Approval by the Director & State Design Engineer, Development Division, or designee, is required (see Chapter 530). access hearing plan A limited access plan prepared for presentation at an access hearing. access management The programmatic control of the location, spacing, design, and operation of driveways, median openings, interchanges, and street connections to a roadway.

See Chapter 550. access report plan A limited access plan prepared for presentation to local governmental officials at preliminary meetings before preparation of the access hearing plan. access rights Property rights that allow an abutting property owner to enter and leave the public roadway system. accessible Usable by persons with disabilities (ADA compliant).
