SAN DIEGO (AP) — More storms, rising seas and huge waves are taking their toll on California’s iconic piers that have dotted the Pacific coast since the Gold Rush, posing the biggest threat yet to the beach landmarks that have become a quintessential part of the landscape. At least a half dozen public piers are closed after being damaged repeatedly by storms with multiple atmospheric rivers hitting the state over the past year. Repair costs have climbed into the millions of dollars.
