Twin Lakes Square is a Master Plan community of diverse developments in the fast-growing city of Marysville. Located adjacent to the Gissberg Twin Lakes park and recreation area, the project will provide for the needs of the area employment base, support the quality of life of local workforce and their families, and provide attractive community homes, shopping and amenities.

Synergy worked with ownership to develop a Master Plan for the project with the local jurisdiction. The project comprises three phases. Synergy performed grading work and utility extensions to allow for construction of 337 single family homes for Phase I across 30+ acres. Phase II will consist of 144 garden-style apartment units, along with 12,000 square feet of retail. Phase III will consist of 168 garden-style apartments, 12,000 square feet of retail, and a 120-room hotel.


Rainier Landing is a transit-oriented master-planned community located in the heart of SeaTac’s Angle Lake District. Redeveloped from a 6-acre light industrial site, the project reimagines underutilized land into a vibrant, high-density residential destination just steps from the Angle Lake Light Rail Station. Designed with long-term market alignment in mind, the community balances urban accessibility with elevated residential living.
