Core Refusal Reason
Insufficient information to demonstrate that the existing surface water drainage system has the capacity to accommodate the proposed development in accordance with current standards, specifically regarding climate change allowances and flood risk management.
Decision Maker's Conclusion
- The applicant failed to provide sufficient engineering evidence to prove the surface water system can accommodate the additional load while meeting current Greater Dublin Strategic Drainage Study (GDSDS) standards.
- The drainage modeling omitted necessary allowances for climate change, which is a mandatory requirement for all new developments to ensure long-term infrastructure sustainability.
- The lack of demonstrated capacity poses a risk of increased discharge into the river, potentially exacerbating downstream flooding and prejudicing public health, contrary to national flood risk management guidelines.
