Floodplain Management

Flooding is a major natural disaster that occurs every year in the United States. Some floods cause only minor inconveniences and others cause complete devastation of an area. In either case, the City of La Crosse has several resources designed to keep its residents safe and allow them to get back to a normal way of life as quickly and efficiently as possible.

Substantial Damage or Improvement

The National Flood Insurance Program (NFIP) requires that if the cost of improvements to a building or the cost to repair damages (from any cause) to a building exceeds 50% of the market value (excluding land value), the entire building must be brought up to current floodplain management standards. Building improvement projects include exterior and interior remodeling, rehabilitation, additions, repair and reconstruction projects. 

Additionally, the cost of currently planned improvements will be added to the cost of previous improvements and compared to the existing market value to determine if the improvements exceed 50% of the structure's value. 

Please contact Building & Inspections at (608) 789-7530 for further information.
