Kane Drive Roadway Widening

PBS, as part of a larger project team, was selected by the City of Gresham Public Works to provide engineering, environmental, and natural resource services for the Kane Drive widening project. Tasks performed by PBS include permitting, storm water facility design, Phase I Environmental Assessment, wetland delineation, geotechnical analysis, and tree protection plan.

PBS scientists worked closely with KGA structural engineers to develop alternatives to widen the road at the existing Kelly Creek crossing to avoid impacts to the stream and fish. These scientists also discussed the project and design alternatives with agency staff to determine whether actions were required to address a potential barrier to fish passage at the existing culvert. PBS engineers worked with City staff to identify stormwater treatment options and facility locations. City staff designed the conveyance systems, and PBS engineers designed rain gardens and pervious pavement. PBS’ certified arborist examined trees to be removed by the project and those along the edge of the proposed right-of-way. Following the on-site examination, our arborist prepared a tree protection plan.

PBS also provided geotechnical analysis at the creek crossing and proposed retaining walls and preparation of permit applications.
