Identify the Intervention Arenas in Urban Historic Textures, According to Infill Development Approach (Case Study: Historic Texture of Yazd City)

Historic textures are the manifestation of the lives of past generations, identity, and capital of cities and countries. Growth and progressive development of cities have created social, functional, environmental and physical problems in these textures. The problems need to change in management approach of city development and using approaches such as reconstruction, infill development in order to the revitalization and breathe new life into historical textures. The purpose of this research is to identify intervention arenas in urban historic textures, according to infill development approach. In terms of purpose, the research is an applied as well as in terms of method descriptive-analytic. Physical criteria include land use type, quality building, and old building, building structures, and ownership, number of floors and parcels area. Educational criteria, employment, and population density are as the index social and access to green spaces, health, and commercial and educational land use as an index access. Layers have been normalized by using fuzzy functions membership in the ArcGIS environment. The weighting of criteria has determined with Analytic Hierarchy process method (AHP) and by in multiplying weight in the layers that the final map of intervention arenas in historical texture has been achieved at five class. Results show the first priority 10%, the second priority 17%, the third priority 38%, the fourth priority 25% and the fifth priority 10% have owned the area of the historic texture of Yazd. Planners have to find the methods to identify intervention arenas with consideration of frontage historical building in order to improve social and physical conditions of textures and increase the presence of tourists.
