French Creek Stormwater Management

PEC manages an alternative stormwater Best Management Practice (BMP) project in urban areas of the French Creek watershed (i.e., in areas of already high percentages of impervious surface cover and in areas of increasing percentages of impervious surface cover). Through this program PEC works with municipal officials and private landowners to site, design and construct the alternative stormwater BMPs.
Background: 

In 2004 the Pennsylvania Environmental Council, in partnership with the City of Meadville, initiated an alternative stormwater Best Management Practice (BMP) project in an area upslope of a flood prone City area. This collaboration was in part prompted by flash flooding and its resulting costly damage, and in part to reduce the pollution risks to the highly diverse biological receptors in French Creek. In 2006, funded by a PA DEP Growing Greener Grant PEC expanded upon that initial effort, by undertaking a program to design and construct additional alternative stormwater BMP projects in the French Creek watershed. The BMP project sites are being utilized as (1) demonstration sites for outreach efforts to municipal officials, engineers, developers and others, and (2) environmental education sites for school children and the general public. As part of that community education component of the stormwater program, PEC facilitated a stormwater management workshop, targeted at municipal officials, since they are critical stakeholders in the effort to reduce the adverse economic and environmental impacts of poorly managed stormwater runoff.

 

The project is focused in and around the urban areas of the watershed: Meadville and Franklin. Not all of the BMP project sites have been chosen as of this date, although several likely project locations and BMP types have been identified. Some of the potential alternative BMPs envisioned under this project include: native plant cover; vegetated wet ponds, raingardens, bioswales, wetlands, porous pavement, green roofs, and riparian buffer strips.

Project Goals: 

Implementation of traditional and alternative stormwater best management practices in areas of already high (> 25%) percentages of impervious surface cover and in areas of increasing percentages of impervious surface cover (i.e., 10 - 20%). The resulting alternative stormwater BMPs are allowing for significantly larger amounts of stormwater to be infiltrated into the soil, thereby reducing the amount of runoff needing management, reducing peak stormwater loads to streams, and helping to maintain stream base flows. The alternative stormwater BMPs resulting from this project will require low maintenance, and be less costly and very effective in pollution prevention when compared to conventional stormwater BMPs.

Major milestones/successes to date: 
Five alternative BMP projects are either under design currently or are completely designed.
Current/upcoming plans: 

Construction of those projects will begin in the near future and continue throughout the next year.
