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.

This digital data set identifies, maps, and classifies ephemeral and intermittent streams in Calgary. This data set is intended for mapping at scales between 1:5,000 and 1:50,000, for the purpose of higher-level analysis and planning, or as a starting point to locate areas of interest to focus more detailed field work and surveys. Please note that the data is not intended to replace or supercede existing requirements during the process of planning, subdivision, and development, including field investigations.
