January: Hazardous Waste Collection Event Scheduled for April 19 at Fairgrounds

Boulder County residents can safely dispose of household hazardous waste including paint, solvents, pesticides, batteries, and electronics at a free collection event on Saturday, April 19 at the Boulder County Fairgrounds. No appointment is necessary. Commercial waste is not accepted.

The Pella Crossing open space property encompasses 1,688 acres and features 6 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Affordable housing remains the top priority identified in the 2025 Community Survey. Boulder County’s Worthy Cause program has funded 1,390 affordable housing units since its inception, with 85 additional units in the development pipeline.
