Had the flood affected my current home, we would have been and continue to be in dire straights.
We have a basement under our split-level home, about 800 square feet of living and storage space, that is just over 5 feet below outside ground level--this would have totally filled with water.
Half of our basement houses the utility and storage room in the area under the lower portion of our main floor where the basement ceiling height is about 6 feet. This room is where we have our gas-fired forced air furnace and our electrical panel (gas meter and electric meter are on the outdoor foundation wall outside this room). This room is also where we keep our camping items, suitcases, and a few other seldom-used items under our stairs.
The rest of our basement is divided into a family room (two sofas, 3 bookshelves, our tv, and a closet where our kids' toys are stored plus our chest freezer in nook by the stairs), our spare bedroom (double bed, dresser, bedside table, upholstered chair, and a 2x8 foot closet full of canned and cold storage food), and a small bathroom.
All of this (food storage, furniture, books, toys, bedding & towels, freezer, furnace, tv, stored items etc.) would have been thrown out along with the carpet in the family room and bedroom, all of the drywall and insulation--down to 2x4 stud walls and metal posts holding up the upper stories. All of it. The electric panel would not be replaced/reconnected until demolition was complete and the space was dry.
We have hardwood floors on our main level, these would likely have needed to be torn out due to swelling. And if the water had extended above ground level, all flooring plus the drywall and insulation would need to be removed from the interior walls to a height at least a foot above the high water line. Same deal with our appliances and furniture on the main level--kitchen, dining room, laundry room, living room, powder room--everything would need to be thrown out. All we would be left with would be the contents of 3 bedrooms on the top level of our split-level home.
Had our car been trapped in our garage, as many were, it would not be fit for use--electronic components destroyed, upholstery full of mud and mould etc.
This is what the average home-owner in the city has dealt with/is still dealing with.
But in High River, the water got trapped in some neighborhoods for weeks and needed to be pumped out. So those houses, rather than just holding water for a few days, were under water for 3 weeks to a month and a bit more in some instances. The humidity throughout the home was super high during all that time, and those homes are full of mould on all levels--and very little inside those homes is salvageable. Many of those homes are or will be condemned and torn down.
So. Please pray (if that is something you do) for the people stuck in this nightmare. And please be thoughtful about how your own home is arranged. Where do you store your food? Your family photographs? Your first aid and emergency supplies? Your camping equipment?
Had we been evacuated, with enough time to pack up and leave in our car, we would have taken our camping equipment and photographs plus our first aid and emergency supplies, but everything else below ground (all my canning and cold garden storage) would have been lost. But if we had less than half an hour, or if the waters were already entering our home, we would have left with far less.
