The City of Detroit is no longer asking for volunteers to help out over the next several days with filling sandbags and building barrier walls to help prevent further damage from flooding in the Jefferson-Chalmers neighborhood after hundreds of people signed up to assist their neighbors.

More than 320 people volunteered to help fill and distribute sandbags to the east-side neighborhood along the Detroit River or build barriers. Mayor Mike Duggan’s office expressed deep appreciation for the tremendous response.

Rising waters in Lake St. Clair and the Detroit River have breached seawalls in residential areas along canals near the river.

As of Thursday evening, volunteers and city employees were estimated to have filled 18,000 sandbags to help prevent further flood damage, and built 15 sandbag barriers throughout the neighborhood.
