(65 ILCS 5/11-12-9) (from Ch. 24, par. 11-12-9)
Sec. 11-12-9. If unincorporated territory is within one and one-half miles
of the boundaries of two or more corporate authorities that have adopted
official plans, the corporate authorities involved may agree upon a line
which shall mark the boundaries of the jurisdiction of each of the
corporate authorities who have adopted such agreement. On and after
September 24, 1987, such agreement may provide that one or more of the
municipalities shall not annex territory which lies within the jurisdiction
of any other municipality, as established by such line. In the absence of
such a boundary line agreement, nothing in this paragraph shall be
construed as a limitation on the power of any municipality to annex
territory. In arriving at an agreement for a jurisdictional boundary line,
the corporate authorities concerned shall give consideration to the natural
flow of storm water drainage, and, when practical, shall include all of any
single tract having common ownership within the jurisdiction of one
corporate authority. Such agreement shall not become effective until copies
thereof, certified as to adoption by the municipal clerks of the respective
municipalities, have been filed in the Recorder's Office and made available
in the office of the municipal clerk of each agreeing municipality.
Any agreement for a jurisdictional boundary line shall be valid for such
term of years as may be stated therein, but not to exceed 20 years, and if
no term is stated, shall be valid for a term of 20 years. The term of such
agreement may be extended, renewed or revised at the end of the initial or
extended term thereof by further agreement of the municipalities.
In the absence of such agreement, the jurisdiction of any one of the
corporate authorities shall extend to a median line equidistant from its
boundary and the boundary of the other corporate authority nearest to the
boundary of the first corporate authority at any given point on the line.
On and after January 1, 2006, no corporate authority may enter into an agreement pursuant to this Section unless, not less than 30 days and not more than 120 days prior to formal approval thereof by the corporate authority, it shall have first provided public notice of the proposed boundary agreement by both of the following: (1) the posting of a public notice for not less than | ||
| ||
(2) publication on at least one occasion in a | ||
| ||
The validity of a boundary agreement may not be legally challenged on the grounds that the notice as required by this Section was not properly given unless the challenge is initiated within 12 months after the formal approval of the boundary agreement.
An agreement that addresses jurisdictional boundary lines shall be entirely unenforceable for any party thereto that subsequently enters into another agreement that addresses jurisdictional boundary lines that is in conflict with any of the terms of the first agreement without the consent of all parties to the first agreement.
For purposes of this Section, it shall not be considered a "conflict" when a municipality that is a party to a jurisdictional boundary line agreement cedes property within its own jurisdiction to another municipality not a party to the same jurisdictional boundary line agreement. This amendatory Act of 1990 is declarative of the existing law and
shall not be construed to modify or amend existing boundary line
agreements, nor shall it be construed to create powers of a municipality not
already in existence.
Except for those provisions to take effect prospectively, this amendatory Act of the 94th General Assembly is declarative of existing law and shall not be construed to modify or amend existing boundary line agreements entered into on or before the effective date of this amendatory Act, nor shall it be construed to create powers of a municipality not already in existence on the effective date of this amendatory Act.

If a municipality has adopted an official plan or map
pursuant to the authority granted by this Division 12, the territory
subject to that plan shall be exempt from the application of any less
restrictive rules or regulations adopted by a County Board under the
provisions of Section 5-1042 of the Counties Code.

Sec. 11-12-12.
No map or plat of any subdivision presented for record
affecting land (1) within the corporate limits of any municipality which
has heretofore adopted, or shall hereafter adopt an ordinance including an
official map in the manner prescribed in this Division 12, or (2) within
contiguous territory which is not more than 1 1/2 miles beyond
the corporate limits of an adopting municipality, shall be entitled to
record or shall be valid unless the subdivision shown thereon provides for
streets, alleys, public ways, ways for public service facilities, storm and
flood water run-off channels and basins, and public grounds, in conformity
with the applicable requirements of the ordinances including the official
map; provided, that a certificate of approval by the corporate authorities,
certified by the clerk of the municipality in whose jurisdiction the land
is located, or a certified copy of an order of the circuit court directing
the recording as provided in Section 11-12-8, shall be sufficient evidence
of compliance with this section upon which the recorder may accept
the plat for recording.
The provisions of this Section do not apply to any plat for consolidation
of 2 or more contiguous parcels, located within any territory
that is outside of the corporate limits of a municipality but within a county
that has adopted a subdivision ordinance and that has a population of more than
250,000, into a smaller
number of
parcels if the sole purpose of the consolidation
is to bring a non-conforming parcel into conformance with local
zoning requirements.
The exemption created by this amendatory Act of the 92nd General Assembly
does not apply to a plat for consolidation for an area in excess of 10 acres
or to any consolidation that results in a plat of more than 10 individual lots
following the consolidation. If the county receives a request to approve a plat
for consolidation pursuant to this Section, the county must notify
all municipalities located within 1 1/2 miles of the subject property within 10
days after receiving the request.

assist in the administration and enforcement of zoning and building codes or
ordinances throughout the region.

by such intergovernmental agreement may provide for the joint plan commission
