Monday's proposal is the latest in a decades-long struggle over who rules and uses the beach. Besides recommending a rope, the panel also wants people to be banned during pupping season and dogs to be banned year-round.
The committee's proposal goes to the full City Council. If approved, it will require permits from the California Coastal Commission.
The artificial cove, created by a seawall in 1931 and donated to the state, was used as a children's pool until the seals moved in during the 1990s.
Councilman Carl DeMaio said the city has a real treasure with Children's Pool and the seals are part of that. Critics, however, have argued that the marine mammals' waste makes the pool unhealthy for use by humans. In 1997, the city posted a warning that the cove shouldn't be used because of high bacteria levels.
