American Society of Landscape Architects. Pacific Northwest Chapter.

The Pacific Northwest Chapter of the American Society of Landscape Architects (ASLA) was founded by eleven landscape architects on October 17, 1959 to serve Oregon, Washington, Idaho, Montana, Alaska and the province of British Columbia.

Chapter officers were drawn from throughout the region and a two- or three-day chapter meeting was held annually. In 1961, the Washington and Oregon sections of the chapter were authorized. Eventually, Montana-Idaho and Alaska sections were added. In 1971, the Pacific Northwest Chapter hosted the ASLA Annual Meeting in Portland, Oregon. In 1973, the Pacific Northwest Chapter of ASLA was divided into the chapters of Washington, Oregon, and Montana-Idaho. The fourth section, Alaska, became a chapter in 1976.
