Present Land Use
The Westport Union Landing Beach State Park lies to the south of the project area. To the north is Juan Creek followed by Hardy Creek and timberland. To the east is considered remote residential. The project's immediate environment is composed of an area approximately 80 to 240-feet above sea level overlooking the Pacific Ocean in Mendocino County. The area has expansive views westward of the Pacific Ocean, of coastal bluffs to the north and south, and of the Coast Range, which rises above the shoreline to the east.
Document Description
The California Deparment of Transportation (Caltrans) is proposing a storm damage permanent restoration project on Highway 1 from postmile (PM) 82.0 to 82.3, in Mendocino County north of Westport. The project is necessary due to substantial bluff erosion caused by the 2005 and 2006 winter storms. The project work includes constructing two retaining walls at PM 82.09 and 82.21. In addition, work includes replacing metal beam guardrail, improving drainage, paving, and relocating telephone utilities. The project will have appropriate sediment control devices, aesthetic treatments, revegetate distributed areas, place erosion and water quality control protection measures, and use both state and federal funding.
