The Lower Blue Master Plan serves as a foundation to guide development in the Lower Blue River Basin in Summit County, which extends north from Dillon Reservoir to the county border.

Used in combination with the Countywide Comprehensive Plan, the Lower Blue Master Plan contains guidance on appropriate land use throughout the basin, including the protection of the area’s rural character north of Silverthorne, and recognition of existing development patterns.
