figure of 43mm of rainfall per hour will be utilised. This is a very
consen/ative figure as values for the top 30 occurrences range from 8.0 to 15mm with the
average being 9.4mm (refer Table 2)
Runoff of the falling rain will be influenced by the site's runoff coefficient. This has been
calculated to be 0.7. Remediation (NZ) Ltd considers this coefficient to be a conservative
runoff coefficient as the papa base provides a very high degree of impermeability.
