(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 1/20 or a 5% 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.

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.

Using data collected in 2018, 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 2018 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 326 MB. The uncompressed files are 3.95 GB. Data is arranged in Townships, with 21 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.

Depicts recommended riparian area management category zones along the major rivers and streams of Calgary. These categories are meant to guide land use planning, park management, and river engineering decisions. The spatial mapping of these categories also complements the Riparian Decision Matrix for River Engineering Projects, with the purpose of ensuring bioengineering practices are applied to the maximum extent feasible within The City of Calgary.

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

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.
