Keep Storm Drains Clear

Help Prevent Localized Flooding

Leaves and debris can cause localized flooding if they are allowed to cover storm drains in the street. Many residents mistakenly blow or sweep their fallen leaves into the street, not realizing they become a safety and stormwater hazard to their property and neighborhood. The storm drains in your street capture, move, and release rain water into the nearest stream to keep excess water away from your property.

How Can You Help?

  • Check to make sure storm drains in your neighborhood are clear of debris before major storm events
  • Rake fallen leaves into your yard waste bin
  • Use leaves as mulch on garden beds and landscaped areas
  • Join the Adopt-A-Drain program
  • Please make sure any landscaping companies hired by your Home Owners Association also refrain from blowing leaves into the street.
