Los Angeles County Long Range Transportation Plan

The Los Angeles County Long Range Transportation Plan is a strategic regional blueprint developed by the Los Angeles County Metropolitan Transportation Authority (Metro), in coordination with the SCAG, City of Los Angeles, Los Angeles County Board of Supervisors, and municipal partners. It synthesizes infrastructure programs from Measure M, the Federal Transit Administration, the CalSTA, and other funding sources to guide investments across the county multimodal network.

Overview

The Plan situates long‑term investment within the context of regional growth patterns derived from California Department of Finance projections, market signals identified by the LAEDC, and land‑use scenarios from SCAG planning. It integrates corridors served by Metro Rail, Metrolink, Pacific Surfliner, and major facilities such as Los Angeles International Airport and Port of Los Angeles. The Plan references statutory frameworks including the FAST Act and SB 1 to align with statewide priorities.

Goals and Objectives

Primary goals reflect statewide and regional mandates: improving mobility for riders of Metro Bus and Metro Rapid, expanding rail connectivity exemplified by projects like the Purple Line Extension and Crenshaw/LAX Line, enhancing goods movement for the Port of Los AngelesPort of Long Beach complex, and reducing greenhouse gases consistent with CARB targets. Objectives include integrating transit-oriented development consistent with Transit-Oriented Development (TOD) best practices seen in Koreatown, Los Angeles and coordinating with Los Angeles Unified School District site planning, while meeting safety mandates from the NHTSA and resilience priorities advocated by the Cal OES.

Planning Process and Stakeholders

The planning process convenes elected officials from the Los Angeles County Board of Supervisors, city managers from jurisdictions like City of Long Beach, City of Pasadena, and City of Santa Monica, agency staff from Caltrans District 7, labor representatives from Amalgamated Transit Union locals, freight stakeholders including UPS and Union Pacific Railroad, and community groups such as LAANE and the NRDC. Technical input derives from consultants familiar with tools like the Regional Transportation Plan/Sustainable Communities Strategy travel demand models and the EPA benefit‑cost frameworks. Public outreach leverages town halls in neighborhoods like Watts, Los Angeles and South Gate, California and digital engagement via agency portals.

Key Components and Projects

The Plan catalogs capital programs: expansion of the A Line and E Line, completion of the Regional Connector, conversion of bus fleets to zero‑emission vehicles consistent with CARB rules, and arterial improvements on corridors such as Wilshire Boulevard and Pacific Coast Highway. Freight initiatives include grade separations on Great Northern Corridor and investments near the I‑710 and I‑10. Active transportation projects reference networks in Griffith Park, Santa Monica Mountains National Recreation Area, and bikeway plans in Culver City. Integration with intercity services prioritizes connectivity to Los Angeles Union Station, Bob Hope Airport, and the California High-Speed Rail Authority initial segments.

Funding and Implementation Strategies

Funding strategies combine local ballot measures like Measure M and Measure R, state allocations from SB 1, and federal programs under the Infrastructure Investment and Jobs Act. Implementation phasing coordinates with capital programs funded by the FTA Capital Investment Grants and tax‑increment financing tools used in conjunction with Community Redevelopment Agency of Los Angeles legacy projects. Public–private partnerships involve firms such as AECOM, Skanska, and Fluor Corporation for delivery, while grant management aligns with Metropolitan Transportation Commission and FHWA standards.

Performance Metrics and Monitoring

Performance monitoring employs metrics drawn from CARB emission inventories, Federal Transit Administration ridership statistics, travel time reliability measures associated with the TTI Urban Mobility Report, and safety indicators tracked by the NHTSA. Progress reporting uses a dashboard approach similar to Los Angeles County Department of Public Health dashboards and quarterly board briefings to the Metro Board of Directors. Equity and mode‑shift outcomes are benchmarked against SCAG targets and California Strategic Growth Council indicators.

Environmental Justice and Equity Considerations

Equity analysis follows guidance from the California Environmental Quality Act implementation by California Natural Resources Agency and federal Environmental Protection Agency environmental justice frameworks, prioritizing investments in Disadvantaged Communities identified by CalEnviroScreen. The Plan addresses air quality burdens near the I‑710 Corridor Project and emissions hotspots adjacent to the Port of Los Angeles and coordinates mitigation with SCAQMD programs. Community benefits agreements partner with labor groups such as the Service Employees International Union and local nonprofits including Coalition for Responsible Community Development to ensure workforce development, affordable housing near stations, and protections for neighborhoods like Boyle Heights and Vernon, California.
