Lot Grading Certificates

A Lot Grading Certificate is required for Rough and Final Grade approvals for all properties that have an approved Lot Grading Plan. For Mature (In-fill) Housing Development, where there is no approved Lot Grading Plan, Rough and Final Grading Certificate submission is also required to conform to the requirements of the Surface Drainage Bylaw and the Lot Grading Guidelines. The example drawings demonstrate as a reference for the general requirements for Typical Rough Grade and Lake Lot Final Grade:

The Certificates must display the following information:

• Certification by
  Alberta Land Surveyor
  Professional Engineer or
  Registered Architect
• 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 property line 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 property-line 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
• Corner foundation grade as-built and rear foundation grade as-built elevations. Including an additional elevation 2 metres from the back of the 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 Survey of lake lot with all structure 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)
• Date of as-built survey
• Scale of drawing
• House layout
• Garage/Parking pad layout
• North Arrow
• Legend
• Name and information of the applicant for the preferred method (mail, fax or email) to receive inspection reports or grading approval

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 (e.g. an approval for front landscaping when the back yard is still in rough grade)
