Robster 1973

Has anyone had any experience with a Section 50 licence? In particular if New Roads and Street Works Act 1991, Highways act 1980 is been correctly applied by Staffordshire county council here. I have made application to excavate the high way to connect a property I am building to Severn Trent foul and surface water drains. However I am informed by Highways and the built country that I need to apply and pay for two licences. I am of the opinion that this is excessive because there is not twice the work for highways to do to issue the licences. -One trench will be dug to connect to both drains which are adjacent at the same time. -The drawing and maps submitted for each licence would be identical. -Severn Trent will make one inspection of the work prior to adoption. -The contractor I have appointed also says one licence is required.
