Meydenbauer Flood Control Project

During extreme storms, the city has seen significant flooding in the vicinity of Northeast Eighth Street and 100th Avenue Northeast, which impacts people who live, work and shop in the area. In 2013, intense rainfall caused flooding onto private property on two separate occasions, causing property damage and disrupting the community. address this, 

To reduce this flooding, the city is constructing a bypass pipeline to better carry stormwater during heavy rains. The Meydenbauer Flood Control Project addresses will also optimize the capacity of the existing storm drain system on 100th Avenue between Northeast Eighth and 12th streets, and will replace the storm drain on the west side of 100th Avenue between Northeast 10th and 12th streets. The city anticipates that the project will significantly reduce flooding in the area, without creating new flooding locations downstream.
