NARRATWE
STORMWATER MANAGEMENT MEASURES:
The project site is located in New Hanover County, North Carolina. 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.
