The purpose of lot grading is to shape the land to direct storm water away from buildings and towards a City right-of-way. This assists in protecting buildings and properties from storm water drainage issues and is regulated through Drainage Bylaw 18093.


The Residential Lot Grading Guidelines are intended to assist property owners, homebuilders, and contractors with successful planning and execution of lot grading approvals, including infill plan approval, inspections and compliance with Drainage Bylaw 18093 .

This includes information on site grading during the land development process, explaining the lot grading approval process, as well as stating the lot grading requirements for all single detached, semi-detached, duplex and row house developments. Site servicing requirements and special information for infill developments are also explained in this guide.
