Senate Bill 873 aims to amend the regulations governing the extraterritorial subdivision authority of incorporated municipalities in Wisconsin. The bill specifies that these municipalities cannot deny approval for land subdivision in their extraterritorial jurisdiction based on certain criteria, including the proposed use of the land, specifications for public improvements, land division design standards, or any agreements related to annexation. This change is intended to streamline the approval process for subdivisions and limit the reasons municipalities can use to deny such approvals.

Additionally, the bill introduces a provision that allows towns to recover reasonable attorney fees if they prevail in legal actions brought to enforce these new regulations. This is designed to provide towns with a financial incentive to ensure compliance with the law and to protect their interests in extraterritorial land regulation disputes. Overall, the bill seeks to clarify and limit the authority of incorporated municipalities in subdivision approvals while providing towns with a mechanism for legal recourse.
