      owner's responsibility and independent from each other. Typically in this situation the new allotments could be
      serviced by an E2 pump well with a 50mm poly line discharging into either a common discharge manhole or
      alternately the Council existing manhole may need to be lined or equivalent system acceptable to Council.


            3.3.   Storm water Drainage

      The site falls from Webb Road or the top northerly corner from roughly, RL 50m, to the southern beach side at,
      RL 42.5m. Webb Road falls away from the property's entrance, with the local catchment discharging into a gully
      on Webb Road into a piped drainage system that ultimately outlets onto the beach at Ed Webb Park.

      A pathway reserve is located along the southern property boundary, with pit and pipe roofwater drainage
      located near the bottom proportion of this pathway. A small roofwater pit that services the subject and
      neighboring properties was noted, with this system discharging into a natural gully at the southern corner of the
      site.

      It is recommended that the current outlet position be maintained. Consequently, roofwater pits and pipe along
      the rear boundary of the proposed new allotments covered by easement, if required by Council is proposed.
      This piped drainage would then also discharge into the existing outlet, which is currently protected by gabion
      mattresses which transitions the flow into the natural gully. The existing protection is expected to be adequate
      for the increased flow. No siltation or erosion issues are expected.

      In conclusion, based on the investigations undertaken the proposed new allotments can be adequately serviced.
      Though the use of a common services trench both water and sewerage service can be provided. With the
      provision of private individual sewerage pump stations. Roofwater can be provided along the rear boundary,
      and discharged so as to maintain existing outlet conditions.
