Currently, each charter township may make local or public improvements by, for example, paving streets; laying curbs and gutters, sidewalks, and storm and sanitary sewers; and installing solid waste disposal systems, water systems, and street and highway lighting. The township board may determine the necessity of the local or public improvement and may determine that all or any part of its expense will be defrayed by special assessment upon lands benefitted by the improvement. The bill would include the separation of storm water drainage and footing drains from sanitary sewers on private property for a public purpose, as part of these improvements.
