Mayor Cherelle L. Parker said that the city will “start from scratch” on a new community benefits agreement, canceling the hotly debated plan with the 76ers and making way for a new one now that the arena is planned for South Philadelphia.

The team's deal with Comcast Spectacor in South Philly includes investments on East Market Street, but few details are known.

The team, whose ownership group is led by investor Josh Harris, said it had formed a 50-50 joint venture with Comcast to replace its arena in the South Philadelphia stadium district by 2031. Comcast will also take a minority stake in the team and work together on the WNBA bid, the parties said in a joint statement Monday.
