This study was conducted to define the concepts of artificial ground, superstructure of artificial ground, and amenities for residents, which constitute new facilities integrated in Haengbok [happiness] Pubic Rental Housing(HPRH) districts, as public facilities and to analyze their functions and roles on the basis of facility supply situations in the Gajwa-Oryoo pilot HPRH district. By so doing, it was intended to present a rationale for the stance that public entities, such as municipalities, have the right to and duty of operational management of these facilities. Taking into account facility types, such as artificial ground, superstructure of artificial ground, and amenities for residents, locations of facility installation (asset type), and ownership, the operational management system was classified into 8 types, and the anticipated problems, key issues, and pros and cons of each type were analyzed and presented as guidelines for persons in charge when the public facility operational management becomes an actual issue. By analyzing similar national and international cases and weighing up pros and cons of each of 8 types, system revision plan necessary for a stable and sustainable operational management of a Haengbok housing district is proposed. Also proposed are a system for setting up partitioned superficies in public land as a basis for artificial ground management and superstructure construction, applications of spatial decision and duplicated decision on urban planning facilities, a cost sharing plan for the budget by equity and operational management budget, operational management methods differentiated in accordance with the nature of amenities for residents and introduction methods, and finally an operational management methodology model for each facility type.
