​Project completed and grand opening video released​

The City of Ann Arbor released video featuring Mayor Christopher Taylor, as a virtual commemoration marking the official grand opening and completion of construction on the $9.4 million Allen Creek Berm Project, capping the largest stormwater management and flood mitigation project in city history.

“I'd like to welcome you to this virtual grand opening of our Stormwater Smart campaign's Allen Creek Berm project," Taylor says in the video. “This is an incredibly exciting municipal project, multimillion dollar, years in the making. It addresses two really important municipal goals: stormwater and flood protection mitigation as well as promotion of non-motorized transportation," the mayor adds.

The city released the 90-second video instead of holding a traditional ceremony due to the COVID-19 pandemic. The video includes aerial drone footage and additional video that highlight the project's landscaping and safety improvements. For example, the Allen Creek Berm tunnel pedestrian pathway, in combination with new fencing, for the first time, provides
non-motorized users safe passage under the Amtrak railroad tracks. ​
