What does non-structural mean?
Response: To understand the concept of non-structural flood management methods, it is helpful to first look at the extremes. A structural solution to a flooding problem might consist of levees that confine flows to the main channel of the river or stream, a relatively deep detention basin, or an engineered channel designed for maximum flow. The extreme example of a non-structural flood management situation is a natural condition where there are no levees, and the river or channel overflows its banks repeatedly each year during the rainy season and is allowed to meander without any man-made restrictions. Any project that preserves existing natural periodic inundation of a floodplain or preserves a river’s ability to meander, or moves an existing structural situation in the direction of a more non-structural approach (such as setback levees) is eligible for funding under the Flood Protection Corridor Program, if it also provides for ecosystem preservation or enhancement, or agricultural
