Planning commission reviews draft annexation ordinance as UGB expansion advances

Planning staff briefed the Sisters Planning Commission on a draft annexation ordinance during a workshop on Aug. 6, 2026, tying the new rules to the city’s proposed urban growth boundary (UGB) expansion and an upcoming area-plan process. Staff said the ordinance will move annexation provisions into the development code so petitions are reviewed against clear, consistent criteria rather than resolved through individual negotiations.

“Once the UGB is adopted and the area plan is complete, we want applicants to bring a master plan at the time of annexation — not a promise to deliver a plan later,” the planning staff member said during the presentation. Staff framed the ordinance as a way to make expectations explicit for utilities, transportation, parks and schools and to give developers enough direction on critical corridors and zoning during master planning.

Staff walked commissioners through procedural options, saying smaller, site-specific annexations would use a Type 3 (quasi‑judicial) review while larger or more complex annexations could use the Type 4 process that is not bound by typical 120‑day review timelines. The presentation also described an interface with county processes: proposed county code text amendments (Title 21) are being processed concurrently to ensure environmental and overlay protections carry into the UGB lands.

Commissioners asked clarifying questions about contiguity rules, master-plan exemptions and the timing of plan amendments for water, sewer and transportation. Staff said applicants may be permitted to initiate necessary amendments to city master plans if they seek to accelerate development, but those amendments would remain subject to city review.
