Alternative roadway design strategies fall into two general categories: 1. Local street design, including ?connectivity? and ?skinny street? ordinances, and 2. Context-sensitive design for freeways and other large-scale projects. Portland, OR, for example, has adopted an ordinance that reduces the maximum allowable block length in new developments to 300(?) feet and the required width for residential streets to 28 feet and sidewalk width of at least 5 feet and landscaped pedestrian buffer strips that include street trees. The Federal Highway Administration has promoted the concept of flexibility in highway design, enabling state departments of transportation to design new and rebuilt facilities that are sensitive to the local context. Context-sensitive design includes provisions for local traffic, including non-motorized modes, and attention to the aesthetic qualities of facilities. Source/Reference: Portland Metro, 2001.
