FINAL PLAT PROPOSAL SUMMARY The applicant is proposing a 48 lot subdivision with five outlots on 39.5 acres. Approximately 5.7 acres of the site, shown as Outlots A and D, are existing wetlands. Drainage and utility easements will be dedicated over Outlots A and D, but ownership is proposed to remain private. A public trail of 2.78 acres will be dedicated as Outlot B along the Bluff Creek corridor. Outlot C is a proposed stormwater ponding area to be dedicated to the city. Outlot E, in the northwest corner of the site, is a remnant piece that is undevelopable and is used to provide an acceptable grade to the creek. Outlot E may be used to locate an entrance monument for the site or it could be assembled with Lot 1, Block 3. Four of the proposed lots, Lots 8, 9, 10, and 11, Block 2, were not approved as part of the preliminary plat. The city will purchase this land as part of the city's park and open space system. As a condition of approval, the applicant is to show this area as an outlot on the final plat. Since the city and applicant could not agree on an acceptable price for this land, the city is proceeding with the condemnation of this property. As part of the preliminary plat, the city approved a conditional use permit for alterations within the flood plain and a wetland alteration permit. Those approvals were given based on the following conditions which still apply. Conditional Use Permit The City Council approved Conditional Use Permit #94 -4 to permit the placement of fill and excavations and alterations within the flood plain subject to the following condition: Creekside Addition Final Plat and Rezoning Second Reading May 3, 1995 Page 14 The applicant shall comply with the wetland fill /excavation and wetland mitigation conditions as stated in Corps of Engineers Section 404 permit.

All mitigation work shall be limited to the Bluff Creek corridor and not in the wetland located at the southwest corner of the site. Wetland Alteration Permit The City Council approved Wetland Alteration Permit #94 -4 to permit filling and replacing wetlands on the site subject to the following conditions: 1. All buffer areas shall be surveyed and staked by the applicant in accordance with the City's wetland ordinance. The City will install wetland buffer edge signs before construction begins and will charge the applicant $20 per sign. 2. Wetland buffer areas are required around the wetlands in accordance with the City Wetland Ordinance. The applicant shall revise the development plans to include a 50- foot buffer around Bluff Creek with a 100 foot building setback and a 10 to 30 foot buffer with a minimum average of 20 feet around the tributary to Bluff Creek with a 50 foot building setback. Staff is recommending that the City Council approve the rezoning of this property to RSF as well as final plat approval for 44 lots subject to the conditions of this staff report. The subdivision complies with all requirements of the RSF district regulations. LANDSCAPING /TREE PRESERVATION The applicant has provided a tree preservation/landscaping plan for the project that exceeds minimum code requirements. The applicant has evaluated the tree preservation plan based on the platting of Lots 8 - 11, Block 2, which the city proposes to acquire for parkland. This plan requires a minimum of 180 eighty trees be planted, but it provides a total of 189 trees. The applicant has also evaluated the tree preservation requirements based on the city taking the 2.46 acres of forested upland. In this instance, a total of 169 trees are required. The tree preservation/landscaping plan being submitted would adequately address this alternative. The Creekside Subdivision narrative: Tree Preservation and Landscaping Plan is the woodland management plan required for this development. This plan addresses the requirements of a woodland management plan. As a condition of plat approval, the developer shall provide copies of this plan to the home builders and /or home purchases. u d Creekside Addition Final Plat and Rezoning Second Reading May 3, 1995 Page 15 WETLANDS The wetlands issues have been addressed and the applicant meets the required buffer strips, setbacks, and wetland mitigation for this phase of the project. The buffer edge monumentation will be installed after the infrastructure is installed. Type III erosion control is required around the creek and the wetlands including the ponding areas adjacent to the wetlands. Future wetland impacts will be addressed with the next phase of the project. The City is encouraging the developer to restore the wetland as part of their mitigation. GRADING & DRAINAGE The final grading plans have been developed to maintain the neighborhood drainage pattern from Timberwood Estates. The lots adjacent to Timberwood Estates will be graded to match existing grades at the plat boundary. Stormwater runoff from Timberwood Estates will continue to drain through Creekside Addition as it has in the past. In addition, the storm sewer pipe has been extended along Lots 16 and 17, Block 3 to convey runoff from a low area in Timberwood Estates. The storm sewer has also been sized in accordance to the City's SWMP to provide future service to Timberwood Estates. The wooded lots in the southerly portion of the site (Lots 21, 23, 24, 25, 26, Block 3) and the parkland which is platted as Lots 8 though 11, Block 2 are proposed to be custom graded at time of building to minimize grading and tree loss. Staff recommends that a detailed grading, drainage, tree removal, and erosion control plans be submitted with the building permit application for review and approval by the City prior to issuance of the building permit for the lot. The applicant has employed the use of retaining walls along the street adjacent to the wetland on Outlot D to minimize impacts to the wetland. A guardrail has also been added for safety purposes. Retaining walls have also been used at the creek crossing in an attempt to preserve a couple of significant trees. Wetland buffer areas are shown on the grading plan adjacent to the wetlands. The buffer strips range between 0 and 20 feet and average 10 feet wide in accordance with the city ordinance. The plans propose a storm sewer system designed in accordance with the City's SWMP to convey stormwater runoff to two proposed stormwater ponds for pretreatment prior to discharging into the wetlands. The applicant has received credits against their SWMP fees for providing oversized ponds and storm sewers in accordance to SWMP methodologies. Staff has calculated the applicant's SWMP water quantity connection fee at $29,590. This fee will be payable prior to the City signing the final plat. The applicant and staff have met with the Riley- Purgatory -Bluff Creek Watershed District engineering to resolve a discrepancy with the high water level of the Bluff Creek flood plain. Creekside Addition Final Plat and Rezoning Second Reading May 3, 1995 Page 16 The grading and development plans have been designed taking into account the agreed upon flood plain level to maintain a 3 -foot grade separation between the lowest floor elevation of the dwelling and the high water level. The applicant has requested to begin site grading after final plat and construction plan approval. Staff finds this acceptable conditioned upon the applicant entering into the development contract and providing the City with a financial security to guarantee site restoration and erosion control measures. STREETS The applicant has submitted detailed street construction plans and specifications to staff for review and formal approval by the City Council. Staff finds the plans and specifications in conformance with City standards. The construction plans are also on the City Council's agenda for formal approval in conjunction with this final plat consideration. The street plans have been designed to provide access to all of the lots via a public street. No private streets are proposed. With this phase of development, there is only one access point in and out for the neighborhood. Stone Creek Drive will become a temporary deadend street in excess of 4,500 feet from the intersection of Galpin Boulevard. A temporary turnaround is being provided at the end of Stone Creek Drive with barricades indicating that this street will be extended in the future. Eventually, Stone Creek Drive will be extended northerly to tie into the City's east/west frontage road (proposed Coulter Boulevard) which will eliminate the long deadend street scenario. A condition has should be added that the applicant shall be responsible for extending Stone Creek Drive within three years after the final plat approval of Creekside Addition. The applicant is also being required to provide a financial security to guarantee construction and extension of said road. The street plans propose on a 5 -foot wide concrete sidewalk to be extended from the existing sidewalk in Hans Hagen development (Stone Creek 4th Addition). A sidewalk will be installed along the west side of Stone Creek Drive. In addition, an 8 -foot trail is proposed to meander along the Bluff Creek corridor along the east side of the development and will connect to Stone Creek Drive. UTILITIES Detailed construction plans and specifications for the utilities have been submitted for staff review and City Council approval. Staff finds the construction plans and specifications in general conformance with the City's standards. The construction plans and specifications are also on the City Council's agenda for formal approval in conjunction with the final plat approval. C ' Creekside Addition Final Plat and Rezoning Second Reading May 3, 1995 ' Page 17 The applicant will be constructing a portion of the City's trunk sanitary sewer system in ' conjunction with the development. Staff recommends that the applicant be compensated for the oversizing and extra depth cost associated with constructing the trunk sewer line versus an 8 -inch lateral line. Staff will be working with the applicant to arrive at an equitable resolution for compensation for the oversizing of the sanitary sewer line. The applicant shall be compensated by issuing credits against the properties assessment for the Upper Bluff Creek trunk improvements. Staff has also reviewed different alternatives to provide Timberwood Estates with future sanitary sewer service. Staff has prepared a separate memo with the alternatives for ' extending a sewer line through this development to Timberwood Drive (see City Council Item 2b -3). The construction plans have been designed to extend an 8 -inch sanitary sewer line along Lots 19 and 20, Block 3 to the plat boundary versus extending a line along the Bluff ' Creek tributary as previously considered with the preliminary plat review. This new alignment will not require removal of any trees or have any impact to the creek. This option gives the flexibility for two alternate routes into Timberwood Estates as well. The current construction plans have been designed with this proposal. This work will be done in conjunction with the overall development of Creekside Addition at no cost to the City. ' Staff has prepared a development contract for the applicant to enter into with the City and provide the financial security to guarantee installation of the public improvements in compliance with the conditions of approval for final plat. ' RECOMMENDATION ' Staff recommends that the City Council approve the following: ' Rezoning The final reading of rezoning #94 -4, rezoning 39.5 acres from A2, Agricultural Estate, to ' RSF, Single Family Residential, consistent with the City of Chanhassen Land Use Plan.

ATTEST: Don Ashworth, City Manager Donald J. Chmiel, Mayor (Publish in the Chanhassen Villager on , 1994.) April 27, 1995 Revised May 3, 1995 , Creekside Subdivision Narrative Tree Preservation and Landscape Plan Introduction Creekside, a 48 unit subdivision located within the City of Chanhassen adjacent to Bluff Creek, is committed to the tree preservation and protection of the natural woodlands, steep slopes and creek corridor valleys. The residential subdivision was designed to minimize the impact to the existing hardwood forest on the southern 1/4 of the site and all significant wetlands have been preserved. Heritage Development is committed to utilizing retaining walls, minimize grading and promoting advanced construction techniques so that the final residential subdivision and City may benefit from the significant hardwood forest preservation. Creekside Tree Preservation Philosophy Heritage Development finds that trees provide many benefits including: stabilization of the soil by the prevention of erosion and sedimentation, reduction of storm water runoff and the costs associated therewith, improvement of air quality, reduction of noise pollution, control of urban heat island effect, protection and increase of property values, protection of privacy, energy conservation through natural insulation, control of drainage and restoration of denuded soil subsequent to construction and grading, protection from severe weather, providing habitat for birds and other wildlife, conservation and enhancement of the city's physical and aesthetic environment, reforestation of open lands, and general protection and enhancement of the quality of life and general welfare of the city. Creekside Tree Preservation Plan Heritage Development through RLK Associates, Ltd., prepared a tree preservation plan dated April 26, 1995. This plan identifies the areas of proposed tree canopy protection, protected wetland areas, storm water pondmg areas and wetland mitigation areas. The plan also identifies the base landscape replacement plan which shall be installed by the developer. The species were specifically selected based upon compatibly to the existing tree and soil conditions and for promoting a quality hardwood tree environment throughout the subdivision. Components of the Plan EUPY Framing Stone Creek Drive at Bluff Creek is a massing of conifer trees which signal to the residents a visual land mark of entry/exit as one crosses the Bluff Creek. -1® 7 0 Prominade Stone Creek Drive has been established as the central spine of Creekside. A variety of hardwood upland tree species have been selected to provide an overstory tree canopy. The tree species are dominated by two varieties of Maple (the City's tree), three varieties of Oak, Hackberry, Honeylocust and Linden. The trees, approximately 40' on center, will frame the public right -of- way and provide a shaded and cooling micro climate for the public right -0f - -way which includes a sidewalk and connections to the Bluff Creek trail system. Individual lots north of the southern woodland are anticipated to be landscaped by the homeowners according to their specific landscape ideas. The prominade of trees on Stone Creek Drive will entice the future residents to add to the basic landscape plan. The Landscape Plan proposes an average of 2 to 3 trees to be installed on each lot along Stone Creek Drive. Upland Planting Buffer The western edge of Creekside abuts an established large lot subdivision which is heavily wooded and visually distant from Creekside for the great majority of the common property line. The landscape plan provides a layer of planting to function as a screening element and transition zone from the existing wooded edge and utility easement. A variety of species including conifers and Amur Maples interspersed with canopy trees. The area within the easement paralleling the western property line is proposed to be left in a natural/wild grass/ forbs condition. The reduced lawn area will encourage invader tree and shrub species and promote wildlife and song bird nesting areas. Woodland Lots The nine lots located at the southern corner of Creekside have existing hardwood forest consisting primarily of Sugar Maple and Bur Oak trees. The future home pads 60'x 60' and driveways have been calculated into the overall tree preservation plan. The future homes are anticipated to be designed specifically for each lot to minimize the grading and disruption to the significant trees outside the designated home pads. Storage of excavation material will not be allowed on site of lots 21, 23, 24, 25 and 26, outside of the designated 60 x 60 foot building pad area as generally outlined on the plan dated April 26, 1995 and specifically delineated on the site specific building permit application. Tree Protection Trees designated for preservation shall be protected by snow fences with clearly marked signage specifying that area is off limits for construction activities. Protective barriers must be located at the perimeter of the building pad and driveway area in order to completely protect trees being saved and must remain in place until all construction activities are terminated. No equipment, chemicals, soil deposits, or construction materials shall be placed within the protective barriers. Any understory trees and natural vegetation should be preserved within the boundaries of the protective areas. A preservation plan for lots 20, 21, 23, 24, 25, and 26 may include the use of retaining walls, requirement for post- construction deep root fertilization and soil aeration, or construction vehicle ramp systems. Preservation plans for the 6 above - mentioned lots will be established at the time of building permit application. Individual grading, drainage, erosion control plans will be required for lots 20, 21, 23, 24, 25, and 26, block 3, prior to issuance of building permits. Vibratory plows shall also be utilized when cuts are near the limit of the protective zone. As generally referenced on the April 26, 1995 Tree Preservation plan. -2- Future Landscaping Improvements In addition to the boulevard tree planting provided by the developer and clusters of planting along the western and eastern boundary of the site, future homeowners are strongly encouraged to install additional landscape plantings to their private residences. A quality landscape plan should consist of a variety of evergreen and deciduous shrubs, ornamental trees and over story trees. An appropriate mixing of plant material and variety of ground cover (grass, shrubs, nativelwild grasses) will enhance property values and wildlife habitat. In order to facilitate planting in Creekside, the subdivision has been generally classified into four planting zones. Each zone has characteristics which suggest certain plant materials be considered. The following zones and planting lists identify suggested plantings which will allow the homeowner to expand upon as each lot is personally landscaped. Suggested Residential Plantings: The site has been broken down into the following four zones. Zone 1 Area East of Road (Rear Yard) Eastern Side of Homes Zone 2 Areas East of Road: (Front Yard) West Side of Homes Zone 3 Area West o Road: (Front Yard) Eastern Side of Homes Zone 4 Area West of Road: (Rear Yard) West Side of Homes Suggested Residential Plantings: Zone I Plantings: Typical Overstory Trees: Upland (away from pond edge): - Red Maple - Hackberry - Green Ash - Honeylocust - Flowering Crab - Black Hills Spruce • Lowland (areas near ponds edge): - River Birch - Weeping Willow - Tamarak - Soft Maple -3- Shrubs • Upland: - Witch Hazel - Spring Glory Forsythia - Winged Euonymous - Amelanchier - Junipers - Sumac • Lowland: - Arrowwood Viburnum - Red Osier Dogwood - Scalet Elder - White Snowberry Zone 2 Plangtj • Upland: - Pin Oak - Red Maple - Paper Birch - White Ash - Colorado Blue Spruce - Scotch Pine • Shrubs: - American Cranberry Bush - Nanny Berry Viburnum - Lilac (Common and Hybrid) Zone 3 Plantin • Upland Trees: - Emerald Queen Maple - Red Maple - Littleleaf Linden - Block Hills Spruce - Indian Major Crab - Japanese Tree Lilac • Shrubs: - Miss Kim Lilac - Spring Glory Forsythia - Compact American - Cranberry Bush Viburnum - Anthony water Spirea - Bush Honeysuckle - Grey Dogwood -4- Zone 4 Plantings: • Upland Trees: - Red Oak - Pin oak - Red Sunset Maple - Hackberry - Colorado Green Spruce - Amur Maple - Princess Kay Plum - Red Splendor Crab Apple • Shrub: - Baileyi Dogwood - Intermedia - Spring Glory Forsythia - Puppurea - Common Purple - Winged Euonymous - Spreading Cotton Easter - Junipers • Suggested Planting Handbooks: - " Minnesota Nurseryman's Planting Handbook" - Plants for Outdoor Living - Available at all nursery's and garden centers. - " Landscaping for Wildlife - Minnesota Department of Natural Resources Natural Buffer Areas The trail, wetlands and storm water pond areas located along the eastern edge of Creekside are significant amenities for the residents and entire city population. Adjacent to the trail and or stormwater pond, residents are encouraged to allow native vegetation to become established in areas of 10' to 20' in width which will greatly enhance the natural beauty of the trail system. A natural buffer is strongly encouraged along the entire eastern edge of the residential homes to protect the natural areas from excessive use of fertilizer. Creekside residents will be encouraged to use conservative amounts of fertilizer to prevent nutrient rich runoff. -5- i 7 � M ► M J W a J M X f D \ m (D o m cn < cn 0 0m O c m 0 rn cn � w N z omm ' - -J O ;u - (O ;o --I �►'�m m m m mnc NO� m rnQ' -4 C � ;u 0C) mx� 00 cow z -u�rnz 0 x m D � Ln c) � � G7 0 0 E � z O \ M 0 D C-) � 0- m m 6z z - u co CDND m D ;b KOMc 0N� � II cnz .0 0 mom � M Z N cfl -i ;u � co - D 56 m - u Z gocW Il 0OO� o o O -<o � �m 0 o c� - u < o O N C7 m M OO <O m o- -� rn 0 z o U)n; Wo m Tt O --I --I O � m ; 4 D � c� z m m M r z O Z m m rJ m m� -1 -< -< m --I m m D H O O D (A ►� Co z r m m O � Z w N Cn W Z K -< m Z o 0 D OD �-� -1 O O 0 >0> �..� (n m \ > 0 0 D I N V m � o cn o m r n - n � m cD v C (A 0 C,4 � w o II cD II W N W O n O 0) Cn -P cn N ri MEMORANDUM DATE: April 27, 1995 Revised May 3, 1995 TO: John Dobbs, Heritage Development Company FROM: John Dietrich, RLK Associates RE: Reforestation Plan, Creekside Subdivision The reforestation plan which was approved in the preliminary plat subdivision identified 212* trees to be planted to compensate for the tree canopy removed and required canopy coverage of 30 %. The approved plan dated December 7, 1994 included the parcels of Block 2, Lots 8, 9, 10 and 11 in all of the calculations. The total acreage of these four lots is 2.46 AC. The City has requested the reforestation calculations be rerun based upon Lot 8, 9, 10 and 11 being purchased by the City as public open space. The net result of the revised calculation is identified below. Based upon the meeting of April 26, 1995, between John Dietrich and Bob Generous of the City, the revised reforestation plan will only apply if the Lots 8, 9, 10 and 11 are purchased by the City of Chanhassen.
