Identifies variable width biophysical riparian areas along major rivers and streams in Calgary, as of 2012. Four separate riparian zones are delineated: Inner Riparian, Middle Riparian, Outer Riparian, and Potential Outermost Riparian. Boundaries are based on city-wide models driven by distance from the river/stream, slope profiles from digital elevation models, and field work calibration based on sampling of riparian plant community locations. Note that the methods identify both developed and undeveloped riparian areas.

Depicts basic components of The City of Calgary's 2007 Environmental Reserve (ER) Setback Guideline policy, including the base setback based on stream order, and the additional setback modifier based on slope. This can be used as a starting point to scope out riparian-associated ER requirements for planned future developments. It can also be used within existing built areas of the city to highlight past lost ER opportunities.
