Document Description
Heavy rains in late 2005 and early 2006 resulted in storm damage to an existing 24-inch diameter and 40-foot long culvert and the adjacent over-side storm drain pipe. High flows also caused erosion of the channel and embankment around the culvert outlet. The project involves removal of the existing culvert, installation of a new 24-inch diameter and 40-foot long culvert, and repairing the embankment. The existing 18-inch diameter over-side drain and down-drain pipes will be removed. A 40-foot long, 9-foot wide, and 7-foot deep area will be excavated and covered with crushed rock backfill. Quarter-ton rock riprap will be placed around the culvert outlet for erosion protection. The 18-inch diameter over-side drain will be reset with new anchors and a new flared end section will be installed at the inlet. After the new culvert and over-side drain are installed the disturbed section of road will be repaved with asphalt.
