Meydenbauer Flood Control Project

During extreme storms, there can be 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 twice caused flooding onto private property, causing damage and disrupting the community.

The address this recurring issue, the city will build a bypass pipeline to better convey stormwater during heavy rains. The project will also optimize the capacity of the existing storm drain system along 100th Avenue Northeast between Northeast Eighth and 12th streets.

Where is the project located?

The project is downtown, near Northeast Eighth Street and 100th Avenue Northeast. See map.

When will this work take place?

The anticipated project schedule is:

  • Spring 2020: Start construction
  • Winter 2020: Complete construction

What are the anticipated results?

The city anticipates that that the project will significantly reduce flooding in the area, without creating new flooding locations downstream. The project will greatly reduce flooding along 100th Avenue Northeast. By diverting storm flows southward, it also reduces flooding along Northeast Eighth.

How will the city mitigate the impact of construction site noise?

The city will communicate with residents and businesses in the vicinity of the construction site to provide them with information about what they can expect during the construction of the Meydenbauer Flood Control Project. This page will be updated on a regular basis to inform people about the weekend in which construction will take place.

How will the city mitigate the impact of street closures and lane reductions?

Detour routes will be posted when streets and sidewalks need to be closed. Check Traffic Advisories for the latest information about construction work that can affect travel on city streets and sidewalks.

Community Engagement

In the fall of 2019, the city will conduct outreach to condominium associations and apartments in the vicinity of the project. The city will also send out a flyer in the mail to residents and businesses that might be affected by construction.
