Open Space and Trails Advisory Board

When Arapahoe County voters approved a 0.25 percent sales tax in November 2003 for the preservation of open space, parks, and trails, they also created the Open Space and Trails Advisory Board (OSTAB).

Made up of seven members from across the county, the board is responsible for:
  • Reviewing proposed projects
  • Making recommendations regarding the distribution of revenue
  • Performing other duties as permitted under the resolution
