10 Lot Grading Tips (PDF 1.90 MB)

It's the contour of the surface of your lot. The lot grading should generally direct water away from the foundation and towards public property.

The City of Grande Prairie's Lot Grading Bylaw C-1240 (PDF 35KB) requires any new residential or commercial developments to design the lot elevations on their parcel in accordance to the approved drainage plan and Bylaws C-1240 and C-1241. Any major redevelopments or any work being done that may significantly alter the onsite drainage must also abide by these Bylaws.

Engineering Services is working to prepare a new lot grading bylaw to allow for better management of both Residential and Commercial Lot Grading. This draft can be viewed here.

Residential Properties

Residential Stormwater Drainage Systems

There are typically three drainage systems to consider on residential properties:Drainage

  1. Foundation Drainage (weeping tile, sump pumps)
  2. Roof Drainage (downspouts, slash pads) 
  3. Surface Drainage (lot grading)

Residential Submission Requirements
