Program Highlights:

  • Vision Sonora–Funded by a Caltrans grant, Vision Sonora is a community revitalization plan that addresses traffic congestion, transit facilities, multimodal connectivity, economic development, and beautification along the Highway 49 and Washington Street corridors.  Improvements to pedestrian and bicycle pathways and facilities, public spaces, parks, and traffic circulation enhance the quality of life for residents and boost Sonora’s tourism.  The Vision Sonora Plan won an Outstanding Planning Award by the American Planning Association.
  • Trail Me About It–Tuolumne County is a popular destination for hikers or bicyclists with its many scenic trails.  These trails facilitate recreation, volunteer efforts, tourism, and physical activity.  The Trail Me About It Fund provides micro-grants to community groups, non-profits, and clubs for trail improvements.  The fund’s main goal is to encourage residents to bike and walk more frequently and connect with their surroundings and community.  Trail improvement projects include trail planning, maintenance, amenities, signage, and maps.
