However, the plan excludes the heavily flooded Snodgrass Rd area on the north side of the Orowai River and the lagoon.
The Buller District Council and the West Coast Regional Council have jointly announced a business case to be submitted to the government. The total bill is $ 54.4 million, of which $ 42.3 million will be required by the government.
The July 2021 flood damaged 563 homes, or 23% of the town’s housing stock.
A wide range of solutions include 18km walls and embankments, including Carter’s Beach breakwaters to protect against the Buller River.
About half of the walls are on public or reserve land, 44% on private land and 6% on KiwiRail land, crossing 6 farms, up to 12 lifestyle blocks and 7 homes. In addition, for 15 to 20 properties, there is a dike or breakwater on the spare land adjacent to the property.
A viewing platform has also been proposed.
The council excluded the Buller River, which cuts directly into the sea from the mouth of the Orowai River, and the dredging of the breakwater on the Snodgrass Peninsula, which has about 35 homes.
They say the proposed plan was designed to avoid $ 400 million in damage to the Westport building alone.
“It shows the plight we are facing,” said Mayor Blur Jamie Crane.
The council said building a breakwater in Snodgrass would significantly raise the water level of real estate over 6km upstream. To do this, the structure of the Westport Ring Bank on the other side of the Orowite estuary needs to be raised. You also need to increase the flood depth of the land in the upstream (unprotected) Orowite Overflow Area.
It can be difficult to get resource consent because the toes of many parts of the stopbank extend to the estuary.
The council also flagged other issues, including discussing the impact of the embankment on the peak flood flow of state highway bridges with the New Zealand Department of Transportation.
Another proposal involves relocating the airport to higher ground at some stage, and the report also covers relocation and withdrawal from Westport Township.
“We have a town that needs growth. We have land available outside the hazard zone and are willing to work with the central government to move from forced retreat to strategic relocation based on future growth. There is a meeting. “According to the report.
Alma Road, a terrace on the south bank of the Buller River, is large due to its proximity to the existing town, easy service by infrastructure, high location away from coastal disasters, and its proximity. It was the perfect option for a large, controlled setback. To major transportation links.
But Mr. Crane said yesterday he wouldn’t pay to relocate people.
However, people may have the money to build their own Bund or raise the height of their homes.
“It’s a handup, not a handout.”
Business case goes to government this week.
Mr. Klein said he would call on the government to speed up the rules on the dangers of the new Tai O project. We will discuss some of the proposals, such as flood walls, to see if funding is available.
