SAN FRANCISCO (AP) — A San Francisco supervisor, fed up with the almost-daily displays of nudity in one city neighborhood, introduced legislation Tuesday that would make it illegal to walk around naked on San Francisco streets.

The city allows nudity except in parks, on port property and in restaurants, but under the ordinance by Supervisor Scott Wiener, nudity at city plazas, parklets, sidewalks, streets and public transit would be banned. The legislation would, however, allow nudity at parades and street festivals.

The legislation was spurred by an increase in nudity in the Castro neighborhood, where nudists gather almost every day at a plaza, Wiener said.

Wiener proposed a law last year that would have required nudists to put a cloth or other barrier under their bottoms if they take a seat in public, but he hoped that the situation in the Castro would resolve itself before he proposed a ban on nudity.

"Unfortunately the nudity situation in the Castro, rather than running its course, has gotten more extreme," Wiener said. "Many in the community have reached the end of their rope."

After introducing the legislation, Wiener said it would sit for 30 days before being heard. The proposed ordinance would then go to a committee hearing in early November before going to the full Board of Supervisors later in the month, Wiener said.
