Sunline Transit Agency

Sunline Transit Agency, a local government entity based in Thousand Palms, California, is a federal grant recipient operating fixed-route and paratransit bus services for the Coachella Valley region as a prime recipient under Federal Transit Administration programs, with no federal contracts but substantial formula and discretionary grant activity from the Department of Transportation.

Sunline's federal footprint is almost entirely concentrated with the Federal Transit Administration under CFDA 20.507 (Federal Transit Formula Grants) and CFDA 20.526 (Buses and Bus Facilities programs), accounting for 72 of 73 prime awards across the past several years. Recent prime grant work reflects the agency's capital modernization and zero-emission fleet transition strategy: a $29.8 million FY 2024 operating assistance award (July 24, 2025) supporting direct labor, materials, overhead, and consumables for fixed-route and paratransit operations in the Indio-Cathedral City urbanized area; a $10.32 million FY 2026 operating assistance award (March 12, 2026) covering operator salaries, fringe benefits, fuel, tires, and insurance through December 31, 2026; an $8.74 million project grant (August 22, 2025) under CFDA 20.526 to procure and deploy six hydrogen fuel cell electric buses into revenue service, replacing six aging compressed natural gas buses, with completion by May 31, 2028; a $3.35 million capital project grant (September 16, 2025) to design, procure, and construct a public liquid hydrogen fueling station at Sunline's Indio facility, with completion targeted for January 31, 2028; and two separate paratransit fleet modernization awards totaling $3.77 million combined to purchase fourteen replacement compressed natural gas paratransit buses for ADA-eligible passengers, with completions by August 31, 2027. Sunline also received a $16.6 million ARPA-funded operating assistance award (July 30, 2021) to support COVID-19 pandemic response and a $525,000 supplemental ARPA grant (April 3, 2023) for operations. The Department of Energy's Office of Energy Efficiency and Renewable Energy awarded Sunline a clean cities outreach and performance tracking cooperative agreement (April 1, 2023, CFDA 81.087) for hydrogen and clean-fuel education programming.

The agency acts as a direct recipient on all prime awards with no subrecipients named in most grant documents, demonstrating direct implementation of capital and operating projects. Sunline's sub-award activity is minimal, including pass-through arrangements where Sunline acts as an intermediary grantee: a December 16, 2024 sub-award to Arches H2 LLC for hydrogen refueling station development and thirteen fuel cell electric buses, and a June 17, 2024 sub-award notation related to California Department of Transportation work in Orange and Los Angeles counties. The source also lists several operating-assistance sub-awards (September 22, 2025; August 26, 2024; July 30, 2024) with minimal detail on subrecipient identity.

Seventeen awards face ultimate completion dates within the next twenty-four months, creating recompete exposure in FTA formula and discretionary programs. Activity has grown modestly — one award in 2022 to eight annually in 2024 and 2025 — with combined dollars obligated across all awards totaling $331.6 million. Sunline's grant work benefits transit-dependent populations in the Coachella Valley, with particular emphasis on low-income individuals, seniors, persons with disabilities, and residents of disadvantaged communities in Indio, Coachella, and Mecca ranked in the 90th to 95th percentile for air pollution burden per CalEnviroScreen 4.0.
