If you are drawn to the idea of newer homes, shared amenities, and a neighborhood designed with trails and open space in mind, master-planned living in Black Diamond may be on your radar. At the same time, it helps to know that this lifestyle usually comes with more structure, more shared responsibilities, and more association oversight than a typical subdivision. In this guide, you will get a clear look at what daily life can feel like, what ownership costs may include, and what questions to ask before you buy. Let’s dive in.
Master-planned living in Black Diamond
Black Diamond’s growth strategy is built around planned development that aims to preserve rural character while allowing future growth in an environmentally sensitive way. The city has said population projections may rise above 20,000 over the next 20 years, so planning is a major part of how growth is being managed.
The city identifies two master-planned developments, The Villages, better known as Ten Trails, and Lawson Hills. For most buyers today, Ten Trails is the most visible example of master-planned living in Black Diamond.
It is also important to know these communities are still evolving. Public notices from 2025 and 2026 show ongoing amendments and plats for Ten Trails and Lawson Hills, which suggests the governing documents, phasing, and details of future buildout are still active.
What the neighborhood is designed to deliver
Black Diamond’s master-planned development framework focuses on open space, connected streets, neighborhood centers, and linked trails. The city also says master-planned land should keep 50% of the total area as open space, which shapes the overall feel of these communities.
That planning approach often creates a more connected neighborhood layout than you may see in a standard subdivision. Instead of homes being the only focus, the design intent includes how you move through the area, where shared gathering spaces sit, and how outdoor areas connect.
In Ten Trails, that framework shows up as an amenity-forward lifestyle. The community highlights multiple parks, miles of trails, fire pits, bocce ball, pea patches, picnic areas, ping pong, a performance stage, and community events.
What day-to-day life may feel like
For many buyers, the biggest appeal of a master-planned community is convenience. The goal is not just to provide housing, but to create a setting where recreation, casual gathering, and some daily errands feel closer to home.
Ten Trails also markets a future retail village intended to bring shopping and dining closer to residents. As that kind of planning takes shape, your day-to-day experience may feel more neighborhood-centered than in a community where homes are built without shared destinations.
If you enjoy outdoor access, Black Diamond adds another layer to the lifestyle. King County describes Black Diamond Open Space as a 1,240-acre forested park with 17 miles of trails for activities like hiking, mountain biking, horseback riding, and nature observation.
For buyers comparing home styles, Ten Trails says its housing mix includes townhomes, duplexes, and detached homes. That variety can give you more options depending on your budget, space needs, and maintenance preferences.
Expect a formal HOA structure
One of the clearest differences in a master-planned community is the level of organization behind it. Ten Trails has a resident HOA portal and an on-site association manager, so you should expect a formal community-level association structure rather than a simple neighborhood setup.
That usually means you will have defined rules, dues, and procedures for questions about covenants and community operations. In practical terms, there is more structure in exchange for shared amenities and coordinated maintenance.
City ordinance records also reference both the Ten Trails Community Council and the Ten Trails Residential Owners Association. That points to a layered association setup that may affect how rules, maintenance, and responsibilities are handled across the community.
What ownership costs may include
Many buyers think HOA dues only cover landscaping or common-area upkeep. In a master-planned setting like Ten Trails, ownership costs may reach beyond that.
City ordinance records reference private storm drainage, irrigation, landscape lighting, and private sanitary sewer systems. That suggests some of your dues or community costs may support privately maintained infrastructure, not just visible amenities.
Ten Trails also states that true 1-gig internet is available in every home and included in the quarterly community HOA dues. That can be a meaningful convenience, but it is also a reminder that dues may bundle services you would otherwise arrange separately.
Because ownership costs can reflect infrastructure, services, and amenities, it is wise to look past the headline dues number. You will want to understand what is actually covered and whether any separate neighborhood or sub-association fees apply.
Design rules are part of the package
Master-planned living often comes with a consistent visual character, and that does not happen by accident. Black Diamond’s framework describes a design intent that includes varied building profiles, front porches, traditional materials, reduced garage emphasis, and limits on building massing and height.
The city also notes that project-specific design standards are incorporated into development agreements. That means the rules for a specific community may go beyond the city’s broader framework.
For homeowners, this can be a positive if you value a cohesive streetscape and long-term design consistency. Still, it can also mean less exterior freedom than you might have in a neighborhood without architectural review.
The city’s staff reports note that HOA CC&Rs or an architectural review committee may review green technologies such as solar panels, though they should not preclude them. If exterior changes matter to you, it is worth reviewing those guidelines early.
Why due diligence matters more here
Because Black Diamond’s master-planned communities continue to move through amendments and phased review, buyers should avoid relying on an older brochure alone. Community features, maintenance responsibilities, and governing documents can shift over time.
This is especially true in a phased development, where rules and obligations may vary by plat or sub-association. What applies to one section of a community may not match another section exactly.
Before you buy, review the current CC&Rs, HOA or ROA budgets, architectural rules, amenity schedules, and maintenance responsibilities. Those details can tell you a lot about your monthly costs, your flexibility as an owner, and how the community operates in real life.
Is master-planned living right for you?
For the right buyer, master-planned living in Black Diamond can offer a strong mix of newer housing, shared amenities, connected trails, and a neighborhood feel shaped by intentional design. If you like the idea of parks, events, open space, and a more organized community setup, it may be a great fit.
If you prefer fewer rules, lower association involvement, or more freedom with exterior changes, you may want to compare master-planned options with other neighborhoods nearby. The tradeoff is usually straightforward: more shared benefits often come with more oversight.
The best choice comes down to how you want to live day to day. When you understand the rules, costs, and design intent upfront, you can decide with much more confidence.
