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.

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 became mandatory for all new submissions received as of Sept. 1, 2012.

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

It covers 1960 through 2009; it will be updated every few years. A more in-depth explanation of the changes made is in the spreadsheets containing the data.

Inspections of water utility infrastructure under the Master Development Agreements and Interim Indemnification Agreements follow the Consulting Engineer’s Field Services Guidelines.

The Guidelines are currently under review to provide more clarity around inspection requirements and further enhance the inspection processes. In addition, inspection fees and fee structures are being reviewed for adjustments to better align with service level agreements.

Cathodic Protection

Water Resources is implementing an enhanced quality assurance checklist for Cathodic Protection Installation via the use of aCP Test Plan Checklist.

This checklist is intended to identify and formalize the inspection and sign-off on all necessary installation steps to achieve the CCC and FAC Acceptance of more complex Cathodic Protection Installations, such as those required by LRT or water and sewer construction that includes the establishment of a permanent cathodic protection Test Point.

New Submissions are subject to the use of the checklist, and where applicable, will be required by Development Approvals to submit a Detail, such as showing the installation of a permanent CP test station.
