1 | AN ACT concerning local government.
| |||||||||||||||||||
2 | Be it enacted by the People of the State of Illinois,
| |||||||||||||||||||
3 | represented in the General Assembly:
| |||||||||||||||||||
4 | Section 5. The Illinois Municipal Code is amended by | |||||||||||||||||||
5 | changing Section 11-12-9 as follows:
| |||||||||||||||||||
6 | (65 ILCS 5/11-12-9) (from Ch. 24, par. 11-12-9)
| |||||||||||||||||||
7 | Sec. 11-12-9. If unincorporated territory is within one and | |||||||||||||||||||
8 | one-half miles
of the boundaries of two or more corporate | |||||||||||||||||||
9 | authorities that have adopted
official plans, the corporate | |||||||||||||||||||
10 | authorities involved may agree upon a line
which shall mark the | |||||||||||||||||||
11 | boundaries of the jurisdiction of each of the
corporate | |||||||||||||||||||
12 | authorities who have adopted such agreement. On and after
| |||||||||||||||||||
13 | September 24, 1987, such agreement may provide that one or more | |||||||||||||||||||
14 | of the
municipalities shall not annex territory which lies | |||||||||||||||||||
15 | within the jurisdiction
of any other municipality, as | |||||||||||||||||||
16 | established by such line. In the absence of
such a boundary | |||||||||||||||||||
17 | line agreement, nothing in this paragraph shall be
construed as | |||||||||||||||||||
18 | a limitation on the power of any municipality to annex
| |||||||||||||||||||
19 | territory. In arriving at an agreement for a jurisdictional | |||||||||||||||||||
20 | boundary line,
the corporate authorities concerned shall give | |||||||||||||||||||
21 | consideration to the natural
flow of storm water drainage, and, | |||||||||||||||||||
22 | when practical, shall include all of any
single tract having | |||||||||||||||||||
23 | common ownership within the jurisdiction of one
corporate |
| |||||||
| |||||||
1 | authority. Such agreement shall not become effective until | ||||||
2 | copies
thereof, certified as to adoption by the municipal | ||||||
3 | clerks of the respective
municipalities, have been filed in the | ||||||
4 | Recorder's Office and made available
in the office of the | ||||||
5 | municipal clerk of each agreeing municipality.
| ||||||
6 | Any agreement for a jurisdictional boundary line shall be | ||||||
7 | valid for such
term of years as may be stated therein, but not | ||||||
8 | to exceed 20 years, and if
no term is stated, shall be valid | ||||||
9 | for a term of 20 years. The term of such
agreement may be | ||||||
10 | extended, renewed or revised at the end of the initial or
| ||||||
11 | extended term thereof by further agreement of the | ||||||
12 | municipalities.
| ||||||
13 | For territory located within 5 miles of the Midewin | ||||||
14 | National Tallgrass Prairie, if one or more municipalities have | ||||||
15 | agreed upon a jurisdictional boundary line and an application | ||||||
16 | for annexation, zoning change, or a similar development request | ||||||
17 | has been made by a third party to one of the municipalities | ||||||
18 | that is a party to such an agreement or agreements, the | ||||||
19 | agreement or agreements between each of the municipalities are | ||||||
20 | automatically extended for a period of 20 years from the date | ||||||
21 | the application or development request is filed if: (1) as of | ||||||
22 | the date the application or development request is filed, a | ||||||
23 | boundary agreement expired within the last calendar year or | ||||||
24 | there is less than 10 years remaining on a boundary agreement | ||||||
25 | or agreements between municipalities; (2) the proposed | ||||||
26 | development is in excess of 500 acres; and (3) the proposed |
| |||||||
| |||||||
1 | development is located within 2 miles of any jurisdictional | ||||||
2 | boundary line set forth in a boundary agreement or agreements | ||||||
3 | or the proposed development would require annexing land that is | ||||||
4 | designated to another municipality under an existing boundary | ||||||
5 | agreement. | ||||||
6 | In the absence of such agreement, the jurisdiction of any | ||||||
7 | one of the
corporate authorities shall extend to a median line | ||||||
8 | equidistant from its
boundary and the boundary of the other | ||||||
9 | corporate authority nearest to the
boundary of the first | ||||||
10 | corporate authority at any given point on the line.
| ||||||
11 | On and after January 1, 2006, no corporate authority may | ||||||
12 | enter into an agreement pursuant to this Section unless, not | ||||||
13 | less than 30 days and not more than 120 days prior to formal | ||||||
14 | approval thereof by the corporate authority, it shall have | ||||||
15 | first provided public notice of the proposed boundary agreement | ||||||
16 | by both of the following: | ||||||
17 | (1) the posting of a public notice for not less than 15 | ||||||
18 | consecutive days in the same location at which notices of | ||||||
19 | village board or city council meetings are posted; and | ||||||
20 | (2) publication on at least one occasion in a newspaper | ||||||
21 | of general circulation within the territory that is subject | ||||||
22 | to the proposed agreement. | ||||||
23 | The validity of a boundary agreement may not be legally | ||||||
24 | challenged on the grounds that the notice as required by this | ||||||
25 | Section was not properly given unless the challenge is | ||||||
26 | initiated within 12 months after the formal approval of the |
| |||||||
| |||||||
1 | boundary agreement.
| ||||||
2 | An agreement that addresses jurisdictional boundary lines | ||||||
3 | shall be entirely unenforceable for any party thereto that | ||||||
4 | subsequently enters into another agreement that addresses | ||||||
5 | jurisdictional boundary lines that is in conflict with any of | ||||||
6 | the terms of the first agreement without the consent of all | ||||||
7 | parties to the first agreement.
For purposes of this Section, | ||||||
8 | it shall not be considered a "conflict" when a municipality | ||||||
9 | that is a party to a jurisdictional boundary line agreement | ||||||
10 | cedes property within its own jurisdiction to another | ||||||
11 | municipality not a party to the same jurisdictional boundary | ||||||
12 | line agreement. | ||||||
13 | This amendatory Act of 1990 is declarative of the existing | ||||||
14 | law and
shall not be construed to modify or amend existing | ||||||
15 | boundary line
agreements, nor shall it be construed to create | ||||||
16 | powers of a municipality not
already in existence.
| ||||||
17 | Except for those provisions to take effect prospectively, | ||||||
18 | this amendatory Act of the 94th General Assembly is declarative | ||||||
19 | of existing law and shall not be construed to modify or amend | ||||||
20 | existing boundary line agreements entered into on or before the | ||||||
21 | effective date of this amendatory Act, nor shall it be | ||||||
22 | construed to create powers of a municipality not already in | ||||||
23 | existence on the effective date of this amendatory Act. | ||||||
24 | The changes made by this amendatory Act of the 101st | ||||||
25 | General Assembly modify existing boundary line agreements and | ||||||
26 | apply retroactively to applications for annexation, zoning |
| |||||||
| |||||||
1 | change, or a similar development request made on or after | ||||||
2 | January 1, 2020. | ||||||

| ||||||
4 | Section 99. Effective date. This Act takes effect upon | ||||||
5 | becoming law. |
