A master plan is a conceptual design that is used as a guiding document for implementing future improvements at a park. A master plan is a multi-step process that receives input and direction from the public, City Council, and Parks & Recreation Commission. During the early stages of this process, long-term goals and objectives will be established to guide the development of design alternatives. Once design alternatives have been refined in to a final conceptual design, the next step is to determine a phasing and implementation schedule, based on recommended priorities from the public, City Council, and Parks & Recreation Commission. It is important to note that a master plan is conceptual and continues to be refined during the design phase, which can take several years to implement.

Project Overview:

Beaton Hill Park and Big Rock Park South are centrally located within the City’s core. The City acquired Beaton Hill Park in fall 2018. Since then, the only work done at this site has been the demolition of the family residence and accessory structures. Beaton Hill Park is located directly north of the three Big Rock Park properties (North, Central, and South) and is currently closed to the public. Big Rock Park South was transferred to the City in November 2021 and is the final property of a phased land donation agreement.

Prior to commencing extensive development or improvement on City parkland, a master plan is completed by following the City adopted master plan process. The intent in following this process is to look at the parkland in a comprehensive manner, utilizing a process that involves the entire community.  A goal of the consolidated master planning process for Beaton Hill Park and Big Rock Park South is to prepare plans that integrate with Big Rock Park North and Central for the purpose of providing a cohesive group of parks within the City’s core.


Beaton Hill Park is located approximately half a mile west of Sammamish City Hall in the heart of the City and just south of the future Town Center. The park is comprised of two parcels that were purchased by the City in fall 2018 in an effort to preserve open space in a rapidly densely developing area in the City; it is named for the family that owned the farmstead for over 80 years. The vacant land totals 9.36 acres and has mature trees, rolling topography, open meadows, three wetlands, and a seasonal stream. The City was awarded a King County Conservation Futures Grant as a reimbursement for approximately 4 acres of the site, which will be designated for permanent conservation. 


Big Rock Park South is the third and final property of a 51-acre phased land donation agreement located in the center of the City. The first two parcels, Big Rock Park North and Central, opened to the public in 2016 and 2021. The property was transferred to the City in November 2021. Like the conditions placed on the previous two parcels, this park will facilitate a variety of low impact active and passive activities that may include nature trails, open space, and passive sports meadows. There are a few existing structures on this parcel. Restrictions were put in place to preclude development of new structures exceeding 2,500 square feet to support the development of the park in a manner that preserves the site’s natural beauty. The 15 acres that make up this property include dense forest cover, meandering trails that navigate relatively unvarying topography, sensitive areas, open meadows, a single-family home, detached garages, and a barn.
