The Olympia Woodland Trail system is challenged by steep terrain and sensitive environmental areas, including a crossing of Moxlie Creek. A comprehensive study and predesign of trail segments from the Tumwater Historical Park to the Chehalis Western Trail connection were evaluated and documented in a feasibility study. The study explored various routes including structural and environmental considerations to make a connection from the Tumwater Historical Park to Henderson Boulevard that involved traversing along steep embankments, bridging over critical water bodies, crossing rail lines, and addressing other significant design elements.
SCJ prepared concept-level design of two alignments using existing Lidar data and field-collected GPS data. SCJ prepared a report recommending a preferred alignment that results in the best value considering ADA access, practical use of existing walking paths, and avoidance of sensitive environmental areas. Some portions of the trail will use boardwalk on pin-piles to minimize/avoid impacts to wetland and stream areas. This study has led to the implementation of several trail segments (project phases) with just a few of the phases remaining to complete the final links. SCJ worked with Parks, Arts & Recreation staff to develop a feasibility approach tailored to match available funds.
“I love the challenge of designing a trail with such a variety of elements from rail crossings to bridges to steep banks. And, as a cyclist myself, I’m hoping to use this trail in the future to ride to a redeveloped Old Brewery and have a coffee.“
