Cultural preservation efforts have evolved from traditional, site specific projects administered by a single agency, to regional, multi-jurisdictional projects administered by a cooperative partnership. The projects administered cooperative partnerships are a recent phenomena and are often termed heritage preservation projects. An analysis of the evolution of cultural preservation efforts is undertaken through historical and case study research. The selected cases are examples of innovative regional cultural preservation efforts of their era. The results of the analysis provide a descriptive evolution of the cultural preservation efforts, and a description of the components of both traditional preservation efforts and heritage preservation efforts. / Master of Landscape Architecture
