Londonderry Township Receives Grant for Stream Restoration and Flood Mitigation

Londonderry Township, received more than $700,000 in funding from the Growing Greener Grant Program this month.  The funding will be used for projects associated with streambank stabilization and sediment removal to improve water quality in the Conewago Creek and to meet our Chesapeake Bay Pollutant Reduction Plan mandates.  The creek has a Total Maximum Daily Load, and multiple studies by DEP and the Susquehanna River Basin Commission have determined its ability to sustain aquatic life is impaired.  The funded improvements will include a system of conveyances that channel runoff to one of three bio retention ponds designed to filter pollutants from the runoff.  They will also include the expansion of the riparian buffer to provide filtration of any runoff from areas outside the new conveyances.  Future work on the stream includes legacy sediment removal, stream restoration and flood plain reconnection. 

Londonderry Township takes a comprehensive approach to water quality and flood mitigation that goes beyond minimum requirements to promote the long-term health of the watershed for future generations.  With a proactive approach to capital improvement planning, we can achieve this goal cost-effectively for residents. Thank you, DEP, for continuing to invest in water quality for Pennsylvanians!
