This is indicative flood mapping identifying 1 in 100yr overland flow paths and flood corridors outside the catchment wide flood study hydraulic models.
<DIV STYLE="text-align:Left;"><P STYLE="text-align:Justify;margin:0 0 0 0;"><SPAN><SPAN>Central Coast Council contracted Worley Parsons to create a 1 in 100yr flood surface covering the LGA, outside the catchment areas of the adopted flood studies. This was done for each of the former Gosford and Wyong LGAs. The GridFlow model essentially determined flowpaths across the surface of the DEM provided by Council.</SPAN></SPAN></P><P /><P STYLE="text-align:Justify;margin:0 0 0 0;"><SPAN>It is important to note that GridFlow surfaces should be considered as indicative only and are not recommended for setting strict planning constraints such as minimum floor levels.</SPAN></P></DIV>
