Program accomplishments

  • Petaluma River Greenway - Friends is working to permanently protect the upper Petaluma River through a campaign to purchase and restore an almost 2-mile stretch. This project would provide habitat restoration, public access to nature and outdoor recreation, flood protection and climate change mitigation among other community benefits.
    Expenses $147,468
  • Summer and Day Camps - Friends operates a successful summer camp called the Green Heron Nature Camp for 5-12 year olds that gets kids outside exploring nature through paddling, hiking, swimming, crafting, games and play. During the school year, Friends offers weekend camps for youth each month. Of the roughly 400 youth who participate in Friends' camps each year, 1/4 do so through free scholarships made possible by donors.
    Expenses $146,275
  • Watershed Classroom - Friends works in approximately 10 local schools to get kids outside, learning about their local environment through hands-on, experiential curriculum. With a focus on Title 1 schools, Friends works to ensure that all students have access to outdoor, nature-based experiences and environmental education.
    Expenses $97,453
  • Steamer Landing Park is City-owned, open space park in downtown Petaluma along the banks of the Petaluma River.

    Expenses $19,350
  • Petaluma River Cleanup - Friends conducts two large river cleanups each year with about 200-300 volunteers working at 10-15 locations in the watershed. These cleanups regularly remove 2,000-5,000 lbs of trash from our waterways. Friends also works with schools, businesses, civic organizations and others to provide volunteer river cleanup experiences for smaller groups. Each year, Friends river cleanups remove an average of 10,000 lbs. of trash from the Petaluma River and its tributaries.
