Cement "U" drain block with lip. A cast iron grate fits in the insert and is strong and flush with the surface of the drive. Labor intensive to install, but can carry gallons per minute away. Really a good solution if the driveway is concrete or asphalt and downhill. Flood /snow melt relief if you have a place to direct the collected runoff. Easy to clean with broom on surface and, if needed, can be power washed to dump mud, crumpled leaves, etc. maybe once a year.
