Water Line Replacement Under Pilarcitos Creek at Strawflower Village

Water Line Replacement Under Pilarcitos Creek at Strawflower Village

The CCWD is proposing to replace the water line under Pilarcitos Creek. The existing 8-inch pipeline crossing beneath the creek is one of only two pipelines supplying water to areas of the CCWD south of the creek, including downtown Half Moon Bay. The existing pipe has reached the end of its useful life and a break underneath the creek bed would impair water delivery and could potentially damage the environment. A break in the water line would be difficult to detect, could cause potentially significant water loss, impair water quality, and cause liability to the CCWD with potential fines from the U.S. Army Corps of Engineers, Regional Water Quality Control Board, or California Department of Fish and Wildlife. The CCWD completed an initial phase of water line replacement work in June 2017 that consisted of installing approximately 400 ft of 8-inch pipe within the Strawflower access road from SR-1 that ensures water supply to commercial customers in the event of a problem with the existing pipe under the creek. The approximately 450-foot-long new pipeline would be installed using horizontal directional drilling under the creek from the Strawflower Village Shopping Center to Oak Avenue, with staging areas in the back of the shopping center and in Oak Park extending down Pilarcitos Avenue to the south.
