Thesis Synopsis: The number of homeless sleeping outside in Seattle has increased significantly in the past few years, from 2,600 in 2012 to 4,500 in 2016. In response, the City has begun to spearhead the development of temporary sanctioned homeless encampments on vacant public land as an innovative alternative to an overburdened emergency shelter system. Vacant land remains a valuable, limited commodity in the rapidly growing Puget Sound region, however, making it difficult for the city to want to remove developable land from its inventory, even if only temporarily. Thus, land beneath and adjacent to rights-of-way presents an option for the placement of homeless encampments that doesn't utilize developable land. This thesis looks to expand upon the City of Seattle's current site selection process for encampments by considering these covered liminal spaces as a viable option.
