Rock Hill Manor Subdivision Storm Water Narrative
This site is currently undeveloped. The site is being developed as a single family
residential development. The property currently drains roughly east to west, with the
east side of the development draining toward Rock Hill Road. The proposed subdivision
will utilize vegetated roadway ditching to convey runoff through the site. The
development will discharge runoff into roadway ditching along Rock Hill Road and to a
wetland located centrally to the development.
The site meets the qualifications of a low density development. The average density for
the development is 0.86 units/acre compared to the maximum of 2 units/acre to satisfy
the requirements set forth by NCDEQ. New paved roads are to be constructed for the
subdivision.
Based on our study and review of the NCDEQ BMP manual and NC Session Law 2006-
246 Section 9 paragraph c, this development meets and/or exceeds the requirements
and intent for low density development.
