northwest edge of Kansas City, Kansas. The 1,500 acres are positioned in a setting of hillside
oak-hickory woodlands and lakeside sycamores. The 456 acre lake with marina was
constructed in the 1930’s by the Works Progress Administration.
Local Mitigation Concerns
• Flooding concerns for the planning area are not solely affected by the weather in
Kansas. As seen during the 2011 Missouri River Floods, events up stream can have
significant impacts on downstream communities. Montana had an unprecedented
snowfall and precipitation amount during the winter of 2010-2011, which caused flooding
in Region L. Levee breaches and over topping occurred frequently during this event,
affecting Leavenworth and Wyandotte Counties.
• Flooding is a hazard that can also contribute to soil erosion, landslides and land
subsidence. The impacts to transportation nodes, bridges, and industry along the rivers
are also at risk during flooding events, which can affect lives and property.
• Flooding concerns along Stranger Creek running North to South through the central part
of Leavenworth county which affects the cities of Eason and Linwood. Economic
development in this area is hampered due to flooding concerns.
• Significant flood and erosion issues are present along Indian Creek in Olathe.
• An issue in Johnson County is the upstream development impact on downstream
flooding. Historically, development does not account for downstream impact which
creates flooding issues where before there were none.
• Flooding can contribute to contaminated waters, especially standing water that can
cause public health concerns of infectious disease and bacterial illness. Cleanup of
these waters will require diligence also so that the responders are not infected.
• Flooding issues on the Kansas River, in and around the DeSoto Bottoms can
contaminate water wells that feed the Olathe Water production Center.
Development in the Hazard Area
Region L is the mostly densely populated area in Kansas, and is also the fastest growing. With
that growth comes the need for more housing, businesses, health facilities, etc. Floodplain
management practices must continue to be a priority to ensure that development is not
occurring in areas at risk to flooding. All of the counties in Region L participate in the NFIP, so
any development in the floodplain should be built according to its corresponding floodplain
management ordinance. Additionally, the jurisdictions that participate in the NFIP and the
Community Rating System (CRS) periodically review their floodplain management programs.
