MI HB4831

Streamlines the process for adding or removing counties from existing drainage districts by clarifying that counties may be added to any drainage district or removed from intercounty drainage districts under specified procedures

Requires petitions for adding or removing counties to be signed by at least 5 freeholders (or 50% if fewer than 5) whose lands will be assessed, or by municipalities authorized by their governing bodies

Mandates certified mail notice to the Department of Agriculture and Rural Development and affected county drain commissioners, with public notice requirements including first-class mailing to landowners and newspaper publication at least 10 days before meetings

Allows drainage boards to determine by majority vote whether adding or removing counties is necessary for public health, convenience, or welfare, with the resulting order required to name the drain, describe boundaries, and designate revised board membership for intercounty districts

Provides appeal rights for drain commissioners to challenge county apportionments or additions/removals through arbitration, and allows aggrieved landowners or municipalities to challenge boundary revision decisions in circuit court within 10 days
