(1) Subdivision plat names shall be subject to the approval of the county surveyor or, in the case where there is no county surveyor, the county assessor. No tentative subdivision plan or subdivision plat of a subdivision shall be approved which bears a name similar to or pronounced the same as the name of any other subdivision in the same county, unless the land platted is contiguous to and platted by the same party that platted the subdivision bearing that name or unless the party files and records the consent of the party that platted the contiguous subdivision bearing that name. All subdivision plats must continue the lot numbers and, if used, the block numbers of the subdivision plat of the same name last filed. On or after January 1, 1992, any subdivision submitted for final approval shall not use block numbers or letters unless such subdivision is a continued phase of a previously recorded subdivision, bearing the same name, that has previously used block numbers or letters.
