You must manage rainwater runoff from the entire site, even if there is greenfield area within the project boundary. Note that the runoff volume of the chosen storm, under developed conditions, is what is required to be managed and documented, rather than the rainfall volume. All required runoff volume must be retained (infiltrated, reused, etc) within the project boundary.
