Del Mar City Council has passed a plastic bag ordinance that will ban plastic bags.
Shoppers will now have to bring their own reusable bags or pay 10 cents for a paper bag.
Encinitas and Solana Beach already have similar bans.

There will be a 12-month grace period for restaurants, food vendors and farmers' markets.
