The concrete pad for a detached garage or other building is elevated to provide positive slope way from the building. Proposed grade elevations for pads are a design requirement and are presented on the Lot Grading Plan that is submitted with the application for the Development Permit.
The Lot Grading Plan must indicate how the water will be handled on the site whether it is through a common property swale, an internal swale or a retaining wall. The Town of Slave Lake does not require the Lot Grading Certificate to show proposed grades throughout the entire lot. However, proposed grades shall be shown around the detached garage/building and around the side of the main building abutting the new structure.
