Trinity River Project

The Trinity River Project is a public works project undertaken in the 2000s in the city of Dallas, Texas, USA. Its goal is to redevelop the Trinity River. The project aims to turn the river's path into a collection of sports fields, trails, nature centers, and recreational opportunities. At 10,000 acres, it has been billed as the largest urban park in the United States.

History

Businesses and businessmen, like Ross Perot, Jr., have pushed in recent years to build a multi-million-dollar, landmark bridge over the river and convert the section of the river near downtown into a park area with nearby commercial and retail services somewhat similar to the River Walk in San Antonio or Lady Bird Lake in Austin.

In 1998, then-mayor Ron Kirk championed a new project that aimed to renovate the river through Dallas. Voters approved a bond proposal to fund a major cleanup of the river, construction of park-facilities, wildlife habitats, flood-protection devices such as levees, and related road construction. Once passed, a planning process began with construction on the project starting in 2005. Proponents believe this development will bring more life, commerce, revenue to the downtown Dallas region.

On December 12, 2005, construction on the Margaret Hunt Hill Bridge began — the bridge is one of three Santiago Calatrava-designed bridges to be constructed as part of the project.

Upon completion, it will connect Woodall Rodgers Freeway in downtown to Singleton Avenue in west Dallas. The cable-stayed bridge is to cost $93 million, its total length will be convert|570|m|ft|0|sp=us|lk=on with a main-span of convert|365|m|ft|0|sp=us, and an apex-height of convert|122|m|ft|0|sp=us.

Components

The Trinity River Corridor Project has been billed as a threefold venture: one that seeks to protect downtown Dallas against future flooding, to improve transportation through the congested downtown district, and to provide a place of relaxation and play for downtown residents who currently have limited outdoor recreational opportunities.

Flood Protection

Although rare, downtown Dallas has suffered severe flooding in decades past (most severely in 1908 but also in 1990 and several times in between) and the Trinity River Project has enlisted local and government officials for advice on extending and improving the current levy system protecting the downtown area.

Following the 1908 flooding of the Trinity basin, levees were first constructed in 1932 and then extended in 1960 to the height they stand at today (30 feet).

Current plans to improve the existing levees are part of what is known as the Dallas Floodway Extension project, and entail extending two existing levees and raising two others, all adjacent to the downtown Dallas area.

A second component of Dallas' efforts for further flood protection involves the construction of a series of wetlands within the Trinity basin; these wetlands are being constructed to divert excess water away from the Trinity, further reducing flood danger. Currently, two sections of wetlands are being constructed, an Upper Chain and a Lower Chain, with the latter being almost complete as of Spring 2008.

Transportation

The Trinity River parkway, the most controversial portion of the project, is a proposed nine mile parkway located inside the river levees but above the floodplain that would provide an alternate route for Dallas residents and business travelers and relieve intense Dallas highway traffic. [ [http://www.trinityrivercorridor.com/pdf/vision_plan/VisionTransportation.pdf] -Retrieved on May 24 2008.] Under the direction of Dallas officials, the North Texas Tollway Authority (NTTA), and the Texas Department of Transportation (TxDOT), the tollway is being constructed on the side of the Trinity closest to downtown and will accommodate four lanes of traffic with some sections possibly expanded out to six lanes; the parkway is set to cost approximate eighty five million dollars with construction beginning in 2010 and running through 2014.

Recreation

The Trinity River Project incorporates several new recreational developments aimed at improving quality of life for downtown Dallas residents and visitors. These include: an Audubon center, a set of new trails for biking, hiking, and walking, parks, a standing wave, sports complexes, a horse park, and two manmade lakes. [ [ http://www.trinityrivercorridor.com/pdf/TimelineRecreation.pdf] -Retrieved on May 24 2008.]

These amenities are set to be added to various areas adjacent to downtown Dallas. The two lakes, named the Urban Lake and the Natural Lake by project officials, are set to be built in line with the Dallas cityscape so that cars crossing the aforementioned bridges pass over the lakes before entering downtown.

The project also contains a 40,000 acre impact zone for economic developement along the Trinity River. It will include retail, restaurants, residential developements, office, and also attract business into the city.

Currently there exists a broad section of developed land between the skycrapers of downtown and the water's edge of the Trinity and the two lakes. Recently, Dallas city hall has put forth new zoning laws concerning this area; this new legislation redefines the types of structures that can be built in this area and extends downtown's sphere of influence with its model of highrise and high density construction out to the Trinity river.

Criticism

Although the original bond proposal was passed in 1998, work has progressed slowly.

A proposed toll road has garnered significant criticism from community activists. The 1998 bond proposal for the project allowed for a "parkway" within the project area. By 2007, Dallas business and political leaders had convinced the city to plan for a six- to eight-lane tollway that would link the suburban North Dallas area to southern-bound freeways with no entrance or exit ramps near the park. Following a requirement by the Army Corps of Engineers to move the road into the proposed park area, city councilwoman Angela Hunt and local activists argued that the road would cripple the planned development; tollway supporters pointed to the planned roadway's ability to decongest the undersized "Mixmaster" interchange between I-35, I-30 and Central Expressway, and argued that attempting to move the road would require a cost-prohibitive exercise of eminent domain. In a referendum sparked by Hunt, voters approved the construction of the toll road, thanks primarily to voters in the suburban north end of the city.

Progress

The Margaret Hunt Hill Bridge, the largest portion of the Trinity project started thus far, is currently being built and set to be complete in 2010. The Margaret McDermott Bridge, the second signature bridge, will begin construction in 2011 with a completion date of 2014. The Trinity River Audubon Center has been under construction for close to one year and is set to be completed in fall 2008. The set of trails and parks included in the project have varying start and end dates: for most, construction has already begun or will begin this year and is set to be complete in 2009. The standing wave will also begin construction in 2008 with a completion date of spring 2009. Both the sports complex and horse park are slated to break ground in 2009 with completion dates of 2010 and 2011 respectively. The two lakes are scheduled to begin construction in 2011 with an opening date of 2014.

Purpose

Both supporters and critics of Trinity River Project agree that the Trinity river itself is a vital resource of the Dallas community that has gone unused and neglected for decades. Dallas was first founded on the banks of the Trinity, and the river is tightly interwoven with Dallas' history, yet in its current state is largely hidden from public eye.
