Rain has postponed work and at one stage the seed mix spread over the surface was washed away after a torrential downpour.

Now it seems that the oval's new level playing surface is causing troubles of its own with water running down into neighbouring properties.

During recent rains Gowan Place resident Kristy Conyard said that her backyard had become flooded and is still damp in one corner.

"We've been here for five years and have never seen anything like this before," she said.

"The water was literally running down the footpath and straight into my yard and water flowing through the backyard out onto the street.

"There's still a muddy area in the corner of the backyard."

Not only is the yard sodden, but the house is showing sides of water damage and movement.

"I know that houses move over time, but there are cracks in there that have just appeared and you can see the water that's now just laying around the foundations," Mrs Conyard said.

At Napier Oval itself there are signs of Blayney council's attempts to mitigate the damage caused by the water.

In front of the toilet block a new drainage channel has been installed and water barriers are in place.

Along the edge of the new ground there is evidence of water channels eroding the playing surface.

There are 2.5 kilometres of irrigation piping laid, 560 metres of cabling and 82 individual sprinklers in place at Napier Oval.

The $531,000 project is essentially a completely new ground and was funded through the state government's Stronger Country Communities Program and the NSW ICC T20 World Cup Cricket Legacy Fund.

A council spokesperson said that after the massive rain event in March which caused the initial damage to the oval, they were notified of stormwater running down Gowan Place.

"Staff shaped the ground and installed barriers to direct the water flow away and the grass cover has since increased," the spokesperson said.

"To date, there have been no other official complaints from residents. Any other residents experiencing issues with the water flow are encouraged to contact Council directly via phone or email."
