Main issues, as the Inspector framed them
- whether the proposal constitutes permitted development under Schedule 2, Part 3, Class R of the Town and Country Planning (General Permitted Development) (England) Order 2015
- if the proposal is found to constitute permitted development, whether prior approval would be required and should be granted, with particular regard to flooding risks on the site
What decided it
The proposed drainage mitigation (permeable paving with perforated pipe) constitutes development requiring separate planning permission, and without certainty of its delivery, prior approval cannot be granted as the proposal would fail to satisfy the flooding risk condition under Class R.
