On July 14, 2021, Denver Water filed a lawsuit in U.S. District Court against Boulder County, asserting the county is overreaching its authority and jeopardizing a federally ordered reservoir expansion critical to a safe and secure water supply for one quarter of the state’s population while risking long-planned benefits for the West Slope environment.

What is a 1041 Permit?

Colorado House Bill 1041, also known as the Areas and Activities of State Interest Act, was enacted in 1974 and allows local governments to regulate, through established criteria, a variety of development activities with guidance from the state.

Projects of this scale do not jump right into construction, rather they take many years of planning, study and review.

1041 Permit Documents

Boulder County’s 1041 regulations are listed in Article 8 – Location & Extent Areas & Activities of State Interest (1041)
