Environmental Impact Statement
What is an Environmental Impact Statement?
An Environmental Impact Statement (EIS) is a full-disclosure, public document that includes an analysis of a full range of alternatives (including the “No-Build,” or do nothing alternative) and an assessment of potential environmental impacts through the evaluation process. A broad range of environmental issues have been studied and the findings reported, such as: water quality, air quality, cultural resources, biological resources, socioeconomic conditions, community cohesion, noise and more. The EIS includes a summary of the public involvement efforts and the context-sensitive solutions process. This document is required by the National Environmental Policy Act (NEPA) of 1969.
The following includes the downloads for the Draft Environmental Impact Statement and the Final Environmental Impact Statement and Record of Decision.
Draft Environmental Impact Statement
On May 4, 2018, TxDOT and the Mobility Authority, as co-lead agencies, published the Draft Environmental Impact Statement (DEIS) for public and agency review. Public comment received by Friday, June 29, 2018 was included in the official record of the May 2018 public hearing.
