About the Area
Living in Black Diamond
Black Diamond is one of King County's hidden gems — a small coal-mining-era community now transforming with a large master-planned community bringing new homes, parks, and commercial amenities to the rural landscape. The historic downtown retains its original brick character, and the surrounding land is a mix of state forest, trails, and open space. Buyers looking for affordable, newer construction with a country setting will find Black Diamond compelling.
Highlights
- Historic coal-mining heritage with preserved brick downtown and museum
- Black Diamond master-planned development bringing new homes and parks
- King County Forest and Coal Creek Trail system for hiking and mountain biking
- More affordable new construction than comparable communities further north
- SR-169 access connecting north to Maple Valley, Renton, and I-405
