Project Selection
The stream restoration project was identified as a top priority project in the Cabin John Watershed Study in 2004. The original restoration of Lower Booze Creek was completed in 2012, but has sustained significant damage due to a number of different factors. The primary objective of the project is to develop a repair design that restores the initial restoration goals:
• Channel stabilization • Floodplain reconnection • Aquatic and riparian habitat enhancement • Protection of existing utility infrastructure
The project site is located in Bethesda, Maryland, and encompasses approximately 3,583 linear feet of stream restoration between River Road and Cabin John Parkway.

Booze Creek is located within the Cabin John Creek Watershed. Cabin John Creek drains to the Potomac River. The project starts downstream of River Road and ends upstream of Cabin John Parkway.

Current Stream Condition
Lower Booze Creek - Exposed sewer line and erosion of channel bed and bank.
Lower Booze Creek - Failure of cross vane structure and bank erosion.
The Booze Creek watershed is associated with a very high amount of impervious area that increases runoff from rooftops, roads, parking lots and other impervious surfaces during storm events producing flashy flows with high velocities. This causes channel degradation or erosion of the stream bed and banks, and threats to utility infrastructure.
Storm damage occurred very soon after initial construction of the stream restoration project that initiated structural failures. Subsequent storm events continue to erode the channel, degrade natural resources and threatens infrastructure.
Restoration Actions Montgomery County DEP is implementing a repair plan to address long-term channel stability and achieve water quality, ecological and infrastructure improvements. The Lower Booze Creek repair will include modification to the channel alignment and cross section to provide stable channel geometry that reduces energy (velocity and shear stress) to withstand large storm events. Proposed channel and floodplain grading will help stabilize existing eroded streambanks, reduce stress that causes erosion and provide improved floodplain access during storm events. Floodplain access spreads out flow over a larger area, which reduces erosive velocities and provides water quality benefits through sediment deposition and nutrient processing.

Proposed instream structures include riffle habitat structure, toe boulder protection, outfall stabilization, and pool enhancement features to reproduce natural stream conditions and provide long-term channel stability and enhanced aquatic habitat. The stream repair will also include native tree, shrub and other plantings along the channel and floodplain to further help in stabilizing streambanks, enhance riparian and instream habitat, and uptake of nutrients.
