Issaquah High School Goes Green

Issaquah, WA

The new Issaquah High School building includes two and three story sections and provides 285,500 square feet of academic, athletic and performing arts space on a 54 acre site. The courtyard has 20,000 square feet of pervious concrete on two levels with a unique joint design transferring down the levels. The project was executed in a continuous construction process and was phased in order to keep all students on site throughout the construction of the new facility. Issaquah High School is designed to serve an enrollment of 1,850 students and will have 85 teaching stations.

This project was designed with the goal of minimizing underground storage through the use of low impact bio-retention (rain gardens and pervious paving) to take advantage of infiltrative site soils. Even though it was not exactly calculated we have found infiltration strategies to be SIGNIFICANTLY more cost effective. Issaquah High School is compliant with Washington Sustainable Schools Protocol (WSSP).
