Box 66 <br />Crystal Bay, Minnesota 55323 <br />VTuLAGZ Cr CPCNO <br />Subject: The Farm at Long Lake <br />Dear Hank: <br />We have reviewed a revised preliminary plat on the subject <br />project. The preliminary plat included drainaae easements, a <br />dedication of 33' of right-of-way along the length of Dakota <br />Avenue, proposed drainage patterns, the locations of drainage <br />structures and a centerline road profile. <br />With respect to the submittals, we have the following comments: <br />1. Some relatively steep road grades are provided (in excess <br />of 7%) on both West Farm Road and North Farm Road. One could <br />expect considerable washing if a gravel road is proposed. We <br />would not recommend slopes over 6% on City streets, but our <br />understanding is that the proposed streets will be private. The <br />developer should strongly consider blacktopping, but we will not <br />require it at this time since the streets will be private. <br />However, we do recommend that the drainage ditches adjacent to <br />the street be sodded and check dams be provided to control erosion <br />along the roadway. <br />s <br />2. We have reviewed the Hennepin County soil maps prepared <br />for the subdivision. Although some slopes are excessive (in exc <br />of 12%) and some Glencoe and Hamel soils are present, it appears <br />that each lot has ample suitable soil for an on-site treatment systems. <br />3. Hennepin County lias expressed some concern relative to the <br />location of the intersection of North Farm Road and County Road 6. <br />The Council's approval of the preliminary subdivision should be <br />contingent on Hennepin County's approval of the intersection. <br />12805 OLSON MEMORIAL HIGHWAY.
