1.
As-Built/Record Survey:

show by symbols, notations, or delineations, those constructed
improvements located by the survey.
c.
All maps prepared shall meet applicable minimum technical
standards.
d.
The vertical and horizontal accuracy of the measurements made
shall be such that it may be determined whether the improvements
were constructed consistent with planned locations.
2.

i.
The Council member shall make a determination of the position of
the boundary of real property in complete accord with the real
property description shown on or attached to the survey map or
report.

All boundary surveys shall result in a map.
iii.
Any discrepancies between the survey map and the real property
description must be shown.

evidence of easements or rights-of-way on or across the land
being surveyed shall be located and shown upon the map.
iii.
When streets or street rights-of-way abutting the land surveyed
are physically closed to travel, a note to this effect shall be
shown upon the map.

of building corners as monumentation is clearly noted on survey
drawing.
iv.
When a boundary survey updating a previous boundary survey is
made by the same Council member or firm for the purpose of
locating non-completed new improvements, then property corners
need not be reset; however, when a boundary survey is updating a
previous survey made by the same Council member or firm and is
performed for purpose of locating completed new improvements
then property corners must be recovered or reset. When a
boundary survey updates a previous boundary survey made by a
different Council member or firm for the purpose of locating
either non-completed or completed new improvements, then
property corners must be recovered or reset.
