Repair costs for San Francisco’s Stern Grove balloon to $20 million, 5 times initial estimates
The cost to repair flood-damaged Stern Grove in San Francisco ballooned to $20 million, according to a recent report from the San Francisco Public Utilities Commission — five times more than the $4 million city officials initially estimated. The concert venue’s hillside was washed out after an air release valve failed during maintenance of a 54-inch diameter water line last August.
