Enjoy watershed activities with Kids In Parks to learn more about erosion. Volunteers should wear long sleeves, pants, and sturdy closed-toed shoes.  Light snacks will be provided, and items will be raffled off to those who volunteer. Registration is limited, so please contact joe.grey@sfgov.org now to reserve your spot.
