Man-Made Structures in the California Coastal Zone

Voluntary Local Knowledge Survey 



The goals of this project are to:

               - 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.  To learn more about projects that they fund, events and activities you may visit their website at:

Sunbathing     Sand Sports     Boating      Other :    

Is there a certain time of year that you visit the ocean more frequently?
In the summer     In the winter     No, I am there year-round  



Occasionally additional sand is put on the beach by humans through a management practice known as “beach nourishment” (intended to widen beaches or dispose of excess sand from harbor dredging).
Which statement most closely matches your opinion of this practice?

        I disapprove of it completely.
        I believe that it should be considered in certain areas.    
        I think it is a good solution for areas impacted by erosion.    
        I have no opinion of it.

Have you ever observed the human addition of sand to beaches in your area?
No     Yes -- if yes, please answer the questions in the box below 

Where?

From your observations, what impacts do you think the addition of sand had on recreation?
 None     or describe:    

From your observations, what impacts do you think the addition of sand had on local plants and wildlife?
 None     or describe:    

How long did you notice the presence of the additional sand? less than 1 month     1 month to 1 year     more than 1 year     I don't know  




Many structures like the one shown in the photo above have been in place for 30 years or more. Think of a similar structure on a beach that you frequently visit. Which statement is closest to your own opinion?
       I like it, I think it serves a useful purpose and improves the beach.    
       I consider the structure to be a part of the beach and I don’t really think about it much.  
       I think of the structure as an unnecessary annoyance.    
       I don’t know or I can’t think of a structure near me.    

Which statement is closest to your opinion on the visual impact of these structures?
       They are eyesores on our beautiful beaches.    
       I don’t mind them but I would change their appearance if given the option.  
       I think the aesthetic impact is negligible.    
       I think they improve the appearance of the beach.    

Do you consider these structures to be dangerous?
       No    
       Yes    

Which of the following statements do you most closely agree with?
       All of these structures have a negative impact on areas located down the coast.    
       Some these structures have a negative impact on areas located down the coast.    
       None of these structures have a negative impact on areas located down the coast.    
       I don’t know.    

In your opinion, do these structures commonly trap additional litter and pollutants?
       No  
       Yes    

Have you observed any plants or animals on or around these types of structures that are not present elsewhere in the immediate coastal area?
No     Yes -- if yes, please answer the questions in the box below
