Final ]'k~t and Final 5'itc Plan Review: Rarnsey Town Center 9th ~4ddition .7~dy 22, 2005 Pc~ge 3 of 6 installation, as a Stage I Improvement in the Development Contract. The Homeowners Association will be responsible for the ongoing maintenance costs associated with the signs. Willemite Way/148th Terrace ends at the east plat line of the project. The location of the tcrn~ination should not limit development options on the adjacent parcel. The end of 148th Terrace/Willemite Way 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 ifa public street is platted east of the property line. 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 final site plan complies with the development guidelines and provides green spaces for recreational and stonnwater 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 orghnization for verification of conformance with the master drainage plan. 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 Tovm 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 (BMPs) 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. 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 poir~ts where stormwater leaves the site. Drainage from the back yards on the east and west sides of the devclopment is directed onto adjacent private property or the proposed park with out attenuation or treatment. This must be addressed in the revised plans. Stormwater Analysis: The latest SWMM model shows an increase of 3.0 acre feet in the West Park pond. The pipe from the 8th, 9th, and l0th Additions is upsized to pass the 100-year event fi'om these projects to the West Park pond. The change in pond level is approximately 0.1 feet. The storm sewer system should be revised to direct discharge to the existing wctlaud in North Park to provide recharge of the wetland. 10. Utilities: This subdivision will be served by sanitary sewer and city water services that will be extended into the development. The following sheet specific comments must be addressed:
