The study discusses how traditional urban planning focused on housing needs for growing populations, leading to issues with disconnected city plans. To address this, Seoul introduced neighborhood plans under the city's master plan, involving residents and local government in planning at a community level. These neighborhood plans aim to balance city-wide and local needs, promoting resident participation in urban development. To improve these plans, legal frameworks and functions need to be established, aligning with government policies for community-based planning. Ultimately, neighborhood plans have the potential to enhance urban planning by reflecting residents' needs and fostering community involvement.
