A Lot Grading Plan (Surface Drainage Plan) has been a part of the approval process for commercial and multi-family properties since 1993. The plan is required for new developments and approved by the City of Edmonton, Development Services on behalf of City Council.

This plan specifies design elevations, surface gradients, swale locations, and other drainage information required for lot grading. The approval of this plan provides an effective basis for lot grading control which will establish the drainage relationship between abutting properties.

The example drawings of Lot Grading Plans for multi-family, typical commercial, and shopping centre provide general information of what should be shown on the plan (for reference only).
