Rain, Runoff, and Lawn Care Safety

When it comes to lawn care in Edmonton, rain and water management aren’t just a matter of timing; they’re at the heart of strict regulations designed to protect our stormwater system and the North Saskatchewan River. Here’s how the law works, what it means for property owners, and how Neighbourhood Heroes leads the way in delivering safe, reliable, and environmentally responsible service.

Why Do Rain and Runoff Matter in Lawn Care?

Pesticides and herbicides used in lawn maintenance can be carried by rainfall or irrigation runoff into storm drains, which flow directly into natural rivers and streams, rather than being treated at a treatment plant. That’s why Edmonton’s laws strictly govern every aspect of their use, from application timing to storage and disposal.

Key Regulations Protecting Waterways

 1. No Contamination or Run Off

City of Edmonton Drainage Bylaw (Bylaw 18093): Absolutely prohibits any discharge of pesticides, herbicides, or similar hazardous materials into storm sewers.

Adverse Effect Clause (Provincial Environmental Protection and Enhancement Act): 

Applying or moving pesticides in a manner that harms the environment, including through runoff, can result in severe fines for both individuals and businesses.

2. Strict Federal Law

Federal Fisheries Act

Prohibits pesticide contamination of fish-bearing waters, even indirectly, such as via surface runoff or wind drift. Protecting streamside vegetation is also required by federal law.

Buffer Zones and Restrictions Near Water

30-Metre Buffer (Undeveloped Land): On undeveloped land, you cannot apply pesticides within 30 metres of open water without “Special Use Approval.” 

Managed Turf Exemptions: For lawns and landscaped areas, buffer zones must follow label requirements, usually several meters from water bodies, and every applicator must be vigilant to prevent runoff.
