Castaic Lake Water Agency
Memorandum
December 6, 2017
To: CLWA Board of Directors
From: Brian Folsom
Engineering and Operations Manager
Subject: Approve a Resolution Adopting the Mitigated Negative Declaration and
Mitigation Monitoring and Reporting Program Under the California
Environmental Quality Act for the Central Park Recycled Water Main
Extension (Phase 2A) Project
SUMMARY
On September 22, 2017, the Castaic Lake Water Agency (CLWA) released a Draft Initial
Study/Mitigated Negative Declaration (IS/MND) for the Central Park Recycled Water Main Extension
(Phase 2A) Project (Project) for public review in compliance with the requirements of the California
Environmental Quality Act (CEQA). CLWA is the CEQA lead agency and must adopt the IS/MND and
Mitigation Monitoring and Reporting Program (MMRP) prior to approving the Project for design. Staff
recommends that the Committee review the IS/MND and MMRP and recommend that the Board of
Directors adopt the attached resolution approving the IS/MND and MMRP.
DISCUSSION
Background and Project Description: The Draft Recycled Water Master Plan (Draft RWMP) sets forth a
plan to expand the recycled water system in the Santa Clarita Valley to offset potable water demands.
The existing recycled water system is referred to as Phase 1 and provides approximately 450 acre-feet
per year (afy) of recycled water to golf courses and median landscapes. Phase 2 includes four separate
phases (2A, 2B, 2C and 2D) that will expand the recycled water system to the east, west and south
portions of the Santa Clarita Valley. The Central Park Recycled Water Main Extension (Phase 2A)
Project will provide recycled water to the service areas of Santa Clarita Water Division (SCWD) and
Valencia Water Company (VWC) by using recycled water from the Valencia Water Reclamation Plant
(WRP). It is estimated that up to 560 afy would be available to SCWD and VWC to serve nearby existing
irrigation customers along the pipeline alignment.
As proposed, up to a 24-inch transmission pipeline would originate at the Valencia WRP at The Old
Road and extend for approximately 5.25 miles, or up to 33,000 linear feet, along Rye Canyon Road and
Newhall Ranch Road. At the Newhall Ranch Road and Bouquet Canyon intersection, the proposed
Project will continue in one of two directions to Central Park. The first alternate alignment would be
north along Bouquet Canyon Road, while the second alternate direction would be east along Newhall
Ranch Road to the River Village development and then north to Central Park. This pipeline would
serve industrial and non-potable irrigation demands adjacent to the alignment. Anchor irrigation
customers would be Valencia High School, Valencia Heritage Park, Bridgeport Park and Central Park.
CEQA Analysis: CLWA, with the assistance of Meridian Consultants, prepared a draft Initial
Study/Mitigated Negative Declaration (IS/MND) for the Project. The IS/MND analyzed the potential
environmental impacts for the Project and concluded that with mitigation, there would be no significant
impacts. Mitigation measures needed to mitigate or avoid potentially significant impacts are included in
the IS/MND for the following environmental factors: Noise, aesthetic/visual, and tribal/cultural resources.
