Abstract
The renewal plan of historic viaduct the High Line in New York was carried out mainly by activities of Friends of the High Line (FHL), a nonprofit group. They have overcome the difficulties regarding the consensus building and plan making. In this paper, we discussed the renewal process by focusing on relations among stakeholders, the concrete contents of an accepted renewal plan and FHL's way to show renewal advantages. Through the analysis of primary sources, we have been able to show that: (1) FHL had developed the renewal plan in cooperation with another nonprofit group. This plan indicated the renewal of surrounding area. It has been accepted by New York City Council and new Mayor. (2) This made FHL act as a planner. Then FHL shaped the plan and showed renewal advantages to stakeholders thorough the review of previous alternative plans.
