Help Reduce Localized Flooding

The City encourages residents to clear leaves and other debris from storm drains near their property. A quick sweep with a broom or rake will easily clear off a catch basin and keep our drainage systems flowing properly. Remember, never remove a storm drain cover or attempt to clean a drain located in a busy street.

Put leaves and other yard debris in your yard waste bins for easy removal and recycling. Do not put leaves onto the street.
