Split decision

Core Reason for the Refused Part

The proposed dwelling is located within Flood Zone B, where highly vulnerable residential development is not permitted under the Strategic Flood Risk Assessment and Policy IE4 Objective 1 of the South Dublin County Development Plan 2022-2028.

Decision Maker's Conclusion

  • The development is classified as highly vulnerable and is situated within Flood Zone B, which precludes residential development under the current County Development Plan and Strategic Flood Risk Assessment.

  • The proposal does not comply with corner/side garden development standards, specifically failing to provide sufficient passive surveillance and failing to maintain the required 3-meter setback from a public foul sewer line.
