Castle Valley at a glance
Grand County · Utah
Castle Valley is a small rural town in Grand County, set in a valley about 8 miles long and 3 miles wide below the La Sal Mountains. The valley formed when salt layers laid down more than 300 million years ago dissolved and the rock above them collapsed. Ranching gave way to a subdivision, Castle Valley River Ranchos, whose plat was approved in 1973, and the town incorporated in 1985. The town is zoned rural residential and agricultural, with no commercial or industrial zoning, and it was certified as a Dark Sky Community by DarkSky International in December 2023.
The town website posts Town Council and Planning Land Use Commission agendas, minutes, audio and video, grouped by year. Building permits come from Grand County, but the town handles zoning approval first, and unusual projects go to the Planning Land Use Commission. A separate water page explains that a water-use agreement lets a lot owner use a set amount of the town's water and does not create a separate water right. To follow a decision, match the posted agenda to the approved minutes for the same meeting.
