ORDINANCE NO. !) 9111
A resolution by the Augusta-Richmond County Planning Commission recommending that the
Subdivision Regulations be amended as follows:
AN ORDINANCE TO AMEND THE SUBDIVISION REGULATIONS OF AUGUSTA,
GEORGIA, ADOPTED BY THE AUGUSTA COMMISSION ON MARCH 18, 1997
BY PROVIDING FOR CERTAIN PLATS AND SURVEYS TO BE REFERENCED
TO THE STATE PLANE COORDINA TIS.
THE AUGUSTA COMMISSION HEREBY ORDAINS:
SECTION I. That the Ordinance regulating the subdivision of land in Augusta, Georgia, is
amended by adding the following new section:
SECTION 303: SURVEY AND PLA T STANDARDS
A. The intent of this section is to require cenain land parcels, located within reasonable
distance from monumented Augusta and or geodetic control points, to be referenced by
field survey to Augusta and or geodetic control points which are defined by state plane
coordinates. In cases where monumented Augusta and or geodetic control points are not
within a reasonable distance as defined in this document, the requirement will be to
reference the survey to points which are identifiable on the Augusta orthophotomaps.
Propeny surveys affected by this article will be referenced to their accurate geographical
locations, and therefore can be plotted in their correct position on the state-plane-
coordinate-based Augusta mapping system.
B The following surveys require ties to geodetic control monuments:
I. Any subdivision of five (5) or more lots total aggregate. including all phases and '
sections severed from parent parcels at the time of this ordinance, within a one
mile traverse distance along public roads of Augusta and or geodetic control
monuments.
2. Any boundary survey for which the sum of the length of the lines platted is
greater than the traverse distance along public roads to Augusta and or geodetic
control.
3. Any subdivision of twenty-five (25) or more lots total aggregate, including all
phases and sections severed from the parent parcel at the time of this ordinance.
regardless of distance to Augusta and or geodetic control.

b. If control is extended more than 12 mile from the control monument to
the property boundary, second order class 11 (1/20,000) specifications shall
be followed.
c. Plats to be recorded must bear certification of the class of specifications
followed.
2. Global Positioning System (GPS) Surveys:
a. If GPS is used, procedures shall be followed to ensure survey grade
compatibility with the nearest coUnty and or geodetic control monuments. Survey
grade GPS receivers shall be used with a manufacturer's stated accuracy of at
least :I: 5 cm :I: 2 ppm. It is realized that the nearest station may not always be
suitable for occupation by GPS because of obstructions, lack of property owner
permission, or other reasons. The intent here is to make ties to network stations
within 3 to 5 miles from the project and to avoid establishing new coordinates on
property comers that will not tie on the ground by conventional surveys to an
accuracy of 1/10,000 to existing monuments that already exist in the project area.
b. Plats to be recorded must bear certification stating the GPS receivers used are
of survey grade and have a manufacturer's stated accuracy of at least:l: 5 cm
:I: 2 ppm.
3. Plat Requirements:
a. State plane coordinates shall be shown on the plat for one property comer.
The coordinates and names or descriptions or of county and or geodetic
monuments used for control will be noted on the plat with the grid distance and
azimuth shown to at least one of the coordinated property comers.
b. Horizontal ground distances (not grid distances) will be shown on the plat for
all segments of the boundary survey. A combined state plane coordinate - sea
level reduction factor will be noted on the plat. Area will be based on horizontal
ground distances.
c. All bearings will be referenced to state plane coordinate grid north.
F. Electronic Data Files. If the plat is generated with computer-aided drafting procedures,
Augusta may request a copy of the electronic file to be provided on Augusta supplied
medium. In addition, the tinal plat submission shall include the type and numbers of
copies for approval and recordation.
G. County and or Geodetic Control Monuments.
I. The Augusta Information Technology Department will keep on file the location of
all County and or Geodetic Control Monumehts and will provide to the Registered
\

'.
4. Any non-agricultural industriaVcommercial development of 25 or more acres
regardless of distance from Augusta and! or geodetic control.
C. Surveys Exempt From Requirements For Ties To AuguSta And Or Geodetic Control
Monuments. It is considered very desirable for surveyors to tie all surveys,
whenever possible, to the state plane coordinate system. Nothing in these exemptions
is intended to discourage surveyors from tying surveys to the state plane coordinate
system.
The following surveys are exempted from the requirement for ties to county and or
geodetic control monuments:
t. Surveys of 5.00 acres or less, such as mortgage surveys, in existing
subdivisions initially recorded with the Augusta Clerk of Commission.
2. Any survey not specified in "Surveys Requiring Tie To Augusta And Or
Geodetic Control Monuments" as outlined above.
D. Surveys Requiring Orthophoto Locator Tie. All surveys not included in "Surveys
Requiring Tie To Augusta And Or Geodetic Control Monuments" and not exempted
in "Surveys Exempt From Requirement For Ties to Augusta And Or Geodetic Control
Monuments" shall have a "locator tie". A locator tie is defmed as a bearing and distance
tie from a property comer to a point identifiable on the orthophoto map such as a building
comer. a road intersection with a driveway, or other point that can be accurately spotted
on the orthophoto.
To support this requirement, Augusta will make copies of the orthophoto maps in
digital format available to licensed surveyors and will provide access to these maps
in the Tax Assessors Office.
E. Survey Requirements. Survey requirements specified in this article are only for control
survey connections between Augusta and or geodetic survey monuments and land
parcels. Boundary surveys shall be performed in accordance with the State Minimum
Standards published by the Georgia State Board of Registration for Professional
Engineers and Land Surveyors unless more stringent requirements are specified herein.
In so far as possible. control surveys between Augusta and or geodetic monuments and
property boundaries shall be extended from the nearest Augusta or geodetic control
monuments. Augusta specifications for horizontal control are as follows:
I. Terrestrial Surveys:
a If control is extended no more than Y2 mile from the control monument to
the property boundary, third-order class 1 (1110.000) specifications shall be
followed.

2. Augusta Control Monuments shall be any monumented property comer or control
monument that has been tied to published Geodetic Control Monuments and is on
file with the Augusta Information Technology Department.
H. Violations of this Section. Complaints against violators of this article shall be reviewed
by a panel of Georgia Registered Land Surveyors that shall be selected by the
Augusta-Richmond County Planning Commission, before the complaint is filed with the
Georgia State Board of Registration for Professional Engineers and Land Surveyors by
the Augusta-Richmond, County Planning Commission, Register of Mesne Conveyance, or
other department.
SECTION II. All Ordinances or parts of Ordinances in conflict with this Ordinance are hereby
repealed.
