Project Updates

DES MOINES, IOWA — Thursday, December 5, 2019 – Just over a year after the flash flood of June 30, 2018, two large stormwater construction projects are underway in the Beaverdale Neighborhood.  Work crews recently hit the streets to start construction on a $6 million stormwater project in the area of 47th Street and Holcomb Avenue.

This project will provide increased stormwater conveyance capacity as well as underground stormwater detention.  Construction started in October on the $7 million Maquoketa Drive Storm Sewer Box Replacement which includes construction of a new 12-feet by 4-feet reinforced concrete box culvert which will replace an existing 5-feet by 4-feet wood box culvert. 

“We’re excited to accelerate stormwater improvements in the Closes Creek Watershed and mitigate flooding in this area which suffered significantly during the summer of 2018,” said City Engineer Steve Naber. “These improvements enhance stormwater conveyance through the watershed and provide detention to store stormwater runoff and discharge it at a slower rate to mitigate flooding in the area and downstream.”

Both projects are part of the overall plan to improve stormwater management in the Closes Creek Watershed. City leaders programmed $145 million to flood mitigation and stormwater improvements throughout Des Moines over the next six years, nearly tripling the amount spent annually the previous decade.
