The lawsuit is specifically aimed at protecting coastal resources by protecting the threatened California red-legged frog and the San Francisco garter snake. The Endangered Species Act suit pits conservation groups against the San Francisco Recreation and Park Department for illegal "take" (in this instance, killing) of federally protected species. The crux of the issue for Surfrider is habitat restoration which will lead to better beach management practices and a healthier coast.
According to the Chapter's Vice Chairman, Michael Stewart,
"We feel strongly that an interconnected and protective coastal ecosystem (beach, dune and barrier lagoon) must be recognized as a dynamic, integrated unit; you can't save just one part and expect it to work correctly. This would provide the most benefit to local endangered species, an expansion of desired recreational opportunities, and the best (and least expensive) flood protection for the community at Sharp Park - two, four or even zero legged."
According to a peer-reviewed scientific study by coastal restoration experts, restoration of the natural lagoon and wetlands at Sharp Park will provide the most public benefit, since it (a) is the cheapest public option, particularly compared to the San Francisco Park Department plan or the status quo, (b) will provide the best flood protection for neighbors against sea-level rise and coastal storm events, and (c) is essential for the long-term sustainability of endangered species found on the site.
