Walnut Creek planners will weigh in on Planet Fitness effort to locate downtown

Planet Fitness wants to move into the prime downtown Walnut Creek space formerly occupied by Cost Plus World Market.

The fitness chain will go before the Walnut Creek Planning Commission on Thursday, asking for a conditional use permit to operate in the vacant 18,998-square-foot space at 1697 Mt. Diablo Blvd., in the Olympia Place shopping center.
