I'm finishing up a boundary line adjustment drawing between two parcels that I staked last year. The county requires all fences to be shown on a site plan before the plat is submitted, but I didn't locate any new fences after the survey that broke up the land. I was told they were going to fence it but I didn't want to try to get to the north lines right now since it's just a big mud-snow mess out there and will be for the next few weeks so I imported lines from autocad into TBC and plotted the property lines on Google and this is what it looks like:
The Google photo was taken a few months after the survey was done and clearly shows the new fence lines that I didn't locate. They are right on my lines. For what I need it for it's good enough. Now let's hope they didn't mess up the corners-since it isn't part of the legal for the adjustment, I'm not worrying about it.
Not sure what your tolerances are but using satellite imagery even at 0.30m resolution at that scale, a mm on the screen is maybe 20-30 meters on the ground?
If it's a drawing on a sketch, isn't your line width going to be around a millimeter anyway? I mean, I wouldn't put any dimensions on it based on the imagery, but just the fact that he is showing that a fence exists seems adequate to me. It tells the client where there are fenced or unfenced lines. Just thinking...
This is just the preliminary site plan for the county. One of the requirements is to show the fences along the boundary, since I've already completed the survey and located all the existing fences I don't see any reason to locate fences in an area that isn't even going to be in the new legal. I'm not showing any dimensions on the fences-just graphic. For the site plan there are no bearings or distances-just the property lines without dimensions, fences, utilities, roads, buildings and easements. The fence lines on the north end were the only item I don't already have. So I'm just confirming their existance with Google and will show them along the property line.
But isn't the reason why the county required that you plot out the position of the fences was so that the surveyor would check the positions on the ground as compared to computed positions?
If you did not have anything to do with the positions of the fences then why indicate them at all? Or just indicate only the portions that you surveyed.
Given that 1 mm on the image = 20m on the ground, the fact still remains that you are not sure if the corners of the fences followed what you staked on the ground.
It is akin to me sitting in my office & creating topographic maps using the free SRTM elevation data & claiming it was from ground survey shots.
I only plot what I surveyed on the ground.
What do you have there? a prairie dog town or drill holes?
Humm, well looking at the boundary plotted on Google it is within 1' of the fence corners. That is plenty close for my 1"=500' plot. I staked the line to be fenced but I didn't know if it got constructed or if it was placed where I staked; this confirms it.
The site plan is nothing offical-it only is plotted on a sheet of paper and it isn't sealed or kept by the county. They want to know what is affected by the boundary line adjustment and that is 1/2 south of the new fence.
I'm not going to spend client's money for something this trival-sometimes photos are just fine and this is one of those cases.
20m? as you can see the red property line is less than 1' from the brace panels.
prairie dog heaven. They really need to do some rodent control.
And for more effect, you can also show the cows and cow paths.
