    Segment 3B Waterline Wilsonville, Oregon, This project involved installation of a approximately 2,500 lineal feet of new 48" welded steel waterline through a sensitive area near the Boeckman Creek Slough and Wetland. The new waterline is an extension of the existing 48" waterline installed by Kerr Contractors in 2002. Work areas were limited and trench conditions required extensive dewatering during pipe installation. Erosion control and protection of the sensitive work areas and the surrounding wetland areas was a project priority.

    Linden Ranch Wind Farm Gilliam County, Oregon, Although Crestline was not the primary civil contractor on this 50 megawatt wind energy project, we worked with enXco to construct several project components that were outside of the prime contractor’s scope of work. Work included building the primary access road to the site, road surfacing, mass grading for the substation and switch yard, upgrades to County roads as required for crane and truck travel, construction of a laydown yard for the concrete batchplant and foundation contractor, and most recently, we installed the fiber optic line from the Operations and Maintenance facility to the turbine string road.
