Matters Arising
The impacts of recent extreme rainfall in the Gisborne region and the discharge of
forestry slash to rivers was raised and a discussion held over the likelihood of this
being
Rainfall patterns and intensity, and their influence on fluvial and cliff sediment supply;
and
• Geomorphology and geological make up of the coast.
The rate of erosion of sea cliffs in particular, depends on the following factors (Lumsden,
1995):
• Available wave energy producing both impact and abrasion (this can be altered by
refraction and diffraction of waves from reefs and off-shore bathymetry);
• The presence of absence of a protective beach at the base of the cliffs and type of

water from an approximately 136 km2 catchment that originates near the summit of Mount
Taranaki.
The climate is generally mild, with relatively high humidity and fairly high, evenly
distributed annual rainfall - with a catchment-wide annual rainfall of approximately 3,500
mm. The soils are typically volcanic, and include deep ash soils and well-drained alluvial
soils along the rivers. Slopes within the catchment range from gently undulating to
strongly rolling.
The
system and gentle rolling
topography make its lower extents exceptionally well suited to intensive agriculture. Here the average herd
size is larger meaning that farming is more intensive than in the other FMUs. The frequent, and often
intense rainfall events that occur on Taranaki Maunga erode the river banks and carry runoff from the
surrounding land. This results in rivers and streams that are muddy and brown for a few days following each
event.

risk of this happening again.
The maximum rainfall (43 mm/hr) used in
the application by Remediation (NZ) may be
a bit light.
This has been reviewed by the applicant in
their application.
The site needed to be tidied up generally.
The untidiness does not given them
confidence that it is being managed
appropriately.
Management plans and improved detail in
job descriptions for site and management
staff are intended to address this, along with
better recording of
district council’s
trade waste officer to see if you can pump it to the
sewer.
Make a reliable staff member responsible for managing
inspection and drainage of outdoor bunds.
Roofing – a simple solution
Roofing your bunds avoids human error and dispenses
with the need for stormwater valves altogether.
Further benefits include:
• Stopping rainfall coming into contact with
contaminants and washing them into the stormwater
system
• Preventing accidents from valves being left open
is 10 L/s. However as a result of stormwater inputs to the pond, the discharge
rate from the pond to the Mangorei Stream will be highly variable as it is dependent on weather conditions.
The size of the pond will allow storage for a 10% annual exceedance event (AEP) event. The maximum
discharge rate from the pond during large rainfall events is 1,060 L/s as this is dictated by the size of the
