Rehabilitation of Tissue inside the city with form-based zoning approach Case Study: Borazjan city

Horizontal expansion phenomenon in the last half century, not only in developed countries but in developing countries has occurred. This phenomenon has spread into areas of marginal and outer space arbitrarily banning city and as low-density development and detached. Today our cities, with the development and increase access to physical space and new territory, beginning from within their own quality Azdstdadh depleted and many of the surrounding areas more and more developed, and any attempt to draw urban development program to deadlock. With the abnormal increase of population, especially urban population in iran in the recent decades, the issue of the environment and the spatial sustainable development of considerable importance have been.Urban population growth. in iran with sprawl development of the city and eliminating agriculture and natural resources of surrounding towns have been demolished,While many cities have space resources and are valuable but Deteriorated. The solution for many of the problems caused by cities now is the problem of Regeneration and the Revitalization of these. Valuable spaces are considered In this regard, Smart growth approach in the United States of America as defined management model, pay special attention to the capacity of the inner city. In this The approach, Defined principles and tools for land management and in the system the country's urban planning are applied. These executive instruments guide development the land so that it would occur in the landscape the land development. On this basis, the main idea of this research, the development of the inner city, with emphasis on the development of this tissue is too old to reminde this fact that As long as the capacity of the old tissues are in cities, Steer development towards the Cities around will cause instability in the Framework of the city. Therefore, in this study, using form-based zoning model is one of the Instruments smart growth approach, Area and neighborhoods Borazjan City according to Smart growth coding system In Software GIS Through the Respective indices were zoning in Three general Regions, communities and zones. The three levels are networking with each other. In the areas that are the equivalent regions Potential development areas in six separate sections determined. There are three zones at the community level that The development model defines six areas. In the third level, each of the areas of natural and rural zones to urban core part of the spectrum is divided. Accordingly, the use of spatial analysis software, GIS, suburban areas and penetration Borazjan, According to the above levels, Under transected was placed. Finally, according to the model using form-based zoning Borazjan, to test the assumptions. The study Distressed neighborhoods located in an area of 229 hectares and a population of 21614 people Borazjan (Population and Housing Census, 1390) that it completed the relevant information needed to be collected. Based on the research aims to study the development of endogenous damaged, Using smart growth approach, form-based zoning model Borazjan were included. The purpose of The implementation of this model, to meet the assumptions of the study. The performance of the model form-based zoning, zoning out city in six different areas in terms of power and talent development. Each of these zones based on indicators that are, On the part of the form and structure of a certain capacity to adapt to any development, respectively. In this zoning, the study area of research, In the subset of zone (G4), the area was re-qualified talent development. Therefore, according to this model, The first hypothesis, "old textures and Central Borazjan have the potential redevelopment" Was approved. The second hypothesis of the research is based on this theme"Using form-based zoning in smart growth development model old textures Borazjan be revealed." In order to verify this hypothesis, two gross population density and parts size were analyzed in the study area. Then using spatial analysis of these two indicators in the software ARC GIS, The results on the zone (G4), combined and integrated, and finally, two pattern (TND) and (RCD) In order to Old texture of community development. zone (RCD), the potential development of commercial orders and mapping (TND), the potential development of urban areas and regional centers are to having. In the third step of the analysis, Each of the two zones assigned to the T-Zone (transected) were divided. At this stage, the identity of any part of the urban environment to urban nucleus was determined. This research Is part of the Applied Research and of The method Part of the research is analytical and documentary field. In the process of researching and defining the principles and practices investigated And to perform old studies on the structure of the population, use, physical and access have been discussed. According to what is said in relation to determining the pattern of development in each of the zones And necessity steer development to areas inside the city and protection of agricultural land and natural resources around the city It can be said the best area In order to future development Borazjan, old textures and city center. Led development of the city, within the context of old downtown, can be reduced to the extent of sprawl around the city and pulled it off. In this regard The use of smart growth strategy and Principles in the urban development plan, can accelerate this process and order and direction of future city growth and development within the context of old and inefficient guide. If you enter the land into city limits is inevitable due to the classification of land around the city based on factors such as soil type, erosion, land slope, soil depth and texture, the irrigation, drainage, water-holding capacity and so as much as possible is agricultural land that has less talent are to be added to the city limits.
