Lot Grading Approvals - Commercial and Multi-family

The City requires new developments to conform to the approved Surface Drainage Plan (Lot Grading Plan). Therefore, when applying for a development permit for land zoned for any use other than single detached housing or semi-detached housing, the developer must submit a Lot Grading Plan (Surface Drainage Plan) to Drainage Services for approval.

In addition, once final grade is established or landscaping is complete, Final Grade Approval is also required.

Approval Process

The Grading Approval Process (Final Grade) should occur within 18 months of the Approval of the Lot Grading Plan and applied for by the owner, developer or contractor (applicant). The following steps are required to obtain Final Grade Approval:

1. The lot has to be surveyed (on sod or topsoil) and certified by an Alberta Land Surveyor, Professional Engineer, or Registered Architect who prepares a Plan of Certification of As-built Grade (Lot Grading Certificate). The as-built information MUST BE displayed on the Lot Grading Plan.
2. The applicant sends the certified As-built Plan (Lot Grading Certificate) to Drainage Services of Financial Services and Utilities.
3. Lot Grading Inspector will conduct an inspection within 5 working days (depending on workload and weather conditions) to ensure that the property is graded in accordance with the approved Lot Grading Plan.
4. Lot Grading Inspection Report will be sent to the applicant, indicating that the lot grading has received Final Grade Approval (Passed) or deficiencies exist (Failed).
5. If deficiencies exist, the applicant must correct the deficiencies within 60 days and notify Drainage Services for a re-inspection.
6. When the lot grading meets our requirements, Final Grade Approval will be issued.
7. When the Final Grade is approved, Drainage Services will send an approval report and a copy of the Lot Grading Certificate to the applicant.
