Before an authority sets or revises rates, fees, or other charges for stormwater management programs and structural or natural stormwater and drainage system service, the authority shall hold a public hearing on the matter. At least seven days before the hearing, the authority shall publish notice of the public hearing in a newspaper having general circulation in the area. An authority may impose rates, fees, or other charges for stormwater management programs and stormwater and drainage system service on a person even though the person has not entered into a contract to receive the service.
Rates, fees, and charges shall be fixed and revised so that the revenues of the authority, together with any other available funds, will be sufficient at all times:
The fees established under this subsection must be made applicable throughout the service area. Schedules of rates, fees, charges, and penalties for providing stormwater management programs and structural and natural stormwater and drainage system service may vary according to whether the property served is residential, commercial, or industrial property, the property's use, the size of the property, the area of impervious surfaces on the property, the quantity and quality of the runoff from the property, the characteristics of the watershed into which stormwater from the property drains, and other factors that affect the stormwater drainage system. Rates, fees, and charges imposed under this subsection for stormwater management programs and stormwater and drainage system service may not exceed the authority's cost of providing a stormwater management program and a structural and natural stormwater and drainage system. The authority's cost of providing a stormwater management program and a structural and natural stormwater and drainage system includes any costs necessary to assure that all aspects of stormwater quality and quantity are managed in accordance with federal and State laws, regulations, and rules.
No stormwater utility fee may be levied under this subsection whenever two or more units of local government operate separate stormwater management programs or separate structural and natural stormwater and drainage system services in the same area within a county. However, two or more units of local government may allocate among themselves the functions, duties, powers, and responsibilities for jointly operating a stormwater management program and structural and natural stormwater and drainage system service in the same area within a county, provided that only one unit may levy a fee for the service within the joint service area. For purposes of this subsection, a unit of local government shall include a regional authority providing stormwater management programs and structural and natural stormwater and drainage system services.
