Transportation Conformity
Transportation Conformity Determination
Alamo Area MPO reevaluated the required Air Quality Analysis used to develop the 2024 Transportation Conformity Determination (TCD) and the draft document is available for public comment. Public Comment on the draft TCD and the related FY 2025-2028 Transportation Improvement Program will continue until Transportation Policy Board adoption. The initial public comment period ran from April 29, 2024 to May 31, 2024. Since then, projects have been revised and reanalysis is complete. All public comments received will be addressed and documented in the final version of the TCD’s Appendix G. This Determination is being developed to meet the requirements of the 2015 8-hour Ozone NAAQS based on Bexar County’s current nonattainment status of Serious. The AAMPO Transportation Policy Board will consider the 2024 Transportation Conformity Document and make a local determination of conformity as soon as possible. To stay up to date, or get more information, please track the Technical Advisory Committee and Transportation Policy Board meetings or contact Sonia Jimenez at jimenez@alamoareampo.org or by phone at 210-230-6904.
