The Street Types (street_typ) are developed, identified, and mapped by the City Planning Commission and reference street Center lines. The Street Types take into account, traditional levels of service for automobiles, pedestrian activity and land use. Upwards of thirty columns (from street_typ to stormwater) are populated according to the Complete Streets Handbook, as managed by the Streets Department and the Mayors Office of Transportation and utilities. The Pedestrian and Bicycle Plan, as well as the Complete Streets Handbook both serve as the referenes for this shapefile.
