Project Description

Green Valley Consulting Engineers worked in conjunction with a team of specialized geotechnical, hydraulic, structural, and electrical sub-consultants for the development of Segment 6 of the Foss Creek Pathway. This fully-lighted, 4.1-mile-long multi-use trail and bikeway which, when fully completed with all ten segments in place, will traverse the entire west side of the City. It will parallel the City’s Foss Creek and planned SMART Passenger Rail Service and reside within a former North Coast Railroad Authority (NCRA) right-of-way. The overall purpose of the trail is to connect residential neighborhoods with commercial, employment, and recreational areas.

Segment 6 is a hilly alignment which extends approximately two-thirds of a mile in length and varies between 8- or 10-feet in width. This particular segment joins West Grant Street, a main east-west thoroughfare, to a popular neighborhood skate park (Carson Warner). It is flanked by steep slopes for about half of its length and required the design of four-differently configured concrete retaining walls – based on existing ground and future trail profiles – for soil stabilization purposes. Finally, in order to span an existing drainage channel, the trail design incorporated a 10-foot wide, 120-foot-long pedestrian truss bridge with a two-foot-thick concrete decking supported by cast-in-place piers. It was given a decorative weathered steel finish with a deck height set to the required FEMA clearance for the 100-year flood, via site specific hydraulic calculations. Additional design elements included the construction of earthen swales and rock swales, the installation of decorative lighting fixtures and electrical conduit/wiring, existing stormwater system modifications, and trail signage.

Clients Say

For over 20 years, Windsor Road remained an “incomplete street”. Windsor High students were forced into and across the heavily-trafficked road to reach school. GVCE filled the gaps, creating safety, convenience, and comfort... The traffic improvements made by the Town of Windsor in front of Windsor High has provided families with more drop-off/pick-up convenience in front of the school... We only hear praise from families and students for all of the road improvements! Marc Elin, WHS Principal
