Update:

 

A resounding “thank you” to my partners for the execution of the Perkiomen Mapping and Flood Mitigation Plan, which is complete and will be posted soon on the Perkiomen Watershed Conservancy website at www.perkiomenwatershed.org/perkiomen-flood-study.  

The Plan is the culmination of 18 months of intense engineering work to determine not just where flooding occurs throughout the Perkiomen Creek watershed but what mitigation strategies would be helpful in slowing the flow of stormwater, infiltrating more stormwater back into our groundwater, and identifying how municipalities can work together to further these regional goals.  

Flooding has been occurring throughout the Perkiomen Creek watershed for many years. Historic villages and millworks developed along the Perky and its tributaries since colonial times expanded into larger suburban communities, and the current population of the watershed is estimated to be around 85,000 people. The Perkiomen Creek watershed is also blessed with rich farmlands and extensive open spaces, rugged hills and natural areas that are home to endangered and threatened plants and animals.  

Protecting our communities and landscapes from devastating floods, like Hurricane Ida in 2021, will require all of us to do our part. The Perkiomen Mapping & Flood Mitigation Plan shares actions that can be taken by large or small property owners individually, as well as outlining how communities can work together to reduce flood levels, enhance our groundwater supplies, and protect our built communities as the threat of severe storms continues in the future. 

For communities in my district, cooperation with upstream neighbors will be critical. But we can each take greater care of the stormwater that falls on our properties locally. By installing rain gardens and converting mown grass areas to meadows, we can all do our part to help protect water quality and reduce flooding.

The Perkiomen Project

In the past decade, dozens of large storms and extreme weather events have passed through Pennsylvania causing extensive damage to homes, businesses, and infrastructure, costing millions of public and private dollars to repair and reopen. One of the more devastating storms was Hurricane Ida (2021) which quickly dumped five to ten inches of rain in southeastern PA. This led to massive floods throughout the region and caused the USGS gage on the Perkiomen Creek at Graterford to max out at 24 feet. The final estimate for the day was 26.5 feet; flood stage begins at 11 feet.
While the cost of this flooding from Hurricane Ida is estimated to be over $100 million in Pennsylvania alone, within the Perkiomen Watershed, two people died and 75 homes were destroyed. Historical data tells us that these types of weather events are not only more common as witnessed in the past 20 years but are predicted to be more damaging and more deadly in the years to come.
Pennsylvania must take steps now to prevent future flooding and mitigate future risks. The Perkiomen Project, started by Representative Webster, brings together 4 counties and dozens of municipalities to study the entirety of the Perkiomen Watershed to create a comprehensive analysis of flooding along the Perkiomen Creek and its tributaries. The mapping and data will then be able to identify areas at most risk of flooding and what mitigation efforts need to be implemented.

Perkiomen Watershed Tour

In March 2024, Rep. Webster was joined by the Acting Secretary for the Pennsylvania Department of Environmental Protection Jessica Shirley, her staff, Majority Leader Representative Matt Bradford, and Montgomery County Planning Commission official Drew Shaw to tour the lower Perkiomen watershed and speak with some of the people who were directly impacted by Ida and who continue to face challenges regarding flooding. 

The tour heard from officials from the Collegeville Borough, Schwenksville Borough, and Montgomery County, as well as staff from Providence Place and the Perkiomen Watershed Conservancy.
