The project is limited to the stabilization of an approximately 100-foot-long bank slope failure between a residence and the Russian River.

The keyway will be located approximately 45-feet from the edge of the river and approximately 100-feet long, eight feet wide, and four to six feet deep. The keyway will include a subdrain composed of drain rock and a permeable drainage pipe and will be backfilled with native materials.
