The District Unit Plan is system that connects urban plan pursuing public benefits to architectural plan pursuing private profits. This plan uses a incentive system because it coordinates these reciprocal viewpoints. The incentive system of the District Unit Plan is inducement which gives the FAR when regulated items are set and those are allocated the definite FAR. Thus a reasonable management of the incentive system is needed to start the District Unit Plan effectively.
The incentive system of the District Unit Plan is divided into the permissible FAR and the Land Donation. However, the permissible FAR which is more useful to an owner df lands or buildings is provided according to the FAR. This restriction checks the use of the plan. First of all, if the area, the permissible FAR also can't be utilized because of restriction of the area, the permissible FAR also can't be available.Second, the BCR and easing to uses of buildings. In the case of above two reasons, an owner of lands are not interested in using the incentive system. Besides, it causes an obstruction of effective operation ofthe Dstrict Unit Plan. So the incentive system of the only FAR has a limit and it is not attractive to the owner. Cons quently, the variation of operation of this system is needed such as the way of easing the highest height and the BCR.
The goal of this research is to give quantitative grounds of the system and to draw a conclusion of the possibility of the system. For the goal, I deduce the impossible zone which is not available for the standard FAR because of deduced quantitative restrictions among problems of the incentive system that is only applied by the FAR.
The impossible zone of Mapogu, seoul is deduced using ARCMAP. Through the analysis, 793 pieces of the land which are occupied 1.45% of Mapogu are unavailable to apply the standard FAR. I present actual examples showing the limit of the incentive system of the only FAR. These examples are not available to upply the incentive system of the permissible FAR. Thus, I simulate these area using the BCR and the highest height incentive system to find out possibility of various operation of theincentive system. As the result of this simulation, 68.68% of these area is available to use the standard FAR. So, I draw a conclusion that it is useful to vary this FAR system utilizing the BCR and the way of easing the highest height. However, 31.32% of the land turn out the limit of the physical incentive. It means that the incentive system of the District Unit Plan is needed to introduce not only the incentive of the only FAR but also the BCR and the highest height incentive system. Furthermore, this conclusion shows that this system is necessary to utilize administrative and financial incentive system.
This reasearch proves that the various operation of the incentive system is needed on the quantitative grounds and shows the possibility of this system.
