This Land Use Code is intended, in part, to implement the Pitkin County Comprehensive Plan. The preservation of the rural and agricultural character of Pitkin County is a primary goal of the Pitkin County Master Plans. Consistent with this goal, an urban growth boundary has been defined around each of the City of Aspen and the Town of Basalt. Additional urban growth boundaries, or modifications of the existing boundaries, may be adopted in the future. In order to implement the goal of protecting rural and agricultural character, this Land Use Code groups the available zone districts in Pitkin County into those generally intended for use within urban growth boundaries (and the existing townsite of Redstone) and those generally intended for use outside those boundaries. For purposes of this distinction, the unincorporated Townsite of Redstone is treated as a non-Rural Area, and is grouped with areas inside of urban growth boundaries. A map of the adopted urban growth boundaries is shown in Figure 3-1.
Lands located within adopted urban growth boundaries or the townsite of Redstone are sometimes referred to in this Land Use Code as “urban” lands or “urban” areas. Lands located outside of adopted urban growth boundaries and the townsite of Redstone are sometimes referred to in this Land Use Code as “rural” lands or “rural” areas. In those cases where zone districts intended for use inside the urban growth boundaries (or Redstone) have already been mapped outside those boundaries, such zone districts will remain in effect. After the 5th of July, 2006 of this Land Use Code, applications to rezone land outside the urban growth boundaries (and Redstone) to a zone district intended for use inside the urban growth boundaries will not be approved. In general, any proposed development that is required to be reviewed by the State of Colorado site application process because of estimated water requirements or wastewater generation (based on State of Colorado standards) should not be located in a Rural Area of the County.

In order to implement the Pitkin County Comprehensive Plan, the development potential from certain lands is sometimes permitted to be transferred to lands elsewhere in the County, under certain conditions. In some circumstances, transferred development rights (TDRs) may be used to create a development right on a parcel that does not have one, and in other cases transferred development rights may be used to expand the size of a house above the base floor area permitted, but within the limits on maximum house size established in Table 5-1. The descriptions of each zone district in this Chapter 3 include information on (a) whether TDRs may be transferred from the district, (b) whether TDRs may be transferred into the district, or within the district, and (c) the purposes for which purchased TDRs may be used in various zone districts. The procedures for transferring development rights are set forth in Chapter 2.
