Big Rock Park opened to the public in October 2011. It represents the first phase of a large land donation from Mary Pigott, to the City of Sammamish. This donation will ultimately result in over 51 acres of new park land. The new park boasts many exciting features including trails, extensive wetlands, ponds, mature evergreen and deciduous trees and a massive boulder. While you're at the park you may catch a glimpse of the abundant wildlife; ducks, woodpeckers, owls, frogs, blue herons and beaver.

Site A is the portion of the park that was opened to the public in October 2011. It fronts SE 8th Street and is a total of 15.9 acres. This property includes a 3,460 sf house, wetlands, pastures and over a mile of wooded trails. This parcel was donated in 2011 with an extensive trail system already in place. A large volunteer work party prepared the site for the opening by clearing brush back off the trails, surfacing the trails, installing privacy plantings and repairing fences and boardwalk. City Staff installed a new kiosk and pedestrian gate for access. Currently, parking is available for park users along SE 8th Street.

Site B will be transferred to the City over the next five years. This parcel totals 20.41 acres of variable terrain. Site B adjoins Site A at the south east property corner and contains a series of wetlands and ponds, wooded trails and pasture land. It is fully fenced and also has a residence and several out buildings.

Site C
is currently a private residence and is planned to be donated in the future; however, the timeline is currently unknown.

Park Master Plan:

The preferred alternative for the Big Rock Park Master Plan was developed after more than two years of public process, plan development and refinement. The final plan, adopted at the July 8, 2014 City Council meeting, highlights the natural beauty of the park while expanding opportunities for passive recreation and environmental and heritage education.

Reard-Freed House with a new roof, siding and paint.

The Reard-Freed House is a historic farmhouse owned by the City of Sammamish.

The house was moved to Site B in 2012.  Renovations to date include adding a new roof, siding, and paint. New windows and doors have been installed by the Sammamish Heritage Society.

For more information about the Reard-Freed House, visit the Sammamish Heritage Society’s website.

Coming soon.

In partnership with the Lake Washington School Districts Tesla STEM High School, the city has teamed up with 10 students to design and build a community project at Big Rock Park as part of Phase I development. Their challenge is to create an environmental education program, restore and enhance a riparian zone, promote renewable technology and design interpretive signage. The internship started in early February and will run through June with one week planned for project installation in early October.

Environmental Education
The Environment Education Team is tasked with developing an online curriculum “tool kit” to be used in the classroom and at Big Rock Park to teach how earth materials such as soil, water and gases shape and effect our ecosystems. Each tool kit will include a project description, outline, learning objectives, material list, instructional video, worksheets and online resources such as National Geographic’s Fieldscope to share observations and collected data.

The STEM internship team is researching and developing age appropriate classroom activities that meet the Washington State Essential Academic Learning Requirements (EALRs) and focus on 4th/ 5th grade level Earth System Structures and Processes (ES2). Topics currently being developed include:

  • Understanding Turbidity and Assessing Riparian Health
  • Measuring Velocity and Monitoring Erosion
  • Soil Hydrology and Assessment
  • Plant and Soil Health
Riparian Zone Restoration

Solar Power and Electric Vehicle(EV) Charging Station
In the City of Sammamish and neighboring cities, there has been a rapid increase of electric vehicles on the roads. This emphasizes the growing need to have more EV stations placed. The Green Technology Team is working to acquire an EV station and locate it within the new parking lot currently being designed as part of phase I development.

In order to promote sustainability within Sammamish, the team is researching and working to procure two solar panels to be installed on the existing park kiosk. The team believes there is a flawed perception in the Pacific Northwest that solar is extremely expensive, isn’t practical in a cloudy, rainy environment and has a long payback time. The implementation of solar panels on this kiosk will prove that solar is applicable and functions in our climate. Additionally, there will be a live monitoring system connected to the solar panels that will be presented through a database available to the public. This enables the public to understand how the energy the solar panel produces and translates that into the amount of carbon dioxide saved from emission.

Interpretive Signage

The Interpretive Design Team is tasked with creating park signage that provides educational content describing the value of riparian zones and the basics of solar power. Both interpretive signs will include three levels of detail, targeting those who want to stop briefly and for those who want to linger and peruse the content.

These signs will be resistant to weather conditions, abrasion and vandalism. Overall, the signage will provide both aesthetic and education value to Big Rock Park and will be a great component to educate the community about importance of restoring critical areas and renewable energy.
