To support TxDOT, Hollaway prepared a Biological Evaluation (BE) and conducted intensive habitat surveys (ground and drone technology) for the eastern Black Rail, Piping Plover, Rufa Red Knot, and sea turtle to support consultation with USFWS for a proposed revetment project near High Island and Anahuac National Wildlife Refuge in Galveston County, Texas.

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.
