Definition of Terms
  • Hazard Mitigation is defined as:
  • Sustained actions taken to reduce or eliminate long-term risk to human life and property from natural and technological hazards and their effects.
  • Note that this emphasis on “long-term” risk distinguishes mitigation from actions geared primarily to emergency preparedness and short-term recovery.
  • The scope of the City of Ada and Ada Public Schools Multi-Jurisdictional Multi-Hazard Mitigation Plan is citywide.
  • It addresses all natural and man-made hazards deemed to be a threat to the citizens of Ada.
  • Both short-term and long-term hazard mitigation opportunities are addressed, beyond existing federal, state, and local funding programs.
city of ada goals
“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.”City of Ada Goals
ada public schools goals
Ada Public Schools Goals

“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.”

Canadian Sandy Creek flows north along the east boundary of Ada into the Canadian River. Ada is currently studying the feasibility of building Scissortail Dam on the Canadian Sandy, about 1 mile west of the city. Flowing into the Canadian Sandy from Ada are Little Sandy Creek and the west-flowing Tributaries 1, 2 and 3.

Clear Boggy Creek. All of the streams on the south side of Ada flow into Clear Boggy Creek, which drains an area of 10 square miles. The creek flows southeast into the Muddy Boggy, near Jasper, and eventually into the Red River. Tributaries of Clear Boggy Creek are Lake Creek, Clear Creek, and Tributaries 1 and 2.

Muddy Boggy Creek flows east from the eastern fenceline of Ada and then south into the Red River near Hugo.
