Chino Hills adopts 2025 Urban Water Management Plan and Water Supply Contingency Plan

At a public hearing, the City Council adopted a resolution approving the City of Chino Hills' 2025 Urban Water Management Plan and the companion Water Supply Contingency Plan and directed staff to submit the documents to the California Department of Water Resources.

Water Manager Mark Wiley told the council the Urban Water Management Plan is a five-year update that complies with the Urban Water Management Plan Act and SBX7-7 and cited California Water Code section 10631. He noted that Chino Hills exceeded the 2020 conservation target (the city’s 2020 per-capita use was 148 gallons per capita per day and is currently about 138 gpcd).

"This serves as the operating manual to prevent catastrophic service disruptions through proactive rather than reactive mitigation of shortages," Wiley said, noting the plan was available online and must be submitted to the Department of Water Resources.

Council closed the public hearing, received no public comment on the item, and approved the resolution by a unanimous vote.

What this means: the adopted plans codify the city's demand-management practices (tiered rates, metering, multi-stage conservation ordinance and outreach) and provide a formal shortage-response guide for staff to use during drought or supply interruptions. Staff said the contingency plan can be amended as conditions change and will be available publicly.

Next steps: staff will file the adopted plans with the Department of Water Resources and continue public outreach about conservation programs and the new water-treatment redundancy provided by the recently completed TCP facility.
