Enterprise revenue requirements and allocates cost equitably across all customer
classes.
•Prop. 218 allow rates models to be adopted up-to five year increments.
•Rate methodology follows AWWA M1 Principals of Water Rates, Fees, and
Charges.
Proposition 218
•1996, California voters passed Proposition 218, the “Right to Vote on Taxes
Act”, limits the methods by which local governments can create or increase
taxes, fees and charges.
•Requires individual notices be mailed to affected property owners, and requires a
formal protest hearing prior to increasing rates.

Effects of PFAS & Supply Shift
•In 2020 the State Water Board
lowered the Response Level for Per
–and Polyfluorinated Substances
(PFAS) in drinking water
•5 groundwater wells were shut
down that were operating near the
new Response Level

Water Supply Shift
10
What Changed:
•5 groundwater wells were taken offline due to changes in State PFAS regulations.
•Operational costs approx. $3M/year higher than adopted rate model.
•Largely due to purchasing more imported water, but all costs have increased, energy, equipment, chemicals, etc.
What is the Plan?
•The City has partnered with Orange
County Water District to construct a
new PFAS Treatment Plant
•Anticipated operational in 2024.
This site will remove PFAS from
groundwater wells
•Allows the City to continue
providing high-quality,reliable
drinking water from own sources

Next Steps

Service Rate Study sets the maximum rate increase of 9% for each
operating year.
•Staff recommends an annual update and presentation at a publicly
noticed meeting to provide a comprehensive update on the
performance of the Water Enterprise.
•In the event that the Enterprise out preforms the estimates outlined
in the rate model, the City Council may consider and potentially
adopt a lower rate for the following year.
