The stormwater system in Bellevue is a combination of streams, lakes, wetlands, pipes, catch basins and flood control sites – private and public systems that eventually drain into either Lake Washington or Lake Sammamish. Bellevue Utilities:
- Provides flood control;
- Protects water quality;
- Provides the safe conveyance of stormwater to streams, lakes and wetlands;
- Protects natural habitat; and
- Provides education to protect the environment.
Managing stormwater effectively involves cooperative efforts from both the private and public sectors. There are many things you can do to protect water quality.
Road Ponding and Localized Flooding
During heavy rain, water can collect on streets, sidewalks and low-lying areas. This is called road ponding or localized flooding. It can happen when storm drains become blocked by leaves and debris or when heavy rainfall overwhelms the drainage system.
What to do if you encounter flooding
- Avoid flooded roads. Never drive, walk or bike through standing or moving water. Water may be deeper than it appears.
- Turn around, don't drown. If you encounter a flooded road, find another route.
- Keep storm drains clear. If it is safe, remove leaves and debris from storm drain grates near your home. Never enter standing water or attempt to remove a drain cover.
- Report flooding. Call Bellevue Utilities at 425-452-7840 to report drainage problems or flooding that threatens homes or businesses. This number is available 24 hours a day for emergencies.
- Call 911 if there is an immediate threat to life or safety.
