Many of the people caring for Sonoma County's creeks aren't paid to.
We're new here too. So we went looking for who already does the work. Most would be glad to see a new face.
You don't have to do it all. Type your address for a short plan: one thing to show up to, one list to join, one meeting for later.
Find your watershed
- Type your address, or tap anywhere on the map.
- Your home area lights up, along with the path your rain takes to the sea.
- Tap a nearby watershed below the map to see the one over the ridge.
Type an address, or tap anywhere on the map.
Each area with a thin white outline is a subwatershed, the smallest kind. Darker gray lines group them into larger watersheds. Zoom in to see smaller creeks. Use the layers button at the top right of the map to switch to streets or a satellite view.

All dates are on the events page. Updated every night.
Start with one thing
- Show up once. Pick one drop-in day close to home. No membership, no commitment.
- Show up again. The second time, people remember your name. This is the step most people skip.
- Get on the list. Join that group's newsletter, so you hear about the next one.
- Sit in on one meeting. Conservation districts and many groups meet in public. You can just listen.
- Offer one skill. After a few visits, once you know what they need.
Stopping at step two or three still counts.
Why going back matters
Trust takes time together. A University of Kansas researcher found it takes roughly 40 to 60 hours with someone to become casual friends, and 80 to 100 to become friends.[1]
He also found that working side by side counts for less than time spent just talking. His advice: if you work together, go to lunch.[1]
So pick one group and keep going back. Stay for coffee after the cleanup.
What to say the first time
- "Hi, I'm new. What can I help with?"
- Ask a regular how long they've been coming, and what they wish more people knew.
- Find out when the next one is before you leave.
Pick your way in
Four ways in. Open the one that fits.

Start with your streetFire safe and neighborhood groups

- No group on your street? The county's neighborhood programs help you start one with 15 to 20 homes, and can fund neighborhood projects.[15] How to start one
Join your watershed's groupNeighbors caring for one creek

No group where you live?
Many parts of the county don't have a watershed group, or had one that went quiet.
OAEC's free guide, Basins of Relations, walks through starting one.[18] The Map Your Neighborhood program is a smaller first step: 15 to 20 homes on one street.[15]
Or start by asking your conservation district. They know who's working on your creek.
We check every group on this page once a week. Something out of date, or a group we missed? Tell us.
