SH 45SW State FEIS, Record of Decision

Our firm was the environmental task leader for the controversial 4-mile new location freeway/turnpike in southern Travis and northern Hays counties. The Record of Decision was signed 20 months after publication of the Notice of Intent. This was a major achievement for a project of this size. CP&Y oversaw the preparation of the Environmental Impact Statement, including public involvement documentation.

We participated in regular technical workgroup meetings, with participation by numerous agencies and jurisdictions, including the U.S. Fish and Wildlife Service, the Barton Springs Edwards Aquifer Conservation District, Hays County, Travis County, the city of Austin, TxDOT, and the Central Texas Regional Mobility Authority (CTRMA).

The FEIS was completed under TxDOT’s supervision; however, the PS&E was completed under contract to the CTRMA. Early in project development, the schedule was accelerated from 36 to 24 months and then from 24 to 20 months. We worked with project partners to accelerate the project team’s deliverable schedule, while still ensuring that peer review and final review of each document was incorporated in the schedule.
