Stormwater Construction Set to Begin on 9th Avenue

Do you live or travel near 9th Avenue and 12th Street?

As soon as Monday, September 21, the block of 9th Avenue between 11th and 12th streets will close for several months while crews install new stormwater infrastructure.

Have Concerns?

If you live or regularly travel in the area, we want to hear from you. Let the project team know about regular deliveries, property access needs, scheduled services or other concerns we should be aware of during the closure by emailing InfrastructureComms@thelevel5.com.

What is Being Done?

The work area is tight, and the stormwater structures are too large to install as pre-cast pieces. Instead, crews will build the structures on-site. This construction approach will create more durable structures that provide a long-term solution for downtown infrastructure needs.

Building the system in place will also help reduce project costs. Once complete, the project will help reduce downtown flooding and support future development by improving the City’s water, sewer, and stormwater infrastructure.
