Land disturbing on the site will exceed one acre, which requires the site to comply with the State Regulations. The stormwater runoff from the 3.34-acre development will be directed to stormwater infiltration trenches. The stormwater systems are designed to accommodate this site at 100% impervious area lot coverage. This is a redevelopment site and drains to SC waters. CONSTRUCTION SEQUENCE: The Contractor will install the gravel construction entrance and silt fence prior to beginning any clearing and grading operations. Additional sift fence will be installed when and if conditions warrant during construction. Disturbed areas will be landscaped or seeded upon completion. The infiltration areas will be cleaned out to remove any sediment that accumulates during construction. 4" 051116/2005 MON 10:41 FAX 910 343 9604 Norris, Kuske, Tunstall b02/004 STORMWATER SYSTEM NARRATIVE LUMINA COMMONS WILMINGTON, NORTH CAROLINA For Plaza East Associates, LLC 125 Scaleybark Road Charlotte, NC 28209 (704) 561-5238 40'swfNin&- N CAR 2Q� .•'E ESs ZI 96 �4 , pH!
