This is an addendum to the previously adopted CEQA/NEPA document that will allow a new project construction work window from April 16 through October 30 to a new work window of March 15 through December 15. The project is proposing a habitat restoration project in order to increase the spawning success and to enhance juvenile rearing of the Central Valley fall and spring run Chinook Salmon.
There would be no change to the work activities as described in the Project CEQA/NEPA document and work window extension would not change whether or not there would be overlap between construction and critical periods for sensitive species (see Table 15 from Hallwood CEQA/NEPA document, included below for reference). All mitigation measures currently in place to protect special status species and water quality would continue to be implemented, including pre-construction surveys, buffers, construction monitoring for sensitive species and water quality impacts, and fish impact avoidance measures. Air quality impacts would be lower than in the original CEQA analysis because the same amount of work would occur over a longer time period, and more fuel efficient equipment will be utilized. Therefore, the extension would not change the significance level of any environmental impacts.
