Action Alert: Tell Caltrans to study impacts before advancing the Four Bridges Project


Avenue of the Giants

Avenue of the Giants


The California Department of Transportation (Caltrans) is proposing to upgrade four existing  bridges along the Avenue of the Giants, a world-famous scenic drive along old Highway 101, through the ancient redwood groves of Redwood State Park.

Take Action: Tell Caltrans that it needs to adequately study impacts, and adequately inform the public, before they move forward with the project.

Caltrans released an Initial Study with Proposed Mitigated Negative Declaration for the “Avenue of the Giants – Four Bridges Project” over the holidays, comments are due on Monday, February 2.  (A “Mitigated Negative Declaration” is a CEQA document that essentially says that environmental impacts will be mitigated below significant levels, and therefore that further study of the project impacts is unnecessary.) As proposed, this project would involve upgrades to bridge and guard railings and repaving of the existing roadway on each side of four bridges on Avenue of the Giants/Route 254, and all of this work would occur within and around ancient redwoods and important salmon habitat. Yet, despite the precious resources potentially threatened by this project, Caltrans is pushing the project through without adequately analyzing or disclosing to the public the impacts of the project.

 Tell Caltrans: * Impacts to redwoods need to be fully analyzed, and all conclusions need to be fully explained to the public, before work begins in and around their roots. * Adequate, and fully explained, measures to avoid spills or other stream disturbances need to be developed before Caltrans begins working over streams with important fish habitat. * Caltrans needs to recirculate the Initial Study with Proposed Mitigated Negative Declaration with all underlying studies and documents in order to be transparent with the public about the project and its potential impacts to public resources, and in order to comply with CEQA which requires that the public be provided this information for comment.

Impacts to Trees Caltrans maintains that the project area contains 46 coastal redwood trees. While the Initial Study and Proposed Mitigated Negative Declaration notes that “[i]t is difficult to develop a mitigation strategy that adequately offsets a project’s impacts to old growth redwood trees, due to their size and age,” it nevertheless concludes that the study will have “less than significant” impacts on these trees. The impacts on each tree in the area were rated on a 0-6 scale corresponding with the magnitude of impacts of the projects on the tree: eleven trees were rated “0” (no effect); fourteen were rated “1” (effect of root zone disturbance is extremely minor with no decline in foliage density or tree health); and twenty-two were rated “2” (effect of root zone disturbance is very sli
