Leaves and debris can cause localized flooding if they cover storm drains in the street. Blowing or sweeping fallen leaves into the street makes them a safety and stormwater hazard to your property and your neighborhood. The storm drains in your street catch, move, and release rainwater into the nearest stream to keep excess water away from your property.

Winter tips for keeping storm drains clear
During snowy weather, storm drains need your help to function as they're supposed to. Leaving them covered with snow means there's no place for rain and melting snow to go, so it might pool up or causeflooding.
Do not block storm drains with snow shoveled from your driveway.
If the storm drain is blocked, use a shovel to clear the top of the grate, and break up and remove any built up ice.
NEVER remove a storm drain lid or attempt to clean a drain located in a busy street.
Do not wade into water when you are unsure of the depth.
