An extent of land covered by, intermittent and permanent, water bodies and watercourses. This includes both parcel bounding and non-parcel bounding occurrences. Includes the natural watercourses as follows: Bow River Elbow River Nose Creek West Nose Creek Fish Creek. This is a generalized version of the data set and is intended for cartographic purposes and faster drawing time.

(Note: Updated inundation maps for 1:2 to 1:1000 floods are available from Alberta Environment and Parks (2020). The new draft maps can be viewed here: https://floods.alberta.ca/?app_code=FI&mapType=Draft)
These inundation maps show whether a property is at risk for various sized river floods. The size of flood shown on this map has a 1/10 or a 10% chance of occurring in any year.
The three distinct types of inundation shown on the maps are:
o Inundation - Area flooded overland due to riverbank overtopping.
o Isolated - Low lying areas that will not be wet from riverbank overtopping, but may experience groundwater seepage or stormwater backup.
o Protected - Area protected by a permanent flood barrier.
The flood areas shown are based on Alberta Environment and Parks most recent (2020) inundation maps. There is uncertainty inherent in predicting the effects of flood events, and this uncertainty increases for floods with less than a 1% chance of occurrence in any year. Any use of this data must recognizing the uncertainty with regards to the exact location and extent of flooding.

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 (see "About" menu").

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.

The flood extents line was manually delineated from an aerial photo taken on June 22, 2013, and does not represent the peak or maximum flood extents during the June 2013 flood event. This aerial photo was taken somewhat after the flood peak had passed. Actual peak flood extents may have been greater than shown.

The approximate flows at the time the aerial photo was taken:
-Bow River upstream of where the Elbow River joins it: 1575 m3/s at time of aerial photo (1840 m3/s at 2013 flood peak flow)
-Elbow River downstream of Glenmore Dam: 550m3/s at time of aerial photo (700 m3/s at 2013 flood peak flow).

This dataset is collected by the Calgary Region Airshed Zone (CRAZ) and submitted to Alberta Environment and Parks (AEP). AEP provides access to air quality data at its air quality stations. The near real-time data has not had quality assurance processes completed for it. Please use at your own discretion.

Tree Canopy contains polygons outlining the extent of tree cover for all land within the City of Calgary. The tree canopy was derived by Remote Sensing software using City of Calgary Orthophotos and Lidar. The resulting data was then quality controlled and edited using various photogrammetric and processing tools.

Results are displayed over time. Users can filter for site and parameter. Values below the reporting limit (< RL) are represented in red.
