3.0 REVIEW OF APPROACH TO SAND SURVEY AND BEACH PROFILE PROGRAM OBJECTIVES
In responding to the RFP, the Committee has requested that the Consultant
analyze the course of action proposed to accomplish the stated objectives
(ref. Section 1) of the Sand Survey and Beach Profile Program. We believe
that beach profiling supplemented with field reconnaissance, photography, and
expert analysis is the principal means to accomplish the objectives of the
Committee's program. We applaud the foresight of the City of Carlsbad to es-
tablish a systematic data collection and archiving program, and offer the
following comments and recommendations.
3.1 Data Acquisition
Schedule of Beach Profiling
Tekmarine concurs with the proposed schedule of semi-annual surveys
in the months of April and October. Profiles obtained at this time of
year will be representative of typical winter and summer profiles,
respectively, and will coincide in time with the on-going COE surveys in
the Carlsbad area.
Also in regard to scheduling, it is emphasized that the time
separation between the wading and boat surveys, as well as the overall
time to complete the field survey should be kept to a minimum. In so
doing, a "snapshot" of the beach profile can be obtained by minimizing
the occurrence of naturally occurring profile changes throughout the sur-
vey.
Tekmarine has been performing nearshore surveys for the USACOWLAD
since October, 1986, and is contracted to continue the task until April,
1988. One of the basis for our selection was our ability to perform the
survey in a timely manner. The survey involves beach profiling at 57
stations between the U.S.-Mexican Border and Dana Point. We completed the

first field survey in 11 days, the second in 7 days, and the third in 11
days. In comparison, the previous contractor required one to two months
to survey a comparable number of stations.
Wading Surveys
It is important to stress that the wading survey should be extended
as far offshore as possible. Through our repeated survey experiences, we
have discovered that the wading survey can be extended routinely to a
water depth of about 3 m below mean lower low water (MLLW) loss
of data accuracy. Profiles extending to this depth would allow a
detailed analysis of sand movement not only on the beach but also on the
seabed over a considerable portion of the surf zone where the predominant
sand movement is known to take place.
without
The wading profiles are particularly well suited for tracking the
longshore transport of the beach fill which will be placed south the
Oceanside Harbor from the forthcoming bypassing operations, because they
are inexpensive relative to boat surveys and can be implemented at short
notice. Wading profiles alone were sufficient to perform real-time
tracking of a sand wave migrating along the shoreline, as demonstrated in
our recent 1985-86 study at San Onofre (Grove, Sonu and Dykstra, 1987).
of
Boat Surveys
It is important that the deep-water profiles extend some distance
beyond a 10-meter (30-ft) depth. This requirement stems from the fact
that in the Oceanside littoral cell, in which Carlsbad is located, the
offshore boundary of significant profile change is located at ap-
proximately 10 m (Dolan et al., 1987; Teknarine, 1987). Since the
offshore boundary of the control volume used for sediment budget analysis
should be located beyond this point, a 12 m (40-ft) depth is a suitable
limit both in terms of the practicallity of the survey operations and the
analysis of sediment budget. Figure 3-1 shows examples of profile
closure at depths near 10 meters in the Oceanside littoral cell.
Beach Reconnaissance and Photography
The texture of the beach, featuring sediment types and depositional
forms (such as cusps, berms, aeolian deposits, debris lines, escarpments,
backshore and coastal structures, installations and facilities, bluff
faces, etc.), as well as surf zone dynamics (such as rip channels,
breaking wave patterns, wave incidence angles, wave runup, etc.), can be
highly useful information in understanding and interpreting the surveyed
profile data. For this purpose, expert observation of the state of the
beach and beach photography at each time of profile survey should be
made part of the profile survey program. For this purpose, it makes sense
that the survey program be conducted by trained coastal engineers. The
photographs should not only record the profiles being surveyed, but also
the intervening beach between the spaced profile stations. For the
inter-station photagraphy, the camera should be positioned at designated
high ground locations and aimed in designated directions, so that the
time-separated scenes may be compared.
LEO Data
Another important source of information on beach processes is the
LEO (Littoral Environmental Observation) program data. The program con-
sists of periodical recordings of observed waves, currents (longshore and
rip currents), beach profiles, and sedimentary features by local person-
nel (park rangers, etc.) which were initiated by the Corps of Engineers
in the late 1960's in southern California and Lake Michigan. At
Carlsbad, two stations were activated and the program was continued for
two years in 1969 and 1970. A sample of the output from this program,
specially prepared by the Coastal Engineering Research Center

for Tekmarine, is shown in Figure 3-2. This example clearly bears out
the presence of a longshore current reversal which is known to occur in
the Oceanside littoral cell mainly during the summer months (June-
. September), although the duration of the reversal and its intensity are
known to vary from year to year. All this information is extremely valu-
able for the understanding of local coastal processes, making the LEO
program one of the most cost-effective and practical means of acquiring
such information. Unfortunately, the LEO program has been discontinued
since then, and we strongly recommend that the program be revived for the
City of Carlsbad. The Corps of Engineers Los Angeles District is willing
to help re-start the program (at a one-time fee of less than ap-
proximately $2,000) which will include data analysis at the Coastal
Engineering Research Center, as well.
3.2 Survey Data Analysis
Data Processing
The data analysis has two separate but related aspects: data
processing and interpretation. The data processing is a procedure by
which the raw field data is read, checked, tabulated and plotted into
useful forms. This procedure can be handled by a special data base
management technology currently in use at Tekmarine to process the Corps
of Engineers nearshore survey data. This technology is illustrated in
Figure 3-3.
The programs BPAS (Beach Profile Analysis System) and ISRP
(Interactive Survey Reduction Program) have been developed by the Coastal
Engineering Research Center. Although these programs have the
capabilities for quality-control checking of the raw data, we have added
another tier of quality control with a highly efficient QA program. The
BPAS and ISRP along with the Tekmarine QA program allow an extremely wide
range of data manipulation capabilities embracing practically all

possible varieties of profile data analysis, including, among them, data
plotting, profile comparison, profile volume computation, volume changes,
bar-chart displays of shoreline or volume changes as a function of either
space or time. An example of shoreline change and volume change result-
ing from time-separated profiles along the southern California coast is
shown in Figure 3-4.
Data InterpretatiodSediment Budget
The second aspect of data analysis, i.e. data interpretation, es-
sentially boils down to constructing a sediment budget. Figure 3-5 shows
a schematic illustration of the concept of sediment budget. The sediment,
budget analysis is a technique of quantifying all the inputs and outputs
of sediment relative to a designated segment of the coast, called control
volume, in reference to the various sources, pathways and sinks of sedi-
ment which affect the littoral zone. By balancing these various
elements, one seeks to identify specific processes which may be linked to
the behavior of beach profiles at issue (i.e. either erosion or
accretion) in that segment. A reliable sediment budget allows one to
bring more scientific and quantitative judgements into the evaluation of
the cause, the present status and the future trend of beach erosion.
The procedure of constructing a sediment budget is not automatic,
since there are usually more unknown variables than can be uniquely
determined. The data on beach profiles plays an important role in reduc-
ing the number of such unknowns and thereby enhancing the credibility of
a constructed sediment budget. Additional important information will be,
the knowledge of site-specific shoreline history, historical data
(including air photos), and wave climate, among others. Still, the
ability of an expert to carry out insightful reasoning based on his prior
experience in sediment budget and beach processes will play a significant
role. In a recent study performed for the Corps of Engineers Los Angeles
District, Tekmarine (1987) conducted an extensive review of the current
sediment budget methodology with special reference

to the Oceanside littoral cell. Major findings resulting from this
study, some of them startling in nature, can be used readily for con-
structing a sediment budget for Carlsbad. Tekmarine has also acquired a
detailed site-specific knowledge of both historical and current coastal
processes along the Carlsbad shoreline through several local projects,
including (1) repeated nearshore surveys (April and October 1986; April
1987; for USACOE/LAD), (2) a wave overwash and aeolian sediment transport
study (1986 for USACOE/LAD), (3) sediment budget analyses (1986-87; for
USACOE/LAD), and (4) its on-going project on the engineering of the tidal
entrance at Batiquitos Lagoon and the beach nourishment for the City.
Tekmarine engineers have undertaken at least a dozen ground reconnais-
sance trips between south Oceanside and the entrance to Batiqujtos Lagoon
since April 1986.
Data Base
Coastal engineering is basically an empirical discipline, and its
planning and design can only be as good as the data. We strongly feel
that it is about time that the City of Carlsbad consolidate the! informa-
tion and data on its shoreline. At the least, the City should have a
central information file which catalogues all the historical data, com-
plete with annotations as to their usefulness, and whereahouts. The
Corps of Engineers Los Angeles District has already performed this type
of task for the entire Oceanside littoral cell as part of the Coast of
California Storm and Tidal Wave Study, so that the remaining work for the
City of Carlsbad is to single out the part which relates to the City
shoreline. The catalogued information should consist of historical
bathymetric surveys, profile surveys, aerial photographs, ground
photographs, hydrological’ and hydraulic information, annotated bibliog-
raphy, and the LEO data.
Additionally, a computerized data base may be constructed to con-
solidate the past and future profile data into a form allowing ready and
easy retrieval. As already shown in Figure 3-3, a generic data base
16
.
management program, DBASE, which stores the beach profile survey data in
a versatile data base is already in use for the Corps of Engineers.
Sharing a data base management system with the Corps of Engineers will
facilitate data acquisition from the USACOE/LAD and the Coastal
Engineering Research Center. By virtue of the on-going data management
services for the Corps of Engineers, Tekmarine can provide a similar
service to the City of Carlsbad without additional development work.
3.3 Consulting Services
The need for unscheduled consulting services on shoreline problems
exists for the City of Carlsbad. It is desirable that the consultants
providing such services are located nearby, so that their physical
presence can be realized at short notices. It is also desirable that the
consultants represent the best expertise available locally in terms of
the full spectrum of potentially required services which include under-
standing the science of coastal sediment transport processes, performing
engineering planning and design of major coastal facilities arid erosion
mitigation measures, experience in public presentation and court witness,
and field survey and oceanographic monitoring expertise. Tekriarine has
both the track record and resources to meet these requirements fully.
We feel that Tekmarine can be particularly useful to the City by
virtue of its insightful understanding of the local coastal processes, as
evidenced by our on-going role as the coastal engineering consultants for
the Batiquitos Lagoon Enhancement Project. Additionally, iis shown in
Figure 3-6, it took Tekmarine to derive a new and very important inter-
pretation from the dredging data at Oceanside Harbor. Our interpretation
determined that the maintenance dredging at Oceanside Harbor since 1965
should be viewed as two successive periods of distinct dredging rates
(450,000 cy/year to 1971 and 293,000 cy/year after that), rather than one
whole period with a single average dredging rate (300,650

cy/year). Our further investigation revealed that the significant drop
in dredging rates at Oceanside Harbor since 1972 had to do with the
change of the dredge disposal locations further away from the harbor
beginning in 1972. Surprisingly, the change in the disposal location in-
volved a distance of only less than a mile. For the City of Carlsbad,
this means that more of the material would reach its shoreline (because
less is returning to Oceanside Harbor) if the spoil is placed farther
from the harbor, and that it should encourage the disposal locations to
be moved as close to its boundary as possible. Furthermore, the disposal
operations should be scheduled to avoid the season of 1itto:ral drift
reversal. The consultants to the City should investigate varioiis options
with sufficient supporting scientific evidence to press the points maxi-.
mizing the benefit to the Carlsbad shoreline.
As shown in Figure 3-7, the San Diego Gas and Electric Cob carries
out beach disposal of the dredge spoils originating from the Agua
Hedionda lagoon. Whereas the dredger is most interested in removing the
spoils to a location where they are least likely to return to the lagoon,
the City is most interested in keeping the material on the shoreline
within the city limit for as long as possible. These interests are es-
sentially conflicting to each other, and the city should consider having
the consultant speak on its behalf. This role will be extremely impor-
tant to the City's shoreline, since the dredge volume from Agua Hedionda
ranges from as much as about 250,000 to 500,000 cy every two years.
Other important areas where the consultant could prove highly valu-
able may include, but not be limited to, an assessment as to the
downcoast limit of the adverse effect of Oceanside Harbor, emergency
measures against freak storms, coastal water quality associated with'off-
shore sewage disposal, rip tide predictions.

4.0 BEACH PROFILING TASK
As part of the overall Sand Survey and Beach Profile Program, shallow-
water profiles are to be obtained at eleven (11) stations, while deep-water
profiles are to be obtained at four (4) stations. The surveys are to be con-
ducted on a semi-annual basis and documented by written reports. Tekmarine's
proposed approach to these specific tasks are described in this section.
4.1 Project Team
Mr. Chris Butcher shall serve as the Project Manager (ind be the
principal liaison with the City of Carlsbad. He is presently managing,
the nearshore surveying program being conducted for the COE, ilS well as.
the field surveys associated with the Batiquitos Lagoon Enhancement
Project. Mr. Butcher will supervise and participate in the field sur-
veys, data analysis, and report preparation.
Dr. Sonu, the President of Tekmarine, will be primarily responsible
for expert data analysis and interpretation, but will also make one-day
reconnaissance trips to the Carlsbad shoreline on a bi-monthly tiasis. He
is currently managing the coastal engineering and beach ncurishment
design services associated with the Batiquitos Lagoon Enhancement
Project, and recently completed a review of sediment budget methodology
specific to the Oceanside littoral cell for the COE.
Mr. Butcher and Dr. Sonu have worked together for 10 years.
Combining their resources with those of the Tekmarine staff, we are able
to provide the turnkey service of field data acquisition with expert data
analysis and interpretation.

4.2 Survey Methodology
4.2.1 Location of Survey Stations
Semi-annual beach surveys have been performed in the cities of
Carlsbad and Oceanside on a regular basis since December, 3.981. From
December, 1981 to February, 1983, the surveys were jointly sponsored by
Carlsbad and Oceanside. The Carlsbad-sponsored surveys were concentrated
between Buena Vista and Agua Hedionda Lagoons and consisted primarily of
wading surveys. From November, 1983 to the present, the surveys have
been sponsored by the USACOE/LAD as part of the CCSTWS. The latter sur-
veys are widely-spaced but extend throughout the city limits and include
both wading and boat surveys. Tekmarine has performed the COE-sponsored
surveys since April, 1986, and is under contract to continue the surveys
through April, 1988.
To enhance the data collected in this program, Tekmaririe proposes
to locate the survey stations in consideration of the foregoing: surveys,
and thereby maximize the benefit to the City of Carlsbad. The ap-
proximate location of the proposed survey stations as well as those for
the on-going COE-sponsored surveys are illustrated in Figure 4-1. The
proposed locations are selected to complement the COE-sponsored surveys
and provide a nearly-uniform distribution of wading and boat surveys
throughout the City of Carlsbad. Furthermore, as many of the proposed
stations as possible are located at the site of the previous city-
sponsored surveys, as illustrated in Figure 4-1. By re-occupying the
original survey monuments, a direct comparison may be made hetween the
profiles for the proposed and historical surveys.
Special attention is called to the fact that two of the proposed
wading survey stations are located just north of the City of Carlsbad in
Oceanside. These stations are situated near the southern term:inus of the
Oceanside Harbor bypass disposal area and are critical to tracking the
alongshore migration of sand.

4.2.2 Wading Surveys
As specified in the Request for Proposal, Tekmarine p:coposes to
utilize wading and boat surveys to obtain the shallow- and deep-water
profiles, respectively. A conceptual representation of thesz methods,
which Tekmarine has employed successfully for the COE since April, 1986,
is illustrated in Figure 4-2. The accuracy of these methods shall
satisfy the following criteria, which are the same as those established
by the COE for their surveys:
Survey Method Vertical Accuracy Horizontal Accuracy
+
+ -1.0 ft
-10.0 ft
+
-+ Wading -0.1 ft
Boat -0.5 ft
The wading survey shall be conducted by a two-person crew equipped
with a Geodimeter Model 122 Electronic Distance Meter (Ref. Fig. 4-2).
The Geodimeter is selected because it has a wide beam divergence and be-
cause its fast-tracking mode determines the range and elevation of the
survey rod reflector in less than one second. These attributes greatly
expedite acquisition in the surf zone, where the rod is stationary
for only brief intervals between wave impacts.

6) Distances and elevations were measured at intervals of 30 to 40 ft,
and at major slope breaks, from the monument to the specified
depth. Bottom composition was noted by the rod man, if discern-
i ble.
7) Additional random points along the range line were suirveyed as a
check on the original data as the rod man returned to the monument
for a closing backsight.
In addition to the foregoing, a photographic station shall be es-
tab1ishe.d at each station and at an intermediate point between stations
where alongshore and on-offshore photographs shall be taken during each
survey.
Utilizing the fast-tracking geodimeter, a strong swimmer, and an
extendable surf rod, the wading survey shall be extended to a minimum
depth of 3 m, MLLW. Tekmarine has routinely performed wading survey to
these depths in Carlsbad and other southern California areas since April,
1986 (see Plate 4-1). The benefits accuring from extending the wading
surveys to these depths include the following:
o Providing profile data in the most active sediment transport zone
even at survey stations where boat surveys are not performed.
o Producing significantly greater accuracy in the region of most ac-
tive sediment transport than could be obtained with boat/fathometer
surveying techniques.
o Enabling the boat surveys to be performed without r2gard to the
tidal stage, and enabling a substantial overlap between the wading
and boat surveys.
The overlap between the wading and boat surveys provides a means of
quality control in that the two independent surveys can be checked
against one another in the region of overlap. The overlap between the

4.2.3 Boat Surveys
The boat surveys shall be performed by a two-person boat crew using
an analog fathometer, and a two-person shore party using an EDM to deter-
mine the boat position (ref. Fig. 4-2). The inflatable boat proposed for
the survey, a Zodiac Mark I11 GR (see Plate 4-Z), offers two distinct
advantages relative to a displacement hull: 1) maneuverability and shal-
low draft, which are essential for data acquisition near the breaker
zone, and 2) resistance to roll, which results in reduced contamination
of The ability of the Zodiac to operate
near and even in the breaker zone enables the boat survey to extend
landward to a typical depth of minus 8 to 10 ft, thereby creating sub-
stantial overlap with the wading survey.
the fathometer record by waves.
Depths shall be measured with a Raytheon DE719C Fathorieter Depth
Recorder, which provides a continuous analog record of the sea:Iloor on a
strip chart. By virtue of its precision, portability, ruggedness, and
low power consumption, the DE719C is well-suited to small-boat survey
operations.
The position of the survey boat shall be determinlgd with a
Geodimeter Model 122 EDM operated by the shore party.. As in the case of
the wading survey, the rapid response and wide beam divergence of the.
Geodimeter greatly expedites the boat tracking operation.

The range line monument was located and the alignment was estab-
lished with a hand-bearing compass.
The shore party erected two high-visibility range markers on the
range line to indicate its alignment (ref. Plate 4-2), iind estab-
lished radio contact the the survey boat.
The EDM was postioned on the range line and checked €or proper
operation.
A backsight to the monuent was recorded to establish the horizontal
position of the EDM.
While the shore party performed Tasks 1 through 4, the boat crew
calibrated the'fathometer,
The boat was positioned at the seaward terminus of the range line.
Just prior to commencing the survey run, the shore crew directed
the boat to the exact range alignment by radio.
When the boat was on range, the shore crew notified the boat crew
to commence the survey run. As the boat proceeded landward, the
shore crew recorded the distance to the boat at 10-secorid intervals
while simultaneously directing the boat crew to place an event mark
on the fathogram. The boat speed was typically constant at 4
knots, resulting in a spacing of 70 ft between the successive pairs
of depth-distance measurements.
The survey run continued until breaking waves or shallow water
forced the boat crew to abandon the range line.
A second survey run was conducted immediately after the first
the boat proceeding in an offshore direction.
with

10) At the conclusion of the survey runs, a final calibration check was
performed on the fathometer.
Three procedures shall be routinely adopted to assure quality con-
trol of the boat survey data:
o Fathometer "bar check!' calibrations at each range line.
o Two boat surveys at each range line.
o Extending boat surveys inshore until they overlap the wading sur-
vey.
Because the speed of sound in sea water varies with the vater den-
sity, because water density can change abruptly along the coast due
to such factors as river discharge, upwelling, and coastal density
fronts, the fathometer shall be calibrated at each survey station. The
calibration procedure known as a "bar check", is depicted in Figure 4-4.
An initial calibration is accomplished by suspending a sonically reflec-
tive bar beneath the transducer at a depth of minus 10 ft, and adjusting
the instrument readout to this depth. To account for water column varia-
tions in the speed of sound which may occur in the water column, the bar
is lowered in 10-ft increments to a maximum depth of minus 40 ft and
raised in similar increments to the original depth of minus 10 For
each known bar depth (-10, -20, -30, and -40 ft), the difference between
the actual bar depth and the fathometer readout is noted. These dif-
ferences are subsequently used to develop a speed-of-sound correction
curve which is applied to all fathometer data obtained for that par-
ticular range line.
and
ft.
If the calibration line on the fathometer drifts during the survey,
the bar check procedure shall be repeated with minor changes at the con-
clusion of the survey. Instead of adjusting the fathometer readout to

match the bar depth of minus 10 ft, the difference between the bar depth
and the fathometer readout shall be noted as in the case of the other
depth increments (-20, -30, and -40 ft). The results are then averaged
with the pre-survey data in developing the final speed-of-sound correc-
. tion curve. Experience has indicated, however, that fathometer drift
proves to be insignificant. Of course, should a major instrument drift
occur during a survey, the entire calibration and survey would be
repeated .
The practice of performing two boat surveys shall be adopted at
each range line. In addition to providing confirmation of the survey
accuracy, the double runs aid in distinguishing seafloor features such as
rock outcroppings from wave contamination of the fathograms. By conduct-
ing successive runs in opposite directions along the range line (onshore
and offshore), the encounter frequency of the survey boat with the incom-
ing waves is altered. This shift changes the nature of the wave
contamination in the two fathograms, permitting the bottom features to be
more easily recognized.
As a final quality control measure, the boat survey shall be ex-
tended inshore until it overlaps with the wading survey. During data
processing, this overlapping region shall be compared to verify agreement
between the two independent surveys. It should be noted that this
measure is feasible only if overlap data exists and if the wading and
fathometer surveys are performed within a short time of one another, say
24 hours. If the wading and boat surveys are separated by a substantial
time period, comparison of the overlapping data is invalidated due to the
possibility of naturally occuring profile changes between the surveys.'
As previously discussed, our proposed survey methods ensure a substantial
overlap and eliminate the dependence on the tidal stage, thereby making
it possible for us to perform this quality control measure.

As part of the survey results, Tekmarine proposes to include
profiles from the on-going COE surveys at Range Lines CB-0720, CB-0760,
CB-0800, CB-0830, OS-0900, and OS-0930 (see Figure 4-1). In addition,
profiles from the regions north and south of Carlsbad, historical records
and other data sources shall be perused for information relevant to con-
clusions regarding beach dynamics in the City of Carlsbad, inclusive of
data and resources from previous and/or on-going consultants, as avail-
able to Tekmarine.
Because the October, 1987 survey is a baseline survey, profile com-
parisons in the October, 1987 report shall be limited to those stations
where historical profiles exist. Following the April, 1988 survey, a
complete data set will be available for analysis, from which inore com-
prehensive conclusions, including a sediment budget, shall be dl2rived.
As indicated in the proposed Table of Contents, attachments to the
report shall include beach profile computer data files md beach
photographs inclusive of the COE survey stations listed above. Tekmarine
proposes to submit the data files in the COE BPAS format to make them
compatible with historical COE survey data. The data file shall be
provided on a medium (e. g., floppy disk, 9-track tape) compatible with
the City of Carlsbad computer system. The data may also be prwided in
other formats for the convenience of City employees, if so desired.
4.4 Schedule
Tekmarine believes the survey schedule specified in the R2quest for
Proposal is most appropriate. Conducting the surveys in the nonths of
April and October results in profiles that are representative of the
seasonal winter and summer profiles, respectively. Furthermore, these
dates coincide with the on-going COE surveys, which makes integration of
the COE data into the Carlsbad data mol-e meaningful. To provide a
36
I '-.
"snapshot" of the beaches, Tekmarine proposes to conduct the field sur-
veys in a one- to two-day period.
Because we propose to include the COE data in our survey reports,
availability of our report delivery schedule shall be contingent on the
the COE data. To allow time for processing, review, and approval of the
COE data, we propose to deliver our survey report approximately three
months after each field survey. During the interim, we shall provide
preliminary results in the form of a letter report.

5.0 COSTS
The Committee has requested that the Consultant provide a fixed-price for
the execution of the two semi-annual beach profile surveys inclusive of the
written survey reports. Tekmarine proposes to provide these services, as out-
lined in Section 4, at the following cost:
October, 1987 Survey and Report $11,284
April, 1988 Survey and Report 8,624
Total: $19,908
The differential in cost between the two surveys is primarily at-
tributable to the initial verification and/or establishment of survey station
monuments prior to the October, 1987 survey.
Consulting services in addition to the foregoing shall be charged in ac-
cordance with our standard conditions of engagement, which are summarized in
Appendix B.
