Lake Hills Connector, Bellevue, WA

Puget Sound Energy

White Shield performed a detailed route survey for the Bellevue Lake Hills Connector High Pressure (HP) gas line project for Puget Sound Energy (PSE). This project is supporting the design of approximately 10,000 linear feet of 16” HP main and 8,500 linear feet of 12” HP main in the Kelsey Creek area of Bellevue. The route began near the intersection of SE 8th and 118 Ave SE, and continued to NE 10th St and 110th Ave NE. This project required a complete route and topographic survey presented with 1-foot contours. White Shield provided PSE monuments and benchmarks, property boundaries with tax ID numbers, easement boundaries, and the edge and centerline of ROW. Also mapped were above ground and below ground utilities, driveways, gutters, fences and gates, the 100-year flood plain and the ordinary high water level of Kelsey Creek. Services also included mapping ditch lines, manholes, catch basins, roadway striping and other pavement markings, traffic signals, curbing, and sidewalks. White Shield performed a detailed wetland survey of the route and identified the specific aquatic and riparian vegetation types within those areas.
