Project Overview


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.

Components of a Master Plan:

A twelve to eighteen-month effort is anticipated for the master plan process which will include public involvement, with participation from the community at large, City staff, Parks & Recreation Commission, City Council, and community stakeholders. The intent of a consolidated approach for the master plans is to undergo a collective kick-off and public engagement effort to facilitate community introductions and discussions, as well as a collective department and city review. That said, individual master plan reports will be prepared for each park. The master plan process will consist of three phases as described below:


Evaluate existing site conditions, identify sensitive areas, complete site studies, and develop an overall understanding of the site. During this initial phase, a community survey will be prepared to assist with the development of initial park concepts.


The first public meeting will be held to present site analysis and provide the community an opportunity to share their hopes, dreams and concerns for the park. Following the first public meeting, a community survey will be published. Based upon the results of site analysis, community survey, City staff input, technical input and initial public input, a preliminary park design program will be developed that details proposed uses, design character and criteria.


The remaining public engagement will take place during the third phase of the master plan process. Two to three Master Plan alternatives will be prepared for each park, based upon the approved design program. This will include a narrative that summarizes the existing conditions, design alternatives, cost implications and regulatory criteria, and identifies issues which will require further study at the next stage of project development.

Based upon feedback from the community, Parks & Recreation Commission, and City Council, the
alternatives will be revised in to one preferred Master Plan alternative with a cost estimate. The final deliverable will be a Master Plan Report for each park, with final project drawings and narrative, project process, project phasing scenarios and phase costs.
