Zoning File #1762 <br />October 16, 1992 <br />Page 2 <br />Section 10.207.A - Required construction. Every building <br />hereafter constructed shall be accessible to Fire Department <br />apparatus by way of access roadways with all-weather driving <br />surface of not less than 20' of unobstructed width, with <br />adequate roadway turning radius capable of supporting the <br />imposed loads of fire apparatus and having a minimum of 13' <br />6” of vertical clearance. Dead end Fire Department access <br />roads in excess of 150' long shall be provided with approved <br />provisions for the turning around of Fire Department <br />apparatus. <br />Additional provisions of that code (see Exhibit E) modify <br />this to some extent at the approval of the Fire Chief. Staff <br />will be contacting the Wayzata Fire Chief and will be discussing <br />the access issue with him to determine what standards may be <br />appropriate. <br />Septic/Driveway Conflicts <br />Of additional concern is the proximity of the proposed <br />driveway to a portion of the existing drainfield system for Lot <br />1, as well as a corner of the alternate site for Lot 2. Lot 2 <br />has primary and alternate sites tested which meet all <br />requirements except that one small corner of the alternate site <br />may end up within 10' of the proposed driveway depending on its <br />width and actual location. The grade is relatively level at this <br />location and only a small fraction of the alternate site would <br />ultimately be affected. This is a septic code variance which <br />staff would have no problem approving. <br />The existing drainfield is not failing and according io the <br />test information provided when it was installed in 3 987, it is <br />considered as a conforming system. However, the end of the last <br />trench will be 10' from the proposed lot line at the neck of Lot <br />2. Again this is not an issue except that staff questions <br />whether the driveway can be developed within its 15' corridor at <br />this location. <br />Driveway Development <br />No grading plan for the driveway has been submitted. <br />However, it is clear that where the new driveway extends westward <br />from the existing blacktop, the immediate drop in elevation will <br />require a significant width of fill to accomodate the 9' wide <br />driveway proposed, even more if additional width is needed for <br />f-;re access purposes. Working on the premise that we won't allow <br />driveway grading to occur within 5' of the south lot line of the <br />subdivision, how wide should the neck of Lot 2 become in order to <br />accomodate its driveway? If it needs to be 30' or more in width <br />at the east boundary where it abutts Outlot A, then Lot 1 would <br />no longer abut Outlot A, which would require a variance. As an <br />alternative, if Outlot A was extended, the question then becomes, <br />which boundary of Lot 3 is its front lot line, and does the <br />defined width meet the 200' requirement?
