A number of GIS layers were provided by Council to assist with the study. This included: • Aerial Photography – provides 2014 ortho-rectified aerial imagery at a 0.5 metre pixel size; • Cadastre – provides property boundary polygons; • Stormwater Pipes – Provides alignments, lengths and diameters of stormwater pipes; • Stormwater Pits – Provides locations and types of stormwater pits/inlets; • Road Centrelines – Provides locations and names of roadways within the study area Each allotment within the catchment was assigned an ERP classification for the 20% AEP, 5% AEP, 1% AEP and PMF. This was completed using the TUFLOW model results, digital elevation model and a road network GIS layer.
