Dear Matt,
This letter is to address the council request for information items 1, 2 and 3 on application MCU22/0086,
dated the 6th June, 2022. The council queries and responses are detailed below.
1.   Provide additional detail on the access driveway. The detail must be prepared by a suitably qualified
     person (RPEQ – Registered Professional Engineer of Queensland) and include, but not be limited to:
     a.   A design that gives consideration to the Landslide Hazard Overlay and the ongoing stability of the
          site; GHD’s design as shown on drawings 12592247-C001 to C103 has adopted findings and
          recommendations presented in the CGC slope stability assessment report “CGC-SR-2022-011-
          R02-Rev01”. This report found that there was “a low risk of instability due to landslip actions” and
          provided recommendations in Section 6 which have been adopted throughout the design.
     b.   widths, levels and grades of the access driveway; Refer to drawings 12592247-C001 to C103
     c.   a longitudinal section extending from the centre of the formation in Black Pinch Road to the
          carport pad Refer to drawings 12592247-C001 to C103
     d.   Provide sufficient detail to demonstrate that a vehicle (B99 as described in AS/NZS2890.1:2004)
          will not bottom out or scape at any point throughout the driveway; Driveway crossover vertical
          geometry has been designed as per council standard drawing RS-056 which has suitable vertical
          clearances for the B99 vehicle. Refer to figure below for vertical clearance check at the crossover.
