Stormwater Management - We Need to Hear from You!
|Chester County is working to review and update the County-wide Stormwater Management Model Ordinance first adopted in 2013. The updated model ordinance will be developed in close consultation with the County’s municipalities to protect public health and safety and to improve water quality by implementing drainage and stormwater management provisions for new |
land development and construction.
We are asking for your perspective on the stormwater issues impacting Chester County by completing at least one of two survey options.
These surveys will remain open until the end of the day on Friday, April 22. Please use this opportunity to provide us with your input at your earliest convenience.
