Why You Need This Survey in Avalon
Northern Beaches Council requires contour surveys for sloping sites, bushfire survey plans showing vegetation and asset protection zones, and flood certificates for low-lying properties Detail surveys are required for most DAs in Avalon, providing architects and designers with accurate site information. The sloping terrain requires detailed level information for drainage design and cut-and-fill calculations. Flood-affected properties require accurate levels to AHD for flood certificates.
Avalon Site Conditions
Terrain
