Communities covered from Dearborn to Canton

Ferndale is, because it sits within 25 km of Dearborn even though it is in Oakland County. Nearly everything else on the list is in Wayne County. Canton is a township rather than a city. Farther-out places such as Ann Arbor and Pontiac are beyond the radius, so call to confirm anything near the edge.

Some Detroit neighborhoods are: Warrendale, Southwest Detroit, Brightmoor and Far West Detroit all fall inside the 25 km circle and have their own pages. Others farther east or north do not. If your address is in Detroit, give the nearest cross streets when you call and you will get a clear answer.

Mostly the drainage behind them. Some places sit low along Ecorse Creek or the Rouge, others rely on older combined sewers that surcharge in heavy rain, and others are newer subdivisions with their own storm sewers. That is why each page names its own creek, drain and housing era instead of repeating one script.

The Detroit Water and Sewerage Department program is for Detroit addresses only, so it does not cover Dearborn or the suburbs. The protection program guide explains who qualifies and what residents elsewhere can do, such as asking their own public works office.
