MCU14/0056 Information Request

                                                                                    MCU14/0056



Information Required
37     Label the nominated sizes for each basin on the drawings and ensure adequate
       footprint is included on the design to include the required filter media area plus
       sediment forebays plus 1:4 batters around the edges of the basins and maintenance
       access points. Also propose estimated inlet and outlet levels for the stormwater
       drainage to and from each biobasin.

Issue – Basin Discharge
It appears that waters treated in the service station bioretention basin will also enter the self
storage biobasin, or vice versa. There is concern that some waters will unnecessarily be
retreated/impede the treatment capacity of the recieving basin. The outlet point is unknown.

Information Required
38     Please demonstrate that discharge from the self-storage area bioretention basin will
       have a legal point of discharge and will not be retreated or overload another
       proposed bioretention basin.

ACOUSTICS

Issue – Acoustic Assessment
A number of aspects of the submitted Acoustic Assessment require clarification or
additional detail.

Information Required
39     Provide an amended Acoustic Assessment addressing the following:

       (a)     Provide further information about the traffic noise model, including the extent
               of the model, ground absorption co-efficient, buildings included, grid spacing
               for noise contour plots.
       (b)     Re-plotting of the traffic noise levels contours showing 60 dBA L10 (18 hour)
               scale and increments of 1 dB.
       (c)     Provide further information to demonstrate that the proposed park cabin
               design may satisfy the MP4.4 noise criteria for a 6.0m high boundary
               acoustic barrier.
       (d)     Provide information to demonstrate compliance for the whole pool area with
               the passive recreation noise criterion.
       (e)     Conduct testing to determine a representative caravan outside-to-inside field
               transmission loss with natural ventilation, and then determine a suitable
               external façade corrected noise criterion based upon the recommended
               mobile accommodation noise criteria noted in Section 2.1.1 above.
       (f)     Provide further information to demonstrate that the mobile accommodation
               will comply with the determined façade corrected noise criterion.
       (g)     Provide an assessment of sleep disturbance due to road traffic for the park
               cabins and mobile accommodation areas, based upon the sleep disturbance
               criterion of Section 2.1.1 above.
       (h)     Provide an assessment of the noise impact of commercial uses upon the
               tourist park accommodation during the day, evening and night periods.
       (i)     Review and confirm the applicable noise criteria levels in Tables 5.3 and 5.4
               of the acoustic report.
       (j)     Provide a detailed description of the noise model used to assess the impact
               of the commercial uses, including source locations, buildings included, car
               wash roof, receptor locations.
