Come out and do your part to clean up McNabney Marsh for our California Coastal Cleanup Day 2026 event on Sunday, September 27th, from 9:00 am-12:00 pm. Data collected at Coastal Cleanup events helps support legislation to address waste in our state, including plastic bag bans. Be a part of this important effort!

This is a marsh close to the waterfront, so please dress for windy weather and wear clothes that can get wet and/or muddy. Wear long pants, durable shoes, and sun protection (hat and/or sunscreen). Please bring a reusable water bottle if you have one. Snacks and water will be provided. 

Further information will be sent to those who register prior to the event.
