Portland Metro is unlike any other governmental entity in the United States. It is the only directly elected regional government with statutory land use authority, meaning its planning decisions bind the 24 cities and three counties within its jurisdiction, not as suggestions that local governments may choose to follow, but as enforceable regional requirements. For developers working in the Portland metropolitan area, Metro represents a regulatory layer with no equivalent anywhere else in the country, and understanding its authority is a prerequisite for competent development practice in the region.
What Metro Is and Where It Came From
Metro was created by Oregon voters in 1978 under a home rule charter that gave the regional government authority over the Urban Growth Boundary, regional transportation planning, and solid waste management. The charter has been amended several times since, most significantly in 1992 when voters approved a new charter that strengthened Metro’s land use planning authority and established the Metro Council, a six-member elected body representing districts within the tri-county area, plus an elected Metro President.
Metro’s jurisdiction covers Multnomah, Washington, and Clackamas counties in their entirety, including Portland, Gresham, Beaverton, Hillsboro, Lake Oswego, and the 20 other cities within the metro boundary. Metro does not govern cities outside the UGB; rural Multnomah, Washington, and Clackamas counties are governed directly by their respective county governments for land use purposes.
The Urban Growth Boundary: Metro’s Primary Land Use Tool
Metro’s most consequential land use authority is control over the Portland UGB. The UGB defines the outer boundary of urban development for the entire tri-county metro area, a single boundary managed by a single regional authority rather than separately by each of the 24 cities within it. This regional UGB management is unique among US metropolitan areas; in other states, each city manages its own growth boundary (if it has one at all), and regional coordination is advisory at best.
Metro reviews the UGB on a regular cycle, assessing whether land inside the boundary is sufficient to accommodate 20 years of projected population and employment growth. When the supply of buildable land inside the UGB is projected to be insufficient, Metro initiates a process to consider expanding the boundary, evaluating candidate sites, analyzing infrastructure costs, and assessing the impact on agricultural and resource lands outside the boundary.
UGB expansion decisions in Portland Metro are major planning events that involve extensive public process, Statewide Planning Goal compliance review, and often legal challenges from agricultural landowners, environmental groups, or cities that oppose the expansion. The most recent significant UGB expansion in the Portland area took years from initiation to completion. For developers, the practical implication is that land outside the UGB cannot be counted on to enter the development market on any predictable timeline.
Metro’s Functional Plan: The Titles That Govern Development
Metro’s authority extends beyond the UGB to a set of regulatory requirements called Metro’s Functional Plan, which cities and counties within Metro’s jurisdiction must incorporate into their local comprehensive plans and development regulations. The Functional Plan contains numbered Titles, each addressing a specific aspect of regional land use:
Title 1 (Requirements for Housing and Employment Accommodation). Requires cities to maintain sufficient land supply for housing and employment to meet Metro’s regional forecasts. Title 1 is the regional implementation mechanism for Oregon’s Goal 10 housing requirement, cities must demonstrate that their zoning allows development of needed housing types at sufficient densities. Developers can use Title 1 compliance data to identify cities that are falling short of their housing accommodation requirements and may be open to upzoning or density increases.
Title 6 (Central City, Regional Centers, Town Centers, and Corridors). Designates the regional hierarchy of centers and corridors where Metro expects concentrated development, the Central City (downtown Portland), regional centers (like Beaverton’s Round, Gresham’s downtown), town centers, and main street corridors. Title 6 directs cities to plan for higher densities and mixed-use development at these designated locations. Developers planning transit-oriented, mixed-use, or high-density residential projects should identify whether their target sites fall within Title 6 centers or corridors, because these designations typically correlate with more permissive zoning and stronger local political support for density.
Title 12 (Protection of Residential Neighborhoods). Establishes minimum density requirements for residential development in urban areas, requiring that new residential development in urban zones achieve at least a minimum number of units per acre. Title 12 is designed to prevent sprawling low-density development on infill sites that could otherwise be developed at urban densities.
Title 13 (Nature in Neighborhoods). Protects significant natural resources, streams, wetlands, wildlife habitat, within Metro’s jurisdiction through a regional natural resource inventory and protection program. Development on or adjacent to Title 13-inventoried natural resources requires impact assessment and, where impacts cannot be avoided, mitigation. Developers evaluating sites within the Metro boundary should check Title 13 mapping early in due diligence.
How Metro Review Affects Development Timelines
For most standard urban infill development, a multifamily project on an already-urbanized site within an established zoning designation, Metro review is not a separate step in the permitting process. The city’s local land use review incorporates Metro’s Functional Plan requirements, and compliance is verified as part of the city’s comprehensive plan acknowledgment.
Metro review becomes a direct issue for: UGB amendments (Metro reviews and approves); comprehensive plan amendments with regional significance that affect Metro-designated centers or corridors; and appeals of local land use decisions that raise issues of Metro Functional Plan compliance. The Land Use Board of Appeals (LUBA), Oregon’s specialized appellate body for land use decisions, hears appeals of local and Metro land use decisions and applies statewide planning goal standards in its review.
Developers on large or complex Portland metro projects who are proposing development at densities or uses that push against local zoning limits should evaluate early whether their project has regional significance that might trigger Metro review or appeal, and should engage land use counsel with Metro practice experience before the project is too far along to accommodate the time that Metro review or LUBA appeal might require.
