70 ILCS 2805/53

In levying any special assessment or special tax, each lot, block, tract or parcel of land shall be assessed separately in the same manner as upon assessment for general taxation, except that several lots or parts of land, owned and improved or listed in the warrant book as one parcel may be assessed as one parcel. However, this requirement shall not apply to the property of railroad companies or the right of way and franchise of street railway companies. Such property and right of way and franchise may be described in any manner sufficient to reasonably identify the property intended to be assessed.
