l 14 t Plan to reduce the amount of impervious surface and cause infiltration of storm water runoff to prevent the pollution of water supply reservoirs. (This subdivision is located in the Upper Eno and the Back Creek protected watersheds. No streams that require protection are located on the property. The stream shown on the western portion of lot 5 will be protected because it is outside the designated building envelope as shown on the plat and described in the restrictive covenants. Furthermore, a public road creates more disturbance [11,400 sgft.]and more impervious surface [2880 sgft.]than a private road.) 5. Topographic and environmental features, such as streams, steep slopes, or watersheds,that would be adversely affected by the use of roads constructed to State standards because of factors such as significant amounts of earthwork(cut and fill)that would contribute to increased runoff of stormwater and siltation. (Building the roads to State standards would require clearing and grading significantly more area than with the proposed private road. A public road must be a minimum of 18 feet wide instead of 12 feet wide. A proposed public right-of- way must be cleared entirely of all trees and underbrush. Trees and natural understory may remain in a private right-of-way,provided there is adequate clearance for larger vehicles) 6. The site is already developed to 100%of the capacity which could be achieved after approval of the subdivision and some or all of the non- conforming aspects of existing development on the site will be made more conforming as a result of the proposed subdivision, and all conforming aspects of the development will remain conforming. (Not applicable) 7. There is only one subdivision road proposed. Its length does not exceed 350 feet. It serves no more than five lots. Its grade does not exceed nine percent. The land being subdivided is not connected to or is part of another subdivision required to be served by public roads. In addition,the average lot size within the subdivision is at least 40,000 square feet. (Not applicable) EVALUATION SUMMARY: The proposed private road is justified through lower density, larger setbacks,protection of natural features, and additional screening. In addition, the subdivision is located in two protected watersheds where disturbance and impervious surface should be minimized. Planning Staff recommends that the proposed road be approved as a Class B private road.
