Planning evaluation can take place at three different times: ex-ante, on-going, and ex-post evaluation. The latter two receive relatively little attention in the literature due to the lack of resources, the norms of organization culture, and the limited availability of data and analytical methods. As the legitimacy of planning and its effects has been increasingly questioned in Taiwan, this study takes on the challenge of the ex-post evaluation, to evaluate the effect on plan implementation on the ground in Taiwan, using a case study of a detailed plan of a land readjustment neighborhood in Tainan City to empirically demonstrate the quantitative evidence for planning implementation. Due to the regulatory planning system in Taiwanese city areas, this research takes a conformance-based approach on planning implementation evaluation. The mismatch of land use, built area ratio, and floor area ratio will be analyzed quantitatively for its spatial distribution, patterns of concentration, and potential social-economic factors that may be associated with the implementation. An empirical assessment of the gap between plan and outcome is the foundation to define the success or failure of the plan in its relationship to the urban development process. This study is a significant attempt to provide empirical evidence on the effect of zoning and the ability of a plan to create change in Taiwan. As New York City’s Zoning Resolution reaches its first centennial, this study attempts to join the international dialogue on connecting planning theory, planning practice, and education.
