Strategy and Planning Committee Agenda 16 February 2011 TIDAL PRISM Cardno have completed a Tidal Prism Review which is primarily based on existing studies which were undertaken at the time the original Pelican Waters canal system was proposed. The northern end of the Pumicestone Passage is a dynamic system with the location of sand banks within the passage and the location of the Caloundra Bar itself moving over time. This natural variation in the Pumicestone Passage has historically resulted in changes within the tidal prism within the Pumicestone Passage of 25%. In comparison the increase in tidal prim associated with both the existing and proposed waterways of Pelican Waters range from 3.6% to 5.6%. The combined effect of the existing and proposed waterways on tidal velocities at the Caloundra Bar would be 0.7% for the ebb tide and 0.55% for the flood tide. In reality the increase in tidal velocity will result in a slight increase in the cross sectional area of the channel and the increase in tidal velocity at Caloundra Bar would be negligible. The increase in tidal prism and tidal velocity at the entrance of Lamerough Canal will be of greater significance than at the Caloundra Bar. In addition, within the existing Lamerough Canal the channel is enforced so there can be no increase in cross sectional area and increased velocities will be realised. The increase in tidal prism will however not result in any scour impacts within the existing Lamerough Canal. In summary the effects on the Pumicestone Passage due to the increase in tidal prism resulting from the construction of the additional waterways would be almost negligible and would be masked by naturally occurring variations in the tidal dynamics of the Pumice Passage. CARRYING CAPACITY FOR WATER CRAFT Given the application seeks to include an 80 Wet Berth marina and a 200 Berth Boat Stacker, it is reasonable to suggest that as a result of the proposed land uses, the number of private boats utilising and recreating in the waters of Pumicestone Passage will increase. Vessel registration data obtained from Maritime Safety Queensland shows that at 30 April 2010, 8,132 vessels were registered in areas with convenient boating access to Pumicestone Passage. The natural increase of vessel registration is approximately 4.2% per annum. It is submitted by the applicant that it is estimated that the proposed development may increase the amount of vessel registrations with convenient access to Pumicestone Passage by between 5.5% and 7%. It is difficult to measure the actual increase of motor boat usage on the Pumicestone Passage. Council adopted the Waterways and Coastal Management Strategy that details major deliverables for natural waterways, of which the Pumicestone Passage Catchment is identified, include the development of Catchment and Estuary Management Plans and the establishment of marine zones. It is proposed to commence the development of a catchment and estuary management plan for the Pumicestone Passage in early 2011. This plan is intended to be a tool that will allow catchment and passage management issues to be identified and prioritised and suitable management actions (including costs and timelines) developed for priority issues. The plans will consider: Page 56
Strategy and Planning Committee Agenda 16 February 2011 • Social: The sustainable use of our waterway for both active and passive recreational and leisure activities and the protection of the cultural and creative significance of waterways; • Environment: Protection and improvement of waterway health by addressing diffuse and point sources of pollution, extent and condition of riparian vegetation, bank stability and aquatic fauna; and • Economic: Support for the maintenance and growth of waterway dependent tourism and commercial industries, including both on-river operations and businesses adjacent to waterways, which contribute to the Sunshine Coast economy. The draft Waterways and Coastal Management Strategy 2010 – 2020 recognises that population growth, and the associated increasing demand for recreational space on our estuaries, is a key challenge for waterways management. It identifies marine zones as the most appropriate tool for improving the management and regulation of the activities of recreational vessels on our estuaries because they complement existing marine regulations. At Council’s Ordinary Meeting held on 6 October 2010, a resolution was passed to commence the process for establishing marine zones for the Maroochy and Mooloolah River estuaries, and Pumicestone Passage, in parallel with the development of holistic management plans for these waterways. Marine zones restrict certain types of vessels or certain types of activities within specific areas of a waterway, and if required between certain times. Marine zones can be established by Queensland Transport, at the request of other government entities, to regulate on-river activity in order to minimise nuisance, noise and other amenity issues, address environmental impacts, improve safety and reduce conflict between users. It is estimated that the establishment of marine zones for these estuaries will take at least 2 years. Currently, there appears to be no justification for restricting or refusing the development of the marina and boat stacking facility. ACID SULPHATE SOILS Investigations have determined that acid sulfate soils are present on the site, and there are significant environmental risks associated with disturbing acid sulfate soils at this site. It is acknowledged that future applications will be required to prepare acid sulfate soil management plans prior to development occurring. For the purpose of this preliminary approval application the presence of acid sulfate soil on the site is considered to be manageable and does not represent a constraint to the overall development. Should this proposal be approved, it is recommended that a condition be included requiring the preparation of a detailed Acid Sulfate Soils investigation in accordance with the State Planning Policy SP2/02 and Queensland Acid Sulfate Soils Investigation Team Guidelines, which achieves the outcomes of SP2/02. A subsequent Acid Sulfate Soils Management Plan will be required to be submitted which outlines specific management in accordance with SPP2/02 and the Queensland Acid Sulfate Soil Technical Manual: Soil Management Guidelines. Further, the proposed Southern Lakes Pelican Waters Planning Area Code includes a note under section 2.1 that states: “All Assessment Tables, Other Development Assessment Tables and Overlay Assessment Tables identified in the Caloundra City Plan 2004 that are not changed by this preliminary approval, continue to have an effect over the land”.
