The road project involved widening S-62 (College Park Road) – from US 17A to approximately 500 feet South of Savannah Road – to five lanes for a total distance of 3.8 miles, impacting a total of 0.467 acre of waters, including 0.217 acre of wetlands (0.196 acre cut/fill and 0.021 acre mechanized land clearing) and 943 linear feet (0.25 acre) of tributaries. As the project was not located within the service area of any approved stream mitigation banks or in-lieu fee programs, an on-site, in-kind mitigation within the same watershed as the proposed impacts was approved.
The mitigation site is approximately five (5) miles east of Summerville in Berkeley County South Carolina and is located immediately adjacent to the existing College Park Road and converges with King's Branch approximately 0.75 miles downstream. The site consists of approximately 4.0 acres of land within the SCDOT Right-of-Way along College Park Road.
The mitigation work was begun in 2014 and completed in January 2015.
The primary goal of this stream restoration project was to relocate the headwaters of the unnamed tributary (UT) to King's Branch to a position outside of the footprint of the proposed alignment of College Park Road. Restoration goals included reducing sediment loads from channel banks, reducing stressors on water quality, providing/enhancing flood attenuation, and restoring and enhancing aquatic and riparian habitat for flora and fauna typically associated with riparian corridors within the Mid-Atlantic Coastal Plain Eco-region. These goals were accomplished through the following objectives:
|Riparian Buffers||3.5 acres|
|Total Easement Acreage||4.0 acres|
