Built For The Future

The Trailside Group, known for offering decades of new home construction, design, land planning, and development experience, is proud to announce the next adventure – the new, master-planned community of Ederra.

Located in the rolling hills and mountains above Cle Elum & Roslyn, Washington, Ederra is just an hour east of the bustling King county job market.

This dynamic project will provide significant community public amenities and improvements while creating sustainable economic growth to Cle Elum and its residents. Better yet, Ederra is being developed by a long-time local Cle Elum business who holds the community’s values near and dear to their hearts. Ederra’s number one priority is enhancing the Cle Elum way of life.

Ederra was developed in collaboration with the community to address the needs and goals of residents, business owners, recreational users, the City of Cle Elum, service providers and Tribes, among others.

Construction at Ederra will be carefully phased over the next decade — beginning now, through 2036 — based on market demand. It’s part of the City of Cle Elum’s approval of a Development Agreement nearly 10 years ago, and its recent acceptance of the first application to implement the approved Master Site Plan at the property.

When complete, Ederra will include up to 962 residential units including diverse and creative neighborhoods with home products ranging from apartments, townhomes, cottages, duplexes, and detached single family homes, large and small. The development will also include at least 3 parks and various other outdoor-amenity spaces open to the public. A modest amount of neighborhood commercial buildings will be built, planned to serve the greater Cle Elum community and residents, but will not compete with the downtown core, which is so vital to our mutual success.
