Restoring Coastal Plain Streams: Functional Uplift through Baseflow Channel and Valley Restoration

The Bureau of Watershed Protection and Restoration in Anne Arundel County, Maryland, has initiated the development of projects that were identified in the comprehensive watershed assessments of the County’s waterways. These projects are being implemented to provide ecological enhancement and support the requirements of the National Pollutant Discharge Elimination System permit issued to the County and to assist in meeting pollutant load reductions associated with the Chesapeake Bay Total Maximum Daily Load.

This presentation is focused on the Cat Branch Stream project that included the enhancement of and creation of non-tidal wetlands and floodplain reconnection through the restoration of 1,500 linear feet of perennial stream channel. This presentation will discuss the programming, assessment, prioritization, and overall project goals. Additionally, it will outline site-specific restoration design considerations and the construction methods implemented to fully restore this valley; and ultimately provide for riparian habitat and ecological functional uplift of this degraded perennial stream system.
