Mountainview High School, Auburn

RoseWater GHD provided plans and design of drainage, grading, paving, utilities, and temporary erosion and sediment control (TESC); and construction observation and support for a new
193,000 square feet high school in Auburn, Washington.

The development on the 40-acre site consists of buildings, paved pedestrian areas, parking lots (providing a total of 650 spaces), a bus drop-off area, four ball fields, a soccer/football track and field, and seven tennis courts.

GHD provided roadway/right-of-way design to improve sight distances for 1100 feet on 132nd Avenue SE and 900 feet on 124th Avenue SE, and redesigned  a series of intersections.

GHD designed TESC plans that allowed the contractor schedule flexibility and cost savings, while also enabling the use of innovative/newer technologies that were considered leading edge by King County.  Because of the site’s steep slopes and large building areas, GHD designed retaining wall systems to minimise the grading impacts to site soils. This design decreased site disturbance and provided a more environmentally-sensitive plan. 

At the owner’s request GHD developed erosion control plans that exceeded the standard County requirements for sizing water quality treatment ponds and for site erosion control measures.  These measures minimised the amount of sediment generated onsite due to construction activities.  In addition, GHD coordinated the design permit process with the County.
