Water Resources Redevelopment 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.

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.

Cathodic Protection requirements for The City of Calgary

In the Province of Alberta, the Apprenticeship and Industry Act (AIT) regulates the minimum certification requirements for any workers performing certain cathodic protection (CP) functions.

Therefore, if The City of Calgary has not explicitly stated that worker certifications are required for projects (including CP scopes of work), then it is at the contractor’s discretion to determine whether a CP sub-contractor is required or whether the contractor is competent in performing the functions based on AIT’s CP Technician Regulati​ons​​.

Mandatory CP Documentation

If you are a contractor or an engineering consultant involved with a City of Calgary construction project that has a CP component in its scope of work, the applicable documents must be utilized and be readily available upon request by a City of Calgary CP inspector.

The City’s Cathodic Protection Division has implemented a revised quality management system which includes the use of Inspection & Test Plans (ITP) and Quality Assurance/Quality Control (QA/QC) documents. The purpose of this system is to assist contractors in maintaining consistent levels of quality with CP system construction projects that meet City of Calgary standards.

A digital copy of the completed and signed off documents must be submitted electronically. The original hard copies must be included in the project turnover package. Incomplete or partially signed-off documents submitted will not be accepted.

Any inquiries/questions regarding the use of the documents or submission process can be directed to Cathodic Protection.
