Document Type
NOE - Notice of Exemption
Document Description
Westlands Water District (WWD) has requested permission to encroach in DWR's right-of-way to excavate an approximately 10-foot-wide by 10- foot- long by 6-foot-deep area at MP 118.45L. WWD will first remove a protective concrete cylinder and will then excavate about 10 cubic yards of material. This material will be stockpiled next to the excavated area. Then, a 5-foot section of vertical PVC pipe that ties into the subline will be removed to access the air release valve. The valve will be inspected and will either be repaired or replaced using hand tools. Once the air valve is repaired or replaced, the 5-foot section of vertical PVC pipe will be replaced with galvanized pipe. The area will be backfilled and compacted, and the protective concrete cylinder will be installed in its original location. WWD benefits.
