Document Description: The California Department of Transportation (Caltrans) proposes to repair a culvert on State Route 1 at Post Mile (PM) 4.47 in the town of Anchor Bay in Mendocino County. The proposed project is to replace the culvert downdrain. No work will be done in the existing crossdrain, except where the new cable-anchor system will be attached to the last joint of the existing culvert; Therefore no concrete pile anchors will be required. Removal of the existing downdrain will involve debris and/or vegetation clearing and grading. The existing downdrain will then be replaced by a new rock-lined ditch and black plastic downdrain. The rock-lined ditch will contain two pools that serve as frog habitat and willows will be planted between the rocks. There will be no excess dirt because the slope of the new downdrain will be determined by re-grading the existing embankment.
