Post Construction Storm Water BMP


Wetland along State Route 50, Athens County, Ohio 


 Post Construction BMP Overview


The Ohio Environmental Protection Agency requires post construction storm water management controls through the NPDES General Construction Permit. Post construction storm water BMP design guidance is found in the Location and Design Manual, Volume 2.  Post construction storm water BMP design support is available through the Office of Hydraulics by contacting  Becky Humphreys.

The below documents are provided to supplement the information found in the Location and Design Manual
