Under the Disaster Mitigation Act of 2000, cities and counties were required to develop Mitigation Plans for their jurisdictions. The Gateway ADD, working with the local elected officials, chambers of commerce, industrial authorities, citizens at large, local media and health departments have devised a plan to mitigate, or lessen the impact, to the Assets and Critical Facilities of the Gateway Region due to Natural Hazards.
Assets are defined as residential buildings (houses), commercial buildings (businesses), religious buildings (churches), industrial buildings (manufacturing facilities), educational buildings (schools), governmental buildings (city halls and courthouses, detention centers) and agricultural buildings (stockyards, farmers markets).
Critical Facilities are defined as major roads and bridges, airports, water and wastewater treatment plants and pipelines, water storage tanks, pump stations, communication towers, oil and natural gas facilities, dams and levees and health care facilities,
Natural hazards can be defined as floods, ice storms, tornadoes, earthquakes, wildfires, landslides, severe winter storms, etc.
The Gateway ADD Regional Hazard Mitigation Plan was completed and approved by FEMA on 2006 and 2012 and is due to be revised in the upcoming months in time for the revision to be approved in 2018.
