The total parcel is 6.76 acres,with 0.48 acres of wetland, 0.83 acres of new and 0.41 acres of"implied 33'Oakgreen Ave.ROW". This results in a gross density of 1.92 units per acre and a net density of 2.58 units per acre. The average lot area is 18,485 Ft2 and the minimum lot area is 12,327 Ft2. The site is located South of Oak Park Blvd. and East of Oakgreen Avenue North in Oak Park Heights, Minnesota. The surrounding land uses to the east, south and west are single family residential homes of comparable size to proposed development. The properties to the north and Northwest are developed with medium to high density residential. Access to the site is accomplished through a connection to Oak Park Boulevard,the street/driveway serving City Hall. The project is proposed to be developed as a PUD to address minor reductions in lot,street right of way widths, and building setbacks, wetland buffer width averaging, and tree mitigation. These alterations to the ordinances along with a minimized street width of 28 feet are requested in part to reduce impervious area within the site, avoid direct wetland impacts, and work around the existing home in the SW corner of the site. The reduced right of way has the added benefit of moving the homes closer to the street resulting in less tree loss. EXISTING SITE CONDITIONS The site is presently occupied by a single family home with a variety of outbuildings. There is an "exception" to the plat in the southwest corner that is occupied by an existing single family home creating an irregular boundary. The site has significant existing tree cover, some of which is in a natural state, but the majority of which is a maintained landscape. See sheets L1.1 and L1.2 for an inventory of the significant trees on the property There are four wetlands on the site as delineated by Kjolhaug Environmental Services Company,Inc. and approved by a Technical Evaluation Panel in the fall of 2013. All four wetlands were determined to meet the criteria for Managed 2 classification resulting in the requirement for a 30 feet buffer. A copy of the wetland delineation is attached. A geotechnical report has been commissioned and the field work completed. The report is expected within the coming week. The Web Soil Survey indicates the prevalence of Santiago Silt Loam and Kingsley Sandy Loam, hydrologic soil group (HSG) B and Freer Silt Loam HSG C. A copy of the soil map is attached. .4 Page2of6 DESIGN LAS Page 2 of 9 Palmer Station Neighborhood Oak Park Heights,MN June 2,2014 A portion of the site flows to the north to a wetland in the northeast corner of the site and to a depression that runs parallel to Oak Park Blvd. These two basins are drained by the same storm sewer system. The balance of the site flows to the south through a series of small wetlands and depressions and leaves the site via a swale between two homes. There is approximately 16 feet of overall relief on the property. COMPREHENSIVE PLAN AND ZONING The project site is guided for Low Density Residential in the City's 2008 Comprehensive Plan. Low Density is defined as 1-3 units per acre. The proposed project is in conformance with the plan. The City's Zoning Map designates the site as Open Space Conservation,a holding district. It is requested that the site be re-zoned to Residential Planned Unit Development for the reasons outlined elsewhere in this narrative. STREET ACCESS It is proposed to access the property from Oak Park Blvd. During the site design process the alternative to provide a connection to Oakgreen Avenue,but this was deemed unacceptable due to sight distance and proximity to the Oakgreen/Oak Park intersection to the north and Oakgreen/56th street to the south. As a result the Oak Park Blvd connection was selected resulting in a cul-de-sac street of approximately 600 feet in length. To access Oak Park Blvd. the cul-de-sac to be named Oak Cove,must cross a narrow strip of City owned property. An easement for this purpose must be obtained from the City. TRAIL ACCESS The City's trail system includes separated off street trails on the west side of Oakgreen Avenue and the South side of Oak Park Blvd. It is our understanding that at some point the trail on Oakgreen I will be extended north to Oak Park. There are no trail connections to the fully developed properties to the south or east. Given the size of this neighborhood (13 lots) and the proximity to the Oak Park Blvd. trail(average 300 feet) additional trails are unwarranted. It has been suggested that a trail connection be provided near the southern end of the neighborhood to the Oakgreen trail. It is our opinion that this is unnecessary for the reasons stated above and unwise given the inherent danger of crossing a relatively busy street mid-block. MUNICIPAL UTILITY AVAILABILITY A 12"watermain is available to serve this property in Oak Park Blvd. It will require open cutting the street and wet tapping the line. No interruption to other users is expected. A new 8 inch watermain will be extended to serve the new homes. A new sanitary sewer will be constructed in the intersection of Oak Park Blvd and Oakgreen Avenue as part of the Highway 36 reconstruction project. Connection to this system will require coordination with the state's contractor relative to timing and the physical connection.An 8 inch sanitary sewer will be extended to serve the new homes. Each individual lot will be served with a 4" sanitary sewer and 1"water service ,,,,,,,,.. mr- i Page3of6 D E S I G N L A S Page 3 of 9 Palmer Station Neighborhood Oak Park Heights,MN June 2,2014 PROPOSED ON-SITE STORM WATER MANAGEMENT The development has been designed to maintain or reduce the rate and volume of runoff from storm events up to and including the 100 year 24 hour event. The runoff from the front half of the homes, and front yards is directed to the street where it flows north in the gutter to approximately station 1+15 where it is directed by concrete flumes to pretreatment forebays, designed to remove the majority of the suspended solids. These forebays are interconnected with a 12"RCP culvert. Once the forebays reach a depth of approximately 2 feet they overflow to an infiltration basin. For events producing runoff in excess of the capacity of the infiltration basin the water will back up the flumes and enter the storm sewer system to be directed to the detention basin,which discharges into wetland #4 and then to the storm sewer in Oak Park Blvd. Runoff from the back yards and the back 1/2 of the homes in the northwest corner of the site drain to the existing depression adjacent to Oak Park Blvd. This basin discharges to a new 8"PEP outlet adjacent to the proposed cul-de-sac, as well as an existing 12" RCP flared end section (FES) in the Southeast corner of Oakgreen Avenue North and Oak Park Blvd. Both of these outlets connect to the storm sewer in Oak Park Blvd. Given the unconnected nature of the impervious areas designated infiltration areas are not proposed in this basin. Runoff from the backyards and back 1/2 of the homes in the southwest corner of the site drain to wetland #1. This wetland overflows to the basin in the southeast corner of the site. Given the unconnected nature of the impervious areas designated infiltration areas are not proposed in this basin. Stormwater is pretreated before it enters the wetland by existing grassed waterways including small depressions that promote infiltration and suspended solid removal. Runoff from the backyards and back 1/2 of the homes in the southeast corner of the site drain to a swale that includes wetlands #2 and#3 and end in an infiltration basin at the south end of the site. There is no discharge from the site in the proposed condition for the 2 year event and runoff volumes and rates are reduced for the 10 and 100 year events. Stormwater is pretreated before it enters the wetlands by the wetland buffers that promote infiltration and suspended solid removal. The infiltration basins have effectively managed to the predevelopment rates and volumes as demonstrated in the HydroCAD model which has previously been provided to city engineering staff. TREE PRESERVATION The trees on the site were identified and located by Cornerstone Land Surveying. There are a total of 126 significant trees on the site,four of which are dead. Per code,site development will necessitate the removal of 36 trees requiring mitigation based on the following calculations: Total healthy significant trees: 122 trees,3,227 inches Total significant trees removed: 36 trees, 1,076 inches Mitigation formula: (inches lost/total inches) * 1.33 *inches lost= required replacement with a 10%credit if more than 50% of trees are preserved It is also required to mitigate removed native woody vegetation at the rate of one tree per 1000 Ft2 6-- y Page4of6 D E S I G N A O Page 4 of 9 Palmer Station Neighborhood Oak Park Heights,MN June 2,2014 These formulas result in the requirement for the installation of 195 trees, as detailed on sheet L1.2. As part of the PUD it is proposed that the mitigation be accomplished in two ways; perimeter plantings at the time of initial site construction and a minimum of five "yard" trees by the builder after home construction. The plans indicate how many of the yard trees must be installed in the boulevard to meet the city's code. We believe that this approach will accomplish three important goals; the perimeter trees provide screening of the project from the existing neighbors and of the surrounding streets for the new residents,avoiding damage to the boulevard trees by the builder,and installing trees more uniformly throughout the project. WETLANDS There is no direct wetland impact as a result of this proposed project. The four wetlands are all classified as Managed 2 resulting in 30 foot buffers. The required buffers are shown on the grading plan. It is proposed to place limited stormwater treatment facilities within the buffers. It is also proposed to build a retaining wall within the wetland#1 buffer. As part of the PUD it is proposed to reduce the buffers of the very small seasonally flooded wetlands #2 and#3 adjacent to the proposed homes from 30 to a minimum of 15 feet. It is also proposed to eliminate the buffer above the retaining wall since the runoff flows away from the wetland. When considering this proposal one should consider the size of the typical buffers in comparison with the wetlands they are intended to protect. The City should also recognize that given the seasonal nature of these wetlands there will be a tendency of residents to disrespect the buffer. For this reason we are proposing to install metal signs at each angle point of the buffer easement and midpoint signs whenever the signs at the angle points exceeds a 60 foot spacing. These sign locations and details are indicated the C3.3 and C3.4 plan sheets. We are also proposing to mitigate the reduced buffer at a ratio of approximately 3 to 1 with the dedication of additional buffer/conservation easement over the area between and east of the wetlands. In addition to protecting the wetlands the native vegetation will provide enhanced wildlife habitat. LOT WIDTH AND BUILDING SETBACKS The zoning ordinance requires the lots to be 80 feet wide,at front yard setback,with 10 foot building setbacks from side lot lines. As part of the PUD it is proposed to reduce the lot width to a minimum of 72 feet. Our rational is that there is roughly 100 feet of frontage at the setback line per lot but because of wetlands, which are not be being disturbed, and the odd parcel shape created by the exception, not all of the frontage is buildable. The lots meet minimum depth requirements and average 18,485 Ft2. It is proposed to reduce the setbacks to account for the reduced lot widths as follows. The setback on the garage side of the home may be reduced to a minimum of 5 feet. The setback to the dwelling portion of the home shall remain at 10 feet. If the garages on adjacent homes are next to the same lot line the buildings must be separated by a minimum of 15 feet. Due to the width of the city owned property adjacent to Oak Park Blvd. it is proposed to treat lot 1 as an interior rather than a corner lot. y Page5of6 D E S I G N L A B Page 5 of 9 Palmer Station Neighborhood Oak Park Heights,MN June 2,2014 RIGHT OF WAY AND STREET WIDTHS As part of the PUD it is proposed to provide a right of width of 50 feet with an actual pavement width of 28 feet from face to face of curb (30 feet back to back),resulting in a 10 foot boulevard. In the cul-de-sac the pavement has a 45 foot radius and the right of 10 feet wider or 55 feet. HOME DESIGN Specific homes have not been designed for this project. However it is anticipated that they will be similar in style and square footage to those currently being built by Creative Homes, Inc. in the Liberty West neighborhood in Stillwater. The sales brochure for that neighborhood is attached. 6.---4/ Eli Page6of6 DESIGN A $ Page 6 of 9 5625 Oakgreen Avenue Oak Park Heights, Minnesota Wetland Delineation Report Prepared for Bill Coffman by Kjolhaug Environmental Services Company, Inc. (KES Project No. 2013-104) November 4, 2013 WETLAND DELINEATION SUMMARY • The 5625 Oakgreen Avenue site was inspected on October 14, 2013 for the presence and extent of wetland. • The NWI-map showed one PUBG/PEMC wetland complex within site boundaries. • The soil survey showed Auburndale as the hydric soil present within site boundaries. • The DNR Protected Waters did not show any DNR Protected Waters, Waterways, or Wetlands within site boundaries. • Two Type 1 (PEMA) fresh meadow wetlands, one Type 1 (PFO1A) seasonally flooded basin, and one Type 5 (PUBG/PEMB/PEMB) open water, shallow marsh and fresh meadow wetland complex were delineated within site limits. 1 5625 Oakgreen Avenue Oak Park Heights, Minnesota Wetland Delineation Report I. INTRODUCTION The 5625 Oakgreen Avenue site was examined on October 14,2013 for the presence and extent of wetland. The 6.76-acre site was located in Section 4, Township 29N,Range 20W, City of Oak Park Heights, Washington County, Minnesota. Generally the site was located southeast of the intersection of Oak Park Boulevard North and Oakgreen Avenue North(Figure 1). A single family home and shed surrounded by mowed lawn were located in the center of the site (Figure 2). Mature trees were scattered throughout the site, and a small area of woodland was located in the south one-fourth of the site. Woodland was comprised of the following species: silver maple,hackberry, green ash, black walnut, slippery elm,boxelder, common buckthorn, elderberry,honeysuckle, gooseberry, riverbank grape, Virginia creeper,violet, creeping Charlie, black nightshade, motherwort, common burdock, and white snakeroot. Topography on the site was generally highest in the center of the site and from there sloped downhill to the east and south. Surrounding land use consisted of single-family homes to the west, east, and south and multi- family housing to the north. II. METHODS Wetlands were identified using Routine Determination methodology described in the Corps of Engineers Wetlands Delineation Manual(Waterways Experiment Station, 1987)and Regional Supplement to the Corps of Engineers Wetland Delineation Manual:Northcentral and Northeast Region(Version 2.0) as required by Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act. Wetland boundaries were identified as the upper-most extent of wetlands, which met criteria for hydric soils, hydrophytic vegetation, and wetland hydrology. Wetland boundaries were demarcated with pink pin flags. Flags will be surveyed after concurrence if received from the Local Governmental Unit(LGU)of their locations. Soils,vegetation, and hydrology were documented at representative locations along the wetland- upland boundary. Plant species dominance was estimated based on the percent aerial or basal coverage visually estimated within a 30-foot radius for trees and vines, 15-foot radius for the shrub layer, and a 5-foot radius for the herbaceous layer within the community type being sampled. 2 Soils were characterized to a minimum depth of 18-20 inches(unless otherwise noted)utilizing Munsell Soil Color Charts and standard soil texturing methodology. Hydric soil indicators used in reporting are from the NTCHS Field Indicators of Hydric Soils in the United States(USDA Natural Resources Conservation Service Version 7,2010)which are commonly found in the Midwest. Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant species was taken from the 2012 National Wetland Plant List (Lichvar, R.W. and Kartesz, J.T. 2009.North American Digital Flora:National Wetland Plant List,version 2.4.0 (https://wetlandjlants.usace.army.mil). U.S.Army Corps of Engineers, Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory,Hanover,NH,and BONAP, Chapel Hill,NC.) III. RESULTS Review of Soils,NWI,and DNR Information The National Wetland Inventory Map(NWI) (Stillwater Quadrangle, U.S.Fish& Wildlife Service 1991)showed one PUBG/PEMC wetland complex within site boundaries(Figure 3). The Soil Survey of Washington County,Minnesota (http://soils.usda.gov/survey/geography/ssurgo/)showed the following soil types within or near site boundaries(Figure 4).

Four(4)wetlands were identified on the subject site(Figure 2). Corresponding data forms are included in Appendix A. The following descriptions of wetlands and adjacent upland reflects conditions observed at the time of the field visit. At that time, some herbaceous vegetation had begun to senesce and wetland hydrology was assumed to be normal for the time of season. Climatic conditions were normal based on available precipitation data(Appendix B). A survey of the wetland boundaries will be provided after field review by the LGU is complete. Wetland 1 was a Type 1 (PFO1A)deciduous forested, seasonally flooded basin dominated by a canopy of silver maple and an understory of green ash saplings. Wetland soils were very dark grayish brown silt loam with redox concentrations to 12 inches, underlain by very dark grey silt loam with redox concentrations and depletions to 24 inches, meeting the F6 indicator for hydric soil (redox dark surface). No free water or saturated soil was observed within 24 inches of the soil surface in the sample borehole. Secondary indicators of wetland hydrology included geomorphic position and the FAC-Neutral Test. Adjacent upland was dominated by a canopy of silver maple and an understory of gooseberry, common buckthorn, green ash saplings,wood sorrel and motherwort. Upland soils were very dark grayish brown silt loam to 12 inches, underlain by very dark gray silt loam to 24 inches. Upland soils lacked redoximorphic features and did not meet any indicator for hydric soil. No primary or secondary indicators of wetland hydrology were observed The delineated boundary followed an abrupt change in vegetation composition and a slight rise in topography. Wetland 1 did not correspond to any NWI-mapped wetlands, or areas mapped with hydric soil by the soil survey. The wetland is a shallow, isolated depression surrounded by moderately sloping upland. Wetland 2 was a Type 1 (PEMA) fresh meadow wetland dominated by smartweed and reed canary grass. Wetland soils were very dark grayish brown silt loam with redox concentrations to 12 inches,underlain by very dark grayish brown silt loam to 16 inches,with brown silt loam to 24 inches meeting the F6 indicator for hydric soil (redox dark surface). No free water or saturated soil was observed within 24 inches of the soil surface in the sample borehole. Secondary indicators of wetland hydrology included geomorphic position and the FAC-Neutral Test. Adjacent upland at the sample location was dominated by violet and creeping Charlie with lesser amounts of common burdock,black nightshade,prickly lettuce,wood sorrel, curly dock, Canada thistle, mare's tail, and yellow foxtail. One boxelder tree was present. Upland soils were very dark brown and very dark grayish brown silt loam to 10 inches,underlain by very dark grayish brown silt loam to 20 inches,with brown silt loam to 24 inches. Soils lacked redoximorphic features and did not meet and did not meet any indicator for hydric soil. No primary or secondary indicators of wetland hydrology were observed. The delineated boundary followed an abrupt change in vegetation composition and a slight change in topography. Wetland 2 did not correspond to any NWI-mapped wetlands, or areas 4 mapped with hydric soil by the soil survey. The wetland is a shallow, isolated depression surrounded by gently to moderately sloping upland. Wetland 3 was a Type 1 (PEMA) fresh meadow wetland dominated by reed canary grass with lesser amounts of giant goldenrod and prickly lettuce. Wetland soils were dark grayish brown silt loam with redox concentrations to 24 inches meeting the F3 indicator for hydric soil (depleted matrix). Soils were saturated at 16 inches below the soil surface in the sample borehole. Secondary indicators of wetland hydrology included geomorphic position and the FAC-Neutral Test. Adjacent upland at the sample location was dominated by Kentucky bluegrass with lesser amounts of reed canary grass, creeping Charlie, dandelion,violet, common plantain and yellow rocket mustard. Upland soils were very dark brown and brown silt loam to 8 inches, underlain by brown, dark grayish brown, and very dark grayish brown silt loam to 24 inches. Soils lacked redoximorphic features and did not meet and did not meet any indicator for hydric soil. No primary or secondary indicators of wetland hydrology were observed. The delineated boundary followed an abrupt change in vegetation composition and topography. Wetland 3 did not correspond to any NWI-mapped wetlands, or areas mapped with hydric soil by the soil survey. The wetland is a defined, isolated depression surrounded by moderately sloping upland. Wetland 4 was a Type 5 (PUBG/PEMC/PEMB) open water, shallow marsh and fresh meadow wetland complex. Shallow marsh was dominated by cattail. Fresh meadow was dominated by reed canary grass with lesser amounts of stinging nettle and sedge. Wetland soils were black mucky loam to 4 inches, underlain by dark grayish brown silt loam with redox concentrations to 24 inches, meeting the F 1 (loamy mucky mineral), and F3 (depleted matrix) indicators for hydric soil. Soils were saturated at 16 inches below the soil surface in the sample borehole. Secondary indicators of wetland hydrology included geomorphic position and the FAC-Neutral Test. Adjacent upland at the sample location was dominated by reed canary grass and quackgrass with lesser amounts of common burdock, Canada thistle, black nightshade,prickly lettuce, creeping Charlie, and yellow rocket mustard. Upland soils were very dark brown and dark brown sandy loam to 10 inches, underlain by very dark gray silt loam with redox concentrations to 24 inches. The upper soil horizon was uncharacteristic in texture and is likely former fill. Sub-soils were considered to be hydric based on the dark matric colors and the presence of redoximorphic features that would be closer to the soil surface had not the fill been place. No primary or secondary indicators of wetland hydrology were observed. The delineated boundary followed an abrupt change in vegetation composition and topography. Wetland 4 corresponded to an NWI-mapped PUBG/PEMC wetland, and an area mapped with hydric soil (Auburndale)by the soil survey. The wetland is a defined, isolated depression surrounded by moderately sloping upland. 5 Other Areas No other areas with wetland vegetation or hydrology were observed on the site. No other areas were shown as wetland on the NWI map, and no other areas mapped with hydric soil were shown on the soil survey map. 6 V.
