Strategy and Planning Committee Agenda 16 February 2011 Issues The cumulative impact of the development of Pelican Waters Southern Lakes, Bellvista 2 and Caloundra South on the Passage has not been explored. Comments The development site forms part of the lower Lamerough Creek Catchment. The site does not discharge to Bells Creek. The receiving waters for Lamerough Creek in the Pumicestone Passage downstream of Bells Creek. The Pumicestone Passage & Bribie Island are identified as significant coastal wetlands under pressure from development on land and activities on the water. The cumulative impacts of development within the catchment are two fold. First, the risk land based development poses to water quality within the passage. Second, the pressure that additional populations place on the Passage for recreational activities. The risk that land based development poses to water quality objectives within the Passage can be managed through the development and implementation of two key strategies: 1. Urban water quality management strategy; and 2. Lake and Tidal Waterway management strategy The urban water quality management strategy involves a fully integrated system of stormwater quality improvement devices that regulate the quality of major flows to the legal point of discharge, being the proposed lake. The lake does not form part of the treatment train, although some treatment is inevitable, hence the water quality objectives for the lake are the same as the Environmental Protection (Water) Policy 2009, water quality objectives for the Pumicestone Passage. The lake and tidal waterway management plans establish minimum water quality standards, require on-going monitoring, identify emergency procedures for problems and requires rectification and solutions if any problems do occur. The implementation of these strategies work together to minimise the risk of adverse environmental harm as a result of this development. These strategies do not eliminate the risk of adverse environmental harm, however these strategies significantly reduce the likelihood of an event occurring, the extent of harm is an event occurs and significantly improve Council’s ability to respond to an event. These strategies when developed will need to consider the cumulative affect of established development with the catchment. To measure the potential cumulative impact, including Caloundra South at this stage would be impossible because of the lack of density, design and engineering detail available on Caloundra South. Concerns are raised as to the extent of The subject land is envisaged to be developed pursuant to the Caloundra City Plan 2004. Filling will be conducted in Page 70
Strategy and Planning Committee Agenda 16 February 2011 filling. Issues Filling of flood prone land is in contrary to Council’s Growth Management Position Paper. The proposal conflicts with State Planning Policy 1/03 which requires that filling of a floodplain only occurs where there is an overriding need for the development in the public interest and no other site is suitable and reasonable available. Comments accordance with Caloundra City Plan 2004 and associated policies. Overland flow paths will be conditioned so that the development does not result in the ponding of stormwater within existing residential areas surrounding the proposed development. Besides the areas of man made channels on the subject site no filling of land below the peak 100 year Average Return Interval freshwater flood level in Bells Creek is proposed. Filling of land below the current 100 year Average Return Interval storm tide level is proposed. Filling of land subject to storm tide inundation is treated differently to filling of land associated with freshwater flooding. When dealing with freshwater flooding any filling of land in the floodplain results in displacement of floodwaters which has associated impacts. With storm tide flooding the inundation is caused by raised sea levels due to the low pressure and wind action over the ocean. Filling of land subject to storm tide inundation does not cause an increase in storm tide levels elsewhere. Therefore it is recommended that filling of land subject to storm tide flooding but not regional freshwater flooding be accepted. This interpretation of SPP 1/03 differs from that of Council. SPP 1/03 does not state that filling of floodplains only occurs where there is an overriding need for the development in the public interest and no other site is suitable and reasonable available. Rather the SPP states that within the floodplain that development is compatible with the nature of the hazard. The development has been assessed as being compatible with the nature of the hazard. Besides the areas of man made channels on the subject site no filling of land below the peak 100 year Average Return Interval freshwater flood level in Bells Creek is proposed. Filling of land below the current 100 year Average Return Interval storm tide level is proposed.

Filling of land subject to storm tide inundation does not cause an increase in storm tide levels elsewhere. Therefore it is recommended that filling of land subject to storm tide flooding but not regional freshwater flooding be accepted. Page 71
