                 Stormwater Drainage
                 52.    The site must be provided with a stormwater drainage system connecting to a lawful
                        point f discharge. The works must be undertaken in accordance with an Operational
                        Works approval and must include in particular:
                        a.      the works shown on drawing number 17699-SK101 Revision A prepared by TOD
                                Engineers and Project Managers dated 17 August 2018, with the inclusion of the
                                following:
                                i.     The storage tank must have sufficient capacity to cater for the runoff from
                                       the driveway in a 5 minute 1%AEP rain event as a minimum.
                                ii.    The basement structures (walls, floors and surfacing) must be constructed
                                       of materials suitable for the potential inundation and all service connections
                                       must be located a minimum of 300mm above the potential inundation level.
                 Acid Sulfate Soils
                 53.    All works must be carried out in accordance with an Acid Sulfate Soil and Groundwater
                        Management Plan for the development prepared by a qualified person* and referenced
                        in a Development Permit for Operational Works. The Acid Sulfate Soil and Groundwater
                        Management Plan must specifically address how lowering of the groundwater level as a
                        result of the works will be avoided.
                        *(Refer to Advisory Note)
                 54.    All waters, including stormwater runoff, groundwater seepage and leachate from acid
                        sulfate soils must achieve the following quality prior to release from the site:
                        a.    a pH range of 6.5-8.5 pH units
                        b.    50mg/L maximum total suspended solids concentration
                        c.    0.3mg/L maximum total iron concentration
                        d.    0.2mg/L maximum total aluminium concentration
                        e.    no visible plume at either the point of release from the site or within a waterway
                 55.    The basement must be designed and constructed as a water excluding structure in
                        accordance with Australian Standard AS3735 "Concrete Structures for Retaining
                        Liquids" to ensure groundwater does not enter the basement after construction is
                        completed.
                 56.    All treated material must undergo verification testing at the rate of one sample per
                        250m3 throughout the duration of the excavation phase of the development. The
                        verification testing must be undertaken by a qualified person* using the SPOCAS or
                        Chromium Reducible Sulphur testing suite, and the results must be submitted to
                        Council for appraisal.
                 Electricity and Telecommunication Services
                 57.    Unless otherwise stipulated by telecommunications legislation at the time of
                        construction, the development must be provided with all necessary conduits, pits and
                        pipes to accommodate the future connection of optic fibre technology
                        telecommunications.
                 58.    Certification must be submitted to Council from all relevant service providers which
                        certifies that the development has met the requirements of this Decision Notice and all
                        applicable legislation at the time of construction.
