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 16200 and the lot grading guidelines.

These examples reference the requirements for a typical rough grade and lake lot final grade.

All Certificates must display the following information:

  • Certification by a professional acceptable to the City Manager (for example, an Alberta Land Surveyor).
  • Title – Rough Lot Grading Certificate or Final Lot Grading Certificate

  • "Revised" added to certificate titles for revised certificate submissions

  • Date as-built elevations were obtained

  • Lot type, obtained from the approved lot grading plan - type A, type B, type D, type D/T, type W, type W/T, and so on.

  • Name of the company that produced the certificate

  • Proof of professional liability insurance for errors and omissions for the corporation or individual named on the certificate

  • Legal description and municipal address of the property

  • Surface condition of the lot, such as clay, topsoil, sod or landscaped

  • A note indicating that the lot grading is subject to the approval of the local authority

  • Design and as-built common property drainage swale and any side-lot internal swale invert elevations referenced to metric geodetic datum, with an asterisk (*) designating existing elevations that exceed the grade tolerance

  • Reference to the Alberta Survey Control Monument that was used to obtain as-built elevations

  • As-built elevations of structures, such as retaining walls, sidewalks, driveways, fences and garage/parking pads

  • As-built common property drainage swale and any side-lot internal swale invert elevations opposite the corners of the building, for locations that are more than 3 metres from a design point

  • Any break point elevation

  • House corner and rear foundation grade as-built elevations, including an additional elevation 2 metres from the back of the house. Also, provide the design elevation for finished grade at back of house

  • Drainage easements and right-of-ways with as-built invert and lip elevations, as required, for any concrete or grass drainage swale inverts

  • Detail certificate of lake lot with all structures or feature locations and as-built elevations within the maintenance and overflow area

    Lot orientation is portrait, with the rear of the lot at the top of the page, and the front of the lot labelled (this format supports the location references in the grading reports)

  • Presentation on 8 ½" x 14" (legal size) format

  • Scale of drawing

  • House and garage/parking pad layout, including garage pad design elevation

  • North arrow

  • Legend

  • Name and information of the applicant for the preferred method to receive inspection reports or grading approval (mail, fax or email)

  • Sworn oath validating the accuracy of the as-built elevations obtained by closed level circuit related to known elevations of benchmarks reference to geodetic datum

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)
