Zoning File #2279 August 14, 1997 Page 5 de-sac. Enough area has been left to the west of wetland Basin E to accommodate the driveway and a 26 ’ setback from that basin for the driveway. The driveway would have to be looped near the proposed residence in order to accommodate emergency vehicle ingress/'egress. This lot has two drainfield sites proposed between the house and the wetland basin, again requiring a \ ariance for setback of the drainfield from the wetland, and again as drawn not matching the site evaluation report. This variance is more difficult to justify than the V ariance for Lot 1, because Basin E is an open w ater basin, of substantial area, proposed to be a NURP pond, and clearly drains directly towards Basin E. Applicants note it is not possible to locate the drainfields in Lot 2 any further from Basin E without encroaching the proposed house pad. Lot 3 - Lot 3 contains the e.xisting house which is served by an existing septic system to the south of it, with alternate drainfield site directly west. This alternate site again does not meet the 75' setback from Basin E. and does not match the site evaluators report. Lot 3 is currently served by an existing loop driv eway that extends to Lyman Avenue east of the applicants' property. This driveway exists on an easement. The applicants have shown on the grading plan an optional driveway within the property and parallel the east lot line, with a new access point abutting Outlot A. Lot 3 abuts Basin D, and there arc no expected impacts or encroachments on Basin D. Lot 4 - Lot 4 can be characterized as a knob located about 30' above Lyman Avenue, with especially steep slopes to the north. The proposed house site is at the northeast quadrant of the lot, and the grading plan indicates a proposed narrow driveway in the easterly comer of the property. The drivewav as shown is only 6' wide, and does not relate to the actual septic site per tlie site evaluators report. Staff also questions whether the location as proposed in the grading plan has satisfactory site distance given the sharp curve to the south. While a vehicle leaving Lot 4's driveway would not be crossing traffic, the narrowness of the road suggests that any vehicles coming eastward around the curve could have a conflict with any car leaving Lot 4. Also, the lack of a secondary drainfield site, and the uncertainty of sewer being provided to this property, suggests that Lot 4 simply is not a buildable lot and should not be approved. Outlot A - WTiile Outlot A follows the existing location of the private road/driveway system knowTi as Lyman Avenue, it does not purport to make any changes or improvements to that road, other than to provide a portion of roadway corridor for its continued existence. Outlot B - Outlot B is proposed to contain a paved private road and cul-de-sac, with a retaining wall uphill to the east and down hill to the west. The retaining wall will accommodate the necessar>' drainage swales to allow drainage to the NURP pond adjacent to Basin E. The retaining wall will limit access to Lot 4 from Outlot B. This proposed road is very near an adjacent neighboring residence, and at the 24'paved width standard plus an
