    Transportation improvement plans include paving, grading, and drainage plans for subdivisions and offsite. DOT improvement plans are associated with Subdivisions within Unincorporated Pima County and go through a Pima County review and acceptance process. In addition, DOT improvement plans are tied in with Roads Accepted for Maintenance (RAM’s) which are approved by the Board of Supervisors.

    DOT improvement plans are added into Engineering Information Management. Note that more than one improvement plan may exist for a particular area. You can view Historical DOT Improvement Plans two ways.
