In 1982, the Tahoe Regional Planning Agency adopted nine environmental thresholds that set environmental standards for the Lake Tahoe basin. The majority of the 168 Threshold standards are based on science that is now over 30 years old.
In 2015, the Council performed a review assessment of these thresholds and the associated standard structure. Following this initial review, the Council has lead multiple related projects to help TRPA advance its Threshold Update Initiative.
Threshold standards are in nine categories: Air quality, water quality, soil conservation, vegetation, fisheries, wildlife, scenic resources, noise, and recreation.
All Council work aims to collaboratively create relevant and scientifically rigorous Threshold standards that are cost-efficient, feasible and inform a comprehensive monitoring and evaluation plan.
