Bon Tempe Lake HDPE Pipeline Installation, Marin County, California
Fugro provided multibeam hydrographic survey services to establish the alignment of a 3,500 foot HDPE pipeline in Bon Tempe Lake. Hydrographic survey information, engineering design data, and as-built survey data were combined to determine the location of an ancient river channel in the lake bottom relative to the pipeline alignment. The project was conducted utilizing conventional survey methods, work boats and commercial divers.
