One Drawing Saves You Dollars – Lot Grading Plan for Permits & Construction


A Lot Grading Plan shows proposed grading patterns around a new structure, including drainage directions, swales, retaining walls, and slope adjustments to ensure proper surface drainage. It's typically required for building permits to prevent water damage and negative impacts on neighboring properties. After construction and landscaping, a site inspection is conducted, and an Ontario Land Surveyor issues a Lot Grading Certificate confirming compliance.
