4. Provide detailed information on the operational and maintenance requirements
    of the lagoon/wave pool, including details such as:
   4.1. detailed plans for the lagoon/wave pool, including sections and cut and fill
        requirements;
   4.2. details on water supply / delivery, including how the water will be delivered,
        how the lagoon/wave pool will initially be filled, and how any additional
        water will be supplied if required;
   4.3. where the proposed water tanks will be located;
   4.4. how the wave is generated, including details on pumps, filtration system,
        how often the waves are generated etc;
   4.5. hours of operation;
   4.6. methods to be employed to ensure that the appearance and noise generated
        will not adversely impact on other residents or the locality, including a Noise
        Report, prepared by a suitably qualified person, addressing all aspects of
        the use;
   4.7. any proposed lighting, including height, location and lux levels;
   4.8. any proposed fencing, including height and location.

The design of the wave lagoon and associated pumps/blower concrete compound at the
end of the facility similar to the detailed plans shown in Appendix 3 for a similar designed
lagoon. The plans show the main noise emitting blowers and pumps will be located under
the hillslope within a concrete shell. Further detailed design work will be provided as part
of the subsequent Operational Works applications.

An Environmental Noise Level Impact Assessment has been undertaken by David Moore
& Associates and is included as Appendix 4. The report identifies the main noise sources
to be from the blowers used to generate the waves, pumps and people noise. The
conclusions of the report indicate that all steady state noise sources such as pumps and
blowers can be located within a concrete structure, as proposed at the end of the facility.
The report also describes that for the time varying noise source (people), the buffer
distances complies with the acoustic quality objectives for the proposed hours of operation
(0500 to 2200 hours daily), with no additional noise control measures required.

Details of the water supply and reticulation are included as Appendix 5 and seek for a 2
x 280,000L tank be installed adjacent to the pool. One of the tanks will include an unsealed
base for disposal of excess water via infiltration and one for storage for top up during dry
periods. The pool also includes 2m high sides to retain the proposed wave, allowing for
up to 2m of rainfall without the pool over topping. This represents almost an entire year of
rainfall for the 90th percentile wettest conditions.

At this stage, the applicant proposes to only use the facility during daytime hours and no
lighting is proposed. Normal pool fencing will surround the lagoon compliant with relevant
Building Act requirements and be integrated into the detailed landscaping design.
