Urbanization processes and incremental approaches ignore, even destroy, the continuity of the built environment that is defined with the historical traces. Planning studies, which aim to provide continuity or create the future with references of the past, require a comprehensive and pro-determinist urban analysis. This study aims to analyze existing city and its communication with former layers to reveal continuity of the city. Such analysis can be defined as reading urban layers, or typological-morphological analysis including social dimensions that create layers. In this context, urban typo-morphological approaches and on conservation development plans is handled. Existing legal framework and Technical Specifications of Conservation Development Plan is evaluated and, conservation development plans prepared through these specifications is criticized as their insufficiency for multi-layered historical cities. An analytical method is presented to read urban texture diachronically and synchronically as an attempt to improve integrated conservation methods. Especially, reading method of Caniggia and Petruccioli, representators of Italian Morphology School provides knowledge to constitute the method. Some parameters are formed in an attempt to understand formation process of multi-layered historical cities.
