construct dwelling house, wastewater treatment unit and percolation area

Refused

Core Refusal Reason

The development was refused due to its significant negative visual impact on a prominent hillside, traffic safety hazards arising from substandard road access, and public health risks related to unsuitable soil for wastewater treatment.

Decision Maker's Conclusion

  • The proposed dwelling would be located on an elevated and steeply sloping site requiring extensive excavation and clearance, resulting in a visually prominent development that would be seriously injurious to the landscape character and visual amenity of the area.
  • The access via a substandard private road and its junction with the R309 regional road is considered inadequate to cater for additional traffic, posing a hazard to road users and setting an undesirable precedent for similar developments in the vicinity.
  • Site investigations revealed high groundwater levels and poor soil percolation properties, meaning the site is unsuitable for the safe disposal of domestic effluent, thereby posing a significant risk to public health.
