Flood Response Planning

Kansas City, KS

Based on Benesch’s knowledge of the area’s flood protection system, the City of Kansas City, Kansas (KCK) engaged Benesch to prepare a Flood Response Plan that will allow the city to better plan, mitigate and manage the risks of flooding within the city due to flooding. Flood protection for the City is provided by an ever-increasingly complex system of levees, seepage wells, pump stations, flood gates and interior drainage structures. Since this infrastructure is owned and maintained by three public agencies, KCK, Kaw Valley Drainage District and the Fairfax Drainage District, as well as nearly half a dozen private owners, a comprehensive manual for the operation of this system does not exist. The document will serve as a guide to allow city staff to have easy access to the information necessary to manage the increasingly frequent challenges of flood events.

The scope of this project includes the identification, inspection and mapping of all infrastructure along nearly 22-miles of levee along both the Kansas and Missouri Rivers in the City. This includes identifying the service area (drainage area) for each pump station and gate, identifying any interconnections between the pump stations and/or gates, locating surcharge locations within the service areas, developing Action Levels, and reviewing gate closure schedules based on river gage readings, updating existing pump station Operations and Maintenance Manuals, and preparing mitigation plans for power failures, sink holes and other risk factors.

This document is being prepared to serve two purposes; provide an easy guide to flood management and response, as well as a detailed description of each flood control asset and its role in the overall protection system. The first guide will provide a straightforward response plan that will provide information on gate closures, pump station operations, and information that will allow staff to identify the causes of flooding behind the levees during highwater events. The purpose of this guide is to provide enough information to allow for the efficient operation of the flood control system, without bogging down the user in details that are not necessary during an emergency.
