The Dallas Floodway Extension (DFE) is a joint project of the City and the U.S. Army Corps of Engineers (USACE) to develop a 1,400 acre "Chain of Wetlands" extending from Corinth Street to Loop 12 and to build 20-21 foot protective levees along Lamar Street and Cadillac Heights, linking existing levees from the Central Business District to the Rochester Levee on the east, and extending a levee from Cedar Creek to the Central Wastewater Treatment Plant. These improvements will increase the level of protection for the Central Business District and Rochester Park from the 300-year event to the Standard Project flood (800-year event).

The protection for the Lamar area and Cadillac Heights will be the Standard Project Flood 800-year event. These levees will protect 440 existing structures from recurrent flooding, preserve 1,675 jobs in the Lamar Street area, and increase flood protection for the Central Wastewater Treatment Plant to the 500 year flood event. It will also realign the Trinity channel at IH-45, a National Defense Highway, to protect the bridge structure. Excavated material from the wetlands will be utilized for construction of the levees, for construction of the Trinity Parkway, and for increasing the height of the existing Rochester Levee for a distance of approximately 1,000 feet. The project will provide environmental restoration/mitigation for levee and Parkway construction, and will provide for recreational facilities and trail linkages between the Great Trinity Forest, the Trinity Park, neighborhoods and high employment areas.

The Elm Fork Levee is a joint project of the City and the U.S. Army Corps of Engineers (USACE) for development of a six-mile levee of 15-18 feet in height extending generally along Luna Road from Royal Lane to the vicinity of California Crossing and east to Bachman Lake. The levee system will provide Standard Project flood protection to 800 acres of floodplain within the Stemmons North Industrial District and 600 existing structures valued in excess of $700 million. The levee will utilize material excavated from the "Chain of Lakes". Regional trails for transportation and recreational use will link neoghborhoods and high employment areas.

The Trinity Corridor Transportation Improvements are a joint project of the City of Dallas, the Texas Department of Transportation (TxDOT), and the North Texas Tollway Authority (NTTA). The project will provide funding for City participation in the Trinity Parkway, a 6-8 lane reliever route extending from U.S. 175 on the east, constructed as a one-way couplet within the Dallas Floodway levee system and extending west to connect with S.H. 183 in the area of IH-35E and for expanding Beckley Avenue to a six lane divided thoroughfare from Singleton Boulevard to one block east of IH-30. This project is under consideration by the North Texas tollway authority for development as a toll facility. The construction of the Trinity Parkway reliever route will permit TxDOT to complete improvements to IH-30 and IH-35E (Canyon/Mixmaster/lower Stemmons), including frontage roads, a direct connector between IH-30 and IH-35E, High Occupancy Vehicle (HOV) lanes, elimination of unsafe conditions, installation of intelligent vehicle systems, and the expansion of lanes in the Canyon within an accelerated fifteen year schedule. The project will extend Woodall Rodgers, as a key element of the reliever, across the Trinity River to Singleton/Beckley Avenue, providing access to the Trinity Parkway, West Dallas, and Oak Cliff.

The Great Trinity Forest will implement the Great Trinity Forest Master Concept providing for the development of the Trinity Interpretive Center, an equestrian center, equestrian and nature trails, and multi-purpose trails to be used for recreation and transportation, boat launches, and trailhead improvements. It also provides for the acquisition and preservation of 2,700 acres of pristine bottomland hardwood forest within the Trinity River Corridor. The Forest is the most likely site recipient for environmental restoration/mitigation required for the Trinity parkway, the Dallas Floodway Extension Project, and other transporatation projects in the Dallas area.

The Chain of Lakes will create a series of lakes within the Dallas Floodway upstream of Corinth Street and extending to the confluence of the Elm Fork and the West Fork of the Trinity River. The lakes will increase the Floodway's capacity for floodwater conveyance, will mitigate the effects of the construction of the Trinity Parkway, and will provide material for the construction of the Trinity Parkway and the Elm Fork Levee, as well creating recreational amenities within the Dallas Floodway. Trail linkages for transportation and recreational use will connect neighborhoods and high employment areas in Oak Cliff, West Dallas, and the Central Business District.
