NA82013034 Cardno November 2015 Prepared for Lend Lease ii Transport Assessment Executive Summary Cardno has been engaged by Lend Lease to prepare a Transport Assessment for the Bingara Gorge Residential Development. This reporting has specifically been prepared in relation to the Land and Environment Court proceedings 10554 of 2015. The report addresses the traffic and transport items raised in the Wollondilly Shire Council Statement of Facts and Contentions document, included at Appendix A. The subject of this Transport Assessment and the above mentioned appeal proceedings relates to the proposed increase in the Bingara Gorge residential yield to 1,800 dwellings from the already approved 1,165 dwellings. The subject yield change only relates the residential component of the existing Bingara Gorge development. At the October 20th 2015 Section 34 conference, Cardno entered into discussions with the Craig McLaren of McClaren Traffic Engineering who is acting as the opposing traffic expert on behalf of Wollondilly Shire Council. Subsequent to the October 20th conclave discussions, a technical approach and assessment scope was developed jointly between Cardno and McLaren Traffic Engineering. In response to the Wollondilly Shire Council SOFC and the conclave discussions, Cardno has reassessed a selection of the primary analysis assumptions and developed a new SATURN mesoscopic model that is representative of the Bingara Gorge development and the adjacent road network at the 2036 time horizon. The model has been used to quantify and assess the internal and external traffic demands and operations for the already approved 1,165 dwelling scenario in addition to the proposed 1,800 dwelling scenario. The SATURN traffic demand estimations include two-way link demands for each of the internal development road sections as well as intersection turning movements. The turning movements have been used as inputs to the supplementary SIDRA assessment of the key internal and external traffic intersections to confirm traffic operations and upgrading requirements. The SIDRA analysis confirms that engineering solutions are possible at the external Picton Road intersections of Pembroke Parade and Almond Street. The analysis confirms that both intersections will ultimately require signalisation irrespective of the Bingara Gorge residential yield scenario. The internal development intersections have also been assessed as operating well within typically adopted performance thresholds for both yield scenarios. Ongoing discussions are recommended relating to the timing and funding of the external intersection solutions. As would be expected, the SATURN assessment confirms that the proposed yield expansion will result in an increase in traffic demands on many of the major internal road connections. The daily traffic demands output from the model indicate key development connections including Pembroke Parade, Oxenbridge Avenue, Greenbridge Drive, and Fairway Drive will cater for traffic demands that are at the upper range of the broader planning thresholds typically published by a selection of Australian planning and approvals authorities. Cardno suggests that the demands may be considered reasonable based on consideration of: > The traffic assumptions adopted as part of the SATURN modelling exercise are conservative, especially at the 2036 time horizon where the car mode share is projected to be lower given improved public transport and nearby external employment and retail development > The majority (86-87%) of the proposed 1,800 residential dwellings do not have any frontage to internal development roads which have been modelled as carrying more than 1,500 vpd. This figure is comparable or higher than that referenced in the RMS Guide to Traffic Generating Developments (Section 7.3) > Each of the critical internal road sections include separate provision for kerbside or indented car parking, thereby ensuring the full-time provision for two general traffic lanes > The density of direct residential frontage access on the critical road sections is relatively low > Road reserves are relatively wide and include pathway provisions for pedestrians and cyclists > The already constructed residential dwellings on critical internal sections have been located such that they are set-back 12-25m from the edge of the kerb. These larger than typical set- back characteristics will likely reduce any acoustic or amenity impact resulting from the modelled increase in traffic demand.
