Re: PACIFIC HIGHWAY SH10. OF BYRON-TANDYS LANE UPGRADE
36.1km TO 42.1 km NORTH OF BALLINA
SUBJECT: OPERATIONAL NOISE AT OUR PROPERTY

We are in receipt of your letter Ref. No. CA1518.176/S585 that was signed dated 12/9/02 and which included the Noise Assessment Summary Data from 9/03/2002 to 16/03/2002.

We wish to advise that the Noise Assessment Data sheet has readings for eight (8) consecutive days, this is quite impossible, as the meter on our roof was installed and then removed as the operator informed me that there was too much distortion noise in the meter, possibly from rain and he stated that the readings had to be discarded.

The meter was later re-installed by the same operator for three days and picked up about 7.00 PM one evening, therefore, it seems now very strange that we have a Tuesday to Tuesday sequential unbroken date reading in the Noise Assessment Data sheet, a sequence that can only be possible if the sheet was filed in without the use of the noise meter readings.

I supplied the operator with the ladder to install the meter so I was fully aware of his comings and goings during the noise testing.

We therefore suggest that you send your representative over to initiate a new set of reading which I will now keep an eye on the noise collection procedure. You will find that the noise is nothing like that noted on the Noise Assessment Data sheet you have supplied me with.

I am somewhat deaf in one ear and have some hearing loss in the other, and still many nights it is impossible to get to sleep even with the windows closed, which was not the case when the old asphalt Pacific Highway was in use, prior to your construction of the noisy ribbed concrete highway.

You may also while we are at it have the road ditch at the bottom of the driveway checked for invert elevations, we have informed your construction site staff that the ditch is sloping backwards into the property and that causes flooding at the bottom culvert and over your new asphalt surface even with moderate rain runoff. The ditch should be sloped towards the center isle culvert and that culvert should be lowered if it is not low enough to allow the passage of water to the ditch to the south.

You will not need a level to check inverts as it plain obvious to a blind man that the ditch flows backwards, inspect the site during a good storm and you will be convinced

Hopefully you have not released this part of the public works.

We await a representative to come and talk to us and inform us of the procedures that you are going to follow

Yours faithfully
