Wis. Stat. § 82.50
2003 Wis. Act 214, which affected this section, contains extensive explanatory notes.
This section vests in a town a certain degree of discretion with respect to complying with minimum standards for town roads. Nothing in the statutes controls the circumstances in which a town may apply for a deviation under sub. (2), which indicates that the application is left to the town's discretion. DSG Evergreen Family Limited Partnership v. Town of Perry, 2020 WI 23, 390 Wis. 2d 533, 939 N.W.2d 564, 17-2352. Sub. (1) does not impose obligations on a town that are susceptible to a declaration of rights, nor does it create a private cause of action by which a plaintiff can recover damages for an alleged failure to construct a proper road. DSG Evergreen Family Limited Partnership v. Town of Perry, 2020 WI 23, 390 Wis. 2d 533, 939 N.W.2d 564, 17-2352.
