Stormwater Flooding

We all know that heavy rain and snow can cause flooding. What we might not realize is that the flooding can be made much worse when the water from rain and snow runs off pavement, roofs and other non-absorbent surfaces. This fast runoff can overwhelm storm drains, causing street flooding, and quickly send streams over their banks.

Knowing where flooding can occur and avoiding construction of homes, businesses and more paved surfaces in those areas can help prevent serious flooding, property damage and risk to human life.

The Federal Emergency Management Agency provides floodplain maps to help you make purchasing and construction decisions. For floodplain maps of the Leawood area, visit msc.fema.gov/portal.
