The district units plan is one of the urban management plans established by combining urban designs and detailed plans as a positive regulation to escape from negative regulations that the use region system has. Besides, this is limited to a specific region in terms of its application scope rather than aiming at the entire city differently from other urban management plans, and is supposed to present a positive guide for the development behaviors that take place on the individual land rather than staying at a negative regulation for development behaviors.
District units plans, however, should be promoted by being connected with various urban development projects and urban improvement projects over the private parts and public parts, but actually many problems are currently being caused with the operation of district units plans.
Therefore, this study aims to compare the district situation at the time of being designated as a district units plan region with the situation after the district units plan is operated by selecting sample regions after passing a certain period after the district units plan are established and to present data for activating future district units plan by grasping whether the planning elements are executed in public parts and private parts.
The contents investigated and analyzed based on such objective of research can be largely divided into the problem regarding execution of planning elements, the problem regarding the reference floor area ratio, the problem regarding incentive, etc. and can be summarized as follows.
First, this is the problem regarding execution of planning elements at the district units plan region.
Sample regions of this study were designated as detailed planning regions in the late 1990s and the district units plan has been executed. However, the comparison and analysis results between the situation at the time of designating the district and the current situation show that it has been insufficient whether the planning elements have been executed even though 10 years have passed. It shows that the private development to determine the building development density such as building line withdrawal, recommended use, open notice, common building, board size, etc. as well as the public development corresponding to the urban infrastructure such as road increase, park installation, parking lot installation, etc. in the sample district is also very insufficiently being executed. Therefore, in order to activate the private development in the district, it is thought to be necessary to induce the private development naturally by the district self-governing community positively investing in the securement of urban infrastructure as well as expanding budgets for the public development.
Secondly, this is the problem regarding the reference floor area ratio in the district units plans.
Currently the district units plans prescribes that upward adjustment of use region is prohibited. Besides, reference floor area ratio should be set lower than allowable floor area ratio, and it is regulated that allowable floor area ratio should not exceed the legal floor area ratio prescribed by the laws regarding the national land planning and use. Moreover, it is appearing to be the biggest problem to prescribe that reference floor area ratio should not exceed the allowable floor area ratio even if incentive is applied.
In case of sample regions, it is prescribed that reference floor area ratio should not exceed 230% and allowable floor area ratio 250% in the third kind of general residence district, and the range of such allowable floor area ratio also includes additional floor area ratio pursuant to the incentive. Due to such downward application of reference floor area ratio, questions from district residents are rising and development desire is lowering.
Accordingly, in order to solve such problems, it is necessary to prepare a systematic device to promote private development. It is thought that more active private development may be induced if a regulation to mitigate the floor area ratio is prepared by applying legal floor area ratio designated by the laws regarding national land planning and use in terms of reference floor area ratio and by applying excess of reference floor area ratio according to the execution of incentive for the district units plans in terms of allowable floor area ratio.
Thirdly, this is the problem regarding incentive of district units plans.
It is thought that currently the problem regarding incentive in the district units plan is lack of consistency, fairness, and flexibility. This is appearing as another cause of reducing private development because practical effects of floor area ratio mitigation pursuant to incentive application is reduced as well as legal floor area ratio is not exceeded even though incentive is actually applied.
Accordingly, it is thought that it is necessary to prepare a systematic supplementation to enhance the practical effects of application guide level for the incentive along with application scope of reference floor area ratio and to effectively and reasonably connect the regulation means related to development density such as floor area ratio, building height, building coverage ratio, etc.
The district units plan is a plan to induce private development as well as a gradual urban management plan. Therefore, in order to activate the district units plan, it is necessary to review continuity and affirmativeness more positively. It is necessary to present a realistic guide to grasp the execution situation of district units plans by more deeply analyzing the situation of district units plan region that has been planned and applied up to now and to focus on the realization possibility and actuation of systems by analyzing the problems occurring during application of district units plan guide at present.
