Expensive racing sailboats may not be the only craft on San Francisco Bay once the 34th America's Cup rolls into town.
Water space could be filled with commuters, too, seeking a respite from the roads, railways and bus lines jammed by the yachting race.
The 500,000 daily spectators expected to converge on the city during race days in 2013 will jam roads and will overload Muni and BART lines unable to handle the spike in ridership, according to the San Francisco Examiner.
The stress on public transit are just one of the impacts of the race outlined in a 1,600-page report released Monday. Deletrious effects on butterflies as well as parks and other city resources are also expected, the newspaper reported.
The full environmental report will be released by the end of the year, a "lightning speed" evaluation, according to the newspaper: most reports of this magnitude take up to two years to complete, while this one has been fast-tracked.
