LATE RFI - Response Letter from Recor

                4. Include the requirements of the Sustainable Building Code (water tanks) within
                   the SMP
            Please refer to the update Stormwater Management Plan. The requirements of the
            Sustainable Building Code have now been incorporated through the requirement that
            future dwellings upon the proposed lot will require a minimum 3,000L rainwater reuse
            tank, which has also been reflected in the updated drawings.



                    5. Provide additional comment on the impacts on the downstream property
                       of the concentrated discharge and the impacts on the future development
                       potential of the adjoining land

            The flow from the upstream properties which is diverted around the site will now be
            dispersed through a level spreader device of nominally 4m to ensure that the flows
            are discharged as sheet flows towards the downstream property. This will ensure
            minimal impacts the downstream property and future development thereupon. As the
            change in peak run-off from the development is negligible, the proposed
            development will remain consistent with the existing peak flows therefore no
            worsening of conditions to the downstream properties will arise. Refer to updated
            stormwater management plan for details and drawings 010 and 040 respectively that
            reflect the changes.

                    6. Indicate on the plans any necessary easements required to convey runoff from
                       external to the site and within the proposed new lots.

            A dedicated drainage easement extending from shared access and services easement
            has been provided to convey runoff from upstream or external sources to the
            proposed development site. Proposed Lot Configuration plan 010 has been updated
            to reflect this.

            Existing Access

                    7. Provide additional comment from the engineer in regard to the condition of the
                       existing driveway and its ability to cater for the additional traffic movements

            The existing driveway is a concrete domestic residential driveway of approximately
            3m. A site visit was undertaken in September 2022 which found that there were no
            significant issues nor presence of extensive cracking beyond typical ageing that would
            impact upon the service life of the driveway were present as shown below.

                                       Figure 1 – Existing Shared Concrete Driveway

            The anticipated traffic loads and heavy vehicle movements are not significantly altered
            from existing conditions once construction traffic has ceased, with the addition of a
            single new dwelling resulting in a potential 7.4 additional trips per day, or 0.78
            additional peak hour movements in accordance with the RTA Guide to Traffic
            Generating Development Updated Traffic Surveys (2013).
            As an existing driveway which currently caters for similar traffic demands, the
            additional traffic volume is not considered to be an excessive demand that would
            compromise functionality of the access.

                    8. Provide a concept plan of the proposed driveway and its connection to the
                       existing driveway.

            The plan has been updated to indicate the proposed driveway and connection to the
            existing access driveway.

                    9. Provide swept path plans at the junction of the existing and proposed driveway.
                       The swept paths must be for a B99 vehicle as described in AS/NZS2890.1:2004
                       and the vehicle types that can be reasonably expected to utilise the driveway
                       for construction purposes (eg building material deliveries, concrete truck etc)

            A plan of the swept paths has been provided as plan 060 Swept Paths. The plans show
            a B99 vehicle is able to enter and exit from the proposed driveway. An MRV vehicle
            has been used as an indicative construction vehicle to demonstrate the extent of the
            expected swept paths for these vehicles. Construction traffic will be able to enter and
            exit the site however on departing the travelled path will extend beyond the concrete
            driveway. Any damage to the adjacent grasses surface or driveway would be repaired
            at the closeout of construction.
