Other Change Decision Notice - Council Meeting Decision 132007 2446 05 · 132007.2446.05

                        directed to the road frontage/the stormwater drainage system/etc located in Pacific
                        Avenue.
                 26.    All stormwater drainage (including roof water overflow from the rainwater storage
                        system) shall be collected and discharged so there is no net increase in stormwater
                        runoff from the site. Stormwater drainage permitted to drain from the site shall be
                        discharged into Council’s existing drainage structure (drainage pit at the frontage of the
                        site in Pacific Avenue). Plans of the drainage design shall be prepared by a Registered
                        Professional Civil Engineer and submitted to Council prior to obtaining a Development
                        Permit for Operational Works.
                 27.    The applicant shall ensure that the development will not adversely impact on the
                        drainage conditions on other properties. As the there will be significant filling and a
                        potential for obstruction to the natural stormwater runoff from adjoining properties, where
                        applicable appropriate stormwater drainage pipes shall be installed within the site to
                        collect and discharge stormwater runoff from adjoining properties to prevent additional
                        ponding/flooding on other properties or diversion of stormwater runoff onto other
                        properties. A Development Permit for Operational Works shall be required.
                 28.    To ensure that polluted run-off does not enter Council’s stormwater drainage system,
                        stormwater run-off from the carparking areas and the driveways shall have the first flush
                        (the first 12 mm of rainfall or hose-down) collected in a grease/oil arrestor/gross pollutant
                        trap provided on site prior to being permitted to discharge into Council’s drainage
                        system.
                        All other clean stormwater, such as roof water, can be collected on site and discharged
                        through a single underground drain line directly into the existing drainage system,
                        bypassing the grease/oil arrestor/gross pollutant trap. To this end, a detailed
                        maintenance plan shall be prepared for the proposed grease/oil arrestors/gross pollutant
                        trap, which shall be submitted to the Council for approval prior to obtaining a
                        Development Permit for Operational Works.
                        The approved maintenance plan shall be incorporated in the on going maintenance
                        scheme for the development and a copy of this shall be provided for Council’s records
                        prior to commencement of the approved Use. A Development Permit for Building Works
                        shall not be granted until a Development Permit for Operational Works has been issued
                        in regard to the drainage scheme.
                 29.    All site stormwater drainage shall be by means of a gravity system.
                        Sewer Mains
                 30.    The site shall be connected to Council’s existing sewerage reticulation systems and be
                        constructed in accordance with Council’s standards and requirements at no cost to
                        Council.
                 31.    The existing sewer main that traverses the site and the sewer main that runs in the
                        adjoining property at the rear of the site and the ‘zone of influence’ (taken as the area
                        within a 45-degree angle measured from the invert of the sewer main to the finished
                        surface level) shall be accurately located and determined by a licensed Surveyor and
                        shown on all plans submitted for Operational Works approval.
                        To ensure Council’s sewer main is accessible for maintenance purposes and is
                        protected from risk of damage no structures requiring a building permit (eg. buildings,
                        swimming pools, retaining walls exceeding 1m in height, raised terraces, etc) shall be
                        constructed within this ‘zone of influence’ or within 1.5m of the centreline of the sewer
                        main, whichever is the greater. As such the applicant shall amend Operational Works
                        plans including Building plans to ensure compliance.
                        Service Easements (Sewer)
                 32.    A registered easement shall be created over the zone of influence of all sewers within
                        the subject site and over those parts of the subject site that are impacted upon by sewers
                        on any adjoining sites. The easements shall generally be parallel to and centred over
                                                                                                           Page 5 of 24
