account. The following items were incorporated for the Minimization of water quality Impacts:
- Alignment was designed to minimize wetland and stream crossing impacts.
- 2:1 Slopes were used to reduce structure length.
- Grassed swales utilized to the maximum extent practical.
- Use of open channel design with Rip Rap on Banks only where practical in areas of parallel jurisdictional stream impacts.
- No cut or fill is proposed within the FEMA regulated floodplain.
