What Sammamish's numbers say about water damage
Sammamish is one of the most established suburbs tracked here — 66,110 people (2025 estimate), down just 2.0% since 2020[3]. The city spans 20.4 square miles at 3,236 residents per square mile (the 13th densest) and sits entirely in King County, served by ZIP codes 98075, 98074[4].
Sammamish mixes 13% of homes built since 2010 and 13% before 1980[2]: new supply lines and water heaters in one house, aging pipe and original valves in the next — so where a leak starts depends a lot on the address.
