June 25-26 Storm Event Analysis

A large storm, which dropped a tremendous amount of rain, occurred on the evening of June 25, 2021, into the early morning hours of June 26, 2021, resulting in numerous reports of flooding and basement backups in Washtenaw and Wayne Counties, including portions of the City of Ann Arbor. The rain was so significant that states of disaster were declared at the local, state and federal levels. Pittsfield Village and the surrounding neighborhoods on the southeast side of Ann Arbor were the most impacted areas in the city, although scattered flooding and backups were reported throughout the city.

The city has contracted with engineering consultant, OHM Advisors, to perform an engineering analysis to better understand the cause of the basement backups and flooding issues in the southeast part of Ann Arbor and provide recommendations on what, if anything, can be done to minimize the potential for similar occurrences in the future.


This project is proposed to be completed by the end of 2021, subject to change depending on the engineering analysis and the outcome of the public engagement process.

Work to be done

The Storm Event Analysis will include efforts to achieve a better understanding of the storm impacts within the project area and the flooding observations and experiences of community members. PublicJune 2021 Storm – Study Area_for Website.jpg meetings, survey/questionnaires, interviews, and other discussion opportunities will help the project team learn from community members. Engineering review will include a detailed analysis of stormwater and sanitary sewer systems and the system performance during this storm event. These efforts will help determine whether any recommendations could be pursued to minimize the risk for similar flooding and basement backup events in the future.
