(605 ILCS 5/9-115)
(from Ch. 121, par. 9-115)
It is unlawful for any person to excavate or remove or cause
the excavation or removal of the lateral support within a distance of 10
feet plus one and one-half times the depth of any excavation adjacent to
the established right-of-way of any public highway located outside the
corporate limits of any municipality, except that if any of the excavated
materials be of solid rock, the depth of such solid rock shall not be
considered in computing the limit of excavation from such right-of-way line
of such public highway.
It is unlawful for any person to deposit spoil or cause the spoil from
any excavation to be deposited in such a manner that the toe of such spoil
will be nearer than 20 feet to any established right-of-way of any public
highway located outside the corporate limits of any municipality.
Whenever any person violates or causes the foregoing provisions of this
Section to be violated, he shall be guilty of a petty offense for each day
such violation occurs and until such unlawful excavation is backfilled or
unlawful spoil banks are removed, either by the offenders or by the public
authorities as provided hereinafter in this Section.
Where any such violation occurs along any public highway the proper
highway authority having jurisdiction of that particular highway is
authorized to take the necessary steps as required by law to enter upon the
property where such violation occurs and backfill or cause to be backfilled
the unlawful excavation or remove or cause to be removed the unlawful spoil
banks, whichever case it may be, or both, in such a manner as will conform
with the foregoing provisions of this Section, and the costs of such work,
together with court costs, may be recovered from such violators in the circuit
court in the county where such violation occurred.
Nothing in this Section shall prohibit the construction and maintenance
of grade separation crossings of any public utility, private corporation or
individuals, or in any way conflict with any other laws governing such
grade separations; nor shall the provisions of this Section in any way
apply to pipe line construction or maintenance where such work is done to
the satisfaction of the highway authorities having jurisdiction over such
public highway; nor to the excavation of earth necessary for the
construction of foundations or basement walls.
