OVERVIEW
This report contains the storm water management overview for the proposed residential
development Timberland Ranch on Calloway Road in Hoke County. The project site is
currently un—developed. The proposed site consists of 524.7 acres and approximately
11.24 acres will be disturbed as part of this project for the construction of the site
improvements.
The proposed site is located in Flood Zone `X' as shown on FEMA FIRM Panel 3710940600J
with an effective date of 10/17/06 and Panel 3710940400J with an effective date of
10/17/06. Flood zones are subject to change by FEMA.
There are no existing stream or wetland features on the proposed property.
The proposed site satisfies a Low Density Project as a Phase II tipped county designation in
Hoke County. The development of the site will result in an impervious area of 1,010,543sf
(23.20ac — 4.43% impervious). The BUA is less than the 24% threshold and there are less
than two dwelling units/acre. Therefore, no Stormwater Control measures are required for the
project site. In exchange for limiting the BUA, dispersed flow will be maximized and
stormwater conveyances will be vegetated.
