Storm Utilities

Sample of Storm Utilities MapStorm Utility Section Maps show the major components of the Storm Sewer System infrastructure within The City of Calgary. The maps are divided into individual legal sections because of the size of the datasets involved.

The major datasets shown on the maps include storm mains, manholes, culverts, outfalls, catch basins, and commercial services/private areas. The mains shown are located by line assignments referenced from property lines, easements, and utility rights-of-way. The property line information is not included in the maps but can be obtained by purchasing either the Legal Survey Fabric (LSF) or Ownership Parcel Fabric (OPF) map with the corresponding section number.
