It is estimated that the construction costs for Barefoot, Vanderbilt, Clam Pass, Park Shore and Naples Beaches
will be between $16,000,000 - $30,000,000 depending on the project approach, scope and funds available. It
is also estimated that the permit design, plans and specifications for this project will cost $400,000 to
$600,000. Pre- construction, during construction and post - construction activities are estimated to cost an
additional $800,000 and $1,000,000. A preliminary /partial funding request of $600,000 was approved in
Fiscal Year 11 /12 to begin the permit design and detailed project definition. Additional funding requests will
be forthcoming as phased project definition is completed.
The estimated construction cost to renourish the South Marco Island Beach and repair the five existing
erosion control structures is expected to be $3,000,000. A preliminary/partial funding request of $300,000
was approved in Fiscal Year 11/12 to begin the permit, design and project definition.
No additional carrying costs, operating or maintenance costs are expected with approval of the
Engineering Services contract. No additional carrying costs, operating or maintenance costs are currently
anticipated as a result of the Beach Renourishment project itself. As the design and permitting process
advances, the maintenance and lifecycle costs will continue to be evaluated.
Using today's dollars, the total cost to replace the asset is $16,000,000 to $30,000,000. The project has
an expected life expectancy of 10 years generating a hypothetical annual depreciation cost of $2 to $3
million.
.ADVISORY COMMITTEE RECOMMENDATION: At the January 12, 2012 CAC meeting the CAC

SOUTH MARCO ISLAND BEACH NOURISHMENT PROJECT
FIVE -YEAR POST CONSTRUCTION MONITORING REPORT SUMMARY
FEBRUARY 2012
DEP PERMIT 0235209- 001-JC
USACOE PERMIT SAJ- 2005- 2726(IP -MN)
The above referenced document is provided for;
• compliance with the post construction physical monitoring requirements of the permit,
• performance of the project and its effects on the coastal system,
• recommendations for beach management planning.
The project included the placement of approximately 176,000 cubic yards of material on the
beaches of South Marco Island, and the grading of approximately 8,000 feet of existing beach
north of the fill placement. The material was dredged from Caxambas Pass inlet between
November 1, 2006 and January 16, 2007, and the grading of existing beach was completed on
January 10 -16, 2007 while dredging was in progress.
The beach fill spanned approximately 4,400 feet of shoreline beginning at DEP reference
monument R -144 south to monument G -2, located approximately 600 feet south of R -148. The
beach fill design template had a berm crest elevation of 5.5 feet NGVD, a variable berm width
with the narrowest part being the taper at the north end and the widest part north of the Cape
Marco Seawall, a 1:100 waterward slope from 5.5 to 4.5 feet NGVD with a maximum width of
100 feet, and a 1:10 foreshore slope starting at an elevation of 4.5 feet NGVD. The borrow area
had a maximum dredge depth of -15 feet NGVD with a 2 foot overdepth allowance.
Aerial Photouraohs
Rectified aerial images dated August 22, 2011 were submitted with this report. Images normally
acquired by the Collier County Property Appraisers Office at the beginning of the year are to be
submitted to the Department upon availability.
Project Performance
This report presents the analysis of a monitoring survey conducted by Sea Diversified Inc. (SDI)
between December 5t' & 7`", 2011. In general the project is performing well, overall retaining
93% of the post construction volume but erosion continues north of the protection provided by
the segmented breakwater.
Monitoring section limits for this report were based on the monument range information shown
in Tables 1 & 2 below. The shoreline change was measured at the mean high water elevation
of +0.44 feet NAVD ( +1.75 feet NGVD) while the volumetric change was determined using an
offshore closure depth of -11.8 feet NAVD ( -10.5 feet NGVD).'

There has been significant accretion on the beaches north of the project area from DEP
reference monument R -139 south to R -143, and has remained stable in this monitoring period
gaining an average of five feet of beach width and over 11,000 cubic yards of sand in 2011.
The project area lost an average of almost 35 feet in beach width since the post construction
survey, and had an associated volumetric loss of 14,000 cubic yards for the same five -year
period. The majority of the erosion occurred in the southern portion of the project area from
monuments R -147 to G -1 showing an average decrease in beach width of almost 80 feet and a
loss of over 50,000 cubic yards of sand since construction. It should be noted that this change
includes post construction readjustment and lateral spreading. Some lateral spreading moved
north, and at least in part as a result of this, the northern portion of the project area from R -144
to R -146 increased in width by an average of 10 feet and gained almost 40,000 cubic yards of
sand since construction. The accretion to the north may be a compilation of sand migrating
south from shoals at the north end of the island as well as lateral redistribution of fill from the
project area.
The monitoring area at the southern end of Marco Island, bounded on the north by a terminal
groin and containing a revetment, from monument G -4 to G -5, has gained an average of 3 feet
in beach width, and approximately 4,500 cubic yards of material since the post construction
survey. While showing an average decrease in beach width for 2011 of 7 feet, the area gained
over 3,000 cubic yards of sand in this monitoring period. It should be noted that this is in the
south part of the portion of shoreline which responds to the affects of the segmented
breakwater.
Kice Island has eroded since the post construction survey showing losses of approximately
67,000 cubic yards since 2007, and over 14,000 cubic yards during this most recent monitoring
period. The conditions of the shoals, which have been shown to be valuable shorebird habitat,
within the Caxambas Pass area were quantified based on the emergent area estimated from the
rectified aerial images. There was a decrease in emergent area of over 3 acres, from 7.8 acres
in 2007 to 4.5 acres in 2011. Over the entire five -year monitoring period the area has
experienced both of accretion & erosion in part due to the effects of the Tropical Storm Faye in
2008, and the migration of the shoals in the five years since project construction.
Recommendations for Protect Management and Strategic Beach Management Planning
Project monitoring and reporting should continue in accordance with the approved monitoring
plan and specific conditions of the permit.

INTRODUCTION
5/22/2012 Item 11.8.
This report presents the analysis of a monitoring surrey, conducted in December of 2011. This
is the fifth monitoring survey to be conducted subsequent to the January 2007 beach
renourishment project. The survey was conducted by Sea Diversified Inc. (SDI) between
December 5th & 7t", 2011 based on the requirements of the State of Florida Department of
Environmental Protection (DEP) permit number 0235209- 001 -JC dated December 22, 2005,
U.S. Army Corps of Engineers permit number SAJ- 2005 -2726 (IP -MN) issued January 6, 2006,
and the approved Monitoring Plan revised by Taylor Engineering, Inc. dated December 2, 2004
included in Appendix A. A permit modification 0235209 - 002 -EM was issued to Collier County
on December 27, 2006 to include grading of existing beach north of the project area from DEP
reference monuments R -139 to R -144.
South Marco Island and Caxambas Pass are located in Collier County on the southwest coast
of Florida as shown in Figure 1. The monitoring area includes DEP reference monuments R-
144 south to G -5 on the northern side of Caxambas Pass, and K -1 & K -2 south of the pass on
Kice Island.
The project included the placement of approximately 176,000 cubic yards of material on the
beaches of South Marco Island, and the grading of approximately 8,000 feet of existing beach
north of the fill placement. The material was dredged from Caxambas Pass inlet between
November 1, 2006 and January 16, 2007, and the grading of existing beach was completed
between January 10 -16, 2007 while dredging was in progress.

DESIGN PLAN
Figure 2 is an aerial exhibit showing the project extents and monitoring area from DEP
reference monument R -139 south to monument K -2 on Kice Island. The figure shows the
extent of the fill, limits of the beach grading conducted under the permit modification, and the
borrow area. The scope of the monitoring survey data collection and horizontal control for the
survey are also shown in Figure 2.
The beach fill spans approximately 4,400 feet of shoreline beginning at DEP reference
monument R -144 south to monument G -2 (The G -2 profile azimuth is outside of the fill template)
located approximately 600 feet south of R -148. The beach fill design template had a berm crest
elevation of 5.5 feet NGVD, a variable berm width with the narrowest part being the taper at the
north end and the widest part north of the Cape Marco seawall, a 1:100 waterward slope from
5.5 to 4.5 feet NGVD with a maximum width of 100 feet, and a 1:10 foreshore slope starting at
an elevation of 4.5 feet NGVD. The borrow area had a maximum dredge depth of -15 NGVD
with a 2 foot overdepth allowance.
MONITORING SURVEY DATA
The analysis in this monitoring report is based on data from the surveys listed below. Note the
four -year monitoring survey is comprised of three different surveys conducted on different dates
including Caxambas Pass and the borrow area. The borrow area survey is to be conducted at
two -year intervals as described in the monitoring plan attached as Appendix A, and therefore
was not included in the scope for this monitoring event.
• Pre dredging beach survey conducted on October 27, 2006 by SDI
• Post dredging beach survey conducted on January 29, 2007 by SDI
• Four -year monitoring survey conducted in January 2011
• Monuments R -140 through R -148 by M &E on 12/1712010
• Monuments G -1 through G -5 by CEC on 1/19/2011
• Monument R -139, K -1 & K -2 by M &E on 6/2912011
• Caxambas Pass & Borrow Area by M &E on 12/17/2010
• Five -year monitoring survey conducted in December 2011 by SDI
The beach profile cross sections for these surveys are shown in Appendix B. The survey data
for this monitoring period is in DEP & xyz format on the DVD submitted with this report and the
surveyor's certification is attached as Appendix C.
VOLUME & SHORELINE CHANGE
Monitoring section limits for this report were based on the monument range information provided
in Table 1 below. The shoreline change was measured at the mean high water elevation of
+0.44 feet NAVD ( +1.75 feet NGVD) while the volumetric change was determined using an
offshore closure depth of -11.8 feet NAVD ( -10.5 feet NGVD).' The limits of the volumetric
analysis shown as the "Distance from Mon." (Distance from Monument) in Tables 2 & 3 were
determined by the intersection of the 2011 beach profile and the -11.8 feet NAVD depth of
closure.
' -11.8 feet NAVD depth of closure used to maintain consistency with previous monitoring reports.

There has been significant accretion on the beaches north of the project area from DEP
reference monument R -139 south to R -143. The average shoreline change for the area in the
five years post construction is over 90 feet as shown in Table 2, and has an associated
volumetric increase of over 180,000 cubic yards for the same time period. Figure 3 presents the
shoreline change in graphical form to better illustrate the changes in dry beach width since the
post construction condition shown in green. The majority of accretion in the monitoring area
based on the shoreline change is from R -139 to R -145 increasing from south to north. This
accretion is evident in Figure 4a (Page 8) showing the mean high water line (0.44' NAVD) for
the October 2006 pre construction, January 2007 immediate post construction, and December
2011 five -year post construction surveys overlaid on a rectified aerial image of the post
construction condition on January 2007 and August 22, 2011. The beach north of the project
area has remained stable in this monitoring period gaining an average of five feet of beach
width and over 11,000 cubic yards of sand in 2011.

Table 3 (shown below) is an excerpt from Table 2 showing the shoreline & volume change for
the project area with localized changes highlighted for the period since the post construction
survey (cyan), and for this monitoring period (purple). This color coding is to illustrate that from
post construction to present, which included readjustment, the largest losses were at the south
end, whereas, for the most recent monitoring period the losses occurred further north.
Table 3. Shoreline and Volume Change for the Project Area
The project area lost an average of almost 35 feet in beach width since the post construction
survey, and had an associated volumetric loss of 14,000 cubic yards for the same five -year
period. The majority of the erosion occurred in the southern portion of the project area from
monuments R -147 to G -1 showing an average decrease in beach width of almost 80 feet and a
loss of over 50,000 cubic yards of sand since construction. It should be noted that this change
includes post construction readjustment and lateral spreading. Some lateral spreading moved

north, and at least in part as a result of this, the northern portion of the project area from R -144
to R -146 increased in width by an average of 10 feet and gained almost 40,000 cubic yards of
sand since construction.
In this most recent monitoring period erosion occurred from DEP Monument R -145 to R -147
with the majority of the erosion at the southern monuments R -146 & R -147. This section of the
project area shows an average decrease in beach width of 6 feet, and the loss of over 15.000
cubic yards of sand in 2011.
The shaded area in Figure 3 represents the shoreline change within the project area, and a
comparison of changes at different monitoring intervals. Figure 4b (Page 9) shows the change
in the mean high water line since the preconstruction survey. The entire project area from R-
144 south to monument G -1 showed an increase in average beach width, gaining 2 feet in this
monitoring period, while at the same time there was a loss of approximately 11,000 cubic yards
due to changes in profile shape and sand losses seaward of the mean high water line.
South of the Project Area (G -2 through G -5)
This portion of the monitoring area, bounded on the north by a groin and containing an exposed
revetment, from monument G -4 to G -5, has gained an average of 3 feet in beach width, and
approximately 4,500 cubic yards of material since the post construction survey. While showing
an average decrease in beach width for 2011 of 7 feet, the area gained over 3,000 cubic yards
of sand in this monitoring period. It should be noted that this is in the south part of the portion of
shoreline which responds to the affects of the segmented breakwater.
Kice Island (K -1 & K -2)
Kice Island is located south of Caxambas Pass as shown Figure 2. No shoreline change was
noted at Station K -1 in 2006 and 2007 due to the lack of emergent land; however the area lost
over 50 feet of beach at Station K -1 in 2011. Station K -2 shows a decrease in beach width
since 2007 of over 25 feet, but an increase of 5 feet in 2011. The area has eroded since the
post construction surrey showing losses of approximately 67,000 cubic yards since 2007, and
over 14,000 cubic yards during this most recent monitoring period. Most of this volumetric loss
occurs in the nearshore shoal area. Figure 4c (Page 10) shows the changes in the mean high
water line, as estimated from the rectified aerial images, from the immediate post construction
condition to August 2011, as well as the changes in the nearshore shoal region.
Figure 4c (Page 10) also shows the condition of the shoals, which have been shown to be
valuable shorebird habitat, within the Caxambas Pass area. The emergent area of shoal was
estimated from the rectified aerial images. There was a decrease in emergent area of over 3
acres, from 7.8 acres in 2007 to 4.5 acres in 2011.

CONCLUSIONS & RECOMMENDATIONS
The portion of the monitoring survey located on Marco Island showed significant increases in
both shoreline and volume change since the project was constructed five years ago. The
majority of the accretion occurred in the northern portion of the monitoring area including the
northernmost stations within the beach fill limits. Losses occurred in the southern portion of the
beach fill area mainly at monuments R -145 through R -147 north of the area protected by the
segmented breakwater. Although the beach south of the project area in lee of the structures
shows a loss in beach width in 2011, there was an associated volumetric gain for the same
period. This illustrates that the structures add some stability to the beach, yet allow the beach
to respond to natural littoral processes,
Kice Island and the shoals in the highly dynamic Caxambas Pass area have undergone
significant change since the project was constructed as evidenced in the aerial photographs
shown in Figure 4c, and the shoreline change noted at monuments K -1 and K -2. Over the
entire monitoring period the area has experienced both of accretion and erosion in part due to
the effects of the Tropical Storm Faye in 2008, and the migration of the shoals in the five years
since project construction.
The project area has lost approximately 14,000 cubic yards of sand since construction, and over
11,000 cubic yards in 2011, however the beaches both north and south of project area show
accretion since construction. The majority of the accretion is distributed in the northern half of
the monitoring area as shown in Figure 5. This figure shows the post construction volume in
comparison to the volume remaining in December 2011 for the entire monitoring area with the
project area shaded in gray. The accretion to the north may be a compilation of sand migrating
south from shoals at the north end of the island as well as lateral redistribution of fill from the
project area.

Erosion continues north of the protection provided by the segmented breakwater. A feasibility
study by the County2 indicated potential benefit to further analysis to determine the
effectiveness of repairing and /or upgrading the segmented breakwater to provide additional
protection and /or continue periodic renourishment. The project is performing well, overall
retaining 93% of the post construction volume within the project limits.

PHYSICAL MONITORING PLAN FOR THE SOUTH MARCO ISLAND BEACH
RENOURISHMENT PROJECT
Pursuant to 62B- 41.005(16), F.A.C., physical monitoring of the project is required
through acquisition of project-specific data to include, at a minimum, topographic and
bathymetric surveys of the beach, offshore, and borrow site areas, aerial photography, and
engineering analysis. The monitoring data is necessary in order for both the project sponsor and
the Department to regularly observe and assess, with quantitative measurements, the performance
of the project, any adverse effects that have occurred, and the need for any adjustments,
modifications, or mitigative response to the project. The scientific monitoring process also
provides the project sponsor and the Department information necessary to plan, design, and
optimize subsequent follow -up projects, potentially reducing the need for and costs of
unnecessary work, as well as potentially reducing any environmental impacts that may have
occurred or be expected. The physical monitoring plan that follows satisfies this requirement for
the South Marco Island Beach Renourishment Project. If future revision of this plan becomes
necessary, Taylor Engineering will, by written request, notify the Florida Department of
Environmental Protection (FDEP).
The South Marco Island Beach Renourishment Project area extends from R -144 to G-2 at
the northern terminal groin, approximately 600 ft south of R148. The physical monitoring
control area extends 5,217 ft north of the project area b monument R-139 and extends 505 ft
south to the southern terminal groin adjacent to Caxambas .Pass. The northern control area
incorporates monuments R 139 to R -143, and the southern control area incorporates monuments
G -3 to G-5. An additional control area includes profiles Kl and K2 on Kice Island downdrift of
Caxambas Pass to observe potential effects of the borrow site on the downdrift shoreline.
Topographic and Bathymetric Surveys
Beach and Offshore Area
The primary monitoring area, which includes the project (R -144 to R-148, G-I to G-2)
and the control areas (R -139 to R-143 and G3 to G5), will consist of profile surveys every
monument for a total of 15 profiles. The secondary monitoring area includes 2 additional profiles,
K -I and K -2 on Kice Island.
Packet Page -276-
5/22/2012 Item 11.x.
Topographic and bathymetric profile surveys of the beach and offshore shall be
conducted within 90 days prior to commencement of construction, and within 60 days following
completion of construction of the project. Thereafter, monitoring surveys shall be conducted
annually for a period of three (3) years, then biennially until the next beach nourishment event or
the expiration of the project design life, whichever occurs first. The monitoring surveys shall be
conducted during a spring or summer month and repeated as close as practicable during that same
month of the year. If the time period between the immediate post- construction survey and the first
annual monitoring survey is less than six months, then the permittee may request a postponement
of the first monitoring survey until the following spring/summer, A prior design survey of the
beach and offshore may be submitted for the pre - construction survey if consistent with the other
requirements of this condition.
All work activities and deliverables fall be conducted in accordance with the latest
update of the Bureau of Beaches and Coastal Systems (BBCS), Monitoring Standards for Beach
Erosion Control Projects, Section 01000 -Beach Profile Topographic Surveying and Section
01100 - Offshore Profile Topographic Surveying.
Borrow Area
A hydrographic survey of the Caxambas Pass borrow area will be performed. The survey
shall be bounded in the east -west direction by the inlet throat and the offshore 15 -ft water depth
contour and bounded in the north -south direction by the Marco Island south end seawall and
transect K1 on Kice Island. The northern half of the survey domain will be surveyed north -south
at 200 -ft line intervals, the southern half of the domain will be surveyed north -south at 400-ft line
intervals, and the entire domain will have east -west lines at 600 -ft intervals. We defined a high
resolution for the northern half of the survey domain so that the survey may be used to prepare
project plans if Caxambas Pass needs dredging in the near future.
Bathymetric surveys of the borrow area shall be conducted within 90 days prior to
commencement of construction, and within 60 days following completion of construction of the
project concurrently with the beach and offshore surveys required above. Thereafter, monitoring
surveys shall be conducted at two (2) year intervals concurrently with the beach and offshore
surveys required above. A prior design survey of the borrow area may be submitted for the pre-

construction survey if consistent with the other requirements of this condition. Work activities
and deliverables shall be consistent with the BBCS Monitoring Standards for Beach Erosion
Control Projects, Section 01200 - Borrow Site, Shoal and Other Bathymetric
Aerial Photography
Aerial photography of the beach shall be taken concurrently with the post - construction
survey and each annual and biennial monitoring survey required above, as close to the date of the
beach profile surveys as possible. The limits of the photography shall include the surveyed
monitoring area as described above. All work activities and deliverables shall be conducted in
accordance with the latest update of the BBCS Monitoring Standards for Beach Erosion Control
Projects, Section 02000 Aerial Photography.
Report
The permittee shall submit an engineering report and the monitoring data to the BBCS
within 90 days following completion of the post- construction survey and each annual or biennial
monitoring survey. The report shall summarize and discuss the data, the performance of the beach
fill project, and identify erosion and accretion patterns within the monitored area. In addition, the
report shall include a comparative review of project performance to performance expectations and
identification of adverse impacts attributable to the project. Appendices shall include plots of
survey profiles and graphical representations of volumetric and shoreline position changes for the
monitoring area. Results shall be analyzed for patterns, trends, or changes between annual
surveys and cumulatively since project construction.
Monitoring reports and data shall be submitted to the Bureau of Beaches and Coastal
Systems in Tallahassee. Failure to submit reports and data in a timely manner constitutes grounds
for revocation of the permit. Any monitoring information submittal to the Bureau shall include a
transmittal cover letter clearly labeled with the following at the top of each page: "This
monitoring information is submitted in accordance with Item No. [XX] of the approved
Monitoring Plan for Permit No. 0235209 -001 -3C for the monitoring period [.XX].

BIOLOGICAL MONITORING PLAN FOR THE SOUTH MARCO ISLAND BEACH
RENOURISHMENT PROJECT
The Florida Department of Environmental Protection (FDEP) requires the submittal of a
detailed monitoring plan for any proposed beach nourishment project. The biological monitoring
plan that follows satisfies this requirement for the South Marco Island Beach Renourishment
Project. The plan addresses beach compaction, scarp formation, turbidity levels, and marine
turtles.
Sediment Compaction Monitoring
During the three years following fill placement, the permittee will measure sand
compaction in the area of restoration in accordance with the protocol described below.
Compaction testing, performed before the marine turtle- nesting season, determines whether the
beach requires tilling. If the beach is tilled before May 1, no measurement of sediment
compaction is required. An annual summary of compaction surveys and the actions taken shall
be submitted to the FDEP.
Compaction sampling stations shall be located along shore perpendicular transects spaced
500 ft apart along the project area. Three sampling stations — positioned at the dune toe, mid -
berm, and MHW shoreline — shall be located along each transect.
At each station, the cone penetrometer shall be pushed to a depth of 6, 12, and 18 inches
three times (three replicates). Material may be removed from the hole if necessary to ensure
accurate readings, of successive levels of sediment. The penetrometer may need to be reset
between pushes, especially if sediment layering exists. Layers of highly compact material may
lay over less compact layers. Replicates shall be located as close to each other as possible,
without interacting with the previous hole and/or disturbed sediments. The three replicate
compaction values for each depth shall be averaged to produce final values for each depth at each
station. Reports shall include all 27 values for each transect line, and the final 9 averaged
compaction values.
If the average value for any depth exceeds 500 psi for any two or more adjacent stations,
then that area shall be tilled before May 1. if values exceeding 500 psi are distributed throughout
the project area but in no case do those values exist at two adjacent stations at the same depth,
Packet Page -279-
5/22/2012 Item 11.B.
then consultation with the FDEP shall be required to determine whether tilling is required. If a
few values exceeding 500 psi are distributed randomly within the project area, tilling shall not be
required.
Scarp Monitoring
Visual surveys for escarpments along the beach fill area shall be made immediately after
completion of the beach nourishment project and before May 1 for the following three years if
placed sand remains on the beach. In addition, weekly surveys of the project area shall be
conducted during the two nesting seasons following completion of fill placement as follows:
The number of escarpments and their location relative to FDEP reference monuments
shall be recorded during each weekly survey and reported relative to the length of the beach
surveyed (e.g., 50% scarps). Notations on the height of these escarpments shall be included (0 to
18" and greater than 18 ") as well the maximum height of all escarpments.
Escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a
distance of 100 ft shall be leveled to the natural beach contour by May 1. Any escarpment
removal shall be reported relative to R- monuments.
If weekly surveys during the marine turtle nesting season document subsequent
reformation of escarpments that exceed 18 inches in height for a distance of 100 ft, the FDEP
shall be contacted immediately to determine the appropriate action to be taken.
Turbidity Monitoring
Turbidity monitoring, performed during construction in the vicinity of the borrow site
and beach disposal area, will occur at background and compliance locations. The following
discusses methods to monitor the borrow site and beach disposal area as required by the permit.
Borrow Site
Frequency: Every six hours during dredging.
Packet Page -280-
5/22/2012 Item 11.5.
Location: Background: One meter below the surface and one meter above the bottom, at
least 300 meters up current from the dredge site, clearly outside of any turbidity
generated by the project.
Compliance: One meter below the surface and one meter above the bottom, no
more than 150 meters down current from the dredge site, within the most dense
portion of any visible turbidity plume.
Beach Disposal Area:
Frequency: Every six hours during pumping operations.
Location: Background: Mid- depth, at a point approximately 150 meters offshore and 1,000
meters up current from the discharge point, clearly outside of any turbidity
generated by the project or coming from the inlet.
Compliance: Mid - depth, at a point approximately 150 meters off shore and no
more than 150 meters down current from the discharge point, within the densest
portion of any visible turbidity plume. These locations may change if a mixing
zone variance is granted.
Turbidity monitoring data, submitted to the Bureau of Beaches and Wetland Resources
and to the Northwest District Office within one week of collection, will consist of the following
information: (1) permit number; (2) "South Marco Island Beach Renourishment Project "; (3)
dates and times of sampling and analysis; (4) a statement describing the methods used in
collection, handling, storage and analysis of the samples; (5) a map indicating the sampling
locations, current direction, plume configuration and the location of the dredge and discharge
point(s); and (6) a statement by the individual responsible for implementation of the sampling
program concerning the authenticity, precision, limits of detection and accuracy of the data.
Monitoring reports shall also include the following information for each sample that is taken: (a)
time of day samples taken; (b) depth of water body; (c) depth of sample; (d) antecedent weather
conditions; (e) tidal stage and direction of flow; (f) wind direction and velocity; and (g) DGPS
position.

Marine Turtle Nest Monitoring
The proposed South Marco Island Beach Renourishment Project may require
construction during the sea turtle nesting season. A marine turtle monitoring plan is outlined
below.
Onshore Monitorine
A daily marine turtle nest survey of the nesting beach in the vicinity of the project
(including areas of beach access) shall be conducted starting May I and continue until October
31. Nests potentially affected by construction activities shall be relocated. Nests requiring
relocation shall be moved no later than 9 a.m. the morning following deposition to a nearby self -
release beach site in a secure setting where artificial lighting will not interfere with hatchling
orientation. Nest relocations, in association with construction activities, shall cease when
construction activities no longer threaten nests. Nests deposited within areas where construction
activities have ceased or will not occur for 65 days shall be marked and left in place unless other
factors threaten the success of the nest. Such nests will be marked and the actual location of the
clutch determined. A circle with a radius of ten (10) ft, centered at the clutch, shall be marked by
stake and survey tape or string. No construction activities shall enter this circle. No adjacent
construction will begin which might directly or indirectly disturb the area within the staked circle.
All nesting survey and nest relocation activities shall be conducted only by persons with
prior experience and training in these activities and who are duly authorized to conduct such
activities through a valid permit issued by the Florida Fish and Wildlife Conservation
Commission (FWC), pursuant to Florida Administrative Code 68E -1.
In the event a sea turtle nest is excavated during construction activities, all work shalt
cease in that area immediately and the permitted person responsible for egg relocation for the
project should be notified so the eggs can be moved to a suitable relocation site.
Marine turtle nest monitoring shall continue after construction is complete. Reports on
all nesting activity shall be provided for the initial nesting season and for a minimum of two
additional nesting seasons. Monitoring of nesting activity in the three seasons following
Packet Page -282-
5/22/2012 Item .E.
construction shall include daily surveys and any additional measures authorized by the FDEP.
Reports submitted shall include daily report sheets noting all activity, nesting success rates,
hatching success of all relocated nests, hatching success of a representative sampling of nests left
in place (if any), dates of construction, and names of all personnel involved in nest surveys and
relocation activities. Monitoring shall occur in the project area and equal length of adjacent non-
filled beach. Data will be reported separately for filled areas and non - filled areas in accordance
with Table 1.
Surveyors, upon locating a dead, injured, or sick endangered or threatened sea turtle
specimen, must notify the FDEP. Care should be taken in handling sick or injured specimens to
ensure effective treatment and care and in handling dead specimens to preserve biological
materials in the best possible state for later analysis of cause of death. In conjunction with the
care of sick or injured endangered or threatened species or preservation of biological materials
from a dead animal, the finder has the responsibility to ensure that evidence intrinsic to the
specimen is not disturbed.
Following marine turtle nesting season, a report summarizing turtle nesting within the
beach construction area shall provide data to assess emergences, nests, and reproductive
success /failure in the beach construction area. Nesting data, submitted to the FDEP, will include
separate reports, one for filled beaches and one for non - filled beaches, and shall include numbers
of nests lost to erosion or wash out. Table I provides the appropriate format and required data for
reporting nest data to FDEP.

Beach Monitoring Profiles R -138 through R -148, G1 through G5 and K -1 and K -2
(Kice Island), Marco Island, Collier County, Florida.
This survey report was prepared to accompany the digital data files (ASCII X,Y,Z) submitted to Humiston and
Moore Engineers that were acquired as part of the South Marco Island, Beach Monitoring Survey. In addition
to the XYZ data files SDI has included digital photographs of each profile (N, S, E, and W), scanned field
notes, meta -data file and profile and survey control spreadsheet ( *.xls). The survey encompassed upland
topographic and offshore bathymetric profile data collection of (17) historic beach monitoring lines R -138
through R-148, G1 through G5 and K -1 and K -2. This survey report is not valid without the signature and the
original raised seal of a Florida Licensed Surveyor and Mapper.
2. All field data collection activities meet or exceed the Minimum Technical Standards set forth by the Florida
Board of Professional Surveyors and Mappers in Chapter 5J -17, Florida Administrative Code, pursuant to
Section 472.027, Florida Statutes.
3. The information depicted herein represents the results of the survey on the dates indicated and can only be
considered as indicating the general conditions existing at the time.
4. Horizontal data are in feet relative to the Florida State Plane Coordinate System based on the Transverse
Mercator Projection for Florida, East Zone (0901), North American Datum (NAD) of 1983, 1990 Adjustment.
Vertical data are in feet relative to the North American Vertical Datum of 1988 (NAVD 88).
5. Bathymetric data was collected using a Trimble Real -time Differential Global Positioning System (DGPS) for
positioning and an Odom model "Hydrotrac" sounder, using a 200kHz narrow beam (3 °) transducer. In order
to minimize motion induced by wave action a TSS model "DMS -05 ", 3 -axis motion sensor was used.
Differential corrections were acquired from the U.S. Coast Guard Navigation Beacon System. Horizontal
position accuracy was verified using published profile control points. The sounder was calibrated prior to the
start of the survey following manufacturer recommended procedures.
6. Tide reductions were made from observations at a tide staff set to 0.0 feet relative to NAVD 88. The tide staff
was attached to a pipe driven to refusal and located near and relative to profile control monument R-146
having a published elevation of 13.31 feet, NAVD 88.
7. Topographic data was
