Julie Driscoll has had her flower and gift shop at 39 Abercorn St. for 14 years, according to her mother, Betty Dicamillo, who also works there.

Locals and tourists alike can be forgiven, however, if they mistake The Garden on the Square for a surf shop during the coming weeks. With the recent addition of a surfboard outside the shop's window, the store is being disguised as a wave rider's destination of choice for the movie "SpongeBob SquarePants 2."

Dicamillo said there may be some disruptions to her business, but the attention the movie brings to the city will make it worth it.

"I'm really excited," Dicamillo said. "It's good for Savannah."

Savannah officials held a press conference Monday on the corner of Broughton and Drayton streets, where other buildings have been painted to resemble a beach community, in order to let businesses and residents know how the production will be impacting downtown.

Will Hammargren, location specialist for the city's film services office, said that filming began that morning on Tybee Island and is set to start downtown on Monday and last through Oct. 18.

While there will be some live actors, most of the disruption will be caused by filming equipment, Hammargren said. Some sections of streets will be closed at times while the production takes place and the specific details will be issued prior to the day of filming, he said.

Hammargren said the production company estimates it is making an $8 million investment in direct spending in the Savannah area, including booking at least 5,600 hotel room nights. About 1,300 locals are expected to work as extras for the movie.

Michael Jarema, chairman of the Savannah Film Commission, said film and television projects in Savannah had an economic impact of $26 million in 2012, which included $12.2 million in direct spending.

"With 'SpongeBob' I think we have a good chance of equaling or surpassing that," Jarema said.
