HD6: Basement Building
The following criteria shall guide decisions for basement development:
- In Flood Zone 3a no habitable uses shall be permitted at basement level. All basements must have a safe access/egress route with a ‘very low’ hazard rating from the development to an area wholly outside of the 1 in 100 year event with an appropriate allowance for climate change;
- Basement development must not cause a significant rise to the existing water table or impede groundwater flows that would prejudice the safety of neighbouring properties;
- Applications for basement development must demonstrate there will be no detrimental impacts on the rates of drainage in the event of floods;
- Basement development must be protected from sewer flooding through the installation of a suitable (positively) pumped device where a waste outlet is present. Applicants must show the location of the device on the drawings submitted with the planning application; and
- Pumping of groundwater into the sewer network should be avoided.
