A library of construction drawings for projects that have been built in the city has many uses; whether there is a new project being built "next door," or the old one needs some maintenance, there are numerous practical benefits. After a project is constructed, drawings are submitted to the city by the design engineer with any changes that occurred during construction. These "as-built" drawings are the ones maintained on file.
Quarter-section maps are available for the entire City. The quarter-section maps display the major utility lines throughout the city. These are both maintained in a digital PDF and GIS Shapefile format.
The city does not maintain or retain files for utilities located on residential private property.
To view these materials in person:
The Mapping Division is located within the Development Services Department at the former Bead Museum, 5754 W Glenn Dr. The main entrance to the building faces the small courtyard to the east. We are available Monday - Friday, 8 am to 5pm.
