(65 ILCS 5/11-12-6) (from Ch. 24, par. 11-12-6)

Sec. 11-12-6. An official comprehensive plan, or any amendment thereof, or addition thereto, proposed by a plan commission shall be effective in the municipality and contiguous area herein prescribed only after its formal adoption by the corporate authorities. Such plan shall be advisory and in and of itself shall not be construed to regulate or control the use of private property in any way, except as to such part thereof as has been implemented by ordinances duly enacted by the corporate authorities. At any time or times, before or after the adoption of the official comprehensive plan by the corporate authorities, such corporate authorities may designate by ordinance an official map, which map may consist of the whole area included within the official comprehensive plan or one or more separate geographical or functional parts, and may include all or any part of the contiguous unincorporated area within one and one-half miles from the corporate limits of the municipality. Such map or maps shall be made a part of the ordinance, which ordinance shall specifically state standard requirements of the municipality relating to size of streets, alleys, public ways, parks, playgrounds, school sites, other public grounds, and ways for public service facilities; the kind and quantity of materials which shall be used in the construction of streets, and alleys; and the kind and quality of materials for public service facilities as may be consistent with Illinois Commerce Commission or industry standards, and shall contain the standards required for drainage and sanitary sewers and collection and treatment of sewage. The map shall be drawn to scale, shall be reasonably accurate, and shall show north point, section lines and numbers, and streams.

Said official comprehensive plan and the ordinance or ordinances including the official map shall be placed on file with the Municipal Clerk and shall be available at all times during business hours for public inspection. Copies of said plan, all ordinances implementing the same and including the official map, shall be made available to all interested parties upon payment of such sum as the corporate authorities shall determine to be adequate to reimburse the general fund of the municipality for the cost of printing and distributing the same.

(65 ILCS 5/11-12-7) (from Ch. 24, par. 11-12-7)

Sec. 11-12-7. The corporate authorities may initiate plans and maps by requesting the plan commission to prepare an official comprehensive plan and recommend the same, or may originate an official comprehensive plan, or a part thereof, or an amendment thereto, and may refer same or suggested changes in an existing comprehensive plan to the plan commission for its consideration and recommendation thereon. No comprehensive plan or amendment thereto shall be adopted that has not been submitted to the plan commission.

The corporate authorities may adopt parts of a comprehensive plan recommended by a plan commission without adopting the entire comprehensive plan as recommended, or may modify or amend portions of a recommended comprehensive plan without a re-reference of same to the plan commission, and may adopt such comprehensive plan, as modified or amended. Such comprehensive plan, when adopted, shall be the official comprehensive plan, or part thereof, of that municipality.

Upon submission by the corporate authorities of any suggested comprehensive plan, part thereof, or amendment to an existing comprehensive plan to the plan commission for consideration and recommendation, the corporate authorities may require a report thereon from the plan commission with its recommendation within 90 days from the date of such submission, and if the plan commission shall fail to make such report within such 90 days, then the corporate authorities may proceed to consider such comprehensive plan, or part thereof or amendment to an existing comprehensive plan, for adoption, including arranging for and holding of a public hearing thereon in accordance with the provisions hereinafter contained in the same manner as if the plan commission had made its recommendation.

On and after the effective date of this amendatory act of 1961, an official comprehensive plan, or any amendment thereof, shall not be adopted by a municipality until notice and opportunity for public hearing have first been afforded in the manner herein provided. Upon submission of a comprehensive plan by the plan commission, or a proposed amendment to an existing comprehensive plan, the corporate authorities shall schedule a public hearing thereon, either before the plan commission or the corporate authorities. Not less than 15 days' notice of the proposed hearing, and the time and place thereof, shall be given by publication in a newspaper of general circulation in the county or counties in which the municipality and contiguous unincorporated territory are located. The hearing shall be informal, but all persons desiring to be heard in support or opposition to the comprehensive plan or amendment shall be afforded such opportunity, and may submit their statements, orally, in writing, or both. The hearing may be recessed to another date if not concluded, if notice of the time and place thereof is publicly announced at the hearing or is given by newspaper publication not less than 5 days prior to the recessed hearing.

Within 90 days after the conclusion of the hearing, the corporate authorities, after consideration of the recommendation of the plan commission and such information as shall have been derived from the hearing, shall either adopt the comprehensive plan or amendment in whole or in part or reject the entire comprehensive plan or amendment. If adopted, the corporate authorities shall enact the ordinance including a map or maps as hereinbefore provided. In adopting an official comprehensive plan, except as herein otherwise provided, the corporate authorities shall be subject to the same limitations as to subject matter as apply to the plan commission. If at the expiration of such 90 days, the corporate authorities have taken no formal action, the comprehensive plan or amendment thereto may thereafter not be acted upon by the corporate authorities without again complying with the conditions of notice and hearing heretofore provided.

No official map, or amendment or addition thereto, shall be ground for rejection of any plat of subdivision or resubdivision by the corporate authorities, if application for final approval of such subdivision or resubdivision is filed with the corporate authorities 15 days or more prior to the date on which the ordinance approving the official map, or amendment or addition thereto, is adopted.

The comprehensive plan or amendment shall become effective upon the expiration of 10 days after the date of filing notice of the adoption of such comprehensive plan or amendment with the recorder of the county. Whenever used in this Section 11-12-7 the words "plans" or "comprehensive plan" shall be deemed to mean and include, where applicable, an official map or maps.

(65 ILCS 5/11-12-8) (from Ch. 24, par. 11-12-8)

Sec. 11-12-8. Compliance of plat with map; designation of public lands; approval; bond; order; failure to act upon plat. The corporate authorities of the municipality shall determine whether a proposed plat of subdivision or resubdivision complies with the official map. To secure such determination, the person requesting the subdivision or resubdivision shall file four copies of a plat thereof with the clerk of the municipality, and shall furnish therewith four copies of all data necessary to show compliance with all applicable municipal regulations and shall make application for preliminary or final approval of the proposed plat.

Whenever the reasonable requirements provided by the ordinance including the official map shall indicate the necessity for providing for a school site, park site, or other public lands within any proposed subdivision for which approval has been requested, and no such provision has been made therefor, the municipal authority may require that lands be designated for such public purpose before approving such plat. Whenever a final plat of subdivision, or part thereof, has been approved by the corporate authorities as complying with the official map and there is designated therein a school site, park site or other public land, the corporate authorities having jurisdiction of such use, be it a school board, park board or other authority, such authority shall acquire the land so designated by purchase or commence proceedings to acquire such land by condemnation within one year from the date of approval of such plat; and if it does not do so within such period of one year, the land so designated may then be used by the owners thereof in any other manner consistent with the ordinance including the official map and the zoning ordinance of the municipality.

The corporate authorities may by ordinance provide that a plat of subdivision may be submitted initially to the plan commission for preliminary approval. The application for preliminary approval shall show location and width of proposed streets and public ways, shall indicate proposed location of sewers and storm drains, proposed dedication of public grounds, if any, lot sizes, proposed easements for public utilities, and proposed method of sewage and waste disposal, but need not contain specifications for proposed improvements.

The plan Commission shall approve or disapprove the application for preliminary approval within 90 days from the date of the application or the filing by the applicant of the last item of required supporting data, whichever date is later, unless such time is extended by mutual consent. If such plat is disapproved, then within said 90 days the plan commission shall furnish to applicant in writing a statement setting forth the reason for disapproval and specifying with particularity the aspects in which the proposed plat fails to conform to the ordinances including official map. If such plat is approved the corporate authority shall accept or reject said plat within 30 days after its next regular stated meeting following the action of the plan commission. Preliminary approval shall not qualify a plat for recording.

Application for final approval of a plat shall be made not later than one year after preliminary approval has been granted. This application must be supported by such drawings, specifications and bond as may be necessary to demonstrate compliance with all requirements of this statute and such regulations as the corporate authorities may provide by ordinance under authority of this statute. This Section is subject to the provisions of Section 11-39-3 of this Code.

The applicant may elect to have final approval of a geographic part or parts of the plat that received preliminary approval, and may delay application for approval of other parts until a later date or dates beyond one year with the approval of the municipal authorities; provided, all facilities required to serve the part or parts for which final approval is sought have been provided. In such case only such part or parts of the plat as have received final approval shall be recorded.

When a person submitting a plat of subdivision or resubdivision for final approval has supplied all drawings, maps and other documents required by the municipal ordinances to be furnished in support thereof, and if all such material meets all municipal requirements, the corporate authorities shall approve the proposed plat within 60 days from the date of filing the last required document or other paper or within 60 days from the date of filing application for final approval of the plat, whichever date is later. The applicant and the corporate authorities may mutually agree to extend the 60 day period.

Except as provided in Section 3 of the Public Construction Bond Act, the corporate authorities may provide that any person, firm or corporation seeking approval of a subdivision or resubdivision map or plat shall post a good and sufficient cash bond, irrevocable letter of credit, or surety bond with the municipal clerk in a penal sum sufficient to cover the estimate made by the municipal engineer, or other authorized person, of expenditures, including but not limited to reasonable inspection fees to be borne by the applicant, necessary to conform to the requirements established and conditioned upon completion of said requirements in a reasonable time. The corporate authorities may, by ordinance, prescribe the form of the cash bond, irrevocable letter of credit, or surety bond and may require surety to be approved by the corporate authorities; provided, that a municipality may permit the depositing of cash or other security acceptable to the corporate authorities, to complete the improvements required in lieu of a bond if it shall so provide by ordinance; and further provided, that no bond or security shall be required to be filed until the corporate authorities have approved the plat in all other respects and have notified the applicant of such approval. If the corporate authorities require a cash bond, letter of credit, surety, or any other method to cover the costs and expenses and to insure completion of the requirements, the requirements shall be subject to the provisions of Section 11-39-3 of this Code.

If the preliminary or final plat is approved, the municipal clerk shall attach a certified copy of the order or resolution of approval to a copy of the plat. If the proposed plat is disapproved, the order or resolution shall state the reasons for the disapproval, specifying with particularity the aspects in which the proposed plat fails to conform to the official map. A copy of the order or resolution shall be filed in the office of the municipal clerk.

If the corporate authorities fail to act upon the final plat within the time prescribed the applicant may, after giving 5 days written notice to the corporate authorities, file a complaint for summary judgment in the circuit court and upon showing that the corporate authorities have failed to act within the time prescribed the court shall enter an order authorizing the recorder to record the plat as finally submitted without the approval of the corporate authorities. A plat so recorded shall have the same force and effect as though that plat had been approved by the corporate authorities. If the corporate authorities refuse to act upon the final plat within the time prescribed and if their failure to act thereon is wilful, upon such showing and upon proof of damages the municipality shall be liable therefor.

(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 15 consecutive days in the same location at which notices of village board or city council meetings are posted; and

(2) publication on at least one occasion in a newspaper of general circulation within the territory that is subject to the proposed agreement.

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.
