Only 20 foot waves, no biggy.
"The Coastal Sediment Management Workgroup is drafting a Coastal Regional Sediment Management Plan for the San Francisco Littoral Cell, which extends from the Golden Gate to south Pacifica. A draft of the plan is expected in January.

Diagrams of sea level rise predictions show different problems, including no beach in Pacifica in the winter. Sea level rise predictions steadily work away at the coastline, taking away, for example, the Pacifica Pier and Beach Boulevard in Sharp Park and much of the existing beach at Linda Mar. 

The study predicts what will happen in 50 years if nothing is done and tells residents what action plans are available.  For Pacifica, beach nourishment or managed retreat is recommended in different areas. The plan presents opportunities for funding to fix these problems if recommendations are addressed through economies of scale. Funding is possible through the Corps of Engineers or California State Parks’ Division of Waterways."  Read article.

Wouldn't it be ironic for one of those loose containers to take out our pier. An EMPTY container takes out the only place that is really unique to Pacifica.
Find the metaphor.
