The USACE prepared the Trinity River and Tributaries Regional Environmental
Impact Statement (TREIS) because "...individually or cumulatively, these
projects [development projects in the Upper Trinity River watershed] were
felt to have the potential to compromise the existing protection afforded
to flood plain residents, because of perceived impacts to wetlands and
other natural resources, and because of competing public demands for other
uses of the river channel and flood plain, the District Engineer determined
that it was necessary to develop a regional perspective in order to properly
evaluate the impacts of individual permit decisions in accordance with
the spirit and intent of National Environmental Policy Act (NEPA)
and other applicable laws. In the Record
of Decision (ROD) for the EIS the USACE established strict criteria
to be met for Standard Individual Permts. These criteria have been
extended to Nationwide General Permits through a Regional
Condition. In response to the TREIS and ROD, the cities and
counties in the Trinity River corridor formed the Trinity River Steering
Committee, facilitated by the North Central Texas Council of Governments
(NCTCOG). The result was the establishment of the Corridor
Development Certificate (CDC) Process.
