Weber County planning staff seeks tighter water-conservation rules, greater coordination with irrigation and culinary providers

Charlie, a Weber County planning office staff member, opened the Western Weber water-conservation meeting by asking participants to share policies and data and saying, “Just get it out there. We'll make sure that, the planning office takes these these ideas and and runs with it.” The meeting brought together irrigation-company representatives, developers and county staff to discuss possible amendments to the county general plan and code and to improve cooperation between culinary and secondary water suppliers.

The discussion focused on several county tools that staff said can be used to reduce outdoor water use: design review (Weber County Code Chapter 108), architectural/landscaping standards (Chapter 108-2), conditional-use review, development agreements and will-serve letters. Charlie said those tools allow the county to require developers to submit landscape architecture plans and hold developers to landscaping commitments in development agreements.

Why it matters: Western Weber is planning for significant growth while local water supplies and infrastructure are constrained. County staff and participants framed the discussion as an attempt to stretch existing supplies, limit evaporation from retention features and align developer expectations with available water and delivery systems.

Participants raised practical and legal constraints. County staff noted the requirement in one of the county’s water codes that any new well drilled to serve a subdivision must be pump-tested for 48 hours to prove yield before it is relied upon for a development. Several participants described the difference between an “availability” letter (which many developers currently obtain earlier in the process) and a formal “will-serve” commitment from a water provider. Multiple water providers and developers urged the county to require will-serve letters at the rezone stage, saying an availability letter alone can allow projects to advance without secured utilities.

Irrigation companies and culinary (treated) water providers discussed the technical and legal challenges of shifting water from secondary (often gravity-fed canal systems used for irrigation) into pressurized culinary systems for homes. Speakers noted irrigation bylaws and state law define processes for shareholders who want to move water out of an irrigation company; a recurring figure cited in the meeting was that irrigation companies often expect to retain roughly 20% of shares for in‑ditch delivery while allowing the remainder to be changed under a state change-of-use application.

Attendees debated infrastructure options. County staff and water providers said pressurizing gravity irrigation systems and building storage or treatment facilities would be costly but could allow some irrigation water to be treated and used for household needs, while still leaving a portion in the ditch for downstream rights holders. Participants warned that detention ponds and open retention basins increase evaporative losses; one participant said research shows detention ponds can lose roughly three quarters of stored water to evapotranspiration, reducing the amount that reaches reservoirs.

Several implementation and enforcement issues arose. The county’s ability to require landscape installation at occupancy depends on the permit process and inspection capacity; staff said enforcement would require coordination with building inspectors and clearer development-agreement language so landscaping commitments “run with the land.” The group discussed placing landscaping limits or watering allotments into deeds or development agreements so restrictions remain in perpetuity or for specified terms (one development agreement example discussed includes a 30-year term).

Funding and consolidation options also came up. Participants identified state and federal funding sources — including Department of Water Resources low-interest loans and Department of Agriculture programs — as potential supports for pressurization, treatment plants or oversized distribution mains. County staff said the planning office will draft a proposed approach to the group and reconvene for a follow-up meeting to discuss a written draft before taking code amendment steps.

Ending: County staff closed the meeting by asking the planning office to prepare a draft proposal and returning the group for another in-person review. Participants generally favored seeing a written proposal in advance and agreed to reconvene for a final discussion or to provide comments by email as appropriate.
