TIP Amendment 2021-10 and Transportation Air Quality Conformity Analysis

The Metropolitan Transportation Commission has released the proposed Final Transportation Improvement Program (TIP) Amendment 2021-10 and the proposed Final Transportation-Air Quality Conformity Analysis for Plan Bay Area 2050 and the Amended 2021 TIP.  Amendment 2021-10 serves to conform the 2021 TIP to Plan Bay Area 2050 and the Transportation-Air Quality Conformity Analysis demonstrates that the amended TIP is consistent with ("conform to") the federal air quality plan known as the State Implementation Plan (SIP).  These documents are scheduled to be reviewed by the MTC Planning Committee on October 8, 2021.  For more information, please visit:

The TIP lists projects or programs that have a federal interest — meaning projects or programs for which federal funds or actions by federal agencies are anticipated — along with locally and state-funded projects that are regionally significant.

MTC encourages public comment on the TIP and on any proposed revisions.

Adoption & Approval

MTC must adopt a new TIP at least once every four years, and state statute requires the Bay Area to update its TIP every two years.

The Federal Highway Administration and the Federal Transit Administration must approve the TIP.

TIP Revisions

The TIP is frequently changed after adoption, with projects added or deleted; accelerated or delayed; re-scoped or re-phased.

What’s Included in the TIP?

The TIP lists transportation projects and programs for which an action by a federal agency is expected — not just funding.

The TIP also includes major regional projects (those that change travel patterns over a relatively large geographic area) funded with local or state dollars, even those with no federal money.

The TIP covers all modes — transit, highways, bridges, local streets and roads, bicycle, pedestrian and freight movement projects.

Costs & Schedules

The TIP shows estimated project costs and schedules.

Project funding in the four year TIP period must be committed or reasonably expected to be available.

Inclusion in the TIP does not guarantee that construction on a project will begin; and does not represent an allocation or obligation of funds.
