Neighbours of a Queensberry farm are concerned about earthworks ''obliterating'' a stream and negatively impacting on the ecosystem.
The Central Otago District Council received two submissions opposing an application for retrospective land-use consent on a farm on the north side of Poison Creek.
The application was made on behalf of owner Lynn Wills at the council's suggestion after it was notified of earthworks on the property.
A report by council planning consultant David Whitney said Mr Wills breached district plan rules by digging a 1km and 3m wide ''bench'' into a slope near the border of his property to enable the building of a stock-proof fence and provide space for a water-system pipe.
The application said the council had ''not made any real effort to inform or educate the rural community and the rural contracting and fencing industries of the existence'' of the rule.
