Austin is one of America’s fastest-growing cities. This growth has brought dynamism to the city, but has also created environmental problems. Because much of Austin’s growth has taken place at the urban fringe, the addition of new residents and businesses has caused persistent and worsening problems with traffic congestion, air pollution and water quality, as more undeveloped land is converted into new development. To accommodate the continued influx of new people to the city, Austin is currently revising its land development code in a process called CodeNEXT. This revision seeks to house a growing population in ways that minimize the increase of developed land. Compact development can deliver tangible benefits for the environment – reducing energy use and greenhouse gas emissions, curbing the flow of polluted runoff into streams and lakes, and protecting natural areas and agricultural lands. By adopting strong policies to mitigate the local impacts of greater density, such as green infrastructure to manage stormwater, Austin can develop in a way that will bring lasting environmental benefits.
