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

These maps provide landfill setback information as defined under the Municipal Government Act (MGA) Subdivision and Development Regulation (SDR) Landfill Setback (Section 13) from a City of Calgary Landfill or Waste Management Facility (WMF). The file contains the landfill setbacks for the following City of Calgary Landfills: East Calgary WMF, Shepard WMF, Spyhill WMF, Blackfoot Landfill, Highfield Landfill, Manchester Landfill, Nose Creek Landfill, Ogden Landfill, and Springbank Landfill. For more detailed information on the landfill setbacks, contact Waste & Recycling Services.

Information about Calgary's urban forest, including the locations and types of trees on public land.

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.

Depicts basic components of The City of Calgary's 2007 Environmental Reserve (ER) Setback Guideline policy, including the base setback based on stream order, and the additional setback modifier based on slope. This can be used as a starting point to scope out riparian-associated ER requirements for planned future developments. It can also be used within existing built areas of the city to highlight past lost ER opportunities.

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.

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. There may be some error in the extents shown due to the method used for creating the line from the aerial photo (interference of trees, shadows, etc. when interpreting the location of flood water in the photo).
Export as Shapefile or GeoJSON.

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)

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.
