Document Description
To provide additional security and to prevent unauthorized vehicles, other trespassing, and reoccurring vandalism near California Aqueduct (Aqueduct) Check 18, the Department of Water Resources (DWR) San Luis Field Division will create an approximately 0.64-mile V-ditch running adjacent to and parallel with the DWR property line; all work will be in the DWR right of way. The V-ditch will begin at approximately Aqueduct MP 143.16R and continue to approximately MP 143.80R, where it will intersect an existing fence. The V-ditch will be constructed by using a water truck to control dust by spraying the area, then a grader with an angled blade will make several passes to form an approximately three feet deep and up to 10 feet wide V-shaped ditch. The excavated soil will remain on the sides of the V-ditch as a berm to further deter vehicle entry.
