This is a Statement of Work for the Old RT 30 Streambank Stabilization project at Townshend Lake in Townshend, Vermont, administered by the U.S. Army Corps of Engineers. The document provides informational photos and schematics illustrating the streambank stabilization work area and construction methodologies required for the project.

The project involves stabilizing approximately 0.6 miles of eroding streambank along the Deerfield River near the Yellow Gate area at Townshend Lake. The work requires construction of stone toe walls using placed rip rap, with materials placed according to specified dimensions and design standards outlined in technical schematics. Key construction requirements include: stone toe walls constructed with stones of specified size (no stone smaller than 3 inches), staggered joints between adjacent tiers, footer rock embedded minimum 4 feet below channel bottom with 6 feet maximum stacked section exposure, careful stone placement to maximize contact between adjacent stones, and stones dipping toward embankment to resist sliding. The stabilization work also involves rip rap slope protection along portions of the streambank. A separate silt storage area is designated for material management during construction. The document references the Vermont Rivers and Roads Field Manual and Vermont Standard River Management Practices as design standards. Informational photographs show the existing unstabilized streambank conditions, detailed cross-sectional schematics of the proposed toe wall and slope protection systems, and the broader project area boundaries marked along the stream corridor.
