Commissioners approved the field 4 to 1 during an acrimonious and emotional hearing.
The soccer and rugby field, which would replace a dirt and weed-strewn lot behind St. Francis of Assisi Church on Bay Road, has been four years in the planning by Mr. May's family and friends through the Rich May Foundation.
The family wanted to establish the field as a way to help keep youth in the city engaged and out of gangs, foundation member Frank Merrill, Mr. May's stepfather and a resident of Atherton, has said in previous interviews. Mr. May was shot and killed in 2006 by Alberto Alvarez, an East Palo Alto gang member who has been sentenced to death for the killing.
Planning commissioners have been hesitant to allow the playing field, with some citing traffic congestion.
Tami McMillan, Mr. May's sister, said the traffic issue is being mitigated by a 500-foot setback for the passenger drop-off area. During the meeting, an emotional exchange erupted between Ms. McMillan and commission Chairwoman Renee Glover Chantler.
Ms. McMillan said a small group of people within the city were supporting the status quo. "The status quo killed my brother," she said.
Ms. McMillan said the issue was scheduled for the end of the meeting, when kids and other supporters would not be able to stay because of the late hour. A few people in the community were letting small political issues get in the way of helping the kids, she said.
She said she believes opponents will appeal the decision.
