Abstract Paying attention to the urban landscape is always one of the most important research and executive concerns of researchers and experts in the field of architecture and urban planning, considering that it includes the most visual communication of citizens with the city and transmits a lot of information from the surrounding environment to people. Today, due to the lack of coherent standards and accurate and correct supervision of its implementation in the field of urban facade design and implementation, we are facing a kind of visual turbulence and crisis in the landscape of urban facades. Therefore, by defining programs with the framework of managing and rearrangement ugly urban landscapes, by the urban management, it is tried to take steps to improve the visual quality of these views with different solutions. Thus, according to the amount of intervention in the facade components in order to apply reforms in the form of renovation, rearrangement and trimming out of urban facades, in some cities, with the intervention of the municipality, executive measures have been taken in this regard. Hence, in this research, an attempt has been made to review one of the most recent experiences in this field in the city of Isfahan (Askariyeh and Alam ol-Hoda streets) in the form of a scientific and executive process, and to present the lessons learned from this experience. In general, this study seeks to find an answer to this question that: “what measures can be taken to improve the urban landscape of the existing urban facades? And then by introducing 10 scientific and executive steps in the project which is entitled “preparation of executive documents of the trimming out, renovation, rearrangement and monitoring of implementation”, the strategies obtained in the framework of its plan are presented as urban trimming out measures.

Abstract Abstract
Considering the application of sustainable urban regeneration approach in the field of urban  management and urban planning, conducting study and executive projects in this field can be seen in the executive perspective of many organizations responsible for making decisions in the city. One of the projects that has recently been considered by the Isfahan Municipality in the neighborhoods of the 15 districts in this city and has service description and study process very similar to the concept of urban regeneration is "Isfahan neighborhoods quality improvement project". Considering the comprehensive view toward the texture of the neighborhoods and applying methods of inhabitants' social participation in advancing the project, these projects seek to apply the sustainable urban regeneration approach in the form of executive and applicable tools. What is of great importance in these studies is the experiences from the previous studies in three general levels: carrying out the studies, formulation and approval of plans, and implementation of the final plans. Despite numerous positive points in formulating the mentioned plan and theoretical and practical similarity with the concept of urban regeneration, the challenges and deficiencies are inevitable as there is little research in this field. Therefore, the present study aimed to investigate the positive points of the plan as well as the challenges in two general parts: legal challenges and executive challenges, and to compare these challenges in three neighborhoods of Isfahan through a brief look at the experiences from the quality improvement plan of the three neighborhoods. Obviously, there is no space to provide all strengths and weaknesses in this paper, but it tried to provide the most important features, as a tangible practical experience in connection with the social, cultural, and physical contexts of the project.
