Any project in the stream corridor (including zero order streams) that is explicitly designed to enhance the function, stability, and ecosystem services of an urban stream.
Example projects include: legacy sediment removal, floodplain reconnection, and natural channel design. Stream restoration projects will be evaluated on their ability to meet one or more of the following criteria:
- The project was part of an integrated watershed-based approach.
- The project meets or exceeds clearly stated goals and objectives that were based on an assessment of critical stream functions.
- The project has successfully withstood significant flood events without damage.
- The project utilizes innovative stream restoration techniques including but not limited to floodplain reconnection, legacy sediment removal, and natural channel design.
- The project maximizes biological uplift within the stream reach.
- The project minimizes the intrusion or damage to the stream corridor or floodplain
- The project improvement is substantiated by post-construction monitoring and/or assessment

The Cabin Branch Stream Restoration is a showcase for Regenerative Stream Channel (RSC) restoration technology, highlighting within one project three prototype RSC applications for water quality improvement in streams degraded by stormwater runoff: 1) an End of Pipe Retrofit utilizing removal of legacy sediments; 2) a retrofit of an out-dated stormwater dry-pond, capturing water at parking lot level and releasing it through a RSC system to receiving downstream waters, and 3) a sand seepage wetland which using the standard construction sequence and raising the incised stream channel. By installing a system of cobble riffles, berms, seepage wetlands, shallow pools, and native plants, we are integrating ecosystem restoration with stormwater runoff management, restoring stream and wetland function, reconnecting the stream to the floodplain, re-establishing historic plant communities, and restoring remaining headwaters, adjacent floodplain, and riparian areas of Cabin Branch.

Our jurors appreciated this project’s use of innovative stream and floodplain restoration techniques that increased floodwater storage potential, created wetlands, improved infiltration, reduced stream bank erosion, and increased filtration of stormwater runoff. These restoration techniques resulted in improved water quality both on-site and downstream. As one of Pennsylvania’s first applications of floodplain restoration as a stormwater BMP, this project vastly improved stream function and the site’s ecological biodiversity while making efficient use of remaining undeveloped land within the property.

This project focused on the restoration of a seepage wetland ecosystem. It involved filling a severely eroded channel, installing rock and riffle grade control structures, and establishing a native plant community in the channel’s riparian zones. The project also utilizes innovative stream restoration techniques such as a “bubbler” to attenuate discharge energy and increase the flow path, thereby allowing a greater treatment area.
Thank you to all our contestants who participate in the 2014 Best Urban BMP in the Bay Award !
We’d like to extend our deepest gratitude to the sponsor of the 2014 BUBBAs.
This year’s contest would not have been a possibility without you!
