Background
History
In August of 2018, a land use amendment, a zoning amendment, and a preliminary and final plat
were approved for a proposed duplex development on the Bloomquist properties (9930 Military
Road and 6630 Keats Avenue) for 44 units, which was called Stoneybrooke Villas. At the time,
the 2030 Comprehensive Plan designated these parcels for high and medium residential land
use. The market conditions at the time had not supported high density residential development,
therefore, the Developer requested a land use amendment to guide both parcels for medium den-
sity. The proposed amendment worked well with the surrounding low-density residential uses in
the area and continues to be guided in the 2040 Comprehensive Plan as medium density
residential.
The property was not sold at that time given the Developer was unable to finance the project. The
Stoneybrooke project was not completed with the approvals in 2018. Donnay Homes purchased
the properties in 2020 and the previous resolutions for the Stoneybrooke project were rescinded
in 2020.
Site Conditions
The 18.95-acre site is made up of two separate parcels, as indicated below:

The 18.95 gross acres at 9930 Military Road and 6630 Keats Avenue are made up of two prop-
erties, both of which are currently farmland with two residential dwellings in total, as well as several
farm structures in the southeast and northeast corners. The site abuts the under-construction
Woodward Ponds development to the west, the Eastridge Woods development to the south, and
the Knutson tree farm to the north.
Planning Considerations
Plan Review
The dates of the plan set utilized for this review were submitted by Pioneer Engineering and are
dated September 24, 2020.
Conformance to the East Ravine Master Plan
The proposed Glacial Valley Estates preliminary plat is located within Neighborhood One North
of the East Ravine Master Plan. The Plan indicates this area, in the north portion of Neighborhood
One near Cedarhurst Mansion, to be focused for medium and high density residential and to align
with the proposed commercial node at 70th Street and Keats Avenue.
Land Use and Zoning
The property is guided for Medium Density Residential in the recently approved 2040 Compre-
hensive Plan. No changes in land use are proposed with this development.
The property is currently zoned R-5, Medium Density. The requested rezoning from R-5, Medium
Density Residential, to R-5, Medium Density Residential with a PUD, would be in accordance with
the long-term growth plan for these parcels. Medium Density Residential allows for 5 to 13 units
per acre density; the proposal indicates 10.29 net acres/unit.

Page 4 of 23
The proposed preliminary plat and the land use map from the City’s Future Vision 2040 Comprehen-
sive Plan are consistent in the following ways:
The Future Land Use Map in the Future Vision 2040 Comprehensive Plan identifies the future
land use development of the applicant’s property for medium density residential land uses. The
Developer is proposing attached four-plex buildings and lots for the property, which is consistent
with the City’s Future Vision 2040 Comprehensive Plan.
Trail and sidewalk connections are proposed and acceptable to the City.
The proposed private streets are consistent with City standards, if approved by the City Council.
The proposed preliminary plat and grading plan are consistent with the medium density residen-
tial land use designation for this area.
Preliminary Plat
The preliminary plat, as proposed, depicts a logical development of a viable property given the
adopted performance standards of the zoning district. The proposed plat consists of 100 units,
which equates to a density of 10.29 net units per acre, aligning with the Comprehensive Plan
guidance of 5 to 13 units per acre.
Preliminary Site Plan
Neighborhood Meeting
The Developer (Donnay Homes) held a neighborhood meeting on October 6, 2020. Notice of the
neighborhood meeting was sent to surrounding property owners within 500 feet of the project
area. The intent of the meeting was to give neighboring property owners the opportunity to ask
questions and present concerns they might have to the Developer in the early planning stages of
the proposed project. No residents attended the meeting nor have comments been received.

Zoning Development Standards
The development performance standards of the requested zoning district classifications are
detailed below.
Lot Development Performance Standards
Proposed Glacial Valley Estates
Zoning R-5/PUD
Standard R-5
Minimum lot width 60 feet 45 feet
Minimum side yard setback House 7.5 feet 7.5 feet
Minimum front yard setback 30 feet 25 feet
Corner lot setback 20 feet 20 feet
Maximum Principal structure height 35 feet 35 feet
Maximum lot coverage - Impervious Surfaces 40 percent 48 percent
The proposed 25-foot front yard setback would allow for a layout of the quad unit buildings that
provide for the required additional buffer area between Keats Avenue as well as along the Military
Trail Corridor. This proposed layout also allows for additional open and green space within the
development and reduces the amount of impervious surface within the development as a whole.
The proposed minimum performance standards align with the approved Woodward Ponds devel-
opment to the west. City ordinance requires a 75-foot landscaped buffer to be provided along
Keats Avenue, which the Developer has proposed on their submitted plans. As a part of the PUD
staff has permitted the proposed patios of the buildings facing Keats Avenue to extend within that
buffer, understanding the proposed landscape will continue to provide the intended buffer along
the major roadway. The Developer’s proposed impervious surface on the site is slightly greater
than the permitted 40 percent, although, given the provided additional buffer area along Keats
Avenue and along the Military Trail Corridor, the development will have sufficient green and open
space.
Homeowners Association
A homeowners association (HOA) will be created for the Glacial Valley Estates development. This
HOA will be responsible for all yard maintenance on each lot and outlot and snow removal on
sidewalks, driveways, and the private driveways. The water, sanitary sewer, and public storm
sewer utilities beneath the roadways and within drainage and utility easements will be the City’s
responsibility for maintenance and/or repair. All private storm infrastructure will be the responsi-
bility of the HOA for repair and maintenance. The HOA will be responsible for maintenance and
repair of all private drives within the development. The declaration of covenants for this HOA will
also include private regulations regarding parking, exterior storage, landscaping improvements,
etc. All phases of the project must be in the same HOA.
Transportation
Access to the development is proposed off Keats Avenue as well as through the Woodward Ponds
development to the west. The proposed Keats Avenue access is a County approved access as it
meets their access management plan. The Developer will be required to secure all Washington
County required permits for work within the County ROW including the installation of a right turn
lane on Keats into the proposed development. This access will extend through the development
and connect through to the Woodward Ponds development to the west. The additional access
Planning Staff Report – Glacial Valley Estates
Case Nos. ZA2020-047 & PP2020-048
October 26, 2020
Page 6 of 23
onto Keats Avenue will help shift traffic currently utilizing the Eastridge Woods development to go
north/south to now utilize the extended Jody Avenue to connect to Keats Avenue to travel north
or south.
The Developer has proposed a public street extending north from Jody Avenue to the property
line between the Knutson Tree Farm and the development (Jorgensen Avenue). This road
segment is proposed to be consistent with the City’s street standards and will be constructed as
a 28-foot face-to-face with a required 60-foot right-of-way to be platted. A temporary cul-de-sac is
required for turn around purposes per public safety at the north property line for fire and emer-
gency uses to allow for emergency vehicle turnround, given there is only one outlet for this street.
Access to each residential lot is proposed to be from private streets a minimum of 22 feet wide
(from face-of-curb to face-of-curb). These private streets will be owned, maintained, and repaired
by the proposed homeowner’s association for this project. No parking on either side of the private
streets shall be permitted and theses streets will be required to be signed appropriately.
Street Names
All assessment waiver conditions from the Ravine Parkway assessment have been paid.
Parking
The City’s Zoning Code requires no less than two parking spaces provided per unit within a multi-
family development. The proposed plan provides two spaces per unit within the driveway access-
ing each unit. Driveways are proposed at 23.5 feet in length from the building front to the back of
curb allowing for the parking of a standard vehicle without impacting the private drive.
Additional parking is also required for multi-family developments at 1.5 spaces per 10 dwelling
units. This equates to 15 parking spaces required as guest parking for the proposed 100 dwelling
units. The Developer has proposed 27 spaces, thus meeting the City’s Zoning Code standard. No
Planning Staff Report – Glacial Valley Estates
Case Nos. ZA2020-047 & PP2020-048
October 26, 2020
Page 7 of 23
parking on either side of the private streets shall be permitted, and the Developer shall be respon-
sible for posting no parking signs on those private streets.
Trails and Sidewalks
The Developer has proposed a sidewalk along one side of Jody Avenue as well as Jorgensen
Avenue through the development. The Developer is proposing a sidewalk connection from the
Jody Avenue sidewalk in the southwest corner of the site to the Military Trail Corridor. This side-
walk connection would extend from the west side of the first private drive in the southwest corner.
The provided 16-foot right-of-way along Jorgensen Avenue within the development also allows
for a sidewalk on the east side providing pedestrian connections throughout the development and
future development to the north. The Developer will construct the trail connection within the Keats
Avenue right-of-way. This trail will extend from the Military Trail Corridor to the north end of the
proposed development site.
The remaining Military Trail construction between Ravine Parkway and Keats Avenue was com-
pleted as a part of the Woodward Ponds development currently under construction. The Devel-
oper provided this construction as a part of Woodward Ponds; therefore, no additional trail
construction to make that connection is required as a part of Glacial Valley Estates.
Proposed Sidewalk and Trail Connections
Stormwater Management Plan
Storm sewer will be extended from streets within the development to the stormwater basin along
the west side of the development. The proposed basin would be combined with the proposed
basin within the Woodward Ponds development. The outlot was not platted as a part of the
Woodward Ponds First Addition, and therefore, would be required to be platted along with the
additional outlot from the Glacial Valley development. The proposed basin requires 20-foot wide
access points for future maintenance of the pond and infrastructure.

Stormwater Infrastructure
All storm infrastructure within private streets or common lots within the development will be re-
quired to be maintained by the HOA. As part of the Engineer review, the applicant must submit
updated plans indicating clearly the private stormwater infrastructure proposed for the site. The
preliminary stormwater management plan and wetland delineation was submitted and reviewed
by the City’s engineering staff, and their comments are included in a plan review letter dated
October 19, 2020. The Developer’s engineering consultant will continue to work with the City
Engineer and SWWD to address stormwater storage basins and drainage.
Grading
As with all new development projects, site grading is necessary to provide on-site stormwater
detention, street and building pad elevations, and drainage swales for routing surface water runoff
to appropriate storm sewer systems. Each building pad will be graded above the street elevation
and at least three feet above the ordinary high-water elevation for stormwater basins. As noted
on the preliminary grading, drainage, and erosion control plan, silt fence will be installed along the
perimeter of the grading limits. Part of the grading requirements for the site includes construction
of the required ponding for the site. This pond will be owned and maintained by the City.
The preliminary grading plan was reviewed by the City’s engineering staff, and their review com-
ments are included in the October 19, 2020, memorandum. Additional grading review will be
required upon submittal of final grading and utility plans for the site.

Utilities
These properties are located within the Metropolitan Urban Service Area (MUSA) and have public
water and sanitary sewer available at Jody Avenue at the west property line adjacent to Wood-
ward Ponds as well as water available in the southeast corner at Keats Avenue. The utilities at
the west property line were stubbed for continued development at the time Woodward Ponds
utilities were installed.
Utility (Sanitary Sewer & Water) Connection Points
Utilities will be required to be stubbed at the Knutson property line at the north edge of the devel-
opment. No easement would be necessary from the adjoining property owner as the temporary
cul-de-sac to be installed will need to be removed at such time future development of the proper-
ties to the north takes place; therefore, the water connection can be maintained on the south side
of the property line. A temporary cul-de-sac will be required at the end of Jorgensen Avenue until
such time the street continues through the Knutson property as a part of future development. The
cost of removal of the temporary cul-de-sac for future road extension on the Knutson parcel to the
north will be the responsibility of the Developer and this cost will be required in advance of the
future extension as a part of the Glacial Valley Estates Development Agreement.
The installation of the on-site utilities, roads, and supporting infrastructure will be privately de-
signed and constructed to meet City specifications. The Engineering memo dated October 19,
2020, addresses the connections for the project. Drainage and utility easements are required over
all HOA outlots, including private street outlots allowing access to public infrastructure.

Tree Preservation and Landscaping
City Code Title 11-6-19 requires completion of a tree inventory (all qualifying trees) for the entire
project area. The completed inventory indicating all qualifying trees on the site and whether they
are to be removed or saved as a part of the proposed project has been provided. The inventory
requires replacement of 316 caliper inches, which are being removed in excess of the permitted
50 percent removal threshold for a project of greater than 10 units per acre net density. This
requires installation of deciduous trees at a replacement rate of one tree equals 2.5 replacement
inches or a coniferous tree at a replacement rate of 2 inches per foot (six foot minimum).
City Code Title 11-6-5 requires a minimum amount of landscape plantings to be installed as a part
of development projects within the City. These required plantings include boulevard trees, building
perimeter plantings, and landscape requirements. The submitted landscape plan preserves a
large portion of mature trees along the south side of the development along the Military Trail
Corridor. Additional plantings are proposed throughout the subdivision including the required land-
scape buffer along Keats Avenue on the east side of the development.

required mitigation inches. The Developer will be required to pay in lieu of planting the required
trees at a rate of $150.00 per mitigation inch that is not mitigated on site. The table below indicates
the required plantings for the proposed project:
Required Plantings Calculation
The City Forester is reviewing the proposed landscape plan to ensure tree locations do not inter-
fere with utility infrastructure, pond access routes, hydrants, traffic signage, and street lighting,
and that it aligns with the City’s preferred tree species list. The Developer is required to comply
with the City Forester’s recommendations for any tree species and location.
Shrubs will be required to be planted as landscape surrounding each building at a rate of five
plants per dwelling. Irrigation will also be required in all landscaped areas throughout the project
area to the back of curb. All plantings and trees within the outlots and throughout the site, as well
as the vegetated areas up to the back of curb of Keats Avenue and the Historic Military Trail
Corridor, will be required to be maintained (mowed) by the homeowner’s association.
Park Land and Open Space
A minimum of 10 percent of developable area shall be required to provide residents with public
recreation facilities including parks and open spaces as a part of development projects per City
Code Title 10-4-3. The City’s Comprehensive Plan does not guide a portion of this project area
for future park and open space; therefore, no park dedication land is required. The Developer
would be required to pay a park dedication fee in lieu of dedicated lands for open space.

The Comprehensive Plan guides for a large city park on the north side of Ravine Parkway pro-
posed to be called Glacial Valley Park. The proposed park will include ball fields, ice rink, basket-
ball courts, and a soccer/football field. The proposed development would have access through
sidewalk connections as well as trail systems (along Keats Avenue) to this future park.
Planned Park (north of Glacial Valley Estates)
The applicant has also verified the development aligns with City Code Title 11-9E-5B, which al-
lows for only 40 percent of the total area of the project to be covered with structures, driveways,
streets, and other impervious surfaces in order to maintain a balanced development. The project
also provides for far greater than the required 400 square feet of open space per dwelling, with
approximately 3,320 square feet of open space per dwelling.
Park and open space markers are required to denote City-owned lots. The diagram below notes
the required park and open space markers for the future City owned outlots:

Area Charges and Development Fees
Area charges and related development fees for this project will be based on the acreages shown
on the final plat. These fees and charges will be accurately adjusted based on the final plat layout
and be provided in the development agreement. All fees and charges will be memorialized within
the development agreement. Payment to the City will be required at the time the development
agreement is fully executed by the City and Developer.
Architecture
The Developer and builder, Donnay Homes, is proposing quad townhome buildings within the
Glacial Valley development. This proposed attached unit townhome product is similar to the prod-
uct currently under construction within the Mississippi Dunes townhome development south of the
Mississippi Dunes and Summers Landing single-family developments. Donnay Homes has pro-
posed additional architectural materials as well as color pallets for the proposed products given
the location within the East Ravine Neighborhood, including a stone accent. Each unit proposed
have three bedrooms, three bathrooms, are approximately 1,600 square feet in size, and priced
within the $300’s.
Product Elevation
Fencing
Any proposed fencing as a part of the development would require long-term maintenance by the
HOA.
The Developer has communicated with the neighboring property owner (Knutson Tree Farm) to
the north. Mr. Knutson has indicated his concerns related to potential trespassing onto his prop-
erty with the development so near his property line. As part of the Woodward Ponds development,
the Developer and Mr. Knutson agreed that the Developer would install wrought iron fencing along
the property lines abutting Mr. Knutson’s property. The Developer of Glacial Valley will be respon-
sible for installation of fencing along the north property line. The fence should be placed on the
Glacial Valley side of the property line and maintained by the HOA.

way grading has been completed in order to preserve the lot markers for future property
owners.
42. The Developer is responsible for the cost and installation of public land boundary markers
at the corners of private property abutting all outlots owned by the City. The boundary
markers are $115 per marker and are to be picked up at the Cottage Grove Public Works

the City Engineer.
49. The Developer shall weekly, or more often if required by the City Engineer, clear from the
public streets and property any soil, earth, or debris resulting from construction work by the
Developer or its agents or assigns. All debris, including brush, vegetation, trees, and dem-
olition materials, shall be properly disposed of off-site; burying construction debris, trees,
and other vegetation is prohibited. Burning of trees and structures is prohibited, except for
fire training only.
50. The Developer grants the City, its agents, employees, officers, and contractors’ permission
to enter the site to perform all necessary work and/or inspections during grading and the
installation of public improvements by the Developer.
51. Upon acceptance of the public improvements by the City Council, all responsibility for the
improvements must be assumed by the City, except that the Developer is subject to a one-
year warranty on the construction of the improvements from the time of acceptance by the
City of all public improvements.
52. The City will not have any responsibility with respect to any street or other public improve-
ments 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 Developer,
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 com-
pliance with the approved construction plans, profiles and specifications, as required by
the city ordinance. Upon satisfactory completion of all construction in accordance 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 re-
sults, the City Engineer will notify the Developer in writing of the City’s approval of the

55. 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 pro-
posed 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.
56. 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.
57. The Developer acknowledges in the development agreement that prior to the construction
of the improvements, site conditions, access to paved roads, and fire hydrants will be sub-
standard and will not be optimized until the improvements are completed. To the fullest
extent permitted by law, Developer agrees to indemnify the City, its officers, employees,
agents and others acting on its behalf and to hold them harmless 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 ex-
penses of defense, which result from, or otherwise 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 contractors, 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 emergency 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, indem-
nification obligations for claims arising prior to the completion of the Improvements shall
survive the termination of the agreement.
58. 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 dump-
ster to contain all construction debris, thereby preventing it from being blown off-site. It is
the responsibility of the Developer to ensure no debris blows on or off site.

59. 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.
60. 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.
61. 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 deter-
mined at the sole discretion of the City, the City may take such action as it deems appro-
priate 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.
62. 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.
63. 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.
64. The Developer shall comply with the 1991 Wetlands Conservation Act, as amended.
65. 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.
66. 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

These improvements are all in conformance with City approved plans and specifications
and will be installed at the sole expense of the Developer in conformance with Title 10,
Chapter 5 of the City Code; or if in lieu of the Developer making said improvements, the
City proceeds to install any or all of said improvements, under the provisions of Chapter
429 of the Minnesota Statutes, the City Council may reduce said Letter of Credit by the
amounts provided, upon the ordering, for those public improvements so undertaken. The
Letter of Credit must have the same expiration date as the Developer’s contract.
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 extended 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 improvements are not com-
pleted, 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 devel-
opment agreement.
67. The Developer must post a cash escrow with the City’s Finance Director to cover engineer-
ing, 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.
68. The Developer must post a cash escrow with the City’s Finance Director to cover engineer-
ing costs and other City services, expenses, and materials provided in reviewing and pro-
cessing 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 es-
crow amount will be included in the development agreement.
69. Temporary parking during construction shall be permitted on only one side of the street.
