Sammamish Valley Park is located on the corner of NE 116th Street and Willows Road, approximately 0.25 miles west of the Sammamish River, the Sammamish River Trail and King County's Sixty Acres Park. The 32 acre park was formerly used for agricultural purposes. It is currently vacant, relatively flat and contains wetlands. It is adjacent to other agricultural uses, a golf course, and commercial development. The property is also close to a developing residential neighborhood to the east.

A master plan was developed in order to plan for the future development of the park, including projected cost estimates, so the City can identify funding sources for the eventual construction. The following is a brief explanation of the park planning and development process:

Phase I: Master Plan Park--develop concept for the park
Phase II: Design Park--prepare detailed design and construction drawings
Phase III: Park Construction--bid and construct the park
