Guidelines

What to Submit

  • Checklist #18 - Rainwater harvesting
    • 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.

New and revised stormwater management report submission requirements

All e-stormwater submissions must contain the full report with all required checklists, information, and stamps.

POSEIDONOnline electronic submissions must contain all required information and attachments for a review. If any information or required attachements are missing the submission will be rejected. No partial applications will be accepted.

E-Stormwater reports are submitted directly via POSEIDONOnline.

If an applicant is submitting both the E-CD and E-SWMR concurrently, the E-CD must be submitted first.

If the E-CD is in circulation and the E-SWMR is being submitted at a later date, there is the ability to synchronize the E-CD to E- SWMR submission. The same applies if the Subdivision stormwater management report is already in circulation and an E-CD is being submitted at a later date.

Amendments to subdivision stormwater management reports and private site stormwater management reports.

Amendments to subdivision and private site stormwater management reports can be submitted to Water Resources via POSEIDONOnline using the revised final E-stormwater report process.

If a report number does not appear, in particular for Private Sites, please contact: IPInformationManagement@calgary.ca.

Final and revised final stormwater management report submission requirements

To ensure the SWMRs available on City Online are the most recent, approved version and to make the reports more user friendly, Water Resources requires a clean copy of final and revised final SWMRs be provided after the no objections letter has been received.

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 SWMR 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.
