InSAR results indicated no detectable inelastic subsidence; Piru showed elastic movement likely tied to reservoir releases. DBS&A reviewed a draft three-part approach for subsidence minimum thresholds and monitoring; Board received the presentation and discussed refinements, with comments due Sept. 25. UWCD projected ~100,000 AF diverted to the Oxnard Plain this water year vs. ~80,000 AF use.
Staff reported that Lake Piru is being drawn down to capture expected El Niño storm inflows this winter, with releases ramping up through fall. Groundwater in the Fillmore Basin remains near historic highs, though surface conditions are dry. The executive director announced he will retire from UWCD on Nov. 6, 2026, and the board discussed addressing the transition, possibly with a subcommittee, at a future meeting.
Ongoing concerns were reported about the Chiquita Canyon landfill, where a pyrolysis reaction could discharge leachate to the Santa Clara River, prompting new surface-water sampling. 82,000 acre-feet recharged into Oxnard basins and Port Hueneme by United Water. Omykiss were confirmed in Lost Creek via eDNA and observation, and long-term monitoring was discussed. DBS&A flagged Prop 4 funding ($368M) with no cost share and early-2027 applications.
