Sylvia Frolik April 17, t997 page two study. Such an access would better merit the costly highway improvements that are needed, and would also ease the future development of neighboring properties, solving their access problems before they become problems. We appreciate the dedication of fight-of-way for a frontage road, however, we do not recommend that a frontage road connect to the proposed Apple Ridge street in such a narrow strip of land. The frontage road/Apple Ridge street intersection would be so close to the Apple Ridge street/TH 47 intersection that there would be no room for vehicle queuing between the intersections. Such close spacing creates inadequate driver reaction distance, particularly since cars leaving and entering the highway often do so at high speeds. This situation of'ten leads to driver confusion and accidents. The frontage road should connect to the Apple Ridge street at least as far away from TH 47 as the first cul-de-sac west of the highway. We recommend that the plat set aside right-of-way for a "backage" road rather than a frontage road-- in other words, an access road set back from the highway by the depth of one lot. A "backage" road may be a more feasible solution for the lots north of Apple Ridge than a frontage road, as well as providing safer traffic circulation within Apple Ridge itself. A Mn/DOT drainage permit is required for Apple Ridge. Stormwater from the development should not be drained toward the highway. There is no ditch along TH 47 through which to drain the development's water, and the DNR wetland to which the water would flow has no apparent outlet. The development should have water quality ponds, as required by federal law, and could use the native soil's permeability to reduce runoff.to a minimum. Questions about our drainage concerns may be directed to Bonnie Peterson of our Water Resources Section at 797-3088.. Questions about the permit process may be directed to Bill Warden, as noted above. Any use of or work within TH 47 right-of-way, temporary or permanent, will also require a permit. The type of permit needed depends on the nature of the proposed work. As noted above, Bill Warden may be contacted for further information. As I will b~ leaving Mn/DOT in about a month, please be sure to direct future plats and site plans to our Local Government Liaison Supervisor, Sherry Narusiewicz, at the above address. If you have any questions about this plat review, please contact me at 582-1383. Sincerely, Elizabeth Malaby Transportation Planner/Local Government Liaison c: Skip Anderson, A~noka Co.
