After receiving a D grade in a report compiled by local park advocates, West Portal Playground was the focus of a news conference Wednesday morning in support of a parks bond that will appear on the November ballot.

Supervisors Malia Cohen, Carmen Chu and Sean Elsbernd joined San Francisco Parks Alliance Executive Director Matthew O’Grady and others at the playground at 131 Lenox Way to encourage passage of Proposition B, a $195 million bond that would provide $15.5 million for playgrounds in need of renovation.

The report, which has been compiled by the alliance every two years since 2006, gave 16 of The City’s 129 playgrounds D or F grades. The quality and safety of play equipment and playgrounds’ accessibility to the disabled were considered in assigning grades.
