DRAFT Subd. 185 Story. That portion of a building included between the surface of any floor and the surface of the floor next above it, or, if no such floor above, the space between such floor and the ceiling next above it. Subd. 186 Story, half. A space under a sloping roof which has the line of intersection of roof decking and wall face not more than three (3) feet above the top floor level, and in which space not more than two-thirds (2/3) of the floor area is finished for use. A half- story containing independent apartment or living quarters shall be counted as a full story. Subd. 187 Streets. A public or private way, consisting in the case of a private way of a roadway and in the case of a public way of a roadway and a boulevard (the latter of which may contain a sidewalk), used primarily for vehicular traffic, whether designated as a street, avenue, parkway, road, lane, throughway, expressway, highway, place or however otherwise designated. The term "streets" includes the following classifications: A. Collector street. A street which carries traffic from local streets to streets and highways of higher classifications. It provides for both land access service and local traffic movements within residential neighborhoods, commercial areas and industrial areas. B. Cul-de-sac. A street with a circular turn-a-round and only one outlet. C. Local street. A street of limited continuity used primarily for access to the abutting properties and the local needs of a neighborhood. D. Minor arterial. A street system that interconnects with and augment the urban major arterial system and provide service to trips of moderate length at somewhat lower level of travel mobility than major arterials. This system distributes travel to geographical areas smaller than those identified with the higher system. E. Major arterial. Usually a divided highway with four (4) or more lanes and serves the major centers of activity of a metropolitan area, the highest traffic volume corridors, and the longest trip desire. The major arterial carries a high proportion of the total urban area travel on a minimum mileage. Almost all fully and partially controlled access facilities are a part of this class. F. Expressway. A type of major arterial with a controlled access roadway and expressway ramps to provide ingress or egress to other levels of streets. The use of expressway ramps allows the uniform flow of traffic on a major arterial highway without undue delays. Subd. 188 Structural alterations. Any change in the supporting members of a building such as bearing walls, columns, beams or girders, or any substantial changes in the roof and exterior walls. DRAFT: 6/3/2010 Page 24 of 50
