About a month ago (Jan. 20) I wrote a story in the DJC on the green roof at the Gates Foundation’s garage. At 60,000 square feet or about 1.4 acres, it is the largest green roof in Seattle by a landslide.
The garage is a crosswalk away from Seattle Center on the east side of Fifth Avenue North. It is located next to the future Gates Foundation headquarters and is kitty-corner from EMP. The garage is technically a public-private partnership between the Gates Foundation and the city of Seattle. NBBJ was the architect. Sellen Construction was general contractor. Gustafson Guthrie Nichol was landscape architect.
The roof itself is visible from the Space Needle, a consideration in its design. The roof has five inches of soil over a layer of synthetic drainage.
