Nonetheless, we headed to Home Depot to buy some sandbags to defend the house. The house's weak point is the steps that lead to the basement. If the nearby stream floods, our backyard ends up under water and it flows down the stairs to (and through) the basement door.
Home Depot was out of sand and sandbags, so I had to improvise. I bought weather seal foam and used scrap wood to make this storm wall.
The weather seal foam runs along the bottom to make what I hope will be a water-tight seal against the ground. Gratiutous use of duct tape helped seal up some holes.
The black hose runs to a sump pump which I hope will be enough should some water get past.
The whole thing ain't pretty, but I'm hoping it'll get the job done.
