Q1-3 Is the division of the site a development activity?

It is not a development activity if it is just a site split, such as a shared brush on a public map, but it may be a development activity if cut or embankment is accompanied.
In addition, we have established and operated interpretation standards for "development activities" and "development areas", so please bring documents such as drawings and consult directly with the person in charge of permission.
