Court Order approved extension of currency 2013 · 132008.176

washing machine cold taps and toilet cisterns. All rainwater tanks are to be designed and
installed in accordance with the Queensland Development Code (QDC) current at the time of
building approval, and shall be part of the plumbing application for approval. The location
and capacity of the tanks shall be clearly shown on the plans submitted for Building
Works/Operational Works approval and any overflow shall be directed to the stormwater
drainage system.

58. A stormwater management plan and stormwater management design must be submitted to
Council for approval prior to obtaining a Development Permit for Operational Works. The
stormwater management pian and stormwater management design must be prepared by a
RPEQ, specialising in stormwater and water quality management incorporating the principles
of the relevant approved Management Plans as described in Decision Notice 23118 DA.
The stormwater management plan and stormwater management design must demonstrate
water reuse strategies, infrastructure capacity and effective treatment methodology. The
use of rainwater harvesting tanks for irrigation purposes shall be incorporated in the overall
design plans. The following information is required to be submitted with the stormwater
management plan and stormwater management design submitted with the application for
Operational Works Approval:

a. An Audit report which confirms that the stormwater design achieves all criteria and
actions specified in Elements D.1 of Settlers Cove Noosa Residential High Density
Environmental Management Plan by WBM dated 25 July 2007;

b. Confirmation from an RPEQ that the sites proposed stormwater management measures
will provide for infiltration into the sand subgrade without runoff for storms up to a 10
year Average Recurrence Interval;

The location for any required oil and sediment traps; &

MUSIC model results that demonstrate that the site will achieve the pollutant reduction
targets required by the Water Sensitive Urban Design Technical Design Guidelines and
the following water quality criteria:

i. Total nitrogen levels — 0.34 mg/l; &
ii. Total phosphorous levels — 0.035 mg/:

59. All stormwater drainage shall be collected on site and discharged so there is no net increase
in stormwater runoff from the site.

60. To ensure that polluted run-off does not enter the water table, the adjoining waterways or
Council's stormwater drainage system, stormwater run-off from the car parking areas and
the driveways shall have the first flush (the first 12 mm of rainfall or hose-down) collected in
a grease/oil arrestor/gross pollutant trap provided on site prior to being permitted to
discharge into the larger drainage system.

All other clean stormwater, such as roof water, can be collected on site and discharged
through a single underground drain line directly into the existing drainage system, bypassing
the grease/oil arrestor/gross pollutant trap.

To this ehd, a detailed maintenance plan shall be prepared for the proposed grease/oil
arrestors/gross pollutant trap, 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.

61. 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.

62. All site stormwater drainage shail be by means of a gravity system.
