Graceland Subdivision Storm Water Narrative
The site is currently undeveloped. The site is being developed as a single family
residential development. The site drains to a wetland that exists through the center of
the property.
The site meets the qualifications of a low density development. The average density for
the development is 1.43 units/acre compared to the maximum of 2 units/acre to satisfy
the requirements set forth by NCDEQ. The roads within the development will convey
storm water via curb and gutter to curb inlets which connect to the storm water piping
system. The Hoke County ordinance requires the streets to have concrete curb and
gutter. This system will terminate at grassed swales which ultimately discharge into the
existing wetlands. Swales that terminate at the wetlands provide flow velocities less
than the allowable 2.0 fps. The roads in the subdivision are designed in accordance with
0 14 BIG] I
Based on our study and review of the NCDEQ BMP manual and INIC Session Law 2006-
246 Section 9 paragraph c, Graceland Subdivision meets and/or exceeds the
requirements and intent for low density development.
