We are currently working on a large boundary survey (2000+ acres) that consists of a number of small tracts (approx 45 tracts) acquired over the years. There are upwards of 500 individual corners throughout the property. The plat will be several pages at 1"=200'.
At that scale, it will be difficult to describe each individual corner on the face of the plat. There are some corners that have 3 existing monuments (tree at corner with an iron pin online on each side of the tree) so it would get pretty ugly pretty quick.
We are trying to decide how we are going to communicate the necessary information in a decent looking yet effective manner.
In the past, on large boundaries for the USFS or USACE, we have employed the use of corner tables. We would give each tract a name, such as 1234, then number each corner on that tract, such as 1234-1, 1234-2...
Then we would create a table that displays the corner monument name, coordinates, description and an inverse to the next monument. The table also contains a column for station and offset for those monuments that are along the highway right-of-way.
I am interested in hearing how some of you have dealt with this. I look forward to suggestions. Thanks.
Are these properties contiguous?
If they are, what does your client think?
And, what has he told you are the future plans?
(Send my $5.00 for advice ok?)

Many Map Pages
A key map with all tracts marked and indexed. All exterior lines to be numbered (EX001, etc.), with a well noted POB and an exterior line table if it fits. Index of following maps with parcels per each map.
Subsequent maps to an appropriate scale for the information included. Keep scales to a minimum, 50', 100', 200', 400'or500', 800'or1000' but no odd scales unless absolutely neccessary. I doubt a single 200' scale can cover the variety. Each map to include a small key map with that particular map area shaded. I would put extra effort into seeing that each tract fits fully on a single map at the cost fo a few more pages.
Make sure every description includes "Tract AQ on Key Map of Big Survey, Map File Book 123/Page 17, more particularly described on Map 3, Map File Book 123/Page 19"
Your exterior description should reference the whole set, and each course should reference "along Adjacent Lot 321 and Interior Tract AQ (Map 3)"etc.
The nearest example would be a large major subdivision/condominium plat.

Good Nate.

Yes, that is how to do it.
Also have a small key map in one of the corners of each sheet.

What Paul said, plus an enlarged detail, which may, or may not be to scale, to clarify those instances where needed, such as your tree with 2 line pipes example.

Take Advantage Of A Roll Plotter
Plot it at 1"=400' or 500' scale on a 36" x whatever sheet that it all fits on. It is easier to think out the overall plan with the whole thing readable to an extant in front of you. If you have access to a 42" or 48" roll plotter even better.
Back in the day I was regularly engineering major subdivisions, I often plotted on large and long sheets. I can recall some road profiles on 24" x 12'+ sheets that I would work on scroll fashion. A 250 lot major sub could easily be 4-5 plan sheets and 10 or more plan and profile sheets. Figuring out how to dice up and orient a large plan into 12" wide strips for 1"=50' Plan and Profile sheets was best done by redlining a complete 50' scale plan.
BTW, do you have a paper/vellum/mylar single work sheet for this project?
