Reporting Unclear Lot Dimension on URAR Form Using GIS Map Tool

Stay late, or wait until project schedule pressure is over, plop it into survey software, determine acreage.

It is fun!

Wait till you get a convex meeting a concave, you will really be wrapped into an S!
 
are we getting a little too anal for 1 line on the front page?
 
On my software you put the dimensions in by front, left, rear, right. In my area most property cards list the site by acreage (such as 0.27) and give a front dimension, an effective width and a depth. The effective width times the depth is generally close to the listed acreage. Many plats do not list all sides and many are not square or trapezoidal. Finding an old survey with atual measurments is often not possible (without a long search of the court house records). My software ill alloy listind the squre footage or acrage without having to put in dimensions. Irregular lots may have many segments (straight & curved) and will not fit the space allocated. If there are not too many sides I may list all sides separated by a comma (UAD may not like this). For odd shaped lots I include an aerial of the lot to give its visual viability for use as a lot. If UAD checker allows it use see addena in the dimensions field, then have a comment in the addenda. Since the form compares area the square footage or acres is more important. State your source and I included a comment in the addenda that the lot size my be slightly different depending on source used. Do not assume the assessor has the correct acreage listed. I have found they sometime have not corrected acreage when vacated roads or partialn lots are added to the property. GIS measuring tools are approximate, but can be used to see if the lot size you use is appropriate.
Thank you for the detailed response! Much appreciated ☺️

So far I have only encountered one of the four sides of the lot having a curve. The plat will give the length of the straight part of the curve but then give a code for the curved part. If you look at the code it will list radius, arc, length etc. I have been taking this length and using it as part of the dimensions.
So for example: (made up numbers) 125 X 154 X 138 X 25 (curve) X 98
I enter this and then the total software has given me an area but it will be different than what is listed in the MLS. Not sure what the correct way to handle this is‍♀️

See attached GIS subdivision Plat from Assessor for site dimensions. No survey was supplied to the appraiser and the appraiser is not a licensed land surveyor or GIS mapping professional. All information is taken from Assessor's information. Please see attached "metes and bounds legal description" from deed included in the exhibit. Not your job, in my opinion.
 
I took a CE class from OREP last year, and the instructor (Tim Anderson) said not to use estimates of the dimensions—only certifiable information, e.g. legal descriptions, deeds, etc.
 
So what would you put if one dimension is a curve and the length of the curve is supplied?
Also what would you put if you didn’t have exact measurements?

Would you put the lot square footage listed in the MLS? Or at least somehow list the dimesions you know for sure?
 
From HUD:

There is no UAD requirement for the site dimensions field, only the site area field. HUD's protocol provides best practice IMO.

For site area, don't just go off the MLS. Find the original source. It is probably going to come from a GIS calculation at the County or from a service like Realist.
