Permeable Pavement


​Permeable Pavement Study

A collaboration between IDEA High School, The City of Tacoma Center for Urban Waters, The Boeing Company and Washington State University. 

Due in part to a generous grant from Boeing and the US Department of Ecology, the City of Tacoma has partnered with IDEA to study the benefits of using permeable pavement as a means to filter out contaminants from storm water run offs. Five different permeable pavement compositions are being tested in IDEA's parking lot, with water sample test sites installed throughout to measure during the rainy season. The impact of daily commuting traffic of a high volume area such as this high school parking lot combined with the large field to install two bio swales as a control group will give researchers at WSU the opportunity to see which portion of concrete is the most effective at filtering out groundwater pollutants. Students at IDEA and Tacoma's Science and Math Institute are enrolled in a month-long mini-term class taught by SAMI instructor Matthew Londsale who has developed an environmental engineering curriculum around the project in partnership with Washington Green Schools. This curriculum will be piloted at IDEA during the month of January and then shared with other science instructors around the State of Washington. 

Check below for project updates, parking and bus impacts and a live video feed of the construction process throughout the month of january.

​​During the construction phase of the project, cars and busses will not be allowed in the construction area. This means that during the month of January, cars for students and staff will need to park on city streets on the West side of the building (off of South Park Avenue and adjacent city streets). Busses will drop off students in front of Park Avenue. Please see the map below and park in the green areas on the street. The red areas will be reserved for bus pickup and dropoff and construction zone. Please be curteous to all neighbors and do not block driveways.
