MESA, Ariz. -- The city of Long Beach has approached the Angels to see if the club is interested in building a new ballpark on a waterfront site, according to a report by the Long Beach Post published late Monday night.

The Angels, who have played at Angel Stadium in Anaheim since 1966, confirmed the report.

"As we have stated from the beginning, we must explore all our options to secure a long-term future for the Angels and provide fans with a high-quality experience in a renovated or new ballpark,” Angels president John Carpino said.

The city of Long Beach also released a statement from Mayor Robert Garcia, which stressed that the proposal is still in the preliminary stages. The city has not determined how a ballpark would be financed or if a ballpark would be feasible to be built on the site, which is located on a 13-acre lot in downtown Long Beach.

“We are in the early stages of our due diligence and are exploring a variety of options for this property,” Garcia said. “We have approached the Angels to express our interest and discuss the possibilities of this opportunity.”

The Angels opted out of their lease at Angel Stadium, which would've run through the 2029 season, in October. After meeting with new Anaheim mayor Harry Sidhu in January, both the Angels and the city of Anaheim agreed to a one-year extension through the 2020, which gives both sides more time to discuss a potential new deal to either renovate the current ballpark or build a new one.

Sidhu and the city of Anaheim also released a statement on Monday.

"It's no surprise other cities would try to lure the Angels to leave,” the statement said. “We are confident that the best place for the Angels is and always will be Anaheim, and the one-year extension we granted gives us the time to work out the details and craft an agreement that benefits our residents and the city.”

Angels owner Arte Moreno discussed the stadium situation with reporters early this spring and said he has a good relationship with Sidhu.

“He's been very positive,” Moreno said. “We've been working on a process of the actual needs. We have a 53- or 54-year-old stadium, so we're constantly looking at what we need to do and how we're doing it. We had a structural engineer do something about four years ago, four, five years ago to where it really gave us a long-term plan that we were going to stay there and what needed to be done. They have a copy of that. We're updating that."

Moreno also described what he wants in a stadium, whether it’s a renovated Angel Stadium or a new ballpark.

"Obviously, the first thing we look at is safety, always,” Moreno said. “I would just say overall, you look at the fan experience. People are having to wait in line, how people move through the stadium, how they utilize any concessions or souvenirs or restrooms or just all that flexibility. There's also other areas. We had a lot of families come to the ballparks where, sometimes if there's little kids there's more areas for kids to run around and have a good experience. It's really hard to have a kid sit there for three or four hours. Cosmetically, the new stadiums really have done some things to enhance [the experience]."
