The Emergency Services Corporation (ESC) was developed in 2003, initially as a way to more effectively manage and share costs for EMS services within Rockwall County. It was born of a desire to ensure oversight on the level of patient care, response times and excellence in service. Since 2004, EMS service in Rockwall County has been contractually provided by an ambulance service with oversight by the ESC board. Board members of the ESC include elected officials from Rockwall County and the cities of Rockwall, Heath, Fate, McLendon-Chisholm, Royse City, Rowlett and Mobile City.
The ESC is a local government corporation that has also addressed other health and safety-related issues over the years on a cost sharing basis. For example, the ESC is the umbrella organization that built and manages the law enforcement training facility that enables local, sworn peace officers to train and stay current on requirements for carrying their firearm(s). Also part of the ESC is a countywide Emergency Management program which employs two staff members who assist jurisdictions throughout Rockwall County with emergency preparedness, planning, training, exercises, and grants.
