Pothole and gravel needs topping up

There is a pothole which is increasing in size at the top of the gravel road of houses 13-16 Newport Way. It is becoming increasingly difficult to avoid when driving down the road. The road itself is in dire need of more gravel. This case was reported almost 2 years ago, workers attended with a small amount of gravel and then didn't do anything because they didn't have sufficient t gravel supplies. At the time the workers said the whole road needed more gravel and agreed the grass has now spread over the road due to the lack of gravel. We know have a sloppy mud pit at the top of our driveway as the gravel has completely disappeared and the grass from the park has spread down the road. Rainwater flows from the higher point of the road directly to our property. The road needs in excess of 10T of gravel placing down. We have paid for small amounts of gravel previously to protect our driveway but do need feel this is fair. Our property may flood if the issue of the gravel is not sorted.
