Beachgoers will need to wear face coverings while at Hermosa and Manhattan Beach piers. Both cities have hired a private security firm to enforce the rule.
Fines can range from $100 to a first-time offense to $350 for repeat offenders.

Some beachgoers in Hermosa Beach on Thursday said wearing a face covering is the best option for yourself and everyone.
"I think it's a great idea so that we can all get healthy all at once, because I want to open the whole state. I'm ready to get back into restaurants. I think it's a great idea," said Krysta Piper.
