SAN CARLOS, Calif.—San Carlos is set to become the latest California city to ban plastic carryout bags.

The San Carlos City Council voted 4-1 Tuesday to adopt an ordinance that bans stores from offering plastic bags starting July 1. Customers will have to pay 10 cents for each paper bag, a charge that increases to 25 cents in 2015.

Officials say the ordinance will reduce the number of plastic bags that pollute waterways and clog storm drains.

The San Mateo Daily News (http://bit.ly/Va1OGs) reports that 10 San Mateo County cities have already banned plastic bags and another eight cities are considering such bans.

Mayor Matt Grocott voted against it, citing potential health risks to people who don't wash their reusable bags.

The Redwood City council will consider a plastic-bag ban in March.
