A lot grading certificate is required for grade approvals for all developments including infill housing

Rough and/or final grading certificate submission is required to ensure that the grading for a property conforms to the requirements of the Drainage Bylaw No. 18093 and the lot grading guidelines.

Issues Requiring a New or Revised Certificate

The lot grading inspector could ask for a new or revised lot grading certificate when any of the following occurs:

  • Errors, incomplete or unclear information on the lot grading certificate

  • Verification of as-built elevations if the as-built elevations on the lot grading certificate are not within tolerances

  • Verification of as-built elevations, if requested by the inspector, due to substantial re-grading

  • Discrepancies or errors in design and/or as-built elevations that require confirmation

  • Red-line revisions to the lot grading plan that are not reflected on the lot grading certificate

  • Application for partial approval on final grade (for example, an approval for front landscaping when the back yard is still in rough grade)
