Comprehensive Flood and Stormwater Master Plan

Comprehensive Flood and Stormwater Master Plan

The Comprehensive Flood and Stormwater Master Plan pdf is the policy that guides flood management, stormwater drainage (detention, retention and sewers), and stormwater quality in the city. City Council approved an update to the plan in 2004.

Significant work has been completed since that time and a major flood event in September 2013 has influenced the public’s perceptions related to flooding. An update to the CFS will be initiated in 2018 to evaluate the following types of considerations: 

  • Climate change 

  • Floodplain, stormwater, water quality and groundwater regulations 

  • Floodplain mapping practices 

  • Prioritization of capital improvement projects 

The CFS update will include a public process to gather ideas and feedback from the community. The Urban Drainage and Flood Control District will also contribute funding and assistance.
