The SAFER (Sustaining Adequate Fire Emergency Response) grant application has been denied by FEMA.
The grant was supposed to provide $7.9 million in funding for the department.
This money would have been used to fund 39 positions within the Flint fire department.
According to city officials, without funding the city may need to make new cuts to it's fire personnel and stations.
City officials say losing support for it's department means ignoring how important a resource it is to the city.
"It's a great form of neglect" says City Councilman Wantwaz Davis.
"I think it's going to put us in a bad situation because now we are in a condition where we become vulnerable now".
Emergency Manager Darnell Earley said in a statement that while this is disappointing, it was not unexpected.
He says the city must now find a different way to fund the department.
