Stormwater Management 

Stormwater management is the effort to reduce runoff of rainwater or melted snow into streets, lawns and other sites and the improvement of water quality, according to the United States Environmental Protection Agency (EPA).

In natural settings, rainwater or snow melt slowly soaks into the ground surface or flows overland into adjacent streams. In developed areas, natural surfaces are often replaced with hard surfaces such as streets, sidewalks, parking lots, homes or other similar structures. If not properly controlled, stormwater runoff from those areas can overwhelm streams and embankments and could cause major flooding, soil erosion and water pollution.

A growing awareness of just how vulnerable Pennsylvania’s waterways have become to damage from stormwater runoff has resulted in legislation requiring municipalities like Cranberry to obtain permits before discharging stormwater runoff into waterways like Brush Creek.  

Under federal regulations, certain municipalities within urbanized areas, including Cranberry, are required to apply for Municipal Separate Storm Sewer System (MS4) permits.  Permit-holding municipalities are required to create and implement plans reducing the level of pollutants, including silt, that enters their waterways. Part of Cranberry’s program is designed to reduce soil erosion.

The Township has a permit from the Pennsylvania Department of Environmental Protection to operate the Municipal Separate Storm Sewer System (MS4). These permits, valid for five years, require communities to put stormwater management programs in place that reduce the discharge of pollutants, educate the public, and protect local water quality.

Cranberry Township is also required to develop and implement a Pollution Reduction Plan (PRP) under the National Pollutant Discharge Elimination System (NPDES) General Permit For Stormwater Discharges From Small Municipal Separate Storm Sewer System (MS4).

Stormwater System Maintenance

Cranberry’s current stormwater management system is extensive.  Parts of it are privately owned, other parts are municipal property. All property owners are required to keep their stormwater facilities in working order at their own expense. Cranberry currently spends over a million dollars a year to maintain its portions of that system. Until recently, Cranberry financed its stormwater system and flood control maintenance from general tax revenues. However, with the state’s updated regulations, that expense has grown.

Pennsylvania’s Department of Environmental Protection has issued a series of updated regulations designed to reduce water pollution and protect property against flooding from stormwater. Those regulations must be implemented by 2023.
