The Menlo Park City Council tonight is to consider flying in formation with other Peninsula cities that have followed San Mateo County's lead by adopting carbon-copy laws that ban use of plastic carryout bags.

The county is trying to marshal as many cities as possible to pass the laws by April 22, which is, not coincidentally, Earth Day.

San Bruno, Belmont, Millbrae, Pacifica, Portola Valley, Daly City, Colma, Foster City and South San Francisco have already adopted or are in the process of approving plastic bag bans modeled after one the Board of Supervisors approved in October for unincorporated areas.

Under the ordinance, stores are prohibited from offering customers plastic bags for carry-out purchases and must charge a dime per paper bag. Beginning on Jan. 1, 2015, the price of paper bags will go up to 25 cents.

Other San Mateo County cities scheduled to hold public hearings and consider adopting plastic bag bans this month include Half Moon Bay, San Carlos, San Mateo and Woodside, according to Robyn Thaw, a county spokeswoman.

And next month, the law will come before the city councils of Redwood City, East Palo Alto and Burlingame, she said.

A handful of Santa Clara County cities also are on track to implement the law -- Mountain View has already approved it and Cupertino, Los Altos and Los Gatos will consider adoption this month.

Brisbane, Campbell and Milpitas also have expressed interest in the ban, but haven't yet scheduled hearings; Atherton and Hillsborough are not participating because neither town has applicable retail businesses, Thaw said.

Supporters of such laws say the thin plastic bags pollute waterways and landfills, clog storm drain systems and harm wildlife.

An industry group of plastic bag manufacturers called the American Progressive Bag Alliance has publicly opposed the bans, dismissing them as misguided efforts that unnecessarily pass on costs and inconvenience to consumers.

Menlo Park's council will meet at 7 p.m. inside council chambers at 701 Laurel St.
