Wildfire Mitigation Regulations - Section 16
Section 16 - Wildfire Mitigation Regulations
On January 28, 2020, the Ouray County Board of County Commissioners (BOCC) adopted significant revisions to the County’s Wildfire Mitigation Regulations, which become effective May 1, 2020. (Click here for a copy of the new regulations.) The original wildfire Code section was adopted in 1997. The updated regulations were developed over two years, and the process included cooperation between Ouray County (Planning Commission, and Use Staff, BOCC), local fire departments / fire districts, the Colorado State Forest Service, and the West Region Wildfire Council (WRWC).
The revised regulations were developed using current wildfire science and takes into consideration recent scientific studies on wildfire and the "Wildland Urban Interface" or "WUI." Wildland Urban Interface is commonly defined as "a zone of transition between wildland or unoccupied land and human development."
