The Los Angeles City Council voted 12-0 Wednesday to draft an ordinance requiring new supermarkets to create a retrieval system for their shopping carts.

The proposal is designed to reduce in the number of carts that are abandoned on curbs, sidewalks and in alleys across the city.

Councilman Tony Cardenas, who proposed the law, said the carts create visual blight and pose a danger when children start playing in them. The proposal would apply to new stores and existing supermarkets that undergo a major renovation, Cardenas said.
