Illinois Statutes Chapter 65. Municipalities § 5/11-110-1. Establishment and maintenance

§ 11-110-1. The corporate authorities of cities and villages for drainage purposes may lay out, establish, construct, and maintain drains, storm sewers, detention basins, retention basins and other “green infrastructure” facilities, such as green roofs, rain gardens, bioswales, tree boxes, porous pavement, porous pipe systems, native plantings, constructed wetlands, and cisterns, ditches, levees, dykes, pumping works, and machinery, and may acquire the necessary land and machinery therefor, and in this manner may provide for draining or otherwise managing the runoff, such as by infiltration, evapotranspiration, or collection, on any portion of the land within their corporate limits, by special assessment upon the property benefited thereby, or by general taxation, or a combination. No lot, block, tract, or parcel of land, however, shall be assessed more than once in any one year by a municipality for maintenance.
