Mich. Comp. Laws § 41.275
The commissioners shall hear objections to the proposed improvement at the time and place to be fixed by them either at the office of the commissioners or at some suitable place within the township in which the proposed special assessment district is located: Provided, That the holding of such hearing may be enforced by mandamus in case the commissioners shall fail to hold the hearing within 60 days after the filing of the petition required under section 1 of this act. At this hearing all parties or persons interested shall be given an opportunity to present their objections, if any, to the proposed improvement. Notice of this hearing shall be given by the commissioners by causing a notice thereof to be published at least once in each week for 2 weeks in succession in some newspaper of general circulation in such district, and by posting 5 notices within the limits of such district, in public and conspicuous places therein. Such posting shall be done and at least 1 publication in the newspaper shall be made not less than 10 days prior to such hearing. Such notice shall set forth a description of the boundaries of the proposed special assessment district or the several parcels of land proposed to be assessed on account of such improvement and the time and place of hearing. At this hearing the commissioners shall make any changes in the specifications deemed advisable without further notice or hearing, provided such changes do not increase the estimate more than 10 per cent. If they do increase the estimate more than 10 per cent, then a new hearing shall be had and notice thereof given as in the first instance. At such hearing, the commissioners may alter the boundaries of the proposed assessment district: Provided, however, That if said district is enlarged or otherwise altered so as to embrace additional lands, hearing thereon after due notice shall be had as hereinbefore provided.
