+/-2 ft is plenty, I just need a good enough idea of where the property is to drive onto it. My plan is to use pre cut lengths of string/twine/rope, hopefully something that will go 297 ft without stretching too much. I've already made a half-assed attempt at surveying it, this is what i did;
I gave a real estate buddy of mine the tax info, and he was able to find some info as to where the property is. The block they are on is split into 20 lots, with a divide in the middle, so 10 lots on the north side and 10 on the south side. Each lot is 121x297 ft. My lots are 13 and 14, and have 2 lots to the west and 6 lots to the east. I then went to google earth, and found the block. Earth showed a road to the west of the block, and being only two lots to the east, it was the shortest distance. My plan was to measure 242 ft from the road, and locate the survey stake near the measurement, which would be measured via smartphone gps. I cut two fence posts into four small temporary survey stakes.
I then went to the property, only to find two markers, a sign that reads "15", and an old 4x4 fence post about five feet in from the road. I walked east 242 ft-ish from the fence post, and could not locate a marker of any kind, so I placed one of my stakes. I then walked 242 ft-ish further east and placed a second stake. This second stake ended up about 15 ft short of the "15" sign. So, i assumed that this sign was the south west corner of lot 15, which would fit pretty well with my very inaccurate phone measurement. Ive been told that lot markers are usually in the middle, or on the south east edge of lots. If thats true, then im way off.
The only accurate starting point would be the 15 sign, or the power lines to the east, and possibly the post. So if I measure 484 ft from the post, using a buddy and a 242 ft length of small rope, and that is near the 15 sign, then its probably the south west corner of lot 15. I will then measure 726 ft using the above method from the power lines plus a few feet for the easement, and that should be close to the 15 sign. Once I verify that the sign is the south west edge, I'll measure 297ft north from the sign with the compass and a buddy, and place a stake at that point. Then, 242 ft bearing 270 degrees, place stake, then 297 ft 180 degrees, so and so forth. The compass is set at 12 degrees declination, which is correct for here I believe. I mapped the property with earth, based on the gps co-ords for the lots(exact middle of the lots), and took a screenshot.
