Growth & Planning

The City is on the verge of growth. At 4,200 citizens, population projections may reach above 20,000 in the next 20 years. Over the past several years, major annexations have increased the population and acreage of Black Diamond. The annexation of the Lake Sawyer area in 1998 doubled the number of citizens. Recent annexations in the City’s urban growth area have increased the City’s size by approximately 1,600 acres. Unlike other communities, the City has stood firm to its vision and growth strategies as identified with the community and captured in the Comprehensive Plan. As the final pieces fall into place, Black Diamond is in the position to allow growth to occur in a well-planned, environmentally sensitive manner that protects the rural character of our community.
