Preliminary Plat and Preliminary Site Plan Revie.w: Ramsey Town Center 9th Addition May 27, 2005 Revised: June 24, 2005 Page 3 of 7 Street YAM 4 ends at the east plat line of the project. The location of the termination should not limit development options on the adjacent parceI. The end of Yam 1/Yam 4 is over 950 feet from the public street. A turn around is provided, however the extension to the east property line of the private street could lead to questions on maintenance responsibilities in future if a public street is platted east of the property line. 7, Open Space: The Town Center Development Review Guidelines encourage the integration of private courtyards and pocket parks within the TC~4 Neighborhood District. These small green areas provide important breathing space, contribute to stormwater management, and offer additional recreational amenities to serve the building tenants. The preliminary site plan complies with the development guidelines and provides green spaces for recreational and stormwater management purposes on each block. Grading and Drainage: Staff has received a grading .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 plan. The rock construction entrance on the Stormwater Pollution' Prevention Program (SW?PP) should be replaced with the requirement for daily sweeping of adjacent streets during active construction and as required by the city. The responsibility for the SWPPP on this site must be transferred to the new owner and contractor prior to commencing construction. 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 master stormwater plan. provides rate control for the entire Ramsey Town Center Project. The plan requires application of Best Management Practices (BIx[Ps) on each site to enhance stormwater quality. Developments approved to date have provided water quality treatment for 75%+ of the site. A portion of the site is directed to the infiltration basins prior to discharge off the site through the storm sewer system. The curb cuts to the infiltration basin mu~t be replaced with catch basins and flared end sections. A water quality treatment device must be installed at the point where the storm sewer system leaves the site. The percentage of the site draining to a BMP must be increased by rerouting water to the infiltration basins or by installing water quality treatment devices at the points where stormwater leaves the site. The grade of the street YAM 4 must be adjusted to provide a smooth transition to the property to the east. The development proposes discharging storm water from the east side of the site onto the adjacent property without rate control or treatment. This runoff should be collected and routed to the storm sewer system. The individual bituminous lift thicknesses must be specified. -290-
