Building IN a Flood Plain?
Does anyone here have experience building IN a floor plain?
Our house is on an acre directly west of a narrow but deep-cut water course. It was a creek until it was dredged in the late 1800's. In summer you could cross it without getting your ankles wet, but in spring and winter it can rise to the level of the bridge across it and is a raging torrent. The SE corner of our lot is designated flood plain.
Immediately east across the bridge sits a house that is now on two acres. Over twenty years ago that owner subdivided his lot, creating another acre+ flag lot behind his house, bordering the water course. Most of the flag lot is under water whenever there's a storm. (Neighbor kids kayak the 'lot'. Today that lot could not be sold as a buildable lot.
An unfortunate couple have owned the flooding flag lot for all those years. They've tried to either get a permit to build or to sell the lot -- no dice. Now before our city's Building Review Board is their latest proposal.
They propose to build a two story, 6000 sq ft all brick Italianate house that will rest on a five-foot deep brick water-storage foundation. The foundation is designed with vents to allow flood water into the foundation, retain it, then discharge the water as the water course goes down.
Most of us neighbors think this is a bizarre and dangerous idea. I envision the stuff that is in the water when it is in flood stage (tree limbs, animal remains, plastic, glass, etc.) smashing into this foundation, creating a dam against it, resulting in flooding upstream -- and breaking the foundation itself.
I've never seen such a design. Have you?
I don't oppose "A House" on the property. Something on stilts could be quite striking and allow water to flow freely underneath. Such a house would work with the existing site. This design seeks to alter the site (and the water course) to build a completely incongruous design. I'm very afraid this will get built and we'll ALL be sorry.
