This data set contains the community-wide greenhouse gas emissions over time. The emissions are broken down by sector (e.g. transportation, waste, etc.), and by emissions source (residential buildings, commercial buildings, on-road transportation, etc).

This dataset identifies the Natural Water Bodies on lands under Calgary Parks Stewardship. It can be a flowing type of water i.e. STREAM or some type of body of water i.e. NATURAL POND. Types of WATER BODIES are: CREEK – CONSTRUCTION, NATURAL CREEK OR STREAM, NATURAL RIVER, OXBOW, NATURAL LAKE, NATURAL POND, SPRING, and WETLAND.

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

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.

(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 1/5 or a 20% 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.

Relative vulnerability ratings of areas in Calgary's source watersheds. For more information, visit: http://www.calgary.ca/UEP/Water/Pages/Watersheds-and-rivers/Souce-Water-Protection.aspx

If a land use change or activity were to cause a release of contaminants, the vulnerable areas map indicates which areas are more or less vulnerable to facilitating the movement of contamination to surface waters downstream.

The "Final_rating" field is used to map the 5 categories. Please see the User Guide for detailed field descriptions:
