1.0 Introduction

this pipeline. Anchor irrigation customers would be Valencia High School, Valencia Heritage Park,
Bridgeport Park, and Central Park.

The 24-inch transmission pipeline would include isolation valves, air release valves, blow-off valves,

recycled water service connections, and all other necessary appurtenances. All pipelines would be
polyvinyl chloride (PVC) or ductile iron pipe (DIP), and would be installed using typical open-trench cut
and cover method, with a minimum cover of approximately five (5) feet with roadway pavement and
native soils above the pipeline. Bedding and backfill material would be utilized to fill around and below
the proposed recycled water pipeline. In addition to the recycled water pipeline, a pressure-release valve
and wharf heads would be installed aboveground along the proposed alignment. The main transmission
line would consist of 24-inch pipeline, with smaller 16- and 12-inch transmission pipelines where needed.

Distribution pipelines would be 6 to 8 inches.

The State CEQA Guidelines require that the decision-making body of the Lead Agency consider the proposed
IS together with any comments received during the public review process prior to approving a project.

Two comment letters were received regarding the Draft IS. One letter was from the State of California
Governor’s Office of Planning and Research, State Clearinghouse, on October 24, 2017. The comment
notes that only one State agency, the California State Water Resources Control Board (SWRCB), submitted
comments on the Draft IS, and that CLWA has complied with the State Clearinghouse review requirements
for draft environmental documents, pursuant to CEQA.
