Document controls Approval and authorisation Title Berowra Waters Ferry Ramp Upgrade review of environmental factors Accepted on behalf of NSW Joshua Lewis Roads and Maritime Services Project Manager by: Signed: Dated: Executive summary The proposal The car ferry at Berowra Waters provides access between Berowra, Berowra Waters and Berrilee, in the far northern suburbs of Sydney. It is maintained and operated by Roads and Maritime Services NSW (Roads and Maritime). Roads and Maritime proposes to upgrade the ferry ramps at Berowra Waters with precast concrete panels for the sections below the tide level and poured in situ ramp sections above the high water mark. Need for the proposal The proposal is required to maintain a safe ingress and egress for pedestrians and vehicles approaching the ferry. Maintenance inspections indicate the existing ferry ramps are showing signs of degradation that could pose a safety hazard for pedestrians and vehicles. Without a safe operating ferry at Berowra Waters motorist travelling between Berrilee and Berowra would be required to detour via Galston, a detour of about 19 kilometres. Motorists travelling south on the Pacific Highway (M1) to Berowra Waters (west) or Berrilee would be required to travel through Asquith, a detour of about 16 kilometres Proposal objectives and development criteria The objectives of the proposal include: • To maintain safe ferry ramps to/from the Berowra Waters Ferry for vehicles and pedestrians • To maintain access between the eastern and western sides of Berowra Waters • To minimise the likelihood of ongoing maintenance requiring closures • Minimise the environmental impact, including social impact. Options considered Four options were identified and assessed against the proposal objectives. The options include: Option 1. Do nothing Option 2. Repair the existing ferry ramps Option 3. Remove existing ferry ramps and construct new ferry ramps Option 4. Construct new ferry ramps over the existing ferry ramps Option 4 is the preferred option as it is the only option that meets all of the proposal objectives. This option would construct safe ferry ramps for pedestrians and motorists, minimise the likelihood of ongoing maintenance, reduce construction time thereby minimising ferry closure periods during construction and minimise environmental harm. Statutory and planning framework State Environmental Planning Policy (Infrastructure) 2007 (ISEPP) aims to facilitate the effective delivery of infrastructure across the State. Clause 94 of ISEPP permits development on any land for the purpose of a road or road infrastructure facilities to be carried out by or on behalf of a public authority without consent. The proposal is categorised as development for the purpose of a road infrastructure facility and development for the purpose of associated public transport facilities for a public ferry and is being carried out by or on behalf of a public authority. With the implementation of State Environmental Planning Policy (Infrastructure) (ISEPP) the proposal is permissible without consent. The proposal is not State significant infrastructure or State significant development. It can be assessed under Division 5.1 of the Environmental Planning and Assessment Act 1979. Development consent from council is not required. Berowra Waters Ferry Ramp Upgrade i Review of Environmental Factors Roads and Maritime is the determining authority for the proposal. This Review of Environmental Factors (REF) fulfils Roads and Maritime’s obligation under Section 5.5 of the EP&A Act to examine and take into account to the fullest extent possible all matters affecting or likely to affect the environment by reason of the activity. Community and stakeholder consultation A Community and Stakeholder Engagement Plan (CSEP) (Appendix F) has been prepared for the proposal. The plan aims to describe the communication and consultation approach and activities for the project and advise stakeholders and the community on the outcome of the consultation. Notification letters and community updates were undertaken during strategic design development in mid- November 2016. Continued community involvement, including display of this REF, would be undertaken. No government agency or stakeholder involvement has been undertaken for the proposal. However, as outlined in the CSEP, early notification to government agencies, local businesses and residents, and other stakeholders would be undertaken. Future consultation with the Berowra Waters Marina would be undertaken regarding the use of four vehicle and trailer parks for an ancillary facility. Environmental impact The proposal as described in the REF best meets the proposal objectives but would still result in some impact to traffic, socio-economic, waterways, water quality and noise. The ferry would be closed during construction. A detour would be required and while trip times may not be impacted due to time spent waiting for the ferry, travel distances would be increased. Local businesses, particularly those that depend on passing trade, have potential to be impacted by a four to six week ferry closure. Some minor sediment disturbance may occur during installation, dewatering and removal of the coffer dam, placement of rip rap and installation of the precast concrete panels. The concrete panels would be transported by barge and some work would be undertaken by barge within Berowra Creek. The pouring of concrete for the ferry ramp above the tide level and cutting concrete is a source of potential pollution to water quality in Berowra Creek. Accidental spills from construction plant such as the water pump, crane, concrete agitator/vibrator or from the compound site have the potential to degrade water quality. Particularly risky activities would include the refuelling of any construction plant, especially the water pump. Impact to waterways and water quality would be minimised by the safeguards and management measures included in section 6.1.3. Some noise sensitive receivers near the proposal would be highly noise affected during construction, particularly when concrete saws would be in use. However, the noise impact would be limited to standard working hours and the impact would be minimised by the safeguards and management measures included in section 6.2.5. Justification and conclusion The proposal is required to maintain a safe ingress and egress for pedestrians and vehicles approaching the ferry. The safeguards and mitigation measures included in the environmental assessment (refer to section 6) would minimise any risk to the environment.
