ENVIRONMENTAL IMPACT
ENVIRONMENTAL DETERMINATION: Consideration and possible adoption of a Categorical Exemption Class 1: It has been determined that this type of project does not have a significand effect on the environment and is exempt from the California Environmental Quality Act. [See Class 1 (Existing Facilities”) which may be found in the guidelines for the implementation of the California Environmental Quality Act at 14 CCR 15301; see also Napa County’s Local Procedures for Implementing the California Environmental Quality Act, Appendix B.]
BACKGROUND AND DISCUSSION
Partrick Road Bridge was constructed in the early 1900’s and the 17-foot-wide bridge served well until it was damaged in the 2014 South Napa Earthquake. To allow for the safe passage of vehicles after the earthquake, rock was placed to stabilize the wing walls and the guardrails were cutoff to make room for a temporary steel truss bridge that was later placed over the top. This temporary bridge does not set on a permanent foundation and needs to be replaced. The permanent repair consists of concrete casted in drilled holes that are capped with a reinforced concrete grade beam/abutment that a new steel truss bridge will set on. The new bridge is 20 feet longer than the temporary bridge which will promote stability and facilitate repairs with minimal road closures, although some closures will be needed. The new bridge has a width of 18 feet which is 1 foot wider than the bridge damaged in the earthquake and approximately the same width as the existing roadway in the area. Although FEMA could have considered the extra width a betterment they did not because the prefabricated bridge is only available in certain standard sizes. County standards for newly constructed bridges is to have 24 feet between the guardrails on the deck but increasing this dimension by 7 feet at the existing site would certainly be considered a betterment by FEMA and make permitting and construction significantly more difficult and costly. FEMA and CalOES have obligated 96% of the $1,072,764.12 requested for the project. FEMA will not obligate any funding toward contingency prior to construction however and if contingency is needed to deliver the project, the County will later be able to request funding from FEMA and CalOES for these costs as part of the project closure process. After completion of this project, the temporary bridge which was purchased by the County will be retained for use in future emergencies. FEMA has reimbursed the County for use of the temporary bridge and is paying to have it moved to storage.
The Board approved funding to start design for the permanent repair on July 12, 2022, the County later submitted a repair plan to FEMA and received notice from CalOES that it was approved on February 17, 2023. After bid results, staff will return to the Board of Supervisors to request construction award and a budget transfer from the Accumulated Capital Outlay Fund to fund the entirety of the project. Staff recommends approval of the Plans and Specifications and authorization to advertise the project.
