Regional Growth

Because of concern that potential cumulative impacts could not be adequately assessed through individual permit reviews, the Fort Worth District of the Corps and NCTCOG launched a regional initiative that is still going strong a decade later.

In 2005, it's current population of approximately 6 million is greater than 35 states. To assure an adequate long-term drinking water supply, each of the major branches in the upper watershed has been impounded with manmade reservoirs. Thus the Trinity River as it flows through the urban core faces great extremes, with low flows composed almost totally of treated wastewater to massive floods with the potential for billions of dollars in damages and untold loss of life across its 240 square mile floodplain.


The North Central Texas Council of Governments (NCTCOG) is the voluntary association of more than 200 cities, counties and special districts in a 16-county region. NCTCOG is an association of, by and for local governments. NCTCOG assists its members in planning for common needs, cooperating for mutual benefit, and recognizing regional opportunities for improving the quality of life.

NCTCOG is the designated regional planning agency for comprehensive planning as well as functional programs such as solid waste, mobile source air quality, and water quality management. NCTCOG has actively addressed key water resources issues since developing the first areawide water quality plan approved by the U.S. Environmental Protection Agency in the nation. Besides sustaining the areawide water quality planning process, NCTCOG coordinates one of the largest urban storm water programs in the country. Most particularly, NCTCOG serves as local sponsor for the U.S. Army Corps of Engineers' largest floodplain feasibility study. This process has evolved through three major steps:

  • Regional EIS which demonstrated need for common approach to flood plain management
  • Reconnaissance Study which identified potential flood damage reduction alternatives
  • Feasibility Study addressing flood damage reduction, recreation, water quality, environmental enhancement and coordination of other regional issues in the corridor
