Location of Driveway ACO Drain?

[mike2016]

The Architect originally specified a drainage channel across the top of the driveway. There is a 0.5 meter drop to the house. The road has a slight dip and the excess water always tends to flow down the estate rather than over the threshold of the new driveway. Now construction at this area could change this behaviour but should I move the drainage channel to in front of the house, or keep it at at the top of the driveway? Or even do both?! Thoughts? Parted ways with the Architect. Thanks.
