Areas within the City of Glendale are located within the Floodplain. Floodplains are lowland area adjacent to lakes, wetlands and rivers that are covered by water during a flood. The most visible function of a floodplain is its ability to carry and store floodwaters. In Wisconsin, the primary cause of floods is excessive rain, snowmelt or a combination of the two.
One of the goals of floodplain management is to minimize the threat to life and property resulting from flooding. By promoting the preservation of floodplains for carrying and storing floodwaters and encouraging property owners to mitigate their flood risk by elevation, relocating, or otherwise flood proofing their structures.
Structures to be located in floodplains must not only be elevated above the flood protection elevation, but they must be placed so as not to diminish the ability of the floodplain to carry and store flood water.
Federal and State Government regulate the building of new, or altering existing structures in flood hazard areas throughout the United States. In Wisconsin, the Department of Natural Resources and local municipalities are charged with enforcement of the regulations. Municipalities must pass local ordinances adopting the Federal and State rules. Where there is substantial compliance with the rules, owners of properties within the flood fringe benefit by paying lower premiums for flood insurance that is subsidized by the National Flood Insurance Program.
