Zoning File #1762 October 16, 1992 Page 2 Section 10.207,A - Required construction. Every building hereafter constructed shall be accessible to Fire Department apparatus by way of access roadways with all-weather driving surface of not less than 20* cf unobstructed width, with adequate roadway turning radius capable of supporting the imposed loads of fire apparatus and having a minimum of 13* 6" of vertical clearance. Dead end Fire Department access roads in excess of 150* long shall be provided with approved provisions for the turning around of Fire Department apparatus. Additional provisions of that code (see Exhibit E) modify this to some extent at the approval of the Fire Chief. Staff will be contacting the Wayzata Fire Chief and will be discussing the access issue with him to determine what standards may be appropriate. Septic/Driveway Conflicts Of additional concern is the proximity of the proposed driveway to a portion of the existing drainfield system for Lot 1, as well as a corner of the alternate site for Lot 2. Lot 2 has primary and alternate sites tested which meet all requirements except that one small corner of the alternate site may end up within 10* of the proposed driveway depending on its width and actual location. The grade is relatively level at this location and only a small fraction of the alternate site would ultimately be affected. This is a septic code variance which staff would have no problem approving. The existing drainfield is not failing and according to the test information provided when it was installed in 1987, it is considered as a conforming system. However, the end of the last trench will be 10* from the proposed lot line at the neck of Lot 2. Again this is not an issue except that staff questions whether the driveway can be developed within its 15* corridor at this location. Driveway Development No grading plan for the driveway has been submitted. However, it is clear that where the new driveway extends westward from the existing blacktop, the immediate drop in elevation will require a significant width of fill to accomodate the 9* wide driveway proposed, even more if additional width is needed for fire access purposes. Working on the premise that we won't allow driveway grading to occur within 5' of the south lot line of the subdivision, how wide should the neck of Lot 2 become in order to accomodate its driveway? If it needs to be 30* or more in width at the cast boundary where it abutts Out lot A, then Lot 1 would no longer abut Outlet A, which would require a variance. As an alternative, if Outlet A was extended, the question then becomes, which boundary of Lot 1 is its front lot line, and does the defined width meet the 200* requirement? timA
