The Communications Subcommittee works with the City, local industry, police and fire dispatchers and the Deer Park
Independent School District to develop detailed procedures how to notify the City and warn the public in case of a chemical
release. The City's police and fire dispatchers have been trained how to handle calls from industry about a chemical release and how to quickly activate the City's emergency warning systems.
The City and local industry have invested in multiple, state-of-the-art systems to provide reliable and redundant warning to
homes, schools, businesses and visitors.
Nine siren-type alarms are mounted throughout the City, plus one at the Battleground State Park. The Outside Alarm System
is tested weekly at 12 Noon every Saturday. The system is only used for chemical releases or severe weather such as a tornado spotted in the Deer Park area.
