NOTABLE OMISSIONS: Jacobs, KPFF and Brown & Caldwell would have likely ranked high on The List but did not respond to the information request. ABOUT THE LIST: Information was obtained from firm representatives through questionnaires and could not be independently verified by the Portland Business Journal. In case of ties, companies are listed alphabetically. The Portland metro-area is defined as Clackamas, Multnomah and Washington counties in Oregon and Clark County, Washington.
