Permeability
The SuDS Manual (C753) published by CIRIA in 2015, defines permeability as:
‘A measure of the ease with which a fluid can flow through a porous medium. It depends on the physical properties of the medium, for example grain size, porosity and pore shape.

- Air permeability.
- Air permeability in isolation rooms.
- Air permeability testing.
- Low permeability cut-off walls.
- Infiltration.
- Permeable pavement.
- Pervious area.
- Slowly permeable layer.
- Vapour permeability.
Bradford City Centre Design Guide, Supplementary Planning Document, published in 2006, suggests that permeability is: 'The ease with which people can move around an urban area. A permeable neighbourhood has plenty of streets and it is possible to move through the area by a variety of routes.'
Urban Design Guidelines for Victoria, published by The State of Victoria Department of Environment, Land, Water and Planning in 2017, suggest that permeability is: ‘The extent to which the urban structure permits, or restricts, movement of people or vehicles through an area, and the capacity of the area network to carry people or vehicles.’
