Carpinteria Valley Water District weighs placing CAP capital charges on property tax bills or water bills

Carpinteria Valley Water District directors spent the bulk of their meeting reviewing two distinct ways to collect capital costs for the proposed CAP project and the separate question of an impact fee for future development.

A consultant and staff presenter summarized the two primary options: place a parcel-based charge on the property tax roll or add a fixed charge to customers’ monthly water bills. "We can either recover CAP costs through property tax bills," the presenter said, noting the tax-roll approach links the charge to "who is really the long-term beneficiary" — property owners — and may avoid short-term rate shock for monthly bill payers.

The board heard a list of technical obstacles to using the tax roll. Staff flagged cases where meters do not align with parcels — such as master-metered condominiums, meters that serve multiple parcels for agricultural accounts, and parcels with exemptions (for example mobile-home park tax exemptions) or missing owner records. The presenter recommended using county APN data to adjust for exemptions, a dataset that already exists for irrigated acreage and could be repurposed to allocate charges for split-meter ag accounts.

Using a condominium complex as an example, staff estimated charges: a 6-inch meter apportioned across 139 units would amount to roughly $173 per unit in the presenter’s example (about a 2.6% increase on a median unit tax bill). For master-metered mobile-home parks, staff estimated a per-residence pass-through could be small (an example calculation showed roughly $41 per unit). Staff emphasized the need to create and maintain a GIS layer and to reconcile parcel-record anomalies before any tax-roll approach could be implemented.

Directors debated the equity and transparency trade-offs. One director argued that if the CAP project primarily benefits users, the cost should appear on the monthly bill so customers see the charge directly; another stressed that property owners gain long-term value from a secure water supply and that the tax-roll nexus is philosophically defensible. Several directors raised concerns about renters bearing costs that are billed to property owners, underscoring that outreach and clear communication would be needed regardless of the method chosen. "If it's something so great and beneficial, then I feel like we should be able to easily justify it being on our monthly bill," one director said, while others pushed for additional outreach and data work to fairly assign charges.

The presentation also described the water-bill alternative. Staff warned that adding another fixed charge to monthly bills could further reduce the share of variable charges that reward conservation, and could increase customer confusion given the bill’s existing complexity. Preliminary illustrative numbers were shared showing multi-year bill trajectories under one assumed scenario; staff said definitive rates would require a formal cost-of-service study.

The board was also briefed on schedule and next steps: staff plans to gather public input via an April bill insert and online comment form, complete data preparation over the summer and fall, and return with impact and distribution analyses. Directors asked staff to bring a more detailed impact comparison and to identify tenant-versus-owner exposure for the next meeting, when the board may be asked for directional guidance rather than final action.

On the related topic of an impact fee for new development, staff explained that an impact fee (a capacity charge) can be structured either using CAP as the underlying project (allowing a per-acre-foot charge tied to the project’s cost buckets including capital, debt and potentially O&M) or using alternative water-supply strategies (supplemental purchases, banking), which would require different cost estimates. The board discussed whether to include historical O&M in the fee base (staff said impact fees typically recover capital but could include an O&M share if the board deems it appropriate) and whether to use the existing Capital Cost Recovery Fee (meter-size basis) or an impact-fee method tied to acre-feet of intensification (more precise but administratively heavier).

Staff said the intensification rule would typically be triggered when a development requires a new meter; at that point a CCRF or impact fee could apply. The presenter noted legal and fiscal constraints for impact fees: funds must be segregated, used only for the specified purpose, and committed to a project within five years of receipt. The board directed staff to include additional impact analyses and to return in two weeks with more detailed options.

What’s next: staff will gather the April public-comments and the FM3 survey results, finish data reconciliation (meter-to-parcel linkages, exemptions, and GIS layers), and present clearer cost comparisons and a recommended implementation pathway at upcoming meetings. The district is targeting preparation this summer/fall so a final proposal could be considered in a Prop 218-style process next spring.
