rainwater tanks must be amended to include rainwater tanks/alternative water supply
for the commercial/hostel building fronting David Low Way.

All stormwater drainage (including roof water overflow from the rainwater storage
system) shall be collected and discharged so there is no net increase in stormwater
runoff from the site. Stormwater drainage permitted to drain from the site shall be
discharged via existing and proposed drainage structures contained within the site, as
detailed within the Simmonds Bristow report titled "Essence of Peregian Stormwater
Management Plan, Sediment and Erosion Control! Plan", dated 30 November 2009,
except as modified by these conditions. The maximum discharge of stormwater
drainage allowable to Council's kerb & channel street drainage system at any one
location is 25 litres/second.

A detailed Stormwater Management Plan and a Sediment and Erosion Control Plan
shall be prepared. This will generally be in accordance with Simmonds and Bristow
Report “Essence of Peregian Stormwater Management Plan, Sediment and Erosion
Control Plan’, dated 30 November 2009. MUSIC modelling and reporting shall be
refined to incorporate the final proposed design.

Grease and Oil arrestors and/ or stormwater quality improvement devices must be
incorporated into the design to treat all run-off prior to run-off exiting the premises
Grease and Oil arrestors or stormwater quality improvement devices must be
consistent with the design and water quality objective requirements specified within the
Essence of Peregian Stormwater Management Plan, Sediment and Erosion Control
Plan dated 30 November 2009.

A detailed maintenance plan shall be prepared for the proposed stormwater
management system, which shall be submitted to the Council for approval prior to
obtaining a Development Permit for Operational Works.

The approved maintenance plan shall be incorporated in the Community Management
Scheme for the development and a copy of this shall be provided for Council's records
prior to commencement of the approved Use.

A Development Permit for Building Works shall not be granted until a Development
Permit for Operational Works has been issued in regard to the drainage scheme.

The fill material (including topsoil) to be used within stormwater treatment areas (i.e.
including but not limited to stormwater infiltration swales and other areas as required by
the Simmonds and Bristow Plans) shall achieve a minimum infiltration rate of
75mm/hour without clogging. Sand is required to achieve this infiltration rate hence
clays and silts are not allowed as fill material. Specific infiltration and soils property
testing shall be carried out to demonstrate the suitability of proposed fill material. Such
testing shall be on the fill material prior to placement.

All habitable dwellings shall be located above the ARI 100 year flood level, which is set
at RL 3.5m for the site. The ARI 2 year event flood level is set at RL 3.0m AHD in
relation to regional flooding.

All site stormwater drainage shall be by means of a gravity system. In this respect, the
application for Operational Works Approval for Stormwater must be accompanied by a
stormwater drainage plan that demonstrates compliance with this condition.

Environmental Management Plan

71.

An Environmental Management Plan (EMP) for the Site shall be prepared and
implemented by persons holding appropriate environmental qualifications and proven
expertise in the preparation and implementation of EMPs, to ensure that the impact on
the environment of the construction and operation of the Development is minimised, the
Environmental Values of the Site are protected and enhanced and the Development is
ecologically sustainable.

The EMP shall be cognisant of the following:-
