ANAHEIM – Towering digital displays flash from a high-rise complex filled with condominiums, offices and entertainment options surrounding Angel Stadium.

That’s one architect’s vision for what could be built on the stadium’s 133-acre parking lot as part of the larger Platinum Triangle, a massive residential/commercial plan in the stadium area.

The conceptual drawings by Gensler & Associates were ordered by the city last fall, shortly after the Angels walked away from stalled negotiations for a new stadium lease.

The renderings were shared with the Angels several months ago in an attempt to kick-start talks, but the team hasn’t returned to the bargaining table and continues to explore options outside Anaheim.

“There’s tremendous value on that property that could be gained if we developed this with the Angels for a win-win situation,” Mayor Tom Tait said. “It’s one thing to say what’s entitled to be built there, but the renderings help put everyone on the same page to actually see what can be done.”

Under the current stadium lease, any construction on the city-owned parking lots would need input and approval from the Angels. Team concerns might include maintaining the guaranteed 12,500 surface-level parking spaces to maintaining the stadium’s sight-lines to the nearby 57 freeway.

“The stadium property has always been an important development opportunity for the city, and these renderings demonstrate how the team can be an important anchor and economic engine in the future,” Angels spokeswoman Marie Garvey said.

With Angel Stadium as the centerpiece, Gensler’s architects based their idea on a city-approved zoning plan that calls for building up to 5,175 condominiums or apartment units, 3.12 million square feet of office space, 3.12 million square feet of commercial space and parking structures clustered onto the parking lot. The Great Recession stalled those plans.

A spokeswoman for Gensler declined to comment.

“We’ll be looking at multiple opportunities, I assume, as we move forward with negotiations, but this is one dynamic possibility,” Councilwoman Kris Murray said.

A city-hired appraiser said last year that it would make more sense to develop less on the parking lot than zoning permits, suggesting instead: 3,070 housing units, 410,000 square feet of retail space and 750,000 square feet of offices after making room for roads and parking spaces.

“We need to understand what is physically possible out there and this is part of the education process,” John Woodhead, Anaheim’s community development director, said of the renderings.

“There is capital coming into Southern California to pay for something like this … but we haven’t explored the market yet to determine any interest,” Woodhead said. “It’s something I aspire to get with our partners, because it’s an exciting opportunity that brings another great destination to Anaheim.”

An unspecified amount of revenue could be further gained by installing giant digital billboards on the soaring towers.

Gov. Jerry Brown signed a bill in October 2013 that allows electronic billboards to be built within 1,000 feet of city-owned ballparks and arenas with more than 15,000 seats. Cities like Anaheim have until Jan. 1, 2019, to adopt ordinances permitting the signs.

At the same time, the Angels have a window from 2016 to 2019 to get out of the lease for the 45,000-seat stadium. If the team doesn’t opt out, then the current pact runs through 2029.
