1. Please provide complete site plans on full plan sheets at a scale of no smaller than
1 "=50' with existing and proposed topographic contours shown.
2. Please provide an inventory of imperviousness surfaces in each drainage area.
The inventory should include all proposed building footprints, roads, driveways,
sidewalks, gravel-surfaced areas, amenity areas, etc. A Stormwater Management
Plan (SMP) must be provided for any drainage areas that exceed 24 percent
imperviousness. For each BMP, provide a completed BMP Supplement Form
with all the required items (see hit :/Lh2o.enr.state.nc.us,/su/bmp formslltm). Per
NCAC 2B 15A: 02H.1000, a "drainage area" is defined as "the entire area
contributing surface runoff to a single point."
