Document Description
Large winter storms in 2005-06 resulted in a slide above Alderpoint Road that blocked the inboard drainage ditch. The slide caused water to flow across the road, which saturated the fill prism and caused the road shoulder to slip. The project involves construction of a subsurface edge drain along the uphill side of the road and reconstruction of the damaged roadway. Construction of the edge drain involves excavation of a 350-foot long by 2-foot wide by 4-foot deep trench along the uphill side of the road and installation of 350 linear feet of 8-inch diameter perforated plastic pipe in the trench along with filter fabric and permeable backfill material.
