(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 1/500 or a 0.2% 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 Potential failure of flood protection barrier - Low lying areas that could be flooded if an existing permanent flood protection barrier were to fail.

The flood areas shown were mapped in 2015 jointly by Alberta Environment and Parks and the City of Calgary, using the best available hydrologic and hydraulic data and models. As such, the flooding shown reflects 2015 conditions, hydrology and topography. The effects of mitigation measures (changes to reservoirs/dams or barriers) built since 2015 are not included. 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.

This dataset identifies the roads in the City of Calgary where temporary signage is prohibited under the Temporary Signs on Highway Bylaw 29M97. The identified roads are effective Jan 1, 2024.
*Notice of pilot to run from May 1st to October 31st, 2024. There is a data subset provided on the map that shows previously prohibited roadways that we will allow signage to be installed at for the duration of the pilot.

Data were compiled from 6 hour intersection counts, 24 hour automatic counts and permanent count stations from 2011 to 2016. Segment truck percentages are based on adjacent intersection counts. In some cases, when no current data was available, older data was used. The percent truck map is intended to be a general representation of percent trucks across the city in a given year. Percentages shown are based on a variety of sources and may reflect prevailing conditions including detours and operating conditions in place during the year

Final results of the 2021 General Election. Senate results by ward and voting station.

Ward-level tabulations of annual census counts of residents, dwellings, and dwelling occupancy, categorized by dwelling structure type. Ward boundaries can change over time. These results are based on the ward boundaries at the time of data collection in each year.

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 1/35 or a 2.9% 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.

Interprovincial and intraprovincial migrants, by census metropolitan area and census agglomeration of origin and destination, 2021 boundaries.

The data in this map are 2-way 16-hour (6:00-22:00) volumes collected on a single weekday in 2016, factored to represent the average September/October volume. Factors were calculated based on 13 automated count stations.

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.
