Mich. Comp. Laws § 125.75a
Where, pursuant to the development of a project, disposition of acquired lands in accordance with the development plan is hampered by reason of the size or character of the lots or tracts of land within the development area, and where diversification of ownership within the development area prohibits redesign by means of a proprietor's plat, the municipality, by action of its governing body, may authorize a plat or replat of the area or any part thereof to be made by a registered civil engineer or a registered land surveyor.
The plat shall be prepared, approved and recorded as provided in Act No. 172 of the Public Acts of 1929, as amended, being sections 560.1 to 560.80 of the Compiled Laws of 1948, except that the certificate of the county and city treasurer relating to tax titles and tax liens shall not be required, and in lieu of the signature of the proprietor of the land the dedication shall be signed by the director of urban renewal or by the administrative officer of the municipality and shall refer to this act as the authority for certification. There shall be set forth in the title of the plat the words "urban renewal plat" or "urban renewal replat". Unplatted and previously platted lands may be included in the same plat, and such plat shall supersede all previously recorded plats in the area covered by the urban renewal plat or urban renewal replat.
All lands within the development area, whether publicly or privately owned, may be included in the urban renewal plat or urban renewal replat, and all land so platted shall be divided into lots and be numbered in accordance with the development plan, except that no lot shall include property in both public and private ownership, nor in 2 or more individual private ownerships, unless such division is of a lot in a recorded subdivision which was so divided prior to the making of the urban renewal plat or urban renewal replat.
The plat or replat shall state in the dedication that necessary rights to all highways, streets, alleys and public places, including parks, green belts and buffer strips, have been acquired by the municipality by purchase, dedication, condemnation or adverse possession for public use, prior to the making of the urban renewal plat or urban renewal replat.
All easements retained by the municipality for the development of the project shall be designated on the urban renewal plat or urban renewal replat and become a part thereof.
An urban renewal plat or urban renewal replat shall conform in all respects to the urban renewal project plan for the area in which said plat or replat may be located. An urban renewal plat or urban renewal replat, when approved by the governing body where the lands are located, shall not be rejected for the reason that any lot shown thereon fails to meet minimum requirements as to width as prescribed by Act No. 172 of the Public Acts of 1929, as amended.
An urban renewal plat or urban renewal replat, when recorded and filed, shall be treated in respect to assessment, return of taxes and sale of lands for delinquent taxes and for all other purposes, the same as if made by the proprietor under the general provisions of Act No. 172 of the Public Acts of 1929, as amended.
