The Lot Grading Certificate for both Rough Grade and Final Grade approvals must contain the following information and the example drawings showing as a reference for the general requirements for Typical Rough Grade and Lake Lot Final Grade:

•  Surveyed by
        Alberta Land Surveyor
        Professional Engineer or
        Registered Architect


•  Name of the company that produced the Certificate


•  Legal Description and Municipal Address of the property


•  Surface Condition of the Lot such as clay, topsoil, sod, or landscaped


•  Note indicating that the Lot Grading is subject to the approval of the Local Authority


•  Design and existing elevations referenced to metric geodetic datum with an asterisk (*) designating existing elevations that exceed the grade tolerance


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


•  As-built of the adjacent property, if landscaped, at the design elevation locations


•  As-built property-line (swale) elevations opposite the corners of the building, for locations that are more than 3 metres from a design point


•  As-built high point elevation on split grade lots, if location is different from the design


•  Foundation grade elevations with an additional elevation of 2-3 metres from the back of the house


•  Drainage Easements and Right-of-Ways

If there is an approved Surface Drainage Plan (Lot Grading Plan) for a subdivision, a Lot Grading Certificate is required for both rough and final grade approvals. This requirement is outlined in the Surface Drainage Bylaw.

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 existing elevations if the existing elevations on the Lot Grading Certificate are not within tolerances.


•  Discrepancies or errors in design and/or existing 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 (e.g. an approval for front landscaping when the back yard is still in rough grade).
