Property problems in post-earthquake urban redevelopment process : a case study in city of Adapazarı

Erten, Mustafa Güven
This thesis investigates the underestimated ownership constraints in built-up urban areas as the determining characteristic of the urban redevelopment process after the Marmara Earthquake. In the first part of the study, public provisions for permanent housing have been surveyed. It is observed that relocation of the survivors entitled to such housing sites considerably far away from existing urban areas has generated the need for many adjustments on the property patterns. Without any framework for the remaining ownership and development rights in those damaged urban areas, nearly 43 000 housing units have been developed mostly by the state in order to compensate for the lost properties of disaster survivors. On the other hand, municipalities could not commence any considerable redevelopment framework in damaged urban areas after the earthquake. They were restricted to revising their development plans with respect to new geological surveys and to redefining the ideal building regulations with low building heights. Adaptation of these renewed plans to existing conditions has necessitated an immense amount of property readjustments. However, this is nearly impossible with existing plan implementation instruments which are incapable of mandating the exchange mechanisms for the reduced development rights. Lack of three dimensional property adjustment and purchasing methods different from constructions option engendered the implementation problem of these development plans prepared after the earthquake. In this framework, a field survey has been carried out in the city of Adapazari and the post-earthquake urban redevelopment process is investigated. Transformation of the properties are plotted in ark Street, where the required resharing of reduced development rights with respect to new development plan can be partially observed. Besides, the success of the forthcoming
