Main issues, as the Inspector framed them
- Whether the proposed extension would accommodate flood resilience measures and would be at risk of flooding
What decided it
The absence of sufficient evidence that the extension accommodates the required flood resilience measures and the resulting risk of flooding in a flood zone 2 location.
The private benefit of supporting a growing family was of limited weight and could not outweigh the identified policy conflict regarding flood risk; the neutral factor of complementary character could not overcome the flood risk harm.
What the Inspector cited
- Development plan policies
- SI 12SI 13CP28CP29DMD59DMD60
- National Planning Policy Framework
- Paragraph 167Paragraph 168
