Environmental Assessment

An Environmental Assessment (EA) for 183A Phase III was developed to study the potential impacts of the Project on the human and natural environment, in accordance with the National Environmental Policy Act (NEPA).

A Finding of No Significant Impact (FONSI) was issued in August 2019 by the Texas Department of Transportation Environmental Affairs Division, clearing the way for the project to proceed.

An EA is a public document that provides sufficient evidence and analysis for determining whether TxDOT should issue a FONSI or prepare an Environmental Impact Statement (EIS).

The Final EA and supporting documentation are available for public review below.
