Underpinning around Fairy Meadow
The state's soil-landscape map returned the Gwynneville unit at three of our five sample points in Fairy Meadow and the Fairy Meadow unit at two. The report for the Fairy Meadow unit lists its limitations as flood hazard, low wet bearing strength, highly permeable soils and high seasonal watertables, and says these soils are generally stable. It names Fairy Meadow first among examples of the lowlands and floodplains associated with the unit, and says the unit is not capable of urban development in areas subject to water logging or flooding, and otherwise moderate.
That is the opposite of the reactive-subsoil wording in the reports for some hill-foot units. It is still a map at coarse scale from a 1990 survey, and two of five points is not the suburb. It does not say any house here is flooded, wet or moving. What it suggests is that a provider looking at a Fairy Meadow floor should ask about water first, and about the level of the water table.
Permits and Wollongong City Council rules
Wollongong Local Environmental Plan 2009 clause 7.5 requires consent for works on land the acid sulfate soils map puts in a class: any works in Class 1, works below the natural ground surface in Class 2, works more than one metre below it in Class 3, more than two metres in Class 4, and, in Class 5, works within five hundred metres of adjacent Class 1 to 4 land that are likely to lower the water table there. The state's planning layer shows Classes 1, 3, 4 and 5 intersecting Fairy Meadow. The clause exempts works that disturb under a tonne of soil, foundations among its examples, or that are not likely to lower the water table. Whether a footing job does either is a fact about the job, and the class on a given lot is for the council to say.
