Justification and Amplification: Material Selection for Permeable Surfaces (Section 2.23)
When assessing permeable surface treatments in new residential developments, the Department will use a flexible approach to material acceptability provided the surface is suitable to its location, high quality, and visually attractive and appropriate to the overall scheme design.
There is an ever increasing choice of materials available which are designed specifically to allow water to infiltrate to the ground or to be collected for re-use. Accordingly, when assessing proposals for permeable surface treatments within new residential developments the Department will operate a flexible approach to the acceptability of materials provided the resulting surface treatment is:
• suitable to its location;
• high quality; and
• visually attractive and appropriate to the overall scheme design.
