Mt Si High School


Snoqualmie Valley School District passed a 244 million bond for this new school in 2015. Construction began in 2017 and will be completed in 2021. The School is designed for 2,300 students serving grade 9 thru 12 and is 253,000 square feet in size. Unique features about the school include:

  • That it is built in a flood plain and to overcome this the entire school is elevated with parking below.
  • The soil that the school is built on is poor so stone columns where bored into the ground to provide a suitable foundation.
