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.
City Hall will be constructed on three levels:
- Garage (20,865 s.f.): Consists of 53 parking stalls, Generator, archives, mechanical and electrical rooms;
- First Floor (25,914 s.f.): Consists of city offices, Police Department, council chambers / emergency operations center and areas for public use;
- Second Floor (13,603 s.f.): Consists of future office space and mechanical well. The interiors of the future office spaces will not be finished in this contract;
- The cost estimate for the project is $12.8 million for the upper site work (city hall, civic plaza and youth recreation area) and $2.7 for the remainder of the park development. Extensive water & sewer work is included in the estimate. Due to recent increases in construction materials we are looking at adding 15% to this for current market conditions;
- Project is designed to comply with a Certification Level according to the U.S. Green Building Council's Leadership in Energy & Environmental Design (LEED) Rating System.
