I'm assuming that distance measurements as used on plot plans and property deeds are measured horizontally, irrespective of the grade of the land, unless otherwise stated.
I'm not trying to DIY survey my lot, but the question came up when a neighbor showed me how he'd "located" the back of his 100 foot deep lot by running a tape along the ground, said ground having about a 1.5 in 10 slope most of the way.
I told him I thought the measurement should have been made on the horizontal, and by doing it the way he did, he ended up about a foot short of the line he was seeking.
Correct?
Thanks, guys
Jeff
