General Project Narrative: State project 17BP.12.R.13 involves the replacement of Gaston County Bridge #0008 on SR 2209 (Wesleyan Dr.) over an Unnamed Tributary of the South Fork Catawba River.
(Description of Minimization of Water The existing bridge consists of 1@ 25' - 5", and 1@ 25' - 8", reinforce concrete deck on I-beams. It is to be replaced with a 1@ 60' - 0" Cored Slab Bridge at the same location.
Quality Impacts) All stormwater from the bridge and roadway approches will be collected by a storm drainage systems and discharged into the surtace waters as it presently does. In the
northeast quadrant however, an effort to gain grass swale treatment has been made by pulling back the existing drainage outfall and providing a 30' grass lined 'V' ditch to treat
runoff as it approaches the pond.
