Calgary’s Regulatory Flood Map shows the floodway, flood fringe and overland flood zones. The map is used for land planning purposes, showing the designated flood zones where various development and building regulations apply. The map shows the regulatory flood zones for the Bow River, Elbow River, Nose Creek and West Nose Creek. An annotation file is provided separately as an attachment: (Bylaw Flood Hazard Annotations). This map is the 1:100 flood extent calculated in 1983.

Designated flood elevations (or steplines) associated with these zones are available separately.

For more on the development and building regulations that apply in each designated flood zone, please refer to Calgary’s Land Use Bylaw, Part 3 Division 3. http://www.calgary.ca/PDA/pd/Pages/Calgary-Land-Use-bylaw-1P2007/Calgary-Land-Use-Bylaw-1P2007.aspx

Are you building or renovating?
If you are building or renovating, check the regulatory flood map on this page, and the 1:100 year inundation map (from Flooding in Calgary: Maps http://www.calgary.ca/UEP/Water/Pages/Flood-Info/Calgary-flood-maps/Flood-maps.aspx) to see if your property is in a flood risk zone. Since late 2011, property owners have been advised of both the official designated flood elevation per the Land Use Bylaw (based on this regulatory flood map) and the most up to date recommended flood elevation (based on the updated 1:100 year inundation map) for their specific property.

This dataset makes historical air quality data accessible for various parameters at Calgary monitoring stations. The data is collected by the Calgary Regional Airshed and Alberta Environment and Parks groups. The data is collected via a web service provided by the Alberta Environmental Monitoring, Evaluation & Reporting Agency (AEMERA). AEMERA provides access to historical air quality data at its air quality stations.

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. For further details and definitions, please refer to the attached user guide.
