Looking to stamp their claim on the Bay Area after the folding of San Francisco Deltas, The United Soccer League announced the launch of two soccer teams in the region on Monday morning.

The league said that Mark Hall, CEO of Hall Equities Group, plans to bring a soccer team and build a 15,000 seat soccer-specific stadium to the East Bay by 2021. The team will play in the USL which is considered the second division of professional soccer in America, under Major League Soccer.

They also announced in San Francisco the SF Glens, a soccer organization with over 100 youth teams, will join the USL-PDL starting next year which is the fourth division of soccer in America.

“We see a unique opportunity to fill a professional sports void created from the loss of the Oakland Raiders and the Golden State Warriors to venues outside of the East Bay,” Hall said in a statement released by the USL. “We intend to fill that void with soccer, which we see as the up-and-coming sport of the future, both in our region and the nation.” He hopes that a stadium complex with a hotel and conference facility will serve as an economic generator for the selected location.

Although Oakland is mentioned prominently in the press release, the team’s website USL2EastBay.com only states that “USL East Bay will debut in a new soccer stadium in the greater East Bay area built specifically for the team.”

The USL East Bay project is not part of the group Oakland Pro Soccer that has been working closely with Oakland community to bring a professional soccer team to the city.

“We’re just as surprised to see the announcement as everyone else today,” said Benno Nagel of Oakland Pro Soccer. “We haven’t had any contact with them. We’ve been working a long time on how to put a team into Oakland that isn’t just a business and but also improves the Oakland community.” He said that his organization will be reaching out to USL East Bay to share their knowledge and experience with them and see if they can work together.

In fact, Hall appears to have more roots in the Walnut Creek than in Oakland. His Hall Equities Group is headquartered in Walnut Creek, and another one of his business ventures is building a soccer training facility there.

While one organization is attempting to begin a soccer tradition in the East Bay, another club with a history that stretches back fifty-six years, announced that they will be joining the USL’s PDL league and start play in 2018.

The Glens are one of the most storied teams from the San Francisco Premiere Soccer League and twice finished runners-up in the National Amateur Cup. They also have one of the largest youth soccer organizations in San Francisco offering playing opportunities and training for kids throughout the city.

“Since our founding in 1961, the San Francisco Glens have been a fabric of the San Francisco soccer community for generations,” said SF Glens SC General Manager J. Ramon Estevez this morning in their announcement. “With the club’s storied history and the unprecedented growth of our youth operations, joining the Premier Development League provides an exciting new chapter for the club and for all of the city’s soccer players, families, and supporters.”

“SFGE is San Francisco’s club, and we are proud to offer every level of competition from Recreational to the Development Academy, and now our entrance into the PDL with SF Glens SC,” said Mike McNeill, San Francisco Glens Evolution U13+ Director of Coaching. “We are an ambitious club and are driven to raise the standard of soccer in San Francisco and offer a pathway for all players to professionalism.”

The team will have an instant derby with San Francisco City, the supporter-owned club that also plays in the PDL.

The Glens and USL East Bay are among a flurry of recent team announcements in the Bay Area. Another famous San Francisco soccer club El Farolito said last month that they will join the NPSL, a fourth division league in 2018 and AFC San Francisco Hearts said they will join the UPSL, a fifth division league, starting next year.
