Drawing Scale & North Arrow
The Idaho Board of Professional Engineers and Professional Land Surveyors have indicated that Title 55, Chapter 19 is applicable to subdivision plats, i.e. that a plat is a form of a Record of Survey, and as such the information required to be supplied on a Record of Survey, should also be contained on a subdivision plat.
Review
· Is there a graphic scale on the drawing? Does it scale correctly? Is it labeled correctly?
· Does the line work on the drawing scale correctly? For plats that are not original or a vacuum frame mylar, there could be some distortion in one axis of the drawing. This may create problems for verifying dimensions
· Are there any details on the drawing that are scaled differently than the main drawing? If so, are the scale values shown, and does the detail scale correctly?
· Is there a North Arrow on the drawing, and is it oriented correctly?
· Are there any details on the drawing that are oriented differently than the main drawing, and if so, do they have their own North arrow shown?
· Are there more than one ?
