Sound to Olympics (STO) Sakai Pond Connector Trail

Project Overview

This next segment of the Sound to Olympics Trail is an extension of the existing shared-use trail from the SR305/Winslow Way intersection. The trail segment will pick up at the northeast corner of the High School Road-Highway 305 intersection, with the path running parallel to the highway for about 400 feet and then making a turn west toward Sakai Park. The path will be paved and 10 feet wide and eventually transition down to a 6-foot-wide gravel segment to connect to the Bainbridge Island Metropolitan Park District trails in the park.

The alignment for the trail was carefully planned to minimize removal of large trees. To compensate for the removal of 32 trees over an 8-inch diameter, we will plant 192 native trees and 180 native shrubs. Stormwater drainage will be low-impact designed infiltration into existing native soils, maintaining the natural functions within the corridor. The trail will provide an important accessible connection from the High School Road commercial area through Sakai Park, up to Madison Ave, Ordway, Commodore, and the High School.

Project Timeline

The contractor, Liden Land Development, began construction in early June 2021 and should be finished by November 2021.

The contractor has completed staking the alignment, rough grading, installation of most of the drainage system, and is completing the subgrade preparation for the trail surfacing.  See above photo showing the alignment from the High School Rd/305 sidewalk.

Week of July 5
This week the contractor, Liden Land Development and Excavation, continued work setting up sedimentation control fencing and clearing vegetation within the trail alignment area. Next week, they will install a temporary rock construction apron to allow trucks to access the site from the SR305 highway, and begin grading work to install culverts and drainage pipe that will cross under the new trail. Please continue to use extra caution traveling south on the highway approaching High School Road.

What is the STO?

The Sound to Olympics Trail (STO for short) is a regional trail crossing Kitsap County. It will connect the trails of the Mountains to Sound Greenway - across Puget Sound - via both the Bainbridge and Kingston ferries - with the Olympic Discovery Trail beyond the Hood Canal Bridge.

The STO is intended to be a family- friendly facility, and one that provides more room for people with disabilities. Walkers, cyclists preferring a more leisurely pace, and people using strollers, wheelchairs, and mobility aid devices will benefit from this paved, shared-use path.

This City’s Capital Improvement Plan includes $269K (including staff project management costs) for this project.  Approximately $155K was contributed to the City via a developer contribution associated with the property on the northeast side of the SR305 and High School Road intersection.


The Bainbridge Island Parks Foundation brought in a 100-goat herd from Vashon Island and set up on the site of the trail from May 12 thru 18. 

The goats provided cute and eco-friendly vegetation removal before trail construction begins.
