On Monday March 16th, The City of Detroit will issue an Emergency Order to waterfront property owners in the Jefferson Chalmers neighborhood and surrounding properties affected by or threatened by coastal flooding in an effort to support mitigation of anticipated water levels in 2020 and threat posed to city infrastructure.

  • Beginning 3/16/2020, the City of Detroit Buildings Safety Environmental and Engineering Department will be addressing properties with conditions preventing access and installation of emergency measures.
  • Once a property is identified with conditions requiring remediation, the property owner will have 5 days to comply with the corrective action. 
  • If you have questions about your property, you can reach Donnie Wright, the District 4 BSEED Inspector at (313) 815-5542 or by email at [email protected].

Waterfront property owners can expect to see City of Detroit crews along with the US Army Corp of Engineers and subcontractors installing temporary barriers on public and private property beginning the week of March 30th.  These barriers are commonly known as Tiger Dams and have been recommended as a solution to support our continued efforts to prevent excess water from entering the combined storm water drainage system.  Other interventions may be used based on property conditions but Tiger Dams will be used predominately.  We expect to have this work completed by May 1 and there may be continued sandbagging efforts following this timeframe for a couple of weeks.

The presentation originally planned for the March 13th community meeting, which was cancelled due to public health precautions surrounding COVID-19, can be found on the city website at .  It gives and overview and description of the work outlined above.  There is also a link for submission of questions.

We strongly encourage occupants of waterfront and inland homes in the neighborhood to take the following measures immediately:
