RFI - Stormwater Management Plan

Lots 10 and 11 are proposed to be amalgamated as part of the development.

Refer detail survey at Appendix F.



3.0    PROPOSED DEVELOPMENT

The proposed development consists of multi storey hotel buildings with
basement carparking underneath and all buildings to be surrounded by
extensive landscape areas, both hard and soft.

Guests’ vehicular entry to basements will be from Banksia Avenue while
service vehicles will access back of house areas via the cul-de-sac bowl at the
end of Serenity Close.

Revised architectural layouts will not require the existing concrete footpath at
the eastern end of Serenity Close to be extended westwards and hence the
existing grassed swale may be reinstated at completion of sewer realignment
works.




4.0    STORMWATER TREATMENT & DISPOSAL – DEVELOPMENT
       SITE

Treatment and disposal of runoff from the subject site will be carried out in
accordance with the approved document Settlers Cove Noosa Residential High
Density (RHD) Environmental Management Plan (EMP 1) by WBM Oceanics
Australia.

Alta Projects Engineers (formally TATE) were involved in formulation of the
overarching development approval document and EMP1 produced by WBM
Oceanics.

EMP1 recognises in particular the regimes of stormwater runoff and
infiltration which existed over the broader RHD site pre-development.

Essentially it was recognised that the RHD site lies atop a dune of poorly
graded sand with particularly high rainfall infiltration rates. As such the
natural state sees rainfall infiltrate the dune close to where it lands and
replenish the water table below with little or no runoff.
