Join volunteers across the city to maintain storm drains, a critical part of our utility infrastructure.
Sign up to adopt a storm drain near your home or work. By registering, you commit to keeping the drain surface clear of leaves and other debris year round.
If you have any questions, please contact us at email@example.com or at (206) 233-7187.
