Upcoming Events

National River Cleanup Day in Sunnyvale

May 20
9 a.m. to noon

Meet at Baylands Park

Our Creeks and Waterways Need Your Help

Did you know that last year volunteers picked up more than 30,300 lbs. of trash from creeks in Santa Clara County for National River Cleanup Day? These trashy creeks need our help!

This year’s event in Sunnyvale will focus on picking up litter and debris from the Sunnyvale East Channel, Calabazas Creek and areas around Baylands Park.

Youth under the age of 18 must have parental approval and anyone age 15 and under must be accompanied by an adult. This event may not be suitable for young children due to steep banks in some areas.

Register at Eventbrite. For more information, call 408-730-7717, TDD 408-730-7501 or email us.
