    Help Reduce Localized Flooding

    To help reduce localized flooding and help keep storm drains flowing at peak performance, 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.
