this recognised ecosystem had been taken into account in the setting of
buffer distances and location of the stockpiling facilities.
The predominant soil type has been identified as gravelly sand and vegetation growth consists of native
bush which transitions into pasture. Average annual rainfall for the site is 1,942 mm (taken from the nearby
‘Stratford’ monitoring station).
The stockpiling facility located at Surrey Road is operated under one consent (7559-1.4). This consent allows
and associated actions to minimise or prevent damage by floods and river erosion.
In 2018/2019, all flood control schemes will be maintained to the 1 in 100 year levels of protection or to the
standard set in the relevant asset management plan for minor schemes. Rainfall and river levels will be
monitored and timely flood warnings issued.

Average annual rainfall for the site is 1043 mm (taken from the nearby Patea
monitoring stations). As with the other South Taranaki coastal sites, the Vanner site is
subject to strong winds predominantly from the N-NW at average speeds of 10-20
