Water resources development strategy

The redevelopment strategy sets out the objectives and actions water resources will take to improve support of redevelopment in established areas in the city.

For more information about the strategy please see this Redevelopment bulletin

Neighborhood specific infrastructure reports

As part of our redevelopment work, water resources is preparing a series of neighborhood-specific infrastructure reports, to be made publicly available online.

The reports assist in preliminary infrastructure due diligence investigations related to potable water, sanitary, and storm servicing prior to redevelopment of a site by land owners, developers, and/or their consultants.

This information may be useful at various stages in the development process to help better understand broad, community-scale infrastructure context, from land acquisition through to conceptual design work or prior to a formal application for land use re-designation or development permit.

As a starting point, the grain of detail contained in this report can provide a basic understanding of key infrastructure features in the community that may be useful for those seeking to develop or redevelop a site.

Precipitation and temperature data files

Water resources has made available hourly precipitation and temperature data files for the analysis and design of stormwater infrastructure in Calgary.

These data files are an adaptation of the Environment Canada, Meteorological Survey of Canada data, error-checked and reconciled with local weather observations.

They cover 1960 through 2009 and will be updated every few years. A more in-depth explanation of the changes made is in the spreadsheets containing the data.

Using this data eliminates discrepancies due to different datasets being in circulation, thus saving time for both design professionals and water resources.

Use of the information in these data files is mandatory for all new submissions received as of Sept. 1, 2012.

This information has no legal status and cannot be used as an official interpretation of the various bylaws, codes and regulations currently in effect. The City of Calgary accepts no responsibility to persons relying solely on this information. Web pages are updated periodically. ​
