Abstract: The proposed invention is a flood and wind resistant building foundation. The building construction consists of an attached superstructure to a buoyant raft foundation with steel pipe anchor and bent steel plate guide assemblies attached at the foundation corners. The raft foundation is uniformly supported on grade during dry conditions, and on water during flood conditions. The corner anchor/guide assemblies resist wind forces during dry conditions, and provide lateral stability during flood conditions. The raft foundation has plumbing trenches and access space that permit continued use of the building utilities during a flood. This building is made with standard, light weight, low technology construction materials and products with a cost comparable to traditional construction.

Abstract: The proposed invention is the building design application of a foundation system that is flood and wind resistant. The foundation system consists of a building superstructure 1, foundation raft assembly 2, and steel pole anchor with bent steel plate guide assembly 3. The foundation raft assembly 2 typically bears on grade 4, but floats at water level 5 during a flood. The steel pole anchor with bent steel plate guide assembly 3 has a shaped bent steel plate that wraps around a steel pole anchor, and attaches to the foundation system corners.
