Corridor Development Certificate Program
The Corridor Development Certificate (CDC) process aims to stabilize flood risk along the Trinity River. The CDC process does not prohibit floodplain development, but ensures that any development that does occur in the floodplain will not raise flood water levels or reduce flood storage capacity. A CDC permit is required to develop land within a specific area of the Trinity floodplain called the Regulatory Zone, which is similar to the 100-year floodplain.
Under the CDC process, local governments retain ultimate control over floodplain permitting decisions, but other communities along the Trinity River Corridor are given the opportunity to review and comment on projects in their neighbor’s jurisdiction. As the Metroplex economy continues to grow and develop, the CDC process will prevent increased flood risks.
As an effort requested of the North Central Texas Council of Governments (NCTCOG) by its members associated with enhancing the Trinity River Common Vision program’s administration, a new CDC tracking method and model storage system has been developed and launched October 1, 2020. The new website, www.trinityrivercdc.com is now the location to access documents and information about the CDC program.
