The Ninth Circuit Court of Appeals is upholding the Tahoe Regional Planning Agency’s landmark 2012 Regional Plan , to restore Lake Tahoe’s environment and revitalize its communities.  Joanne S. Marchetta, executive director of TRPA says the plan is based on sound science, planning, and analysis and represents the best path forward for TRPA and its many partners to restore Lake Tahoe’s treasured environment and revitalize our communities.  Sierra Club and Friends of the West Shore filed a lawsuit against the Regional Plan shortly after the TRPA Governing Board adopted it in December 2012. U.S. District Court Judge John Mendez found the lawsuit to have no merit and dismissed it entirely in April 2014, prompting the two groups to appeal his ruling to the federal Ninth Circuit Court of Appeals.
