The urban regeneration phenomenon in Turkey has emerged as a new urban policy in recent years, as is the case in many countries. In this study we examine the relationship between the "general urban regeneration areas" identified on such grounds as "disaster risk, non-compliance with zoning legislation, risky structure, risky ground structure, etc." and "priority risk areas" which have a risk factor in the real sense, in Istanbul. In the first phase of the study, quantitative data (law, year of advertisement, size, current status) related to all regeneration areas in Istanbul, announced under laws 5366, 5393 and 6306, were requested from the Ministry of Environment and Urbanization, the Istanbul Metropolitan Municipality and the district municipalities, and any incomplete information and documentation was remedied from Istanbul Urban Transformation Master Plan analysis data, a desktop study and interviews with district municipalities. In the second phase, "priority risk areas" were defined, taking into consideration the Japanese International Cooperation Agency-JICA Disaster Prevention/Mitigation Basic Plan (2002) report, the Istanbul Earthquake Master Plan (2003), the Istanbul earthquake zones map and the Istanbul Urban Transformation Master Plan Analysis (2016), and their compliance with the "general regeneration areas" was checked from a map covering Istanbul as a whole. It was found that 32% of Istanbul's built-up area border size is in the scope of the general urban regeneration areas. Furthermore, an overlay of the "urban regeneration-development areas" and the "priority risky areas" in Istanbul indicate that the goals of disaster risk reduction and the creation of safe settlements is Istanbul have largely been missed.
