(Ordinance 83-150-3, § 3(C)(1), adopted 7/26/1983)
(a) 
If desired by the subdivider and approved by the planning commission, the final plat may constitute only that portion of the approved preliminary plat which he proposes to record and develop. However, such portion shall conform to all the requirements of this article and the portion or portions of the subdivision for which the final plat is drawn and submitted for approval shall be in successive order of development as exhibited on the previously approved preliminary master plat. All street, water, sewer and storm drainage facilities shown on the final plat shall be constructed in their entirety or acceptable surety provided before acceptance by the city and before such final plat is recorded in the office of the county clerk.
(b) 
As soon as practical after the subdivider is notified of the approval of the preliminary plat, his engineer shall submit to the planning commission at an official meeting the final plat of the subdivision or portion thereof.
(c) 
No final plat shall be considered unless a preliminary plat has first been submitted and approved. However, if a preliminary plat has been duly approved and the subdivider wishes to increase the size of the lots by combining two or more lots or by combining one lot with a portion of the adjacent lot in such manner that no portion of a lot remains smaller than the original lots, no additional preliminary plat will be necessary.
(d) 
A final plat of an approved preliminary plat or a portion thereof shall be submitted to the planning commission within six months of the date of approval of the preliminary plat, otherwise the approval of the planning commission shall become null and void, unless an extension of time is applied for and granted by the city council.
(e) 
When the final plat is filed with the planning commission for approval, it shall be accompanied by a filing fee as on file in the city secretary's office.
(f) 
Within 30 days after the final plat is formally filed, the planning commission shall approve or disapprove such plat. If the final plat is disapproved, the planning commission shall inform the subdivider in writing of the reasons at the time such action is taken.
(g) 
After the plat has been approved and the subdivider has filed the required security hereinafter provided, the subdivider shall cause the final plat to be recorded with the county clerk.
(h) 
No building permits will be issued by the city until four copies of the recorded final plat have been furnished to the city secretary.
(i) 
Before the planning commission shall give approval to a final plat, the planning commission must have on file a letter addressed to the city from the city engineer stating that all platting and engineering requirements of this article have been met by the developer, including any variances granted by the planning commission or the city council. The city engineer shall file such letter within ten days following receipt of a copy of such final plat in the engineer's office.
(j) 
A final plat which has been approved by the planning commission must be filed with the county clerk within 12 months following the date of approval. If a final plat, for which approval has been given, has not been filed for record in the office of the county clerk on or before the expiration of one year from date of approval, the city may withdraw such approval by sending notice of such withdrawal to the developer by certified mail, return receipt requested, to the address of the developer as shown on the application for plat approval submitted to the planning commission. Copies of such notice of withdrawal shall also be sent to any lienholders shown on the subdivision file or any surety who has posted any guaranty of performance bond for the benefit of the developer.
(k) 
No building permits shall be issued for any construction within, nor utilities extended to, a subdivision from which approval has been withdrawn. Nor shall the city be required to grant permits within the subdivision until the developer resubmits the subdivision plat to the planning commission for approval. Any plat so resubmitted must conform to the city's subdivision regulations in effect on the date of resubmission.
(l) 
The city council expressly reserves to itself the final approval of all subdivisions prior to filing for record in the office of the county clerk.
