In some neighbourhoods, complications may arise between neighbours if drainage is not properly designed. Most problems can be resolved with open communication. Neighbouring property owners have an equal interest in effective drainage of surface water.

The City's representatives (lot grading inspectors) are not mandated to act as dispute arbitrators, but are available to investigate surface drainage problems and enforce the provisions of the Surface Drainage Bylaw. If you are experiencing problems, there are several things you can do:

•  Check your own surface drainage, and see our Frequently Asked Questions for answers to your questions about common drainage disputes.

•  Talk to your neighbours to work out solutions. They may not realize there is a problem.

•  Contact a professional, such as a landscaper or foundation drainage expert.

•  If property has been damaged, try mediation (see related links) before you consider legal action against the offender.

If you're unable to settle on satisfactory drainage arrangements, you can contact the City to investigate. A lot grading inspector will examine surface drainage conditions on both properties and make recommendations for improvements.

A Letter of Non-Compliance or Notice to Comply will be sent for infractions of the Surface Drainage Bylaw. Property owners must then take steps to bring their property into compliance with the bylaw, or face fines.

For an older neighbourhood without Lot Grading Plans, you can refer to the Information Guide for Surface Drainage Problems for more information about lot grading requirements, and how to resolve surface drainage problems.
