Sec. 4.04 Metes and Bounds Surveys
A metes and bounds survey will be required on parcels of land to be purchased for use as
District or Residency offices or Maintenance Area Headquarters and may be requested by other
State Agencies. When the acquisition of land involves property owned by U.S. Government, State
Agencies, National Forest Services, Railroad Companies, and Power Companies (Dominion VA
Power), a metes and bounds survey is required. See Section 4.02.1 and the Right of Way Manual
of Instructions Sections 5.6.6-5.6.9. These surveys will be prepared by computer-aided drafting
techniques (CADD). Each sheet must contain a title block, filled out completely. The title block will
contain the following information: county name, magisterial district, the name of the Survey Party
Manager or Consultant, date of survey, scale bar, the proposed use of the parcel of land and the
name of the person or persons from whom it is to be acquired.
The survey must be tied into the construction centerline or baseline of adjoining or nearby
projects and the existing right of way, whether owned in fee or as an easement or dedication, shall
be shown. Directions and distances to nearby towns as well as the adjacent route and project should
be shown. Measure the angles and compute the bearings to the nearest second and measure
distances between transit points to the nearest one-hundredth foot (0.01-ft). The survey plat shall
show all pertinent features such as streams, wooded areas, swamps, roads, buildings, fences, etc.
The owner names and property lines of all adjoining properties must be shown.
The bearing and length of each course should be shown on the inside of the ‘lot’ line and
recorded bearings and length, if any, should be shown in parenthesis on the outside of the ‘lot’ line
(Figure 4-E). When a part of the boundary line is a curve, the central angle (or delta), length of
chord, chord bearing, length of curve and radius of the curve must be shown in the CADD file.
Areas greater than or equal to 1 acre will be shown in acres to 3 decimal places (x.xxx). Areas less
than 1 acre will be shown in square feet to the nearest square foot.
A closed-loop traverse shall be completed in the field around the perimeter of the boundary.
All angles and distances shall be entered, in sequence, into a Coordinate Geometry program. The
"Compass rule" method of adjustment may be used and a least squares adjustment is also
acceptable. The output data from the computer will be in two sections. The first section will contain
the data just as it was entered from the field book, or data collector, and will give the bearing of the
error, the length of the error and the ratio of the error. The second section will show the closed,
adjusted data with the area of the traverse in acres and square feet. The adjusted traverse must have
a zero error of closure in order to receive the correct area from the computer. However, the metes
and bounds shown on the CADD file should be that of the closed data provided the error of closure
does not exceed one in ten thousand (1:10,000) for a rural area survey or one in twenty thousand
(1:20,000) for an urban area survey. Should the closure exceed the permissible amount, sufficient
field checks should be made to correct any discrepancies.
A copy of both sections of the output form must be uploaded to the appropriate ProjectWise
folder and an email sent to the Central Office GeoSpatial Survey Support group at GeoSpatial-
description written will commence at the nearest offset point with the lowest stationing off the
construction centerline thence clockwise around the parcel. If the construction centerline is not
available, an easily identified, unique point will be chosen as a point of beginning and the courses
will run in a clockwise direction.
