Just one inch of water in a 2,000-square-foot home can cause $21,000 in damage.
That startling fact, courtesy of the National Flood Insurance Program is something to keep in mind about the trauma of flood damage and loss in Boulder, Colo. Many residents there had much more than an inch of water. One anonymous posting on the city’s flood website reported that 7.5 feet of water poured into the finished basement. Everything was lost, the resident said.
Of course, not everyone had 90 inches of water lapping at the basement walls. A homeowner might have had an inch of water while a neighbor had several feet. Some with crawl spaces had little or no water while others with crawl spaces are still pumping out. Others saw water leak in from the roof, too.
It’s seems like a head-scratcher but there’s some logic to it. The position of homes, how and where storm drains back up, positioning and diameter of gutters and downspouts, types of foundation waterproofing, and whether there are flood vents in basements and crawl spaces are just some factors that affect a flood’s impact.
Neighbors Michael Leccese and John Pollak learned firsthand about the vagaries of nature’s impact.
Leccese’s home has a crawl space about three feet below the ground floor. A tiny furnace room sits deeper at what would be basement level. The crawl space remained dry but about an inch of water seeped into the furnace room, which took Leccese an hour to remove with a wet vacuum.
Pollak had only a small amount of water in his crawl space. But the basement of his rental triplex took in more than two feet of diluted sewage. He gutted the basement, removing drywall, carpeting and anything else 2.5 feet above the floor. When the doors kept leaking, he realized that their hollow cores acted like straws that couldn’t contain all of the water they had absorbed. So the doors were removed, too.
Here’s what Leccese and Pollak would like you to know from their experience:
- Install concrete flooring in the basement instead of wall-to-wall carpeting.
- Inspect the roof regularly.
- Get a sump pump. If you’ve already got one, service it and check it during storms or flood alerts.
- Consider flood insurance. Don’t assume you’re OK because flood maps say you’re not in the flood zone. Some flooding was the result of rising water tables, rivers and creeks that found new courses, debris that created dams, overflowing irrigation ditches, mudslides and drain overflows.
- Check the waterproofing of your home’s foundation.
- Install larger diameter downspouts and gutters, and extend the downspouts farther away from the house.
- Know what your homeowners insurance covers. Will damage from backed-up drains be covered or will your insurer refuse because it’s a flood?
- Consider installing drywall several inches above the floor and covering the gap with base trim. That way, the drywall won’t start slurping up the water until you’ve got several inches.
