Surfrider Foundation just launched its State of the Beach Report for 2005. This year’s report focuses on beach fill, commonly referred to as beach nourishment. Why is this a hot topic? Well, as discussed in the intro to the report, our beaches are disappearing in many areas because we’ve blocked off the historical sources of sand supply by damming rivers and building jetties, groins and seawalls. We’ve also made the problem more acute by building too close to the shore.
The best long-term solution is moving back from the shore, but that’s obviously easier said than done. We don’t want more seawalls, so beach fill is often all that’s left.
As discussed further in the Indicators section of the report, we believe “beach nourishment” is a somewhat misleading term, because although we’re “feeding” the beach, it’s not necessarily getting healthier.
Beach fill is neither inherently good nor bad, but we think it’s important that states and municipalities go into these projects armed with the facts. What are both the initial construction costs and the ongoing costs for “re-fill” of the beach every “X” years? Who will pay for this? Is the imported sand compatible with the natural sand? Will there be ecological impacts at either the dredge site or at the filled beach? Is there adequate public noticing?
We illustrate some of the issues that arise with beach fill projects by presenting case studies of beach fill projects in Bogue Banks, North Carolina; Puerto Rico; and San Diego, California. At some sites the project was well planned and executed; in other cases there were big problems. See which is which.
Also, read the Perspectives titled “Fill Effects”, “Beach Management”, “Beach Barriers”, “Florida Beaches” and “Sand Dollars” for views on these issues from researchers, managers, beach/ocean users and others.
More details regarding beach fill policies and an inventory of projects in each state are available in each of the state reports. For instance, check out this one for Florida.
