Description

Step lines define the regulatory flood elevation levels within the floodway/flood fringe. The official designated flood elevation indicated by the text applies within the section of the river between the two lines (one upstream and one downstream) where the number is written. An annotation file with the elevations is provided separately as an attachment (see "About" menu).
These flood elevations reference Calgary’s Regulatory Flood Map (available separately). The 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.
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.
