Stormwater Management

Stormwater Management for Building Projects

On September 9, 2014 the Borough of Phoenixville adopted a new Stormwater Management Ordinance to minimize the impacts of new development, redevelopment and other earth disturbance activities to protect, sustain and enhance the quality and quantity of all water resources to insure the health, safety and welfare of the citizens and preserve the diverse natural resources and aesthetic and recreational assets of Phoenixville Borough, Chester County and the Commonwealth of Pennsylvania.

In addition to the requirements under local zoning and ordinances, federal regulations require individual land development projects to obtain National Pollutant Discharge Elimination System (NPDES) permits for all land development projects that disturb one acre or more. The 1999 update to the federal stormwater regulations also required municipalities throughout Pennsylvania to obtain NPDES permits for their stormwater discharges. Each permit holder must implement and enforce a stormwater management program that reduces the discharge of pollutants to the maximum extent practicable.

Chester County's Water Resources Authority, through Act 167, has created a county-wide integrated water resources management plan that includes the implementation of the local stormwater ordinance as seen above. More information is available on their website

The Chester County Water Resources Authority has prepared a Homeowner and Small Projects Factsheet to accompany the following changes. A guide created to assist you to develop and implement a stormwater management plan for your property has been created and can be found HERE.

Please see the Planning/Zoning or the Miscellaneous tab the Applications and Permits portion of the website. 

Flood Insurance Rate Maps
The state Department of Community and Economic Development maintains a website containing the new Digital Flood Insurance Rate Maps established by the Federal Emergency Management Agency (FEMA). The site will help users determine if they are located in a floodplain and assist local officials in their creation of floodplain-management strategies to ensure public safety


Phoenixville’s MS4 Program 
Municipal Separate Storm Sewer System Program

Untreated and uncontrolled stormwater runoff is the number one cause of impairment in local Pennsylvania waterways. Polluted runoff is often transported through municipal stormwater systems where it is eventually discharged into streams.

The United States Environmental Protection Agency (EPA) has established a municipal stormwater management program known as the MS4 Program that is intended to improve water quality of the waterways in the United States, by reducing the quantities of pollutants that stormwaters can carry into stormsewer systems during storm events.

As part of the MS4 Program, the Borough of Phoenixville, like other municipalities, holds a permit to discharge stormwater into the local waterways.

As part of this permit, the Borough is responsible for overseeing a stormwater management program that reduces the discharge of pollutants to the maximum extent possible, and that satisfies the water quality requirements of the Clean Water Act.  In Pennsylvania, the MS4 program is administered by the Pennsylvania Department of Environmental Protection (DEP).


The MS4 stormwater management program has six elements known as “minimum control measures” (MCM). It is intended that implementation of these six MCMs will result in an immediate and long-term reduction of pollutants that are discharged into waterways. The six minimum control measures include Public Education and Outreach, Public Participation and Involvement, Illicit Discharge Detection and Elimination, Construction Site   Runoff Control, Post Construction Runoff Control and Borough Pollution prevention / Good Housekeeping.
The Borough of Phoenixville is committed to improving water quality within the municipal watershed through better management of stormwater runoff.  Every resident and business owner needs to participate in the municipal stormwater program by reducing and preventing pollutant runoff from their own property.  They should also report any non stormwater discharges that flow into local waterways to the Borough at 610 933 8801.
