County updates subdivision approval rules to comply with 2023 SB 174

County planning staff presented rule changes required by 2023 SB 174 and asked the commission to adopt clarifying amendments to the subdivision-approval ordinance.

Staff said one amendment removes a previously inserted 40% minimum for irrigation‑water requirements and replaces it with a more flexible process allowing applicants to propose reductions with supporting evidence. A second amendment removes a commission approval step for one category of irrigation‑water reduction because the statute removed legislative-body approval for that action.

County staff told commissioners the ordinance language has been used by the planning commission and that an implementation date had been managed during earlier planning-commission action. A commissioner moved and the commission approved the amendments.

Why it matters: The changes are staff- and statute-driven updates to ensure county code matches state law; they change how irrigation‑water reductions are reviewed and remove a commission approval requirement where state law no longer permits it.

Next steps: Staff will publish the amended ordinance language and continue using the revised procedures for subdivision review.
