Road drainage not fit for purpose, flooding to properties due to diversion or profile

Storm water / drainage flow from Kewstoke Road travels along the road and enters 33 and 31 Kewstoke Road causing flooding. This is partly due to a dropped curb stone and damage to the public pavement caused by what appears to be water meter / water mains work whereby the pavement was cut and replaced by tarmac. The area has depressed also allowing a pathway for all of the road’s water along the gully, down the dip and across 33 and 31. We have lots of videos and more photos, but I was unable to upload anything additional. This has happened to our house for many years, presenting itself as significant penetrating damp to the front left side of our house. We have rotten floor joists / wet rot and have had to dig a trench to lower ground level along the side of our house and along the front of our drive in an attempt to stop water entering our property. Happy to show the investigating officer and explain further. The trench has helped to a point for us (33), but all water still runs off the road and along our property into 31 causing flooding. The current drainage and flow is inadequate, not fit for purpose and is causing damage to our properties. Kindly please investigate, happy to provide further information and evidence as required. Yours faithfully
