RAISE grant, which stands for Rebuilding American Infrastructure with Sustainability and Equity. This is a very comprehensive and competitive grant, which is due February 28, 2024. As part of the application, a resolution from the City Council is required. A very detailed cost estimate is also needed as part of the grant process. Based on the preferred design alternative that has been selected, the total project cost shown in the grant is $47 million. The City will be requesting the maximum grant award amount of $25,000,000. The City and Washington County Capital Improvement Plans show a combined local cost share of $10,900,000, which will satisfy the 20% local match requirement of $6,250,000. Currently, the local cost share is $6,000,000 from the County and $4,900,000 from the City. The remaining funds are being requested through state bonding. Recommendation It is recommended that the City Council adopt Resolution 2024-020 supporting the City’s RAISE grant application for the County 19A/100th Street Realignment Project. CITY OF COTTAGE GROVE, MINNESOTA CITY COUNCIL RESOLUTION 2024-020 A RESOLUTION AUTHORIZING THE CITY TO APPLY FOR THE RESTORING AMERICAN INFRASTRUCTURE THROUGH SUSTAINABILITY AND EQUITY (RAISE) GRANT Whereas, the City of Cottage Grove is seeing incredible growth and modernization; and Whereas, with such rapid growth, it has been a challenge for the City to replace aging infrastructure, address increasing traffic congestion, and improve safety all while encouraging a robust period of diverse population growth and job growth; and Whereas, a 2019 study conducted by Washington County (the “Study”) documented a lack of roadways specifically serving an area of growing industrial and residential development near Jamaica Avenue and Trunk Highway 61, a pivotal intersection for the community and region; and Whereas, the Study recommended the solution to congestion and safety concerns is the construction of a new arterial roadway that would also require the realignment of the existing 100th Street and County Road 19A, the intersection reconstruction of County Road 19A and Trunk Highway 61 and the construction of a railroad bridge to provide a grade- separated crossing over Canadian Pacific’s rail line (hereinafter referred to as the “Southwest Arterial Project”); and Whereas, the Southwest Arterial Project will serve as the main transportation route to Trunk Highway 61 from this growing area of the community, will greatly reduce congestion, increase capacity, and relieve stress at the Jamaica Avenue and Highway 61 interchange and also provide a much-needed additional access point to the City’s Industrial Park; and Whereas there has been unprecedented new growth in the City’s Industrial Park, including the new NorthPoint Development, a 3.4 million square foot industrial park that will bring 1,800 jobs to the community, and by Renewal by Anderson which completed a 330,000 square foot expansion, and two additional distribution center projects totaling 366,000 square feet; and Whereas, the residential development in this same area is also seeing the extraordinary growth of several potential development projects by 2025 that will total nearly 1,000 additional residential units and include a variety of housing stock and affordability tiers with single-family lots, smaller lots for active adults, townhomes and apartments; and Whereas, the Southwest Arterial Project is both locally and regionally significant as it is directly improving the access to the main thoroughfare of Trunk Highway 61 that connects the City of Cottage Grove northerly to the Twin Cities Metro Area as well as to the southern regions of the State; and Whereas, this critical corridor is essential to the mobility of the City’s workforce, supply chain industries, and future bus transit investments; and Whereas, by reducing traffic congestion and increasing safety, the Southwest Arterial Project will have a substantial and immediate impact by providing efficiencies in mobility, accessibility and connectivity to travelers, residents, workforce, and industries; and Whereas, the Southwest Arterial Project is an innovative project in collaboration with other governmental agencies who all seek to increase workforce development opportunities, create community connectivity, and remove barriers to opportunity; and Whereas, there are significant funding obstacles to design, construct and realize the Southwest Arterial Project, which has an estimated total project cost of $47,000,000; and Whereas, the Metropolitan Council recognized the regional significance of the Southwest Arterial by awarding in $7,000,000 in PROTECT Program formula funding; and Whereas, based on the estimated total project cost and the maximum $25,000,000 grant award, the City must provide a 20% match in the amount of $6,250,000; and Whereas, the RAISE Grant, which seeks to provide funding for projects of universal design and accessibility for travelers, increase mobility, and remove barriers to economic opportunity is a perfect match for the Southwest Arterial Project’s purposes and goals by meeting the transportation needs of growing and diverse community and expansion of the City’s industrial mobility-related businesses; and NOW THEREFORE BE IT RESOLVED, the City Council of the City of Cottage Grove, in partnership with County of Washington, State of Minnesota, that the City is hereby authorized to apply for and execute the necessary documents for the RAISE Grant application to request funding for the Southwest Arterial Project; and Be it further resolved that if so awarded, the City will honor the local contribution requirements and any unforeseen contingencies to meet the full funding needs for the Southwest Arterial Project, and the City will honor the program requirements of meeting a funding agreement by September 30, 2028 and full expenditure of funds by September 30, 2033.

CR 74 Maintenance Agreement To: Honorable Mayor and City Council Jennifer Levitt, City Administrator From: Crystal Raleigh, PE, Assistant City Engineer Date: January 30, 2024 Re: Approve Construction Cost Share & Maintenance Agreements with Washington County for the County Road (CR) 74 Multi-Use Trail Project Background The City of Cottage Grove is working cooperatively with Washington County on the County Road 74 Multi-Use Trail Project. This project will extend a trail along the south side of County Road 74 (65th Street) from Meadow Grass Avenue to Hadley Avenue. As part of the project, construction cost share and maintenance agreements with Washington County will need to be executed. Discussion Cooperative Agreement for Construction Cost Share This cooperative agreement for construction outlines the cost participation for construc- tion, and contract administration costs. City construction costs for the project are deter- mined through Washington County’s construction cost participation policy. The City’s construction cost share is estimated at $5,643, with a total project cost estimated at $284,560. The City is also responsible for construction engineering and observation costs esti- mated at $3,642. These breakdowns and the cost share policy are consistent with pre- vious City/County cooperative projects. In total, the City’s cost share is estimated at $9,285, and these numbers are based on the final engineering estimate and will be updated with actual costs once bids are received. Cooperative Agreement for Maintenance The cooperative agreement for maintenance outlines the agency responsibilities for fu- ture maintenance of the improvements to be constructed as part of this project. Per this agreement, the City is allowed, but not required, to perform snowplowing on trails and additional mowing of boulevards within County right-of-way. These conditions are consistent with past maintenance agreements with Washington County. Recommendation It is recommended the City Council: Honorable Mayor, City Council, and Jennifer Levitt Approve Construction Cost Share and Maintenance Agreements with Washington County – CR 74 Trail January 30, 2024 Page 2 of 2 1.

Meeting Date 2/7/2024 Department Public Works Agenda Category Action Item Title 2024 Mill and Overlay Project – Approve Plans and Specifications and Establish Bid Date Staff Recommendation Adopt Resolution 2024-018 approving the plans and specifications and establishing a March 7, 2024, bid date for the 2024 Mill and Overlay Project. Budget Implication $1,408,000 - Roadway Maintenance Fund, Utility Funds, St. Paul Park Cost Share Attachments 1. Mill and Overlay CC Memo 2. Mill and Overlay Resolution 3. Mill and Overlay Plans and Specs To: Honorable Mayor and City Council Jennifer Levitt, City Administrator From: Amanda Meyer, PE, City Engineer Genevieve Tester, Graduate Engineer Date: January 24, 2024 Re: 2024 Mill and Overlay Project – Approve Plans and Specifications and Establish Bid Date Background The proposed work for the Mill and Overlay Project in 2024 is to resurface streets in the final phase of the three-year Thompson Grove neighborhood road rehabilitation plan , including a 0.15- mile section of 85th Street that extends west into St. Paul Park. This program focuses on replacing the top layer of pavement to lengthen the life cycle of the roadway. As projects are completed, any necessary ADA improvements to bring existing pedes - trian infrastructure into compliance would be addressed as well. These improvements would not be assessed to the adjacent property owners; the Roadway Maintenance Fund will be used for this project. Discussion Summary of Road and Infrastructure Improvements: The proposed Mill and Overlay project for 2024 includes roadways in the Thompson Grove neighborhood as shown in the below image. The rehabilitation method proposed is to remove the top layer of existing asphalt surface and replace it with a new surface. The distresses observed in the pavement point to a failing top layer of pavement, though the bottom layer of pavement and the base below the pavement are still structurally sound. Replacing the top la yer of pavement will help to increase the lifecycle of the road; it is common with a mill and overlay project that any cracking of the roadway that has ex- tended to the base layer will typically reflect through the new pavement within the first year. Minor spot curb replacement, utility repairs, and ADA improvements will also be completed as part of the project. If the project moves forward, additional information will be provided to neighborhood residents prior to construction. The 2024 project will include approximately 5.0 miles of streets in the Thompson Grove neighbor- hood. Proposed streets extend west from Grange Boulevard to the southeast city limit of St. Paul Park. Plans and Specifications: Plans and specifications have been prepared in accordance with City standards and specifications. The engineer’s estimate for construction of the project is $1,408,000. St. Paul Park will be responsible for the cost associated with the portion of the project that is within their city limits as noted in the background. Bid Date: A bid date of March 7, 2024, at 10:00 a.m. will provide ample time to provide required notification to contractors. Recommendation It is recommended the City Council adopt Resolution 2024-018 approving the plans and specifi- cations and establishing a March 7, 2024, bid date for the 2024 Mill and Overlay Project. CITY OF COTTAGE GROVE, MINNESOTA CITY COUNCIL RESOLUTION 2024-018 RESOLUTION APPROVING THE PLANS AND SPECIFICATIONS AND ESTABLISHING A BID DATE FOR THE 2024 MILL AND OVERLAY PROJECT WHEREAS, plans and specifications have been prepared in accordance with the City Standards and Specifications for the 2024 Mill and Overlay Project; and WHEREAS, a bid date has been established for March 7, 2024; and WHEREAS, the City Engineer has presented such plans and specifications to the City Council for approval.

Feasibility Reports allow staff to review areas in further detail to better understand the current state, needs, and economic feasibility of the proposed areas. As noted during the Council workshop, staff understood that with the addition of Jamaica Avenue from 80th Street to 90th Street, there would not be sufficient funding to complete all of the roadways that were identified as part of authorizing the feasibility report. On January 3, 2024, a workshop was held with Council to discuss findings of the field review of the proposed project areas. After taking cores and evaluating the areas further, it was determined that the roadways in the Thompson Grove Estates neighborhood had enough structural stability to last another three to five years. Staff walked through three possible project area scenarios with Council and were provided direction to move forward with the following area to be included in the 2024 Pavement Management project: • Prestige Estates Neighborhood (1st & 2nd Additions and Prestige Estates on the Park): Streets include Jenner Avenue from 80th Street to Jocelyn Avenue; Jocelyn Avenue from 80th Street to Jenner Avenue; and 79th Street from Jocelyn Avenue to Jocelyn Avenue. The Prestige Estates roadways listed above are 29 to 34 years old. They were recently examined in a variety of ways to determine their condition as part of the Feasibility Report process. Pavement cores were drilled and extracted in selected areas to analyze bituminous and aggregate thickness and the structural condition of the pa vement section, and Ground Penetrating Radar (GPR) testing was performed. In a 2023 visual inspection of Prestige Estate, the roadways showed extensive cracking, raveling, and continuous patching. The pavement cores showed asphalt stripping and severe degradation. The GPR provided more thorough data on the pavement thickness profile throughout the neighborhood. Excessive cracking was noted on road surfaces that would typically reflect through within a year if a mill and overlay project were completed at this time. The curb and gut ter are in poor condition with approximately 40 percent of curb requiring replacement. Honorable Mayor, City Council, and Jennifer Levitt 2024 Pavement Management January 30, 2024 Page 2 of 3 As with previous pavement management projects, utilities within the project limits were exam ined for necessary maintenance. Overall, the utilities were found to be in good condition, but some maintenance work is required. The top sections of sanitary and storm manhole structures will be upgraded to meet current City standards, corroded valves will be replaced as necessary, hydrants will be reconditioned and repainted as necessary, and concrete hydrant pads will be installed. Additionally, the condition of street light infrastructure was evaluated, and some improvements are proposed. A special benefit appraisal was completed in accordance with the City’s policy for those properties with direct access to the streets included in the project area. A neighborhood meeting was held on January 30, 2024 to discuss the various improvements proposed, the findings of the special benefit appraisal, and the proposed assessments. Discussion Summary of Road and Infrastructure Improvements: The rehabilitation method proposed for the residential roadways in the Prestige Estates 1st, 2nd, and Prestige Estates on the Park Ad- ditions is to remove the existing asphalt surface and replace it with a new surface. This new sur - face will consist of two lifts of bituminous totaling 3.5 inches of pavement. Full curb replacement throughout the area will also be completed. Finally, minor utility improvements for sanitary sewer, water, stormwater, and lighting systems will also be included. The total estimated project cost for the neighborhood is $1,170,018.26. Assessments for this project will be based on the “Infrastructure Maintenance Task Force Spe cial Assessment Policy for Public Improvements,” dated September 30, 2005, revised October 31, 2023. The feasibility report recommends that all properties adjacent to the Prestige Estates project be assessed. The policy allows 45 percent of adjacent costs to be assessed to residential properties. The estimated assessment for the Prestige Estates improvements listed above based on the City’s Assessment Policy is $6,647.65 per residential building lot equivalent (RBLE). Single-family residential is assessed at a rate of 1.0 of the RBLE. The special benefit appraisal that was completed showed a benefit of $7,500 per residential unit, which supports the proposed assessment. Project Funding Analysis: As noted above, the total estimated project cost for the street and utility work in the Prestige Estates neighborhood is $1,170,018.26. According to the City’s policy, 45 percent of the total project cost for road work and utilities is assessed against the benefiting residential properties. As such, the improvements in the Prestige Estates 1st, 2nd, and Prestige Estates on the Park Additions would be assessed following this policy. The total project value that is assessed is $525,164.19. The remainder of the project costs are proposed to be funded through utility funds and the general levy. The Cost Estimate Summary can be viewed in Appendix B of the Feasibility Report. Honorable Mayor, City Council, and Jennifer Levitt 2024 Pavement Management January 30, 2024 Page 3 of 3 Project Option Discussion Option #1: Order the Prestige Estates project as outlined in the feasibility report. Total estimated project cost – $1,170,018.26 Total anticipated assessments – $525,164.19 The benefit of proceeding with the project is that soliciting for bids this winter will provide a stable bidding environment, which reduces the burden to the general taxpayers and the residents adja - cent to the project who are paying assessments. Another result of the new pavement is reduced maintenance costs associated with the streets in the project area. Those maintenance dollars and resources can then be reallocated to other parts of the community, which is a greater benefit to the general taxpayer. There are also similar benefits related to the repairs to the utilities in the project area. The CIP outlines a fiscally responsible plan to rehabilitate roads and utilities within the community. By ordering the project, those plans stay true to that document and the Council’s direction given in the development of the CIP. Option #2: Do not order the project as outlined in the feasibility report. If the improvements related to the 2024 Pavement Management Project are not ordered, the roads will continue to deteriorate, which will result in increased maintenance costs. Those costs are borne by all taxpayers, not just the property owners that live on those streets. Future project costs will also be increased by 2.5 percent to 8 percent annually as a result of the construction index. When a pavement management project is delayed, it creates a domino effect by delaying all future pavement management projects. The cost of the domino effect is hard to capture, since there are pavement management projects planned each year into the future. The City’s approach since 1994 has been to ensure a safe condition and preserve the structural integrity of roads in a fiscally responsible manner. Independent third-party benefit appraisals conducted since 2007 have con - cluded that this program improves property values within the project areas, as compared to the existing deteriorated condition.

Discount Tire Resolution TO: Honorable Mayor and City Council Jennifer Levitt, City Administrator FROM: Conner Jakes, Associate Planner DATE: January 29, 2024 RE: Proposed Discount Tire Facility at 8647/8649 East Point Douglas Road South – Conditional Use Permit Introduction Halle Properties, LLC (Applicant) has submitted an application for a Conditional Use Permit (CUP) at 8647/8649 East Point Douglas Road South. The Applicant is proposing to utilize the existing building and site layout for a minor automobile repair use onsite. The proposed project is located on a .98-acre parcel of land to the southwest of the current Wendy’s restaurant and northwest of the current Target site. Site Location Review Schedule Application Received: December 12, 2023 Application Accepted: December 12, 2023 Planning Commission Meeting: January 22, 2024 City Council Meeting: February 7, 2024 60-Day Review Deadline: February 10, 2024 Honorable Mayor, City Council, and Jennifer Levitt Proposed Discount Tire Facility at 8647/8649 E. Pt. Douglas Rd. S. January 29, 2024 Page 2 of 7 Planning Commission The Planning Commission reviewed the Conditional Use Permit request at their January 22, 2024, meeting. The Commission asked for clarification on the following: • The previous use was an automotive repair use, which is the same as the proposed use. Why is a Conditional Use Permit required? o Staff stated at the time the parcel was originally developed the site was zoned B -3, which permitted automotive repair uses by right. The parcel is now zoned Mixed Use and a minor automotive repair use is permitted with a Conditional Use Permit. To align with current standards, a Conditional Use Permit is required. No residents participated in the public hearing. The Planning Commission unanimously (6-to-0 vote) recommended approval of the application. Background The subject site has been occupied by an automotive repair use since the original approvals in 1991 and was most recently occupied by Big O Tires. In 1992 an application for a simple lot division was submitted and approved. The intent at the time was to create two parcels allowing the user to separate the automotive use from potential office space for additional tenants. How - ever, the entire site has been most recently occupied by one tenant and the only onsite use was automotive repair. Approvals for an automobile car wash were granted in March of 2023; however, the applicant for the automobile car wash withdrew the application. A condition of approval will require the two lots be combined into one lot. 2022 Aerial Photo Honorable Mayor, City Council, and Jennifer Levitt Proposed Discount Tire Facility at 8647/8649 E. Pt. Douglas Rd. S. January 29, 2024 Page 3 of 7 Proposal The Applicant is proposing to utilize the existing building and site layout for a minor automotive repair use with updates to the architectural elevations, parking lot stalls, and site landscaping. Daily activities onsite include only the selling, installing, and servicing of tires and wheels. The re will not be automotive repair, oil changes, or any body work occurring onsite as the focus of the business is solely on tires. The proposed hours of operation are Monday through Friday from 8 :00 a.m. to 6:00 p.m., and Saturday from 8:00 a.m. to 5:00 p.m. Proposed Site Plan Planning Considerations Zoning and Comprehensive Plan The subject site is zoned MU, Mixed-Use District, and is guided as Mixed Use in the 2040 Com- prehensive Plan. The proposed use is consistent with the City’s zoning ordinance and land use plan. Minor automobile repair uses are permitted with a Conditional Use Permit (CUP) within the Mixed-Use Zoning District. Conditional Use Permit City Code requires a CUP for a minor automotive repair use within the Mixed -Use District. The Applicant is proposing to operate a minor automotive repair use solely focused on selling, in - stalling, and servicing tires. The criteria for issuance of a CUP are as follows: 1. The proposed use shall be consistent with the Comprehensive Plan. 2. The proposed use shall not negatively impact the health, safety and general welfare of occupants of surrounding lands. Honorable Mayor, City Council, and Jennifer Levitt Proposed Discount Tire Facility at 8647/8649 E. Pt. Douglas Rd. S. January 29, 2024 Page 4 of 7 3. Adequate public facilities and services shall be able to be provided to the site where the use is proposed, and/or existing infrastructure shall be able to absorb the additional demand for public services such as utilities, streets, parks, schools, etc. 4. Incompatible impacts of the proposed use shall be screened and buffered from adjacent property and the surrounding neighborhood. The City Council may require additional landscaping or screening above that required in the Zoning Code. 5. The site or building associated with the proposed use meets or exceeds the architec - tural design and landscaping standards for the district in which it is located. The City Council may require additional architectural standards above those required in the Zoning Code. 6. The use is consistent with the purposes of the Zoning Code and the purposes of the zoning district in which the applicant intends to locate the proposed use. 7. The generation and characteristics of traffic associated with the use and its impact on traffic volumes and safety associated with driveway locations, existing and proposed capacity on adjacent roads, sidewalks, and trail connections can be adequately mitigated. 8. Floodplain standards shall follow City Code Title 11, Chapter 10. Upon review of the application, the proposed use meets the forementioned criteria. Parking City Code Title 11-3-4 states that auto repair uses require 3 parking stalls per auto bay, plus 1 parking stall per employee. The Applicant has indicated a total of 4 auto bays and staffing of 15 employees; therefore, the minimum number of required stalls is 27. The proposed site plan indi- cates a total of 38 parking stalls, thus meeting the minimum required number of stalls. The existing parking lot layout consists of 34 total stalls. The Applicant is proposing to restripe the parking lot, which will result in an increase in the number of stalls by 4. This is due to the change of diagonal stalls to straight stalls along the northeastern property line. Proposed Site Plan with Updated Parking Stall Striping Honorable Mayor, City Council, and Jennifer Levitt Proposed Discount Tire Facility at 8647/8649 E. Pt. Douglas Rd. S. January 29, 2024 Page 5 of 7 Architecture The Applicant is proposing to utilize the existing building but will provide minor architectural ele - vation updates. These updates include new paint, trim, and an updated storefront with a metal canopy overhang. Southwest Building Elevation Northeast Building Elevation Southeast Building Elevation Northwest Building Elevation Landscaping The Applicant is proposing to utilize the existing site layout but has submitted a detailed landscape plan. The plan indicates the planting of 35 shrubs, 21 ornamental grasses, and 21 perennials. In addition, the Applicant has indicated the intent to preserve existing trees onsite that are in good health. Honorable Mayor, City Council, and Jennifer Levitt Proposed Discount Tire Facility at 8647/8649 E. Pt. Douglas Rd. S. January 29, 2024 Page 6 of 7 Landscape Plan Utilities The subject property is located within the Metropolitan Urban Service Area (MUSA). The property is already connected to City utilities and no changes are being proposed for utility connections on the site. Surface Water Management/Grading The site is currently graded to meet the surface water management requirements established by the State, Watershed District, and the City’s Surface Water Management Plan. No changes are proposed to site grading or site imperviousness therefore changes to s ite stormwater manage- ment are unnecessary. Development Fees All applicable development fees have been paid at the time of original development; therefore, no additional development fees are required as part of this proposal. Public Hearing Notices The public hearing notice for the January 22, 2024, Planning Commission meeting was published in the Saint Paul Pioneer Press and mailed on January 10, 2024, to 13 property owners that are within 500 feet of the proposed project. Staff has not received any comments at the time of writing the report. Honorable Mayor, City Council, and Jennifer Levitt Proposed Discount Tire Facility at 8647/8649 E. Pt. Douglas Rd. S. January 29, 2024 Page 7 of 7 Recommendation That the City Council adopt Resolution 2024-017 approving the Conditional Use Permit for a minor automotive repair use to be located at 8647/8649 East Point Douglas Road South. Attachments − Narrative − Architectural Elevations − Engineering Plans November 1, 2023 On behalf of Halle Properties, L.L.C., R.A. Smith, Inc. is pleased to present the attached material for a Conditional Use Permit for a Discount Tire store to be located at 8647 & 8649 East Point Douglas Road South. A Conditional Use Permit is required for the operation of a tire store. The exiting building is a former Big O’s tire store, roughly 9,212 square feet in size. Discount Tire proposes to reimage the building to its current corporate standards. New signage, fresh coat of paint on the exterior and considerable work on the interior. New tire storage will be indoors via a racking system adjacent to the service bays. Used tire storage is segregated in its own storage area and no tires are stored outside. Generally new tires are delivered twice a week via a tractor trailer, and used tires are removed twice a week by a local recycling contractor using a box truck. Discount Tire only sells, installs and services tires and wheels. No automotive repair, oil changes or body work is ever done at a Discount Tire location. The focus is solely on tires, wheels and world class customer service. As a benefit to the general public, this store will provide complimentary air checks for any driver who pulls in and requests the service. This location that Halle Properties has selected meets their internal site selection criteria and will be complimentary to nearby commercial developments. With limited business hours and low traffic volumes, open Monday to Friday from 8 AM to 6 PM and Saturday from 8 AM to 5 PM, it’s anticipated that the proposed store will not have a negative impact on traffic. Staffing for this store is typically 6-8 sales/managerial and 8-12 technicians, with the busiest shifts being on Friday and Saturday. The site is designed to accommodate employee vehicles as well as those of customers dropping their vehicles off for service and those who elect to wait to have their tires installed. At your convenience, R.A. Smith will be more than happy to answer any questions or comments.

Budget Implication N/A Attachments 1. Police Use of Force Workshop 01.29.2024 To: Honorable Mayor and City Council Jennifer Levitt, City Administrator From: Peter J Koerner, Director of Public Safety Date: January 29, 2024 Subject: WORKSHOP - POLICE ANNUAL USE OF FORCE REPORT Introduction The Cottage Grove Police Department is proudly and boldly leading police reforms by adapting to evolving community expectations and implementing best practices. Furthermore, CGPD is dedicated to professionalism, transparency, and accountability. We continuously strive to improve services, safety, and trust. We accomplish these goals with a comprehensive approach to use of force review and analysis, training, reporting, and community input. In 2019, CGPD implemented a progressive use of force review policy which mandates that every use of force incident is reviewed, data is collected and analyzed, and an annual report is presented. Each use of force incident is reviewed by our Use of Force Review & Training Committee. Each incident is examined for opportunities to improve our decisions, tactics, policy, and equipment. Use of force data, along with law and nationally recognized best practices, drives our training, tactics, policy development, and equipment acquisitions. The annual use of force report identifies trends in use of force data along with training, equipment, and policy recommendations. The annual report is presented to the Chief of Police, Council, and community stakeholders providing an opportunity to inform and solicit input. Presentation Deputy Director Brad Petersen and Sergeant Nicholas Bailey will present the annual use of force report. Additionally, they will present an abbreviated annual SWAT report.
