Commercial & Multi-Family Site Grading
Commercial and multi-family site grading throughout the City of Saskatoon is regulated as per Bylaw No. 9772 – The Drainage Bylaw, 2021. The information below outlines the requirements and approval procedure for site grading associated with commercial building permits.
A site grading plan is required as part of the commercial building permit application. In addition, effective October 1, 2021, the City requires a final site grading inspection for all new commercial and multi-family developments that require site grading.
Any building permit application, including commercial, multi-family, and institutional forms of development, received after October 1, 2021 will be required to follow the commercial/multi-family site grading procedure outlined below.
Commercial Site Grading Procedure
- Your property must be surveyed by a professional land surveyor and a site grading plan prepared by a qualified professional. See Commercial Site Grading Plan Requirements for details.
- Submit the site grading plan as part of the building permit application.
- The site grading plan will be reviewed prior to the issuance of a building permit.
- Rough Grade Inspection (optional)
- The developer is responsible to schedule an inspection at the rough stage if desired.
- Rough grading may be reviewed on site with a drainage inspector.
- If alterations are made to rough grading, that are not indicated on the approved site grading plan, then you are required to re-submit the site grading plan for approval.
- As-built Drawing Submission (mandatory)
- The developer is responsible for completion of a final site as-built survey by a professional land surveyor.
- A final site as-built drawing is required to be completed by a professional land surveyor, engineer, or architect and submitted to email@example.com.
- Site grading plans issued for construction that are re-stamped as as-built drawings will not be accepted.
- Final Grade Inspection (mandatory)
- After the as-built drawing has been received and the developer has requested a final inspection, a drainage inspector will inspect the site to confirm compliance with the approved site grading plan and complete a site grading inspection report.
- Deficiencies will require correction and re-inspection.
- If deficiencies are not corrected, enforcement action may be taken in accordance with the Drainage Bylaw.
- Final grade approval is required to be obtained within 9 months of the building permit closure, occupancy, or partial occupancy of the site – whichever occurs earlier.
