The language is somewhat confusing but identified growth areas are those areas subject to FURTHER INVESTIGATION before they are included in the urban footprint. See p 107 - 109 on Identified Growth Areas
IGAs are shown indicatively on this map. They will be subject to further review before their boundaries are finalised and the Minister considers them for inclusion as a Development Area.
IGAs - Table 7 identifies areas outside the urban footprint which, subject to further investigations, may accommodate growth beyond 2031. The long-term viability of urban development of IGAs will be protected by retaining IGAs within the Regional Landscape and Rural Production Area to limit further development and fragmentation within the life of the plan. Urban development within an IGA before 2031 will only occur in exceptional circumstances , subject to achieving compliance with Urban footprint principles and relevant investigations contained within the subregional narratives . Any further consideration of an IGA for urban development will also take into account proximity to existing and planned urban infrastrucuture networks and associated costs of expanding the network to accommodate growth in the IGA, and achieving a compact urban settlement pattern in the region."

" The North Naclean Identified Growth Area comprises land outside the Urban Footprint, adjacent to the Mt LIndesay Highway ,south of Gieseman park, east of Greenbank Rd and north of the Logan River. Further investigations will determine the area's cadastral boundaries before it can be considered for urban use. "
"Subject to further investigations, this area could accommodate an enterprise precinct with office, commercial, warehouse, retail services and low - impact industrial uses. This use depends on responding to biodiversity values and physical constraints ,and compliance with the remaining urban footprint principles ( Principle 8.2)"
