More flood misery for Christchurch

Flood-ravaged Christchurch is under deluge again today, with 50mm falling in the past 24 hours, heavier than was forecast.

The Heathcote River has breached its banks in places, causing some road closes, Christchurch City Council says.

The Flockton Basin area, flooded three times in less than two months, is again under water in many places.

Flood-waters on roads and parks may be contaminated, the council has warned.

Residents are being advised to avoid the water where possible or to wash their hands and remove and wash any clothing that gets wet.

Drivers have been asked to slow down when driving through flooded areas as vehicle wake can send waves into homes and businesses.

Extra care needs to be taken when driving on Cressy Terrace/Park Terrace, Lyttelton due to slips.

Geotechnical consultants are monitoring known risk areas.

"The council is asking people in hillside areas to be vigilant, and keep an eye out for any telltale signs of land instability, including new cracking to land, buildings, driveways or paths; existing cracks that get longer, wider or deeper; leaning or bulging of retaining walls; or rockfalls.

If anyone notices changes, or has concerns, they are being urged to call the council's call centre on 941 8999, or 0800 800 169.
