Stormwater from roads, buildings, lawns and parking lots carry pollutants to streams and rivers to the Chesapeake Bay. Hanover County's stormwater brochure (PDF) talks about improving water quality in our streams and rivers.

Requirements for erosion and sediment control, drainage, flood plains and wetlands, protect waterways and apply to these activities:
  • Land clearing / tree removal
  • Areas with soil fill or remove soil
  • Construction (homes, barns, riding rinks, trails, ponds, roads, stream crossings, etc.)

Municipal Separate Storm Sewer (MS4) Permit

Additionally Hanover County administers a Municipal Separate Storm Sewer (MS4) permit to reduce and remove pollutants from streams and rivers. As a requirement of the MS4 permit Hanover County has developed a Chesapeake Bay Total Maximum Daily Load (TMDL) Action Plan (PDF) to improve the water quality of the Chesapeake Bay. View a summary of projects addressing the action plan (PDF).
