  1. Make Your Voice Heard!

Your voice is critically important and highly effective at protecting Open Space lands from dangerous industrial uses and development on protected lands.

As Boulder County’s application to itself to approve its own industrial-scale waste facility on your Open Space lands advances, it is critical you make your voice heard and opinion known.

First, sign-up below to receive important updates from Protect Rainbow Open Space. When your voice and support is needed, we will let you know.

Next, take a moment to send an email to your Boulder County Commissioners (commissioners@bouldercounty.org) and to the County Planning Commission (planner@bouldercounty.org) and let them know what you think about their plan to build a “composting facility” on protected Open Space and irreplaceable Agricultural Lands of Significance.
