Benton Avenue to N Main Storm Sewer Improvements

The Purpose

With the passage of Proposition P in 2016, several storm water projects were prioritized across the City. This project will alleviate street and property flooding due to an inadequate storm sewer system. 

Improvements

  • Large pipes and storm drains will be constructed to collect more stormwater
  • The flood gate structure will be replaced near Missouri River. The flood gate will close during river flood events to prevent floodwater from backing up in the storm sewer system. 
  • Aging water mains will be replaced

Please Note: Temporary lane closures should be expected on some streets during this construction. At least one lane of traffic will be maintained during construction to provide access to all residents and businesses. A section of the Katy Trail will be closed temporarily and a detour route will be provided along N. Main Street. 

Construction is anticipated to start Fall of 2020 and expected to be complete by the end of 2021.
