General Project Narrative:
(Description of Minimization of Water
Quality Impacts)
This is an intersection and surrounding area improvement project located at the intersection of Torrence Chapel Road and West Catawba Avenue.
There is one site along the project where temporary and permanent surface water impacts will occur. These impacts will occur at a headwall installation and a proposed ditch
entering a jurisdictional stream. Rip rap will be installed along the ditch line to lower water velocity into the jurisdictional stream.
NCDOT will attempt to avoid and minimize impacts to streams to the greatest extent practicable during project design.
