(Credit:Courtesy Image) The Comprehensive Plan task force experienced its first major hiccup with word that one of the two consultants who started on the effort to develop a road map for Shelter Island’s future had to abandon the project because of health-related issues. Replacing Lisa Liquori of East Hampton-based Fine Arts and Sciences could have been challenging for the other consultant, Peter Flinker of Dodson and Flinker of Florence, Mass. But Larissa Brown, Ph.D., of Larissa Brown & Associates in Cambridge, Mass., stepped into the role Jan. 4. Ms. Brown and Mr. Flinker have worked together before; she has more than 25 years of planning experience.
