2019, following a federal court ruling on homelessness sleeping in public, the Austin City Council lifted a 25-year-old ban on camping, sitting, or lying down in public unless doing so causes an obstruction. The resolution also included the approval of a new housing-focused shelter in South Austin. In early October 2019, Texas Governor Greg Abbott sent a letter to Mayor Steve Adler threatening to deploy state resources to combat the camping ban repeal. On October 17, 2019, the City Council revised the camping ordinance, which imposed increased restrictions on sidewalk camping. In November 2019, the State of Texas opened a temporary homeless encampment on a former vehicle storage yard owned by the Texas Department of Transportation. In May 2021, the camping ban was reinstated after a ballot proposition was approved by 57% of voters. The ban introduces penalties for camping, sitting, or lying down on a public sidewalk or sleeping outdoors in or near Downtown Austin or the area around the University of Texas campus. The ordinance also prohibits solicitation at certain locations. Economy The Greater Austin metropolitan statistical area had a gross domestic product (GDP) of $86 billion in 2010. Austin is considered to be a major center for high tech. Thousands of graduates each year from the engineering and computer science programs at the University of Texas at Austin provide a steady source of employees that help to fuel Austin's technology and defense industry sectors. The region's rapid growth has led Forbes to rank the Austin metropolitan area number one among all big cities for jobs for 2012 in their annual survey and WSJ Marketwatch to rank the area number one for growing businesses. As a result of the high concentration of high-tech companies in the region, Austin was strongly affected by the dot-com boom in the late 1990s and subsequent bust.
