With the increasing interest among modern people in the environment and leisure activities, the social demand for parks and green spaces is increasing. Thus, with the increase in park consumers, it is necessary to systematically investigate and analyze user characteristics and demands and continuously reflect them in park management to increase user satisfaction. Therefore, this study focused on Central Park in Dongtan 1 New Town, Hwaseong City, to analyze and evaluate what variables affect users’ behavior and satisfaction and suggested ways to construct future neighborhood parks. After theoretical considerations, the site was investigated and analyzed, and user behavior and satisfaction were studied through surveys and in-depth interviews. The results showed that user satisfaction with the Central Park was generally high, and the park had a large positive effect on the satisfaction with the residential environment among residents. It seems that the psychological and mental satisfaction provided by the park, which relieves mental and physical stress in modern people’s busy lives and supports static and dynamic recreational activities, will be high. It was judged that if user demands are more actively reflected upon, user satisfaction can be increased, and parks can be vitalized.
