Q3-2 Is a rainwater regulating pond required for development permission?

Facilities that temporarily store rainwater include “reservoirs, etc.” due to the diameter of existing public sewers outside the development area, and “rainwater runoff control facilities” due to the presence or absence of river improvement at the discharge destination. There is. The former must be set up based on the criteria for development permission, and the latter must be set up based on the consent criteria based on the ordinance, but it is the installation area of "rainwater runoff control facilities" and the installation of "reservoirs etc." If you do, if you install one of the more storage facilities, it will conform to both standards.
