NOOSA COUNCIL IDAS Development Application Decision Notice                                                   31 of 51


195.   Sediment and erosion control plans shall be prepared in conjunction with the Sediment and Erosion
       Control Management Plan, to the reasonable satisfaction of the Manager – Land Development and in
       accordance with the Institution of Engineers Australia ‘Engineering Guidelines for Queensland Soil and
       Sediment Control’ (June 1996) and in particular using Checklist No. 3 from that document. The sediment
       and erosion control plans shall cover all stages of the resort development (during the construction,
       establishment and operational phases) including rehabilitation and remediation of the resort site. These
       plans are to be submitted to Council in conjunction with Operational Works application.

196.   Sediment basins and their batters and outlets for the site shall be located outside the 10 metre setback to
       the intermittent creek and with ARI 5 year piping to the intermittent creek.

197.   The Developer shall not commence any development on the resort site until the Sediment and Erosion
       Control Plan is approved by the Manager – Land Development.

198.   The Developer shall not commence any development on the resort site until the staged sediment and
       erosion control is in place as indicated in the approved staged sediment and erosion control plans.

199.   The Developer may amend the Sediment and Erosion Control Management Plan only with the prior
       written approval of the Manager – Land Development, which is not to be unreasonably withheld.

200.   The staged sediment and erosion control plans must have regard to the objective of minimising the
       transport of nutrients and sediment from the Site and providing pollution control measures which deliver
       an acceptable level of safety and health risks for the owner and occupiers of Lot 27 and the environment
       on Lot 27.

201.   Sediment runoff from site disturbance during revegetation is to be monitored and localised effects are to
       be mitigated by use of a range of techniques including;

       201.1. additional mulching;

       201.2. spraying of disturbed areas with chemical binders or soil stabilisers;

       201.3. placement of jute mesh and other protective coatings on disturbed areas; and

       201.4. use of sediment fences down slope of revegetated areas.

202.   The Development is not to restrict the natural flow of water in the southern intermittent creek running from
       the Site into Lot 27 or adversely affect its quality.

203.   The Development is not to cause flooding from the southern intermittent creek onto Lot 27 or erosion of
       the bed or banks of the intermittent creek.
Stormwater Management
204.   All stormwater drainage shall be collected on site and discharged so there is no worsening off-site during
       critical events. That is there shall be no net increase in the peak stormwater flows from all events, being
       Q1 to Q100 critical design events. Stormwater drainage permitted to drain from the site shall be
       discharged to the intermittent creek to protected outlets to ensure no scour occurs. Stormwater drainage
       shall be designed in accordance with Water Sensitive Design Principles and stormwater flows shall be
       dispersed as much as possible, without increasing risks of scour to the riparian buffer or creek.

205.   Roof runoff from any of the villas and other central buildings shall be directed to a rainwater storage
       system or tank (minimum storage 3000 litres per villa and for other uses minimum storage calculated
                        2
       using 12 litres/m of roof area) that is installed to ensure water from the tank can be used for external
       uses (such as watering gardens, irrigation, ornamental ponds, water features, topping-up swimming pools,
       outdoor cleaning, etc) and for use in flushing of toilets internal to the dwellings and buildings.   All
       rainwater tanks are to be designed and installed in accordance with the Queensland Development Code
       (QDC), Part 25 – Rainwater Tanks, and shall be part of the plumbing application in conjunction with the
       building approval. The location and capacity of the tanks shall be clearly shown on the plans submitted
       for Building Works approval and any overflow shall be directed to the stormwater drainage system.

206.   The applicant shall submit an analysis of water supply reliability for internal reuse of collected rainwater on
       the site with an application for Plumbing Works. This shall assess the requirements for dual plumbing to
       enable rainwater to be used for toilet flushing.
