Frank and Fran Robinson, an unassuming couple who moved to Newport Beach in 1962, learned about the already-approved plans to turn the Upper Newport Bay—also known as the Back Back—into a massive development of extended shorelines, homes, a marina, businesses, and a waterskiing and rowing venue. Even though the dredging had already begun, the Robinsons decided to take on the Irvine Company, one of the largest land developers in the country, to preserve for the public one of California largest estuaries. After a decade-long battle, David slayed Goliath and saved the Back Bay.
