About the Project: Our MSRA October 2025 fall field trip is to one (1) of the Maryland State Highway Administration (SHA) Intercounty Connector (ICC) stream restoration projects over 10 years after construction. This is a great opportunity to view an established restoration project!
The Northwest Branch Stream Valley Unit 5 (NW-160) project was one of the largest stream restoration efforts on the ICC project. The NW-160 project involved extensive coordination between the Maryland Department of Natural Resources (DNR), SHA, and the Maryland-National Capital Park and Planning Commission (M-NCPPC). Stream restoration activities featured the use of large wood structures in place of the typical stone and rock structures - wood structures were either placed along streambanks to prevent bank erosion or in the center of the stream channel to increase aggradation of the streambed and floodplain access during storm events. We will explore this innovative approach, used widely in other parts of the country, which took advantage of trees harvested from the ICC project and which yielded more natural aesthetics.
