Houston-Galveston Area Council Houston, Texas, USA By William Bass, GISP Contact William Bass william.bass@h-gac.com Software ArcGIS Desktop 9.2, SAS 9.1 Printer HP Designjet 1055 cm Over five million people live in the Houston-Galveston region today, and the population is projected to grow to over 8.8 million by 2035. A region of this size is continually evolving and developing to support the growing population. The Houston-Galveston region also contains over 4,500 square miles of floodplains. The intersection of people and floodplains produces a mixture of environmental and socioeconomic risks for the region. The analysis for this project was performed as part of a regional global climate change and flood hazards initiative. The analytical methods involved a combination of ArcGIS spatial analysis tools as well as analytical and data manipulation methods in SAS. The integration of ArcGIS and SAS allowed for a large amount of data to be gathered and processed. This map was one in a series that represented the culmination of the project’s efforts.
