Harris County was the first to establish a countywide district under the new legislation. The Greater Harris County 9-1-1 Emergency Network, following enactment of Article 1432c in May, 1983, was formed in November of that year. The service fee was instituted in April, 1984, and the system became operational in January, 1986. Following this example, other districts soon began to incorporate their efforts to institute developed 9-1-1 programs.
In 1984, the second emergency communications district law was passed during a special session of the Texas Legislature. Article 1432d, applying to counties with over 860,000 population, allowed Tarrant County to create a district in April, 1985.
A third law, authorizing the creation of emergency communications districts, was enacted by the Texas Legislature in 1985. Article 1432e applies to counties with 20,000 or more population, which allowed Galveston County to create a District in November, 1987. The service fee was instituted in 1988, and the system became operational in April, 1991.
In 1987, the 70th legislature passed Article 1432f, often referred to as House Bill 9-1-1 and later codified as Chapter 771 of the Health and Safety Code, which provides for a statewide approach to organizing and financing 9-1-1 throughout regional planning. Areas with existing systems had the option to remain independent or to be included in the regional approach.
