Stream restoration in progress

Stream Restoration Project Description:

Preservation Parks of Delaware County selected the design-build team of ERC and B&N for the restoration of McCammon Creek (2,000’), realignment of its tributaries, and floodplain expansion throughout 36-acres of previous agricultural property with the Alum Creek watershed. As a result, the historically channelized and entrenched McCammon Creek is now the focus of a children’s natural play area within the park.

The project relocated two tributary channels running parallel to Bale Kenyon Road. Through collaboration with B&N and Preservation Parks staff, ERC was able to construct new stream channels “in the dry,” which prevented sediment from entering the newly restored McCammon Creek and encouraged native planting and seeding establishment prior to receiving wet-weather flows. Moreover, the project restored the eroding banks of McCammon Creek and provided access to a new floodplain adjacent to Alum Creek. Finally, ERC utilized the abandoned stream channel to create a 1-acre wetland.

Because this project used partial grant-funding, ERC worked closely with the project stakeholders to identify cost-saving approaches to the construction. For example, ERC reused onsite stream substrates in the newly constructed channels and harvested localized woody debris for in-stream structures. Furthermore, the team used excess spoils to grade an adjacent park area planned for future parking. Due to the cost-saving strategies, ERC maximized project funding and restoration dollars. Finally, the design-build team completed the project in late 2020.
