The Stadium Authority announced Thursday that it is beginning the Environmental Impact Statement (EIS) and master planning process for a replacement for Aloha Stadium. It made the announcement while introducing Crawford Architects as its master planning and environmental review consultant as well as releasing that firm’s Alternative Site Analysis.

Based in Kansas City, Mo., Crawford Architects has four branch offices in California and Washington and one in Australia.

“We’re proud to have such a high caliber consultant like Crawford Architects leading our master planning and EIS process,” said Ross Yamasaki, chair of the Stadium Authority, in a statement. “They’re one of the best in the business having had a hand in some of the most high-profile stadium projects and mixed-use developments in the country including work for the Minnesota Vikings, the Green Bay Packers’ Lambeau Field, and Seattle Seahawks’ CenturyLink Field.”

The Alternative Site Analysis examined six sites on Oahu as potential locations for Aloha Stadium’s replacement, including the existing Halawa site plus the University of Hawaii at Manoa, UH West Oahu, the Ala Wai Golf Course, Kapiolani Park and the airfield at Kalaeloa. The Halawa site came out on top based on such criteria as potential development costs, economic impact and the availability of infrastructure.
