from 1:00 – 3:00 pm.

The March 15th work party has been cancelled.

Our staging area will be the Brookside trailhead. Crew leaders will greet and help you in these invasive species removal projects. At each session, some aspect of the park will be highlighted so everyone will take away some insight besides dirty clothes!

Garden naturally:

Lake Oswego Backyard Habitat Certification Program

Soak up stormwater runoff:

  • Rain gardens slow down and soak up stormwater runoff on your property.

Watershed-friendly household maintenance:

  • Soak up driveway spills with kitty litter and throw in the garbage
  • Sweep your driveway instead of washing it
  • Dispose of household hazardous waste at a disposal facility – drains in the street lead to local streams

Maintain your vehicles to reduce pollution:

  • Fix vehicle fluid leaks to keep them from washing into streams
  • Wash your car at a car wash or over grass

Even your pets can help:

  • Please pick up after your pets – bacteria from dog waste pollutes our waterways
