Rainwater and drainage
If the plot has little fall, request a measured drainage design before assuming a permeable surface alone will resolve ponding.
Why it matters for your driveway repair: Show the direction of falls, where water gathers and every visible channel, gully or discharge point. For a driveway repair, it helps distinguish a local defect from movement, drainage or base problems that need a wider scope.
