Board of Professional Land Surveyorp
RULE CHAPTER TITLE: Minimum Technical Standards


PURPOSE AND EFFECT: The Board of Professional Land
Surveyors is required to establish minimum technical
standards for land surveying. The proposed revisions clarify
and refine provisions in the existing rule. and provide
minimum technical standards for additional types of surveys.
SUMMARY: The proposed changes include new definitions,
a reordering of definitions, clarification and refinement of
existing minimum technical standards, and the addition of new
minimum technical standards for geodetic surveys and
ordinary high water mark surveys.
RULEMAKING AUTHORITY: 472.027, F.S.
LAW IMPLEMENTED: 472.027, F.S.
SUMMARY OF THE ESTIMATE OF ECONOMIC
IMPACT OF THE RULE: The proposed amendments to Rule
21HH-6 will add minimum technical standards for Geodetic
and Ordinary High Water Line (OHWL) surveys.
Additionally, these proposed amendments clarify and
otherwise modify existing minimum technical standards for
the preparation of land surveys in the State of Florida. The
estimated economic impacts of these proposed amendments
are summarized below. This statement of estimated impact
is based upon the presumption that the several definitions and
standards incorporated into these amendments, especially
with respect to OHWL surveys, are correct and adequate.
No agency costs are expected to be incurred beyond the costs
associated with development and adoption of these
amendments. The primary basis for this expectation is that
the two additional surveys dealt with in these amendments
already are conducted by Florida land surveyors. These
amendments simply direct and establish standards for
existing activity rather than creating additional activity.
No significant matters of cost have been identified for land
surveyors, individuals retaining land surveyors to conduct
surveys pursuant to these minimum standards, the State of
Florida. or the general public. This conclusion of no significant
cost results from the present existence of the additional
surveys addressed by these amendments.
If the proposed minimum technical standards are adequate,
these amendments should prove beneficial to all affected
parties. Land surveyors will receive the benefit of direction
in their preparation of surveys. The owners of property
desiring land surveys, especially OHWL surveys, will be
benefited by the existence of such standards and the assurance
of minimum quality of land surveys. The State of Florida will
be benefited by state sovereignty lands being properly
identified so that they may be protected from wanton or
inadvertent intrusion. The general public will receive the
benefit of enhanced protection of publicly owned lands.
It is estimated that there will be minimal beneficial effects
upon competition in that the specification of technical
standards may result in additional land surveyors competing
to do Geodetic and OHWL surveys. It is estimated that there
will be no effect on employment.
The body of the Economic Impact Statement provides all of
the data and methods used in making the estimates and
conclusions summarized herein.
S These proposed amendments may be marginally beneficial to
small land surveying businesses in that the tasks they must
Perform are provided minimum technical standards and in that


certain of the existing technical standards are clarified.
Additionally, small businesses needing land surveys may be
marginally benefited from the specification of minimum
technical standards and the increased reliability which such
standards should provide.

the water during normal years, and reflects the point to which
the water has exerted dominance over the bed so as to wrest
the bed from terrestrial vegetation and destroy its value for
agricultural purposes. Generally, the OHWM is a visible mark
in which parties providing for a water boundary between them
would naturally have in their minds. In all cases the OHWM
is a natural object, and is to be sought for as other natural
objects are sought for and found by the distinctive appearances
they present. Generally. this natural boundary is capable, not
only of being ascertained upon inquiring but also, of being seen
and recognized in the common practical affairs of life. It neither
takes in overflowed land beyond the bank, nor includes swamps
or low grounds liable to be overflowed, but reclaimable for
meadows or agriculture, or which being too low for reclamation
though not always covered with water, may be used for cattle
to range upon as natural unenclosed pasture. The OHWM is
an ambulatory boundary and is subject to gradual and
imperceptible change due to erosion, accretion, reliction or
submergence.

not be in error more than the contour interval. A surveyor shall
run test profiles and check horizontal distance when he certifies
the correctness of the information shown on a topography
survey obtained by aerial photography.

and Quantity and eightt of Way Surveys.
(1) Construction Layout Survey: when requested by
either the owner or the eontraeteer the surveyor may provides
construction staking, for use by the contraeter. tThese stakes
must be based on controls established using the survey
standards as defined in Sections .6.003 and 46.004 of this rule.
The stakes provided should be adequate in number, and
horizontal and vertical position; and elevation so that the
physical items can be constructed from the plans as designed.
(2) As-Built or Record Surveys or As Built Surveys:
(a) When the surveyor performs as-built or record
surveys, he Reeerd Surveys or As-Bilt Surveys, when
per~ermed. shall obtain field measurements of vertical or
horizontal dimensions; of constructed improvements, so that
the ensietrued feeility ean be delineated in seeh a way that
the designer may determine the substantial aeeuracy of the
leeation of the eenstruesio'n Any and shall prepare drawings)
released shah which clearly show by symbols, notations, or
' delineations, those constructed improvements facilities located
by the field survey. All drawings prepared shall meet these
minimum technical standards as applicable and will be certified
as such.
(b) The horizontal accuracy shall be such that it may
be determined whether the constructed improvements) facility
encroaches upon adjoining properties or whether it is properly
placed on the property, in rights of way, or in easements
provided fe the facility. The vertical and horizontal accuracy
shall be such that it may be determined by the designer
whether the improvements were feeility was constructed with
substantial accuracy.
(3) Quantity Surveys: when the surveyor may measures
and computes quantities, he shall as requested, by obtaining
horizontal and vertical dimensions adequate to delineate
graphically geometric configurations andor dimensions that
can be mathematically computed.
(4 Right of Way Survey: the survey shall indicate the
relationship of all section lines, quarter section lines, land grant
lines, recorded subdivision lines and recorded subdivision block
lines, that lie within or adjacent to the right of way that are
materially affected by the right of way. The relationship
between the lines and the rights of way shall be supported by
field measurements.
(a) Prior to the completion of a right of way survey for
the purpose of acquisition of property and engineering design,
a control survey consisting of the center line and/or base line
indicating the relationship, supported by field measurements,
of all section lines, quarter lines, land grant lines, recorded
subdivision boundaries, and recorded subdivision block lines
shall be performed.
(!b Final right of way survey drawings prepared after
acquisition shall show directly on the map or in tabular form


the appropriate book and page where the description is
recorded.

21HH-6.0052 Ordinary High Water Mark (OHWM)
Surveys.
(1) Applicability and Intent. This rule establishes
additional technical standards, procedures, criteria and general
methodology to be applied by land surveyors registered in the
state of Florida for the determination of the location of the
ordinary high water mark (OHWM). It is the intent that nothing
in this rule is in conflict with established Federal and Florida
law and existing principles of accepted land surveying
standards. For the purpose of this rule, the terms ordinary high
water mark (OHWM) and ordinary high water line (OHWL)
may be used interchangeably.
(2) Minimum Technical Standards for Ordinary High
Water Mark Surveys. The following additional minimum
technical standards shall aply to all OHWM surveys:
(a) Existent location unless prior date specified. The land
surveyor will determine the location of the existent OHWM,
unless explicitly requested to determine the location of the
OHWM as it existed on a specified prior date.
(b) Surveys tied to corners or other monumentation. All
OHWM surveys shall be tied to a government land office
survey corner or some other well established survey monument
such as a permanent reference monument of a recorded
subdivision plat.
(c) Sinuosities. The survey shall generally approximate
the sinuosities of the OHWM with a meander line of accurately
measured courses and distances connecting together meander
or inflection points which the surveyor determines to be located
upon the OIIWM.
(d) Bearings and distances. The survey drawing shall
provide bearings and distances between adjacent points on the
meander line and for ties from the line to the referenced
monuments. Bearings should be based-on either astronomic
north or grid north of the Florida State Plane Coordinate
ysteim.

(e) Course length. Courses shall be of such lengths as,
in the opinion of the surveyor, are needed to accurately depict
the irregularity of the ordinary high water mark.
(f) Dates. Each meander line of the survey shall be dated
to indicate the date on which the meander points were actually
established in the field. If a meander line is intended to locate
the OHWM as it existed on some prior date, the actual field
survey dates and the depicted prior date, and the means by
which the location was set, shall be noted on the face of the
survey drawing.
(g) Monumentation. All meander or inflection points on
the OHWL survey shall be monumented either directly or by
witness monuments.
(h) Independent judgment. The surveyor shall have
responsibility for and shall exercise his independent judgment
in making the final determination of the location of the OHWM.
The surveyor shall personally examine the bed and the banks
or shore of the water body to locate the positions of the OHWM.
(i) Criteria. The surveyor shall first examine the slope
of the bank and character of its soil for a well-defined line of
demarcation between the bed and the bank. The surveyor shall
then consider the following factors:
1. The banks of a water body often form a marked
escarpment at the limits of its bed. Such escarpments are
formed through the processes of erosion and over-bank deposits
of sediment during high water, forming natural levees. The
OHWL is located below and on the waterward side of the
natural levees.
2. The OHWL is to be found at that point where the
presence and action of the water is so common and usual and
so long continued in all ordinary years that it prevents the
establishment and growth of terrestrial vegetation.
3. The bed of a water body is unsuitable for agricultural
purposes caused by the continued presence and action of the
water flowing or washing over the bed. Larger particle sizes
and decreased organic matter and clays, which result from the
erosive and transportive effects of moving water, distinguish
the sediments found in the bed of the water body from the soils
found on the banks and in the swamp and overflowed lands
that extend landward from the OHWL.
4. The factors enumerated in paragraphs 1., 2., and 3.
are not to be considered as separate tests for determining the
location of the OHWL, but should be considered together as
complementary factors in locating the OHWL.
5. Supplemental evidence, including but not limited to
historical accounts of water levels, use of adjacent lands for
agriculture, statistical analyses of water levels, and prior
surveys of the OHWM. may be used to support the primary
criteria enumerated in paragraphs 1., 2., and 3. for
determination of the OHWL.
(j) Lands not included. The following lands are landward
of the OHWM of a water body:
1. Swamp or overflowed lands, and floodplains adjacent
to a water body that are subject to periodic flooding when the
water body overflows its banks.
2. Beds of non-navigable streams which connect with
the navigable water bodies.
3. Non-navigable sloughs, arms, bays. marshes, flood
channels and similar features that are connected to but are


distinct from the main body or channel of a navigable water
body, as distinguished from the shallow and non-navigable
margins of the main body or channel of the water body.
4. Any man-made flooded area, excavation, canal,
dredged area, or widened channel or border, of or connected
to a non-tidal navigable water body. In such cases, the last
location of the natural ordinary high water mark shall be fixed
using the best evidence available so as to exclude such man-
made change or feature, and shall be so noted on the drawing.
(k) Current Location Presumed to be Natural Location.
The current location of the OHWM shall be presumed to be
its natural location unless there is obvious, competent and
substantial evidence that a change has occurred as the result
of natural or man-made avulsion. If there is such evidence of
avulsion, the location of the OHWL of a non-tidal water body
shall be located at its last natural position before the avulsion.
