Uses Within the TUC

A TUC use may occur on, above or below the corridor land surface. Above-ground utilities (powerlines) and underground utilities (pipelines) both have designated alignments that provide for access maintenance, landscaping, etc. Due to this multi-level aspect of uses, there may be two or more uses at a specific location within the corridor. There are three categories of uses recognized within the TUC: Primary, Secondary and Original.

Primary Uses are linear transportation and utility facilities that the TUCs are planned to accommodate. These uses include Ring Roads and associated interchanges and stormwater management facilities, petroleum pipelines, power transmission lines, telecommunications lines, and municipal regional water, sanitary and storm sewer lines. A TUC primary use, such as a roadway, may be planned but not yet built.

Secondary Uses usually occur next to roadways, above underground pipelines, or below powerlines. These uses include agriculture, utilities, parking, outdoor storage, recreation and commercial activities. Secondary Uses include subdivision-related contouring that encroaches onto a TUC, noise attenuation barriers, pathways and supplemental landscaping plants. These Secondary Uses are temporary, and care has been taken to ensure that these uses can easily be altered, or displaced, to accommodate Primary Uses.

Original Uses
While most of the TUC lands have been designated for various Primary Uses, the actual land use within portions of the corridors remains unchanged since the beginning of the program. The TUCs will take many more years to become fully developed. These Original Uses include agricultural, residential (mainly original farmsteads), sand and gravel mining, etc. Presently, much of the TUC land in which Original Uses have been retained are owned by INFRAS and leased out. Leasing assists with the maintenance of this land and generates revenue. As Primary and Secondary Uses are gradually developed, these Original Uses will be modified or displaced.
