TITLE
Recommendation to authorize City Manager, or designee, to execute a Water Discharge and License Agreement, including any other necessary documents or subsequent amendments, with the Water Replenishment District, a public agency that operates the Leo J.

As part of the water treatment process, LVL is currently in need of a site to discharge backflushed water from the LVL’s injection well. In late 2022, WRD approached the City’s Parks, Recreation and Marine Department to discuss the potential use of the City’s undeveloped site north of LVL’s facility to discharge their backflushed water into the City’s existing storm drain system.
The City is in the design phase of the El Dorado Regional Stormwater Capture Project (Project) which will entail the development of an expansive 10.3-acre-foot treatment vegetated pond system consisting of a series of three hydraulically connected pools located at the open parcel north of the LVL and South of Willow Street (Attachment A). Both dry and wet weather flows from the Artesia-Norwalk Drain will be intercepted, treated, and partially captured prior to discharge to the Coyote Creek.
