Communities in Motion 2050 and Local Land Use Planning Integration

Communities in Motion 2050 (CIM 2050) functions as the regional long-range transportation plan for Ada and Canyon Counties, developed by the Community Planning Association of Southwest Idaho (COMPASS). It integrates with local comprehensive land use plans by offering a shared regional framework and unified data forecasts—covering population, housing, and jobs—that help local governments synchronize their individual development goals with regional infrastructure requirements.

The short answer

Communities in Motion 2050 (CIM 2050) integrates with local comprehensive plans by providing a shared, regional data foundation for growth. Because the Treasure Valley is a highly connected region, COMPASS develops this long-range transportation plan to model how land use changes—such as new residential subdivisions or commercial centers—impact regional traffic, safety, and economic vitality. Local jurisdictions, including cities and counties, use the CIM 2050 'preferred growth scenario' as a guidance tool to ensure their individual comprehensive plans align with regional infrastructure capacity and long-term quality-of-life goals.

Key facts

Responsible Agency
COMPASS (Community Planning Association of Southwest Idaho) is the federally designated Metropolitan Planning Organization (MPO) responsible for the Treasure Valley's regional planning.
Primary Integration Mechanism
CIM 2050 establishes a 'preferred growth scenario' and regional data forecasts (demographics, jobs, and housing) that member agencies incorporate into their local comprehensive plans.
Governing Structure
COMPASS is a voluntary, member-based association governed by a Board of Directors comprised of local elected officials, ensuring alignment between regional strategies and local priorities.

Aligning Regional Strategy with Local Zoning

Integration occurs primarily through the exchange of data and goals. While individual cities and counties maintain the legal authority to enact their own zoning ordinances, they utilize the regional forecasts produced by COMPASS to inform their planning decisions.

By utilizing a common dataset for projected population and housing growth, local governments can better anticipate the impacts of new developments on shared infrastructure like roads, public transit corridors, and utilities.

  • CIM 2050 serves as a roadmap that links land use decisions directly to transportation investment.
  • It provides a 'preferred growth scenario' that encourages more compact, efficient development patterns to reduce traffic congestion.
  • Member agencies voluntarily incorporate these regional priorities to ensure their local plans remain cohesive with their neighboring jurisdictions.

The Role of the MPO Structure

The success of this integration relies on the governance structure of COMPASS. As a Metropolitan Planning Organization (MPO) composed of local mayors, city council members, and county commissioners, the organization is built to facilitate collaboration.

This structure ensures that the people responsible for approving local land use and zoning are also the ones crafting the regional transportation vision. This overlap helps minimize discrepancies between a city’s individual growth plans and the regional transportation network.

Limitations of Regional Planning

It is important to understand that CIM 2050 is a guiding framework, not a regulatory mandate. COMPASS does not have the authority to override local zoning decisions or land use approvals made by individual cities or counties.

Because COMPASS is a voluntary association, the degree of integration can vary depending on the jurisdiction. Some municipalities may prioritize regional alignment more heavily than others, meaning that regional goals are often achieved through cooperation and shared incentives rather than top-down enforcement.

Common questions

What is the difference between a comprehensive plan and CIM 2050?

A local comprehensive plan is a regulatory, long-term policy document created by a specific city or county to guide its own land use, zoning, and public services. CIM 2050 is a regional-scale plan developed by COMPASS that focuses on the transportation and development patterns affecting the entire two-county Treasure Valley area.

Does CIM 2050 dictate local zoning ordinances?

No. CIM 2050 provides a regional framework and growth projections. While these projections inform local planning, the actual authority to enact, modify, or enforce zoning ordinances and specific land use decisions remains with the local city or county government.
