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.

Identifies variable width biophysical riparian areas along major rivers and streams in Calgary, as of 2012. Four separate riparian zones are delineated: Inner Riparian, Middle Riparian, Outer Riparian, and Potential Outermost Riparian. Boundaries are based on city-wide models driven by distance from the river/stream, slope profiles from digital elevation models, and field work calibration based on sampling of riparian plant community locations. Note that the methods identify both developed and undeveloped riparian areas.

This dataset contains a forecast of the total population and jobs in each transportation zone from 2014 to 2076. This forecast series is a backcast scenario to achieve growth targets identified in the Municipal Development Plan. (www.calgary.ca/mdp)

(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 1/500 or a 0.2% 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.

Calgary Public Library offers four types of Library tours. Each one provides you with a different experience of the Library and its resources.
