160Clustering, reinventing, and hybridity are three contemporary approaches to developing industrial areas. Industrial clustering is a concept defined as a socio-spatial assemblage of people, buildings, and activities without any necessary center, boundary, or scale, where the production processes of some service-sector firms depend on infrastructure in a fixed, physical location. Industrial regeneration is a concept that refers to processes that boost existing industrial uses and reverse possible decline by improving the physical infrastructure, protecting and enhancing current land use, and building on the urban characteristics of the place. Hybridity is a relatively new concept that offers a spatial framework of mixed-use industrial zoning to preserve industrial districts in cities. Using the principle of densification, this framework proposes to construct hybrid buildings and districts based on the principles of walkability, alternative transportation, and neighborhood retail.
