1 Ramsey Town Center 1? - Anoka County Medical Examiner FaciZhy _ Final Plans August 8, 2007 Page S of 6 The Ramsey Town Center Development utilizes regional stormwater ponds for rate control and water quality treatment. Each individual site needs to provide additional water quality treatment through the use of rain gardens or water quality treatment structures. The plan is proposing pervious pavers for the drives leading to the garage doors and an infiltration basin in the north east corner of the site. These practices serve 23% of the site. We have required recent developments to provide closer to 50% coverage with alternative treatment devices. The infiltration basin is overlapped by an optional building expansion which would require removing the basin when the expansion is constructed. Additional devices must be provided. The plans show storm sewer extending east across the adjacent parcel to carry stormwater to the regional system. The location of the storm sewer should be selected to m inimiz e the impact to future development plans for this parcel. The pipes extending across the proposed outlot must be covered with drainage and utility easements. The City takes ownership of storm sewer pipes serving more than one parcel such as these pipes. The connection to the existing line in Peridot Street must be from MH 1101 to the closest structure. We will not accept parallel storm sewer lines in Peridot Street. The storm sewer stub from CBMH 1109 must be extended so that the fixture connection can be made with out disturbing the curb or pavement. The detail sheet must be updated with the current City Details. Street and Binding Access: The site will have one standard access and one right -out only access from Rhinestone Street. The south access will accommodate two -way traffic to and from the site. There is one exit -only access onto Rhinestone Street from the garage. City Staff was originally concerned that this exit would conflict with the two -way access to the south of it. The sole purpose of this exit is to accommodate hearses leaving the garage area, which is not an activity of high frequency. Therefore, . City Staff determined that a right -out only onto Rhinestone is acceptable in this case. The southerly access does comply with the spacing requirements from the intersection of Civic Center Drive and Rhinestone Street. Traffic Generation: As part of the Town Center AUAR, a detailed traffic analysis was completed that anticipated the type and size of development shown on the plat. The proposed development is consistent with the traffic modeling system used as part of the AUAR analysis. Regional road improvements to facilitate the whole Ramsey Town Center development have been agreed upon and have already begun construction. This proposed development does not generate more traffic than was anticipated. Utilities: Utility stubs for water, sanitary sewer and storm sewer have been extended to the property line from the adjacent streets. The watermains must be covered with drainage and utility easements. —120-
