City Waste Initiatives

We are taking steps to reduce, reuse, and recycle the waste that we create. To that end, Walnut Creek has voted to eliminate litter from plastic bags and polystyrene (Styrofoam) with the following ordinances:

Polystyrene Ordinance

Walnut Creek's Polystyrene Ordinance was approved on May 20, 2014. The new law takes aim at a pervasive and persistent type of litter by restricting the distribution of food containers made from polystyrene foam, commonly referred to as Styrofoam. The ordinance took effect on December 18, 2014, for all food vendors in Walnut Creek (which includes restaurants, cafes, delicatessens, and food trucks). Learn more about the ordinance.

Plastic Bag Ordinance

Plastic bag

As of September 18, 2014, single-use plastic checkout bags have been eliminated from all retailers. Paper bags made of post-consumer recycled materials may be sold at a minimum of 10 cents per bag. To avoid the bag fee, shoppers are encouraged to bring their own reusable bags.Learn more about the Plastic Bag Ordinance.
