RECOMMENDED ACTION
City Council:
1. Extend the current design contract and authorize an increased expenditure authority for bridge engineering design services with Dokken Engineering, in the amount of $200,000, for a revised total contract amount not to exceed $1,058,000.

BACKGROUND
The Vista Canyon Road Bridge project consists of constructing a bridge and associated road improvements, connecting the Vista Canyon Multi-Modal Transit Center to Soledad Canyon Road over the Santa Clara River. The bridge is shown on the attached Location Map. This project supports the Enhancing Economic Vitality theme of the City’s five-year strategic plan, Santa Clarita 2025.
On February 13, 2024, the City Council authorized the City Manager to execute agreements with consultants to finalize plans and specifications for the design of the Vista Canyon Road Bridge project and associated road improvements. This action included a design contract for bridge engineering design services with Dokken Engineering (Dokken) in the amount of $506,000, including contingency.
On June 25, 2024, the City Council awarded the construction contract and associated construction support contracts for the project. At this meeting, the City Council approved an extension of the design contract with Dokken to provide construction support services for the
construction of the project for an additional contract amount of $352,000, including contingency.
Dokken is the structural Engineer of Record for the Vista Canyon Road Bridge project.
In compliance with California Department of Fish and Wildlife regulations, and to protect the fully-protected fish located in the flowing surface water near a set of bridge piers, a revision to the plans was required to avoid the water. The revisions included moving the piers out of the area of flowing water and providing revised plans, structural calculations, and details. In order to accommodate ongoing construction support services, it is recommended that the existing bridge engineering design services contract with Dokken increase by a total of $200,000. The proposal is available in the City Clerk’s Reading File.
The existing project budget will provide for the contract extension that will allow Dokken to continue providing construction support services at regular meetings, reviewing submittals, responding to requests for information, and addressing design issues as the project is constructed.
No additional funding is being requested for this action.
The requirements of the California Environmental Quality Act were satisfied when the City Council approved the Vista Canyon project’s final Environmental Impact Report (EIR) (SCH No. 2007071039) at its regular meeting on April 26, 2011. The recommended actions will not result in any new environmental effect not already considered in the final EIR regarding the project. Consequently, no additional environmental review is required.
ALTERNATIVE ACTION
Other action as determined by the City Council.
