A reconnaissance of the project roads, constructed prior to 1990, showed that large volumes of fill had been placed over steep cross slopes. Slumping fills and tension cracks were evident along many sections of these roads, and several large slope failures had already occurred off HAM 22 prior to 2004. These roads cross Es1 and Es2 classified terrain, which is considered to be high and moderate hazard terrain where landslide failures can occur. The reconnaissance level assessment identified the hazard as high along a number of sections of these roads. Specific locations identified as moderate or high hazard are identified in the Road Deactivation Report and the Summary of Work Completed Report. These reports must be read in conjunction with this Project Completion Abstract to understand road conditions assessed in June, 2004 and the residual hazards remaining after the road deactivation project was completed. Previous road deactivation work was minimal with only a few shallow poorly constructed crossditches and partial removal of wood culverts along these roads. No fill retrieval appears to have been completed in the past.
