Chester County Commissioners' Adopt 2022 County-wide Stormwater Management Model Ordinance
The 90-day period for Pennsylvania Department of Environmental Protection (PADEP) to review the final 2022 County-wide Act 167 Stormwater Management Model Ordinance ended on November 24, 2022. Under the Pennsylvania Stormwater Management Act (PA Act 167), all Chester County municipalities, both MS4 and non-MS4 permittees, are required to adopt stormwater ordinances consistent with the County's Model Ordinance by May 31, 2023.
The updated Model Ordinance, summary of changes table, Matrix of Minimum Mandatory Standards, and other resources are available at chesco.org/StormwaterOrdinance. Any questions about the updated Model Ordinance can be submitted to [email protected].
PDFs and recordings from two workshops CCWRA hosted in May 2022 to assist municipalities with updating their stormwater ordinances are available here.
To ensure that our residents and businesses are equipped to respond to evolving water resources needs, Chester County is leading updates to the Watersheds Plan and the County-wide Stormwater Management Plan.
Clean water in our groundwater aquifers, streams and lakes is critical to long-term healthy communities. Learn about PADEP's assessment program, resources from MS4 municipalities, and information about TMDL pollution reduction programs.
CCWRA provides information on FEMA floodplains as well as real time stream flood monitoring through a partnership with USGS. The Authority also provides flood protection in the Brandywine Creek watershed through the operation of four flood control dams, and has information on preparing for flooding emergencies.
Find both interactive and print-ready maps on water quality conditions, floodplains, and other key water resources components, as well as reports on water conditions in the County, and various factsheets.
Chester County is fortunate to have watershed and conservation organizations that are active with on-the-ground improvement projects, outreach and community education.
CCWRA assists with sustainable water management by providing reservoir water supplies, through planned and managed water releases from Chambers Lake Reservoir. Learn about our reservoir management as well as water conservation tips.
