CADD Standards and Specifications

The use of Computer-Aided Design and Drawing standards translates into major operational efficiencies for the District and meaningful cost savings for the Pima County taxpayers. To facilitate project submissions to the District strongly encourages submitters to follow these standards when submitting project plans and drawings to the District.

The District's preferred CADD Standards are available for viewing and downloading from the Arizona Department of Transportation.
