Perth Region Garden Bore Suitability Boundaries

A spatial dataset from the Department of Water and Environmental Regulation delineates areas suitable or unsuitable for new garden bores in the Perth region. It was updated in response to the 2010-11 dry season, integrating factors like salinity levels, proximity to wetlands, and soil characteristics. The data is recommended for display at scales of 1:10,000 or larger.

Use Cases

• Classify land parcels as suitable/unsuitable for garden bores based on proximity to conservation wetlands and salinity thresholds.
• Analyze groundwater sustainability risks by overlaying bore suitability boundaries with areas of existing over-allocation.
• Model potential acid sulfate soil development or unreliable clay soil supply using the designated unsuitable area polygons.

Strengths

• Data integrates multiple regulatory and environmental factors including salinity, wetlands, soil types, and groundwater abstraction.
• Boundaries are aligned with property lines and roads for practical application.
• Maintained by the authoritative state Department of Water and Environmental Regulation.

Limitations

• No row or feature count is provided, making scale and granularity unclear.
• Designed for display purposes only at specific scales, limiting analytical precision.
• Based on conditions from a 2010-11 event and subsequent analysis, potentially not reflecting current hydrology.
