Definition of Terms
“To improve the safety and well-being of the citizens residing and working in the City of Ada; and to reduce the potential of deaths, injuries, property damage, environmental and other losses from natural and man-made hazards in a manner that creates a disaster-resistant community, enhances economic development opportunities, and advances community goals and quality of life, resulting in more livable, viable, and sustainable community.”
“The primary goal of Ada Public Schools is to collaborate with the City of Ada and Pontotoc County in identifying potential natural hazards and developing mitigation action plans that would prevent or soften the impact of the identified hazards on school sites that comprise the Ada Public School District.”
“Particularly, Ada Public Schools would like to develop safe rooms/buildings to protect school communities from weather related hazards. These safe structures during non-emergency times could be used to enhance instruction, and provide much needed space for fine arts programs, student activities, spectator events, and community meetings.”
