Stormwater Capital Improvement Plan
Chesapeake Bay Total Maximum Daily Load (TMDL)
The U.S. Environmental Protection Agency (EPA) established the Chesapeake Bay Total Maximum Daily Load (TMDL) with the express purpose of restoring water quality in the Chesapeake Bay and its tributaries by identifying the required reduction of pollution loads of nitrogen, phosphorus and sediment reaching the Bay.
This permit allows for the implementation of the agreement between the Commonwealth and EPA. This agreement provided MS4 permittees a phased approach, over three five-year permit cycles, in order to meet requirements of the Chesapeake Bay TMDL conditions of the permit.
Chesapeake Bay TMDL Stormwater Capital Improvement Projects
We contracted with ARCADIS Inc. to provide information on cost estimates for recommended stormwater treatment strategies in order to assist Chesterfield County in planning for future capital costs and the identification of potential stormwater projects. View the document (PDF) that was prepared.
Municipal Separate Storm Sewer System (MS4)
The Virginia Department of Environmental Quality (DEQ) reissued the county’s Municipal Separate Storm Sewer (MS4) Permit Number VA0088609 on December 17, 2014. The purpose of the permit is to control and manage stormwater and reduce the pollutants discharged from the MS4 to local waters.
Projects in Fiscal Year 2014
County staff initiated the financial planning in an effort to address the costs associated with the future requirements of the stormwater permit and water quality improvements. We also initiated the construction process for three projects:
- Mid-Lothian Mines Park Stream Restoration
- Regional Stormwater Facility - LTC 20/25
- Wren Nest Stream Restoration
These projects are funded, in part, by the DEQ’s Stormwater Local Assistance Fund and will assist the county in complying with the requirements of the Chesapeake Bay TMDL conditions.
Projects in Fiscal Year 2015
The Chesapeake Bay TMDL compliance plan listed funding for two additional projects:
- James River High School BMP (Best Management Practice) Retrofits
- Proctors Creek Outfall Retrofits
Projects in Fiscal Year 2016
The Chesapeake Bay TMDL compliance plan listed two additional projects:
