The Impervious Surface 2021 dataset is a collection of polygon features derived from Calgary Digital Aerial Survey mapping linework which have been determined as impervious. Impervious surfaces are defined as any material which will seal the soil surface, impede water infiltration, collect solar heat or deprive tree or vegetation roots of aeration. Impervious surfaces effect many aspects of our City, including storm run off volumes, pollutant concentrations and drainage. The City must understand and manage the amount of impervious surfaces carefully to ensure the ongoing health and vitality of the municipality and the environment.

This dataset is compiled from The City of Calgary’s in situ (in location) water quality monitoring program. In situ field measurements are acquired from the deployment of multi-parameter sondes in surface waters by The City of Calgary. Measurements are collected using two methods: Continuous and Discrete.
Continuous: In situ measurements logged at regular intervals (e.g. 15 minutes) for an extended period of time.
Discrete: Individual in situ measurements manually collected by a field technician.
Parameters that are measured include, but are not limited to: dissolved oxygen, water temperature, pH, turbidity, and specific conductance. Monitoring locations, intervals, and water quality parameters vary per site and period, depending on the monitoring objectives at the time of deployment. Multi-parameter sondes are routinely calibrated as per manufacturer’s specifications and verified against independent standards.

This data is not a live data feed. It is manually retrieved, reviewed, and posted at regular intervals. Field data is not altered or adjusted, though any data that is determined to be invalid based on sensor interference, sensor failure, or damage, has been removed from the final dataset.

Monitoring records are reported in the local time zone at the time of measurement for Calgary, Alberta (MDT/MST).

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:

(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 1/50 or a 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. Any use of this data must recognizing the uncertainty with regards to the exact location and extent of flooding.
