This proposal is for a 20-lot residential subdivision on this 10.31-acre tract at a density of 1.94 du/ac. The development includes approximately 2.53 acres of common area east of the TVA powerline easement where the steepest slopes are located. The property is zoned RN-1 (Single-Family Residential Neighborhood) / HP (Hillside Protection Overlay) district. The RN-2 zone requires a minimum lot size of 10,000 sqft and the proposed lot sizes range from 10,000 to 29,600 sqft.

The entire 10.31-acre property is within the HP (Hillside Protection Overlay) zone, except for .06 acres on the north portion of the property. The maximum disturbance allowed is 6.9 acres, and this is for the grading required to install the infrastructure and the house lots, and post-construction once the properties are sold. The preliminary grading plan (Sheet 4) shows the proposed limits of disturbance, which is approximately 5.4-acres. This calculation does not include the disturbance required for the detention pond and swales required to direct stormwater to the pond. On the final plat, the amount of disturbance allocated to each lot must be provided. This is necessary to ensure the entire development complies with the HP overlay standards over time.

Staff is recommending approval of the requested intersection spacing variance because the reduced intersection spacing is an existing condition that the applicant is matching. Road 'A' aligns with Pilleaux Drive to create a four-leg intersection, which is the preferred alignment for the new road. Because of this, Road 'A' to be less than 300' from Woodberry Drive. There is sufficient distance between the two intersections to allow left turn movements from both streets without creating a conflict.
