Expansion and development of a city bring about demands for the new land and change of use and utilization efficiency for the existing land. The purpose of urban management plan is to manage the changes made in the city in a more organized and methodical manner. Based on these detailed planning, local government designates a site to plan and determines its unit plan. And based on the district unit plan, a joint development system is implemented in order to 1)maintain city aesthetics and secure a lot optimal for development, 2)secure a lot area equivalent to its development potential, 3)resolve issues of small lots (too small for any architectural construction) or irregular lots (rugged land with irregular form) generated in the process of new public facility and road construction and expansion, 4)ensure efficiency of land use. However, most of the joint development sites have not achieved their initial purpose of designation/recommendation due to individual civil complaints or delay and moreover, designation/recommendation for joint development are subject to private lands, limiting the local government’s role following the designation/recommendation. This research investigates joint development cases to examine the cause of development delay and proposes an improvement methods for the system based on the studies of each case. Whereas preceding research concerning the case have utilized numerical figures as an analysis tool such as increase rate in floor area ratio and connectivity to public transportation, form of the land, etc, this research focuses on identifying concrete causes of development delay through surveying the designation criteria, investigating present condition, checking related codes and capacity of each site.
Considering the special characteristics of the joint development, subject of investigation for this research were limited to sites with certain period of time past the designation/recommendation period, and 4 sites surrounding Cheonho Station in Gangdong district were selected thereof. Current condition and development status of each joint development designated/recommended sites were investigated on the basis of architecture register and land use plan, and sites developed following the designation/recommendation period and sites delayed since the joint designation/recommendation period were each selected for detailed investigation. Out of total 122 sites, 6 were jointly developed, 7 were partly developed, 1 was incomplete over a long period of time, and remaining sites were being delayed. 11 out of total 122 sites were investigated by utilizing cadastral survey data input using CAD(Computer Aided Design), and by checking related code and capacity, etc. As a result, it was found that there were some sites being developed in accordance with the original purpose and intent of the joint development, but most of the sites were being delayed due to lack of equity in implementation of the system, omitted present condition survey and detailed plan, and unreasonable designation grounds. This thesis proposes the following improvement methods based on the above research and in-depth interview.
Firstly, the servicing company (company providing a certain service for monetary gain) should submit the data from research and site investigation of joint development designated/recommended sites to the local government. Secondly, the servicing company should prepare detailed investigation report including designation criteria and development potential based on the survey and collected data. Thirdly, the local governments should assign separate personnel for comprehensive checking of related codes and reexamine the selection process of the servicing company. Fourthly, the local government should review diverse support policies. Fifthly, investigation concerning the maximum/minimum development capacity is required, and categorizing the floor area ratio and incentive by use according to its recommended use and allowed use is also necessary.
Designation/recommendation of joint development is implemented by the local government, but its feasibility and results are determined by individuals. Sites designated/recommended for certain purpose must be continuously managed to achieve its initial goals. Considering the fact that the investigated district is one of Seoul City’s 25 boroughs, a follow-up research is required so as to expand the subject sites to whole of Seoul City, and concerned official administration should review appropriate improvement method for the joint development system to keep progressing smoothly.
