AI Contract Overview

The County of Santa Cruz's Department of Community Development & Infrastructure is inviting qualified consulting firms to submit proposals for professional civil engineering and environmental services to support the replacement of the Larkspur Street bridge over the San Lorenzo River (Bridge No. 36C-0068). The existing structure, built in 1957, is a 133-foot-long, three-span bridge featuring a single narrow travel lane and timber walkways, with critical issues including scour vulnerability, poor visibility on the eastern approach, and failure to meet current design standards. The project involves demolishing the current bridge and constructing a new two-lane, single-span, cast-in-place post-tensioned concrete box girder bridge designed to meet contemporary safety, seismic, and scour requirements per AASHTO and Caltrans standards. This federally funded project—coordinated through the Highway Bridge Program in partnership with the Federal Highway Administration, Caltrans, and the County—requires consultants to comply with Caltrans Local Assistance Procedures Manual and all related regulations. Proposals must be submitted by June 18, 2026, with the full solicitation accessible via the County’s OpenGov Procurement portal. The project underscores the importance of addressing structural deficiencies, enhancing traffic safety, and supporting critical utilities currently carried by the bridge, including water, gas, telecommunication, and power lines. The County’s contacts for this solicitation are Amber Myer, Civil Engineer, and Rosa Ortiz, Assistant Departmental Administrative Analyst, who can provide additional information regarding the proposal process. The engagement represents a critical infrastructure improvement aimed at ensuring long-term durability and compliance with modern engineering standards for a key transportation link in Santa Cruz County.

Full Description

The County of Santa Cruz, Department of Community Development & Infrastructure is seeking proposals from qualified consultants for Professional Civil Engineering and Environmental Services for the Larkspur Street over San Lorenzo River Bridge Replacement Project (Bridge No. 36C-0068) in Santa Cruz County. The existing bridge, constructed in 1957, is a 133-foot-long, three span, precast, prestressed four girder bridge on two reinforced concrete pier walls with spread footings and reinforced seat abutments. With a total width of 15' 4", it provides a single 12' 2" travel lane with concrete curbs and timber railings on both sides of the structure. A narrow timber walkway is located on the downstream side of the deck. The bridge piers are considered to be scour critical with exposed spread footings and undermining. There is a sharp turn on the eastern approach roadway with poor site visibility. The bridge currently supports suspended water and gas lines, while telecommunication and power lines run directly overhead. The existing bridge does not meet current design standards. The proposed project would include replacing and demolishing the existing structurally obsolete bridge with a two-lane, single span, cast-in-place, post tensioned concrete box girder bridge that would be designed to meet current safety, seismic, and scour requirements in accordance with current American Association of State Highway and Transportation Officials (AASHTO) or Caltrans design standards. The bridge is listed in the Highway Bridge Program (HBP) and will be funded in part through the Federal Highway Administration (FHWA) in cooperation with the California Department of Transportation (Caltrans) and the County. Consulting firm services must comply with the latest requirements of the Caltrans Local Assistance Procedures Manual (LAPM), Federal, State, and local regulations. This RFP, and any future Addenda, if issued, will be posted on the OpenGov Procurement website at https://procurement.opengov.com/portal/santacruzcounty .
