Preliminary Plat and Preliminary Site Plan Review: Ram~ey Town Center 12tn Addition November 2_3, 2005 Page 3 of 7 10. Grading and Drainage: Staff has received a gra~ding and drainage plan for the development and has the following comments. Stormwater calculations must be submitted to the City and Lower Rum River Water Management Organization' for verification of conformance with the master drainage pl.an. The rock conslruction entrance on the Stormwater Pollution Prevention Program (SWPPP) should be replaced with the requirement for daily sweeping of adjacent streets during active, construction and as required by the city. ' A SWPPP is .required for this project. It must reference the SWPPP prepared for the Ramsey Town Center Project and provide for transfer of responsibility from RTC, LLC to this developer and contractor. The grading plan shows proposed retaining wails along the non-garage sides of the buildings. This will provide level areas adjacent to the buildings that can be used by the residents. There are areas where the grade slopes away from the building at a 4:1 slope down to the street. Raising the retaining wall height may provide more level area adjacent to the building. The plans show sidewalks from internal street to the trail along Bunker Lake Boulevard. These sidewalks all have steps. Please investigate providing one (t) accessible route with out steps between 147t" Terrace and Bunker Lake Boulevard. The proposed plan indicates some of the buildings will have up to 6 feet of foundation exposed below the first floor. Taller plantings must be provided in these areas as noted in the landscaping comments below. The "For Reference Only" note on all sheets should be moved to the right side of the sheet. Utilities: This subdivision will be served by sanitary sewer .and.city water services that will be extended into the development. The utilities are stubbed to the lots from the previous development. The invert elevations of the proposed building services must be shown on the plans. The vertical separatic}n between the water and sanitary sewer services'must be 18". Installation of one water service per building precludes conversion of the units to townhomes in the future. The main water meter must be in an accessible space, not in an individual unit. Water, Sanitary Sewer and Storm Sewer will need to be extended from south of Bunker Lake Boulevard to serve this project. The proposed points of location shown on' these plans assume construction of P,.TC 8th addition, additional plans will be required if RTC 8"~ addition is not constructed prior to this project. The utilities south of Bunker Lake Boulevard were included in the proposed assessments of the Master Development Agreement for Ramsey Town Center. Construction of the utilities must be coordinated with the city and conform to the assessment process. Assessments are addressed later in this letter. -416-
