Section 20-411, Placement of Structures. Section 20-615, Lot Requirements and Setbacks. Chapter 20, Article II, Division 3. Variances Chapter 20, Article XII, “RSF” Single-Family Residential District SUGGESTED ACTION "The Chanhassen Planning Commission approves a 10-foot averaged wetland buffer for the construction of a sunroom, subject to the conditions of approval, and adopts the attached findings of fact and decision." SUMMARY The applicant is requesting a variance to permit a 10-foot averaged wetland buffer in order to facilitate the construction of a 210 square-foot sunroom. The applicant is proposing to restore a significant amount of wetland and provide a buffer where no buffer is currently present in order to offset the 3 impact of the requested variance. Granting this variance would also remove the nonconforming status of the existing home by brining it and the proposed addition into compliance with the required 40-foot primary structure wetland setback. BACKGROUND Country records indicate that the house was constructed in 1963. On June 11, 2001, the City vacated a portion of the roadway easement adjoining the property and designated the front lot line as the east property line, the rear lot line as the west property line and the north and south lot lines as side lot line. On July 3, 2001, the City issued a permit for a detached garage. On October 22, 2015, the City issued a demolition permit for a pool (pool appears on 1969 aerial photos and predates zoning code). Numerous other permits for interior maintenance and improvements are on file. The previous owners of the property filled the wetland up and portions of it have been restored by the Johnsons (current homeowners). DISCUSSION The applicant is requesting a variance to permit the use of a 10-foot averaged buffer strip instead of the required 40-foot minimum buffer requirement to allow an addition of 11’ x 20’ sunroom on a lot zoned Single-Family Residential. The house was built in 1963 and predates the 1972 adoption of the zoning ordinance. The current home is within the 40-foot primary structure setback requirement from the required wetland buffer. The applicant has stated that enforcement of the buffer requirement would create practical difficulties and impose unnecessary burdens on them as it would prevent any additions to the south side of their home. The applicant feels that the presence of a preserve class wetland over the southern portion of the property and nonconforming location of the home create a practical difficulty which necessitates the requested variance. They have noted that a shed or other accessory structure of the same size and located in virtually the same spot as the project would comply with the City’s 20-foot accessory structure wetland buffer setback requirement for accessory structures (Section 20-411(b)) and could be built. The applicant believes that the size of the sunroom they are proposing is reasonable and notes that their home is significantly smaller than the neighboring houses. It has been the City’s general practice to require properties with existing nonconforming wetland setbacks to maintain those setbacks and not encroach further into the required wetland setback and the applicant’s proposed sunroom would be intensifying an existing nonconformity. This case is unique in that the Johnsons are proposing restoring a wetland that was removed by previous owners and to establish a buffer where no buffer is currently present. The applicant’s proposed wetland restoration and 10-foot averaged buffer will result in 5,218 square feet of restored wetland and 1,220 square feet of new buffer. Since the total of 6,438 square feet of restored wetland and established buffer are significantly more than the 4,732 square feet of buffer that would be required under ordinance, staff believes that granting the requested variance for a 10-foot averaged buffer will actually result in a superior result for the City. The requested variance will also result in the home no longer being a nonconforming structure, which will mean that future modest improvements would not require variances. For these reasons, staff supports the requested variance. 4 A full discussion can be found in the attached staff report. RECOMMENDATION Staff recommends that the Planning Commission approve the requested 10-foot averaged wetland buffer and adopt the attached findings of fact and decision, subject to the following conditions of approval: 1. The delineated wetland edge and required wetland buffer and structure setbacks shall be shown on the building permit survey. 2. A permanent 10-foot native vegetated buffer with permanent buffer signs must be installed as outlined in the variance exhibit submitted by the applicant. The buffer may be configured around the path and stairs. The buffer design and vegetation must be approved by the water resources engineer and installed in conjunction with the proposed home addition project. 3. A wetland buffer agreement describing the precise location and extent of the buffer strip, as well as the restrictions for activities within the buffer strip, shall be signed by the property owner and the City and shall be recorded against the property at the county recorder's office. The property owner shall be responsible for all costs and fees associated with the buffer strip dedication. 4. The installation of any improvements on the Site shall meet all applicable jurisdictional requirements, including but not limited to the Minnesota Department of Natural Resources and the Riley Purgatory Bluff Creek Watershed District, and all applicable permits shall be obtained prior to any site improvements. 5. The applicant shall obtain all required permits from review agencies with jurisdictional authority.

The home is a nonconforming structure as it is located within the 40-foot primary structure wetland buffer setback. Granting the requested variance would also remove the home’s nonconforming status and allow the addition of the sunroom.

The City has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi-judicial decision. Notice of this public hearing has been mailed to all property owners within 500 feet. PROPOSED MOTION: “The Chanhassen Planning Commission as the Board of Adjustment and Appeals approves a variance for a 10-foot averaged wetland buffer for the construction of an addition, subject to the conditions of approval, and adopts the findings of fact and decision.” 6 395 Red Cedar Point Road November 1, 2022 Page 2 of 7 PROPOSAL/SUMMARY The applicant is requesting a variance to permit the use of a 10-foot averaged buffer strip instead of the required 40-foot minimum buffer requirement to allow an addition of a 11’ x 20’ sunroom on a lot zoned Single-Family Residential.

Section 20-615, Lot Requirements and Setbacks. Chapter 20, Article II, Division 3. Variances Chapter 20, Article XII, “RSF” Single-Family Residential District BACKGROUND Country records indicate that the house was constructed in 1963. 7 395 Red Cedar Point Road November 1, 2022 Page 3 of 7 On June 11, 2001, the City vacated a portion of the roadway easement adjoining the property and designated the front lot line as the east property line, the rear lot line as the west property line and the north and south lot lines as side lot line. On July 3, 2001, the City issued a permit for a detached garage. On October 22, 2015, the City issued a demolition permit for a pool (pool appears on 1969 aerial photos and predates zoning code). Numerous other permits for interior maintenance and improvements are on file. The previous owners of the property filled the wetland up and portions of it have been restored by the Johnsons (current homeowners). SITE CONSTRAINTS Bluff Creek Corridor This is not encumbered by the Bluff Creek Overlay District. Bluff Protection There are no bluffs on the property. Floodplain Overlay Portions of the southern edges of the property are within the FEMA Flood Zone; however, no portion of the proposed project will take place within the area. Shoreland Management The property is located within a Shoreland Protection District and has Lake Frontage along the southern lot line. This district requires a 75-foot structure setback from the lake’s ordinary high- water level and limits the property to a maximum impervious surface coverage of 25 percent. It also requires 90 feet of lot width and a minimum 20,000 square feet of lot area. Wetland Protection There is a wetland on the property classified by the city as Preserve, which requires a 40-foot buffer and 40-foot wetland buffer setback. These are the highest value wetlands within the city and state area. They place a critical role in the protection of local water quality, wildlife habitat, and biodiversity. Even small impacts to Preserve Wetlands can have significant impacts to the health of our water resource communities. It is difficult to impossible to replace any lost function in Preserve Wetlands. 8 395 Red Cedar Point Road November 1, 2022 Page 4 of 7 The effectiveness of wetland buffers is directly connected to their width. The city buffer requirement for Preserve Wetlands is 40 feet. A reduced buffer could affect the function and health of this Preserve Wetland, and may have downstream impacts on Lotus Lake. The proposed development will not alter this wetland, but will rather restore some portion of lost wetlands; however, the wetland buffer requirements are not being met and a variance is required. Wetland Classification Principal Structure Setback from Buffer Edge (feet) Accessory Structure Setback from Buffer Edge (feet) Permanent Buffer Strip Minimum Width (feet) Percent of Buffer Strip in Native Vegetation Preserve 40 20 40 100% NEIGHBORHOOD The plat for this area was recorded in September of 1961. The immediate neighborhood is atypical in that access is provided to homes via a private drive partially overtop a communally owned outlot that was previously unutilized City right-of-way. Most of these homes in the immediate area are newer construction that meet the requirements of the City’s zoning code; however, the subject home is original to the development and nonconforming. The larger neighborhood is a mix of older and newer homes with most homes appearing to meet the requirements of the zoning code, though some structures are nonconforming.

When these properties with existing nonconforming wetland setbacks apply for variances to expand, staff has typically recommended that the expansion be required to maintain the existing wetland setback. In this case, the existing home does not meet the required 40-foot primary structure wetland buffer setback and is a nonconforming structure. The applicant is proposing to intensify this nonconformity by constructing a 11’x 20’ sunroom addition to their home. In order to do this, they are proposing restoring the wetland and creating a 10-foot averaged buffer. Granting this proposed variance would remove the property’s nonconforming status as both the exiting home and proposed addition would meet then the required 40-foot setback from the proposed wetland buffer. One of the findings necessary for granting a variance is that variances shall only be permitted when they are in harmony with the general purposes and intent of the Chapter and when the variances are consistent with the Comprehensive Plan. Chapter 20, Article 20-VI (Wetland Protection) under Sec 20-401(a) of the City’s Code which looks at findings; intent; rules adopted by reference states that “It is the intent of the city to promote the restoration of degraded wetlands”. The applicant has agreed to restore approximately 2,649 square feet of wetlands with native vegetation in addition the 2,569 square feet of native wetland vegetation that they have previously restored. They have agreed to maintain this area as vegetated wetland and the applicant has also agreed to install 1,220 square feet of wetland buffer. If the requested variance is approved, it will result to the restoration of approximately 5,218 square feet of wetlands and the addition of 1,220 square feet of wetland buffer. The applicant is doing this in exchange for a reduction of the required wetland buffer by approximately 3,152 square feet (i.e. the ratio of 10 395 Red Cedar Point Road November 1, 2022 Page 6 of 7 restored wetlands to decreased buffer is 1.65:1). From an ecological perspective, wetland restoration is often view more valuable than the buffer, which after all is only required to protect the wetland. It should also be noted that there is currently no buffer present on the property so the applicant’s proposed 10-foot averaged wetland buffer is an improvement to the existing conditions. Another findings necessary for granting a variance is when there are practical difficulties in complying with the zoning ordinance. The practical difficulty is created by the existing home’s location in relation to the wetland. As earlier mentioned, the building was built in 1963 and predates the 1972 adoption of the zoning ordinance. Granting the requested variance will remove the existing nonconformity by bringing the home into line with the required principal structure wetland setback, since the requested a 10-foot average wetland buffer will allow the house to meet the 40-foot building setback. It should be noted that the applicant can currently build a shed or other accessory structure of the same size, located in a similar spot to the project which will be in compliance with City’s 20-foot wetland buffer setback requirement for accessory structures. The proposed addition is reasonable as sunrooms are typical feature of homes and existing home is of relatively modest size with 2,208 square feet of living area. As point of comparison the surrounding homes are 4,402 square feet (675 Pleasant View Road), 3,842 square feet (665 Pleasant View Road), 3,350 square (745 Pleasant View Road), and 4,497 square feet (735 Pleasant View Road). Even after the proposed 220 square foot addition the home will be significantly smaller than the other homes in the neighborhood. Finally, another finding necessary for granting a variance is that the variance, if granted, will not alter the essential character of the locality. The project involves significant wetlands restoration, which will benefit Lotus Lake and the adjacent wetland area in a manner that advances the city’s comprehensive plan and wetland management policy, and enhances the natural character of the area. The addition of rear sunroom would not be expected to impact neighboring properties. Again, the applicant’s home is of modest in size and will remain so at completion of the project. There is no reason to believe that a small addition on the rear of the property would negatively impact surrounding properties. Given the modest nature of the proposed addition and proposed improvements to the property’s wetland, staff believes that approving the requested variance represents an appropriate balance between protecting the City’s water resources and allowing the applicant reasonable use of their property. For the reasons stated above, staff supports the proposed variance. RECOMMENDATION Staff recommends the Planning Commission, acting as the Board of Appeals and Adjustments, approve a ten-foot averaged wetland buffer for the construction of a sunroom and adopt the attached Findings of Facts and Decision, subject to the following conditions: 1. The delineated wetland edge and required wetland buffer and structure setbacks shall be shown on the building permit survey. 11 395 Red Cedar Point Road November 1, 2022 Page 7 of 7 2. A permanent 10-foot native vegetated buffer with permanent buffer signs must be installed as outlined in the variance exhibit submitted by the applicant. The buffer may be configured around the path and stairs. The buffer design and vegetation must be approved by the water resources engineer and installed in conjunction with the proposed home addition project. 3. A wetland buffer agreement describing the precise location and extent of the buffer strip, as well as the restrictions for activities within the buffer strip, shall be signed by the property owner and the city and shall be recorded against the property at the county recorder's office. The property owner shall be responsible for all costs and fees associated with the buffer strip dedication. 4. The installation of any improvements on the Site shall meet all applicable jurisdictional requirements, including but not limited to the Minnesota Department of Natural Resources and the Riley Purgatory Bluff Creek Watershed District, and all applicable permits shall be obtained prior to any site improvements. 5. The applicant shall obtain all required permits from review agencies with jurisdictional authority. ATTACHMENTS 1. Findings of Fact and Decision 2. Variance Document 3.

On November 1, 2022, the Chanhassen Planning Commission, acting as the Board of Appeals and Adjustments, met at its regularly scheduled meeting to consider the application. The Planning Commission conducted a public hearing on the proposed variance preceded by published and mailed notice. The Board of Appeals and Adjustments makes the following: FINDINGS OF FACT 1. The property is currently zoned Single Family Residential District (RSF). 2. The property is guided in the Chanhassen Comprehensive Plan for Residential Low Density. The legal description of the property is: Lot 5, Block 4, Red Cedar Point Lake Minnewashta 3. Variance Findings – Section 20-58 of the City Code provides the following criteria for the granting of a variance: a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the Comprehensive Plan. Finding:It is the intent of the City Code and Comprehensive plan to protect the City’s water resources. For this reason buffers and setbacks are required from wetlands. In this case, previous owners have filled and degraded significant portions of the property’s wetland and no buffer is currently present. The applicant is proposing to reestablish a significant portion amount wetland and install a buffer meeting the City’s minimum standards in order to offset the impacts of the requested wetland buffer variance. Additionally, the proposed increase in lot cover is would be permitted under the City Code in a location even closer to the wetland, were the applicant to create a free standing greenhouse rather than an attached sunroom. Given the above, the requested variance represents an improvement to the existing conditions and allows a level of impact the wetlands comparable or less than what applicant would be entitled to without a variance. For these reasons, granting the requested variance is in line with the intent of the zoning code and policies of the Comprehensive Plan. b.When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties" as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. 13 2 Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding:The buffer and setback requirements associated with a preserve class wetland prevent the applicant from constructing any additions to the southern portion of the home. These constraints prevent the property owners from adding typical improvements such as a deck or porch to their nonconforming home which is significantly smaller than the neighboring residences. c. That the purpose of the variation is not based upon economic considerations alone. Finding: The variance request is not solely based upon economic considerations. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding:The property was platted in 1961 and the home was built in 1963. Both the plat and home predate the City’s zoning ordinance and wetland protection standards. For this reason, the lot is configured in a way that would not permitted under the current zoning code and the home located in a place that would not be permitted by the current zoning code. The landowner’s plight is due to the nonconforming nature of the property and the preserve wetland located on the property. e. The variance, if granted, will not alter the essential character of the locality. Finding: The applicant has no rear neighbors and the location of the other surrounding homes means that their view should not be impacted by the proposed porch. Additionally, the additional will be over 200 feet from the lake’s ordinary high water level (OHWL) and would not be expected to impact the view or experience of recreationists utilizing the lake. Finally, the applicant’s home is significantly smaller than the surrounding structures and a modest increase to its footprint would not impact the character of the neighborhood. Regarding the environmental impacts, the wetland restoration and buffer that are part of the project will represent a net improvement to the area’s existing conditions. These features will help preserve the function of the preserve wetland bordering the lake, as well as the health of the lake itself. Restoring the wetland will help preserve the essential character of locality. f. Variances shall be granted for earth-sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. 4.The planning report #2022-15, dated November 1, 2022, prepared by Olivia Adomabea, et al. is incorporated herein. DECISION 14 3 The Planning Commission approves a variance for a 10-foot averaged wetland buffer for the construction of an addition, subject to the conditions of approval, subject to the Conditions of Approval. 1. The delineated wetland edge and required wetland buffer and structure setbacks shall be shown on the building permit survey. 2. A permanent 10-foot native vegetated buffer with permanent buffer signs must be installed as outlined in the variance exhibit submitted by the applicant. The buffer may be configured around the path and stairs. The buffer design and vegetation must be approved by the water resources engineer and installed in conjunction with the proposed home addition project. 3. A wetland buffer agreement describing the precise location and extent of the buffer strip, as well as the restrictions for activities within the buffer strip, shall be signed by the property owner and the city and shall be recorded against the property at the county recorder's office. The property owner shall be responsible for all costs and fees associated with the buffer strip dedication. 4. The installation of any improvements on the Site shall meet all applicable jurisdictional requirements, including but not limited to the Minnesota Department of Natural Resources and the Riley Purgatory Bluff Creek Watershed District, and all applicable permits shall be obtained prior to any site improvements. 5. The applicant shall obtain all required permits from review agencies with jurisdictional authority. ADOPTED by the Chanhassen Planning Commission this 1st day of November, 2022.

These comments are divided into two categories: general comments and proposed conditions. General comments are informational points to guide the applicant in the proper planning for this project, to inform the applicant of possible extraordinary issues and/or to provide the basis for findings. Proposed conditions are requirements that Water Resources recommends be formally imposed on the application in the final order. Note that references to the “City Standards” herein refer to the City of Chanhassen Standard Specifications and Detail Plates. General Comments/Findings 1. Any and all plans submitted with this application have been reviewed only for the purpose of determining the feasibility of the project and that the proposal is in accordance with City Codes and Standards. A recommendation of variance approval does not constitute final approval of plans and/or details. The applicant is required to submit detailed construction drawings for the project, as applicable. 2.The applicant is requesting a variance from the 40 feet buffer requirement defined in Chanhassen Code, Section 20-411 to facilitate the construction of a small addition to the home approximately 220 square feet in size. The setback variance for a wetland buffer with a preserve classification is 40 feet 3. The existing home extends into the wetland setback area by approximately 10 feet on the west side of the property. The proposed addition would extend the home footprint another 11 feet to the south resulting in a wetland setback of approximately 19 feet to the 40 foot 26 buffer. The project site is located on the north shoreline of Lotus Lake. The wetland on the property acts to filter and absorb nutrients and pollutants before they enter the Lake. 4. Shoreland wetlands are critical to the health of lake ecosystems and have numerous benefits including shoreline protection, habituate enhancement, water quality improvement, and flood abatement. 5. The home was constructed in 1963 before the City of Chanhassen adopted city ordinance to create permanent buffer strips with new developments starting in May 2007. The City of Chanhassen’s Local Surface Water Management Plan and City Ordinance outline the process to create permanent buffer strips for older, non-conforming lots. The City of Chanhassen’s Local Surface Water Management Plan Policy 2.14 reads: “Protect shorelands and water resources. All properties are required to have native vegetated buffer adjacent to wetlands, storm ponds, and water resources. Non- conforming properties, and lots of record shall be brought into compliance when applying for permits or variances to improve the property. Non-conforming buffers should attempt to meet regulatory requirements whenever possible. The minimum non- conforming buffer width shall be 10’.” City Ordinance - Shoreland Management District Section 20-490 of states: In evaluating all variances, zoning and building permit applications, or conditional use requests, the zoning authority shall require the property owner to address, when appropriate, stormwater runoff management, reducing impervious surfaces, increasing setback, restoration of wetlands, vegetative buffers, sewage treatment and water supply capabilities, and other conservation-designed actions. 6. A wetland delineation was completed by the applicant and approved on September 20 th, 2022. The Wetland Buffer and Wetland Enhancement Map exhibit created by the applicant shows the wetland location and the proposed buffer areas. 7. The buffer plan proposed by the applicant conforms with City Code for a non-conforming lot. The area of the proposed buffer is approximately 1,220 square feet and the parcel length is approximately 86 feet resulting in an averaged buffer strip of 14 feet. As part of the project the applicant has agreed to reestablish the wetland area which was previously managed as turfgrass by the previous owner. The applicant has already intentionally restored approximately 2,600 square feet of managed turf in the wetland to native vegetation. 27 8. City code outlines the wetland buffer agreement required for non-conforming lots. The buffer agreement describes the precise location and extent of the buffer strip, as well as the restrictions for activities within the buffer strip. The agreement shall be signed by the property owner and the city and shall be recorded against the property at the county recorder's office. 9. The water resources department supports the variance request. The proposed variance request would create a structure setback of approximately 59 feet from the wetland boundary, and about 56 feet from the edge of the buffer. The project would reestablish the wetland on the property and create/memorialize the adjacent buffer strips acting to improve and protect the downstream water resources. The impact of the small home addition would be offset by the wetland and buffer areas created. More information is needed to confirm the native vegetation types to be planted as part of the project. See condition 1. The buffer strip shall be memorialized with an agreement as outlined in City Code section 20-411. See condition 2. Lastly, any and all improvements on the Site must meet applicable jurisdictional requirements. See proposed condition 3. Proposed Conditions 1. A permanent 10 - foot native vegetated buffer with permanent buffer signs must be installed as outlined in the variance exhibit submitted by the applicant. The buffer may be configured around the path and stairs. The buffer design and vegetation must be approved by the water resources engineer and installed in conjunction with the proposed home addition project. 2. A wetland buffer agreement describing the precise location and extent of the buffer strip, as well as the restrictions for activities within the buffer strip, shall be signed by the property owner and the city and shall be recorded against the property at the county recorder's office. The property owner shall be responsible for all costs and fees associated with the buffer strip dedication. 3. The installation of any improvements on the Site shall meet all applicable jurisdictional requirements, including but not limited to the Minnesota Department of Natural Resources and the Riley Purgatory Bluff Creek Watershed District, and all applicable permits shall be obtained prior to any site improvements. 28 29 CITY OF CHANHASSEN STATE OF MINNESOTA) ) ss.

MEMBERS ABSENT: Ryan Soller. STAFF PRESENT: Kate Aanenson, Community Development Director; MacKenzie Young- Walters, Associate Planner. PUBLIC PRESENT: None. PUBLIC HEARINGS: 1. VARIANCE EXTENSION CODE AMENDMENT Community Development Director Aanenson gave a presentation on the item, noting the proposed change is to City Ordinance for an extension of variances. Currently variances expire after one year and there have been some circumstances with unusual constraints as to why it has not gone forward. The goal is to provide flexibility to accommodate extenuating circumstances, and it would also prevent the Planning Commission from re-hearing cases where the presumable result would be the same. Noyes clarified the extension still has to be requested by the applicant. Ms. Aanenson replied in the affirmative. Noyes noted the City has the ability to deny the extension if it is a frivolous reason of some sort. Ms. Aanenson replied in the affirmative. She noted the Applicant would request a timeline and the City would evaluate whether it is reasonable. They would not want to keep extending and extending. Chairman von Oven opened the public hearing. There were no public comments Chairman von Oven closed the public hearing. Commissioner Noyes moved, Commissioner Goff seconded that the Chanhassen Planning Commission recommends that the City Council adopt the proposed amendment to Chapter 36 Planning Commission Minutes – October 18, 2022 2 20 of the City Code concerning variance extensions. All voted in favor and the motion carried unanimously with a vote of 6 to 0.

The creek winds its way from a large wetland complex southeast of Lake Minne- washta through rolling hills and descends into bluffs dropping more than 70 feet into the lower valley before discharging into Rice Lake and the Minnesota River. The Bluff Creek Watershed is approximately 9.6 square miles and runs north to south along the western portion of the City of Chanhassen. The watershed is in a state of land use transition due to the community's rapid growth and development. Bluff Creek itself will likely experience Increasing volumes of runoff associated with new development in the coming years. In its comprehensive plan, the City of Chanhassen has identified the Bluff Creek area as an environmental and recreational resource. In order to preserve the area, it is the City's goal to acquire lands adjacent to the stream as opportunities arise and funding permits. The City has already acquired portions of the corridor through easement and fee title as development has occurred.

Serious efforts began in 1993 to produce a watershed plan that would look at the system as a whole, rather than individual parts. The City's Stormwater Management Plan was a first attempt to protect the natural conditions of the creek. The Plan provides recommendations for the protection and preservation of Chanhassen's surface water features. The City is taking a bold step to identify its vision not for the next few years but for generations to come. In 1994, the City identified a need for a process to prepare and implement this Natural Resources Plan for Bluff Creek, which would include a partnership among community, state, county and federal agencies; nonprofit organizations, and the private sector (businesses and developers). In 1995, Steering and Technical Committees were formed. Steering Committee members were recruited through the Chanhassen Villager, Chanhassen newsletter and by word of mouth. It was the City's goal to gather- a diverse group to serve as the "debate and compromise center" on various issues. Steering Comrnittee members included: Citizens Landowners in the watershed Representatives from the development community A Planning Commission member A City Council menlber A park and recreation committee member A repr-esentative from the business sector A representative from a nonprofit organization The Technical Committee was a compilation of experts in several natural resource fields from several agencies, City Staff and the consulting firm of Bonestroo, Rosene, Anderlik & ASSOCiates. They were kept informed on issues and were called on an as-needed basis. The City received letters of suppol1 to pursue a gr-ant from the Legislative Commission for Minnesota Resources (LCMR). Suppol1ers included: Boar-d of Water' and Soil Resour-ces Minnesota Landscape Arbor-etum I I Gluff CV'f'elii WClteV'5~ed ~~CltllV'Cl1 Re5wV'ce5 MClVlClgeWleVlt PIClVl Page 2 42 I I I I I I I I I I I I I I I I I I I Metropolitan Council Minnesota Valley National Wildlife Refuge University of Minnesota Department of Landscape Architecture Riley Purgatory Bluff Creek Watershed District Carver County Minnesota Department of Natural Resources Heritage Development Builders Association of Minnesota Citizens State legislator's serving on the LCMR 1995 Initiative toured the Bluff Creek Watershed area; however, LCMR funding was not approved. The Bluff Creek Watershed Plan did received funding from the City of Chanhassen, the Minnesota Department of Natural Resources and the Riley Purgatory Bluff Creek Watershed District in 1995. In addition, the Metropolitan Council Water Quality Initiative has granted the City seed funds to begin project implementation as designated by this plan. The City is already pursuing other potential sources to fill the implementation coffers. Those sources include: The City of Chanhassen The Riley Purgatory Bluff Creek Watershed District The U.S. Fish and Wildlife Service The McKnight Foundation The City anticipates using the Plan as a tool for seeking further funding. This plan presents the Steering Committee's vision and the means to accomplish it through project implementation, education and financial suppoli. Hopefully, 40 to 50 yeat-s from now, the citizens of Chanhassen and the metropolitan area will look at Bluff Creek and the surrounding environmental and recreational amenities and be grateful for- those who had the foresight to protect and preserve this area. I.B (OVlSE'vlSL15 BV1ilc1ivlg A Steering Committee was formed to reach a shared understanding on the vat-ious issues at stake. The Committee was well represented by City residents, land owners in the water-shed, developers, a business sector representative, a planning commission member, a city council membe,', a par-l< and recreation committee member, and a non-profit organization representative. r3lllff CreeR WCltersf1ed NCltl1V'Cl1 Resol1rces MClVlClgeVVlE'f1t PICll1 L-: \,~,-..J I~IJ Page 3 43 I I I I I I I I I I I I I I I I I The Steering Committee's participation in the development of the Bluff Creek Watershed Natural Resources Management Plan involved two phases. In the first phase, participants were informed and educated on the natural history of the watershed, from pre-settlement times to the present day, along with human impacts and current demographic. The second phase was intended to help participants develop a collective vision and goals for the watershed its natural and artificially created features and functions as they would like it to appear 40 to 50 years from now. To gain a first -hand perspective of the current topography, vegetation, wildlife habitat and land uses within the watershed and the surrounding areas, the Committee toured selected sites along Bluff Creek. Committee meetings were held in October, November and December of 1995. At these three meetings, state agency staff and city staff presented historical and contemporary data about: Bluff Creek and its biology, geology, hydrology, and wildlife Local and metropolitan settlement patterns and projections Historical. current and proposed land uses within the watershed and adjacent areas L> The impact of land uses on the natural environment Potential educational and interpretive uses of the Creek At the Decernber meeting, Steering Committee members were asked to start creating a personal vision of the watershed 40 to 50 years from now by imagining "the worst and best outcomes" for the Bluff Creek natural resources management efforts. In January 1996, the Steering Committee began the process of formulating a vi~ion and setting goals for the watershed. At that meeting, attendees were divided into three random groups. Concurrently, pal1iclpants at each table addressed the question: "What ar-e the wor'st possible outconies that could occur in the Bluff Creek Watershed 4050 years from now as the result of ~he Bluff Creek Natul'al Resources Management Plan that we are helping to create?" (See Appendix C for complete list) They then repeated the processes, asking themselves for the "best pOSSible outcomes." Following the January meeting, city and consultant staff then used all of the best outcomes" to create the first draft of the Steering Committee's collective vision.

Changes were made through group consensus. On a parallel track, the Technical Committee began its review of the vision and goals to determine the implications of their implementation. The Committee examine9 such areas as technical feasibility, long-term management requirements, property ownership and acquisition, zoning, and funding. The Committee's analysis led to specific site and content recommendations that would fulfill the goals yet be consistent with natural characteristics and artificially created constraints. Committee members also delineated a set of primary and secondary boundaries for the al-ea affected by the vision, revealing the total land mass to be taken into consideration. The findings of the Technical Committee, presented at the Mar-ch and April Steering Committee meetings, are identified in Section 4: Implications of the Vision. The implications of implementing the vision were analyzed and discussed. Then the participants were allowed to add substantively to the vision (and consequently the goals) through the first draft of the collective statelTlent until consensus was reached.

For our mutual health and well-being, we depend on the fresh water, clean air and fertile soil of our native landscape. We exist within a regional ecosystem that, in turn, is part of the global web of life. What we do with our part affects the whole, and how we care for each other will shape our future. We have the duty to nurture nature by preserving its special beauty, protecting its species diversity and respecting our shared habitat. In Chanhassen, at the edge between the Great Prairie Region and the Big Woods Region, we enjoy the benefits of both a dynamic metropolis and a flourishing countryside. Here, the Bluff Creek Watershed offers the opportunity to exercise the highest qualities of civic responsibility and environmental stewardship. As a natural resource, this waterway presents rare aesthetic and recreational possibilities. As a wild sanctuary, the valley cut by Bluff Creek provides a vital wildlife habitat and refuge from surrounding urbanization. As a part of a regional ecosystem, it exists as an essential link to recreational parkways and wildlife preserves encompas- sing the area from lakes Minnetonka and White Bear to the valleys of the St. Croix, Mississippi and Minnesota Rivers. We envision our work as a process where citizen education and involvement are essential to foster sustainable communities in balance with nature. r: r'-)~:~~: t:r~ .............: . ~_'. ....

The best possible outcome of Chanhassen's management efforts for the Bluff Creek Watershed would be that... Bluff Creek is a model - the focus of identity and pride to the people of Chanhassen, a community that is integrated with and celebrates its natural environment. An achievable natural resources management plan has been Page 6 46 I I I I I I I I I I I I I I I I I developed. Its goals have met the needs of both natural systems and people through integration of Chanhassen's more populated areas while maintaining Bluff Creek's natural condition. Watelshed management is shaled by various government agencies. private groups and IIItelested parties While governmental agencies embrace the plan. no government intervention is required to accomplish its goals. The citizens care about natural areas and take an active role in management and protection. Residents of all ages have volunteered to maintain the pristineness of the watershed.

Property available for development within the existing Metropolitan Urban Service Area (MUSA) is not taken through zoning. Property outside the MUSA can be acquired without condemnation proceedings. Chanhassen would try to flcquire at least an edge of property on the east bluff. Significant portions of property within the eXisting MUSA that the plan intends to incorporate will be acquired. Tax incentives are given to landowners for using their land for conservation purposes. Ideally, no more people would move into the area.

TherE: IS ecosensitivernixed development (farms, housing, industry) with buffer al'eas between development and wild areas. Development within the watershed has been clustered to create more open space. There IS open countryside between clustered nodes of development and several large pieces of open land and woodland along the creek. Tributaries have been preserved for recreation and to ensure sufficient habitat area for wildlife. Thele are a vallety ofpreserved habrtats and enV/fonments (r. e. wetland woodland. prall/e. ete). The natural areas have been stabilized by native vegetation (i.e big woods. tall grass prairie. wetlands).

The design of an open space network has protected diverse wildlife habitats and cultural landscapes, such as farmland. In addition, there is adequate access to trails, parking. facilities and interpretive elements. There are numerous active areas for picnics to minimize pressure on native wild areas. The upper Cleek is accessIble for a valiety of uses including a trail system on the upper and mIddle reaches. wtth possIble out-of-comdor connections to observation areas A multiple use trail runs nor1h from Pioneer Trail for biking, running and skiing. Side trails connect with neighborhoods. A community park in the upper reaches is contiguous to the trail system.

Stgmficant envlionmental areas thlOugh the comdor Will be IdentIfied and priorttized with a rating system The spectacular lower creek has been preserved in Its natural state with a rustic, limited-use nature trail running its length. Upstream development is limited to preserve the lower ueek. Areas once degr-aded have been restored and maximum protection against pollution caused by urbanization has been achieved. The restoration goals for the watershed are realistic. In the lower creek, preservation of woods, stream quality, wetlands, wildlife and a nature sanctuary lets the sounds of nature, not cars, be heal-d. Habitats fOI the watersheds native aminals and plants WIll be defined accoldli7g to thell" needs The former fields and drained wetlancJs of the upper creek have been restored to the original big woods region vegetation. All vegetation within 300 feet of the creek al-e preserved. Invasive non-native species sllch as purple loosestrife and buckthorn are eliminated. The creek supports fish and serves as a wildlife corridor supporting deer, fox, turkeys, beaver and coyote. The wildlife is thr-Ivlng and circulating freely throughout the greenway. Water quality IS h(i;h tl7loughout the watershed The water quality IS maintained and protected through recharge, infiltration, grassed waterways and restored wetlands that absorb stormwater runoff. If needed, open water storage areas either in-stream or upland are developed and natural flood control is achieved through these restored wetlands as reservoirs in the upper valley.

Gully erosion in the lower creek has been stopped by natural means (i.e. runoff control and revegetation). It is a stable system requiring minimum maintenance and expense. Bluff Creek and its tributaries are restored to their natural water courses and are lined by natural wetland vegetation. Creek highway crossings allow for a pleasing vista by passing motorists, but ensure the continuity and natural integrity of the creek corridor. To be effective, wlld/;(e corridors and green ways will be connected to larger preserves such as farmland and woodlands; therefore, comprehensive planning goes beyond (the) creek corridor to connect other natural areas. Bluff Creek is a link in a metropolitan chain of recreational and wildlife habitat open spaces. All children at Bluff O-eek ElementalY School are involved in watershed awareness, The creek serves as a field laboratory for the schools, teachers, and community. There is an interpretive nature center in the upper creek near the school easily accessible to high volume activity. A multi-level observation/education facility includes one short trail loop to the creek and back in the lower reach. The Minnesota River bluffs are used as a scenic overlook and as an educational resource. There is an interpretive nature trail from the southwest regional Light Rail Transit to Pioneer Trail or Lyman (walk-in only). 11.13 Coals The following goals for the Bluff Creek Watershed were Identified in the Collective Vision Statement of the Steering Committee.

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 surface water management plan. (b)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 Regional 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 nonmotorized transportation. (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 Natural Resources Management Plan. The terms, definitions and appendices found in the management plan are incorporated herein. 52 (Ord. No. 286, § 8, 12-14-98; Ord. No. 445, § 6, 2-12-07) Sec 20-1552 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 district; 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 surface water management plan. (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 manmade 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. (Ord. No. 286, § 8, 12-14-98; Ord. No. 445, § 7, 2-12-07) Sec 20-1553 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 attached to 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. (Ord. No. 286, § 8, 12-14-98) Sec 20-1554 Conditional Use Permits (a)A conditional use permit shall be issued by the city for all subdivisions, site plans, and prior the erection or alteration of any building or land within the BCO. (b)All lots of record in existence and parcels of land located within the Bluff Creek Overlay District on which a principal structure has been constructed prior to December 14, 1998, are exempt from requiring a conditional use permit. Further subdivision of the property will require a conditional use permit and shall comply with the Bluff Creek Overlay District. (Ord. No. 286, § 8, 12-14-98; Ord. No. 364, § 1, 1-12-04) Sec 20-1555 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 53 regulations. The Bluff Creek Overlay District regulations shall not be construed to allow anything otherwise prohibited in the zoning district where the overlay district applies. (b)Boundaries; maps. The primary and secondary zones include land that is generally defined in this ordinance 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 community development 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 community development director's determination of the watershed zone boundary and type to the city council. (Ord. No. 286, § 8, 12-14-98; Ord. No. 377, § 155, 5-24-04) Sec 20-1556 Impervious Surface, Lot Coverage And Slopes (a)To the greatest extent possible, all development shall minimize the amount of lot coverage 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 runoff caused by impervious surfaces shall be designed using practices delineated in the city's surface water management plan. (b)Within the secondary zone of the BCO district, areas with average slopes exceeding 25 percent shall be preserved in their natural state and maintained as permanent open space. Areas with average slopes less than 25 percent but greater than ten percent shall not exceed 25 percent lot coverage. Lot coverage for areas where average slopes are less than ten percent shall be governed by the underlying zoning district. (Ord. No. 286, § 8, 12-14-98; Ord. No. 445, § 8, 2-12-07; Ord. No. 628, § 51, 12-11-17) Sec 20-1557 Bluffs Bluffs shall be preserved as provided for under article XXVIII. (Ord. No. 286, § 8, 12-14-98) Sec 20-1558 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 BCO 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.

No. 377, § 156, 5-24-04) Sec 20-1559 Density Clustering Density clustering shall be allowed as a tool to facilitate cluster development within the Bluff Creek Overlay District. Density clustering may be used in areas where portions of the site are unsuitable for development because of the location of the primary zone. 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 zone, subject to the restrictions of this ordinance, and within land lying outside of identified zone areas. Additionally, the following conditions may qualify for density clustering: (a)Land slopes in the secondary zone that exceed 25 percent on average. (b)Land in the secondary zone containing stands of native trees. (c)Land with suitable natural habitat to endangered or threatened species or a fragile ecosystem. Traditional Development Pattern 55 Cluster Development Industrial Cluster Development 56 (Ord. No. 286, § 8, 12-14-98; Ord.

(Ord. No. 286, § 8, 12-14-98) Sec 20-1561 Natural Habitat Preservation (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 development of a 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 surface water management plan. (Ord. No. 286, § 8, 12-14-98; Ord. No. 377, § 158, 5-24-04; Ord. No. 445, § 9, 2-12-07) Sec 20-1562 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. 57 (Ord. No. 286, § 8, 12-14-98) Sec 20-1563 Open Space Requirements Open space shall comprise 100 percent of the area located within the primary zone. The city will establish the boundary for the primary zone using data provided by the applicant. (Ord. No. 286, § 8, 12-14-98) Sec 20-1564 Structure Setbacks (a)All structures shall be set back a minimum of 40 feet from the primary zone, except as specified below. No disturbances of the site shall occur within the first 20 feet of such setback from the primary zone boundary. (b)On parcels of land located within the Bluff Creek Overlay District on which a principal structure has been constructed prior to December 14, 1998: (1)The minimum setback from the primary zone shall be the existing principal structure setback, if less than 40 feet. (2)If the existing principal building or structure setback is less than 40 feet and greater than or equal to 20 feet, then the first 50 percent of the established primary zone setback shall remain undisturbed. (3)If the existing principal building or structure setback is less than 20 feet there shall be no grading or alterations beyond the existing setback. (Ord. No. 286, § 8, 12-14-98; Ord.
