Local Bridge Seismic Safety Retrofit Program
For general information regarding developing federal-aid and state funded local projects please refer to "Local Assistance Procedures Manual".
Local bridge retrofit projects developed under the Seismic Safety Retrofit Program (as defined below) are funded with 80% Federal Funds and 20% Local match. Reimbursable work include consultant selection, seismic analysis leading to strategy, environmental, right of way, PS&E, construction, construction engineering and local agency overhead.
This program is limited to those bridges that are determined to be Category 1, bridges that may collapse in a seismic event and potentially threaten public safety. Eligibility of a bridge is decided by a series of screening processes.
Three lead agencies were designated in the program as follows:
Los Angeles County:
lead agency for local bridges in Los Angeles County.
Santa Clara County:
lead agency for local bridges located within the unincorporated portion of the county.
lead agency for all local bridges in California, except Los Angeles County and the unincorporated portion of Santa Clara County.
A lead agency inspects all publicly owned bridges for which it is the lead agency and assesses the need for seismic retrofit work. For each bridge which is determined that seismic structural deficiencies exist, the lead agency or the bridge-owning agency then develops a retrofit project. Projects are developed using the information gathered during the screening phase and other criteria established by the lead agencies.
