The Sammamish Commons project encompasses the development of approximately 30 acres of land.

Ten of these acres are referenced as the “upper site”. Development on the “upper site” will include the city hall, parking, active recreation areas, and open areas. Parking will be accommodated both below the civic center structure and at ground level. A civic plaza is proposed adjacent to the new building for use by the public. A small pergola will be incorporated into the plaza area for public use. The upper site will also include a youth activity area with sport court, skate park, and climbing wall.

The remaining 20 acres are referenced as the “lower site”. Development of the lower site will be primarily for passive use. The existing wetlands and buffers will be preserved. Structures proposed for the park include three picnic shelters, a viewing tower, and a play ground. In addition, an informal play field will be developed in the northwestern corner of the site. The remainder of the site will be maintained in undeveloped grass land. In addition, planting includes a Northwest garden and orchard, large lawn areas, and mixed grass areas that will be similar to the existing pasture grasses at the site.
