Stormwater Report Templates

Stormwater Management Report (SWMR) Templates were created to help Engineering Consultants work through the development of their SWMRs. The templates provide further information including:

Please note: The "Comprehensive Guide for Rainwater Harvesting as a Stormwater Best Management Practice", referenced in the Rainwater Harvesting Guidelines published by Development and Building Approvals (DBA) is currently under development.

Should more information pertaining to the Guide be required, inquiries can be sent to Bert van Duin at bert.vanduin@calgary.ca. Once the Guide is completed, an Industry Bulletin will be released.

The clean copy of the final or revised final SWMR should include the following:

  • Report cover date should match the date the clean copy is being submitted.
  • Appropriate Stormwater Management Report checklist with certification from a Professional Engineer.
  • A copy of the no objections letter is required as the first page.
  • All previous comments and requirements should be addressed and incorporated into the report, with no mark-ups. All updated drawings, models, etc should be incorporated.
  • For Revised Finals, the previous, most recent approved version of the report, prior to the changes should be included as an Appendix.
  • Any previous correspondence that is relevant should be included as an Appendix.

The Final and Revised Final Stormwater Management Reports should be submitted electronically directly via POSEIDONOnline.
