Several structures are being built, including a large dining hall, a stage for the ceremony, a sound-proof room for music, and bathrooms.
The property owner is the Donald G. Fisher Trust, according to county records. Mr. Fisher, who died in 2009, was the founder of The Gap clothing stores. A spokesperson for Fisher Development Inc., a contractor on the project, said: "The family does not wish to comment and appreciates your understanding and respecting their privacy."
Although the construction involves a slab of concrete and structural framing, because the project is temporary, it did not fall under regulations that would have required a building permit, Town Manager Kevin Bryant said. The Town Council will be looking into ways the town can have oversight in cases such as this, where the construction is temporary.
Upon learning of construction activity going on, town staff visited the site and issued a stop-work order to provide time to deliberate over how to respond, Mr. Bryant said. Staff gave its approval to continue the work, and issued a demolition permit to Fisher Development. That permit requires the property to be returned to its original condition when the ceremony is over, Mr. Bryant said.
"When someone is going to hold a wedding, you don't want to tell them that they can't hold a wedding," Mr. Bryant told the Almanac.
Members of the council agreed. The wedding came up for discussion at the council's Sept. 10 meeting.
"We want people to enjoy their property," said Councilwoman Deborah Gordon. An ordinance regulating such activities should establish a reasonable time frame for setting up and tearing down temporary structures, council members said.
"It's the preparation for the party that is the inconvenience," said Mayor Anne Kasten. "To my mind, that's a little bit of a burden on the town. ... All of us regard the land as sacrosanct around here."
The applicant has been "very cooperative," Mr. Bryant said. The entire project — from the laying of the boardwalk and concrete to restoring the site to untended grasslands — began in mid-August and is expected to span between six and seven weeks, he said.
The ceremony is expected to draw about 400 to 500 guests, Fire Marshal Denise Enea of the Woodside Fire Protection District said. Classic Party Rentals, based in Burlingame, obtained a tent permit from the fire district and there will be a couple of firefighters on hand during the wedding, Ms. Enea said. The temporary complex is governed by the same fire-code regulations that apply to permanent structures, she said.
The guests will arrive and depart by shuttle, she said.
Asked if this wedding was unusual in terms of size and complexity, Ms. Enea said that it was not. "People throw some extravagant parties here in town. We've had quite a few of them," she said. "There's actually, I think, very little impact to the site. ... It takes months of planning and it's over in one night."
