Countywide Model Stormwater Ordinance

 Home / Departments / Planning Department / Current Projects / Countywide Model Stormwater Ordinance

The Delaware County Planning Department, with Cedarville Engineering Inc., updated the Countywide  Model Stormwater Management Ordinance.

The updated Model Ordinance is designed to comply with the regulatory requirements of Pennsylvania Department of Environmental Protections’ (PA DEP) National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) program. The updates incorporated into the Model Ordinance are also designed to comply with the provisions included in PA DEP's 2022 Model Stormwater Ordinance.

The updated Model Ordinance is intended to be applicable countywide, and it is Delaware County’s first step in determining the feasibility of countywide updates for Act 167 plans. Below are links to the word documents of the updated Model Ordinance and Appendices B and I, which have changes. Appendices A,C,D,E,F,G,H and J had no changes in this update to the Generic Crum Creek Ordinance.
