Lot grading, which involves ensuring a level base or securing a specific slope on the land, is important for protecting the foundations of homes and buildings from basement flooding and other water damage. Explore the requirements for grading and drainage plans, along with the relevant by-laws.
Please note: Applications are not deemed complete until approval through third party review.
Important: Lot grading cannot be completed in the winter.
When a Grading & Drainage Plan is Required
A Grading & Drainage Plan may be required if you are applying for a Building Permit, Planning Act Application, Entrance Permit or other cases where site alteration is proposed.
Third Party Review
Your Grading and Drainage Plan will be reviewed by our third-party engineer to determine whether the proposed plan will negatively affect the neighbouring properties or municipal boulevard. Our third-party engineer will communicate with the applicant’s engineer until a desired grading and drainage plan is agreed upon through the use of a checklist.
