Review Letter - Brandseth January 30, 1996 Page 2 of 3 corridor. The preliminary plat shows an additional dedication along T.H. 4/47 of 17 feet, bringing the total right-of-way width to 50 feet. Because of the potential for future improvements .to the intersection of T.H. #47 and 153rd, this dedication needs to be 60 feet and therefore, an additional 10 feet of right-of-way is requested. Transportation Impacts: On November 20, 1995, the Ramsey City Council approved the implementation of a Transportation Impact Fee at a rate not to exceed $500 per lot. It is expected that if the fee is enacted by April 15, 1996, Brandseth will be subject to said fee. Wetlands: There are no protected wetlands nor wetlands which appear on the national wetland inventory located within this parcel. The applicant is responsible for complying with the Wetland Conservation Act. If any areas within the plat meet the wetland def'mition, they are protected by the Act. Drainage: A revised Drainage Plan prepared by Ross Abel and dated January 19, 1996, has been reviewed and is generally acceptable. Ali roadways within the plat are drained overland to the intersection of Germanium Street with 152nd Avenue and 152nd Lane. A storm sewer within Germanium conveys stormwater to a point approximately 200 feet south of 153rd Avenue and then coveys the stormwater eastward to a detention pond proposed to be constructed within a natural low area south of I53rd Avenue located on the future commercial outlot. A 12 inch outlet from this sedimentation pond is proposed to run along the west right-of- way of T.H. #47 and discharge into the roadside ditch south of 152nd Avenue. From there, the ditch would convey the flow into DNR protected wetland #658. An outlet to the Rum River for this wetland and wetland //657 which is on the east side of T.H.//47 is proposed for construction during the summer of 1996. The backyards of the lots west of Germanium are proposed to drain northward overland toward the natural low point near the UPA substation. Staff recommends that a storm pipe be extended eastward from Germanium Street at a point south of the substation. This storm pipe will allow for the drainage of City property to the west and will also intercept drainage from six of the ten rear yards in this block. Rear yards from ten lots south of 152nd Avenue also follow the natural topography and drain onto the adjacent property to the south. Ali other rear yards drain to the interior of the subdivision. The volume of rear yard drainage from the plat onto adjacent parcels represents a reduction from the existing conditions due to a reduction in contributing drainage area. Utilities: This subdivision will be serviced with municipal sewer and water utilities. It is anticipated that sewer and water will be extended to the plat through the service road and Kempf property along the west side of T.H. f47. However, alternative extension routes do exist. A twelve inch trunk watermain along 153rd Avenue and Germanium Street will be installed as part of the water distribution system.
