An Administrative Decision (AD) is a written decision given by the Office of the State Traffic Administration (OSTA) at the request of the property owner or his/her authorized representative regarding the need for formal OSTA action (i.e., certification) concerning major traffic generators/expansions/land use changes.  If traffic impact analysis demonstrates that the added traffic associated with a major traffic generator/expansion/land use change does not trigger the need for mitigation or traffic safety measures on the state highway system, a request for an AD regarding the development proposal must be submitted to the OSTA.  The AD request form/checklist details the required information that must be submitted to the OSTA.  An AD will be rendered precluding formal OSTA certification once the submitted information is fully vetted by the Department confirming no substantial impact to the state highway system.

Trip Generation Guidelines - October 2023

 

As of November 16, 2015, the following Engineering Bulletin must be considered in the hydraulic information/analysis submitted regarding major traffic generators.  Engineering Bulletin EB-2015-2 (Precipitation Frequency Estimates) has been issued and posted on the Engineering and Construction Information Resources web page.

 

Please be advised that the Department separately regulates any work in the State highway right of way under the encroachment permit review process (i.e., utility connections, driveway curb cuts, etc.)   The rendering of an AD does not preclude the need for an encroachment permit.  CLICK TO VIEW MORE DETAILED INFORMATION REGARDING THE ENCROACHMENT PERMIT REVIEW PROCESS.
