Lc�t ares; 5�000 square feet Lot width 75 feet Front yard 30 feet Rear yard 35 feet Side yard 10 feet Side yard, garage 5 feet Maximum structure height 30 feet R3 Development Performance Standards The setback relationship of the new and existing homes adjacent to the project was one of the queries at the neighborhood meeting. The following detail identifies the distances from the pro- posed house pad areas to the existing homes and detached accessory structures (garages). s, 4 Density The density of the proposed development is 2.32 units per acre. The density range for the Low Density Residential Land Use District is one to four dwelling units per acre. Planning Staff Report — Case No. PP2018-009 Hamlet Heights Preliminary Plat February 26, 2018 Page 6 of 18 Lot Sizes The average lot size in the development is 14,854 square feet. Public Utilities The property is currently located in the Metropolitan Urban Service Area (MUSA) and has public utilities available for service connection. The Engineering memo dated February 15, 2018, ad- dresses the utility comments for the project. A Sewer Availability Charge (SAC) will be required to be paid for each lot in the subdivision at the time of building permit. The current SAC rate is $2,485. Environmental Assessment Worksheet (EA W) The proposed project is below the lot count threshold that would trigger an environmental review prior to development. Transportation The project is located on the southern portion of Hamlet Avenue that is located within the Thompson's Grove 5th Addition subdivision. The road was originally platted as a through street in 1959 and has functioned as a pseudo cul-de-sac for the 14 residents along the stub street since the platting of the public right-of-way. Many long-term residents live on the existing Hamlet Avenue stub street. Traffic generation from the project is not any different from other new or ex- isting single family residential development, which is 9.57 trips per day or 230 trips for the new residents and 134 trips for the existing homes. The adjacent roadway network was designed to accommodate residential traffic of this quantity and scale and will not be negatively impacted. The proposed local roads are consistent with the existing roadway in the neighborhood with a road width of 32 feet face -of -curb to face -of -curb. The preliminary plat does not have platted landscaped islands in the cul-de-sac since the sur- rounding area does not have them. Surface Water Management A component of the project will be the removal of the temporary holding ponds from the site, and the incorporation of the management of the existing stormwater runoff into the design of the pro- ject. The stormwater design for the project includes offsite ponding on a portion of Hamlet Park on property owned by the City. The project is outside of the wellhead protection area. The Engi- neering memo dated February 15, 2018, addresses the stormwater comments for the project. An offsite ponding fee in the amount of $107,242 will be required at the time of recording of the plat. Landscaping, one City standard park bench, trash can, and cement pad serving as park amenities will be required in addition to the offsite ponding fee. These amenities should be placed near the junction of the new access trail and the Hamlet Park Trail. Additional stormwater review will be required upon submittal of the final grading and utility plans for the site. Grading The preliminary grading plan was reviewed by Engineering and included in the review com- ments from February 15. Additional grading review will be required upon submittal of final grad- ing and utility plans for the site. Based on concerns about blasting, the applicant will be required to obtain a grading permit, which will need to outline the means and methods for export/import of material and whether blasting is required. If blasting is identified, then a detailed monitoring Planning Staff Report — Case No. PP2018-009 Hamlet Heights Preliminary Plat February 26, 2018 Page 7 of 18 plan will be required. All monitoring and testing for blasting activities and any property damage documented through the monitoring process is the financial responsibility of the developer. Fire Department Access The combined length of the existing and new cul-de-sac length is 1,631 feet. City Code Title 10- 5-3D(1) permits cul-de-sacs greater in length than 600 feet where "by reason of unfavorable land form or the irregular shape of the land, a normal pattern cannot be established, or that land would be underutilized." Staff has identified that this exception is appropriate for this project. Based on the State Fire code, the 38 lots on the existing and new cul-de-sac require a second- ary access for emergency services. The planned trail connections from the development to the existing Hamlet Park Trail has been identified as an acceptable secondary emergency access by the Public Safety Department. The route identified in red below will need be maintained during the winter by the City. z. SIT MqW - MOM h N, - _ - -95th' Street ' i Trails and Sidewalks Based on the lack of sidewalks on the existing roadway, no side- walks will be required for this project. A recreational trail connecting the cul-de-sac with the existing Hamlet Park trailway will be required to be installed by the appli- cant. Based on the Comprehensive Plan, the City is working with the School District to plan a recreational trailway connection linking the new development with District property to the west. 103 RD ST Planning Staff Report — Case No. PP2018-009 Hamlet Heights Preliminary Plat February 26, 2018 Page 8 of 18 It is recommended that the developer shall be responsible for a 50 percent participation responsibility for the linking trail. Final design of the trail will include flexible trail design standards given the terrain deviation at the location. Park Dedication A park dedication fee in lieu of land dedication in the amount of $81,453 will be required at the time of plat recording. Area Charges The area charges for water, sanitary, and stormwater will be required at the time of the plat is recorded. Architecture The detail below identifies several elevation details of the anticipated home styles within the neighborhood. Summary 1) The property is guided for low density residential, and the requested preliminary plat design fits within the parameters of the required density. 2) The property is zoned for Single Family Residential (R-3), and the requested preliminary plat design fits within the parameters of the required development performance standards of the zoning district. 3) The property is within the MUSA and can be properly served by public utilities. Planning Staff Report — Case No. PP2018-009 Hamlet Heights Preliminary Plat February 26, 2018 Page 9 of 18 4) The surface water management of existing and new streets and housing will be properly addressed with this development. 5) The traffic generated from the project will not have negative impacts on the adjacent road- ways. 6) The project is introducing additional builders to the City, thus expanding housing options for stakeholders in the community.

Planning Staff Report — Case No. PP2018-009 Hamlet Heights Preliminary Plat February 26, 2018 Page 15 of 18 57) The City will not have any responsibility with respect to any street or other public im- provements unless the street or other public improvements have been formally accepted by the City. Upon completion of the improvements, the Developer may request, in writing, their acceptance by the City. This request must be accompanied by proof that there are no outstanding judgments or liens against the land upon which the public improvements are located. Upon the City's receipt of a written request for acceptance from the Devel- oper, the City Engineer will conduct a final inspection of the public improvements and will furnish a written list of any deficiencies noted. The City Engineer will base the inspection on compliance with the approved construction plans, profiles and specifications, as re- quired by the city ordinance. Upon satisfactory completion of all construction in accord- ance with the approved plans, profiles, and specifications, as certified by a registered engineer in the State of Minnesota, and receipt of reproducible record drawings and satisfactory test results, the City Engineer will notify the developer in writing of the City's approval of the public improvements and schedule the request for acceptance for review by the City Council. 58) Upon completion of the work, the Developer shall provide the City with a full set of as - built plans for City records and transmitted to the City in a DWG Autocad format and pdf format. Developer must also furnish the City with a pdf format of the final plat and four prints of the recorded plat. If the Developer does not provide as-builts, the City will produce them at the developer's expense. 59) The developer is responsible for completing the final grade on all lots and ensuring all boulevards and yards have a minimum of four inches of organic topsoil or black dirt on them. Placement of organic topsoil or black dirt, sod, and shrubs must not be transferred to homeowners. 60) Notwithstanding any other provision of this resolution to the contrary, the City will issue building permits for up to two (2) model homes on lots acceptable to the City upon Devel- oper's compliance with the following requirements: a. Approval of a building plan and survey by the Chief Building Official. b. Presence of a paved road within three hundred feet (300') and presence of a fire hydrant within one thousand feet (1,000') of the model home(s). c. An unobstructed gravel surface road extension from a paved street surface to the proposed model home's driveway. d. No certificate of occupancy for such model homes shall be issued until all typical requirements for such issuance have been met. e. Final plat has been recorded. f. The Developer acknowledges in the development agreement that prior to the construction of the improvements, site conditions, access to paved roads, and fire hy- drants will be sub -standard and will not be optimized until the improvements are com- pleted. To the fullest extent permitted by law, Developer agrees to indemnify the City, Planning Staff Report — Case No. PP2018-009 Hamlet Heights Preliminary Plat February 26, 2018 Page 16 of 18 its officers, employees, agents and others acting on its behalf and to hold them harm- less and defend and protect them (with counsel of the City's choosing) from and against any and all loss, damage, liability, cost, and expense, specifically including attorneys' fees and other costs and expenses of defense, which result from, or other- wise arise in connection with any actions, claims or proceedings of any sort caused by or arising from the construction or use of the model homes by Developer or its con- tractors, employees, agents, or assigns, prior to the improvements being completed. Such claims shall include, but not be limited to, claims that the model homes could not be accessed properly or in a timely manner by fire equipment and/or police or emer- gency vehicles due to road or site conditions or claims based on lack of proximity to fire hydrants or lack of adequate fire protection. Although indemnification shall cease for claims arising after the improvements are completed and accepted, indemnifica- tion obligations for claims arising prior to the completion of the Improvements shall survive the termination of the agreement. 61) No additional building permits beyond the model permits will be issued until such time as adequate public utilities, including street lights, and streets have been installed and deter- mined to be available to use. The City will require that the utilities, lighting, and street sys- tem have been constructed and considered operational prior to issuance of any building permits in the development. Also, the City must have all the necessary right-of-way and/or easements needed for the property to be serviced. 62) Adequate dumpsters must be on site during construction of streets, utilities, and houses. When the dumpsters are full, they must be emptied immediately or replaced with an empty dumpster. The developer is responsible to require each builder to provide an on- site dumpster to contain all construction debris, thereby preventing it from being blown off-site. 63) Adequate portable toilets must be on-site at all times during construction of utilities, road- ways, and houses. At no time shall any house under construction be more than 250 feet away from any portable toilet. Toilets must be regularly emptied. 64) After the site is rough graded, but before any utility construction commences or building permits are issued, the erosion control plan shall be implemented by the developer and inspected and approved by the City. The City may impose additional erosion control re- quirements if it is determined that the methods implemented are insufficient to properly control erosion. 65) All areas disturbed by the excavation and back -filling operations shall be fertilized, mulched, and disc anchored as necessary for seed retention. Time is of the essence in controlling erosion. If the developer does not comply with the erosion control plan and schedule, or supplementary instructions received from the City, or in an emergency de- termined at the sole discretion of the City, the City may take such action as it deems ap- propriate to control erosion immediately. The City will notify the developer in advance of any proposed action, but failure of the City to do so will not affect the Developer's and the City's rights or obligations. If the developer does not reimburse the City for any costs of the City incurred for such work within thirty (30) days, the City may draw down the letter of credit to pay such costs. Planning Staff Report — Case No. PP2018-009 Hamlet Heights Preliminary Plat February 26, 2018 Page 17 of 18 66) The Developer is responsible for erosion control inspection fees at the current rates. If the developer does not reimburse the City for the costs the City incurred for such work within thirty (30) days, the City may draw down the letter of credit to pay such costs. 67) Dust control measures must be in place to prevent dust and erosion, including, but not limited to daily watering, silt fences, and seeding. The City Engineer may impose reason- able measures to reduce dust at the site. 68) The Developer shall comply with the 1991 Wetlands Conservation Act, as amended. 69) It is the Developer's responsibility to keep active and up to date the developer's contract and financial surety (e.g. Letter of Credit, etc.). These documents must remain active until the developer has been released from any further obligation by City Council motion received in writing from the City Engineer. 70) The Developer must provide to the City an irrevocable letter of credit for on-site improve- ments to ensure that the developer will construct or install and pay for the following: a. Paved streets b. Concrete curb and gutter c. Hard surface driveways d. Street lights e. Water system (trunk and lateral) and water house service stubs f. Sanitary sewer system (trunk and lateral) and sanitary house service stubs g. Storm sewer system h. Street and traffic control signs/signals i.

These improvements are all in conformance with City approved plans and specifica- tions and will be installed at the sole expense of the developer in conformance with City Code Title 10, Chapter 5. p. The bank and form of the security is subject to the reasonable approval of the City. The security shall be automatically renewing. The term of the security may be ex- tended from time to time if the extension is furnished to the City at least forty-five (45) days prior to the stated expiration date of the security. If the required public improve- ments are not completed, or terms of the Development Agreement are not satisfied, at least thirty (30) days prior to the expiration of a letter of credit, the City may draw down the letter of credit. The City may draw down the security without prior notice for any default of the development agreement. The minimum amount for this financial guarantee will be included in the development agreement. 71) The Developer must post a cash escrow with the City's Finance Director to cover engi- neering, legal, and administrative costs incurred by the City. If this non-interest bearing account balance becomes deficient, the Developer must deposit additional funds. This must be done before final bonding obligations are complete. This escrow amount will be included in the development agreement. 72) The Developer must post a cash escrow with the City's Finance Director to cover engi- neering costs and other City services, expenses, and materials provided in reviewing and processing of the final plat, including but not limited to staff time, legal expenses, office and field inspections, general inspections, and all other city staff services performed. This escrow amount will be included in the development agreement. 73) The Developer is responsible for establishing the final grades, topsoil, and seeding of all the residential lots and boulevards within the subdivision. The developer and/or builder is responsible for planting the one boulevard tree per lot and a second boulevard tree on the corner side lot for corner lots after homes are constructed. The City Forester will mark the location where the boulevard tree must be planted and approve the tree species to be planted. The final landscape plan must be coordinated with the City Forester.

Final plans will require plan and profiles of utilities to understand utility cover across the length of pipe, crossings, and clearances between crossings. Sheet 3: 4. Please clarify the source of the existing contours (surveyed, Lidar, etc.). C1-- 5. A 200' transition from the existing 36' (b -b) to new 32'(f -f) street is requested. 6. The existing water tower south of Lot 8 Block 2 should be depicted for clarity. 7. For plowing and maneuverability, construct a 10' radius where bituminous trails intersect. 8. Public Safety is requesting a secondary access to the development. It's requested that a trail be added between lot 1 block 1 and the existing home at 8991 Hamlet Avenue. This trail should be covered by a 20' Outlot and connect to the existing trail in the park. C1 - C. — 9. Lots 1-8, Block 2 rear yard drainage: Bolton & Menk is an equal opportunity employer. Hamlet Heights Preliminary Plan Review Page: 2 a. As depicted the pipe would be difficult for the City to jet and clean (over 500 If) and access is difficult. It is preferred to minimize rear yard storm pipe since access can be difficult in this location. Evaluate the possibility of extending the outlet pipe from the Pine Hill Elementary school basin to Hamlet Ave between lots 5 & 6. In order to reduce pipe in the back yard, evaluate other possible options: i. Extend storm between lots 3 & 4 block 2 to pick up rear structure if needed. Can drainage in rear yards be split up to minimize pipe, while allowing overland drainage across 3-4 lots maximum? For example, can drainage behind lots 4-5 be graded back to CBMH-122 and lots 1-3 go to CBMH-106? 10. Removals don't appear to be depicted clearly, a separate removal plan should be created. For example, it appears that existing trees/brush on the south side of the existing homes appear to be impacted by the proposed grading. 11. The EOF next to lot 1 block 1 of 798.5 should be better defined as it relates to the existing home to the north (8991 Hamlet Ave.). Based on the submitted contours, it appears drainage will encroach on the existing driveway. In order to avoid drainage encroaching on the adjacent property, it may require the low point in the road to be shifted further south. In addition, low openings and finished floor elevations of the existing home should be confirmed as it relates to the proposed drainage. 12. It appears the 793.9 elevation between lots 8 & 9 block 1 is an EOF and should be labeled as such. 13. Label the EOF of the proposed basins to Hamlet Park. 14. Evaluate options to construct the trail off the cul-de-sac at a 5% grade or less. 15. Provide access to all structures adjacent to the proposed ponds with a 10' maintenance bench. It appears a maintenance bench would not be required on the west (home) side of the pond. This should be coordinated with the detail on Sheet 9 as well. 16. Access will be required to the rear yard storm behind lots 7-11 block 1. Consider placing CBMH- 152 and CBMH-162 in the Outlot. CBMH-161 could likely be eliminated. 17. The berm between basins should also be a minimum 10' wide to allow the City access for maintenance. This should be coordinated with the detail on Sheet 9 as well. 18. Provide details as to if site balances or if there is fill intended to be hauled in to grade the site. Sheet 9: 19. Incorporate notes about providing a clay liner in the west basin; see details in comment #45. 20. Please propose and submit a more permanent product for the pond EOF, such as rip rap. Sheet 10: 21. Provide provisions to restrict fencing around the sanitary manhole in the backyard of lot 8 block 2. 22. The proposed watermain should be looped to the 18" main near the water tower. A wet -tap connection will be acceptable. The proposed watermain should be 8" DIP within the site and will be reduced to 6" to make the connection at the northern plat boundary. Bolton & Menk is an equal opportunity employer. Hamlet Heights Preliminary Plan Review Page: 3 23. Move the proposed hydrant from between Block 2 -Lot 7 and Block 2 -Lot 8 to between Block 2 - Lot 8 and Block 2 -Lot 9. Add an additional hydrant between Block 2 -Lot 4 and Block 2 -Lot 5. 24. Maintain 10' separation from hydrant and CBMH 163. 25. The existing trunk sewer structures are lined and when adjusted they will require the same lining product (Zebron 300 series liner) to be installed. 26. Since the sanitary structures are being adjusted, provide 27" cones and castings. 27. Provide access to the existing trunk sewer during construction. Cka + 11 28. Extend the FES -201 to the Hamlet Pond normal water level of 777.5 in an effort to minimize erosion. See attached plan sheet for pond details. 29. FES -107 should be changed to a catch basin structure per STO-9 or STO-10 and not a flared end. 30. Evaluate options to straighten FES -107 to CB -104 and eliminating the bend at structures 105 & 106. 31. Try to achieve 3' minimum cover over storm pipe in street. It appears 2' min cover in greenspace is achieved. 32. On the removal plan, confirm the FES from the Pine Hill basin will be removed. 33. Provide a detail for OCS-100. 34. Move CBMH-111 and CB -112 to lot lines. Sheet 13-14: 35. Include pond benching detail City Plate STO-18. 36. Note that the sidewalk is not to be constructed on detail STR-2. 37. Add the concrete hydrant pad detail (City Plate WAT-9). 38. Include City Plate STR-10 for bituminous trail construction. 39. Please note that the existing trunk sanitary pipe has been lined with a CIPP. A new connection detail is provided at the end of this memo. Sheet L1: 40. Boulevard trees should be located 10' behind curb. 41. Maple boulevard trees should not be provided. Consult with the City forester for acceptable replacement species. 42. Trees should not be planted over utility pipes (storm sewer) or hinder access routes around the ponds or to drainage structures. Stormwater: 43. There is a regional pond immediately to the east of this site, pond TG -P4. The HWL of this pond, 786.14, needs to be accounted for as it relates to tailwater and freeboard requirements. a. Freeboard standards: For stormwater facilities with emergency overflows, the low entry elevation for all new structures must be a minimum of 3 feet above both the peak surface water elevation for the 100 -year precipitation event and 2 feet above the Bolton & Menk is an equal opportunity employer. Hamlet Heights Preliminary Plan Review Page: 4 emergency overflow elevation of any immediately adjacent new stormwater basin. The submitted grading plan for this basin must identify the direction of overflow and provide adequate flowage easements for the overflow. For backyard and side -yard conveyance and temporary ponding areas, there must be at least 1 foot between the overland overflow elevation and the low entry of the adjacent structure. b. It appears Lots 3-11 block 1 and lots 1-2 block 2 do not meet the low opening requirement. 44. The Stormwater Management Plan narrative states: "The discharge from the existing stormwater basin located on the Pine Hill Elementary School property will be contained in a pipe and routed to the site's storm water treatment facilities." Please provide additional information or a drawing of the existing and proposed Pine Hill basin outlet structures. 45. A 3 -foot minimum vertical separation is required from the bottom of both the pond and infiltration system to top of bedrock, should it be encountered. Place a 1 foot minimum liner along pond bottom up to pond NWL. Liner shall have a maximum permeability of 1X10-6 CM/S with a minimum 15% passing the #200 sieve. If encountered, bedrock should be over -excavated a minimum depth of 1' below finished grade in areas above the NWL. 46. Provide a sump for pretreatment in STMH-203, CBMH-103, CBMH-154, & C13-163. 47. NPDES Construction Stormwater Permit: As this project disturbs more than 1 acre, an NPDES Construction Stormwater Permit will be required. The preliminary plans include erosion control features. A SWPPP will also be required along with the NPDES Permit. 48. On-site storm sewer should be sized to a 5 -year rational method design. Submit design calculations for the storm sewer system. a. Please submit a drainage area map for each catchment. b. Include individual pipe segment velocities with calculations for review. c. Design pipes from basins to carry both the 100 -yr pond discharge and 5 -yr design flow for directly connected areas 49. Update modeling to reflect the attached outlet on the Pine Hill site 50. Water Quality: The City requires that new development projects include BMPs that at a minimum achieve post -development reductions in TP and TSS by 50% and 80%, respectively. Since the project site drains to the Mississippi River, Watershed rules call for TP loading rate of 0.22 lbs./acre/year or existing loading rates, whichever is less. c. MIDS Summary: The applicant submitted a MIDS summary for the proposed condition of 16.37 acres draining to Pond 100 (this area does not include the Pine Hill Elementary School area which is treated on the school site). Due to the use of both a stormwater pond and an infiltration basin, it seems likely that water quality requirements will be satisfied, but the applicant will need to submit a MIDS analysis of the existing conditions within the P100 drainage area to demonstrate compliance with the watershed TP loading rule. In addition the applicant needs to include in the analysis the existing and proposed conditions within the 3.03 acres of drainage areas 2005 and 200. These areas include backyards and a drainage swale discharging offsite. Bolton & Mark is an equal opportunity employer.
