Identify the Risks
The vast diversity of our landscape means that every building within every community will have unique hazards. For coastal communities, the greatest threats may be from earthquakes, tsunamis or storm surges. For others, the threat may be from fires, floods, severe winter storms or industrial accidents. Experts say that if you are in doubt, you should plan for an earthquake, flood and fire. People who are prepared for these emergencies are equipped to deal with almost any disaster.
The following list contains natural and other hazards. Check off the risks that are most likely to impact your community. Take into account the areas in which you work, live and play.
__ Blackout (power outage)
__ Landslide or avalanche
__ Severe winter storm
__ Tornado or Hurricane
__ Earthquake
__ Tsunami or storm surge
__ Drought
__ Wildfire
__ Flood
__ Industrial accident
The type of “home” you live in will determine the steps you will need to take to make it as safe as possible. We’ll begin by taking a look at how your “home” is built.
Wood frame structures have greater survivability during an earthquake than non-reinforced masonry buildings but they are more susceptible to damage from fire or flood.
A structure that is anchored to the foundation can better withstand the forces of an earthquake, tornado or hurricane. How your home is anchored may depend on its age. Building codes have evolved over the years and newer homes are usually built so they can better withstand specific risks. Check to see if the cripple walls that extend from the foundation to the first floor of your home are exposed on the inside or reinforced with plywood. Reinforced cripple walls will provide greater stability during a disaster such as an earthquake.
How is your home constructed?
__ Wood frame __ Brick or masonry
__ Reinforced concrete __ Inside cripple walls reinforced with plywood
Is your home secured to its foundation?
My “home” __ IS secured to the foundation __ IS NOT secured to the foundation
If your “home” is not secured to the foundation, a structural engineer can tell you what type of reinforcing is possible. Ultimately, cost may be the deciding factor.
Knowing the type of ground beneath the foundation is also important. A structure that is built on bedrock has a much better chance of withstanding the forces of an earthquake, flood, or severe weather than one that is built on soft soil or till. Take note of where your “home” is located within the community. “Homes” built near the ocean or next to rivers leading to the ocean may be at risk from storm surges or tsunamis. “Homes” that are built below dams, next to rivers or in the forest may be susceptible to flooding or fire. If you live or work near a chemical plant this is also something to consider due to risk of spills.
