The plat shall include owner's certificates with a statement of dedication properly conveying all lands dedicated for such public uses, including streets, utility easements, parks, open space and recreation purposes, or other public uses, as well as all restrictions as may be applied to the subdivision. In the event that the restrictions are lengthy, the owner may elect to record them as a separate instrument, noting in the certificate the proper recorder's number, and that the restrictions as recorded run concurrently with the plat, in the same manner as if included therein.
(i) Building lines. The plat shall show building lines conforming to the requirements of the applicable zoning code for front yards.

(2) After receiving a report from the Administrator, the Planning and Zoning Commission shall consider the proposed preliminary plat based on the requirements of this chapter and shall, within 90 days after its consideration thereof, make a recommendation to the City Council as to whether approval of the preliminary plat should be granted, denied or granted with modifications or conditions.
(3) If the City Council approves the preliminary plat, it shall be returned to the subdivider for compliance with final plat approval requirements. Unless otherwise agreed to by the City Council and the subdivider, the City Council shall act on the preliminary plat at its next regularly scheduled meeting within 30 days following the recommendation of the Planning and Zoning Commission.
(4) If the preliminary plat is denied approval by the City Council, the Council's objections to it shall be noted, and the subdivider may modify the preliminary plat and resubmit it to the Administrator.
(5) An approved preliminary plat shall be valid for one year, during which time the subdivider shall obtain City Council approval of a final plat. Upon written application, extensions of not to exceed one year for each extension authorized may be granted by the City Council.
(B) Final plat.
(1) Filing of final plat. The subdivider shall file the final plat, including the required number of copies thereof, with the Administrator. Such plat shall substantially conform with the preliminary plat, including any modifications thereto required by the approval thereof by the City Council.
(2) Action of the City Council. Upon receipt of the final plat, the Administrator and City Engineer shall immediately review the plat, and if the plat is in acceptable form and in conformance with the preliminary plat, the approval thereof by the City Council, and the requirements established in this chapter, the Administrator shall forward such plat to the Planning and Zoning Commission. The Planning and Zoning Commission shall examine the final plat and shall promptly recommend to the City Council that approval of the plat be granted or denied, or granted with modifications or conditions. The City Council shall approve or disapprove said final plat within 60 days from the date of filing of the last required document or within 60 days from the date of the filing of the application for final approval of the plat, whichever date is later, unless the time is extended by agreement with the subdivider. Failure of the City Council to act within such time shall be deemed a denial. After the final plat is approved by the City Council, the City Clerk shall cause a certified copy of the resolution or ordinance approving such plat to be attached to the plat and returned to the subdivider. A copy of the resolution or ordinance and plat shall be transmitted to the Administrator, and a copy shall also be promptly recorded in the office of the DuPage County Recorder of Deeds.
(C) Street vacations. As part of any subdivision, a street, or any part thereof, may be vacated by ordinance of the City Council pursuant to the authority and procedures as set forth in ILCS Ch. 65, Act 5, § 11-91-1.
