Notice of Finding of No Significant Impact (FONSI) and Final Environmental Assessment for Public Review – FM 664 from US 287 to Westmoreland Road


This notice advises the public that TxDOT has issued a finding of no significant impact (FONSI) for the FM 664 widening Project, and that the FONSI is available for public review.  


The proposed project consists of the reconstruction, realigning, and widening of FM 664 from US 287 in Waxahachie to Westmoreland Road in Ovilla, TX. Improvements would include the expansion of the current 2-lane rural roadway to a 4-lane urban roadway (ultimate 6-lanes) with a raised median to provide additional capacity and improve safety. Improvements would consist of 12-foot wide travel lanes, 14-foot wide outside shared-use lanes, and 6-foot sidewalks with Americans with Disabilities Act (ADA) curb ramps in both directions. Other improvements would include eliminating 90-degree turns along FM 664 between FM 1387 and Marshall Road.

The proposed project is anticipated to require 87.18 acres of additional right-of-way (ROW) and 0.61 acre of proposed easement.

Memorandum of Understanding:

The environmental review, consultation, and other actions required by applicable Federal environmental laws for this project are being, or have been, carried-out by TxDOT pursuant to 23 U.S.C. 327 and a Memorandum of Understanding dated December 9, 2019, and executed by the Federal Highway Administration and TxDOT.
