Starting this Summer - 1st Avenue East Floodgate
The contract for the floodgate on 1st Avenue East was recently awarded and work is scheduled to begin in July or August. This will be a roller floodgate similar to the one already installed on 16th Avenue SE. Traffic impacts will not occur until after the Freedom Festival, and will include lane reductions and temporary parking removal. The project will be completed in 2022.

Ongoing - 3rd Avenue SE Floodgate
Work continues on the installation of the 3rd Avenue floodgate. This gate design will feature permanent columns with stackable, removable panels during a flood. 3rd Avenue SE remains closed while work is underway. Due to complications with site conditions and underground utilities, work is anticipated to extend into September 2021. There is no flood control work underway this year on 2nd Avenue SE.

Starting this Fall - Demolition of HydroElectric Facility at the 5-in-1 Dam
This facility has been out of service since it was damaged in the 2008 Flood. It will be removed and the dam gate behind it will be upgraded, which will allow for construction of a future floodwall between the dam and 1st Avenue East. Construction will begin this fall and be completed in 2022.
