Milwaukee & Suburban Transport Corp. 56 Wis. 2d 504, 202 N.W.2d 415 (1972). The defendant property owners' failure to remove snow and ice from sidewalks in violation of a municipal ordinance did not constitute negligence per se. Hagerty v. Village of Bruce, 82 Wis. 2d 208, 262 N.W.2d 102 (1978). A city, exercising its police power, can impose a special tax on properties for the cost of installing a sidewalk on an adjacent city right-of-way without showing that the properties would be benefited.
