The purpose of this Article is to establish a procedure for the creation and operation of special service districts. Special service districts will provide maintenance services peculiar to those districts, such as maintenance of greenbelt areas, landscaping on rights of way, maintenance of forest preserves and any similar service of special benefit to the residents of a particular area that are not normally provided, or not provided in the same degree to the remainder of the City. Special service districts may also be used for financing relatively small capital improvements and charging the district for the cost thereof by a special tax rather than creating bonded indebtedness.
