Oregon
Summary
Oregon delegates the actual zoning power to cities (ORS Chapter 227) and counties (ORS Chapter 215): ORS 227.215(2) authorizes a city to "plan and otherwise encourage and regulate the development of land" and to divide itself into districts, while ORS 215.050(1) directs the county governing body to "adopt and may from time to time revise a comprehensive plan and zoning, subdivision and other ordinances applicable to all of the land in the county." What makes Oregon distinctive is that this delegated zoning authority operates inside a mandatory statewide land use planning framework: under ORS Chapter 197, the Land Conservation and Development Commission (LCDC) adopts binding statewide planning goals, and all local zoning and land use regulations must implement an acknowledged comprehensive plan that conforms to those goals (ORS 215.050(2) requires county ordinances be "designed to implement the adopted county comprehensive plan"). Thus zoning power is held and exercised locally by counties and municipalities, but it is supervised, constrained, and reviewable at the state level rather than left fully to local discretion. Confidence is high; the operative city and county grant-of-power sections were confirmed verbatim from Oregon public.law, with the county text cross-checked at the official Oregon Legislature site.

Verification

Verified all three components. (a) Real, current statutes: ORS 227.215, 215.050, and Chapter 197 are all real, in-force Oregon Revised Statutes. Confirmed via oregon.public.law and the official Oregon Legislature site (oregonlegislature.gov/bills_laws/ors/ors215.html). (b) Genuine zoning enabling authority: - ORS 227.215(2) verbatim confirmed: "A city may plan and otherwise encourage and regulate the development of land..." This is the city land development/zoning grant. (Note: the explicit "divide the city into districts" language sits in 227.215(4), not (2); the claim references districting generally without misattributing the subsection, so this is immaterial.) - ORS 215.050(1) verbatim confirmed against BOTH oregon.public.law and the official Oregon Legislature site: "...the county governing body shall adopt and may from time to time revise a comprehensive plan and zoning, subdivision and other ordinances applicable to all of the land in the county." (Full text begins "Except as provided in ORS 527.722.") This is the county zoning grant. - ORS 215.050(2) verbatim confirmed: ordinances "shall be designed to implement the adopted county comprehensive plan." - ORS Chapter 197 confirmed as the statewide land use planning program: SB 100 (1973) created LCDC; ORS 197 directs LCDC to adopt binding statewide planning goals (19 goals); every city and county must adopt comprehensive plans and implementing zoning that comply with those goals. (c) Authority model accurate: county_and_municipal (state-supervised statewide planning) correctly captures Oregon's distinctive structure — zoning power is delegated to and exercised by cities (Ch. 227) and counties (Ch. 215), but constrained by mandatory acknowledged comprehensive plans conforming to LCDC's statewide goals (Ch. 197). Citation, title, summary, and authority_model are all accurate.
