1856 - Partial Response to Information Request - Barlow Shelley OPW20-0145 · OPW20/0145

    ·   Bollards to the perimeter of the swale and Bioretention basin in Road A have been
        removed in favour of a barrier kerb with regular cut-outs. The upright barrier kerb is
        reinforced with a concrete kerb backing strip to limit damage from wheel contact.
    ·   Batter grades are amended with proposed extended detention depths to ensure the
        ponding depth in street tree pits and basins remains below the kerb invert line. Therefore,
        minor design storm kerb flow width/depth criteria in QUDM is a function of the bioretention
        overflow pit level and calculations are consistent with those provided on Drawings 1856-
        SW16-SW18
    ·   Street Tree pits are not proposed to be grated and shall function effectively and
        bioretention basins with WSUD species street trees for the subdivision works. Future
        development of Lot 3 and 7 on private Road C may require these to be grated with a future
        pedestrian application to the verge. The grates and restructure of the street tree basin
        surfaces would occur at this time when there is clear information on the end use of the
        road verges.

Item 36
If device sizes or extended detention depths are altered then provide an updated SWMP and
MUSIC modelling which demonstrates that the pollutant load reduction targets are met.

Response
Please refer to the below MUSIC model results screenshots and the attached MUSIC file to
demonstrate compliance with the NSC planning scheme and Qld SPP (2017) for water quality
outcomes in the proposed subdivision development.

Item 37
Provide an amended preliminary Construction Management Plan that addresses Council’s
concerns.

Response
Please refer to updated Construction Management Plan enclosed with this response. Traffic
control and regular site vehicles are still proposed to enter the construction site from the existing
constructed end of Hofmann Drive. Vehicle parking and site offices will be located on Proposed
Lot 4 as per the submitted TGS documents. Heavy construction vehicles and deliveries shall enter
the construction site from the existing roundabout stub on Walter Hay Drive.
