Hi all,

I am in the processing of building a house in the fairfield council area (nsw 2166).

I have decided on a home builder and they initially said I could go thru CDC based on my lot and my 10.7 certificate. After I paid for my contour survey, it was then determined that I could not go thru CDC

They said it was because my contour survey came back and my AHD level was 13.1.

My lot is partly medium and partly low as a result of overland flooding and my 10.7 certificate showed some flood levels, the 1 to 100 year flood max was 13.5 ahd

So i was told that because contour AHD showed (13.1) which was below the 13.5, they said I can't go thru CDC and I must go through DA.

Does anyone know if this is true?

I did contact a random Architect to query this and provided the same info above and they think I can go through CDC even though my contour adh level was below the maximum flood level on my 10.7 certificate.

So I am abit lost. Do you know if my situation above would allow me to go thru CDC?

Is it worth going to another builder? The issue is that I have already spent so much time with this particular builder, I don't know if I went elsewhere if the result would be any different?

I don't have time to do owner builder, so I can't go down the route of architect and building myself etc

Any help is appreciated, reason I prefer CDC is because it's alot quicker, but mainly because it offers a better floor space ratio than DA

Thanks

On your 10.7 cert, are you in a flood zone?

Yes 10.7 is low to medium flood zone for overland flooding.

Not in a flood zone for mainstream flooding.

Hi Simeon, can you please PM me the contact details of the guy you talked about?
I'm in a similar situation to rookie1 - was ready to proceed with CDC until a land survey was done. The builder is saying we have to go through DA now since our land is in a flood affected zone.

Hi EP1

I'll PM you. Not an expert but my duplex build is in a flood zone as well. I am in North Ryde and I applied to Ryde council for their required FFL's and they gave me a report with a RL above the PMF and I am able to use CDC. I know this is not available to everyone in a flood zone.

I hope you can get the answer you need
