Research notes
Every Oregon city has a legally-defined Urban Growth Boundary separating urbanizable from rural land. Expansions require a demonstrated 20-year land need, follow strict priority order (exception areas first, then lower-value farmland), and are reviewed by DLCD and appealable to LUBA. Portland Metro has its own regional UGB managed by Metro under ORS 268. SB 1537 (2024) added a streamlined housing-focused UGB expansion pathway. Cities cannot annex or rezone land outside the UGB except per state procedures.
