Greytown residents to choose flood scheme

GREYTOWN residents are set to decide whether they need new flood defences at the cost of higher rates bills.

New maps showing the extent of a one-in-100 year flood of the Waiohine River have been sent to homes in the area after extensive mapping was done by Greater Wellington Regional Council.

The maps show the majority of Greytown, as well as parts of Carterton, submerged.

Regional council flood protection manager Graeme Campbell is confident the new flood walls will go ahead, despite a $5 million price tag.

“The cost of flooding to the town would be well into the millions anyway, the cost to each household is massive in a flood.”

The entire Wellington region will pay half the cost, with those in the affected areas expected to pick up the rest through a rates rise.

One Greytown resident, Sally Rhodes, thinks the flood defences are a good idea, but has her reservations about the cost. “I think it is necessary, but $5 million is a lot of money.”

The council already has money set aside in the Long Term Regional Plan for a project like this.

Major consultation with local residents is due to begin in the coming months, with the flood protection work planned for completion in 2014.

The existing flood banks have been there, in some part, for nearly 100 years, with various upgrades, most recently in 1999.

These flood defences would protect the town from a one-in-20 year flood only, Mr Campbell says. “There’s plenty of room to improve on that.”

Other, cheaper options have been discussed and include installing better warning systems in the upper reaches of the river and having stronger emergency evacuation plans in place.

Mr Campbell says this option is unlikely to be chosen by residents as they have more to lose from a major flood than an entirely rural area.
