A do-something scenario reporting the change in operational noise due to the existing noise plus the future development of other committed transport projects in the city centre including the proposal. Operational noise impacts are affected by a number of factors: Traffic speed Traffic volumes and composition (eg the percentage of heavy vehicles) Number of traffic lanes resulting in traffic passing closer to sensitive receivers Reduced kerb extension and footpath width bringing traffic closer to sensitive receiver The height of the receiver relative to ground level and the reverberant effects along roads flanked by high-rise buildings. The proposal would affect all the above factors with the exception of traffic speed and traffic composition, which is not anticipated to change. With regard to traffic volumes, the assessment used the largest predicted changes introduced under the capacity improvements (refer to Attachment C of Appendix D). The assessment also accounted for the locations where the road configuration layout would be altered to increase the number of traffic lanes on the approach to or exit from an intersection. In some locations new traffic lanes would be created by time-restricting kerbside allocations and creating no-stopping zones at certain times of the day. The assessment assumed the lanes would be permanently created in all instances. The assessment therefore adopted a worst case approach, assuming traffic would pass closer to sensitive receivers for more of the time that it would do in reality. To account for the reverberant noise effects described above 1 dB was added to the noise results as described further in Appendix D. Table 6-19 reports the predicted change in road traffic noise between the ‘do nothing’ and ‘do something’ scenarios, with predictions based on changes in traffic volumes and lane arrangements. Table 6-19 Predicted change in operational road traffic noise due to proposal Work site Precinct 1: north-west Predicted change in road traffic noise level (dB) Day Night NW1: Kent Street 0 to 0.4 0 to 0.4 NW2: King Street 0 to 1.1 0 to 1.1 Precinct 2: retail R1: Park Street 0.5 0.5 R2: Market Street 1 to 2 1 to 2 R3: Sussex Street 0 0 R4: Clarence Street 0.4 to 1.4 0.4 to 1.4 R5: York Street 0 0 Sydney City Centre Capacity Improvement 225 Review of Environmental Factors
Work site Precinct 3: southern Predicted change in road traffic noise level (dB) Day Night S1: Sussex Street 0.1 0.1 S2: Goulburn Street 0.4 to 1.4 0.4 to 1.4 S3: Pitt Street 0.4 to 1.4 0.4 to 1.4 S4: Ultimo Road 0 0 S5: Broadway 0 to 1 0 to 1 S6: Pitt Street 0 0 to 0.1 Precinct 4: college C1: Wentworth Avenue 0.5 to 1.6 0.5 to 2.3 C2: College Street 0.6 to 1.6 0.6 to 1.6 Precinct 5: financial F1: Macquarie Street 0.2 0.2 F2: Macquarie Street 0 0 Table 6-19 shows that the proposal would marginally increase operational road traffic noise. Generally however the changes would be imperceptible as they would be less the 2 dB criterion described in section 6.2.2. However, one road section at Wentworth Avenue (work site: C1) shows a marginal predicted exceedance of the 2 dB incremental change noise criterion for the night-time period. As noted above, the modelled predictions represent a worst-case scenario as they have assumed the maximum increase in traffic volumes and that any created additional traffic lanes would operate full-time. In reality however traffic would be allowed to park along much of the kerb on Wentworth Avenue (work site: C1) at night; therefore this predicted increase is very conservative and is not likely to result in a perceptible increase in traffic noise at this location. Operational vibration No additional operational vibration sources would be introduced through the proposal. As such, there would be a neutral impact once the proposal is operational. 6.2.5 Safeguards and management measures Table 6-20 lists the noise and vibration safeguards and management measures that would be implemented to account for the potential impacts identified above in section 6.2.4.
