The Pitkin County transferable development rights (TDR) system is intended to provide additional tools to implement the Pitkin County Comprehensive Plan and to offer applicants an alternative to the requirement for a GMQS allocation as a prerequisite to development approval. By offering an alternative to the GMQS, the TDR system is intended to increase flexibility by allowing applicants a second, voluntary, way to obtain development approvals in a manner that promotes implementation of Pitkin County Comprehensive Plan goals. The TDR system is designed to protect certain lands in defined Sending Sites from development, to provide the owners of property within those Sending Sites with an additional economically beneficial use of their property, while ensuring that development potential from such properties is instead used in Receiving Sites within the Urban Areas or to permit additional floor area in the Rural and Urban Areas.
