The City of Austin’s Transportation and Development Services Departments are implementing Rough Proportionality as the state-mandated way to verify that transportation improvements required of developers during the application process are appropriate and fair.
Implementation of Rough Proportionality does not require action by Austin City Council or City Staff and will move forward immediately. However, the City is contemplating potential Code amendments to clarify policies related to this process.
Worksheet [.XLS - Updated 9/03/15] DISCLAIMER: This worksheet uses 9th Edition Institute of Transportation Engineers (ITE) trip generation data. As of 2018, the City of Austin references 10th Edition ITE trip generation data.
Applicants may use this worksheet as a rough estimate to determine the limit of transportation improvements they may be required to contribute. However, all official determinations will be performed by the City as a part of the application review process.
For more information on the worksheet or process, please contact the Land Use Review Division: (512) 978-4000, Email, or in person at 505 Barton Springs Road, Austin, 78704.
Development Services Department (DSD) staff is now preparing preliminary and final Rough Proportionality determinations.
Final determinations will be provided to applicants along with transportation review comments.
Preliminary determinations will be provided to applicants upon request.
Implementation of two of the other related changes to the development process,
Elimination of the “pro rata” share for TIA improvements
and Requirements for traffic mitigation without preparation of a TIA or Neighborhood Traffic Analysis (NTA)
will now follow passage of an ordinance clarifying associated City authorities.
This change is in response to stakeholder feedback received during the August public information sessions. Staff will be starting the ordinance process with the Planning Commission Codes and Ordinances Subcommittee on September 15th. This structured process will provide additional opportunities for public education and input, as well as City Council deliberation of these proposed changes.”
