3A This would entail the combination of several lots along the eastern border and a lot-by-lot allocation of impervious surface. The Planning Staff and developer have calculated impervious surface needs for the development (including roads) and have determined that if joint driveways are utilized, and homes are built relatively close to the 40 foot landscape setback, the 6% impervious surface limit is feasible. The State mandate allows for local approval of minor variances to numerical standards such as lot size and impervious surface limits. The model ordinance prepared by DEM suggests that a 'Minor Variance' be defined as a change of 10% or less in a numerical standard. This provision is included in the proposed watershed protection standards. The Planning Staff recommends that the applicant be allowed (with approval of the Planning Director) to utilize an additional 0. 6% impervious surface if driveways and/or houses cannot be sited in a manner to fully comply with the 6% . The Planning Board will consider the proposed changes at its meeting on September 20. The Planning Staff will report the Planning Board recommendation to the Board of Commissioners on September 21. RECOMMENDATION: The Administration recommends approval of the proposed changes to the Governor ' s Grove Preliminary Plan, specifically: 1) That lots located on the eastern boundary of the property, adjacent to the West Fork of the Upper Eno, contain at least two acres; 2) That a project-wide impervious surface limit of six percent (6%) (463 , 339 square feet) be applied, with an additional ten percent (10%) (46, 334 square feet) available with approval of the Planning Director; and 3) That the Final Plat show proposed building envelopes, driveways, and an impervious surface allotment for each lot. The Resolution of Approval, modified to show the above changes, is attached.
