The twentieth century land use plan has evolved from simple roots in civic design and zoning into an intricate combination o f design, policy, and management. Its family tree illustrates how new branches growing from different disciplinary roots have been integrated into contemporary hybrid plans. A source o f the vitality o f traditional land use planning has been its ability to respond to and incorporate new approaches, including verbal policy plans, growth management plans, and land classification plans. Despite predictions o f its demise, land use planning is still a mainstay ofefforts to manage community change, while becoming more participatory and electronically based, and concerned with increasingly complex issues.How a city's land is used defines its character, its potential for development, the role it can play within a regional economy and how it impacts the natural environment.Seattle Planning Commission 1993uring the twentieth century, community physical development plans have evolved from elite, City Beautiful designs to participa-D tory, broad-based strategies for managing urban change. A review of land use planning's intellectual and practice history shows the continuous incorporation of new ideas and techniques. The traditional mapped land use design has been enriched with innovations from policy plans, land classification plans, and development management plans. Thanks to this flexible adaptation, local governments can use contemporary land use planning to build consensus and support decisions on controversial issues about space, development, and infrastructure. If this evolution persists, local plans should continue to be mainstays of community development policy into the twenty-first century. Unlike the more rigid, rule-oriented modern architecture, contemporary local planning does not appear destined for deconstruction by a postmodern revolution. Though critics of comprehensive physical planning have regularly predicted its demise (Perin 1967, Perloff 1980, Jacobs 1992, Friedmann 1993,' the evidence demonstrates that spatial planning is alive and well in hundreds of United States communities. A 1994 tabulation found 2,742 local comprehensive plans prepared under state growth management regulations in twelve states. (See table 1.) This figure of course significantly understates the overall nationwide total, which would include all those plans prepared in the other thirty-eight states and in the noncoastal areas of California and North Carolina. It is safe to assume that most, if not all, of these plans contain a mapped land use element? Not only do such plans help decision makers to manage urban growth and change, they also provide a platform for the formation of community consensus about land use issues, now among the most controversial items on local government agendas.This article looks back at the history of land use planning and forward to its future. It shows how planning ideas, growing from turn-of-
