Taronga Zoo Wharf upgrade : review of environmental factors

Transport for NSW proposes to upgrade the Taronga Zoo wharf (the proposal) as part of the Transport Access Program (TAP) which includes both landside and waterside upgrade works. The water based features of the proposal would include: • Retention of most of the existing jetty and covered pontoon. However, to accommodate the new longer gangways the existing jetty structure and pontoon roof structure would be cut back by about 3.5 metres • Removal of existing gangways • Installation of two new covered aluminium 18 metre dual-lane gangways between the cut back jetty and pontoon. Each gangway would be held in place by two new piles (four in total) • Two new transition ramps on the existing pontoon to cater for the new gangways • Replacement of two of the existing jetty canopies to accommodate the change in jetty size • Construction of a new covered Disability Standards for Accessible Public Transport (DSAPT) compliant accessible ramp leading from the street level wharf entrance to the gangway entrances. The ramp would be held in place by nine new piles (three waterside and six landside) • Removal and relocation of the Transdev office and café on the existing jetty • Removal of the existing ferry arrestors on each side of the wharf to allow space for construction activities. Ferry arrestors would be replaced with two protection piles on each side of the wharf (four in total) • Changes to steel fencing on the pontoon to cater for changes in customer flows due to new gangways • Relocation of existing Opal Card readers and Opal top-up machine • Upgrade (where required) of safety and security features including lighting, closed circuit television (CCTV) security cameras, ladders to the water and tactile ground surface indicators, if required. The land based features of the proposal would include: • Regrading of the footpath and bus stop to achieve DSAPT compliance to the new accessible ramp • Retention of the five existing bicycle parking hoops • Retention of the public telephone booth • Removal of foreshore vegetation to construct the new accessible ramp. The proposal would be constructed over a duration of up to five months starting in late 2021. During construction the wharf would remain operational, however the adjacent café would be closed. Key features of the proposal are shown on Figure E-1.

新南威尔士州交通局（Transport for NSW）计划将塔龙加动物园码头升级项目（以下简称“本项目”）纳入交通通达计划（Transport Access Program, TAP），该计划涵盖陆侧与水侧升级工程。本项目的水侧工程内容包括：
• 保留现有栈桥及带顶棚浮码头的主体结构，但为适配新的更长渡轮通道栈桥，现有栈桥结构与浮桥顶棚结构需截除约3.5米。
• 拆除现有渡轮通道栈桥。
• 在截除后的栈桥与浮码头之间安装2座全新的带顶棚铝合金18米双车道渡轮通道栈桥，每座栈桥将由2根新桩（总计4根）固定。
• 现有浮码头增设2座过渡坡道，以适配新的通道栈桥。
• 更换2座现有栈桥顶棚，以适配栈桥尺寸变更。
• 新建一座符合《公共交通无障碍残疾标准》（Disability Standards for Accessible Public Transport, DSAPT）的带顶棚无障碍坡道，从街道层码头入口延伸至通道栈桥入口，该坡道将由9根新桩固定（3根位于水侧，6根位于陆侧）。
• 拆除并迁移现有栈桥上的Transdev办公室与咖啡厅。
• 拆除码头两侧现有渡轮止挡器，为施工腾出空间；后续将在码头两侧各增设2根防护桩（总计4根），以替代原有止挡器。
• 调整浮码头处的钢制围栏，以适配新通道栈桥带来的客流变化。
• 迁移现有奥宝卡（Opal Card）读卡器与奥宝卡充值机。
• 按需升级安全与安防设施，包括照明、闭路电视（closed circuit television, CCTV）安防摄像头、水上救生梯以及触感地面警示标识（如需）。

本项目的陆侧工程内容包括：
• 对人行道与公交站点进行重新平整，以符合新无障碍坡道的《公共交通无障碍残疾标准》要求。
• 保留现有5个自行车停放架。
• 保留公共电话亭。
• 移除岸滩植被，以施工新建无障碍坡道。

本项目工期最长为5个月，将于2021年下半年启动。施工期间码头将保持正常运营，但毗邻的咖啡厅将暂停营业。本项目的核心特征详见图E-1。
