  • State Highway 99 Segment I-2 Cedar Bayou Bridge

    Hollaway worked closely with TxDOT’s contractor to meet restoration obligations under a Clean Water Act (CWA) Section 404 permit, as construction activities resulted in a severed hydrological connection to a large wetland complex (causing it to dry up). Hollaway facilitated negotiations between TxDOT, USACE, and the contractor to identify a solution that met the spirit of the CWA. Hollaway quickly designed, obtained approval for, and implemented a Voluntary Restoration Plan that restored and enhanced three forested wetlands.
