T.U.S.C.A.
T.U.S.C.A. was a transportation and land use plan for Puerto Rico, created in 1970-1971.
T.U.S.C.A. stands for “Transportation and Urban Settlement Combined Action”. It was a visionary transportation and land use plan prepared by Architect Etienne Dusart, heading up a team of architects, landscape architects and transportation planners and engineers during 1970-71. The plan was prepared by a team of planners, engineers, and landscape architects, headed by Etienne Dusart for the Commonwealth of Puerto Rico's Planning Board. Due to the unwillingness of the Commonwealth of Puerto Rico to invest the necessary resources in the project, the plan was never implemented. Twenty years later, David Fairchild, one of the original planners for T.U.S.C.A. headed up a plan to design the 'Tren Urbano' heavy rail transit system, but only for the metro area of San Juan, and without the land use component of the original plan.[1]
Preparation of the T.U.S.C.A. plan was financed jointly by both the United States Department of Housing and Urban Development (HUD) and the U.S. Department of Transportation (DOT Contract No DOT-UT-402) and by the Government of the Commonwealth of Puerto Rico. Its purpose was to connect the cities and towns around the entire coastal plain of the Island of Puerto Rico with a transit system and to construct a series of new towns served by that transit system.
