Lawn care resources 

Why go chemical free? 

  • For the health of our community, keep a pesticide-free lawn and garden. It’s easy and helps keep harmful products away from people, pets and our streams. 
  • Lawn and garden chemicals can remain on your lawn for days or months, can get tracked into your home, and may be harmful to humans and pets. 
  • Pesticides can kill pollinators and soil microbes critical to healthy gardens.  
  • Residential lawn chemicals have been found in our urban rivers and streams, many at alarming levels.   
  • Even natural/organic products can pose a risk to pollinators. Read product labels and watch the weather forecast to apply safely. 
  • Keep our water safe for recreation and for the iconic salmon who live here.
