The Agua Caliente Band of Cahuilla Indians will pay Riverside County $125,000 this fiscal year for mental health care, gambling addiction and substance abuse as it moves forward with plans for a new casino in Cathedral City.

The casino is planned for a 13-acre lot at the northwest corner of East Palm Canyon Drive and Date Palm Drive. It would be the tribe's third casino. The others are in Palm Springs and Rancho Mirage.

Under terms in the agreement, future compensation will be determined once the planned casino opens. The first payment will be earmarked for the Riverside University Health System-Behavioral Health Department.

"The county agreement gets us another step closer to being able to realize this project in Cathedral City," tribal Chairman Jeff Grubbe said in an email. "There are still a few more steps, and we are looking forward to announcing a groundbreaking date in coming months."

The Riverside County Board of Supervisors voted 5-0 Tuesday to enter into the intergovernmental agreement with the tribe.

The deal also addresses environmental impacts and other areas that could affect quality of life in the county. It spells out how either party can file grievances related to the agreement. Both side agreed to meet every six months to keep within the spirit of the agreement.

What we know about the planned casino

The tribe is building the casino off its traditional checkerboard reservation. It purchased the property and is waiting for approval from the Bureau of Indian Affairs to add the land into a federal trust before it can move forward, Tom Davis, chief planning and development officer for the tribe, has said.

Because that timing is unclear, it's uncertain when the tribe will break ground or when construction will be completed.

According to a draft environmental assessment and tribal environmental impact report, the tribe intends to develop a casino, parking, restaurants, bars, retail, mixed-use space and tribal government office space. The tribe estimates the new development would generate 556 jobs at the casino and mixed-use facilities on site. The casino would be open 24 hours a day, seven days a week.

The casino would have 500 Class III gaming machines such as slot machines and roulette, and eight table games. That's about one-third the number of slots as at the Agua Caliente Resort Casino Rancho Mirage, which has 1,450 machines, 48 table games, a live poker room and high limit games.

"The 556 jobs that the Agua Caliente Casino will create in Cathedral City by opening a new casino will enable many people with an opportunity to seek careers with a stable thriving employer that has always been a good corporate citizen," Joe Wallace, CEO of the Coachella Valley Economic Partnership, said in a written statement regarding the casino in August. "The strategic location with proximity to the downtown shopping district has the capacity to provide an economic stimulus to the offerings that are available while adding to the entertainment options in downtown Cathedral City."

The tribe first announced plans for the casino in Cathedral City in April 2017 and paid $5.5 million for the land later that year.

"This is about making a large-scale investment in Cathedral City," Agua Caliente Tribal Chairman Jeff Grubbe said in a statement at the time. "The future development will create jobs, revitalize an undeveloped downtown property and support Cathedral City's economic development efforts."
