                Note: Some authorities may not accept a written approval from a current land owner
                because a subsequent purchaser will not be bound by the previous owner’s letter or
                contract (refer to Section 3.10).

If the proposed development maintains pre-development flow conditions, the lawful point of discharge
for the subject site is the existing inter-allotment stormwater drainage infrastructure within Lots 102,
107, and 108 SP 106085 and Starboard Avenue, east of the site, the Eumundi Noosa Road kerb and
channel and the Headland Drive stormwater drainage within. The proposed lawful point of discharge is
considered to be compliant with the criteria outlined in QUDM 2017 see below: -

         1.     The proposed development stormwater discharge will not alter the existing site’s
                stormwater discharge characteristics.
         2.     The location of the proposed discharge point is under the lawful control of the local
                government.
         3.     Authority to discharge over affected properties will not be required as the proposed
                development will discharge as per existing drainage conditions.




5.0      STORMWATER QUALITY


In the absence of adequate controls, urban development can increase both stormwater runoff volumes
and peak discharge rates. In addition, this urban development has the potential for increased creek
erosion and the stressing of in-stream aquatic ecosystems. The use of stormwater detention or retention
systems aims at reducing these threats by limiting property flooding to acceptable levels and also
filtering stormwater runoff through a vegetated soils media layer, thus reducing the threats caused by
urban development.

The following factors have been identified as potential contributors which can adversely affect
stormwater quality draining from the site:-

         •      Silt and sediment erosion
         •      Gross Pollutants
         •      Hydrocarbon runoff
         •      Nutrient runoff
