Core Refusal Reason
The primary concern relates to significant pluvial flood risk and the potential for the development to increase flood risk elsewhere by impacting flood water flow paths, coupled with an inadequate Flood Risk Assessment that failed to account for extreme weather events.
Decision Maker's Conclusion

- The proposal fails to demonstrate appropriate surface water containment at the entrance and lacks confirmation that site finishes will maintain the necessary permeability to mitigate runoff.
