Man-Made Structures in the California Coastal Zone
- Encourage communication between scientists, coastal planners, residents and beach users.
- Document local knowledge of the coastline.
- Determine how man-made coastal structures may impact beaches.
As you know, sandy beaches are one of our state’s greatest natural assets. One way in which we have altered sandy beaches is through the construction of artificial structures along the shoreline. There are currently more than 200 man-made structures on the California coast that extend from the beach into the ocean. These structures include groins (used to hold sand in place), jetties (to keep harbor entrances and river mouths open), breakwaters (to reduce wave energy), piers, wharves and fences. People, the beach, and the ocean all interact with man-made coastal structures in different ways that are not well understood.
This survey was inspired by conversations with beach users in the Ventura area. These conversations highlighted the lack of connection between scientific observations and local knowledge. Many Californians regularly observe/interact with portions of the coast and develop an awareness and understanding of both typical and unusual local conditions. This direct local knowledge is rarely recorded or explored. Thousands of dollars of expensive equipment and scientific research cannot duplicate the historic observations that some regular beach users possess.
This survey asks questions that will try to document your local knowledge of the effects that man-made coastal structures in your area have on recreation, ecology, sandy beaches and ocean waves.
The results of this survey will be used to evaluate the performance of existing structures, document public opinion of their effectiveness, appearance and impact and to increase our understanding of how these structures influence the coast. This survey has no direct influence on management decisions in your immediate area but the findings will be made available to both local and state planners.
This academic survey is being conducted by the Coastal Lab at the University of California, Santa Cruz. Funding for this project was generously provided by the Friends of Long Marine Lab in Santa Cruz, CA.
