Part of: Optimizing the Resources for Water Management


Since 1985 the Corps of Engineers has reviewed Section 404 permit requests in regard to hydrology and hydraulic impacts of developments in the mainstem floodplains of the Trinity River in the Fort Worth-Dallas Metroplex. A Regional Environmental Impact Study with multiple alternative mainstem floodplain development scenarios indicated very significant negative cumulative impacts on downstream land uses. Development of a significant part of the mainstem floodplain can occur without a Corps permit but does require approval of local governments. Local political entities are considering implementing a permit process in cooperation with the Corps for the entire mainstem floodplain.
