1st major metro area to implement text to 9-1-1



In 1982, Commissioner Tom Bass was named by the Harris County Commissioners Court as its official representative in the 9-1-1 effort. During that same year, the City of Houston City Council task force recommended the creation of a special district for operation of 9-1-1 service for Harris County, with the placement of a service fee on the phone bills of telephone subscribers to fund the system. Lavergne Schwender of the County Attorney’s Office was principal author of the legislation and was later appointed as GHC 9-1-1’s Legal Counsel under an interlocal agreement with the County Attorney’s Office.

The 9-1-1 Emergency Number Act (Chapter 772, Health and Safety Code) passed the Senate on March 30, 1983, and passed the House on April 27, 1983. It was signed into law by Governor Mark White on May 10, 1983.

The Greater Harris County 9-1-1 Emergency Network was established in November, 1983, with the passage of enabling legislation and a voter referendum throughout the Harris County area. The voter referendum—to establish a communication district and assess a fee to fund the 9-1-1 service—passed throughout the Harris County area by a vote of 82.5% in favor.

The 9-1-1 system was officially cut-over by GHC 9-1-1 on January 26, 1986. The cities in Fort Bend officially became part of the GHC 9-1-1 Network effective September 1, 2005.
