There are two underlying property owners, Mills Fleet Farm and the Savaryn Estate. The Mills site is 58.86 acres and the Savaryn property, which includes two parcels, has a total of 55.35 acres. A portion of the Savaryn property is located on the west side of Highway 41. This application omits this property but staff has included it because it is part of the tax parcel in discussion and it is integral to the PUD. The majority of the site has been farmed. There is a large wetland to the north and eastern edge of the site. Staff estimates the wetland to be approximately 12 acres. The three smaller wetlands that are found on the southeast comer of the site have been determined to be exempt because of past farming practices. The site has a rolling topography with a 40 foot change from the wetlands to the highest point. There is a home on the south comer of the property. The home is occupied, although there is inadequate utilities to the site (failing/failed septic and well). The site is bordered by two state highways. On the northwest portion of the site (Parcel A) is the Markert property (5.8) acres. The parcel has a home and is proposed to remain as a large lot. Future subdivision is possible. To the east is Outlot K of the Meadows of Longacres, the old Dolejsi property. Located in the middle of Outlot K is the American Baptist Group home that sits on ten acres. West on Highway 41 is the University of Minnesota Landscape Arboretum and the old Kordonowy property which is 60 acres. The Kordonowy site has been acquired by Westwood Church and will be going through site plan review in the near future. The site is currently zoned A2, Agricultural Estate. In the 1991 Comprehensive Plan, this area was given a Study Area status. It was guided as a part of the Highway 5 Corridor study in 1995. The land use considerations for this site are low density, office, institutional or medium density residential. This area is outside the current MUSA (Metropolitan Urban Service Area) and is not proposed to be brought in until the year 2000. The site will be accessed via the Hwy. 5 frontage road (West 78th Street) that is being proposed with the Hwy. 5 widening. The area east of the north/south road (Century Boulevard) was given an institutional, office or commercial land use (2.5 acres). This request proposes a PUD in order to mix the density and locate the commercial from the west to the east side of Century Boulevard. This project would also require a Comprehensive Plan Amendment. The Pulte Home request is for rezoning from A2, Agricultural Estate District to Planned Unit Development to accommodate a mixed use of 414 residential units and 3.7 acres of commercial zoning. There are 5 types of residences being proposed - 51 Club Homes, 83 Manor Homes, 104 Court homes, 144 Villages Homes and 32 Townhouses (rental townhouses). Arboretum Village September 1, 1999 Page 3 BACKGROUND The development of this site is being influenced by several important policies. These policies include the Highway 5 Corridor Study, the Bluff Creek Overlay District, the Comprehensive Plan, the City's Zoning Ordinance, and the Livable Communities Act. Following is a summary of each of these documents and its influence on the design of the subject site. Highway 5 Corridor Study The purpose of the TH 5 study was to select a preferred alignment for the northerly frontage road to review land use and zoning alternatives along the corridor and provide design guidelines. The purpose of the Overlay District as stated in the ordinance is to "be designed with greater sensitivity to the environment and of generally higher quality." The purpose of the district is to: a. "Protect creek corridors, wetland and significant stands of matures trees... b. Promotes high quality architectural and site design... c. Create a unified, harmonious and high quality visual environment... d. Foster a distinctive and positive community image...especially for the Highway 5 corridor which functions as the City's main entrance." The study proposed that the area north of the frontage road be given a land use designation of single family residential and the area south either medium family residential, institutional or office use. This request proposes lowering the medium density on the south side of the frontage road and raising the density north of the frontage road. The overall density would not exceed what is proposed in the comprehensive plan. This proposal is similar to what was done with the Walnut Grove Development. The plan also recommended the city establish the western gateway at TH 5/TH 41 by reinforcing the "orchard grid" of plantings. The plan does propose preservation of the two significant wooded area on the site as well as provide perimeter landscaping. Details on the building material are not available at this time. Bluff Creek Overlay District The Bluff Creek Corridor Study is a vision and planning document that has the following goals: a. Protection, Restoration and Enhancement'of Natural Resources b. Acquire land to create a continuous green along the creek from the Minnesota river to Lake Minnewashta Arboretum Village September 1, 1999 Page 4 c. Create development standards that manage upstream such as mixed or cluster development easements and alternative zoning d. Develop educational watershed awareness program e. Develop a Natural Resources Plan An overlay district was created for Bluff Creek with a primary and secondary corridor. The primary corridor boundary delineates a conservancy zone where undistributed conditions are desired. This is the area where any type of development and/or human activity directly impacts the morphological and biological characteristics of Bluff Creek. The secondary corridor boundary delineates a management zone. This is the area where development and/or urban activities directly affect the stream's upland ecosystem. The preservation and enhancement of this area will result in a better habitat and less strain on the stream. Management practices for this area focus on the preservation and enhancement of upland vegetation and the reduction of peak flows. A portion of this site falls within the primary and secondary zone. The Primary zone on the east side of TH 41 is largely in the area of the large wetland bordering the northern portion of the site and the trees around the south edge of this wetland. The other portion of the primary zone is on the west side of TH 41 which includes most of the Savaryn property. The City's Bluff Creek Overlay District states that no development shall occur within the primary zone. For this reason, staff believes that this area needs to be included within the PUD and a density transfer would be permitted to the east side to TH 41 out of the primary zone. The Bluff Creek Plan makes a couple of recommendations for this area including restoring the shallow marsh, and restoring the bird woods. An alternative was discussed for providing an additional underpass just for animals under TH 5 but this was not included in the design plans. Highway 5 Frontage Boulevard Much of the topography and the shape of the parcels is being driven by the location, necessary grading and pond location for the Frontage Road. The road is being constructed as a part of the upgrade from two to four lanes on TH 5. This road is being built and will be used as the by-pass during the construction of TH 5. The road also provides an east/west access alternative for local traffic so you would not have to get on Hwy. 5. The design of the road was also approved as a part of the Hwy. 5 corridor. The road is intended to be a boulevard with streetscape, lighting and a trail on the north. The cross intersection currently exists between Powers and Lake Ann Park. The construction of the road is necessary for this site to development. The frontage road construction will alter the topography by the amount of grading necessary, elimination of the exempted wetlands at the comer of TH 5/41 and tree loss. Arboretum Village September 1, 1999 Page 5 Livable Communities Act The city signed on the with the Livable Communities Act since 1995. The principles of the act state that the city support: 1. A balanced housing supply, with housing available for people of all income ranges. 2. The accommodation of all racial and ethnic groups in the purchase, sale, rental and location of housing within the community. 3. a variety of housing types for people in all stages of the life-cycle. 4. a community of will maintained housing and neighborhoods, including ownership and rental housing. 5. Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. 6. The availability of a full range of services and facilities for its residents, and the improvement of access to an linkage between housing and employment. This plan proposes predominately owner.occupied housing. There are 32 rental townhouses proposed which would meet the affordability standards for rental housing*. The applicant is proposing to finance the rental units using Minnesota Tax Credits. The owner occupied units will be 4 different types of products. The price range on these units range from $100,000 on the Village home to $220,000 on the Club Home. Any home sale under $128,000'* would be considered affordable under the Metropolitan Council standards. This project would be meeting some of the city affordable and housing diversity goals without city financial assistance. * 1999 Units renting for no more than 30 percent of household income for families with 50 percent or less of median income ($30,400max.) = units renting for $760 or less. ** 1999 Ownership housing costing no more than 30 percent of household income for families with less than 80 percent of metro area income ($48,640 max.) = $128,000 or less. Planned Unit Develol~ment The applicant is seeking a PUD in order to develop the entire site as one project. Because there are two underlying property owners, it has always been staff's opinion that this area is best developed as one parcel. The Savaryn parcel is very narrow and is encumbered by two wetlands and bisected by the frontage road and TH 41. The plan incorporates good planning principles by combining both parcels. The issue for the City to resolve is if this plan makes good use of the PUD principles. Having earlier noted that the primary zone is on the west side of TH 41 that density should be transferred to the east side unless the city wants to give a variance to this area and allow it to be developed separately. Arboretum Village September 1, 1999 Page 6 A subdivision was developed for the old Kordonowy site. This proposal, which included 57 acres, had 110 homes. This plan was never formally submitted and this property has now been sold to Westwood Church. Therefore, with the density transfer there will be no additional homes on the west side of TH 41. ANALYSIS Pulte Homes is requesting conceptual PUD approval for the subject site so they may begin the process of developing their project. They have a two year staging plan proposed. The conceptual PUD process requires following information: · Overall gross and net density. · General location of each major street and pedestrian ways. · Identification of each lot size and width. · Identification and extent of public and common open space. · Identification and type of land uses and intensities of development. · Staging and time schedule for development. The conceptual approval of the PUD gives the applicant no legal standing when it appears again for preliminary approval. Rather it is intended to give the applicant clear direction for the next level of review. Following is the staff review of the development. The project does not include all of the underlying property, most notably the easterly portion of the Savaryn development. Because this area in the primary zone of the Bluff Creek, staff is recommending that it be included in this proposal. The density is consistent with what would be permitted if the area was guided for medium density and be developed at 8 units an acre and the area guided for Iow density at 2 units an acre. (Staff estimates that this would yield approximately 425 units). The plan has 5 different types of units including 51 Club homes (one level town homes for active adults, 1220-2009 sq. ft., $145,000-$220,000), 83 Manor homes (split level town homes with basement, 1200-1,600 sq. ft., $145,000-$165,000) 104 Court homes (two story town homes 1,100-1,300 sq. ft., $112,000-$130,000) 144 Village Homes (two story town homes with tuck under garage, 900 -1,150 sq. ft., $100,000-$110,000) and 32 Rental units. Staff supports the diversity within the types of units. The Village Home is a new product that has not been built in the city. Information regarding the material is not well defined. Staff is recommending that each housing area become a neighborhood with some distinct characteristics. The commercial development needs to be further defined with neighborhood uses only. This too needs to have materials that are residential in nature. Arboretum Village September 1, 1999 Page 7 The site gains access off the frontage road and will have one internal road. Staff is recommending that this street be extended to the north. Staff is recommending that this street be eliminated. The Village Court homes area has poor circulation. Staff is recommending that a road be tied into the two access points on West 78th Street to give a better sense of order. The amount of grading is not shown on the plan. Staff would like to see the amount of grading kept to a minimum. Trails connect the entire project. There is a remnant piece of property north of the wetland (2.5 acres). This property could be sold to the adjoining property owner or be left as open space. Landscaping and Tree Preservation Existing tree cover is located in the south central part of the property along Highway 5 and also around the current home site. Tree lined fence rows extend northwards from these two areas. The jewel of the property exists on the west side of Highway 41. This is a 100% wooded triangular piece forested primarily with large sugar maples. Oaks and lindens are interspersed and all are mature trees. It is an outstanding remnant of the maple-basswood forest that once covered the city and deserves every effort by the city for complete preservation. It is also located within the primary zone of Bluff Creek and was noted as a prime candidate for preservation due to its superb health. Current canopy coverage has not been calculated, however conceptual plans show the fence rows and trees near the existing home as being removed. To their credit, the developers are proposing to preserve the larger wooded area near Highway 5 and the tract across Highway 41. This would benefit the area greatly by providing a natural area within an intensely developed one and some buffering and scenic views from Highways 5 and 41. Staff strongly recommends that the applicant be required to maintain these preserved areas when the preliminary plans are submitted. Landscaping priorities for Arboretum Village will be boulevard trees along all streets and buffer yard plantings along Highway 5, Highway 41 and the north frontage road that will run through the development. Additionally, common area plantings and individual unit landscaping will be required to use varied and interesting plant materials. In the Village Homes common areas behind the units, increasing the number of tree plantings would create a more attractive and private area. In a sense, 'rooms' could be created that would provide the residents with a sense of place and unique interest. According to the conceptual plan, the applicant appears to comply with all of the general issues in the proposed landscaping. Specific changes and alterations will be addressed at the time of preliminary plan submittal. Wetlands There are two wetlands on this site. Both are connected hydrologically but have different characteristics. To the north is an Ag/Urban wetland which is part of a 40-acre wetland which Arboretum Village September 1, 1999 Page 8 extends from Trunk Highway 41 to Galpin Boulevard on the east. There is a smaller wetland of approximately 7 acres in size which is a DNR protected wetland (No. 10-209W). This wetland feeds into the larger Ag/Urban wetland and is part of the wetland complex which is the headwaters for the Bluff Creek. The Ag/Urban wetland to the north is in very poor condition. Past agricultural activities have taken row crops to the edge of the wetland. This wetland is dominated by reed canary grass and there is not a diversity of species remaining on the south side. There are some trees on the north side but nothing of high quality or native in nature. The wetland directly east of the property is listed in some City documents as Ag/Urban and in others as natural. After visiting the site and looking at the topography and vegetation, staff would have to say that it is leaning toward an Ag/Urban wetland because of recent (within the last 20 years) agricultural practices. Very few of the remaining buffers of trees and native plants remain around the rim of the wetland. It has been row-cropped very close to the wetland edges and is dominated by reed canary grass which is choking out cattails along the edges. We saw some stinging nettle at that site. The trees that are there are box elders, willows and willow shrubs. We did find on the north side of the wetland some Arrowhead, sedges, cattails, duckweeds, ferns, willows and tall willows. Along this proposed development, the wetland is in a state of great influence through agricultural activities. Staff would tend to classify this wetland as Ag/Urban at this time. As mentioned previously, these wetlands are connected and were part of the Bluff Creek study for a possible wetland restoration site. Two years ago when we were looking at sites for a Board of Water and Soil Resources grant to fund some restoration projects, we had looked at this site as a restoration possibility. However, there was opposition from the Lundgren neighborhood to the north and these plans were put on hold. Another factor in holding the project is that we had no easements over the south end of this particular wetland. Now that this project is becoming before the City, staff should reevaluate the possibility of doing the wetland restoration project and try to make a full-scale restoration project in addition to this project. Another aspect of the proposed project was to put a control structure in along the berm to act as a current or overflow barrier which controls the water level in these wetlands. The normal water level now is 959.7 and high water level is 960.3. With this project we would put in a control structure with the ability to manipulate water levels. We would increase the normal water level 0.3 feet to 960 and the high water level would be 960.8. These are very subtle changes but this would provide an environment in which the reed canary grass could no longer survive. If we raise the water level we would drown out a large majority of the reed canary grass and once it had died out we could again lower the water level to allow native wet meadow prairie plants to reestablish themselves and create a more diverse plant community and also encourage wildlife through this area as recommended by the Bluff Creek Management Plan. Wetland Setbacks / Arboretum Village September 1, 1999 Page 9 The setbacks as indicated on the plan appear to be too close to the wetlands. While Ag/Urban wetlands require a 1 O-foot buffer in addition to a 40-foot setback, I believe this area should be on the south edge of the proposed bituminous path. That way you don't have a bituminous path in the buffer zone which would defeat the purpose of having a buffer zone. There are no established DNR setbacks for protected wetlands; however, the City has different wetland setback requirements for Ag/Urban than natural wetlands. With natural wetlands there is a 20- foot buffer in addition to the 40-foot setback so we are looking for a 60-foot setback along the wetlands to the east. Criteria must be established to determine which wetland classification best suits this area before a setback can be established. Inspections and Fire Marshal Comments The Fire Marshal is recommending a possible grid system to determine better street addressing. Also, location of fire hydrants and fire code issues need to be addressed (see letter dated Aug 23, 1999 from Mark Littfin). The Building Official has addressed accessibility requirements on a percentage of the units and the type of occupancy (see letter dated Aug 19, 1999 from Steve Torell). Park and Trails The Park & Recreation Commission reviewed the Conceptual PUD for Arboretum Village on August 24, 1999. Mr. Mark Guenther represented Pulte Homes at the meeting. Todd Hoffman, Park & Recreation Director, presented the staff report. Commissioner comments focused on the preservation of the wooded lots, provision of expanded "tot lot" or play areas and the importance of the trail connections. Please note that the inclusion of trail/sidewalk connectors from the Village Homes west to Highway 41 and south to Highway 5 were discussed. The applicant agreed that these pedestrian routes are important and will add them to the plan. Upon conclusion of discussion that evening, Commissioner Karlovich moved that the following conditions of approval be met. 1. Preservation of the wood lots on the property. 2. Construction of the interior trails as association connectors at the applicant's expense. Construction of the wetland trail as a comprehensive trail segment with appropriate public easements being granted and trail dedication dollars used for construction. 4. Plans be submitted for the manor home and rental townhouse tot lot prior to approval. Arboretum Village September 1, 1999 Page 10 o The tot lot/play area in the court homes be expanded to 2 to 2 ½ acres in size be centrally located and be connected to appropriate pedestrian routes. GRADING The site mainly consists of rolling terrain that was employed in agricultural practices in the past. There are a couple of wooded areas and isolated wetlands. Existing wetlands on site are proposed to be impacted by development. A wetland alteration permit will be required. Most of the wooded areas are being retained. Tree conservation/preservation easements should be required to preserve these woodland areas indefinitely. The site will be impacted by the future upgrading of Trunk Highway 5 which is tentatively scheduled for 2000-2002. MnDOT has proposed to upgrade TH 5 to a four lane highway as well as construct the east/west frontage road (West 78th Street) from TH 41 to Lake Ann Park. Depending on MnDOT's phasing, staff is anticipating construction will commence approximately May, 2000 with the frontage road being constructed initially. The preliminary phasing plan includes redirecting traffic from Hwy. 5 onto the new West 78th Street frontage road late fall 2000. With all the proposed construction activity and rerouting of traffic, access to the site will be very difficult. The applicant should work closely with MnDOT in coordinating street grades and storm ponding issues throughout the site. Detailed grading, drainage, erosion control and tree removal plans will be required with the preliminary plat submittal. Berming in accordance with city codes need to be provided along West 78th Street, Century Boulevard, TH 41 and TH 5. In conjunction with the Hwy. 5 upgrade, no noise abatement is proposed. Therefore, it is very important for the applicant to incorporate berming or other noise abatement features to this project. MnDOT should also review the grading plans to ensure compatibility. Both permanent and temporary easements will be required by MnDOT with construction of TH 5 This will result in a loss of developable land. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with detailed haul routes and traffic control plans. UTILITIES Currently, there is no municipal sewer or water service available to the site. In conjunction with the upgrade of TH 5, MnDOT and the City are coordinating to extend water service along West 78th Street from Galpin Boulevard. The timing of MnDOT's project is not controlled by the City. Staff's conservative estimate is that the earliest water would be available is late fall or winter of 2000. Sanitary sewer is located east of Galpin Boulevard just north of TH 5. Sanitary sewer will be extended across Galpin Boulevard with the TH 5 project. Currently there are no plans on extending this sewer line to service this site. The City has received a petition from a property Arboretum Village September 1, 1999 Page 11 west of TH 41. The applicant also needs to submit a petition to the City for extension of the sanitary sewer as soon as possible in order to consider a project in the year 2000. If the sewer project was ordered by the City Council, it would not be available for connection until late fall of 2000 at the earliest. Any delay in submitting a petition for sanitary sewer improvements will result in a corresponding delay in project completion. In conjunction With utility extensions, the project will be subject to assessments accordingly. Utility improvements throughout the site will have to be constructed by the applicant in accordance with the City's latest edition of Standard Specifications and Detailed Plates. Detailed construction plans and specifications will be required at each phase of development at the time of final plat. A Comprehensive Utility Plan will be required at the time of preliminary plat submittal for review and approval. The applicant will also be required to enter into a PUD Agreement/development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and conditions of final plat approval. The utility system, upon completion, will be owned and maintained by the City. Appropriate drainage and utility easements will need to be dedicated on the final plat for those utilities which fall outside the dedicated right-of-way. DRAINAGE A storm water management plan will need to be developed in accordance with the City's Surface Water Management Plan at time of preliminary plat submittal for review and approval. The applicant should work closely with MnDOT to consolidate/minimize piping and ponding systems. Storm water ponds shall be designed and constructed with NURP standards. Pre and post storm water calculations including drainage area maps for a 10 year and 100 year, 24 hour storm events, need to be prepared and submitted to the City for review and approval in conjunction with the preliminary plat submittal. Development of the storm water management plan may result in loss or relocating of units due to storm water pond locations. The large storm water retention pond located at the southwest comer of Century Boulevard and West 78th Street will be constructed and owned by MnDOT in conjunction with TH 5 upgrade. This pond may be able to accommodate runoff from a portion of the site. The plans propose retaining walls as well as a fountain system in the storm water ponds. These amenities may not be permitted by MnDOT. The applicant should contact MnDOT accordingly. Another storm water pond is proposed in the northeast comer of TH 41 and 5. Given the close pt:oximity to the intersection, staff believes the noise from the highways will be a major issue. Staff believes that a combination of intense landscaping and berming and reduced pond size would be a greater benefit for noise abatement then an amenity such as a pond. Staff recommends the applicant look very closely at revising this area to provide additional noise abatement features. Arboretum Village September 1, 1999 Page 12 Additional storm water ponding may be required in the northerly portion of the site which will result in the loss of units. Storm water ponding should also include drainage from Parcel A which is located in the northwesterly portion of the site if feasible. Soils throughout Chanhassen have a very high moisture content. Groundwater has been observed in other projects in the area. Seasonal and annual fluctuations of the groundwater should be anticipated. Staff recommends construction of drain tile systems behind the proposed curbs to intercept and convey household sump pump discharge that would typically be extended to the street. The City has in the past experienced that the discharge of sump pumps in the streets created hazardous conditions for the public, i.e. icy conditions in the winter as well as algae buildup in the summer. STREETS Conceptually overall the street system is fairly well designed. West 78th Street which is the major east/west collector street through the site appears to conform with MnDOT/City plans. Timing of West 78th Street is of major concern. MnDOT has tentatively planned to begin the TH 5 project in early 2000 with completion in the year 2002. The preliminary phasing plan for TH 5 is to construct West 78th Street from TH 41 to at least Galpin Blvd. and use it for a detour route while TH 5 is being reconstructed. West 78th Street is classified as a collector street in the City's Comprehensive Plan and designated as an MSA route. The street will be constructed 36' wide face to face with multiple auxiliary turn lanes and traffic delineation/medians at the intersections of Century Boulevard and TH 41. The turn lane medians will limit access points to the site. The plans propose a driveway access to serve 4 units north of West 78th Street and east of Century Boulevard. Staff believes this access point should be eliminated and relocated to the proposed interior street system. This will result in shifting a number of units to facilitate the driveway. Access to the commercial parcel located in the southeast comer of Century Boulevard and West 78th Street is also a concern. There is additional land just to the east of the commercial site that will mostly likely develop in a similar land use. Due to medians on both Century Boulevard and West 78th Street, access to the site will be very limited. Staff believes it may be feasible to provide a right-in/right-out if at all on Century Boulevard and a full access towards the easterly side of the commercial parcel. This full access will eventually have to be shared with the future development of the parcel to the east. Cross-access/maintenance agreements should be recorded against the parcel to provide future access needs for the adjacent parcel. Staff is also concerned with a number of areas where driveways will be too close to intersections or intense traffic circulation. In these areas staff believes that the units should be redesigned with driveway access points relocated to the interior lower volume street system. Staff does not Arboretum Village September 1, 1999 Page 13 believe that units will be lost as a result of this. However, reconfiguration of or different units styles may be required to achieve this. Staff assumes that the wider street systems proposed would be the public streets and the other streets would be considered private. Staff believes that the southerly portion of the project needs to be served by a public loop street similar to the area north of West 78th Street. This may result in loss of units due to additional right-of-way dedication of a public street. Public streets will required a 60' wide dedicated right-of-way and an 80' wide dedicated right-of-way for West 78th Street. Access to the private streets should be addressed with cross access maintenance agreements or covenants. The public streets shall be constructed in accordance with City requirements for urban street section which is 31' back to back with concrete curb and gutter. In areas where turn lanes are proposed, the right-of-way and streets will need to be wider. The applicant is proposing private streets to serve the villas and cottage homes. The proposed private streets are similar to the Walnut Grove development adjacent to Galpin Boulevard north of Trunk Highway 5. City code requires a 24-foot wide minimum private street with no parking unless the street serves less then four dwellings at which time the street may be 20-feet wide. The private streets will need to be constructed to meet 7-ton per axle weight design criteria. Cross access and maintenance agreements will need to be developed and recorded against the benefited parcels. Deadends must provide a turnaround acceptable to the Fire Marshal based upon applicable Fire Codes. If on street parking is desired, a wider street section, minimum 28' wide, should be designed. A private street system will need to be located within a strip of property at least 40' wide. This should be adequate width to also dedicate the required drainage and utility easements over the proposed utilities to service the development. Detailed construction plans and specifications for both the private and public streets will be required prior to final plat consideration. The public streets shall be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The private streets shall be constructed to support 7-ton per axle design weight in accordance with the City Code 20- 1118 "design of parking stalls and drive aisles." In conjunction with TH 5 project, a trail system will be constructed along TH 5 between Hwy. 41 and Century Boulevard as well as along the south side of West 78th Street. The applicant has incorporated these trail systems into their conceptual plans. A number of additional trails have been proposed by the applicant. Staff believes a number of these trail systems should be revised or eliminated. A sidewalk/trail system should be incorporated into the street system which will connect to the trail system on Hwy. 5 and West 78th Street. The trail Arboretum Village September 1, 1999 Page 14 proposed along the wetland on the easterly portion of the site should be eliminated and replaced with a sidewalk/trail system along the north-south street. Staff has reviewed the street extensions to the adjacent parcels in conjunction with this development. Staff believes that the north-south street will not need to be extended in the future to the east. This will allow for the street to be shortened and a cul-de-sac to be constructed which will minimize grading, tree loss and impact to adjacent wetlands. The other parcel, Parcel A, shown on the plans is proposed to be served by a public street which will terminate at the property line. The alignment of the street appears to allow Parcel A to develop in a fashion conducive to the site features.

We at Pulte Homes look forward to providing the residents of Chanhassen with quality housing within your fine city. Please find attached twenty six (26) sets of the submittal package requirements for General Concept Plan review for a planned unit development. I look forward to working with you during the review process. The Arboretum Village plans represent a request for rezoning from A2 - Agricultural Estate District to Planned Unit Development to accommodate a mixed use of 414 residential units within homeowner association greenspaces and 3.7 acres of commercial on approximately 82.4 acres for a density of 5.14 units/acre. Park dedication is proposed to be in the form of cash. The 32 rental townhomes and the 13 acres west of C.S.A.H. 41 will remain in ownership of James Deanovic, the underlying contract holder on the Savaryn property. Details of those areas will be addressed by Mr. Deanovic. However, Pulte's request does not require any density transfer from the property west of C.S.A.H. 41, per our calculations. Proposed timing for the development, as indicated on the Staging Plan, is for Phase One to begin Spring, 2000, timely with the MNDOT project and Phase Two to begin Summer, 2001. Please do not hesitate to call me if you have any questions or comments on this matter. We look forward to the 8/1/99 Planning Commission and the 8/27/99 Council meetings.

Recommendation5 This section recommends a series of projects and practices necessary to achieve the vision and goals of the Steering Committee. V,A N~turc~l Resource5 Recommendations in this segment focus on restoring wetland communities and re-establishing big woods forest species on upland areas. This segment of the Bluff Creek Corridor and the sites addressed below are shown in Figure 9 on page 45. The corridor boundaries are defined by existing wetlands and recommended 300 foot buffer strips along either side of the Bluff Creek. The following plan of action is recommended: · Site la - Shallow Marsh Restoration This site is within an existing wetland located between Hazeltine Boulevard and Galpin Avenue. The plant community is dominated by reed canary grass with small amounts of nettle, willows, jewelweed, elm and boxelder present. £o oChjeVe the vision. Wetland restoration of this basin will involve the reestablishment of a mixed emergent marsh wetland community. Mixed . emergent marsh are typically dominated by a variety of emergents. Different types of bulrush commonly occur in the deeper portion of the wetland and are dominants. This community changes into a fringe of wet meadow grasses including prairie cord grass, spike rushes and a variety of sedges. P&3¢ 64 ii II II !1 ji l" l" l" l" l" l" l" l" l" I" The hydrology of this wetland has been altered by a ditch which exists in the southeast portion of the wetland. Artificial basin drainage has altered the hydrology and caused a shift of plant species tolerant of standing water or saturated soil to reed canary grass, Which grows best in seasonally flooded conditions. Reed canary grass is a colonizing, invasive specie which out competes native species following disturbances from agricultural use, drainage, filling, siltation and others. Its aggressiveness allows the formation of persistent monotypic stands of the species. Wildlife values of the wetland are reduced from a loss in plant diversity and cover that other emergents provide. The wetland likely existed as a higher quality emergent marsh prior to the drainage. Restoration of this wetland will involve the removal of reed canary grass and restoring the hydrology and mixed emergent marsh communities to the wetland. Removal of reed canary grass often needs to include herbicide treatment in combination with a prescribed burn (when possible). This, combined with increased water levels, should remove reed canary grass. It may not be practical to treat the entire site with herbicide or to do a prescribed burn. The areas that will have sustained water- levels of 12 inches should not need to be treated with herbicide or burned because of reed canary grass's intolerance to sustained water levels. Areas with less then 12 inches of sustained water levels will need to have some type of treatment to remove the reed canary grass, Restoration of the hydrology could be accomplished with construction of a control structure at the wetlands outlet. The following considerations need to be addressed before the control structure is constructed: I. Flows Special considerations need to made to insure the control structure discharge capacity will be sufficient to handle the existing flows. 2. The control structure should not allow bypassing, 3. Consider potential conflicts with adjacent lands 4. Create an appropriate hydrologic regime for' the restored wetland If feasible, a control structure with potential for' water level regulation is preferred. It allows maintenance on the outlet and control structure when needed ai~d will help control plant succession - a benefit to waterfowl. Revegetation of the site may occur naturally over time. If quicker and more dependable results are wanted then the area should be planted and seeded root stock can accelerate the process, An economical solution is Btt.lff Cree~ Wc~ter~ed N~ttlrc~l Re~ot~rce~ Ma~c~geme~t Pl~l~ to allow the deeper' areas to revegetate naturally and seed the saturated soil areas. It is important to establish plants quickly in the saturated soil zone to reduce the chances of reed canary grass coming back to these sites. · Site I b - Restoration of Big Woods Vegetation Buffer strips of 50 to I00 feet should be established along Bluff Creek and along all wetlands within the corridor. A mixture of tree and shrub species native to the Big Woods forest should be established within this buffer with lowland hardwood species on wetter sites and maple-basswood or oak forest species planted on upland sites. Please see a partial listing of tree and shrub species for Big Woods forest communities in Appendix C, These plantings should be linked to existing wood lots wherever possible to create a continuous travel corridor for wildlife. For maximum benefits to wildlife, interior portions of the corridor should not be visible from outside the corridor'. · Site lc - Highway 5 Wildlife Underpass One of the biggest impediments to wildlife movement within the Bluff Creek Corridor are highway crossings, Highways fragment wildlife habitat and disrupt animal movements. Where highways cross migration routes or travel corridors of large mammals such as white-tail deer, mortality can be high and damage to vehicles and injury to humans frequent. The' proposed recreational trail underpass near the new high school can be designed to encourage safe wildlife movement under Highway 5. To make the underpass attractive for wildlife, a bridge or a large culvert should be used that is directly linked to vegetation within the corridor. Ideally, dense, brushy vegetation such as conifers and shrubs should extend from within the corridor to the entrance of the underpass. Fencing should be placed along either' side to funnel wildlife into the underpass, Fencing near the ground should be of fine mesh and partly buried for smaller mammals reptiles and amphibians.

The Highway 5 Corridor and the development within it will be major factors influencing the visual and environmental quality of the community as a whole. Due to the intensity of land uses, the Highway 5 Corridor represents the heart of Chanhassen as well as its dominating image of those passing through the community. Development in the corridor must be designed with greater sensitivity to the environment and of generally higher quality than might have occurred in the absence of specific standards. The purpose of the District is to: (a) Protect creek corridors, wetlands, and significant stands of mature trees through use of careful site design, protective easements, sensitive alignment and design of roadways and utilities, incorporation of natural features, landscaping and massing of trees that enhance existing natural features and views, and the practices delineated in the City's Best Management Practices Handbook. (b) Promote high-quality architectural and site design through improvement development standards within the corridor. These standards govern site planning, placement of building masses, use of materials, and the like enable the City to enhance what otherwise might result in Iow quality strip development. (c) Create a unified, harmonious, and high-quality visual environment throughout the corridor, thereby identifying it as a special place with a unique identity within both the City and the Twin Cities region as a whole. (d) Foster a distinctive and positive community image, for the City as a whole and especially for the Highway 5 Corridor, which functions as the City's main entrance. Sec. 20-1451. Intent. The City intends that all development within the district should strive toward the highest level of quality in both design and construction. The criteria by which new development in this district shall be judged are as follows: (a) Consistency with all provisions of the Comprehensive Plan, as amended from time to time; the Surface Water Protection Program; all provisions of the Zoning Ordinance and Subdivision Ordinance not specifically overridden by the provisions of this district; and all other applicable land use regulations. 3 (b) Preservation of the natural conditions found on each site to the greatest extent ' possible, through minimized removal of trees and other vegetation and soil, minimized site grading, and application of the practices found in the City's Best Management Practices Handbook. (c) Establishment throughout the district of harmonious physical and visual relationships among existing, new; and proposed buildings, open spaces, natural terrain, and plant materials and placement with the intent of creating a unique and unified appearance for the entire corridor. (d) Use of appropriate materials, lighting, textures, colors, and architectural and landscape forms to create a unified, high:quality design concept for each site that is compatible with adjacent and neighboring structures and functions, including but not limited to natural areas, City-owned property, and vacant land subject to future development in accordance with the Comprehensive Plan. (e) Creation of unified site designs, each with a sense of internal order, that provide desirable environments for site users and visitors and the community as a whole and that consider all site elements including: the relationship of buildings to surrounding landforms; grading; architectural design; building, parking and loading dock orientation; building height; use of man-made materials, including paving; site furnishings (lighting, outdoor seating, signage, etc.); landscaping (retention of natural vegetation, plant selection and placement, retention and incorporation of water features, etc.); and other visible outdoor site elements. (f) Creation of a suitable balance between the amount and arrangement of open space, landscaping, and view protection and the design and function of man-made features on the other. Achieving this balance shall take into account screening, buffering, size and orientation of open spaces, personal and property security, localized wind and solar effects, and protection of important public ways. (g) Provision of safe and adequate access to and from sites giving ample consideration to the location and number of access points from public streets, the safety and convenience of merging and turning movements, and traffic management and mitigation. (h) Provision of on-site vehicular, bicycling, and pedestrian circulation by way of interior drives, parking areas, pathways, and walkways adequate to handle anticipated needs and to safety buffer pedestrians and cyclists from motor vehicles. Ample consideration shall be given to the width of interior drives, internal traffic movement and flow, separation of pedestrian, cycling, automobile, and delivery traffic, and the safe convenient, and practical arrangement of parking spaces. (i) Adequate separation and protection of each site from adjacent properties, access boulevards, and Highway 5 and vice-versa, through reasonable provisions for surface water 4 drainage, sound and sight buffers, view protection, privacy, and other aspects of design that may not be specifically covered by these or other regulations but are found to have significant effect on any or all of the properties and roadways. Sec. 20-1452. District Application. The "HC-I" district shall be applied and superimposed (overlaid) upon all zoning districts as contained herein as existing or amended by the text and map of this ordinance.

A solid wall unrelieved by architectural detailing, such as a change in materials, change in color, fenestrations, or other significant visual relief provided in a manner or at intervals in keeping with the size, mass, and scale of the wall and its views from public ways. A change in texture alone is not sufficient to meet this requirement. Materials or construction methods used for One aspect or portion of a project that are significantly lower in quality than those used for the balance of that project, such that this one aspect or portion is or rapidly becomes an eyesore or detriment to the project as a whole. A distinct and different material or combination of materials for each exposed exterior wall. No more than two (2) principal materials or two (2) principal combinations of materials should be used to construct any one building. Addition of other materials for accent use is permissible. As building element, combination of elements, or another site structure that acts as a conspicuous building emblem or signature. Examples include single garish elements (e.g., orange roofs); use of bricks, blocks, or tiles to mm a wall into an outsized sign or logo; and other attempts to use a building or wall as an advertisement.

The Bluff Creek Watershed Area and the development within it have a major influence on environmental quality in the City and the region. Development within the corridor must be designed with utmost sensitivity to the environment and the development pattern must be of a quantity and quality other than what might occur in the absence of specific standards. The purpose of the District is to: (a) Protect the Bluff Creek corridor, wetlands, bluffs, and significant stands of mature trees through the use of careful site design, protective covenants, sensitive alignment and design of roadways and utilities, incorporation of natural features, landscaping, techniques outlined in the City's Surface Water Management Plan, and the practices delineated in the City's Best Management Practices Handbook. Co) Encourage a development pattern that allows people and nature to mix spanning multiple ecosystems. Development in the corridor should be ecologically designed and built around natural features such as trees, wetlands, and bluffs. Significant natural features should impact development rather than development impacting significant natural features. The natural qualities of the corridor should be preserved to ensure sufficient habitat area for wildlife. (c) Promote innovative development techniques such as cluster development and open space subdivisions to measurably reduce the amount of impervious cover compared to traditional development practices resulting in significant portions of a site being retained as permanent, protected open space. (d) Foster the creation of a greenway connecting Lake Minnewashta Regiona1 Park and the Minnesota River Valley. The greenway will serve as an uninterrupted pedestrian trail, bikeway system, and wildlife corridor affording opportunities for recreation, education, physical fitness and non-motorized Iransportation. 3 (e) Encourage cost effective site development. Open space design practices can reduce infrastructure engineering and construction costs because of lot configurations, shortened streets, and reduced utility runs Long term cost savings can also be realized by the City of Chanhassen associated with infrastructure maintenance costs. (f) Implement the policies and recommendations found in the Bluff Creek Watershed /qamral Resources Management Plan. The terms, definitions and appendices found in the Management Plan are incorporated herein. See. 20 - 1461 Intent. The City intends that all development within the district including commercial, industrial and residential uses should blend into the natural environment while protecting Bluff Creek and sensitive land areas abutting and in the vicinity of the watercourse and its tributaries. The criteria by which new development in the district shall be judged are as follows: (a) Consistency with all provisions of the Comprehensive Plan which includes the Bluff Creek Watershed Natural Resources Management Plan, as amended from time to time; the Surface Water Management Plan; all provisions of the Zoning Ordinance and Subdivision Ordinance not specifically overridden by the provisions of this districti and all other applicable land use regulations. (b) Preservation of the natural conditions found in the Primary Zone and to the greatest extent possible, preserving significant resources and minimizing impacts in the Secondary Zone through cluster development and other practices which minimize the removal of vegetation, minimize site grading, and application of practices found in the City's Best Management Practices Handbook. (c) Creation of a suitable balance between the amount and arrangement of open space, landscaping, view protection, bluff protection, and vegetation protection and the design and function of man-made features. (d) Creation of an interconnected open space network that preserves migratory patterns for wildlife. (e) Creation of an interconnected open space network that provides recreational and educational opportunities for people. See. 20- 1462 District Application. The BCO district shall be applied or superimposed (overlaid) upon all zoning districts as contained herein as existing or amended by the text and map of this ordinance. The regulations and requirements imposed by the BCO district shall be in addition to those established for districts which jointly apply. Under the joint application of the districts, the more restrictive requirements shall apply. 4 Section 20-1463 Conditional Use Permits.

Sec. 20-1464 Boundary Delineation. (a) Generally. Primary and Secondary Zones shall be subject to the requirements established herein, as well as restrictions and requirements established by other applicable city ordinances and regulations. The Bluff Creek Watershed regulations shall not be construed to allow anything otherwise prohibited in the zoning district where the overlay district applies. Co) Boundaries; maps. The Primary and Secondary zones include land that is generally defined in this article and in the Bluff Creek Watershed Natural Resources Management Plan. Boundaries as established by officially adopted city maps shall be prima facie evidence of the location and type of watershed zone. The official maps shall be developed and maintained by the planning department. The applicant shall provide appropriate technical information, including but not limited to, a topographical survey, flora and fauna survey and soil data deemed necessary for the city to determine the exact watershed zone boundary. The planning director shall make a determination to maintain the officially designated watershed zone boundary or if the boundaries need to be corrected on city plans and maps based upon the data that is supplied. Data for watershed zone delineation shall be generated and provided by a qualified professional specializing in watershed management, environmental science or other related profession. The applicant may appeal the planning director's determination of the watershed zone boundary and type to the city council. Sec. 20-1465 Impervious Cover and Slopes. To the greatest extent possible, all development shall minimize the amount of impervious surface by clustering development, using common access drives and utility corridors and minimizing building footprint size. Roads, walkways, bike trails, and parking areas must be designed parallel to natural contours with consideration to maintaining consolidated areas of natural topography and vegetation. Management of surface run-off caused by impervious cover shall be designed using practices delineated in the city's Best Management Practices Handbook. Within the Secondary Zone of the BCO district, areas with average slopes exceeding 25% shall be preserved in their natural state and maintained as permanent open space. Areas with average slopes less than 25% but greater than 10% shall not exceed an impervious surface coverage of 25%. Impervious coverage for areas where average slopes are less than 10% shall be governed by the underlying zoning district. Sec. 20 - 1466 Bluffs. Bluffs shall be preserved as provided for under Article XXVIII. 5 Sec. 20-1467 Site Views. Through environmentally sensitive design such as "terrain adaptive architecture" (see Figure 1.), landscaping and site planning, site views both to and from the BCW district shall be preserved and enhanced to the greatest extent possible so as to maintain views that reflect and protect the natural beauty of the BCO District. Special attention should be given to views that are highly accessible to the public such as scenic overlooks, ridges and trails. Clustering of 'development away from natural overlooks is encouraged.

Density clustering shall be allowed as a tool to facilitate cluster development within the BluffCreek corridor. Density clustering may be used in areas where portions of the site are unsuitable for development because of the location of the Primary Corridor. Density clustering shall not be allowed for areas that are otherwise considered unbuildable due to wetlands, lakes and other areas not suitable for building purposes. In areas where density clustering is applicable, density may be transferred to unconstrained parts of the site within land included in the Secondary Corridor, subject to the restrictions of this ordinance, and within land lying outside of identified corridor areas. Additionally, the following conditions may qualify for density clustering: a) Land slopes in the Secondary Zone that exceed 25% on average. b) Land in the Secondary Zone containing stands of native trees. Land with suitable natural habitat to endangered or threatened species or a fragile ecosystem.

Single-family attached, cluster, zero lot line, and similar dwelling types shall only be allowed on sites designed for low, medium or high density residential uses by the City of Chanhassen Comprehensive Plan. Sec. 20-1470 Namrat t.q(.abSta'i Preselx. ration. a) Natural habitat areas within the Primary Zone shall be preserved as permanent open space. Any development that occurs shall be directly related to the continuous greenway along the creek from the Minnesota River to Lake Minnewashta as outlined in the Bluff Creek Watershed Natural Resources Management Plan. b) Where possible, any disturbances of natural habitat areas within the Secondary Zone shall be avoided. Any alterations to the natural habitat within the Secondary Zone shall adhere to the practices delineated in the city's Best Management Practices Handbook. Se~ 20-1471 Natural Habitat Restoration Plan If natural habitat areas located within the Secondary Zone will be disturbed during any stage of development, the applicant shall submit a detailed plan identifying the resources that will be disturbed and a corresponding restoration and/or mitigation plan. Such restoration might include wetland mitigation and replanting of habitat significant to endangered and threatened species. 8 See. 20 - 1472 Open Space Requirements. Open space shall comprise 100% of the area located within the Primary Zone. The City will establish the boundary for the Primary Zone using data proVided by the applicant. See. 20 - 1473 Structure Setbacks. All structures shall be setback a minimum of 40 feet from the Primary Zone. No disturbance or,he site shall occur within the first 20 feet of such setback.
