Three San Francisco parks will be rebuilt in an $8 million project that begins this week, according to the nonprofit Trust for Public Land.

Yomi Agunbiade, the general manager of the Recreation and Park Department, will join Mayor Gavin Newsom, TPL representatives and officials from four of The City’s largest companies at Hayes Valley Playground on Thursday to help launch a San Francisco chapter of the nationwide Parks for People campaign.

According to the TPL, Hayes Valley Playground in Hayes Valley/Western Addition, Balboa Park in the Excelsior and Boeddeker Park in the Tenderloin are scheduled to be rebuilt with a $4 million challenge grant.
