I did not mean to imply these were oaks and will take forever to grow. I am disappointed to see the proposed plan destroying the larger trees and adding no large buffer between the street and the building or parkland. Most importantly, the builder's plan to use 1% of a budget for a majority of formal which is simply not the same as the existing habitat and in my eyes are not seen as a balance or equal trade for the existing. Thank you for your email.

Thank you for sharing your concerns about the landscaping. It's true that the placement of the building and parking lot will require all of the trees on the south half of the property to be removed. These trees include ash, boxelder, elm, cottonwood, and honeylocust which seeded into the area from neighboring trees. These species are fast growers and have put on some girth, but the majority of these existing trees are young. The evergreens are part of the old homestead landscaping from the original home. The replacement overstory trees, oak, birch, elm and honeylocust, will have wildlife and pollinator habitat benefits but will be in a more formal landscape. The trees will be a positive for the site as they are longer lived, provide the essential environmental benefits, won't succumb to known, fatal insect and disease issues such as emerald ash borer and Dutch elm disease, and will receive ongoing maintenance to ensure their health and longevity. The north half of the property which contains more ash, elm, boxelder, cottonwood plus other native species, such as maple, will be protected and preserved and provide a valuable extension of the natural areas encompassed by Lake Ann park. If you have any further questions or concerns, please contact me.

I have reviewed some of the documentation submitted for this site and my primary concern for this site is the location's existing mature trees. The proposal to spend 1%of the project budget on new landscape, which focuses heavily on ornamental, shrubs, perennials and other vegetation that does not compare in the replacement of the large mature trees which exist there today. It appears the orientation of the building will allow for some existing trees to be left nearing the wetland area, but many others will be destroyed. There must be a better way to save more of the existing trees, perhaps changing the orientation of the building or shrinking it, to limit the removal of the larger, mature trees which protect wildlife and cannot be replaced for years to come. Putting a smaller, Rural Residential home(s) here would not have the environmental impact, including the loss of a grove of trees and natural setting which wildlife, birds and people in the are of Lake Ann all enjoy. Should the city determine this project will in fact move forward with rezoning, I hope you will help by reviewing the need for a larger focus on the landscape. So often landscape details meet simply the minimum request and get approved.

CivilSite G R O U P Memorandum TO: Sharmeen AI-Jaff Senior Planner City of Chanhassen FROM: Patrick Sarver, PLA. Civil Site Group DATE: 01 /28/2020 RE: Moments of Chanhassen, Chanhassen, MN We are requesting Municipal approvals to construct the Moments of Chanhassen. This one-story, 48 unit, 65,000 GSF building, includes a lower level resident amenity space, look -out units, storage and underground parking. Due to the existing site conditions & constraints, including dynamic topography, wetland location, and adjacent street frontage treatments, a traditional parking and building location, orientation, and setbacks have proven excessively difficult to achieve without drastically degrading the services and amenities required for this type of site use. Therefore, we are requesting flexibility in both the parking setback requirement and a reduction in setback along the smaller wooded wetland, through the use of wetland averaging. Given the unique shape and location of the wetland we are proposing significant increase in setback from the wetlands and natural features on both the eastern and western ends of the site to counterbalance the reduction in setbacks at the center of the site. We are proposing to replace the existing vegetation that is disturbed by our construction activities with a low/no maintenance area along the entire north side of our site, with the ultimate goal being an overall enhancement and expansion of the buffer from the highest quality natural wetland features. It is the intention of the developer/owner and the development team to earnestly engage with the stakeholders for this site, including City Staff, Riley Purgatory Watershed Staff, and our immediate Lake Ann community, to enhance, protect, and highlight the phenomenal natural resource that will become our future Moment's of Chanhassen home. To help to mitigate the impacts of these setback modification requests, we are proposing significant enhancements to the building architecture, landscape improvements and screening. We are proposing enhanced screening along the south side of the parking lot and building foundation, as well as minimizing grading along the north side of the building so as to retain as much naturally occurring native plant material as possible. We also are proposing to reintroduce native/LID (Low Impact Design) plant material, and native plant restoration to further improve the stormwater runoff into the adjacent wetland areas. We also plan to remove the invasive impacts from the Buckthorn species that has likely negatively impacted the viability of the natural vegetation throughout the site. The Owners/Operators of the Moments of Chanhassen are proud be providing high quality senior care in their currently operating facility in Lakeville but are equally excited to start construction of their second home on this premier Chanhassen location in 2020. Thanks for your consideration and attention on this matter.

PROPOSAL/SUMMARY The request consists of multiple applications to facilitate the construction of a continuing care retirement facility (The moments of Chanhassen). The request includes a Rezoning from Rural Residential District to High Density Residential District, site plan approval with variances for the construction of a continuing care retirement facility. The site is located north of West 78th Street and west of Lake Ann Park. Access to the site will be gained off of West 780' Street. The site is zoned Rural Residential District. Planning Commission The Moments of Chanhassen February 4, 2020 Page 3 of 19 The following is a summary of the requests: 1. Rezoning: The first request is to rezone the property from Rural Residential District to High Density Residential District. This request is consistent with the Land Use Plan. 2. Site Plan: The request is for a site plan to construct a 65,000 square -foot continuing care retirement facility. The total permitted site coverage is 50 percent. The proposed development has a total hard coverage area of 34.5%. The design of the building is attractive and is proposed to be constructed of high -quality materials. They include Limestone at the entry and the main body of the building. E1FS is used as an accent material. All elevations that can be viewed by the public have received equal attention. Parking is buffered from views by landscaping. Access to the site is provided via West 78 h Street. The site contains multiple wetlands, a creek and is within the shoreland overlay district. 3. Variance: The applicant is requesting a Zero wetland setback variance and a Front Yard setback variance. Staff is recommending a minimum of 5 foot wetland setback and approval of the front yard setback variance. 4. Lot Consolidation: The site is comprised of two parcels. Staff is recommending the parcels be consolidated into a single zoning lot. This will be a condition of approval of the site Plan. Staff regards the project as a well -designed development. The overall design is sensitive to the surrounding area. Based upon the foregoing, staff is recommending approval of the rezoning, site plan and variances with conditions as outlined in the staff report. Planning Commission The Moments of Chanhassen February 4, 2020 Page 4 of 19 The site was formerly occupied by Natural Green, a Landscape Contractor Business. In 1989, the business moved and the site was restored. The Land Use Plan designates the site as Residential High Density (Net density 8-16 Units/Acre). These categories have been established to accommodate either high -density residential development. A Continuing Care Retirement Facility is a permitted use in a High Density Residential District. The applicant is proposing to rezone the property from Rural Residential to High Density Residential District. The area to the north and west contains a single family home and is guided Residential High Density. Lake Ann Park is located east of the subject site and is guided Parks and Open Space. West 78a' Street is located south of the subject site.

Appropriate zoning for this land use is R-12, R-16, RLM, or PUD-R. The use consists of a single building with 48 individual rooms. The occupants of the building will be individuals that need assistance with their mobility and will not put the same level of demand on the infrastructure that a typical high density development would This area is in the Metropolitan Urban Service Area (MUSA). Staff is recommending that this area be rezoned to R-16 and finds that the rezoning is consistent with the Comprehensive Plan. SITE PLAN This building must comply with the Design Standards for the multi -family district and the standards set in the continuing care retirement facility. The city code requires the development to have an attractive design and use durable materials. Site coverage may not exceed 50 percent. The total hard surface coverage proposed on the site is 34.5%. The design of the building is attractive and is proposed to be constructed of high -quality materials. They include Limestone for the main body of the building and EIFS (exterior insulation and finish system) as an accent material. All elevations have received equal attention. Parking is buffered from views by landscaping. The majority of the parking is underground. The trash enclosure for the building is located inside the building. The added landscaping will provide a calming effect to a busy area. The site plan request is for a 65,000 square - foot continuing care retirement facility. The building has a pronounced entrance, utilizes durable exterior materials, and exhibits articulation. Planning Commission The Moments of Chanhassen February 4, 2020 Page 6 of 19 The north elevation contains a patio area. The roofline is staggered, well -articulated and enhances the design of the building. The applicant is requesting two variances pertaining to setbacks. The first variance is a parking setback variance. The City Code requires a 25 foot setback. The applicant is requesting to reduce the setback to 10 feet. The parking is adequately screened from views off of W. 78'h street and staff is recommending approval of the parking setback variance. The applicant is also requesting a zero foot wetland setback variance. In return, the applicant is providing a wider buffer in other areas around the wetlands. Staff is recommending the applicant maintain a minimum of 5 foot setback from the edge of the butter \ Riley Creek rr �� d _ .I �9 1 Planning Commission The Moments of Chanhassen February 4, 2020 Page 7 of 19 Sec. 20-965. - Continuing care retirement facility.

Planning Commission The Moments of Chanhassen February 4, 2020 Page 8 of 19 PARKING The ordinance requires one-third parking space per bed with an additional parking space for every employee on the largest single shift. The building has a capacity for 48 individuals which translates to 16 parking spaces. The major shift will have 25 employees. The total number of parking spaces required is 41. The applicant is providing 44 parking spaces. ARCHITECTURAL COMPLIANCE Size, Portion and Placement Entries: The building has a pronounced entrance. Articulation: The building incorporates adequate detail and has been tastefully designed. The architectural style is unique to the buildings but will fit in with the surrounding area. The building will provide a variation in style through the use of Limestone and EIFS. The building utilizes exterior materials that are durable and of high quality. Signs: All signage must meet the sign ordinance. Material and Detail High quality materials are being used on the building. Color The colors chosen for the building are earth tones. The selection is unique, but blends in with the surrounding buildings. Height and Roof Design The maximum building height permitted is three stories. The building meets the ordinance requirement. The roofline is staggered, adding articulation to the design of the buildings. The ordinance requires a pitched element on building. Multiple dormers are used to break the expanse of the pitched roof to comply with this requirement. All rooftop equipment must be screened from views. Facade Transparency All facades viewed by the public contain more than 50 percent windows and/or doors. Loadina Areas, Refuse Areas, etc. Planning Commission The Moments of Chanhassen February 4, 2020 Page 9 of 19 The trash enclosure is located inside the building. Recycling space and other solid waste collection space should be contained within the same enclosure. SITE PLAN FINDINGS In evaluating a site plan and building plan, the City shall consider the development's compliance with the following: (1) Consistency with the elements and objectives of the city's development guides, including the comprehensive plan, official road mapping, and other plans that may be adopted; (2) Consistency with this division; (3) Preservation of the site in its natural state to the extent practicable by minimizing tree and soil removal and designing grade changes to be in keeping with the general appearance of the neighboring developed or developing areas; (4) Creation of a harmonious relationship of building and open space with natural site features and with existing and future buildings having a visual relationship to the development; (5) Creation of functional and harmonious design for structures and site features, with special attention to the following: a. An internal sense of order for the buildings and use on the site and provision of a desirable environment for occupants, visitors and general community; b. The amount and location of open space and landscaping; c. Materials, textures, colors and details of construction as an expression of the design concept and the compatibility of the same with adjacent and neighboring structures and uses; and d. Vehicular and pedestrian circulation, including walkways, interior drives and parking in terms of location and number of access points to the public streets, width of interior drives and access points, general interior circulation, separation of pedestrian and vehicular traffic and arrangement and amount of parking. (6) Protection of adjacent and neighboring properties through reasonable provision for surface water drainage, sound and sight buffers, preservation of views, light and air and those aspects of design not adequately covered by other regulations which may have substantial effects on neighboring land uses. FindinE: The proposed development is consistent with the City's design requirements, the comprehensive plan, the zoning ordinance if the setback variances are approved, the design standards, and the site plan review requirements. Staff is recommending approval of the request Planning Commission The Moments of Chanhassen February 4, 2020 Page 10 of 19 with conditions. The site design is compatible with the surrounding developments. It is functional and harmonious with the area. Staff regards the project as a reasonable use of the land. The overall design is sensitive to the City's image. Based upon the foregoing, staff is recommending approval of the site plan with conditions outlined in the staff report. ACCESS The development fronts on W 78s' Street near the intersection of Audubon Road and TH 5 and proposes one access driveway on the far west side of the site. The Minnesota Department of Transportation (MnDOT) was provided plans for review due to the proximity of TH 5 and had no comments or subsequent conditions based on the provided plans. Twenty-three parking stalls are distributed near the west side of the building and an additional seventeen parking stalls are located underground. A turn -around, as required by Sec. 20-1122.41 due to access being had from a collector street, has been integrated near the parking stalls to the west of the building. A turning movement analysis utilizing the largest anticipated design vehicle (at a minimum the largest Chanhassen Fire Department truck) shall be provided to ensure there is adequate spacing with no conflicts within the turnaround, the driveway entrance/exit, and with the traffic control devices located on W 781 Street (raised median, pavement striping, etc.). EASEMENTS The existing condition survey, which was completed in accordance with the 2016 Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys, did not find any existing easements on the subject properties. However, the provided existing condition survey did not survey the entire limits of proposed construction. The applicant is proposing construction south of the property within right-of-way (City and MnDOT) for sanitary sewer service, discussed later in this report under "Utilities". The applicant will be required to update the existing condition survey to incorporate the full extent of the proposed construction limits. GRADING The applicant is proposing to grade the site to accommodate the construction of a 48 unit (65,000 gross square feet) senior care building, which includes underground parking. Through the proposed grading plan, drainage will be routed away from the building into a series of catch basins and stormwater pipe located in the drive and parking areas, and then directed to a filtration basin on the eastern portion of the development. Due to the constraints of the site, the applicant is proposing to grade within a wetland buffer. The accompanying landscaping plan does not indicate any restoration of the disturbed area. Per City Code, restoration with native plant species is required for any disturbed areas within a wetland buffer during construction. This needs to be revised on the plans along with the location of the required wetland buffer monumentation. Furthermore, the grading plan must indicate the location of stockpiles and provide haul routes for any required fill/excavation. WETLANDS Planning Commission The Moments of Chanhassen February 4, 2020 Page 11 of 19 A Notice of Decision of the wetland boundary and type was approved on 7/19/2019. The wetland delineation indicates the wetland is 0.0073 acres of a Type 1/2, located adjacent to Riley Creek. While there is no direct impact to the wetlands on -site, the applicant is proposing to encroach into the proposed wetland buffer during construction activities, as discussed previously under "Grading". Additionally, the applicant is requesting wetland buffer averaging and a reduction in wetland buffer setbacks due to site conditions and constraints, such as: dynamic topography, wetland location in relation to site boundaries, and adjacent street frontage treatments. While staff generally agrees that the site has inherent constraints due to the location of the wetland and the proposed structure and property lines, the applicant's proposal is to have a minimum buffering average width of twenty 20 feet coupled with a zero foot setback at one location and less than five feet at another, as illustrated below. While staff believes a 20 foot minimum buffer with averaging is acceptable, the approval of the buffering average must also be reviewed and approved by Riley Purgatory Bluff Creek Watershed District (RPBCWD). The setback is solely regulated by the City and City Code under Sec. 20-411. The minimum setback requirement for a principal structure from the buffer edge is 30 feet for wetlands classified as Manage 1/2. This setback is necessary to maintain an area to allow property/building owners to maintain the primary structure and its surroundings while not encroaching nor disturbing the wetland buffer. A zero foot setback would not allow for such maintenance, promoting encroachment into the buffer, and should not be approved. Due to the constraints of the site, staff recommends a minimum of a five foot setback be adhered to at all times along the wetland buffer, and plans be resubmitted illustrating conformance with this condition for review and approval by the City prior to recording of the Site Plan Agreement. RETAINING WALLS Planning Commission The Moments of Chanhassen February 4, 2020 Page 12 of 19 A total of five retaining walls are proposed with the development. One retaining wall, extending from the northwest corner of the building, appears to be over four feet in height. While top -of - wall and bottom -of -wall elevations were not provided, based on proposed topographic grade line elevations it appears the retaining wall will reach a maximum height of approximately nine feet. Bottom wall elevations and top of wall elevations for the entire wall section for all five retaining walls shall be provided. In accordance with Sec. 20-1025 of City Code, walls that exceed four feet in height shall be designed by a registered engineer, and plans shall be submitted for review and approval prior to the commencement of any grading activities. DRAINAGE AND EROSION CONTROL The proposed development will exceed one acre of disturbance and will, therefore, be subject to the General Permit Authorization to Discharge Stormwater Associated with Construction Activity Under the National Pollution Discharge Elimination/State Disposal System (NPDES Construction Permit). All erosion control shall be installed and inspected prior to initiation of site grading activities. The applicant has submitted an erosion control plan and a Storm Water Pollution Prevention Plan (SWPPP), however revisions and updates to the plans and SWPPP are required in order to meet the requirements of the NPDES Construction Permit and Sec. 19-145 of City Code. This will include, but is not limited to: updated language in the SWPPP to be site specific and not general language pulled directly from the permit; BMPs to protect planned infiltration/filtration areas; provide redundant (double) perimeter sediment controls when a surface water is located within 50 feet of the project's earth disturbances; location of stock pile for grading and for topsoil. A more detailed redline of the SWPPP and erosion control plan will be provided to the applicant. STORM WATER MANAGEMENT Article VII, Chapter 19 of City Code describes the required storm water management development standards. Section 19-141 states that "these development standards shall be reflected in plans prepared by developers and/or project proposers in the design and layout of site plans, subdivisions and water management features." These standards include abstraction of 1.0 inch of runoff from the new impervious surfaces created by the project and water quality treatment resulting in the removal of 90% total suspended solids (TSS) and 60% total phosphorous (TP). The applicant has provided a stormwater management proposal that meets the standards set forth in Chapter 19 for TSS and TP removals, but not abstraction. The applicant has submitted a preliminary Stormwater Management Report (SMR) produced by Matthew R. Pavek, P.E. (MN No. 44263) with Civil Site Group. The applicant proposed treatment of stormwater runoff with the use of a filtration basin located on the east side of the development. Based on the information and analysis provided regarding treatment of stormwater for TS and TPP, the filtration method proposed will be sufficient to meet the quality requirements of the City. However, an updated SMR must be provided that will include the inputs for the P8 model used for calculating these TS and TPP levels. Furthermore, rate controls have been shown to reduce post -construction flows from pre-existing flows, meeting City Code. However, insufficient abstraction is provided. Currently, 0.19 inches of runoff from the new Planning Commission The Moments of Chanhassen February 4, 2020 Page 13 of 19 impervious surfaces is being proposed for abstraction, while City standards is to capture 1.0 inch and the more restrictive rule of Riley Purgatory Bluff Creek Watershed District (RPBCWD) is 1.1 inches. The applicant has conducted soil borings and analysis identifying "Type D" soils (slow draining, "tight" soils with an infiltration rate of 0.06 in/hr), which could qualify the project site to be "restricted" through RPBCWD rules, lowering the required abstraction to 0.55 inches. Regardless, the proposed design for abstraction (0.19 inch) does not meet the rules and requirements of the City or RPBCWD. The applicant shall submit updated plans and modeling to provide for a required abstraction of 0.55 inches if the RPBCWD deems the site "restricted", and meet all conditions and comments to obtain a RPBCWD permit. If the site is deemed "non- restricted", then abstraction must meet the 1.1 inch abstraction rule. Lastly, the applicant shall provide an operation and maintenance plan (O&M) for the private stormwater BMPs. The O&M of private stormwater BMPs is required in perpetuity and must be approved by the Water Resources Coordinator, or their designee, to be recorded against the benefiting properties. UTILITIES Water service is available off W 78`s Street via a 12 inch DIP watermain. The applicant is proposing to wet tap two services for the building at the public watermain: a 4 inch domestic service and a 6 inch fire service. This approach is not approved as only one service is needed to adequately serve the development. One service will eliminate the need for unnecessary publicly maintained portions of service lines. Plans shall be resubmitted to achieve one wet tap location for one dual combined domestic and fire service line. This may require the applicant to size the service line to an 8" diameter, depending on their engineer's analysis and required fire flows. The applicant has also proposed a gate valve near the property line within the north boulevard adjacent to the public trail. As the wet tap will inherently have a gate valve at the tap location, the proposed redundant gate valve approximately 40 feet from the tap location will be owned and maintained by the property owner, and shall be located wholly on the private property. The City's sanitary sewer network is not available near the subject property, however the "Chanhassen Interceptor" sanitary main owned and operated by the Metropolitan Council Environmental Services (MCES) is directly adjacent to the property. The applicant is proposing to connect a private lateral directly to the MCES interceptor via a manhole located in MnDOT right-of-way. This method and approach has been submitted to MCES for review and has been approved, pending further comments and conditions from MCES. The proposal shows a directional bore of a 6 inch PVC sanitary sewer lateral through the development, across City right-of-way (W 78a' Street) south, and into the MCES manhole located in MnDOT right-of-way. The applicant will be required to apply for MnDOT right-of-way permits along with entering into a maintenance agreement with the City for the proposed inside drop within MCES' manhole. All proposed sanitary sewer lines will be privately owned and maintained. As such, no manholes shall be located within public right-of-way. PRELIMINARY CONSTRUCTION PLAN REVIEW Planning Commission The Moments of Chanhassen February 4, 2020 Page 14 of 19 Preliminary construction plan redlines will be provided to the applicant within ten (10) days, or a reasonable time thereafter, of the Planning Commission hearing date in order to assist and aid the developer, their engineers and their designers in addressing the comments provided within this report. Any recommendation of approvals does not constitute final approval of details, including but not limited to alignments, materials and points of access, connection or discharge, that are depicted or suggested in the application and/or subsequent plans. The applicant is required to submit detailed construction drawings and/or plat drawings for the project, as applicable. The City of Chanhassen Engineering and Public Works Department will review plans, in detail, when they are submitted and approve, reject or require modifications to the plans or drawings based upon conformance with City Standards, the Chanhassen Code of Ordinances and the professional engineering judgment of the City Engineer. LANDSCAPING AND TREE PRESERVATION MEMORANDUM TO: Sharmeen Al-Jaff, Senior Planner FROM: Jill Sinclair, Environmental Resources Specialist DATE: February 4, 2020 SUBJ: Moments of Chanhassen, Site Plan Review - Landscaping Minimum requirements for landscaping at the proposed development include 1,404 sq. ft. of landscaped area around the parking lot, 2 landscape islands or peninsulas, and 5 trees for the parking lot.

The quantity of boulevard trees is short, but with the combined planting space with the bufferyad, staff does not recommend increasing the planting quantities and finds the proposed landscaping acceptable. Shown on the removals plan is about 8 trees along the west property line scheduled for preservation. Staff inspected the trees and while they are of the age and type of species that would tolerate construction activity, staff doesn't recommend their preservation. The applicant has planned bufferyard plantings in the same location. The existing trees, mainly boxelder and ash, may be removed.

Planning Commission The Moments of Chanhassen February 4, 2020 Page 16 of 19 VARIANCE FINDINGS VARIANCE Sec. 20-58. - General conditions for granting. A variance may be granted if all of the following criteria are met: 1. 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. 2. 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. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. 3. That the purpose of the variation is not based upon economic considerations alone. 4. The plight of the landowner is due to circumstances unique to the property not created by the landowner. 5. The variance, if granted, will not alter the essential character of the locality. 6. Variances shall be granted for earth -sheltered construction as defined in M.S. 216C.06, subd. 14, when in harmony with this chapter. Finding: Staff has been working with the applicant and the watershed district to find a reasonable solution to developing this site. It contains multiple wetlands and Riley Creek is located along the northern edge of the site. A reasonable solution was to average the buffer around the wetlands and reduce the setback in return. Staff is recommending a minimum of 5 foot wetland setback and approval of the watershed district. The parking setback required by ordinance is 25 feet. The intent is to screen the parking lot. The applicant is providing adequate screening that will accomplish the intent of the ordinance. Staff is recommending approval of the parking setback variance.

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. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. 3. That the purpose of the variation is not based upon economic considerations alone. 4. The plight of the landowner is due to circumstances unique to the property not created by the landowner. The variance, if granted, will not alter the essential character of the locality 6. Variances shall be granted for earth -sheltered construction as defined in M.S. 216C.06, subd. 14, when in harmony with this chapter. Finding: The proposed development is consistent with the city's design requirements, the Comprehensive Plan, the zoning ordinance, the design standards, and the site plan review requirements. Staff is recommending approval of the request with conditions. The site design is compatible with the surrounding developments. It is functional and harmonious with the area. The Planning Commission regards the project as a reasonable use of the land. The overall design is sensitive to the city's image. 7. The planning report #2020-02 dated February 4, 2020, prepared by Sharmeen Al-Jaff et al, is incorporated herein. RECOMMENDATION The Planning Commission recommends that the City Council approve the proposed development including a Rezoning of 3.5 acres of property zoned RR, Rural Residential District to R-16 High Density Residential, and Site Plan Approval with Variances for the construction of a Continuing Care Retirement Facility. ADOPTED by the Chanhassen Planning Commission this 4`h day of February, 2020.

M 0 0 0 Z W m a M 0 a w z z f 0 0 w N wsb Memorandum To Erik Henricksen, City of Chanhassen From: Andi Moffatt, WSB Date. January 3, 2020 Re Moments of Chanhassen — Site Plan Review WSB Project No. R-013332-000 We have reviewed the Moments of Chanhassen plans dated December 20. 2019 for conformance with the Wetland Conservation Act and the City of Chanhassen Wetland Protection Ordinance. Based on this review, we have the following comments 1. Sheet C1 0 The wetland boundary of Basin 1 is incorrect and needs to be updated to reflect the approved delineated boundary. (It should match the boundary on Sheet V1.0). 2. Sheet C2.0. The plans need to be revised to clearly show both the wetland buffer and the structure setback from the buffer Currently, the plan appears to merge the two boundaries together. For Basin 1 (a Manage 3 Wetland), a permanent buffer of 16.5 feet needs to be shown around the wetland. It appears the plan may accommodate the full 16.5-foot buffer, but since it is not shown on the plans it is difficult to determine. The buffer for the Stream is 25 feet and also needs to be clearly shown on the plans. 3 Sheet C2.0. Basin 1 and the Stream both require a 30-foot structure setback from the edge of the buffer. These plans do not meet the setback requirement. The setback needs to be shown clearly with the proposed width (see example below from the City's standards). There is no structure setback averaging allowed within City Code. Therefore. a variance in the setback requirement needs to be requested per the city's variance request process as outlined in Article II, Division 3 of City Code. r "3 wEtwto RLMa TM \\"bgvles011poje sW13332W00\4dmnlDorsVWEMO-enem&c -Momerns Rew" 010320.d Erik Henricksen January 3, 2020 Page 2 4. Sheet 1-1.0. A buffer is an area immediately adjacent to a wetland that is left undisturbed. If the buffer is disturbed during construction, the area needs to be restored and maintained with native vegetation and noted with permanent monumentation. The buffers need to be shown clearly on these plans. It appears that grading is proposed within the buffer area of Basin 1. No restoration with native species, per City Code, is shown within the buffer in the disturbed areas. This needs to be revised on the plans along with showing the required buffer monumentation. 5. Sheet SW1.1. While this memo does not provide an exhaustive NPDES review, the plans do not conform to the Item 9.17 in the NPDES permit which states "[p]ermittees must preserve a 50 foot natural buffer or, if a buffer is infeasible on the site, provide redundant (double) perimeter sediment controls when a surface water is located within 50 feet of the project's earth disturbances and stormwater flows to the surface water. Permittees must install perimeter sediment controls at least 5 feet apart unless limited by lack of available space." There are not redundant features shown on the SWPPP plan. This concludes our review.

Civil Site Group DATE: 01 /06/2020 RE: Moments of Chanhassen, Chanhassen, MN Ms. AI-Jaff, We are requesting Municipal approvals to construct the Moments of Chanhassen. This one-story, 48 unit, 65,000 GSF building, includes a lower level resident amenity space, look -out units, storage and underground parking. Due to the existing site conditions & constraints, including dynamic topography, wetland location, and adjacent street frontage treatments, a traditional parking and building location, orientation, and setbacks have proven excessively difficult to achieve without drastically degrading the services and amenities required for this type of site use. Therefore, we are requesting flexibility in both the parking setback requirement and a reduction in setback along the smaller wooded wetland, through the use of wetland averaging. To help to mitigate the impacts of these setback modification requests, we are proposing significant enhancements to the building architecture, landscape improvements and screening. We are proposing enhanced screening along the south side of the parking lot and building foundation, as well as minimizing grading along the north side of the building so as to retain as much naturally occurring native plant material as possible. The Owners/Operators of the Moments of Chanhassen are proud be providing high quality senior care in their currently operating facility in Lakeville but are excited to start construction on this premier Chanhassen location in 2020. Thanks for your consideration and attention on this matter.

Existing Site Conditions: The site for this project is currently vacant with 0.0 acres of impervious surface. Soils: Soil borings have been completed by Haugo Geotechnical Services, Inc. dated January 5, 2018. Soils on site typically consist of Sandy Lean Clay fill with trace organic materials, gravel and wood over Sandy Lean Clay (CL) glacial till. On -site soils have a Hydrologic Soil Group (HSG) Type D designation with an infiltration rate of 0.06 in/hr. Site soils are poor for stormwater infiltration. Type D soils are modeled for the pervious areas in the HydroCAD models with a CN of 80. See the full Geotechnical Report at the end of this stormwater report. Groundwater: Groundwater has been identified in the soil borings at elevations ranging from 946.00 to 950.00. Groundwater was identified in two of the four soil borings taken near the proposed stormwater filtration basin at elevations 946.00 and 947.60. The bottom of the proposed filtration basin will be at 950.60, three feet above the highest groundwater elevation. Proposed Site: This project consists of the construction of a 48-unit memory care residential facility with associated parking, grading, utilities, and landscaping improvements. A filtration basin at the east end of the site will provide water quality and rate control to meet the requirements of the City of Chanhassen and the Riley -Purgatory -Bluff Creek Watershed District (RPBCWD). A restricted site designation is being sought for the volume abstraction requirement due to the poorly infiltrating soils. Tc (Time of Concentration) for all areas is assumed to be the minimum of 6 minutes for all sub catchments in the HydroCAD models. Impervious surfaces in the HydroCAD models use the recommended curve number of 98. Wetland Impacts: One delineated wetland exists on site. The wetland is classified as a Circular 39 type 2/1 wetland of approximately 4,269 sf in the north -central part of the site. This wetland will not be impacted as part of the project. www.CivilSiteGroui).com 4931 West 35' Street • Suite 200 • St. Louis Park • Minnesota • 55416 (612) 615-0060 i viSite G R O U P Requirements: Per Riley -Purgatory -Bluff Creek Watershed District (RPBCWD) and City of Chanhassen Rate Control: Runoff rate may not exceed existing conditions for the 2, 10 and 100-YR storm events and the 10-day snowmelt event. Atlas-14 rainfall data is used. Volume Abstraction: Stormwater runoff volume must be reduced by 1.1" over all new impervious surfaces (includes all newly constructed impervious surfaces, i.e. all impervious disturbed and reconstructed as well as new impervious). This project is seeking a restricted site designation from RPBCWD since the soils are poorly infiltrating. It is requested that the on - site BMP provide infiltration for the first 0.19" of new impervious surfaces. Water Quality: Stormwater BMPs shall remove 90% of total suspended solids (TSS) and 60% total phosphorus(TP). Proposed Storm Water Facilities: Pretreatment Pretreatment to the filtration basin is provided by a sumped catch basin/manhole with a 6' wide x 6' deep sump. A SAFL Baffle and Garbage Skunk will be installed in the manhole to dissipate energy and separate floatables and oils from the stormwater entering the filtration basin. This structure is labeled as CBMH 2 on the utility plan. The pretreatment device receives water from the primary roof drains on the building and two catch basins in the parking lot. The other pretreatment device is the Rain Guardian Turret at the northeastern end of the parking lot. This device receives runoff from the sloped drive aisle leading down to the garage door. According to a report from St. Anthony Falls Laboratory (SAFL), the Rain Guardian Turret TSS removal was as high as 88%. Rate Control practices proposed: Rate control for the project is provided by the proposed infiltration basin. The runoff rates for the 2-YR, 10-YR and 100-YR rainfall events, and the 10-day snowmelt event, will be less than the existing rates (utilizing Atlas-14). See the table below for the existing and proposed runoff rates for this project. www.CivilSiteGroui).com 4931 West 35' Street • Suite 200 • St. Louis Park • Minnesota • 55416 (612) 615-0060 :ivie G R O U P Rate Control Summary Table: Stormwater Rate Summary Drainage Area Existing Rate cfs 2-YR 2.80" 10-YR 4.2' 100YR &0' 10-DAY SNOWMELT EX7 O WETLAND/CREEK 5.61 11.20 18.83 2.71 EX2 O ADJ.

Volume/Water Quality practices proposed: As stated, this project is seeking a restricted site designation from RPBCWD since the soils on -site are poorly infiltrating. As designed, the abstraction of runoff on -site to the maximum extent practicable is 0.19" from the site's regulated impervious area. This abstraction will be accomplished with 7.2" of planting medium beneath the underdrain of the filtration basin. The 7.2" deep space over the entire surface area of the pond, and a 40% void ratio, corresponds to 877 cubic feet of abstraction. Although the maximum ponding depth in type D soils is 2.88", the corresponding depth in the planting medium is 7.2" due to the 40% void ratio. See the Volume/Water Quality Summary in the table below, as well as the P8 results at the end of this report which show the minimum 60% TP and 90% TSS removal rates for the site being met. www.CivilSiteGrouo.com 4931 West 351" Street • Suite 200 • St. Louis Park • Minnesota • 55416 (612) 615-0060 Ivi bite G R O U P Volume/Water Quality Summary: Drainage Area Required Infiltration Vol. Summary New Im v.

A brief summary of our results and recommendations is presented below. The soil borings completed with the building area encountered about 1 foot of vegetation and topsoil along with previously placed Fill that extended to depths ranging from about 12 to 29 feet below the ground surface. The Fill was composed of mostly clayey soils that contained organics, roots and fibers, and pieces of wood and concrete. Below the topsoil and Fill, the borings encountered native clayey soils that extended to the termination depths of the soil borings. The underlying native clays, in our opinion, are generally suitable for foundation support, but portions of the native clays had a soft consistency. The vegetation, topsoil, Fill and soft day soils are not suitable for foundation support and will need to be removed from within the building and oversize areas and replaced with suitable compacted engineered fill. The deepest deposits of Fill and/or soft native soils (about 29 feet) was encountered on the western portion of the site near boring SB-1 with soil borings elsewhere generally encountering about 12 to 17 feet of Fill and/or soft native soil. Soil corrections extending to about 29 feet may not be cost effective and, if possible, moving the building to the east might result in reduced soil corrections and the associated costs. If the building will include a lower level, removal of a significant portion of the Fill soil would likely be incidental to construction. Specific details regarding our procedures, results and recommendations follow in the attached geotechnical exploration report. 2825 Cedar Avenue S, Minneapolis, MN 55407 Thank you for the opportunity to assist you on this project.

The project will also include constructing the associated parking, drive lanes, and underground utilities. Civil Site Group requested a geotechnical exploration to evaluate the suitability of site soil conditions to support the proposed senior living center and provide recommendations for site development. 1.2 Purpose The purpose of this geotechnical exploration was to characterize subsurface soil and groundwater conditions and provide recommendations for foundation design, pavement design and construction of the proposed senior living center. 1.3 Site Description The project site consists of two parcels totaling 3.5 acres and is located at 1620 and 1660 Arboretum Boulevard in Chanhassen, MN. The lot was mostly open, and grass covered, with mature trees along the perimeter of the site. Riley Creek runs along the northern border of the site from nearby Lake Ann, which is about 1000 feet to the north of the site. The ground surface slopes to the north, with elevations at the soil boring locations ranging from about 9581h to 9721/2 feet mean sea level (MSL). 1.4 Scope of Services Our services were performed in accordance with the Haugo GeoTechnical Services LLC proposal dated October 31, 2017 and under the terns of our General Conditions. Our scope of services was generally limited to the following tasks: • Completing five (5) standard penetration test borings in the building area, extending to a nominal depth of 30 feet. • Completing three (3) standard penetration test borings in the pavement areas, extending to a nominal depth of 10 feet. One boring was extended to 15 feet due to the presence of existing Fill soils. • Obtaining GPS coordinates and elevations at the soil boring locations. • Visually/manually classifying soil samples recovered from the soil borings. • Performing laboratory tests on select soil samples. • Preparing soil boring logs describing the materials encountered and the results of groundwater level measurements. • Preparing an engineering report describing soil and groundwater conditions, and providing recommendations for foundation and pavement design. 1.5 Documents Provided We provided with a Surveyor's Certificate of the property which was prepared by Sunde Land Surveying, LLC and dated December 5, 2005. The Surveyors Certificate showed the property boundaries, city street(s) and existing topography. We were also provided a copy of a geotechnical engineering report prepared by STS Consultants dated January 13, 2006. The report presented the results of 10 soil borings taken across the project site. Briefly, the borings generally encountered about 6 to 15 feet of Fill overlying native glacial till deposits. The Fill was reported to contain "mixed organic bands' and possibly pieces of concrete. The report was prepared for construction of a surface parking lot with the potential for a future parking ramp. The report indicated that the soil conditions were generally suitable for support of a surface parking lot but soil corrections or a deep foundation system would be required to support a parking structure. 1.6 Locations and Elevations The soil boring locations were selected by Haugo GeoTechnical Services (HGTS) based on the anticipated construction and site access. The ground surface elevations at the soil boring locations were obtained by HGTS using GPS measuring equipment. The GPS measurements were based on the MN County Coordinate System (Carver County) in US Survey Feet using the GEOID09 (Conus) model. The approximate locations of the soil borings are shown on Figure 1, "Soil Boring Location Sketch," in the Appendix. The GPS boring locations are shown on Figure 2 in the Appendix. 2.0 FIELD PROCEDURES The standard penetration test borings were performed on December 181h,190, and 2011, 2017 by HGTS with a rotary drilling rig, using continuous flight augers to advance the boreholes. Representative samples were obtained from the borings, using the split -barrel sampling procedures in general accordance with A.STM Specification D-1586. In the split -barrel sampling procedure, a 2-inch O.D. split -barrel spoon is driven into the ground with a 140- pound hammer falling 30 inches. The number of blows required to drive the sampling spoon the last 12 inches of an 18-inch penetration is recorded as the standard penetration resistance value, or "N" value. The results of the standard penetration tests are indicated on the boring log. The samples were sealed in containers and provided to HGTS for testing and soil classification. Soil samples recovered from the borings were classified in general accordance with ASTM 2488, "Description and Identification of Soils (Visual/Manual Procedures). A field log of each boring was prepared by the HGTS drill crew. The logs contain visual classifications of the soil materials encountered during drilling, as well as the driller's interpretation of the subsurface conditions between samples and water observation notes. The final boring logs included with this report represent an interpretation of the field logs and include modifications based on visual/manual method observation of the samples. `A The soil boring logs, general terminology for soil description and identification, and classification of soils for engineering purposes are also included in the appendix. The soil boring logs identify and describe the materials encountered, the relative density or consistency based on the Standard Penetration resistance (N-value, "blows per foot') and groundwater observations. The strata changes were inferred from the changes in the samples and auger cuttings. The depths shown as changes between strata are only approximate. The changes are likely transitions, variations can occur beyond the location of the boring. 3.0 RESULTS 3.1 Soil Conditions Building Borings Soil borings SB-1 through SB-5 were completed within the proposed building footprint. These soil borings encountered about 1 foot of topsoil at the surface that consisted predominantly of silty clay. The topsoil contained some roots and was black to dark brown in color. Below the topsoil the borings encountered Fill materials that extended to depths ranging from about 12 to 29 feet below the ground surface. The Fill consisted of a variety of soil types consisting primarily of sandy lean clay with lesser amounts of silty clay, silty sand and sandy clay. The Fill varied in color from brown to dark brown to grey to black, and contained traces of organics, fibers, roots, wood, gravel and concrete. Below the topsoil and Fill the soil borings generally encountered native alluvial soils and/or glacial till soils that extended to the termination depths of the soil borings. The alluvial soils consisted of lean clay that was grey to mottled brown and grey in color, and portions contained traces of gravel. The penetration resistance values (N-Values), shown as blows per foot (bpf) on the boring logs within the alluvial soils ranged from 2 to 9 bpf. These values indicate the alluvial soils had a soft to rather stiff consistency. The glacial till soils consisted of sandy lean clay that was grey in color and contained traces of gravel. N-Values within the glacial till soils ranged from 9 to 13 bpf. These values indicate the glacial till soils had a rather stiff to stiff consistency. Parking Lot Borings Soil borings SB-6 to SB 8 were completed within the proposed parking areas on the north and east sides of the building. These soil borings encountered about 1 foot of topsoil at the surface that consisted predominantly of silty clay. The topsoil was black to dark brown in color. Borings SB-6 and SB-7 encountered native glacial till soils below the topsoil that extended to the termination depths of the soil borings. The glacial till was composed of sandy lean clay that was brown in color and contained traces of gravel and rust staining. N-Values within the glacial till soils ranged from 6 to 17 bpf. These values indicate the glacial till soils had a medium to very stiff consistency. 3 Boring SB-8 encountered about 11 feet Fill below the topsoil. The Fill was composed of silty sand and sandy lean clay that was black in color and contained traces of organics, wood and gravel. The topsoil and Fill were underlain by native alluvial soils that extended to the termination depth of the boring. The alluvial soils consisted of lean clay that was mottled brown and grey in color and contained traces of rust staining and gravel. N-Values within the alluvial soils ranged from 6 to 12 bpf. These values indicate the glacial till soils had a medium to rather stiff consistency. 3.2 Groundwater Groundwater was encountered in soil borings SB-1 to SB-5 while drilling and sampling or after removing the augers from the boreholes at depths ranging from 17 to 25 feet below the ground surface, corresponding to an elevation range of 946 to 950 feet MSL. Water levels were measured on the dates as noted on the boring logs and the period of water level observations was relatively short. Given the cohesive nature the Fill, alluvial and glacial till soils encountered, it is likely that insufficient time was available for possible perched groundwater to seep into the bore hole and rise to its hydrostatic level. Groundwater monitoring wells or piezometers would be required to more accurately determine water levels. Seasonal and annual fluctuations in the groundwater levels should be expected. The water level of Riley Creek along the north border of the site ranges between about 946 to 950 feet MSL. Lake Ann is located about 1000 feet to the north of the site. The MN DNR reports the Ordinary High Water Level (OHW) of Lake Ann to be 955.5 feet MSL. 3.3 Laboratory Testing Laboratory moisture content tests and organic content tests were performed on selected samples recovered from the soil borings. Laboratory moisture contents ranged from about 14 to 26 percent. These values indicate that portions of the soils were likely well above their assumed optimum soil moisture contents. Organic contents ranged from about 3 1/2 to 7 112 percent indicating the soils were slightly organic to organic. Results of the laboratory moisture content tests are also shown on the boring logs adjacent to the sample tested. 4 Table 1.

The site soils will generally be Type B soils under Department of Labor Occupational Safety and Health Administration (OSHA) guidelines. 4.0 DISCUSSION AND RECOMMENDATIONS 4.1 Proposed Construction Based on correspondence with Civil Site Group, we understand that specific plans for the senior living facility have not been finalized. Preliminary plans indicate that the building will likely be a single -story slab on -grade structure but could include a lower level. Specific structural drawings or design information was not available at the time of this report but based on the anticipated construction we assumed the building will include cast in -place concrete or masonry block foundation walls supported on concrete spread footings. Above grade construction is anticipated to include wood framing with a pitched roof and asphalt shingles. Based on these assumptions we anticipate perimeter footing loads on the order of 2 to 3 kips per lineal foot and interior column loads, if any, will be less than 100 kips. We anticipate the main floor will bear at or near existing site grades corresponding to about elevation 970. We further anticipate that soil bearing pressure(s) of 3,000 pounds per square foot (psf) will be required for foundation support. We have attempted to describe our understanding of the project. If the proposed loads exceed these values or if the design or location of the proposed building changes, we should be informed. Additional analyses and revised recommendations may be necessary. 4.2 Discussion The borings completed with the building area (SB-1 to SB-5) encountered about 1 foot of vegetation and topsoil along with previously placed Fill that extended to depths ranging from 12 to 29 feet below the ground surface. Underlying the topsoil and Fill, the borings encountered native alluvial clays and/or glacial till clay soils that extended to the termination depths of the soil borings. The soil conditions encountered in our soil borings were generally consistent with those identified and described in the STS Consultants geotechnical report. The vegetation and topsoil are compressible and not suitable for foundation support and will need to be removed and replaced with suitable compacted engineered fill to provide adequate foundation support. The Fill was composed of a variety of soil types, consisting of sandy lean clay, silty clay, silty sand and clayey sand and contained organics, fibers, wood and concrete. In addition, the Fill varied in color with much of it black in color. Laboratory test results indicated it was slightly organic to organic. Organic soils or soil containing organic materials are generally compressible and poor -quality soil for foundation support. In addition, portions of the alluvial clay soils had a soft to rather soft consistency. The soft clays are also generally compressible and likewise, are poor -quality soil for foundation support. For these reasons we do not recommend supporting the proposed senior living facility on the Fill or soft alluvial clays. The underlying stiffer native alluvial clays and glacial till clay soils, in our opinion, are generally suitable for foundation support. The deepest deposits of Fill and/or soft native soils (about 29 feet) was encountered in soil boring SB-1 with soil borings SB-2 thru SB-5 generally encountering about 12 to 17 feet of Fill and/or soft native soil. Soil corrections extending to about 29 feet may not be cost effective and if possible, moving the building to the east might result in reduced soil corrections and the associated costs. If the building will include a lower level, removal of a significant portion of the Fill and soft native soil would likely be incidental to construction. As noted above much of the Fill was "black" in color and slightly organic to organic and will likely not be suitable for re -use as structural fill. It maybe possible to reuse these soil in "green areas" such as landscaping berms. Soil borings SB-6 and SB-7 were completed in the proposed parking areas on the east side of the building. The ground surface in the vicinity of these borings was near elevation 9581/2. We assume the parking lot(s) will match the approximate main floor elevations of the building which is anticipated to be near 971. Because of that we anticipate that about 12 to 13 feet of fill could be required to attain parking lot grades. Groundwater was encountered in the soil borings while drilling and after auger removal from the boreholes at depths ranging from 17 to 29 feet below the ground surface. We anticipate that groundwater will be encountered during deeper soil corrections and anticipate that dewatering will be required. The following sections provide recommendations for supporting the proposed senior living facility on typical frost depth footing following soil corrections. 0 4.3 Foundation Preparation Excavations We recommend that all vegetation, topsoil, existing Fill, soft alluvial clays or other unsuitable soils be removed from the proposed building and oversize areas. Table 2 below summarizes the anticipated excavation depths at the soil boring locations. Excavation depths may vary and could be deeper. Table 2. Anticipated Gradine Excavation Depths Boring Number Measured Surface Elevation feet Anticipated Excavation Depth (feet)* Anticipated Excavation Elevation (feet)* Groundwater Elevation (feet)* SBA 970.0 29 941 950 SB-2 969.8 13 957 9491h SB-3 972.7 17 9551h 9471/2 SD-4 964.6 17 9471/2 9471/2 SB-5 971.0 17 954 946 SB-6 958.7 1(Parking) 9571h NE SB-7 958.3 1(Parking) 9571/2 NE SB-8 967.9 1(Parking) 967 NE *Excavation depths and elevations were rounded to the nearest 1h foot. NE = Not Encountered Oversizing In areas where the excavations extend below the proposed footing elevations, the excavation requires oversizing. We recommend the perimeter of the excavation be extended a foot outside the proposed footprint for every foot below footing grade (1H:1V oversizing). The purpose of the oversizing is to provide lateral support of the foundation. Fill Material Additional fill required to attain site grades can consist of any non -organic mineral soil provided it is free of debris or other deleterious materials. As mentioned in the Discussion section, the existing Fill was mostly black in color and slightly organic to organic. The existing Fill will generally not be suitable for re -use as structural fill. It may be possible to reuse these soil in "green areas' such as landscaping berms. If construction is anticipated to occur during the winter months we recommend granular material meeting the ASTM Classification SP or SP-SM for ease in compaction. For backfill/fill within 3 feet of the groundwater table we recommend using granular soil with less than 5 percent passing the number 200 sieve and at least 50 percent retained on the number 40 sieve. Backfilling We recommend that engineered fill placed to establish foundation grades be compacted to a minimum of 98 percent of its standard Proctor density (ASTM D 698). We recommend that engineered fill placed to establish floor slab grades be compacted to a minimum of 95 percent of its standard Proctor density (ASTM D 698). Granular fill classified as SP or SP-SM should be placed within 65 percent to 105 percent of its optimum moisture content as determined by the standard Proctor. Other fill soils, if any, should be placed within 3 percentage points above and 1 percentage point below its optimum moisture content as determined by the standard Proctor. All fill should be placed in thin lifts 7 and be compacted with a large self-propelled vibratory compactor operating in vibratory mode. In areas where fill depths will exceed 10 feet we recommend that compaction levels be increased to minimum of 100 percent of the materials standard Proctor density. Even with the increased compaction levels a construction delay may be appropriate to allow for post construction settlement of the fill mass. Fill and backfill placed on slopes, if any, must be "benched" into the underlying suitable soil to reduce the potential for slip planes to develop between the fill and underlying soil. We recommend "benching" or excavating into the slope at 5 feet vertical intervals to key the fill into the slope. We recommend each bench be a minimum of 10 feet wide. Foundations We recommend the perimeter footings bear a minimum of 42 inches below the exterior grade for frost protection. The interior footings may be placed immediately below the floor slab provided construction does not occur during below freezing weather conditions. Footings in unheated should bear at least 5 feet below grade for frost protection. We anticipate the foundations and floor slabs will bear on compacted engineered fill over native clay soils. With the building pad prepared as recommended it is our opinion the footings can be designed for a net allowable bearing pressure up to 3,000 pounds per square foot (psf). We anticipate total and differential settlement of the foundations will be less than 1 inch and lh inch, respectively across an approximate 30-foot span. 4.4 Dewatering Groundwater was encountered in the soil borings while drilling and after auger removal from the boreholes at depths ranging from 17 to 29 feet below the ground surface. We anticipate that groundwater will be encountered during deeper soil corrections anticipate that dewatering will be required. Where dewatering is required we recommend the groundwater level be temporarily lowered to a minimum of 2 feet below the lowest anticipated excavation elevation to allow for construction. We recommend that a dewatering contractor be consulted to review the soil boring logs, develop a dewatering plan and evaluate the impact of dewatering on adjacent structures. 4.5 Below Grade Walls We anticipate that the proposed building will be a slab on -grade structure with no below grade or basement levels. However, we understand that building design has not been finalized and the building could include a lower level. Foundation walls or. below grade (basement) walls will have lateral loads from the surrounding soil transmitted to them. We recommend general waterproofing of the below grade walls even with the use of free -draining backfill because of the potential cost impacts related to seepage after construction. Unless a drainage composite is placed against the backs of the exterior perimeter below -grade walls we recommend that backfill placed within 2 feet of those wall consist of sand having less than 50 percent of the particles by weight passing the #40 sieve and less than 5 percent of the particles by weight passing the #200 sieve. We recommend the balance of the backfill for the walls consist of sand however the sand may contain up to 20 percent of the particles by weight passing the #200 sieve. We recommend installing drain tile behind the below grade walls, adjacent to the wall footing and below the slab elevation. Preferably the drain tile should consist of perforated pipe embedded in gravel. A geotextile filter fabric should encase the pipe and gravel. The drain tile should be routed to a storm sewer, sump pump or other suitable disposal site. Active earth pressures can be used to design the below grade walls if the walls are allowed to rotate slightly. If wall rotation cannot be tolerated, then below grade wall design should be based on at -rest earth pressures. We recommend the following soil parameters be used for below grade/retaining wall design, shown in Table 3. These design parameters are based on the assumptions that the walls are drained, there are no surcharge loads within a horizontal distance equal to the height of the wall and the backfill is level. Table 3. Soil Parameters Estimated Estimated Active Passive Unit Friction At -Rest Soil Soil Soil Type Weight Angle re Pressure P(pcf) Pressure Pressure (degrees) Sand 125 32 55 35 400 SP & SP-S Clays 135 28 70 50 375 CL Resistance to lateral earth pressures will be provided by passive resistance against the wall footings and by sliding resistance along the bottom of the wall footings. We recommend a sliding coefficient of 0.35. This value does not include a factor of safety. 4.6 Interior Slabs We anticipate that the floor subgrade will consist of a "sand cushion' over compacted clay fill. For "clean' sand (SP or SP-SM) soils a subgrade modulus (k value) of 200 pounds per square inch of deflection may be used to design the floor. If floor coverings or coatings less permeable than the concrete slab will be used, we recommend that a vapor retarder or vapor barrier be placed immediately beneath the slab. Some contractors prefer to bury the vapor barrier or vapor retarder beneath a layer of sand to reduce curling and shrinkage, but this practice often traps water between the slab and vapor retarder or barrier. Regardless of where the vapor retarder or vapor barrier is placed, we recommend consulting the floor covering manufacturer regarding the appropriate type, use and installation of the vapor retarder or vapor barrier to preserve the warranty. 0 We recommend following all state and local building codes in regards to a radon mitigation plan beneath interior slabs. 4.7 Exterior Slabs Portions of the exterior slabs will likely be underlain by silty and clayey soils which are considered moderately frost susceptible. If the silty/clayey soils become saturated and freeze, significant heave may occur. This heave can be a nuisance in front of doors and at other critical grade areas. One way to help reduce the potential for heaving is to remove the frost - susceptible soils below the slabs down to bottom of footing grades, and replace them with non -frost -susceptible backfill consisting of sand having less than 5 percent of the particles by weight passing the number 200 sieve. Sand meeting this gradation is likely not available on - site. If this approach is used and the excavation bottoms terminate in non -free draining granular soil we recommend a drain tile be installed along the bottom outer edges of the excavation to collect and remove any water that may accumulate within the sand. The bottom of the excavation should be graded away from the building. If the banks of the excavations to remove the frost -susceptible soils are not sloped, abrupt transitions between the frost -susceptible and non -frost -susceptible backfill will exist along which unfavorable amounts of differential heaving may occur. Such transitions could exist between exterior slabs and sidewalks, between exterior slabs and pavements and along the slabs themselves if the excavations are confined to only the building entrances. To address this issue we recommend sloping the excavations to remove frost -susceptible soils at a minimum 3:1(horizontal:vertical) gradient. An alternative method of reducing frost heave is to place a minimum of 2 inches of extruded polystyrene foam insulation beneath the slabs and extending it about 4 feet beyond the slabs. The insulation will reduce frost penetration into the underlying soil and reduce heave. Six to 12 inches of granular soil is typically placed over the insulation to protect it during construction. Another alternative for reducing frost heave is to support the slabs on frost depth footings. A void space of at least 4 inches should be provided between the slab and the underlying soil to allow the soil to heave without affecting the slabs. 4.8 Site Grading and Drainage We recommend the site be graded to provide positive run-off away from the proposed building. We recommend landscaped areas be sloped a nummum of 6 inches within 10 feet of the building and slabs be sloped a minimum of 2 inches. In addition, we recommend downspouts with long splash blocks or extensions. We recommend the lowest floor grades be constructed to maintain at least a 4-foot separation between the lowest floor slab and observed groundwater and at least a 2400t separation between the lowest floor slab and 100 year flood levels of any adjacent surface water features such as wetlands, ponds or creeks. 10 4.9 Utilities We anticipate that the utilities will be supported on engineered fill placed following soil corrections or native alluvial and glacial till soils which in our opinion are suitable for pipe support. We recommend removing all topsoil, Fill, very loose/soft or other unsuitable soil, if encountered, beneath utilities prior to placement. We recommend bedding material be thoroughly compacted around the pipes. We recommend trench backfill above the pipes be compacted to a minimum of 95 percent beneath slabs and pavements, the exception being within 3 feet of the proposed pavement subgrade, where 100 percent of standard Proctor density is required. In landscaped areas we recommend a minimum compaction of 90 percent. Groundwater was encountered in the soil borings while drilling and after auger removal from the boreholes at depths ranging from 17 to 29 feet below the ground surface. We do not anticipate that groundwater will be encountered during utility construction and do not anticipate that dewatering will be required. 4.10 Bituminous Pavements We recommend that pavements be designed and constructed in accordance with City of Chanhassen standard plates. The following paragraphs provide general pavement recommendations in the absence of City of Chanhassen standard plates. We anticipate that the parking areas will be used predominantly by automobiles and light trucks with occasional use by heavier vehicles including but not limited to food service delivery trucks and garbage trucks. Based on the assumed traffic types we anticipate that both light duty and heavy duty pavements will be required. Based on the assumed traffic types we estimate the light duty pavements will be subjected to Equivalent Single Axel Loads (FSAL's) up to 50,000 over a design life of 20 years and heavy duty pavements will be subjected to FSAL's up to about 75,000 over a 20 year design life. We recommend removing all vegetation, topsoil or other unsuitable materials from beneath the pavement subgrade. We recommend the existing Fill soils be further evaluated during construction. Prior to placing the aggregate base we recommend compacting and proof - rolling the subgrade soil to provide a more uniform surface and to identify soft, weak, loose or unstable areas that may require additional subcuts. As mentioned in the Discussion section, soil borings SB-6 and SB-7 were completed in the proposed parking areas on the east side of the building. The ground surface in the vicinity of these borings was near elevation 958 lh. We assume the parking lot(s) will match the approximate main floor elevations of the building which is anticipated to be near 971. Because of that we anticipate that about 12 to 13 feet of fill will be required to attain parking lot grades. Backfill to attain pavement subgrade elevation can consist of any mineral soil provided it is free of organic material or other deleterious materials. Granular fill classified as SP or SP-SM, if used, should be placed within 65 percent to 105 percent of its optimum moisture content as 11 determined by the standard Proctor. Other fill soils should be placed with moisture contents within a range of 1 percentage point below and 3 percentage points above its optimum moisture content. The upper 3 feet of fill and backfill should be compacted to a minimum of 100 percent of its standard Proctor maximum dry density. R-Value testing was beyond the scope of this project. The soil borings generally encountered cohesive soils corresponding to the ASTM Classification of CL which typically have R-Values ranging from 6 to 18. It is our opinion that an R-Value of 12 can be used for pavement design. It should be noted that the pavement sections presented below are not absolutes. Depending on serviceability expectations, material availability, and cost, there will be circumstances under which alternative sections will be more practicable. The placement of a sand subbase to support the pavements could potentially reduce the required pavement sections. For light duty pavements subjected to a maximum of 50,000 ESAL's and a subgrade R-Value of 12 we recommend a pavement section consisting of a minimum of 31h inches of bituminous over a minimum of 9 inches of MN/DOT Class 5 aggregate base. For medium to heavy duty pavements subjected to a maximum of 75,000 ESAL's and a subgrade R-Value of 12 we recommend a pavement section consisting of a minimum of 4 inches of bituminous over a minimum of 12 inches of MN/DOT Class 5 aggregate base. 4.11 Materials and Compaction We recommend specifying aggregate base meeting MN/DOT Class 5 aggregate base. We recommend the aggregate base be compacted to 100 percent of its maximum standard Proctor. We recommend that the bituminous pavements be compacted to at least 92 percent of the maximum theoretical density. We recommend specifying concrete that has a minimum 28 day compressive strength of 4,000 psi, and a modulus of rupture of at least 600 psi. We recommend Type I cement meeting the requirements of ASTM C150. We recommend specifying 5 to 7 percent entrained air for exposed concrete to provide resistance to freeze -thaw deterioration. We also recommend using a water/cement ratio of 0.45 or less for concrete exposed to deicers. 5.0 CONSTRUCTION CONSIDERATIONS 5.1 Excavation The soil encountered in the borings consisted predominantly of cohesive (clay) soils meeting the ASTM Classifications CL and CLrML. The site soils will generally be Type B soils under Department of Labor Occupational Safety and Health Administration (OSHA) guidelines. Temporary excavations in Type C soils should be constructed at a minimum of 1 foot horizontal to every 1 foot vertical within excavations. Slopes constructed in this manner may 12 still exhibit surface sloughing. If site constraints do not allow the construction of slopes with these dimensions then temporary shoring may be required. 5.2 Observations A geotechnical engineer or qualified engineering technician should observe the excavation subgrade to evaluate if the subgrade soils are similar to those encountered in the borings and adequate to support the proposed construction. 5.3 Backfill and Fills Site soils that will be excavated and reused as backfill and fill appear to be above their assumed optimum moisture content. We anticipate it might be necessary to moisture condition (dry) these soils to achieve the recommended compaction. We recommend that fill and backfill be placed in lifts not exceeding 4 to 12 inches, depending on the size of the compactor and materials used. 5.4 Testing We recommend density tests of backfill and fills placed during construction of the facility. Samples of the proposed materials should be submitted to our laboratory prior to placement for evaluation of their suitability and to determine their optimum moisture content and maximum dry density (Standard Proctor). 5.5 Winter Construction If site grading and construction is anticipated to proceed during cold weather, all snow and ice should be removed from cut and fill areas prior to additional grading and placement of fill. No fill should be placed on frozen soil and no frozen soil should be used as fill or backfill. Concrete delivered to the site should meet the temperature requirements of ASTM and/or ACI. Concrete should not be placed on frozen soil. Concrete should be protected from freezing until the necessary strength is obtained. Frost should not be permitted to penetrate below the footings. 6.0 PROCEDURES 6.1 Soil Classification The drill crew chief visually and manually classified the soils encountered in the borings in general accordance with ASTM D 2488, "Description and Identification of Soils (Visual - Manual Procedure)". Soil terminology notes are included in the Appendix. The samples were returned to our laboratory for review of the field classification by a geotechnical engineer. Samples will be retained for a period of 30 days. 13 6.2 Groundwater Observations Immediately after taking the final samples in the bottom of the borings, the hole was checked for the presence of groundwater. Again, at the end of the drilling day, the borings were re- checked for the presence of groundwater with the levels and time delay being noted on the boring logs. 7.0 GENERAL 7.1 Subsurface Variations The analyses and recommendations presented in this report are based on data obtained from a limited number of soil borings. Variations can occur away from the borings, the nature of which may not become apparent until additional exploration work is completed or construction is conducted. A reevaluation of the recommendations in this report should be made after performing on -site observations during construction to note the characteristics of any variations. The variations may result in additional foundation costs and it is suggested that a contingency be provided for this purpose. It is recommended that we be retained to perform the observation and testing program during construction to evaluate whether the design is as expected, if any design changes have affected the validity of our recommendations, and if our recommendations have been correctly interpreted and implemented in the designs, specifications and construction methods. This will allow correlation of the soil conditions encountered during construction to the soil borings and will provide continuity of professional responsibility. 7.2 Review of Design This report is based on the design of the proposed structures as related to us for preparation of this report. It is recommended that we be retained to review the geotechnical aspects of the design and specifications. With the review we will evaluate whether any changes have affected the validity of the recommendations and whether our recommendations have been correctly interpreted and implemented in the design and specifications. 7.3 Groundwater Fluctuations We made water level measurements in the borings at the times and under the conditions stated on the boring logs. The data was interpreted in the text of this report. The period of observation was relatively short and fluctuations in the groundwater level may occur due to rainfall, flooding, irrigation, spring thaw, drainage, and other seasonal and annual factors not evident at the time the observations were made. Design drawings and specifications and construction planning should recognize the possibility of fluctuations. 14 7.4 Use of Report This report is for the exclusive use of Civil Site Group, Inc. and their design team to use to design the proposed structures and prepare construction documents. In the absence of our written approval, we make no representation and assume no responsibility to other parties regarding this report. The data, analysis and recommendations may not be appropriate for other structures or purposes. We recommend that parties contemplating other structures or purposes contact us. 7.5 Level of Care Haugo GeoTechnical Services, LLC has used the degree of skill and care ordinarily exercised under similar circumstance by members of the profession currently practicing in this locality. No warranty expressed or implied is made. 15 APPENDIX Iz ik S II` � 'y✓ �.

The site was approximately 3.49 acres in size, and was located at Sec. 10, T116N, R23W, Chanhassen, Minnesota. See Figure 1 for a Site Location Map. The purpose of the investigation was to identify areas within the project boundary meeting the technical criteria for wetlands, delineate the jurisdictional extent of the wetland basins, and classify the wetland habitat according to the 1987 U.S. Army Corps of Engineers Wetland Delineation Manual and the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation: Midwest Region. Wetlands are areas that are saturated or inundated with surface and or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in hydric soil conditions. Examples of wetlands include seasonally flooded basins, floodplain forests, wet meadows, shallow and deep marshes, shrub swamps, wooded swamps, fens, and bogs. Wetland boundaries were determined through a routine analysis of the vegetation, soils and hydrology which must all show wetland characteristics for an area to be delineated as a wetland. One basin was delineated within the project area, which is summarized below and shown on Figure 5.

Antecedent precipitation data can be found in Appendix A. The growing season in this area is approximately from mid -April to mid -October, when the air temperature averages above 28 degrees F. This delineation was completed during the growing season. 2.1.2 National Wetlands Inventory The National Wetlands Inventory (NWI) identified no wetlands within the property boundary (Figure 2). 2.1.3 Web Soil Survey The National Resource Conservation Service Web Soil Survey (Figure 7) identified the following soils: Soil H dric Rating Kilkenny -Lester loams 0 !EE Lester-Kilkennyloams 0 Lester -Kilkenny complex 5 2.1.4 Public Waters Inventory The Minnesota Department of Natural Resources Public Waters Inventory shows that one public water exists on the property: Riley Creek, which runs approximately 445 feet along the northern edge of the property (Figure 4).

Transects were established in representative areas of each wetland. Each transect consisted of one sample point within the wetland and one sample point in upland. Other areas which have one or more of the wetland vegetation, soils, or hydrologic characteristics present, or where questionable conditions exist may also have been sampled. Data sheets for each sample point are available in Appendix B. Wetland classifications discussed in the text are set forth in Wetlands and Deepwater Habitats of the United States (FWS/OBS Publication 79/31, Cowardin et al. 1979) and Wetlands of the United States (USFWS Circular 39, Shaw and Fredine, 1971.) Additionally, plant community types as named by Eggers and Reed (1998) are given. Wetland edges were marked with orange numbered pin flags or "wetland boundary' flagging tape on vegetation as site conditions warrant. Sample points are marked with orange numbered pin flags. Any wetlands or sample points were mapped using GPS 2.2.1 Vegetation The plant species within the parcel were cataloged and assigned a wetland indicator status according to: Lichvar, R.W., D.L Banks, W.N. Kirchner, and N.0 Melvin, 2016. The National Wetland Plant List: 2016 Wetland Ratings, Phytoneuron 2016-30: 1-17, In the text of this report and on the enclosed data forms, the plant indicator status follows the plant's scientific name unless a status has not been assigned. The hydrophytic plant criterion is met when more than 50 percent of the dominant species by the 50/20 rule for each stratum (herb, shrub/sapling, tree, and woody vine) were assigned an obligate (OBL)', facultative wet (FACW), and/or facultative (FAC) wetland status. 1 OBL=Obligate Wetland, occurs an estimated 99% in wetlands. FACW=Facuitative Wetland, has an estimated 67%-99% probability of occurrence in wetlands. FAC=Facultative, is equally likely to occur in wetlands and non -wetlands. 34%-66% probability. FACU=Facultative Upland, occurs in wetlands only occasionally. 1%-23% probability. UPL=Upland, almost never occurs in wetlands, <1% probability. NI= No Indicator, insufficient information available to determine an indicator status. Positive or negative sign previously indicated a frequency toward higher (+) or lower (-) frequency of occurrence within a category.

If a soil exhibits the indicators of a hydric soil or is identified as a hydric soil the hydric soil criterion is met. The break between hydric and non-hydric soils was determined by excavating soil pits along transects crossing the wetland/upland eco-tone and evaluating the soil colors, textures, and presence or absence of redoximorphic indicators (i.e., mottles, gley or oxidized rhizospheres). Hydric Soil Indicators for the Midwest Region were noted as presented in the National Technical Committee for Hydric Soils Field Indicators of Hydric Soils in the United States version 8.1 (USDA NRCS 2017) if present at each sample point. Upper soil profiles were also compared to the mapped or inclusionary soil series found in the sample area for soil identification purposes. 2.2.3 Cautions Used in Applying the Field Indicators of Hydric Soils There are hydric soils with morphologies that are difficult to interpret. These include soils with black, gray, or red parent material; soils with high pH; soils high or low in content of organic matter, recently developed hydric soils, and soils high in iron inputs. In some cases, we do not currently have indicators to assist in the identification of hydric soils in these situations. If the soil meets the definition of a hydric soil, the lack of an indicator does not preclude the soil from being hydric. The indicators were developed mostly to identify the boundary of hydric soil areas and generally work best on the margins. Not all the obviously wetter hydric soils will be identified by the indicators. Redoximorphic features are most likely to occur in soils that cycle between anaerobic (reduced) and aerobic (oxidized) conditions. Morphological features of hydric soils indicate that saturation and anaerobic conditions have existed under either contemporary or former hydrologic regimes. Where soil morphology seems inconsistent with the landscape, vegetation, or observable hydrology. it may be necessary to obtain the assistance of an experienced soil or wetland scientist to determine whether the soil is hydric. To clarify, when investigating hydric soils in this area, one must consider the following: • Many of these soils have black or gray parent materials. • Many of the soils have a high organic matter content. • The hydric soil margin is typically higher than the wetland boundary margin on the site. • Not all the obviously wetter soils will be identified by the indicators. Many of the hydric soils are Mollisols which are classic problem hydric soils in many cases.

The basin was dominated by Slough Sedge (OBL), Reed Canary Grass (FACW), and Black Willow (OBL). Hydrology indicators included A2 (high water table), A3 (saturation), D2 (geomorphic position) and D5 (FAC neutral test), Wetland soils met indicators F3 (depleted matrix), Al (depleted below dark surface), Al2 (thick dark surface), and F6 (redox dark surface). Adjacent upland was typically dominated by Tall Goldenrod (FACU), Reed Canary Grass (FACW), Kentucky Bluegrass (FAC), and Common Buckthorn (FAC). Primary hydrology indicators were not observed at the upland sample point. Hydric soil indicator F6 was found in the upland at sample point 1-2- UP. The wetland boundary followed a change in vegetation from wetland to upland plant communities, as well as a gradual to distinct change in topography. The basin was not shown as a wetland on the NWI map (Figure 2) and was located within an area mapped as Kilkenny -Lester loam (RATING=O) by the Web Soil Survey (Figure 7). Sample data sheets 1-UP/1-WET through 1-4-UP/1-4-WET in Appendix B correspond to this basin 4.0 CONFIRMATION OF JURISDICTIONAL STATUS Jacobson Environmental is submitting this report to the client and regulatory agencies to request a wetland boundary and type determination. We have enclosed an official WCA Approval of Wetland Type and Boundary form in Appendix D along with a USCOE wetland delineation concurrence request. 5.0 CERTIFICATION I certify that this wetland delineation meets the standards and criteria described in the 1987 U.S. Army Corps of Engineers Wetland Delineation Manual and the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation: Midwest Region.

Include all anticipated impacts, including those expected to be temporary. Attach an overhead view map, aerial photo, and/or drawing showing all of the aquatic resources in the project area and the location(s) of the proposed impacts. Label each aquatic resource on the map with a reference number or letter and identify the impacts in the following table. Type of County, Major Aquatic Aquatic Impact (fill, Duration of Existing Plant B Watershed #, Resource ID (as Resource excavate, Impact Size of Overall Size o Community and Bank noted on Type drain, or Permanent (P) Impact' Aquatic Type(s) in Service Area # overhead view) (wetland, lake, remove or Temporary Resource a Impact Area P of Impact tributary etc.) vegetation) i (T) Areas 'If impacts are temporary; enter the duration of the impacts in days next to the "T". For example, a project with a temporary access fill that would be removed after 220 days would be entered "T (220)". 'Impacts less than 0.01 acre should be reported in square feet. Impacts 0.01 acre or greater should be reported as acres and rounded to the nearest 0.01 acre. Tributary impacts must be reported in linear feet of impact and an area of impact by indicating first the linear feet of impact along the flowline of the stream followed by the area impact in parentheses). For example, a project that impacts 50 feet of a stream that is 6 feet wide would be reported as 50 ft (300 square feet). 3This is generally only applicable if you are applying for a de minimis exemption under MN Rules 8420.0420 Subp. 8, otherwise enter "N/A". °Use Wetland Plants and Plant Community Types of Minnesota and Wisconsin 31d Ed. as modified in MN Rules 8420.0405 Subp. 2. 3Refer to Major Watershed and Bank Service Area maps in MN Rules 8420.0522 Subp. 7.

' The term "impact" as used in this joint application form is a generic term used for disclosure purposes to identify activities that may require approval from one or more regulatory agencies. For purposes of this form it is not meant to indicate whether or not those activities may require mitigation/replacement. Minnesota Interagency Water Resource Application Form February 2014 Page 4 of I I Project Name and/or Number: 2018-295 Attachment A Request for Delineation Review, Wetland Type Determination, or Jurisdictional Determination By submission of the enclosed wetland delineation report, I am requesting that the U.S. Army Corps of Engineers, St. Paul District (Corps) and/or the Wetland Conservation Act Local Government Unit (LGU) provide me with the following (check all that apply): ® Wetland Type Confirmation ® Delineation Concurrence. Concurrence with a delineation is a written notification from the Corps and a decision from the LGU concurring, not concurring, or commenting on the boundaries of the aquatic resources delineated on the property. Delineation concurrences are generally valid for five years unless site conditions change. Under this request alone, the Corps will not address the jurisdictional status of the aquatic resources on the property, only the boundaries of the resources within the review area (including wetlands, tributaries, lakes, etc.). ® Preliminary Jurisdictional Determination. A preliminary jurisdictional determination (PJD) is a non -binding written indication from the Corps that waters, including wetlands, identified on a parcel may be waters of the United States. For purposes of computation of impacts and compensatory mitigation requirements, a permit decision made on the basis of a PJD will treat all waters and wetlands in the review area as if they are jurisdictional waters of the U.S. PJDs are advisory in nature and may not be appealed. ❑ Approved jurisdictional Determination. An approved jurisdictional determination (AJD) is an official Corps determination that jurisdictional waters of the United States are either present or absent on the property. AJDs can generally be relied upon by the affected party for five years. An AJD may be appealed through the Corps administrative appeal process. In order for the Corps and LGU to process your request, the wetland delineation must be prepared in accordance with the 1987 Corps of Engineers Wetland Delineation Manual, any approved Regional Supplements to the 1987 Manual, and the Guidelines for Submitting Wetland Delineations in Minnesota (2013). htto•//www mvi)usace armv mil/Missions/Regulatory/DelineationJDGuidance.aspx Minnesota Interagency Water Resource Application Form February 2014 Page 5 of 11 Appendix E Exhibit I Field data sheet reference (if applicable): Wetland Hydrology from Aerial Imagery — Recording Form Project Name: Moments of Chanhassen Date: 12/2/18 County: Carver Investigator: ACM Legal Description (T, It, S): 116N 23 W 10 Summary Table 64-2OOe3t) Image Source Climate Condition (w� dry, normal)' Image Interpretation(s) Area: A Area: Area: Area: Area: USGS N ss W USGS N NV 4-2004 USGS W -2008 USGS -2009 USGS NV 5-2010 USGS N NV -2011 USGS N NV 9-2013 USGS N NV 8-2015 USGS W 3-2016 USGS N NV 4-2017 USGS D 4-2 Normal Climate Condition Area: A Area: Area: I Area: Area: Number 19 Number with wet signatures Percent with wet signatures 11 _ lay WS - wetland signature SS - soil wetness signature CS - crop stress NC - not cropped AP - altered pattern NV - normal vegetative cover DO - drowned out SW - standing water NSS - no soil wetness signature Other labels or comments • Use abmekeyo label image mterpmutions.

The parcel for review falls within the shoreland overlay of this tributary stream from Lake Ann and is subject to the rules laid out in the City's shoreland ordinance. All bluff areas within 300 feet of the stream should be identified and labeled on plans. Grading and stormwater outfalls should not be located within the bluff. Additionally, DNR public water streams require an average 50-ft vegetated buffer. I see that the wetland buffer is being met, but I'm unable to determine whether the stream buffer is also being met.

Civil Site Group DATE: 12/20/2019 RE: Moments of Chanhassen, Chanhassen, MN Ms. AI-Jaff, We are requesting Municipal approvals to construct the Moments of Chanhassen. This one-story, 48 unit, 65,000 GSF building, includes a lower level resident amenity space, look -out units, storage and underground parking. Due to the existing site conditions & constraints, including dynamic topography, wetland location, and adjacent street frontage treatments, a traditional parking and building location, orientation, and setbacks have proven excessively difficult to achieve without drastically degrading the services and amenities required for this type of site use. Therefore, we are requesting flexibility in both the parking setback requirement and a reduction in setback along the smaller wooded wetland, through the use of wetland averaging. To help to mitigate the impacts of these setback modification requests, we are proposing significant enhancements to the building architecture, landscape improvements and screening. We are proposing enhanced screening along the south side of the parking lot and building foundation, as well as minimizing grading along the north side of the building so as to retain as much naturally occurring native plant material as possible. The Owners/Operators of the Moments of Chanhassen are proud be providing high quality senior care in their currently operating facility in Lakeville but are excited to start construction on this premier Chanhassen location in 2020. Thanks for your consideration and attention on this matter.
