While Fisherman’s Wharf merchants worry proposed closures of The Embarcadero for bicycling, jogging and dancing will hurt business, the Mayor’s Office said it is “supremely confident” they will have a positive impact on the economy.

The Board of Supervisors will vote today on legislation calling for The City’s Controller’s Office to conduct an economic analysis of the closure.

Mayor Gavin Newsom is moving to ban cars along part of a six-mile route from the Bayview to Chinatown on two Sundays — Aug. 31 and Sept. 14.

Board of Supervisors President Aaron Peskin had introduced a measure requesting an economic impact report and another requiring such events to obtain approval from the Board, but he withdrew the latter Monday.

“We are supremely confident that an economic impact report will show a positive benefit for The City,” said Mike Farrah, director of the Mayor’s Office of Neighborhood Services.
