Two of the respondents propose construction of a mixed-use marina and hotel facilities, while the third envisions a tourism-related development.

Bids came from Flagstone Properties, a Celebration, FL-based company affiliated with Miami-based Continental Companies; Swerdlow Marine Partners, a Miami-based affiliate of Hollywood-based Swerdlow Real Estate Group Inc.; and Miami-based Watson Island Partners, an affiliate of Miami-based BAP Development Inc., Bermello, Ajamil & Partners Inc. and N.Y.-based Millennium Partners.

Interest in the development proposals was so intense last week that Miami city officials contracted with Kinko's Inc., the photocopy service, to provide e-mail access to each of the development proposals, in addition to eventually posting limited information on the city's Internet Web site (http://www.ci.miami.fl.us/).
