• Two cul -de -sac roadways. The first roadway (tentatively named Secretariat Court) will provide access to lots 12 through 19. The second roadway (tentatively named Gallant Fox Crossing) will provide access to lots 2 through 11. • Both roads require stream crossings and Section 401/404 permits by the US Army Corps of Engineers ( USACE) and NC department of Environmental Quality (NCDEQ). These permits have been obtained. STAFF COMMENT- ROADS: Staff has determined that the proposed new roadway layout is consistent with the requirements of the UDO. However, staff does recognize the differences in construction and maintenance between public and private roads. Staff recommends that the roads as proposed be reflected in a revised Private Road Maintenance Agreement (RMA), and that the developer record a disclosure statement with the recordation of the Final Plat. Both documents would acknowledge that the roads do not meet the NCDOT design standards and would require significant improvements to meet those standards if converted to public roads meeting the NCDOT design standards. Staff also recommends that the developer finalize all temporary and final driveway permits for the intersections of these private roads with Triple Crown Drive right -of -way and traffic circle. Utilities — Water and Sewer: The applicant is proposing to serve the project with individual wells and septic systems that will be developed on each lot. STAFF COMMENT - UTILITIES: Orange County Environmental Health approved the previous Preliminary Plat layout identifying septic and well locations for each proposed lot. No significant changes are proposed. Stormwater Drainage: Site drainage will be engineered according to Stormwater Control Measures (SCMs) as provided with the subdivision's approved Erosion Control and Stormwater Permits. STAFF COMMENT - STORMWATER: Orange County Stormwater and Erosion Control has reviewed and issued Erosion Control and Stormwater Permits. They also conducted a Pre - development meeting on -site prior to commencement of land disturbing activity. Staff has continued to monitor the site for maintenance and compliance. Open Space: The flexible development plan denotes the maintenance of a 30 -foot natural buffer along Dairyland Road and a 100 -foot building setback along the perimeter of the project. Open space is identified in and around the existing streams. The total area reserved as open space is approximately 1,678,305 square feet of land area or 38.53 acres. The proposed open space is composed of existing, mature, vegetation and trees with an approximate height of between 50 to 70 feet. Existing vegetation will be supplemented with additional street trees and ornamental vegetation along the roads. STAFF COMMENT — OPEN SPACE. Staff has determined the proposed open space and land use buffers meet the requirements of the UDO.
