Inventory and Assessment of Denver, Colorado: Curb and Gutters

The City and County of Denver (CCD) and the University of Colorado Denver have been involved in cooperative research since 1997. Although a variety of projects have been completed, the main deliverable has been a comprehensive geographic information system database containing both major and minor infrastructure. Major infrastructure includes assets such as bridges and streets, while minor infrastructure includes alleys and street subsystems, such as curbs, gutters, inlets, sidewalks, driveways, cross-pans, and handicap ramps. This paper presents the equipment, methodology, results, and applications based on the inventory and analysis of the CCD’s concrete curb and gutter infrastructure. In summary, approximately 3,300 lineal mi (5,280 km) of curb and gutter were inventoried and inspected over a period of three years at a cost to the CCD of approximately $100 per mile.
