Summary

Lancaster's code defines what counts as green waste for curbside collection: tree trimmings, grass cuttings, leaves, branches and dead plants, so long as no single piece exceeds six inches in diameter or forty-eight inches in length. Material within that size limit goes out in the green organic waste container under Chapter 13.18; anything larger has to be handled as bulky yard debris instead.

"Green Waste" means tree trimmings, wood stumps, small pieces of wood, grass cuttings, dead plants, leaves, branches, flowers, plant stocks, and dead trees (not more than six (6) inches in diameter or forty-eight (48) inches in length) and similar materials.

Full Breakdown

020 of the Municipal Code defines "Green Waste" for purposes of Lancaster's organic waste program as tree trimmings, wood stumps, small pieces of wood, grass cuttings, dead plants, leaves, branches, flowers, plant stocks, and dead trees, but caps the size of that material at not more than six inches in diameter or forty-eight inches in length. 030(C) requires single-family generators to place source separated green container organic waste, which includes yard material meeting the Green Waste definition, into the green container for weekly pickup alongside food scraps and other compostable material, rather than the gray trash container or blue recycling container.

030(A), by composting on site or using a community composting site rather than subscribing to the green container service for that portion of their waste stream. 080, which excludes anything over four feet long or sixty pounds from weekly service and requires the owner to haul it to a city-designated disposal site at least once a month. The two thresholds work together: routine trimming and mowing debris moves through the weekly green container, while oversized branches and yard debris from tree removal or major pruning fall outside the green container program entirely and require the separate monthly bulky-item process.

Violations & Fines

Placing oversized branches, stumps or yard debris exceeding six inches in diameter or forty-eight inches in length into the green container is a Prohibited Container Contaminant under Chapter 13.18 and can result in the container being flagged for contamination and, after a route review, an enforcement notice. That material has to go through the separate monthly bulky-item disposal process under Section 13.16.080 instead.

Frequently Asked Questions

What size tree branches can go in Lancaster's green waste bin?
Only branches and trimmings that are no more than six inches in diameter and no more than forty-eight inches long qualify as Green Waste under Section 13.18.020 and can go in the green container. Anything larger has to be handled as a bulky item under Section 13.16.080 and hauled to a city-designated disposal site instead.
What counts as green waste in Lancaster?
Section 13.18.020 defines Green Waste as tree trimmings, wood stumps, small pieces of wood, grass cuttings, dead plants, leaves, branches, flowers and plant stocks, and dead trees, provided no piece exceeds six inches in diameter or forty-eight inches in length. Material meeting that definition is source separated organic waste for the city's green container program.
Can I compost my own yard waste instead of putting it in the green container?
Yes. Section 13.18.030(A) allows generators to manage organic waste, including qualifying green waste, by preventing or reducing generation, composting it on site, or using a community composting site, as an alternative to placing it in the green container for city collection.
