Preliminary Plat and Preliminary Site Plan Review: Symphony At TOVlIfi Center April 26, 2007, Revised May 17,2007 Page 4 of7 A SWPPP is required for this project. It must reference the SWPPP prepared for the Ramsey Tovvn Center Project and provide for transfer of responsibility from RTC, LLC to this developer and contractor. The master stormwater plan provides rate control for the entire Ramsey Town Center Project. The plan requires application of Best Management Practices (B.MPs) on each site to enhance stormwater quality. The infiltration basins shown on the plans will provide water quality treatment, however it appears only 30% of the site drains to these devices, the remainder of the water discharges directly to the regional system. The percentage of the site draining to a B:MP must be increased by rerouting water to the infiltration basins or by installing water quality treatment devices at each point where stoIDlwater leaves the site. The maximum cross slope on driveways must be adjusted from 3% to 2.5%. Sapphire Way must be revised to have a crown from 146tb Avenue to 145th Place as well as all of 146th Lane. Universal cross slope will be permitted on private drives between buildings, not on the collector drives accessing the public streets. Silt fence must be shown on the enlarged grading plans. Curb cuts draining to the Bioretention Facility must be replaced. with a structure and outlet pipe. The local soils are erode easily and curb cuts like these require constant maintenance. 9. Utilities: This subdivision will be served by sanitary sewer and city water services that will be extended into the development. The following specific comments must be addressed: Ductile iron pipe 6" and smaller must be Class .53, 8" and larger is Class 52. Provide specifications for the Ecostorm 1.5 device. Provide Ecostorm devices at STMH 101 and CRMH 117. The applicable city details must be added to the sheets. Contact the Engineering department for the latest details. 10. Tree Preservation.

City policy requires installation of sidewalks on both sides of the street for State, County and MSA roads, and along one side of the street for local through streets. No sidewalks are required on cul-de-sacs. Accordingly, the revised plans continue to provide a sidewalk arOillld the perimeter of Block I and 2, either as an interior improvement within the plat or as a part of the Town Center trail system. Additionally, the site plan proposes connections between the interior sidewalks and the Tovvn Center trail system. Block 2 needs a sidewalk connection to the sidewalk on East Ramsey Parkway at the south end of Rhinestone Way. 12.
