The $160 million casino is the largest of the seven Osage Casinos and is billed as the Nation’s flagship casino, which brings in the most revenue to fund Osage Nation government services and their casino operations. The project is a 247,000 square foot casino, 75,000 square foot hotel and associated parking garage.

Wallace  provided civil engineering services for the casino, hotel and parking structure on this 100-acre site with a mile of stream relocation. The casino has 68,000 square feet of gaming space with 16 table games, five poker tables, 1,500 electronic gaming machines, a sports bar and grill, a small cafe and full service brew pub. The hotel includes 141 guest rooms, six suites, a fitness center and resort style pool with a 6,000 square foot outdoor entertainment space. The hotel also houses a 10,000 square foot ballroom and three breakout rooms for conference and conventions, and a 45,000 square foot event space. The new four-level parking garage adds 1,039 spaces bringing the total number of spaces, both surface and structured parking, to 3,381.

In order to facilitate the construction of the new Osage Casino building, the existing stormwater channel that ran through the site had to be rerouted around the new building footprint. This resulted in 4,735 feet of relocated channel, including two large culverts. The channel dead ends into a detention pond, which was designed to accommodate the 200+ acre drainage area with over 13 acre-feet of volume. Additionally, there were existing wetlands located within the proposed area of development. Portions of the existing wetlands were required to be mitigated and relocated with the remaining wetland areas being preserved.
