Our previous study showed the standard of the performance for an urban improvement plan from the view point of the prevention from urban fire spread, using the percolation models to which we extended the model leading the standard with Fireproof Area Rate that the urban planners often use. However, our previous study had one problem that our result can be applied to the only infinite urbanized area although the actual urbanized area is finite. In this paper, we modifies the standard of the performance for urban improvement, plan and shows the new method to apply to a given finite size area, using the finite size scaling hypothesis based on percolation theory.
