What the evidence says
The submitted NIS describes green/blue roofs on each apartment block and the creche, permeable paving in drives and parking areas, a central-green soakaway, rain butts, tree pits, bioretention areas, rain gardens, three vegetated detention basins, silt traps and hydrocarbon interceptors.
Why it may matter — interpretation
Interpretation: identifies roof, paving, landscape and drainage packages that must be coordinated across the residential development.

Construction stores require impermeable bases and 110% bunding
Proposed in application · Construction-phase pollution controls in this submitted NIS
What the evidence says
The submitted NIS specifies chemical, fuel and oil stores on impermeable bases within a bund of 110% of storage capacity. It also specifies a 30 m separation from surface waterbodies for equipment, materials and chemicals, with spill kits, drip trays and designated refuelling areas.
Why it may matter — interpretation
Interpretation: identifies containment and site-establishment requirements.
What is not established
These are proposed mitigation measures, not evidence that a compound has been built or compliance verified. They do not describe a permanent fuel installation or an approved supplier.
