Water quality credits clarification - KBCN1283

Crit 10 under the 'Water Quality' section states: 'The water quality credits are only available where at least 3 credits are sought in the comprehensive route.' Where it says 'sought' above, this should be interpreted as 'achieved'. Therefore the 'water quality' credits can only be awarded where 3 credits have been achieved in the comprehensive route.

Watercourse pollution from indoor parking - KBCN0545

If the design team can demonstrate that there will be absolutely no run-off from the indoor parking then the intent of the credit will be met. However, such proof would also have to demonstrate that no hydrocarbon spillage from vehicles found its way into the watercourse/sewer. It is likely that there would be water ingress from outside or that internal parking areas would have drains fitted and be cleaned regularly. In such conditions, the criteria are still applicable. The intent of this criteria is to ensure no hydrocarbons run off to any watercourse.
