Texas Architect January/February 2014: Ecologies
This issue on “Ecologies” explores urban design across Texas and focuses on the increasing importance of green infrastructure for our cities. With the rehabilitation of the San Antonio River, the state now has the longest linear park in the nation. Dallas is also leading urban design trends with its progressive parks plan — Klyde Warren Park is just one example of the good work being done. Houston and Austin are also both relying on green infrastructure to create valuable public spaces. Other important urban design initiatives featured include mixed-use development in downtown Austin, El Paso’s first net-zero senior housing project, and the push for San Antonio’s missions to be added to the World Heritage List.
Essay DALLAS I-35 I-45 AUSTIN HWY 71 I-35 HOUSTON SAN ANTONIO New Urban Tapestries by Frederick R. Steiner 36 Texas Architect 1/2 2014 I-10 are country and western. The reality of the state is that it is urban and becoming more so and, in the process, changing the concept of “western.” An estimated 85 percent of the 26 million Texans live in urban regions. Of the state’s total population, some 75 percent live in the Texas Triangle, one of the eleven fastest growing megaregions in the United States. The Texas Triangle is formed with Houston and San Antonio at the base, DallasFort Worth at the apex, and Austin in between. By 2050, around 30 million people, 70 percent of Texas’ projected population, will live in the four metropolitan areas that make up the megaregion. Between 2010 and 2050, the overall Texas Triangle will grow by 93.3 percent and reach over 38 million people. Outside the Triangle, the El Paso-Juarez Borderplex represents a significant urban conglomeration. As Texas has grown, ranch and farmlands around cities have disappeared along with valuable wildlife habitat. With the epic drought of the past few years, water has become scarcer, and many trees have died. In 2011, the state lost as much as 10 percent of its trees due to drought — that is, somewhere between 300 and 500 million trees. Wildfires have destroyed additional vegetation as well as buildings. Although Texas is energy-rich, the energy-water nexus The myth and image of Texas poses challenges. Increased energy use requires more water — and more water, especially hot water, increases energy consumption. Water use holds a fundamental key to the future of Texas. Abundant in the past, water provides ecosystem services largely taken for granted. The drought has altered this perspective. As a result, the green spaces within cities have become more valuable. We call interconnected open spaces that provide ecosystem services “green infrastructure” or “ecological infrastructure.” Ecosystem services are the things we derive from nature that have been traditionally viewed as free, such as the relative abundance of water historically in Texas, clean air and water, oxygen production, crop pollination, wildlife habitat, and the warmth of the sun. Green infrastructure helps to maximize the benefits of these services. of national and global urbanization trends and can be a leader with ecological responses in cities. Early in the 21st century, the planet became majority urban. In response, over the past several decades, new, innovative green spaces have been planned and designed. Around the world, the most compelling new landscapes transform previously abandoned and polluted sites. These efforts provide models for Texas.

As one of the fastest growing megaregions in the nation, the Texas Triangle has a crucial need for well-designed open spaces. Recent examples include Dallas’ Klyde Warren Park, Houston’s Buffalo Bayou Park, San Antonio’s Mission Reach, and Austin’s South Shore Waterfront.
