Main breaks happen year-round. There are many contributing factors including: Pipe Age, Pipe Material and Soil Conditions, and Temperature. See this link for more information: http://www.calgary.ca/UEP/Water/Pages/construction-projects/Water-main-repairs-and-maintenance/water-outages.aspx

Energy consumption at City facilities. This raw data is subject to periodic adjustments and modifications.

This is a measure of the rain accumulated at various rain gauges throughout the City during the rain season, which typically runs from May 1- Sep 30. Readings are taken at 5 minute intervals, and updated daily.
This data is QA/QC'd on an annual basis at the end of the calendar year at which time some adjustments may be made to the data. Users should keep in mind that data viewed before March 31 of the following year should be considered in a ‘raw’ state and may be subject to change

Raster data consisting of processed LANDSAT imagery for the specific dates available in the Urban Heat App. The three different datasets in each year represent Land Surface Temperature (LST, raster values in decimal degrees), NDVI (vegetation index) and Impervious (built-up or impervious index).

The rasters are all contained within a single zip file, currently 90 MB in size. The package will be updated whenever new data is processed and added to the Urban Heat app, which is expected to be annually.
The CRS is: EPSG: 32612 WGS 84/UTM 12N

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: (Bylaw Flood Hazard Annotations).
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.

(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 1/1000 or a 0.1% 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.

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 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.

Using data collected between 2012 and 2017, The City has created this solar potential dataset of all buildings within city limits. The data shows varying degrees of a roof’s solar exposure, on an annual basis, in generalized optimal conditions. The data model used to generate the map takes into account the shape of the terrain and the relative position of building rooftops and structures, existing infrastructure, and tree canopies. It doesn’t take into account weather conditions, such as cloudy days and precipitation that limit a roof’s direct solar exposure. It also does not reflect any new adjacent structures built after 2012 that may obstruct another building’s solar exposure.

The Yield levels are measured as kWh\m2\day. Yield values are interpreted as: Low Yield (0 - 0.87); Low Moderate Yield (0.87 - 1.74); High Moderate Yield (1.74 - 2.61); High Yield (2.61 - 3.48)

The compressed file for download is 4.25 GB. The uncompressed files are 4.5 GB. Data is arranged in Townships, with 18 GeoTiff image files in total.

The Solar map data is intended for information purposes only and as a preliminary solar opportunity assessment tool. It is not intended to be used as a decision making source of information for solar panel installations.

The impervious surface layer contains polygon features generated from Digital Aerial Survey mapping line work. The layer features represent the various impervious surface types found within The City of Calgary. These features are classified by surface type and description based on the classification and specifications used in the Digital Aerial Survey Program. Additional higher level general surface type classification has been applied to each impervious surface layer feature. To learn more about other DAS products available, visit Digital Aerial Survey.
