The proposed action is for grading purposes only. The first addition of the final plat will create 55 lots, seven outlots, and right-of-way for public streets for the property. The final plat is tentatively scheduled for the July 24, 2019 City Council meeting. BACKGROUND On March 11, 2019, the Chanhassen City Council approved the following: • The Rezoning of 191 acres from Rural Residential District, RR, to Planned Unit Development - Residential, PUD-R; including the PUD ordinance 'Galpin Design Standards'; • The Wetland Alteration Permit of 1.28 acres of wetland impacts subject to conditions in the staff report; and • The Subdivision Preliminary Plat creating 169 lots, three outlots and dedication of public right-of-way as shown in plans prepared by Pioneer Engineering dated February 28, 2019, to be modified to match the site plan presented on March 11, 2019, with the reduction of four lots, subject to the following conditions: Stated on the conditions of approval section. On April 5, 2019, Lennar submitted a revised preliminary plat that was consistent with the conditions of approval of the March 11, 2019 City Council action. Those plans were modified on May 24, 2019. PROPOSED MOTION “The Chanhassen City Council approves a grading permit for the 1st Addition of The Park”. Approval requires a simple majority vote of City Council. Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 2 On May 24, 2019, Lennar submitted the final plat for the 1st Addition including a review of all of the conditions of the preliminary plat as well as the final plat. The approved PUD governs the standards for the development including a maximum of 31 Villa homes. REVISED PRELIMINARY SUBDIVISION REVIEW The applicant has revised the preliminary plat to include 169 lots. The final plat for the first phase is not being recommended for approval at this time. The 8-stall parking lot is being relocated to the south side of the street from its current location and the final plat needs to be revised. Street names will be reviewed with the final plat. Changes to the preliminary plat incorporated from the March 11, 2019 City Council meeting include: • Additional landscaping between the new homes on the Lucy Ridge Lane extended (cul-de- sac) • Additional buffer from Majestic Way • 8-stall parking lot was added • Removal of the gate house • The city will take ownership of the parkland, wetlands, stormwater ponds Below is the proposed phasing plan (four phases). Grading is proposed in three phases as shown in the plan below. Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 3 A sales trailer will be placed on the site. City staff has reviewed the location. The developer will have to follow city ordinance regarding sales trailers. The sales trailer will have to be removed when the model home has been built. Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 4 REVIEW CONDITIONS OF APPROVAL Parks & Recreation 1. Dedication of 100+/- acres of wooded open spaces and wetlands in the eastern half of the property to the City of Chanhassen for parkland in exchange for a housing density transfer and fulfillment of a nine +/- acre parkland dedication requirement.

Acknowledgement that the dedicated land may be developed at the city's discretion as parkland for public use and may include, but is not limited to trails, boardwalks, bridges, structures, and signage. Will occur with the Development Contract for the first phase. 3. The planning, engineering, grading, and placement of aggregate and bituminous base for construction of a 10-foot wide bituminous east/west trail connection between Galpin Boulevard and a location east of Street “D”, and in lieu of constructing a 10-foot wide bituminous trail adjacent to Galpin Boulevard between Street “E” and Street “A”, make a $120,000 (1,600 feet @ $75 per foot) contribution to the city’s Trail Fund. Will occur with the Development Contract for the first phase. 4. All trails shall meet all city standards for trail construction. Will occur with the Development Contract for the first phase. 5. The east/west trail shall maintain a minimum 10-foot setback from outside edges of trail to private property and be designed to minimize encroachment of wetland buffers. Will occur with the Development Contract for the first phase. 6. The east/west trail crossing of Street “A” shall be relocated from a midblock crossing as shown to the intersection of Street “A” and Street “D”. Will occur with the Development Contract for the first phase. 7. The east/west trail shall be designed and constructed so as not to require retaining walls. Will occur with the Development Contract for the first phase. 8. The entirety of the east/west trail and associated buffers shall be constructed within the dedicated public outlots. Will occur with the Development Contract for the first phase. 9. The planning, engineering and construction of the 10-foot wide bituminous trails connecting both Street “Z” and Topaz Drive/Ridge Lane to the planned trail at the western edge of Lake Lucy including trail easements. Will occur with the Development Contract for the first phase. Planning 1. All 191 acres must be included in the PUD. Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 5 2. All lots and homes must be developed consistent with the standards in the Compliance Table. RIGHT-OF-WAY AND EASEMENTS There is an existing 20-foot wide Metropolitan Council Environmental Services (MCES) sewer and utility easement located on the property as illustrated on the submitted revised preliminary plat. Generally, the easement traverses from the northwest corner of the property to the southeast corner of the property, bisecting the site diagonally. The applicant is proposing to impact the easement at two locations. The first location is within the northwest corner of the site where grading and construction of “Della Drive” and Basin 200 are proposed. The second location is to the east of “Dove Court” where grading is proposed behind Lots 119-120. The MCES has been supplied the applicant’s site plans, and all comments and conditions set forth by the MCES shall be addressed by the applicant. An agreement to construct any of the proposed improvements over the MCES’s easement must be executed and supplied to the city for review prior to the issuance of grading permits. As no grading or construction is proposed in these easements for The Park 1st Addition, no agreement will be required at this time. The applicant is proposing standard drainage and utility easements (D&U’s) around the majority of the lots on the provided preliminary plat. Additional 20-foot wide D&U’s have been provided within Lots 139-153 abutting “Della Drive and Lots 166-169 abutting Topaz Drive. These 20- foot wide D&U’s are provided for stormwater collection and conveyance systems located in backyards that fall outside the standard D&U’s. Furthermore, 30-foot wide D&U’s between Lots 128-129 abutting “Lewis Lane” and Lots 22-23 abutting “Paisley Parkway” have been proposed to provide access to proposed utilities and the north and south side of Basin 300. Thirty-foot (30-foot) wide D&U’s between Lots 151-152 abutting “Della Drive” have been proposed to provide access to a water main extension to Ruby Lane. Right-of-way dedication will be required along the east side of Galpin Boulevard per Carver County’s review and comments (see “Carver County Development / Access Review Comments” attached), the Highway 117 Corridor Study, and the typical roadway sections identified in the County’s Draft 2040 Comprehensive Plan. The Corridor Study identifies specific right-of-way needs and the plat will be required to follow and be consistent with the preferred roadway alternative. The right-of-way shall tie into the existing highway right of way north and south of the proposed development. The final plat proposal shall be reviewed and approved as to form and content by the county surveyor and city. After review by the city of the proposed final plat for The Park 1st Addition, adequate right-of-way has been dedicated. Currently, there exists overhead utilities within the right-of-way abutting the development on the east side of Galpin Boulevard. The applicant will be required to underground all overhead utilities from the southern property line to the northern property line. Underground utilities reduce the risk of accidents, such as vehicles colliding with poles and service impacts such as storms knocking down limbs on lines. It also improves the overall esthetics of roadway corridors and neighborhoods, which improves and promotes livability. Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 6 EXISTING CONDITIONS SURVEY Well and Septic Water wells and septic fields have been identified on the existing conditions survey. The abandonment of all existing wells shall be in accordance with the Minnesota Department of Health’s review and regulations, and the abandonment of all existing septic systems shall be in accordance with the Minnesota Pollution Control Agency’s review and regulations. All required permits from the appropriate regulatory agencies shall be obtained prior to the commencement of any abandonment(s). GRADING The applicant is proposing to construct eight stormwater basins (Basins 100, 200, 300, 400, 500, 600, 800, 900) within and around the development. Through the preliminary grading plan and grading details, drainage from individual lots will be routed away from buildings into a series of catch basins and reinforced concrete pipe located within drainage and utility easements in backyards. Drainage from proposed public streets will be collected through catch basins located next to curbs, and routed to stormwater basins within and around the site. The applicant has provided an overall grading plan and the phased grading schedule for the entire subdivision as well as a grading plan for The Park 1st Addition. Both plans generally conform to city ordinances and standards for grading, with minor changes required. The applicant shall meet all the conditions enumerated with the grading permit prior to commencement of grading operations. There are proposed driveways that approach the maximum 10% grade (e.g. Lot 152 abutting “Della Drive” is at 9.9% grade) and one street that reaches the maximum 7% grade (“Paisley Parkway” near station 1+45) allowed by city ordinance. Staff recommends limiting maximum grades in order to achieve a higher level of constructability. Any constructed street or driveway that exceeds maximum allowable grades upon final inspection will be required to be removed and replaced. There are two bluffs within the site. One bluff is located west of Lots 106-164 abutting Lucy Ridge Lane, and a second bluff is located south of Lots 148-149 abutting “Della Drive”. The grading plans indicate the locations and extent of the bluffs and their appropriate buffers and setbacks. All grading operations have been proposed to be outside the bluff impact zones. Currently, while the grading plan shows a majority of stormwater being routed to appropriate treatment methods (BMPs), some lots (e.g. Lots 118-122 abutting “Dove Court) do not appear to have a method of conveying untreated stormwater runoff to BMPs. As by city ordinances, no untreated stormwater shall be routed to wetlands prior to treatment. While the proposed public trail system meets the Americans with Disabilities Act Accessibility Guidelines (ADAAG) for maximum running slope of trail segments (no more than 30% of the total trail length to exceed a 1:12 slope), staff recommends the installation of a level resting pad Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 7 over continuous grades over 8%. This recommendation is based on the intent of ADAAG which is to provide access to the greatest extent possible. The plat’s final grading plans, ponds, and right-of-way along Galpin Boulevard shall be reviewed and approved by the county and the city to show how they conform to the potential future Galpin Boulevard reconstruction. A cross reference of grading plans, profiles, and respective cross sections should be provided at key locations such as intersections, ponds, or other special features for review by the county and city prior to acceptance. SHORELAND MANAGEMENT This phase in not in the shoreland management area. RETAINING WALLS No retaining walls are being proposed with the development. STREETS The applicant is proposing construction of eight new streets (Della Drive, Raspberry Road, Paisley Parkway, Alphabet Street, Dove Court, Lewis Lane, Nelson Path, and Rogers Circle) and the extension of one existing street (Lucy Ridge Lane) that shall be owned and maintained by the city after acceptance of the public improvements by the City Council. All newly constructed street sections shall be designed to meet the current standard specifications and detail plates for residential streets. These new streets and extensions will result in eight cul-de-sacs with seven of the eight proposed cul-de-sacs meeting current city code and standard specifications. “Della Drive”, a newly constructed street and cul-de-sac in the northern section of the development, exceeds the maximum length for a cul-de-sac per city ordinance; however, it was approved in the preliminary plat by City Council. Engineering recommended approval of the cul-de-sac as the topography would require substantial grading and the loss of significant trees that would alter the physical character of the property and surrounding parcels (Ordinance 18.57.k.2). Access to “Della Drive” is from Galpin Boulevard, a collector road. There is an existing driveway 30 feet south of “Della Drive” providing access to Parcel 250100400. This spacing does not meet MnDOT Access Management Guidelines or Carver County’s requirements for access points had off collector roads. The parcel’s access from Galpin Boulevard will be abandoned and realigned to tie into “Della Drive” as the future Galpin Boulevard Redevelopment project approaches. Additionally, a water stub for future connection shall be installed to serve the property. The city has had discussions with the resident of this property and has obtained verbal agreeance of such a realignment and future water service connection. The applicant has supplied a geotechnical evaluation report that was completed by Braun Intertec Corporation on June 29, 2018. The report discussed and explored design and construction recommendations for roadway sections, amongst other topics. The updated plans and updated geotechnical evaluations provided since the original preliminary plat submittal show adequate Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 8 boring information and provide sufficient guidance on the construction of the public streets. However, it will be required of the developer to have a geotechnical engineer onsite during grading operations. If groundwater is encountered during grading, grades shall be adjusted to maintain a 3-foot separation from the bottom floor elevation of proposed buildings. Subsequent changes to grades shall be submitted to the city for review and approval. Sidewalks and pedestrian access points have been proposed on a majority of the streets throughout the development. However, Lucy Ridge Lane will require an extension of sidewalk to provide access within the cul-de-sac. Sidewalks shall be constructed in accordance with city standard specifications and detail plates. All curb ramps shall be constructed to meet ADA standards and the city’s detail plates. The sidewalk located at the intersection of Galpin Boulevard and “Raspberry Road” terminates with no proposed intersection improvements to access the existing trail system on the west side. The developer will be required to extend connectivity by providing access from the newly constructed east side to the existing west side of Galpin Boulevard by utilizing approved MUTCD practices for pedestrian crosswalk and intersection improvements. Street lights have been proposed throughout the development. Street lights will be required at all intersections and at the end of each cul-de-sac. The developer will need to work with Xcel Energy for the installation of city-approved street lights. A $300 fee shall be collected with the development contract for each street light for the purpose of electricity costs for the first year of operation. WATER The applicant is proposing to construct 8” PVC C900 water main throughout the development that shall be owned and maintained by the city after acceptance of the public improvements by the City Council. The development is located between two pressure zones in the city; a high pressure zone and a low pressure zone. To the west in the Longacres neighborhood is a high pressure zone. To the north and south in the Ashling Meadows and Royal Oak Estates neighborhoods, respectively, are low pressure zones. The city has modeled the impact of the development based on the proposed usage. It was found that in order to provide adequate pressures and fire flows, water mains shall be tied into the high pressure zone located on Galpin Boulevard. This will result in some areas of the development experiencing pressures above 90 PSI. Therefore, a portion of the homes will likely require individual pressure reducing valves. The developer will need to work with the Building Department and Public Works Utility Department to determine which homes will require pressure reducing valves. In the northwest area of the development where Lucy Ridge Lane will be extended, the developer is proposing to tie into the low pressure water system via the existing 8” PVC water mains. Engineering does not anticipate any extraordinary impacts to the water system’s pressure or fire flow for the proposed 15 connections. Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 9 “Della Drive” will be tied into the high zone water system via the existing water main off Galpin Boulevard. “Della Drive” is currently proposed as a cul-de-sac, and the applicant was proposing the creation of a dead end system. Public Works required the applicant to tie in the proposed water main on “Della Drive” to the existing water main stub located off Ruby Lane, to the north, which is now being proposed with the updated preliminary plans. Because “Della Drive” will be within the high pressure zone, and the north tie-in location on Ruby Lane (Ashling Meadows neighborhood) is within the low pressure zone, updated construction plans call out a gate valve to be installed where the system ties in. This gate valve will remain closed in order to separate the two zones, and will be opened by city forces during any maintenance or repair work in order to “back feed” the system, as necessary. The majority of the water main to be installed is within the central and southern portion of the development (Lots 1-138). The applicant is proposing to create a looped water system which meets city best management practices for water utilities. Looped systems improve reliability by feeding water from two directions rather than one, which subsequently allows service to continue during an event that may otherwise cause disruption to water service. Water main connections will be tied into the high zone water system off Galpin Boulevard. The applicant shall verify the location of the connections on the construction plans. All water main taps, connections, and required water main testing shall be witnessed by the city. A pre-construction meeting prior to the commencement of any work shall be scheduled by the developer’s contractor with the city. Additionally, all underground utilities on the east side of Galpin Boulevard have not been located and illustrated on the plans, for example, the city’s raw water main that feeds the west treatment plant. This area on the east side of Galpin Boulevard is where water and sanitary sewer will cross before entering the development. Thus, prior to the issuance of public utility construction, all underground utilities in this area shall be surveyed and illustrated in the profile sheets in order to identify any conflicts. From the proposed preliminary water plans, there are multiple areas where water main and sanitary sewer mains will cross. All crossings of water and sewer utility mains are required to have 18” of vertical separation and 10’ of horizontal separation, measured from the edge of pipe. Where water mains cross sanitary sewer mains do not meet vertical or horizontal separation requirements, the sanitary sewer shall be constructed of C900 water main material. All crossings shall be required that the sanitary sewer pipe length shall be centered over the water main crossing. The preliminary plans delineate areas where water main will run closely adjacent to, or under, stormwater catch basins. This may cause a potential for freezing of the water main at these locations due to inadequate ground cover from catch basin bottoms (sumps) to the water main. Water mains shall be constructed at 7.5’ below grade, or insulated, and constructed in conformance with the city’s standard specifications and detail plates. Plan and profile sheets provided with the construction drawings of the water main shall include the location and depth of catch basins and their sumps for review and approval prior to issuance of building permits. The applicant shall ensure all fire hydrant spacing meets fire codes and are subject to the review and approval of the Fire Department. Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 10 SANITARY SEWER The applicant is proposing to construct 8” PVC sanitary sewer main throughout the development that shall be owned and maintained by the city after acceptance of the public improvements by the City Council. The entire sanitary sewer system will operate as a gravity system and connects to existing sanitary sewer mains at three locations; Lucy Ridge Lane, a direct connection to the MCES sanitary sewer trunk line on “Della Drive” and at the Majestic Way extension off “Paisley Parkway” through a utility easement. As proposed, the connection to the MCES sanitary sewer trunk line from “Della Drive” and its subsequent manhole are not within the roadway, down steep grades, and abutting Basin 200. The applicant shall resubmit construction drawings with this phase of the development to provide the access manhole and tie-in on and within “Della Drive”. All conditions set forth by MCES shall be addressed by the applicant for the required access manhole and direct connection to their trunk line, and all permits required shall be obtained prior to the commencement of construction. The preliminary plans submitted utilize a nomenclature for identifying proposed manholes that differs from the city’s. On all future submittals, the applicant shall ensure the city’s manhole naming conventions are incorporated within the plans. The city has provided a list of appropriate manhole identifiers, as well as fire hydrant identifiers. This will ensure an efficient transition of the newly constructed public improvements into the city’s asset management system for sanitary sewer manholes and fire hydrants. Profile sheets for all public utilities, including sanitary sewer, shall be required for review and approval by the city prior to issuance of building permits for all phases. Based on the provided profile and plan sheets for the 1st Addition, the applicant is proposing sanitary sewer that reaches a maximum depth of over 26’. PVC sanitary sewer pipes that have a burial depth of 0-16 feet are required to be class SDR 35, burial depths of 16-26 feet requires class SDR 26, and burial depths of greater than 26 feet requires class C900. The applicant has shown that the proposed sanitary sewer pipes falling within these burial depths have the appropriate class of PVC. STORMWATER MANAGEMENT General 1. The applicant has delineated all wetlands on the property and agencies have approved the boundaries and type. 2. Wetland permitting is required due to the proximity and proposed impacts to wetlands onsite. Grading permits will not be issued until approved wetland permits have been received. See “Wetland Alteration” of this staff report for more information. 3. An NPDES permit has been obtained by the application. An updated stormwater pollution prevention plan (SWPPP) will be required prior to the start of grading. 4. An operations and maintenance plan for the proposed stormwater management system will be required. Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 11 5. All comments and conditions set forth by the Riley Purgatory Bluff Creek Watershed District shall be addressed by the applicant. Preliminary Plans Infiltration test results will be required in the location of all proposed infiltration benches and infiltration basins. Infiltration test results have not been submitted in the location of proposed Basin 100. If filtration is to be used, the applicant will need to provide a specification for amended soils. Furthermore, the slope of the outlet pipe from Wetland 12 should be updated to match what is shown in the preliminary utility plans. HydroCAD Model There were numerous inconsistencies between what is shown in the plans and what was being modeled in HydroCAD and P8. The only inconsistency remaining to update is the weir in OCS 400B should be changed in HydroCAD from a four-foot weir to a five-foot weir. Also, the 15” outlet pipe from CB 490 should be included in the HydroCAD model to ensure the pipe does not restrict flow and back up water at the low point. The 19” horizontal orifice should be routed to the 15” pipe. P8 Model For the basins where filtration is proposed, the infiltration in P8 should be routed to the downstream waterbody instead of out of the system for accuracy. It appears the proposed stormwater system will still meet water quality requirements after the updates. WETLAND ALTERATION The plan set shows intent to impact several wetlands on site. A Wetland Replacement Plan application was submitted to the city and reviewed per the WCA. A Notice of Decision and Approval for the Wetland Replacement Plan was sent on June 6, 2019. Wetland mitigation was approved through the purchase of wetland credits with wetlands being replaced at a ratio of 2:1. Wetland 14, proposed to be impacted during The Park 1st Addition, will require a United States Army Corps of Engineering (USACE) permit as it was determined to be a USACE jurisdictional wetland. Wetland buffers using buffer averaging has been applied to the project. Wetland buffers and buffer setbacks pursuant to section 20-411 and consistent with the preliminary plat must be memorialized with a recorded wetland buffer agreement filed with the county recorder’s office. EROSION PREVENTION AND SEDIMENT CONTROL The proposed development will exceed one (1) 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 Todd Gerhardt The Park 1st Addition Final Plat July 8, 2019 Page 12 Construction Permit). The applicant has prepared and submitted a Surface Water Pollution Prevention Plan (SWPPP) to the city for review and has obtained an NPDES Construction Permit for the 1st Addition. No earth disturbing activities may occur until a SWPPP is approved by the City. This SWPPP shall be a standalone document consistent with the NPDES Construction Permit and shall contain all required elements as listed in Parts 1.1 through 25.37 of the permit. Financial Assurance To guarantee compliance with the grading plan, and related remedial work, a cash escrow or letter of credit, satisfactory to the city, shall be furnished to the city before a grading permit is issued for The Park 1st Addition. The escrow amount shall be $308,265.00, which is 110% of the estimated erosion control and pond excavation costs for The Park 1st Addition. The city may use the escrow or draw upon the letter of credit to reimburse the city for any labor or material costs it incurs in securing compliance with the plan or in implementing the plan. The city shall endeavor to give notice to the owner or developer before proceeding, but such notice shall not be required in an emergency as determined by the city. The assurance shall be maintained until final stabilization and removal of erosion and sediment controls and acceptance of dedicated public streets and public utilities. STORMWATER UTILITY CONNECTION CHARGES Section 4-30 of city code sets out the fees associated with surface water management. A water quality and water quantity fee are collected with a subdivision.
