Closes Creek Storm Sewer Improvements

Project Overview

As part of the City's plan to mitigate flooding in the Closes Creek Watershed, the City plans to continue to upgrade storm sewer infrastructure in this drainage basin. A stormwater drainage study was completed for this watershed in 2002, which established a prioritized list of recommended improvements. The City has completed improvements from Martin Luther King Jr. Parkway upstream to 30th Street as shown on the phasing map, Click here for Link. The City held a public meeting at the Northwest Community Center on December 11, 2018, to discuss the Maquoketa Drive Storm Sewer Box Replacement project. The City held another public meeting at Holy Trinity School on April 1, 2019, to discuss the 47th and Holcomb Storm Sewer Improvements project.

Project Status

The City is currently completing the Maquoketa Drive Storm Sewer Box Replacement project. This project provides a 12x4 concrete box culvert along Maquoketa Drive to replace the existing wooden box culvert which had structural issues and was undersized. The City is also currently nearing completion on the 47th and Holcomb Storm Sewer Improvements project. This project provides upgrades to the storm sewer system in the area providing a new outlet to the south. The primary function and benefit of the project provides underground storage of rainfall immediately upon completion and will provide detention for the entire watershed once the entire storm sewer system is completed. The current design will provide detention for the 25-year storm and will help mitigate the 100-year storm in the future upon completion of the entire watershed project.
