When it rains, street drains help to keep Sammamish neighborhoods from flooding. If leaves pile up and block these drains, water can back up and cause ponding that slows or stops traffic and can even flood yards and homes.
Our drainage crews and contractors work hard to maintain all of Sammamish’s drainage infrastructure, including storm drains on streets. But with thousands of drains spread all across the city, so we need your help too. You can help prevent flooding by paying attention to what’s happening with the drains on your block. A few small maintenance actions on your property can also prevent stormwater from ponding.
