On Day 19 and 20, we worked on a threat matrix for a pressing issue, such as power failure. Today, we’re going to work on yet another one. If you have another pressing issue, make that threat matrix today. If there isn’t one, work on Flash Floods. This being a Michigan-centric column, flooding can be a threat most of us as heavy rains are common, as are rivers and lakes that will swell with the increased water volume. Some parts of Michigan are hilly, meaning even within a neighborhood, heavy water volume can affect us differently.
Task: Complete another threat matrix on another pressing threat, or if none, Flash Floods.
My article, Developing a threat matrix for Michigan families, goes into detail on how to make and use a threat matrix, and has a link to a sample threat matrix for your use.
In this case, severity of the storm effects can look like:
Elevated outside water: the least severe we need to be concerned with. This includes water accumulation on property that has little danger of damaging assets, such as a known low point in the yard that water will drain through.
Excess outside water is enough volume to affect property, either by washing away important items, such as landscaping effects, outbuildings, all the way to approaching the dwelling.
Destructive water levels are high enough to affect the house. This can include actual damage through water ingress into basements or living areas, as well as the inability of the house to drain away water (such as from a sump pump).
Structurally destructive water levels are strong enough to render a house completely unlivable, either through excess damage (such as severe water ingress or actual structural damage to the dwelling).
Remember, one threat can cause other threats to occur. Flash floods detailed on this matrix can cause a power outage, forcing the family to utilize two pages of their threat matrix. They at least then have the necessary procedures and tangibles in place to begin to address these multiple threats.
With these examples in severity, plan a pre-event mitigation, during the event emergency plan, and post-event recovery plan for each severity.
- Estimated cost: $0.
- Estimated time: 30 minutes
- Accomplishment: A matrix of how to pre-plan for a threat, actions to take during a threat, and post-threat recovery.
- Securing 2 liter water bottles and storing water. (5 min)
- Making notes on alternate daily drive routes. (5 min)
