In response to the 2010-11 dry season, the Department of Water and Environmental Regulation updated the areas suitable/unsuitable for additional garden bores in the Perth region. Areas designated unsuitable for additional garden bores have included the following factors: • salinity levels likely to be 1500 mg/L TDS or greater (in some instances >1000 mg/L TDS) because of proximity to river or ocean; • proximity to conservation wetlands (EPP 2004, Conservation, and Resource Enhancement); • potential for unreliable supply to clay soils (Guildford Clay); • areas of thin superficial formations underlain by Rockingham Sand and/or Leederville Formation; and • potential for development of acid sulphate soils. • current Gnangara Mound groundwater abstraction risk map plus buffers around wetlands recommended for protection in the Gnangara Sustainability Strategy. • areas over allocated to existing users and where additional garden bores could present a sustainability risk to the groundwater. The boundary between suitable/unsuitable areas for additional garden bores has been plotted according to the above factors and then modified to best fit of property boundaries and roads. It is recommended the data be used at or above a scale of 1:10,000 for display only. This dataset was formerly known as Garden Bore Suitability (DOW-061)
