Traditional zoning approaches have restricted, regulated, spatially isolated, and pushed industrial land to the periphery of cities, resulting in a significant loss of urban industrial land across American cities. But as the United States experiences a manufacturing renaissance and cities begin to recognize the value of centrally located industrial land in its contribution to the regional economy, planners are grappling with the issue of how best to secure these viable but vulnerable sites of employment and production. Advanced technologies that are changing the nature of manufacturing and logistics present an exciting opportunity and potential solution: the industrial mixed-use zone. This thesis explores the emerging land use tool of industrial-mixed use zoning, using Los Angeles as a case study. ; The intent of the industrial mixed-use zone, which permits non-industrial uses, to varying degrees of intensities, in otherwise industrial districts, is to protect central locations for industrial operations when market forces might otherwise price them out. On the one hand, the zone can impede industrial business displacement through offering protection to compatible lighter industrial uses in transitioning neighborhoods. In doing so, it aims to create a live/work urban district in which several planning agendas are met and balanced, providing for industrial employment alongside affordable housing and public realm improvements. On the other hand, without strict use definitions, mix requirements or consistent regulation, the industrial mixed-use zone risks both accelerating the land use conversion process, operating as residential and commercial upzoning, and gentrifying industrial districts toward more artisanal and boutique industrial operations. ; In 2019, the Los Angeles Department of City Planning will rezone industrial land in Downtown Los Angeles under a new zoning classification: hybrid-industrial. Through an exploration of Los Angeles' industrial land use policies, a process tracing of the evolution of hybrid-industrial zoning, and a dissection of the zoning ordinance's text, this thesis demonstrates the trade-offs associated with a mixed-use district and the potential challenges and pitfalls of implementation. ; by Sarah Brown. ; M.C.P. ; S.M. in Real Estate Development ; M.C.P.
