Sherwin Area Trails Special Study (SATSS)

Project Description: In the fall of 2008, and in partnership with the U.S. Forest Service (USFS) and MLTPA, the Town of Mammoth Lakes (TOML) launched an important new project: the Sherwin Area Trails Special Study, or SATSS. SATSS identifies options for trails within its defined study area, options for recreational uses and/or activities, and opportunities for public access between the study area and the Town's existing trail system. This study area is defined as the general area south of the Urban Growth Boundary (UGB) between the Hayden Cabin site and Sherwin Creek Road on the east and Old Mammoth Road on the west, up to Lake Mary Road. 

Alta Planning + Design, the lead consultant on the Trail System Master Plan (TSMP) update, conducted fieldwork and analysis. Options and opportunities are considered for winter and summer uses, both motorized and non-motorized. SATSS will be combined with the efforts of the Sherwins Working Group (SWG), and the ultimate deliverables of these efforts will be included as an attachment to the TSMP. For more information on SATSS, please contact TOML Principal Planner Steve Speidel at
