Rainwater and drainage
If the driveway falls towards the pavement, include an assessment of how runoff will be contained or drained appropriately.
Why it matters for your tarmac surfacing: Show the direction of falls, where water gathers and every visible channel, gully or discharge point. For tarmac surfacing, it can affect excavation, compaction, course depths, drainage, edge support and the handover programme.
