Commercial and Multi-Family Lot Grading

The Drainage Bylaw No. 16200 provides lot grading and site mechanical requirements for the development of commercial and multi-family properties.

The purpose of lot grading is to provide good drainage away from buildings for the benefit of property owners. The purpose of the Drainage Bylaw No. 16200 is to regulate surface drainage on private and public land.

Lot grading for Commercial and Multi-family properties is the shaping or sloping of the land in such a way that surface drainage is directed away from the buildings and controlled within the property in a manner that eliminates impact on adjacent properties and City right-of-way.

Along with an application for a Development Permit for any land zoned Commercial, Industrial, Multi-Family, Apartment or Row Housing, the developer must submit a proposed Lot Grading Plan for review and approval.

The Lot Grading Plan must be approved by the City Manager prior to the construction of any buildings, additions to buildings, or alterations of surface drainage. This plan specifies design elevations, surface gradients, swale locations, and a relationship between adjacent properties and its approval is an effective basis for the control of surface drainage.

The Commercial Lot Grading Guidelines provide the procedures and requirements for surface drainage.

For Residential Lot Grading, more information can be found in Lot Grading Guidelines for Residential Properties.
