Ten Trails & Black Diamond WA — Buyer's Guide 2026
Ten Trails / Black Diamond WA King County (NEW OLH silo — completes John Burns top-100 national MPC list at rank #100; extends OLH WA coverage alongside Snoqualmie/Sammamish King County silo and Tehaleh Pierce County silo): YarrowBay developer; King County southeastern growth corridor; John Burns #100 nationally — final entry on the list. Black Diamond: former coal-mining town; distinct small-town historic character within King County growth corridor. Extensive trail network (community name origin) connecting forested areas, wetlands, community parks in Mount Rainier foothills. Regency at Ten Trails: 55+ active adult section, Toll Brothers Regency national brand, age-restricted SFH, resort-style amenities, smaller/more intimate scale than Trilogy at Tehaleh (Bonney Lake/Pierce County comparison). Access via SR-169 and SR-516. Commute to Seattle/Eastside (Bellevue/Redmond/Kirkland): 45-70+ min peak hours — longer than closer-in King County suburbs Renton/Kent/Auburn; best for remote/hybrid workers or Covington/Maple Valley/Auburn corridor employment. King County tax/school structure continuity vs Pierce County (Tehaleh) — relevant differentiator for buyers relocating within King County specifically. Washington: no state income tax.

Regency at Ten Trails — The 55+ Anchor
Regency at Ten Trails brings Toll Brothers' nationally recognized Regency active-adult brand to Black Diamond — age-restricted single-family homes with resort-style amenities integrated into the broader Ten Trails trail network and natural setting. Compared to the larger Trilogy at Tehaleh in nearby Bonney Lake, Regency at Ten Trails offers a smaller-scale, more intimate 55+ community experience while remaining within the same general South King/North Pierce County geography that has become a primary destination for Puget Sound retirees seeking value and natural beauty.
Black Diamond's Trail Network and Mount Rainier Setting
Ten Trails takes its name from the extensive trail network woven throughout the master plan — connecting forested areas, wetlands, and community parks in the foothills below Mount Rainier. This natural infrastructure, combined with Black Diamond's small-town historic character (the area's identity is rooted in its coal-mining past), gives Ten Trails a distinct community feel compared to more conventionally suburban King County developments. For buyers seeking genuine forest and mountain views without leaving King County entirely, Ten Trails delivers a combination that's increasingly rare closer to Seattle's core.
The Honest Commute Conversation
Black Diamond's position in King County's southeastern corner, accessed via SR-169 and SR-516, means a genuine commute distance from Seattle's core and the Eastside tech corridor (Bellevue, Redmond, Kirkland) — typically 45-70+ minutes at peak hours, longer than from closer-in King County suburbs like Renton, Kent, or Auburn. Ten Trails works best for buyers with remote or hybrid work flexibility, employment in the Covington/Maple Valley/Auburn corridor, or those making a deliberate trade-off of commute time for space, price, and the natural mountain-foothills setting.
