The 2030 Seoul Neighborhood Plan was established in 2018. It is a plan that embodies Seoul Metropolitan Government's Urban Master Plan at the regional level. It consists of five Sub-regional Plans (several Gu's) and 116 Community Plans (a part of a Gu). Although it varies by period,  eighborhood Plan of Seoul has been continuously established since the 1980s. This study aimed to systematically record changes in Neighborhood Plan of Seoul, which has been established since the 1980s and to suggest future development directions by identifying the role, spatial scope and major characteristics of the Neighborhood Plan. Since  the  1980s,  the  Seoul  Metropolitan  Government  has  continuously established a Neighborhood Plan that embodies Seoul's Urban Master Plan at the sub-regional level. In the 1980s and 1990s, it was established in units of autonomous districts and community areas. In the 2000s, it was established for five sub-regional areas. After that, in the 2010s, the Neighborhood Plan was established for five sub-regional areas and 116 community areas. The key is to determine the spatial scope that is efficient for establishing an  intermediate Plan that embodies Urban Master Plan by region in Metropolitan cities such as Seoul.

Based on operation experience of the Neighborhood Plan of Seoul so far, future development  directions  are  as  follows.  In  the  short  term,  the  Seoul Metropolitan Government needs to establish and operate five Sub-regional Plans. Autonomous districts need to establish and operate 116  community Plans in 25 autonomous districts. It is necessary to integrate contents of Community  Plans  at  the  autonomous  district  level  and  strengthen  the connection with budget to improve feasibility of the Neighborhood Plan. In the long run, the Seoul Metropolitan Government needs to institutionalise the "Autonomous District Urban Master Plan" and use it as an intermediate plan to connect the Urban Master Plan and the Urban Management Plan of Seoul. It is also necessary to gradually expand the role of autonomous districts in urban planning and lay the foundation for the Seoul Metropolitan Government and autonomous districts to operate urban planning cooperatively.
