2.3           Lawful Point of Discharge
The Queensland Urban Drainage Manual (QUDM) (4th Edition – Institute of Public Works Engineering Australasia, Queensland Division)
identifies that a test can be undertaken to determine whether a lawful point of discharge exists:

The criteria for determining the lawful point of discharge are:

•    Will the proposed development alter the site’s stormwater discharge characteristics in a manner that may substantially damage a third-
     party property (see Section 3.6)?
          •    If not, then no further steps are required to obtain tenure for a lawful point of discharge (assuming any previous circumstances
               and changes were lawful).

The existing stormwater outlet has been relocated approximately 130m to the south-west of the existing outlet, with the discharge location
remaining in NSC Reserve, which is considered the sites lawful point of discharge.
