Neighborhood Guide · Black Diamond, WA
Black Diamond: history today, big plans tomorrow.
A small town with a coal-mining past and one of the region's largest planned communities rising around it. Black Diamond offers new-construction value at a more measured pace than its neighbors.
What Black Diamond is like
A 19th-century main street with a 21st-century growth plan.
Black Diamond traces its roots to 1880, when coal was discovered near Jones Lake and the town that grew around the mines became a bustling company town, peaking at about 3,500 residents in 1885. The mines closed in 1958, but Railroad Avenue's historic storefronts still give the town its character.
The modern story is growth. Master-planned communities like Ten Trails are adding thousands of new homes, along with the retail and schools that come with them, and the town is one of the most affordable gateways into newer construction in South King County.
Schools are split between the Enumclaw and Tahoma districts depending on the address, so we always confirm the catchment for a specific home. The commute runs about 42 to 51 minutes to Seattle on SR-169, the designated commuter corridor.
