RECOMMENDATION
Recommendation
It is recommended that the City Council adopt a resolution approving Program Supplemental Agreement No. F028 Revision 2 with the State of California for the Bridge Preventive Maintenance Program (Project No. st1703) and authorizing the approval of Budget Amendment Number 26.020 in the amount of $196,205 with a local match of $25,421 from Infrastructure Reserves.
Body
BACKGROUND/DISCUSSION
The City of South San Francisco (“City”) has an ongoing Bridge Preventive Maintenance Program (BPMP) for the sixteen (16) vehicle bridges that are under the California Department of Transportation (Caltrans) Bridge Inspection Program. The BPMP was created to help local agencies extend the life of their bridges by performing certain activities that have been preapproved by the Federal Highway Administration.
The Bridge Preventive Maintenance Program Goals are to:
1. Maintain the existing inventory of bridges in a structurally safe and serviceable condition.
2. Correct minor structural deficiencies early in a bridge's life, rather than wait until a bridge has major problems requiring costly rehabilitation, reconstruction, or replacement.
3. Extend the service lives of existing bridges.
4. Make efficient use of limited resources.
Caltrans inspects the bridges every two years and submits its findings to the City. City staff determines the appropriate actions based upon the reports and Caltrans work recommendations.
A summary of the recent bridge rehabilitation history and planned projects are outlined in the following table:

Thirteen (13) of the 16 City bridges under the Caltrans Bridge Inspection Program have or will be rehabilitated.
Program Supplemental Agreement No. F028 Revision 2
On August 28, 2025, the City received the Program Supplemental Agreement (PSA) No. F028 Revision 2 from Caltrans authorizing Preliminary Engineering funding for the nine (9) bridges in an amount of $196,205 for additional scope of work. The nine bridges had to provide habitat summaries on the existence of additional endangered species and how habitat mitigation measures would be handled during the construction phase. It required extensive additional field surveys to assess animal habitats for each bridge of which the prior funding was insufficient to cover. A final habitat report was provided, which included a plan to lessen habitat disruptions during construction.

The administration of state and federally funded local transportation projects is carried out by the benefiting agencies through the Caltrans Local Assistance Program. The City of South San Francisco has general authority as an administering agency; however, project-specific supplemental agreements are required for individual projects. The program supplement agreements allow for the reimbursement of project development costs. Program Supplement Agreement No. F028 Revision 2 authorizes Federal funding in the amount of $196,205 for preliminary engineering. The City’s matching fund for preliminary engineering is estimated at $25,421 from Infrastructure Reserves. And in conjunction with the prior local match of $14,911 it brings the total project cost for preliminary engineering to the amount of $236,537.
FISCAL IMPACT
There is a local match of $25,421 that will be required. The following table summarizes the revised project funding:
|
General Fund |
$250,000 |
|
Infrastructure Reserves |
$380,000 |
|
Grant HBP - PSA #28 |
$115,089 |
|
Grant HBP - PSA #28 Rev 2 |
$196,205 |
|
Local Match (total of both PSAs) |
$ 40,332 |
|
Amended Total Project Budget |
$981,626 |
As a standard condition of the PSA, the City agrees that any cost increase would be funded by the City. Should higher designer fee estimates be received, the City will be responsible for funding the shortfall to construct and deliver the project.
RELATIONSHIP TO STRATEGIC PLAN
Approval of this action will contribute to the City’s Strategic Plan outcome of improved Quality of Life by improving traffic safety and experience.
CONCLUSION
Staff recommends that the City Council adopt a resolution approving Program Supplemental Agreement No. F028 Revision 2 with the State of California for the Bridge Preventive Maintenance Program (Project No. st1703) and authorizing the approval of Budget Amendment Number 26.020 in the amount of $196,205 with a local match of $25,421 from the Infrastructure Reserves.
