Proposed Subdivision
1 George Tewantin




    corner of the site is 3.65m deep but has now been located more than 15m from the
    large tree in front of lot 1 and as such is not anticipated to impact on this tree. The
    sewer main then traverses the rear of lots 1, 4, 5, 7, 10 and 11 to service these lots
    and two manholes connect to sewer pipes along the side boundary of lots 2 and 8
    to provide a connection to the rear of lots 2, 3, 6, 8 & 9. The proposed sewer system
    has been forwarded to Unitywater for initial comment and they have no objection in
    principle to the proposed alignment.

    The sewer connects to the existing network on the north side of George St. It is
    proposed to tunnel bore under the existing George St pavement and new footpath
    at this location. This will also assist in minimising damage to two existing trees on
    the south side of the road. The alignment of the sewer on the south side of George
    St in front of number 35 is 1.75m off the property boundary. There are a few
    significant trees within number 35 but these are set back between 3 and 5 metres
    from the boundary and are unlikely to be impacted upon by the installation of the
    new sewer. If necessary arborist services will be engaged to undertake minor root
    pruning during excavation for this section of the sewer and to provide advice on
    protection of any other trees potentially impacted on by the sewer construction.

    In order to avoid disturbance of significant trees at the George Street frontage the
    development site the water service to each block has been positioned accordingly.
    Two road crossings (tunnel bores) are proposed to avoid trenching in front of a large
    tree in the front of proposed lot 1 and lot 10. Note a similar approach is proposed
    for the underground electrical service.

    The above information is provided in support of the response to Council’s
    information request dated 9 July 2015.
