Stockton Bridge Debris Mitigation Design

The Department of Public Works for the City of Capitola is currently advertising for proposals for Design Services the following project:

Stockton Bridge Debris Mitigation

General work description:

The Stockton Avenue Bridge, constructed in 1934, is a beam bridge with three openings and two support piers. It spans Soquel Creek and is the furthest downstream bridge of the Creek. Soquel Creek is prone to large woody debris, which historically causes flooding by blocking bridges. Unlike the upstream bridges at Soquel Drive and Highway 1, the Stockton Avenue Bridge has smaller spans, increasing the risk of debris accumulation and flooding.

Due to its vulnerability, the Stockton Avenue Bridge is identified as a critical at-risk facility in the City's 2013 Local Hazard Mitigation Plan (LHMP). In 2016, a due diligence memorandum was completed to assess the potential impact of debris flow on the bridge during a catastrophic flooding event. The memorandum recommended the installation of debris fins to guide debris through the larger center span of the bridge.

The Department of Water Resources has allocated funding in the Budget Act of 2022 (Stats. 2022, ch. 249, § 207.) to the City to assist in financing the Design, Permitting, and Construction of Debris Diverters on Stockton Avenue Bridge.

The development of a debris mitigation project for the Stockton Avenue Bridge involves conducting a feasibility study and detailed site study, including a hydraulic model, evaluation of alternative debris control measures, consideration of permits, infrastructure requirements, and cost analysis.

Proposals are due on or before 11:00 A.M. on Thursday, January 11, 2024

The Proposal Requirements, including the full Notice Inviting Sealed Proposals, can be obtained on the City's website at www.cityofcapitola.org (Bids and RFPs), at the Public Works office at 420 Capitola Avenue, Capitola CA 95010, or by calling (831) 475-7300.
