Kern River Forebay

Client: Southern California Edison

Location: Kern river

WestLAND Group received an emergency work order request from Southern California Edison which required immediate attention. WestLAND provided survey, engineering and mapping support to the SCE engineering team that was performing emergency reconstruction design, slope and structure stabilization improvements and retrofits.

Tasked with performing an extensive survey of a 48” spillway pipe, pipe supports and appurtenances as well as a precise topographic survey of a hillside after a major storm event resulted in catastrophic slope failure and structural destruction caused by erosion and debris flow; damages included shut-down of SCE hydro-electric generating station and closure of State Highway 178.

Resource coordination began immediately, Project Manager and a field crew were deployed the following morning to assess the scope of work and site conditions.  Continuous long-day working environment for the duration of the project was scheduled in order to meet desired timelines. Services included a combination of aerial surveying, laser scanning, GPS and conventional topographic surveying to execute the survey and provide high quality mapping deliverables that included generating TIN surface, contours, pipeline alignment, plan and profile view layout.  Field crews marked horizontal stationing along pipeline which provided engineers key reference points and enabled them to quickly and accurately document areas that required pipeline and/or structural replacement.
