Abstract The present study aimed to generate a redevelopment model of suitability evaluation in the suburb brown-fields of western Mashhad, northeastern Iran. Redevelopment model assists urban municipalities and environmental agencies through making a cleanup place and a healthy environment. In this regard, using fuzzy logic and GIS, a place making procedure was applied to analyze ten effective spatial variables including elevation heights, slope, aspect, geological units, soil units, land covers, ecological resources, rainfall, proximity to roads, and proximity to water wells. By combining layers using the normalized fuzzy membership functions in GIS, a final map of land suitability evaluation was produced. According to redevelopment modeling, the prone zones of faults and floods hazards were eliminated from the suitability map of the brown-fields. Therefore, fieldwork survey indicted rational requirements of the land suitability to regenerate designable uses and services in order to design an upper hand redevelopment plan to conduct regional and local place makings. Estimation of model accuracy revealed a strong relationship (R2) between suitability classes and real estate inventory using scatter plot equal to 0.83. Hence, the redevelopment model represented an appropriate accuracy in predicting the redevelopment expansion in the brown-fields of the study area.

1 Introduction Approximately 55% of the world’s population currently living in urban and suburb regions (World Bank 2015) and ~ 60% of the population will settle in these regions by 2030 (Boyko et al. 2005). Urbanization is caused by the spatial changes in population and various other socioeconomic dynamics (Arsanjani et al. 2013). Rapid urban expansion induces urban land use change and environmental degradation that can lead * Sona Bikdeli [email protected] 1

to severe effects on inhabitants (Benenson and Torrens 2004; Czamanski 2008; Bhatta 2010). Developing urban and suburb regions have been faced by several unsustainable development issues such as expansion, reconstruction, and redevelopment. (Girardet 1999). New approaches to sustainable development require comprehensive analysis, understanding, and modeling of urban systems (Herold et al. 2003; Asgarian et al. 2014). In this regard, land suitability can play an important role in sustainable urban development and redevelopment (Cao et al. 2012). Redevelopment of the urban and suburb regions can regenerate progressive plans into brown-fields. Brown-fields are defined as vacant or destructed areas with previous uses such as military, transportat
