Kroenke has designed an 80,000-seat stadium for two clubs with two home locker rooms, identical sets of office space and two owners' suites.
His plans for an NFL stadium are in direct competition with a joint proposal by the San Diego Chargers and Oakland Raiders to build a $1.7-billion two-team stadium in Carson.
Backers of the shared stadium plan to march to Carson City Hall and hand-deliver 30 boxes of petition signatures in the next couple of days. The delivery, complete with a marching band, was scheduled for Monday, but was postponed.
"We have been up all night confirming petition signatures and although we've passed the mark we won't submit until we've validated them all, so the submission will be postponed but happen in the next couple of days. Stay tuned!!!" Carson2gether, a coalition of community leaders, with major funding by the Oakland Raiders and Charges Football Company, LLC, posted on their Facebook page Monday morning.
It took a coalition of supporters, including labor unions, a little over a week to gather more than 14,000 petition signatures from registered voters in support of the joint proposal to build a 72,000-seat stadium at Del Amo Boulevard and the 405 Freeway in Carson. That's if both teams fail to get new stadiums in their current hometowns.
With enough petition signatures, the stadium project will go directly to the Carson City Council, which can either outright approve it or place the issue on an upcoming ballot. The Carson Planning Commission will meet Tuesday night and could form a recommendation for council members.
The NFL reportedly considers L.A. a two-team market and wants a stadium that could accommodate both teams. Kroenke gathered with the NFL league in Phoenix Monday and unveiled his design for the two-team stadium.
HKS, Kroenke's architectural firm and the designer of stadiums for the Dallas Cowboys and Indianapolis Colts, estimates the project would take fewer than three years to build.
An NFL team has not played in L.A. since 1994. Under current rules, the next opportunity for a team to file to relocate would be in January 2016.
Any franchise would need the support of at least 24 of the league's 32 owners to move to the nation's second-largest market.
