The following documents were received: · Submitted Plans - Revive II Preliminary Plat 12-26-22.pdf · Stormwater Management Report - Revival II Storm Water Report 12-01-22.pdf We have the following comments with regards to stormwater management and engineering: General 1. Submit for and provide copies to the City of all required permits from regulatory agencies (MCES, Minnesota Pollution Control Agency, Minnesota Department of Health, NPDES, etc.) 2. Provide the access agreement with the adjacent property to the east to verify any language that may limit expansion due to traffic volumes and use of the shared access 3. Additional comments may be generated by PLSLWD’s review of the revised plans 4. Additional comments may be generated by Scott County’s review of the revised plans 5. Discuss access agreement for future lot through the west to connect to West Street. 6. Address all comments in the following memo and on the redline plan set and provide responses Site Plan/Grading Plan 1. Provide whether an agreement exists for ownership and maintenance of the existing retaining wall 2. Retaining walls greater than 4' shall require a plan prepared by a licensed engineer submitted for review and approval by the Building Official prior to permit issuance 3. Provide the first floor elevation of the adjacent building to the east to show minimum freeboard requirements are met 4. Provide the EOF of the filtration basin 5. Verify whether the potential draintile for the building will interact with the drainage of the infiltration basin where they share common walls/footings. 6. Show the limits of clearing and grading, including grading over the proposed storm sewer pipe to the west discharge point. 7. Provide emergency access turning movements with a fire truck that demonstrates that all building faces are within 150' of fire truck movements per 2020 MN State Fire Code Sec 503.1 Utility Plans 1. Provide ownership and maintenance agreements defining responsibilities for onsite stormwater, sanitary sewer and water utilities in the future a. Provide additional easement for access to the hydrants and water shutoff valves 2. Identify and label all utility crossings a. Insulate when separation is less than 36” between storm sewer and water service/main 3. Label existing utilities a. Existing watermain as 8” C900 4. Coordinate discharging to the County Pond by obtaining applicable permit and meeting County requirements 5. Install 4-foot sump manhole as the last structure which is road accessible prior to discharging into any waterbody (CBMH-103). 6. Modify the invert elevation of the pond inlet flared end section to match the outlet elevation of the pond. 7. Junction structures should be designed to limit hydraulic head increase by matching hydraulic flow lines (invert adjustments needed at CBMH 104). Stormwater Management 1. HydroCAD Model a. Modify the modeled pond outlet to match the OCS detail. i. Please provide the .hcp HydroCAD file so the orifice modeling can be reviewed. b. Submit an associated catch basin drainage area map. 2. Basin Design a. Install two or more underdrains for the basin. i. Noted that infiltration is now proposed instead of filtration but drain tile with a knife valve should be added to the basin in case the infiltration system clogs. ii. Underdrains must have a minimum slope of 0.5-percent. iii. Include at least 2 observations/cleanouts for each underdrain, one at the upstream end and one at the downstream end. b. Provide adequate pretreatment for all runoff prior to the infiltration basin. i. It is highly recommended that before entering an infiltration practice, stormwater should first enter a pretreatment practice sized to treat a minimum volume of 25 percent of the water quality volume. Due to site constraints, consideration of a SAFL Baffle or similar treatment device is recommended. c. Provide how maintenance access will be achieved for storm sewer structures in the infiltration basin. d. Install an observation well. e. A minimum of two infiltration tests shall be used to provide a base infiltration rate of surrounding soils. The infiltration tests shall be conducted at the location and elevation of the proposed infiltration system. f. A 66” minimum diameter structure is required for OCS with a weir wall. SWPPP 1. Add City detail plate #201 to the plans. Phone 952.447.9800 / Fax 952.447.4245 / www.cityofpriorlake.com Memo The Community Development Department has reviewed the Preliminary Plat and PUD plans for the subject project with a plan date of 12-22-22 and we have the following comments. General 1. Development Fees – The following development fees are to be collected prior to recording of any approved 2023 final plat application: Park Dedication ($9,000/net acre), Trunk Water ($4,180/net acre), Trunk Sanitary Sewer ($5,130/net acre), Trunk Storm Sewer ($9,390/net acre), and a 6% administrative fee and 8% construction observation fee based on the total estimated construction costs (which include any landscaping, public street/trail work and public utilities for this project). 2. Access Easement – Shall be recorded along with Final Plat at County following Final Plat approval. Site Plan 3. Elevation Plan – Submit an elevation plan with the breakdown/percentages of each exterior material so the City may review it with the Architectural Design Ordinance (see below). Grading Plan 4. Retaining walls – Any walls exceeding 4 feet in height will require a building permit application. Landscape Plan 5. Retaining wall trees – ensure that tree species above retaining wall will be suitable at mature width for placement between fencing and wall. 6. Tree placement – On landscape plan/details plan, indicate note that placement of all trees shall be a minimum of 5 feet from property lines. 7. Final tree locations – Tree locations may be subject to change depending on field construction of public/private utilities and maintenance access locations for ponding and utilities.
