West Trail Living Shoreline Project

Project Location:Pillar Point Harbor
Status:Design, Engineering and Permitting/Bid Docs Issued
Initial Funding:April 4, 2016
Estimated Completion:Winter 2021
Description:Evaluate alternatives to prevent further trail erosion with an emphasis on a Living Shoreline with minimal hard armoring, re-line concrete swale, and stabilize adjacent hillside with planting of native vegetation. 
Justification:The West Trail and adjacent bluffs have sustained substantial erosion. 
Strategic Goal/Operating Impact:1) Comprehensive Long-Range Planning Guides District Actions and Decision-Making
 2) Infrastructure Improvements are Guided by Comprehensive Long-Term Planning. 
 3) Environmental Stewardship

 

May contain: water, outdoors, and nature

On Friday, February 12, 2021, the California Coastal Commission unanimously approved the Coastal Development Permit for the long-awaited Pillar Point Harbor West Trail Living Shoreline Project. The project will restore the West Trail and provide a safe accessible trail to the Mavericks Beach Area, create new beach and dune habitat using an innovative living shoreline approach, and provide lasting protection against coastal erosion and sea level rise. The full Press Release can be viewed by clicking the link at the bottom of this page.

The project is located along the western edge of Pillar Point Harbor (Harbor) in western San Mateo County, California. The Pillar Point West Trail (West Trail or trail) varies in width from 8 to 18 feet and connects a pedestrian pathway from the West Point Avenue access and parking area to the Pillar Point outer harbor and Mavericks Beach. The project area has experienced chronic coastal erosion, resulting in degradation of the existing Pillar Point Harbor West Trail and creating hazardous conditions for trail users. The erosion threatens the structural integrity of the trail for public and emergency vehicle use. In addition, because the trail is the only access point to Mavericks Beach and is a popular trail for visitors, permanent closure of the trail is not favored. The project includes the stabilization of the West Trail and stormwater system improvements. To protect and stabilize the trail, the project will include the construction of a nourished beach with an elevated dune adjacent to, and east of, 300 feet of the trail. Buried beneath the surface of the shoreline and dune would be a cobble berm (otherwise known as a dynamic revetment) and two rock fingers extending perpendicular from the trail. The stormwater improvements would address the aesthetics, function, and maintenance needs of the existing storm drain system as well as provide water quality improvements to the harbor.

With the Development Permit being issued, it is expected the project will be completed in the Fall/Winter of 2021.
