SUQUAMISH — Suquamish Clearwater Casino Resort is preparing for a major expansion.

The casino released on Thursday its five-year plan, which includes convention space, hotel rooms and more amenities in four phases. The project is scheduled to begin in June.

The first phase of the plan includes the addition of 10,000 square feet of meeting space and a 4,500-square-foot pre-function area. Also planned: A new restaurant, remodeling of the Longhouse Buffet, a two-story building for support services and offices, a walkway with elevator entrance to the casino from the resort, and 700-car parking garage. The first phase is expected to be completed by December 2014.

By May 2015, the plan calls for the addition of a 100-room, five-story hotel. All rooms will have a water view. The building will be structured to add an additional three stories in the future.

A remodeling and expansion of the casino is planned to be complete by the end of 2016. It is a 5,700-square-foot expansion, which includes a 350-seat lounge, specialty restaurant and new bar. There will be a relocation of the cage, security and Club Clearwater.

The last phase, to be complete by December 2017, will add 15,000 square feet of meeting and entertainment space, with moveable walls that divide space into five rooms. A 11,500 square-foot of pre-function and 8,500 square feet of support space will be added.

All facilities are planned to remain open during construction, unless otherwise publicized.

Rice Fergus Miller will lead the remodel. The contractor and project manager have not been disclosed.

The casino’s last remodel included the addition of the resort and spa in 2006.
