             Lawful Point of Discharge
      As outlined by the Queensland Urban Drainage Manual (4th Edition – Institute of Public Works
      Engineering Australasia, Queensland Division) a test can be undertaken to determine
      whether a lawful point of discharge exists:
      The criteria for determining the lawful point of discharge are:
      (i)     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).

      It is proposed that discharge of runoff from the proposed development site will be
      maintained to the property boundary within the mapped waterway.
      It is considered that discharge from the site will be managed in such a manner as to not
      substantially damage third party property, and as a result it is considered suitable lawful
      points of discharge has been identified and achieved.
