Heres a few views of the next door plot after 'raising....
As can be seen, the plot followed the level line from my levels, not the shallow gradient, which meant that by the time the raising on this adjacent plot got to the top end (nearest to the camera) of the plot, there was in fact, no raising at all.
I think I benefit from this: being level, not sloped, any water will not all run off towards my plot.
(I hope everyone is happy with the resized pictures prior to upload?)
