Craig Allen 10850 Old County Road 15 Suite 200 Plymouth, Minnesota 55441 Telephone: 952-270-4473 Email: craig@gonyeacompany.com The developer is proposing a community of 91 single family homes on +/- 39.84 acres of land located on the east side of Lake Elmo Avenue (CASH17), approximately 525 feet north of 39th Street North. The developer is requesting Final Plat for 46 of the 91 single family homes in Phase 1 on +/- 25.6 acres of the total +/-39.84. This proposed residential development will consist of higher end single family homes. It is anticipated that these homes will range in price from $400,000 to $750,000. The development is located in an area of Lake Elmo with easy access to the transportation system. This will provide the future home owners a secluded place to live that is located within minutes of all the amenities Lake Elmo has to offer with the regional facilities of the larger metropolitan area. Village Preserve The project is anticipated to be constructed in two phases. The primary access is Lake Elmo Avenue. A community amenity area/park will be developed (proposed Outlot D) between the Village Preserve development and the proposed Wildflower at Lake Elmo development. Village Preserve is located within the Stillwater School District #834. Development Team: Civil Engineering, Surveying & Land Planning Sathre-Bergquist, Inc. Robert S. Molstad, P.E. David B.

Pete Schiltgen 10880 Stillwater Blvd. North Lake Elmo, MN 55042 Telephone: (651) 303-8188 Peteschiltgen@gmail.com Comprehensive Plan, Zoning, Density, & Variances: The planned Land Use is Village Urban Medium Density. On the Village Land Use Plan, the project site is classified as Village Urban Medium Density (V-MDR). The density range for V-MDR is 2.5 – 4.99 units per acre. The attached final plat shows 46 single family lots that are a minimum width of 65 feet. The smallest lot area is L4B4 – 8,455 sf and the largest lot area is L7B1 at 20,480 sf, with an average lot area of 12,469 for the entire project. Lake Elmo Zoning: LDR District Minimum Lot Area – 8,000 square feet Minimum Width – 60 feet Front Yard Setback – 25 feet Side Yard Setback – 5 feet to garage and 10 feet to living space Corner Yard Setback – 15 feet Rear Yard Setback – 20 feet Density: Total Site: Gross Site Area: 39.84 acres Gross Density = 91/39.84= 2.28 units per acre CSAH 17 ROW: 2.27 acres Open Space: 1.22 acres Net Area: 39.84-2.27-1.22 = 36.35 acres Net Density = 91/36.35 = 2.50 units per acre Variances – No variances are proposed. A final plat lot area tabulation sheet for Phase 1 is in Appendix A of this narrative. Site Analysis: The site is bordered on the north and east by the proposed Wildflower at Lake Elmo development, a Robert Engstrom Development. The site is bordered on the west by Lake Elmo Avenue and on the south by future commercial properties. The primary access to the site will be via Lake Elmo Avenue with a second access from 39th Street North via Layton Avenue North. The site is currently being used for agricultural purposes. Please refer to the ALTA Survey and the aerial photos. Utility service, sanitary sewer will be provided to the site as part of the proposed Trunk Sanitary Sewer project that will extend sewer service from the new lift station at Reid Park, north to the Site. Watermain exists on the east side of Lake Elmo Avenue and will be extended to the south east corner of the project from 39th Street North. Storm water will be managed and outlet from the site in accordance with the City and Watershed requirements. The site is within the Valley Branch Watershed District. Minor utilities (gas, electric, phone, and TV) will need to be extended to service the site. The topography of the site is relatively flat on most of the site, 940 to 945 along Lake Elmo Avenue and sloping southeast to 938 at the south east corner. The highest elevations are in the northwest corner at +/- 955. There is an existing slope in the north central portion of the site that slopes from 940 down to 920. There are no wetlands on the site. The USDA Soil Survey of the project site indicates Antigo Silt Loams, Campia Silt Loams, and Mahtomedi Loamy Sand. The soils that are present consist of mostly moderately well drained loams and sandy loams with a moderate permeability. Street Design: Village Preserve proposes to have public streets; the public streets within the project would be 28’ B-B, with a sidewalk along one side of the street, within a 60’ ROW. The cul-de-sacs will have a 45’ radius to the back of curb. All streets will be constructed to the City of Lake Elmo standard street section. Utility Services: City sanitary sewer will need to be extended to the site. Water is currently available to serve the site, see notes above. Site Grading: The site grading is planned to begin in the spring of 2015. The project will be graded in one phase. The overall graded area is +/- 38 acres. We are proposing to grade all streets to the proposed hold downs and prepare corrected building pads for all home sites. We are creating three storm water ponding areas and two infiltration areas to meet the storm water treatment requirements of the City and the Watershed. It is our design objective to balance the site with on-site material, some import of suitable structural fill material may be necessary for building pad, and street. Storm water: The storm water facilities proposed in Village Preserve are illustrated on the enclosed preliminary plans. Runoff from the site will be directed to storm sewer inlet locations, collected and conveyed to the proposed treatment pond(s) and filtration area(s). The ponds and filtration areas will provide temporary storage of storm water runoff, treatment of storm water and sediment removal. The storm water plan will provide adequate treatment and storage to meet the City of Lake Elmo and the Valley Branch Watershed District requirements. Wetlands: There are no wetlands on the site. Traffic: Village Preserve proposes one primary access point off of Lake Elmo Avenue and a secondary street connection to 39th Street North via Layton Avenue North. Traffic Generation – (anticipate 10 trips per day per home site) Total Site: 91 Lots = 910 trips per day Phase 1: 46 Lots = 460 trips per day The additional traffic generated from this site is not anticipated to have a noticeable impact on the existing traffic in the area and is on the lower end of the proposed Comprehensive Plan guiding. Trail System: Six-foot concrete sidewalks are proposed along residential streets within the site. In addition, there are 8.5 foot trails proposed to promote neighborhood connectivity as well as encourage and expand pedestrian use of Downtown. Park: The neighborhood park and a majority of the trails will be installed with Phase 1 of the development. The developer is proposing dedicating land adjacent to Reid Park in lieu of park dedication fees. The developer is working with Robert Engstrom Companies and the Lake Elmo Park Commission on possible park improvements. Woodland Areas & Protection: I. Introduction A current tree survey in accordance with City of Lake Elmo requirements has been completed for this site and is included in the submittal. The tree inventory plan is shown on the Erosion Control Plan. Only 14 trees were identified, per the City requirements. II. Tree Species, Distribution and Size: The site has 318 caliper inches of significant trees, with 15 caliper inches of exempt trees for a net total of 303 caliper inches. The trees are located throughout the site. The species include Cherry, Maple, Box Elder, Red Cedar and a few others. A table containing data on the trees, as well as a map which shows tree location, species, size and condition, are shown in the preliminary plans, please see the Erosion Control Plan. Tree Removal & Restitution: The Village Preserve development will impact approximately 61.4% of the significant trees on the site. The development is over the allowable 30% threshold and a proposed replacement plan has been prepared for the project. Landscape Plan, Monuments, & Entrance: This development will have a divided entry off of Lake Elmo Avenue and some small berming along Lake Elmo Avenue. Many of the lots will have pond views or overlook views, due to the site topography. The storm water pond and treatment areas will have landscaping to create unique water treatment facilities for the proposed project. A custom entry monument may be designed and constructed at the proposed entrance(s). This will create a sense of luxury and livability for the new single family residents, while providing safer access to the site. Homeowner’s Association and Restrictive Covenants: The developer will prepare restrictive covenants and standards that will apply to this 91 lot project. The restrictive covenants will be tailored to the developer’s vision of the project. Each home will be required to meet the specifics of building types, landscaping, and overall goals of the development. A master HOA will be created for the Village Preserve project. This association will be in charge of the monumentation, entrance, landscaping, and infiltration basins. The HOA will also be responsible for maintenance issues within the subdivision. These may include special landscaping, mailboxes, signage, and other common elements.

If erosion occurs at the outlets of the storm sewer pipes the applicant will be responsible for correcting the problem to the satisfaction of the VBWD. 14. To prevent soil compaction, the proposed infiltration area shall be staked off and marked during construction to prevent heavy equipment and traffic from traveling over it. If the infiltration facility is in place during construction activities, sediment and runoff shall be kept away from the facility, using practices such as diversion berms and vegetation around the facility’s perimeter. The infiltration facility shall not be excavated to final grade until the contributing drainage area has been constructed and fully stabilized. The final phase of excavation shall remove all accumulated sediment and be done by light, tracked equipment to avoid compaction of the basin floor. To provide a well-aerated, highly porous surface, the soils of the basin floor shall be loosened to a depth of at least 24 inches to a maximum compaction of 85% standard proctor density prior to planting. 15. All disturbed areas shall be vegetated within 14 days of final grading. 16. The applicant is responsible for removal of all temporary erosion-control measures, including silt fence, upon establishment of permanent vegetation at the project site as determined by the VBWD Engineer and/or Inspector. 17. Valley Branch Watershed District shall be granted drainage easements which cover: (a) land adjacent to stormwater management facilities, wetlands, and lowlands up to their 100-year flood elevations and (b) all ditches, storm sewers, and maintenance accesses to the stormwater management facilities.

No construction shall start until all permit conditions are met. If the Valley Branch Watershed District Board is not satisfied that the conditions are met, the permit will be revoked. 2. The infiltration material shall be in conformance with Mn/DOT Specification 3877.1G, or an equivalent specification approved by the VBWD. 3. This permit is not valid until a maintenance agreement in the general format of Appendix B of the VBWD Rules is submitted to and approved by the VBWD Attorney. 4. The permit holder must obtain permission for any work outside of his property. 5. Prior to construction, the required surety and fee shall be submitted. 6. The plan sheets shall be revised to show the correct inverts at the pond outlet structures. 7. Drain tile shall be installed around the perimeters of the foundations at Block 1, Lots 1 and 2 and the lot north of Block 3, Lot 1. 8. Plans shall be revised to show minimum floor elevations at least 2 feet higher than the adjacent water body’s 100-year flood level. 9. This permit is not transferable. 10. This permit is subject to obtaining all other permits required by governmental agencies having jurisdiction (including a NPDES permit). 11. The VBWD Engineer and Inspector shall be notified at least three days prior to commencement of work. 12. Erosion controls shall be installed prior to the commencement of grading operations and must be maintained throughout the construction period until turf is established. Additional erosion controls may be required, as directed by the VBWD Inspector or VBWD Engineer. 13. The following additional erosion controls shall be implemented on the site: a. All proposed slopes three-feet horizontal to one-foot vertical (3H:1V) should be covered with erosion-control blanket. b. Silt fence should follow existing contours as closely as feasible to limit the potential for gully erosion along the edges. c. Any sediment that collects in storm sewers, ponds, or other water management features shall be removed. d. Street sweeping shall be performed if sediment collects on streets. e. If erosion occurs at the outlets of the storm sewer pipes the applicant will be responsible for correcting the problem to the satisfaction of the VBWD. 14. To prevent soil compaction, the proposed infiltration area shall be staked off and marked during construction to prevent heavy equipment and traffic from traveling over it. If the infiltration facility is in place during construction activities, sediment and runoff shall be kept away from the facility, using practices such as diversion berms and vegetation around the facility’s perimeter. The infiltration facility shall not be excavated to final grade until the contributing drainage area has been constructed and fully stabilized. The final phase of excavation shall remove all accumulated sediment and be done by light, tracked equipment to avoid compaction of the basin floor. To provide a well-aerated, highly porous surface, the soils of the basin floor shall be loosened to a depth of at least 24 inches to a maximum compaction of 85% standard proctor density prior to planting. 15. All disturbed areas shall be vegetated within 14 days of final grading. 16.
