Near-Term Action - Comprehensive ten-year review of the TransNet program

In 1987, San Diego County residents approved the original TransNet program, a half-cent sales tax to fund a variety of transportation projects throughout San Diego County. The program ended in 2008 after 20 years and raised $3.3 billion to upgrade the region’s highways, improve local roads, extend trolley and commuter rail lines, and create bike paths that support walkable communities. The TransNet Extension, approved by voters in 2004, extended the TransNet program to 2048 for transit, highway, local road, bikeways and walking paths, smart growth, and habitat preservation, as well as new Rapid transit lines and rail service expansion projects to help improve mobility within the region.

As part of the TransNet Extension, the Ordinance mandates the completion of a ten-year comprehensive review of all projects and programs implemented under the Expenditure Plan “to evaluate the performance of the overall program over the previous ten years and to make revisions to the Expenditure Plan to improve its performance over the subsequent ten years.” The first ten-year review is slated to be conducted in Fiscal Year (FY) 2019, with additional reviews planned for FY 2029 and FY 2039. While the Independent Taxpayer Oversight Committee (ITOC), a committee established through the Ordinance to provide an enhanced level of accountability for expenditures made under the Expenditure Plan, will provide recommendations for program improvement, the review will be conducted by the SANDAG Board of Directors acting as the San Diego County Regional Transportation Commission in accordance with Ordinance provisions.

The TransNet   ten-year review kicked off in summer 2017 and is being conducted concurrently with development of the 2019 Regional Plan in order to more efficiently accomplish the comprehensive review and better inform the next Regional Plan. The TransNet  Extension Ordinance: 10-Year Look-Back, presented to the SANDAG Board of Directors in January 2018, assessed performance of the overall TransNet  program to date. The “look ahead” kicked off in early 2018 and will use results from the “look back” as a basis to consider potential revisions to improve performance of the TransNet   program going forward.
