This paper presents an inventory and an analytical model regarding the diversity of current uses found in the post-industrial landscapes of the former textile cities of Lowell, Massachusetts and Norrköping, Sweden. The model relates the diversity of current uses found in these regenerated, post-industrial landscapes to the priorities emphasized in their redevelopment process, which is relevant because opposing ideals such as regeneration and diversity may collide with those of preservation and conservation. Empirical data gathered primarily by observations and theories relating to the importance of diversity/multi-functionality in urban settings form the basis of the paper’s analysis.
