1 - Mitigation Definition- Mitigation includes activities that: Prevent Reduce Lessen 1

2 - Community Mitigation - Manage developments within a flood plain Construct barriers Levees Berms Dikes - Community Mitigation - Consider raising buildings in flood plains Windows and doors should be above high water line - Building Mitigation - Install check valves in sewer traps 2

3 - Building Mitigation - Minimize electrical risk Use water tight electrical conduits and boxes Keep transformers high and dry or within a berm - Building Mitigation - Raise electrical services and equipment at least 12 inches above the 100 year flood line - Hazardous Material Facilities - Hazardous Materials Store on impervious pads Use dikes to protect Install pump and treat capabilities Protect sewers 3

4 - Hazardous Material Facilities - Underground and above ground storage tanks Ensure they are properly installed and anchored Keep tanks full Secure all openings Install shear valves Shut off power - Flood Insurance - Reduces the financial loss Guaranteed Administered FEMA Takes 30 days after purchase to go into effect Flood Insurance - Homeowners insurance and/or Property Insurance does NOT cover flood damage 4

5 - Preparedness: Supplies - Stockpile supplies Emergency building materials First-aid supplies Whistles Food Portable radio Flashlights - Preparedness: Water - Stockpile bottled water Store water in sinks/tubs Sanitize sinks/tubs using 10% bleach - Preparedness: Escape Plan - Learn the community s alert signals Obtain a copy of the flood evacuation plan Safest routes to shelters Local information on preparedness 5

6 - Preparedness: Escape Plan - Plan and practice an evacuation route Designate meeting area Develop emergency communication plan - Preparedness: Training - Training program should include: Response procedures Utilities shutdown Emergency services, 911 Radio station monitoring 6

7 - Flood Response - Secure outdoor possessions Household Lawn furniture Barbeque grills Recreational equipment Commercial/Industrial Material Storage Waster Outside equipment Vent lines - Prepare to Evacuate - Turn off all utilities at the main Electric, gas, and water Secure valuables (papers, expensive possessions, art work, and clothing) Upper floors or higher elevations Water tight containers Take evacuation items Rain gear Dry clothing Flashlight Whistle Battery-powered radio Follow emergency instructions - Prepare to Evacuate - 7

8 - When Not To Evacuate - If the waters start to rise prior to evacuation, retreat to higher elevations - When Not To Evacuate - Don t try to swim to safety Fast moving water Being struck by an object Polluted water Sickness Wait for rescuers - Evacuating by Car - Do not drive through a flooded area 18 inches of water can float a car Water can enter the engine 8

9 - Evacuating By Car - If approaching a flooded road Turn around Find alternate route If the vehicle stalls Abandon Climb to higher ground - Evacuating By Foot - Do not walk through flooded areas Look out for animals especially snakes Stay away from downed power lines and electrical wires Outdoors, climb to high ground and stay there - Emergency Management: Services - Provide temporary shelter for displaced people and pets Buildings Equipment Staffing Subsistence Clothing 9

10 - Emergency Management: Challenges - Loss of utilities Power Water Fuels Communications Transportation - Emergency Management: Challenges - Security Emergency Medical Treatment 10

11 - Recovery - Flood hazards continue even when water recedes Don t return home until it is safe Help those who require special assistance When applicable, file an insurance claim - Recovery: First Return - Enter the building with caution Inspect building first Pump out flooded basement gradually Walk carefully Control sources of ignition Keep the power off until inspected - Examples of Hazardous Materials - Drain cleaner Furniture stripper Motor-vehicle oil Toilet-bowl cleaner Antifreeze Pesticides Fertilizers Vehicle batteries Propane tanks 11

12 - Recovery: Steps to Take - Ventilate Reduce concentration of fuels Dry ASAP limit mold Inspect for mold growth - Recovery: Steps to Take - Check refrigerated foods for spoilage Confirm drinking water supply is not contaminated - Recovery: Steps to Take - Drinking water well contamination A major public health concern Contaminated any time the floodwater contacts well casing Test and disinfect 12

13 - Recovery: Final Steps - Review and revise your Flood Plan Reduce the risk of future floods Follow local building codes and ordinances when rebuilding Use flood-resistant materials 13
