Keep of flood protection infrastructure protecting the Henley
township is one of the issues the Otago Regional Council is
investigating at the request of residents.
Community members recently met council chief executive Peter
Bodeker and engineers in the township to show them their
concerns about maintenance of infrastructure and the way
''We were highlighting observations from the last flood and
the previous one three years ago,'' Henley resident and
business owner Jay McLean said.
The group would now ''wait and see'' what solutions the
council offered, he said.
Council engineering and natural hazards director Gavin Palmer
said residents accepted the flood risk but were keen to find
out what could be done to improve the flow of water out of
the township after a flood.
It had been flooded about four times in the past seven years
and each time it raised issues, he said.
The area was affected by flooding from the Taieri River and
from water running off hills behind the township.
There were concerns about the maintenance of culvert outfalls
and the council had agreed to look at its maintenance
schedule to see if it could give residents more certainty, he
Some of the culvert pipe flaps which prevented the river
running back into the township could possibly be modified to
be more effective.
The profile of the low-level flood bank, which ran parallel
to the river and protected the town, was uneven so the
council would look at what could be done to level it. As the
drainage of the floodwater relied on gravity, if the river
was high it ponded behind the flood bank, so the council
would look at ways the water could be confined to affect less
The council would meet residents again in October with some
options for consideration, including things the council could
do and what the individual landowner could do to improve the
situation short and long term.
It would also be a chance for residents to put forward their
ideas for fixing the problems.
The township paid a targeted rate for flood protection but
fell outside the West Taieri drainage scheme.
