Funding: Natural Resources Conservation Service – $10,000 and Bucks County Conservation District$8,000
Matching Funds: $10,000
Consultant: F.X. Browne

Project Partners: Haines and Kibblehouse

This project, on Cooks Creek in Durham Township, restored 90 feet of severely eroding streambank.  Before restoration began the project site was approximately a 10 foot vertical bank that was contributing a large amount of sediment to the stream.

The restoration of this site involved grading the bank from vertical to a more gradual slope, installation of one rock vane to deflect high flows away from the bank, and as the site was on an outside bend of the creek that is subject to high erosion stresses, stone was placed at the base of the bank (a “boulder toe”) to maintain the stability of the bank.  Once the grading and installation of the rock vane and boulder toe was complete, BCTU members installed erosion control fabric on the bank and then planted the site with native trees, shrubs and wildflowers. 75 native trees were planted, native willows and dogwoods were planted at the base of the bank and the area was seeded with native wildflowers.

The completed project benefits Cooks Creek by reducing sediment, the trees that were planted will shade the stream and will be a source of leaf matter and woody debris, and the wildflowers will create habitat for terrestrial insects.
