Help with survey stake markings please

[sti491]

Hi. I am hoping someone here can help me out. The town has dug up our street a dozen times or so doing new water, sewer and storm drains. Now they are re-surfacing our road & parking access outside our beach condo. The road is going to be concrete. Even with my best Google skills I can not quite make out all these markings. I think I understand "EOC" means edge of concrete, and "FG" probably means finished grade. Can anyone with these skills advise what all the markings mean for me please? There is a "X" marked on the edge of our concrete parking pad, right where dirt is dug up where they will be putting the road. Thanks in advance!

3 foot offset to edge of curb, fill 0.18 foot to finish grade from the x.

interpreted to: at 3 foot from the stake, will be the edge of curb (or concrete); the finish grade will be .18 foot (about 2 1/4") above the x.

It depends on the surveyor whether the 3 foot offrset is from the stake or from the x on the concrete. When I was doing that kind of work, I would have put a 2" x 2" hub at the base of the stake, and the offset would have been from a tack in that hub. The fill would have been from the top of the hub. They may have used the x on the concrete instead. If I was going to use the x, I would have also wrote the offset and fill next to the X.

Thanks so much. That makes sense given the placement. Appreciate it!

Many times instead of "o/s" for offset, it will be a circle with a cross or plus through it.

ssdave .....thanks for the terminology. "Hub" and "tack". Always wondered. Had the 2 sides of my property surveyed YEARS ago and the did the hubs and tacks. Now I only know where 2 are located. My fault....should have taken better care. Thanks.

I would interpret that stake as END of curb rather than edge (or it could be edge of concrete, I guess). Usually the offset is from the face of the curb, but in this case, judging from the picture, it may be the end. I have no idea what that "x" means, and I've done construction layout for almost 30 years. If that's the grade marking, it's sloppy and misleading.

The "X" is where you dig for the buried treasure. Everybody knows that...

The "X" is more than likely where a tacked hub would be at that point if it was in dirt and not concrete. I'd guess most of the 3' offsets each direction of this one are in dirt, with a hub. He could have changed the offset to miss the concrete in that one location I suppose and driven a hub at 2.5' or whatever worked, but the contractor will set his string line at 3' off the back of curb to pave, so that's where he needs the survey info.
