A. Correcting Filed Final Plats: Correction of drafting or surveying errors that, in the city council's opinion, will not materially alter the plat, its land division, or the improvements to less than the standards contained herein, may be made by the submission of a corrected final plat for the city council's approval. The plat must be entitled "Corrected Plat of the (name of subdivision) Subdivision" and the reason for the correction must be stated on the face of the plat.
B. Amending Filed Final Plats: Changes that materially alter the final plat or any portion thereof or its land divisions or improvements must be made by the filing of an amended plat showing all alterations. Within a platted subdivision, any division of lots which result in:
1. Increase in the number of lots;
2. Redesigns or rearranges six (6) or more lots; or
3. Results in significant material changes.
If the amendments to the plat result in significant material changes, the amended plat must be subject to procedural requirements for major and minor subdivisions as outlined in this chapter. Amended plats must be subject to all standards contained in these regulations and an amended plat must be filed with the county clerk and recorder.
The final amended plat submitted for approval must comply with the final plat requirements of this chapter with the exception that the title must include the word "amended" ("Amended Plat of the [name] Subdivision" or "[name] Subdivision, Amended").
C. Amendment Exemption: The relocation of common boundaries and the aggregation of lots within platted subdivision where five (5) or fewer of the original lots are affected are exempt from approval procedures as a subdivision. In such case, an amended plat must be prepared following the requirements of these regulations, except that in place of the city council's approval, the landowner certifies that the approval of the city council is not required pursuant to Montana Code Annotated section 76-3-207(1), as amended.
