(passing the #200 sieve) or gravel exclusive of shell material (retained by the #4 sieve),
be free of coarse gravel or cobbles, and be suitable for marine turtle nesting.
b. Construction related activities are authorized to occur on the nesting beach (seaward of
existing coastal armoring structures or the dune crest) during the nesting season under the
following conditions.
i. 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 April 15 and
continue until October 31. Only those nests that may be affected by construction
activities shall be relocated unless the Commission has previously authorized
such relocation. 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 such
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 and the
Commission has authorized such relocation. Such nests will be marked and the
actual location of the clutch determined. Stake and survey tape or string shall
mark a circle with a radius of ten (10) feet, centered at the clutch. No
construction activities shall enter thit circle and no adjacent construction shall be
allowed which might directly or indirectly disturb the area within the staked
circle.
ii. No construction activity may commence until completion of the marine turtle
survey each day.
iii.It is the responsibility of the permittee to ensure that the project area and access
sites are surveyed for marine turtle nesting activity. All nesting surveys, nest
relocations screening or caging activities etc. shall be conducted only by persons
with prior experience and training in these activities and who is duly authorized
to conduct such activities through a valid permit issued by the Fish and Wildlife
Conservation Commission (FWC), pursuant to Florida Administrative Code
62R-1.
c. From April 15 through October 31, staging areas for construction equipment shall be

temporary lighting of the construction area is authorized at anytime during the marine
turtle nesting season (April 14 through October 31). No additional permanent exterior
lighting is authorized.
d. From April 15 through October 31, all project lighting shall be limited to the immediate
area of active construction only and shall be the minimal lighting necessary to comply
with U.S. Coast Guard and/or OSHA requirements. Stationary lighting on the beach and
all lighting on the dredge shall be minimized through reduction, shielding, lowering, and
appropriate placement of lights to minimize illumination of the nesting beach and water.
Lighting on offshore equipment shall be minimized through reduction, shielding
lowering, and appropriate placement of lights to avoid excessive illumination of the
water, while meeting all U.S. Coast Guard and OSHA requirements.
e. The applicant shall arrange a meeting between representatives of the contractor, the
Department, the FWC, and the permitted person responsible for egg relocation at least 30
days prior to the commencement of work on this project. At least 10 days advance notice
shall be provided prior to conducting this meeting. This will provide an opportunity for
explanation and/or clarification of the sea turtle protection measures.
f. Immediately after completion of the beach nourishment project, the beach shall be tilled
as described below. Prior to April 15 for 3 subsequent years if placed sand still remains
on the beach, sand compaction shall be monitored in the area of restoration in accordance
with a protocol agreed to by the FWC, the Department, the U.S. Fish & Wildlife Service,
and the applicant. At a minimum, the protocol provided under a and b below shall be
followed. If required, the area shall be tilled to a depth of 36 inches.
g.
All tilling activity must be completed prior to April 15. If the project is completed
during the nesting season, tilling shall not occur in areas where nests have been left in
place or relocated unless authorized by the U.S. Fish and Wildlife Service in an
Incidental Take Statement. A report on the results of compaction monitoring shall be
submitted to the FWC prior to any tilling actions being taken. An annual summary of
compaction surveys and the actions taken shall be submitted to the FWC. This condition
shall be evaluated annually and may be modified if necessary to address sand compaction
problems identified during the previous year.
i. Compaction sampling stations shall be located at 500 -foot intervals along the
project area. One station shall be at the seaward edge of the dune/bulkhead line
(when material is placed in this area) and one station shall be midway between
the dune line and the high water line (normal wrack line).

ii. 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 18 values for each transect
line, and the final 6 averaged compaction values.
iii. If the average value for any depth exceeds 500 psi for any two or more adjacent
stations, then that area shall be tilled prior to April 15. 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, then consultation with the FWC shall
be required to determine if tilling is required. If a few values exceeding 500 psi
are present randomly within the project area, tilling shall not be required.
h. Visual surveys for escarpments along the beach fill area shall be made immediately after
completion of the sand transfer operations and prior to April 15 for the following three
years and all scarps shall be leveled or the beach profile shall be reconfigured to
minimize scarp formation. In addition, weekly surveys of the project area shall be
conducted during the two nesting seasons following completion of fill placement as
follows.
i. The number of escarpments and their location relative to DNR-DEP 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 2 feet, 2 to 4 feet, and 4 feet or higher) as well as the
maximum height of all escarpments.
i. Escarpments that interfere with sea turtle nesting or that exceed 18 inches in height
for a distance of 100 feet shall be leveled to the natural beach contour by April 15.
Any escarpment removal shall be reported relative to R -monument.
ii. Any escarpments that exceed 18 inches in height for a distance of 100 feet shall be
leveled to the natural beach contour by April 15. 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 feet, the FWC shall be contacted
immediately to determine the appropriate action to be taken. Upon written
notification, the permittee shall level escarpments in accordance with mechanical
methods prescribed by the FWC.

Reports on all nesting activity shall be provided for the initial nesting season and for a
minimum of three additional nesting seasons. Monitoring of nesting activity in the three
seasons following construction shall include daily surveys and any additional measures
authorized by the FWC. 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. Data should be
reported separately for filled areas and nonfilled areas in accordance with the attached
Table. All reports should submitted by January 15 of the following year.
k. In the event a sea turtle nest is excavated during construction activities, all work shall
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.
1. Upon locating a dead, injured, or sick endangered or threatened sea turtle specimen,
initial notification must be made to the FWC at 1 -800 -DIAL FMP. 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 unnecessarily disturbed.
MONITORING REQUIRED:
1. Water Quality Monitoring
Borrow Site:
Parameter: Turbidity - Nephelometric Turbidity Units (NTUs)
Frequency: Every six hours during dredging.
Background: At least 150 meters upcurrent from the dredge site, outside of any visible
turbidity plume. Samples shall be collected from the surface and 1 meter above the bottom.
Compliance: No more than 150 meters downcurrent from the dredge site, in the densest
portion of any visible turbidity plume. Samples shall be collected from the surface and 1
meter above the bottom.
Beach Nourishment Site:
Parameter: Turbidity - Nephelometric Turbidity Units (NTUs)
Frequency: Every six hours during dredging.
Permittee: Village of Key Biscayne
Permit No.: 0160856-001-JC
Page 14 of 16
Background: At least 150 meters upcurrent from the discharge point, outside of any
visible turbidity plume. Samples shall be collected from the surface and 1 meter above the
bottom.
Compliance: No more than 150 meters downdrift from and no more than 150 meters
offshore of the discharge point within the densest portion of any visible turbidity plume.
Samples shall be collected from the surface and 1 meter above the bottom.
Weekly summaries of all monitoring data shall be submitted to the Office of Beaches and
Coastal Systems and to the Southeast District Office within one week of analysis with
documents containing the following information: (1) permit number; (2) dates and times of
sampling and analysis; (3) a statement describing the methods used in collection, handling,
storage and analysis of the samples; (4) a map indicating the sampling locations; and (5) 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) wave height.
The compliance locations given above shall be considered the limits of the temporary mixing
zone for turbidity allowed during construction. If monitoring reveals turbidity levels at the
beach compliance site greater than 29 NTUs aboEre the associated background turbidity
levels, construction activities shall cease immediately and not resume until corrective
measures have been taken and turbidity has returned to acceptable levels.
2. Biological Monitoring. The permittee shall submit a biological report within 90 days of
completion of the post -construction survey and each annual survey. The report shall
summarize the results of the following biological surveys, aerial photography, and mitigation
areas and identify any adverse impacts which would be attributable to the project. Each
report shall compare the current conditions to a) the pre -construction beseline survey, b) the
first post -construction survey, and c) any previous annual survey(s) (where applicable).
Each report shall contain an analysis and discussion of the video documentation in regards
to any burial, sedimentation, or trauma that has affected the seagrass, coral, sponges, or
other related biological communities.
a. Pipeline corridor: Underwater seagrass surveys of the pipeline corridor with video
documentation immediately prior to pipeline installation, immediately after pipeline
placement, within 30 days after pipeline removal, one year after pipeline removal, and
continue annually until the corridor has fully recovered. DGPS navigational coordinates

of the dives shall be referenced on the video transects and overlaid on recent aerial
photography.
b. Nourishment area - in situ scuba surveys. Measurements of the edge of the seagrass in
relation to DEP reference monuments shall be taken at 250 -ft. intervals between R-101
through R-109. The location of the edge of the seagrass beds shall be determined (with
at least 1 ft. accuracy) prior to fill placement, within 30 days after construction, and at
one-year post -construction.
c. Nourishment area - aerial photography. Flight -dated aerial photography shall be taken
during the summer at one-year following placement of fill and submitted to the
Department biannually (every other year) for the duration of the permit. The aerials
must be color, vertical aerial photographs, controlled and rectified at a scale appropriate
for post -production digitilization and a scale and clarity sufficient to delineate seagrass
areas. The flight line shall include all of the beach fill, pipeline corridor, borrow areas,
and mitigation areas. The permittee may use existing aerial photography being conducted
by the permittee, County or State if it meets the criteria listed above.
3. Hydrographic Monitoring. A hydrographic monitoring program shall be conducted for a
minimum of three (3) years following completion of construction. The permittee may
incorporate the requirements of this monitoring plan into existing monitoring programs being
conducted. The hydrographic monitoring program shall include the following:
a. Beach and offshore profile surveys shall be conducted immediately prior to sand
placement, immediately following completion of the project, and annually thereafter.
Profiles shall be surveyed at DEP reference monuments R-100 through R-113. The
profile alignments shall be identical to the azimuths previously established for each
monument. All beach profiles shall extend from the monument at least 1,500 feet
seaward and out to the depth of closure if greater. Additional surveys may be required
following a major storm as determined by the Department.
b. The permittee shall submit an engineering report and the monitoring data to the Office
of Beaches and Coastal Systems within 90 days of completion of the post -construction
survey and each annual survey. The survey data should be submitted on floppy disk in
an ASCII format stored according to the department's standards for file structure
(contact the Office staff for additional information on specific requirements). The
report should summarize the performance of the beach fill project, identify erosion and
accretion patterns within the project limits and along the adjacent shorelines, verify the
analyses that were conducted in the development of the design of the project, and
identify any adverse impacts, which would be attributable to the project. Appendices
should include plots of survey profiles and graphical presentations of volumetric and

shoreline position changes for both the monitoring area and at each profile survey.
Results should be analyzed for changes since the end of 'construction and between
annual surveys.
Monitoring reports shall be submitted to the Office of Beaches and Coastal Systems in
Tallahassee and the Department's Southeast District office in West Palm Beach. Failure to
submit reports in a timely manner constitutes grounds for revocation of the permit. When
