Drainage Permits


All permitting forms have been updated for 2023.  Applications revised prior to December 2022 will NOT be accepted. Additionally, permitting fees were updated in the most recent Easttown Township Fee Schedule.

SUBMIT YOUR PERMIT ONLINE* (Permit Portal) - The permit portal adds you to the queue faster, and allows for online payments. HOWEVER, a completed and signed application still needs to be uploaded to the portal or submitted to the Township in person or emailed to easttown@easttown.org

Unsure if your permit application is complete? Use the Application Completeness Checklist.


Drainage permits are generally required for proposed changes that will significantly increase the impervious surface of the parcel/lot.  Please refer to Chapter 388 Stormwater Management of the Township of Easttown Code for specific details.

  • Examples of projects that may require a Drainage permit include, but are not limited to:
    • Hardscape improvement/installation (i.e. driveways, patios, walkways, retaining walls, etc.)
    • Adding accessory buildings/structures (i.e. sheds, gazebos, decks, garages, pools/spas, etc.)
    • Expanding buildings/structures (i.e. home additions, covered porch/patio, etc.)
    • New Construction


  • Drainage Permit Application
  • Floodplain Permit Application
    As of September 29, 2017, Floodplain Permits, in addition to other applicable Township Permits, are required prior to any construction or development being undertaken within a floodplain. For background, the Federal Emergency Management Agency (FEMA) updated its Floodplain Maps and required Easttown, as well as all municipalities, to update its floodplain regulations to comply with its new Floodplain Maps and to meet the National Flood Insurance Program (NFIP) new minimum floodplain requirements. Using the statewide floodplain ordinance model provided by the Commonwealth, Easttown adopted Ordinance 428-17 on May 15, 2017. By adopting this Ordinance, it allows the NFIP to continue making flood insurance available to Easttown residents. To check to see if your proposed project falls within a floodplain, please visit http://www.chesco.org/2198/ChescoViews or https://msc.fema.gov/portal.  For questions regarding Ordinance 428-17 and/or the Floodplain Permit Application, please contact the Zoning Officer.
