Many works of modernist landscape architecture are currently threatened. Due to their relatively young age, many do not meet the 50-year period set forth by the National Register of Historic Places. Those still extant have often been subjected to unsympathetic modifications and additions. More still have undergone insensitive adaptations, compromising their integrity and rendering them nearly unrecognizable as representations of notable design. Many suffer from original design or construction flaws. Miscommunications and misunderstandings due to differences in terminology and opinion arise when deciding when, where, and how to treat these landscapes. Few have been effectively preserved or restored. Those that have escaped demolition remain in the hands of private owners who have the capability to allocate necessary funds for preservation and subsequently high level of maintenance. In addition, these endangered landscapes commonly face negative public perception. Oftentimes these historic sites are viewed as outdated, dangerous, or aesthetically displeasing.
As a graduate student with a background in landscape architecture, my interests in historic preservation and landscape architecture led me to become interested in modernist works and their endangered state. My graduate thesis looks at the rehabilitation of significant modernist park plazas in urban settings, the actions and actors involved in the intervention, and the ultimate result of the revisions to the landscape. The purpose of my research was to determine common issues in interventions at significant modern urban park plazas for contemporary use and generate a set of considerations for future preservationists to follow. (For the purpose of the thesis, a modern landscape is a designed landscape constructed during the mid-to-late 20th century, inspired by the modern movement in art and architecture.)
