Abstract This linear feature class is part of the Bureau of Transportation’s sidewalk system (the entire system consists of sidewalk, corners and curbs). Curbs not only provide the edge for the pedestrian network but they also channel water to the drainage system which helps preserve the street pavement. This dataset contains five types of curbs under the attribute CurbType. These first three types are actual curbs, most commonly constructed of concrete: Blockface (3110), Corner (3120) and Island (3130). The dataset also includes Shoulders (3140), which graphically indicate the edge of pavement where there is no structural curb, and Parking Blocks (3150), which are generally short lengths of flexible curb used as an extra safety barrier, such as in bicycle corral configurations. Attribution includes width, style and drainage information. 
Purpose To provide location and configuration information for the curb. Locations are not mapped with high precision but every effort is made to continually improve accuracy.
