Historical Rainfall

This is a historical record of 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. For current year, raw rainfall readings see [Current Year Rainfall]
Historical Property Assessments (Parcel)

The historical assessed values of residential, non-residential and farm land properties in Calgary. The properties in this dataset consist of Calgary lands that have a registered parcel at Alberta’s Land Titles Office. Properties that are on The City of Calgary’s annual property assessment rolls, but excluded from this dataset, are titled parking stalls, titled storage units, machinery & equipment property, and linear property (as defined in the Municipal Government Act). *You may see leading 0's removed in downloaded files. Please see attachment [How to keep leading zeros] for more information. **For detailed property assessment information, visit [Assessment Search] **
Historical Community Populations

The population, occupied dwelling count, and person per unit calculation of Calgary communities since 1968. These data are collected from different sources and may be based on community boundaries that do not align perfectly with current boundaries. Data from 1968-1977 and 2016-present reflect community boundaries in those years. Data from 1978-2015 are based on the community boundaries in 2016. Where community boundaries have changed substantially over time, this is captured in the "notes" column. Population and dwelling unit totals do not include "Residual Sub Areas", so they may differ slightly from the totals published in official Civic Census records.
Historical Air Quality

This dataset makes historical air quality data accessible for various parameters at Calgary monitoring stations. The data is collected by the Calgary Region Airshed Zone and submitted to Alberta Environment and Parks (AEP). The data is delivered to the airdata warehouse, a central repository for Alberta's ambient air quality data via a web service provided by AEP. In this way, AEP provides access to quality controlled historical air quality data at its air quality stations. In addition to air quality monitoring data, an Air Quality Health Index (AQHI) is calculated hourly at certain monitoring stations. The AQHI is a simple way to interpret air quality conditions: it provides a number from 1 to 10+ which indicates the relative health risk associated with local air quality. The higher the number, the greater the health risk. Further information on the AQHI calculation is available at: https://www.alberta.ca/air-quality-health-index--calculation.aspx
Green Buildings Priority Stream – Constructed Building Performance

This dataset provides project‑level information for completed buildings participating in the City of Calgary’s Green Building Priority Stream (GBPS). Each record represents a single building permit for a project that has reached construction completion and includes key building characteristics such as entry pathway, floor area, construction value (where disclosed), and modelled energy, greenhouse gas (GHG), and energy cost performance based on documentation submitted at the building permit stage. The dataset includes residential and non‑residential buildings completed between 2022 and the current date, covering multiple performance pathways, including NECB‑based compliance, Net Zero Ready Homes, Net Zero Homes, and Zero Carbon Buildings. Projects that are currently under development or permitted but not yet constructed are not included. As a result, the dataset represents a subset of total GBPS participation and does not capture the full pipeline of projects enrolled in the program. All energy, emissions, and cost values reflect proposed or modelled design performance at the time of permit and may differ from measured operational outcomes once buildings are occupied. The dataset is intended to support program reporting, research, and high‑level policy evaluation, rather than project‑specific compliance verification. The data is subject to the following considerations: 1. Emissions Factors Electricity emissions factors reflect Alberta’s grid mix and may change over time. The natural gas emissions factor (0.054 tCO₂e/GJ) represents a standard combustion value. 2. Energy Costs Energy costs are based on estimated blended electricity and natural gas rates anchored to 2025 values and indexed across other years using a constant annual escalation rate. These estimates may not reflect current or site‑specific utility tariffs. 3. Solar PV Solar electricity is valued at an energy‑only rate and does not offset the full blended electricity rate. No premium export programs or solar club rates are assumed. 4. Modelled Performance Energy, emissions, and cost results are derived from energy modelling and may differ from actual building performance due to operational, weather, and occupant factors. 5. Reference Buildings Percentage savings are calculated relative to a code‑minimum reference building (NBC‑AE 2023 or NECB 2020) and represent estimated, not guaranteed, performance. 6. Data Completeness, Currency, and Use Construction value and other project attributes are self‑reported at the time of permit submission and may be incomplete or withheld for some projects. This dataset is provided “as is” and reflects information available at the time of publication. Data and assumptions may be updated periodically as additional completed projects become available or methodologies are refined.

Flood extents from June 22, 2013

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)

Community Disorder Statistics

In addition to monitoring crime levels, the Calgary Police Service uses a range of types of calls for service (CFS) to monitor levels of "Disorder." Research indicates that disorder can have a negative impact on public perceptions of safety. Disorder is often highly visible, occurring in public spaces; drunks, panhandling, youth gangs, prostitution, littering, loitering and graffiti are examples of signals of social and physical disorder. A very low proportion of disorder-based calls for service result in crime reports. Disorder CFS included are: Drunk, Disturbance, Indecent Act, Landlord/tenant, Mental health concern, Neighbor dispute, Party complaint, Suspicious person, Threats, Drugs, Noise complaint, Possible gunshots, Unwanted guest/patron, Prostitution, Speeder. Please note there has been an update to the methodology for disorder in January of 2024, including the removal of property damage and Abandoned auto, resulting in the dissolution of disorder sub-categories. Disorder counts will therefore not be directly comparable to previously published disorder reporting. Only public-generated call types are included: Advised, Callback, and Dispatched (police-generated calls are excluded). All dispositions are included. Events are assigned to communities based on the geocode in CAD. Count is by single event. Data source: Computer Aided Dispatch (CAD) run on the 4th of the month (or the closest business day) for the previous month. This data is considered to be static. Property Damage occurrences reported using the online reporting system are included from the CPS records management system (SENTRY). This data is considered to be cumulative.
Community Crime Statistics

As of 2024, data is no longer provided by the Calgary Police Service. To access latest data [click here]. This data is considered cumulative as late-reported incidents are often received well after an offence has occurred. Therefore, crime counts are subject to change as they are updated. Crime count is based on the most serious violation (MSV) per incident. Violence: These figures include all violent crime offences as defined by the Centre for Canadian Justice Statistics Universal Crime Reporting (UCR) rules. Domestic violence is excluded. Break and Enter: Residential B&E includes both House and ‘Other’ structure break and enters due to the predominantly residential nature of this type of break in (e.g. detached garages, sheds). B&Es incidents include attempts.
Citywide Land Cover

This is a composite land cover layer created from multiple City data sources and compiled into a single seamless land cover layer in 2015. The final land cover layer was checked against the City of Calgary’s 2014 air photo at a minimum of 1:4000. Missing and/or overlapping areas were resolved manually and City parks were reviewed at 1:1000 resolution. The land cover dataset informs several City analyses, including a Habitat Condition Rating model to assess natural area park health and a structural wildlife connectivity model, where land cover resistance values act as the difficulty rankings for terrestrial wildlife movement. The dataset can also be used in analyses of open/park space contiguity. Export geospatial file as [GeoJSON] or [Shapefile].
