Do you support increasing local taxes to prevent public transit service cuts in your area?

The Metropolitan Transit System has proposed cutting one-third of its bus routes and reducing service on four trolley lines to address long-term financial gaps. The agency projects an annual budget deficit of up to $150 million by the 2030 fiscal year.

Why it matters

Rising operational costs have created a significant budget deficit that existing fare hikes cannot resolve, forcing a shift in how transit service is delivered. Local households that rely on public transit for commuting or access to key areas may face reduced mobility options.

The agency is considering the elimination of one-third of all bus routes and reduced service on four trolley lines. These proposals respond to a projected $150 million annual budget deficit expected by the 2030 fiscal year.

The players

Metropolitan Transit System

The agency providing public bus and trolley transportation services throughout San Diego.

The details

The Metropolitan Transit System is implementing a financial sustainability strategy to manage its mounting structural deficit. These proposals target widespread service areas including Sea World, Cabrillo Monument, Mission Hills, and Tierra Santa. Households should plan for a higher cost of transit usage, as additional fare increases are already scheduled to begin in October 2026.

October 2026: Fare increases begin for riders.
November or December 2026: MTS presents detailed plans for service adjustments.
2028: Potential vote for a sales tax hike to support transit funding.
2030: Target fiscal year for the projected $150 million annual deficit.

Money Landscape

This move follows a broader pattern of transit agencies balancing aging infrastructure costs against slowing revenue growth. It sits within the agency's effort to reconcile its long-term budget projections ahead of the 2030 fiscal year.

Commuters should anticipate higher out-of-pocket costs starting in October 2026 due to previously scheduled fare increases. Households that rely on specific routes in affected areas should begin reviewing alternative transportation options in their monthly budget.

The takeaway

The projected budget deficit signals a period of significant change for public transit accessibility in San Diego. Residents should review the upcoming detailed plans in late 2026 to understand how specific route changes might impact their daily commute costs.

What happens next

MTS will release specific service change proposals in November or December 2026. Voters in San Diego may also see a potential sales tax hike for transit funding on the ballot in 2028.
