3.00 ABSTRACT
Great St. Jim, LLC is seeking to construct two docks, one of which is a combination
dock/ barge landing, and a temporary barge landing to provide access to Great St. James
Island.
There is currently a small pile-supported dock located within Shallow Bay on the north
side of the island. The bay is very shallow and vessels accessing the dock have damaged
the shallow seagrass beds within the bay. At one time, there had been a concrete
bulkhead at the shoreline with a small floating dock. The previous owner submitted an
application for the existing dock which was approved by DPNR's Division of Coastal
2
EFTA00802727
Zone Management but was not approved by the U.S. Army Corps of Engineers due to
objections by National Marine Fisheries because of the shallowness of the bay. The dock
was constructed by the previous owner despite not receiving the federal permit and
notices were issued by the USACE requesting the removal of the unpermitted structure.
The dock however was never removed. The applicant understands the issues with the
existing dock and is proposing to remove the dock as soon as another dock is constructed
and usable.
A detailed study was done around the entire island to determine suitable locations for
dock location. All ESA listed corals were located and docks and barge landings were
designed to avoid these corals.
A temporary barge landing is being proposed on the northwestern facing beach. This site
is to the west of the salt pond and the associated wetlands. This a shoreline ramp which is
25 feet (ft) wide and 40ft in length extends to the Mean Water Line. The landing is free
of both coral and seagrass colonization. The landing is excellent for short term transfer of
material or equipment. The site is well protected from normal wave action but is
periodically impacted by wave action from ferries which travel through current cut
between Great St. James and St. Thomas. The wakes from these vessels make it an
unattractive site for mooring a barge for any length of time at the site. This landing can be
quickly constructed and utilized while the combination dock and barge landing on the
southeastern side of the island is constructed.
The western dock is proposed on the northern end of Christmas Cove. Historically there
was a dock in this location and there are still old concrete piles lying in the shallows of
this site. The proposed dock will be 10ft in width and 195ft in length extending 187ft
from mean low water (MLW) and 193ft from mean high water (MHW). The dock
extends beyond the nearshore hardbottom to a depth of 15ft out in the uncolonized sand
to allow for safe dockage for deeper vessels.
The southern dock is located off the point closest to Little St. James. The dock is "L"
shaped and is 20ft wide (to allow for barge landing) and 150ft in length extending 141ft
from MLW and I48ft from MHW, the "L" then turns east and extends 100ft by 20ft. A
wave attenuating/reef creating system is proposed beneath the dock which will allow for
more protected docking inside the dock when seas from the south are rough. The dock
has 9ft of water depth of the southern end and 711 to 8ft on the inside of the "L". The
dock has been designed so that barges can approach and land on the end of the dock
while vessels can dock along the "L".
After the hurricane Irma in 2017 the owner of the Great St. James assisted many of his
employees and their families who had lost their homes and housed people on the island.
In order to bring in emergency supplies, two small barge ramps were created near the
locations of both proposed docks; one in Christmas Cove and one off the closest point to
Little St. James. Both consisted of coral rubble and boulders pushed out into the water
approximately 10ft. and both were 15ft. wide. These were noticed by the USACE during
3
EFTA00802728
aerial surveillance and the USACE requested the removal of the structures as well as the
removal of some fill material which was deposited into the fringing wetland area while
creating access to the southern emergency ramp.
The southern ramp has been removed and the fill has been removed from the wetland
area and white mangrove seeds have been being spread in the wetland and seedlings are
beginning to sprout.
The applicant is requesting that he be allowed to keep the emergency ramp in Christmas
Cove until such time a permit is granted for the proposed barge ramp. This will facilitate
the bringing of materials and supplies to the island until such time a permanent ramp can
be built.
4.00 STATEMENT OF OBJECTIVES SOUGHT BY THE PROPOSED PROJECT
Great St. Jim, LLC is proposing to construct a temporary barge landing and an access
dock on the western side of the island to be used for worker and guest access to the island
and a combination barge landing/dock on the southeast side of the island on the point
closest to Little St. James. The existing dock in Shallow Bay will be removed as soon as
one of the docks is functional. The applicant is requesting to keep the emergency rubble
ramp in Christmas Cove until such time that the proposed barge landing can be permitted
and constructed.
5.0 SUMMARY OF PROPOSED ACTIVITY
Great St. Jim, LLC is seeking to construct two docks, one of which is a combination
dock/barge landing, and a temporary barge landing to provide access to Great St. James
Island. A detailed study was done around the entire island to determine suitable locations
for the dock locations and the sites with the least environmental impact were chosen.
A temporary barge landing is being proposed on the northwestern facing beach. This site
is to the west of the salt pond and the associated wetlands. This a shoreline ramp which
is 25 feet (ft) wide and 40ft in length extends to the Mean Water Line. Two bollards will
be placed to either side of the ramp and two moorings will be installed 75ft offshore on
either side of the ramp in just over 7ft of water depth. The mooring will be installed
using helix anchors and will use floating lines will be used to avoid seafloor disturbance
when the moorings are not in use. The landing is free of both coral and seagrass
colonization. The landing is excellent for short term pick up and drop off of material or
equipment. The site is well protected from normal wave action but is periodically
impacted by wave action from ferries which travel through current cut between Great St.
James and St. Thomas. The wakes from these vessels make it an unattractive site for
mooring a barge for any length of time at the site. This landing can be quickly
constructed and utilized while the combination dock and barge landing on the
southeastern side of the island is constructed.

EFTA00802729
The western dock is proposed on the northern end of Christmas Cove. Historically there
was a dock in this location and there are still old concrete piles lying in the shallows of
this site. The proposed dock will be 10ft in width and 195ft in length extending 187ft
from mean low water (MLW) and 193ft from mean high water (MHW). The dock will
connect to an access slab 12ft long and 2' thick. All the ESA listed coral species within
the area were located and the dock footprint avoids all ESA listed species. The dock
extends beyond the nearshore hardbottom to a depth of 15ft out in the uncolonized sand
to allow for safe dockage for deeper vessels.
The southern dock is located off the point closest to Little St. James. Again, all of the
ESA corals were located, and the dock was designed to avoid these corals. The dock is
shaped and is 20ft wide (to allow for barge landing) and 150ft in length extending
141ft from MLW and 148ft from MHW, the "L" then turns east and extends 10011 by
20ft. A wave attenuating/reef creating system is proposed beneath the dock which will
allow for more protected docking inside the dock when seas from the south are rough.
The dock has 9ft of water depth of the southern end and 7ft to 8ft on the inside of the
"L". The dock has been designed so that barges can approach and land on the end of the
dock while vessels can dock along the "L".
The existing dock in the shallow northern bay will be removed as soon as one of the other
two docks is functional. The dock will have the decking removed, and then the stringers
and pile caps will be disassembled. This will all be done by workers from the shore.
Once only the piles remain, a shallow draft barge will come into the bay and pull the piles
out. If for some reason the piles cannot be pulled they will be cut off by commercial
divers at the mudline.
As soon as the proposed barge landing can be constructed the applicant will remove the
emergency ramp from Christmas Cove. This will be done from the shoreline using a
backhoe which will pull the cobble back on to the beach and spread it out along the back
beach. The larger riprap boulders will be taken inland to use in landscaping.
5.0Ia Purpose of Project
The purpose of this application is to provide access to the island of Great St. James.
Great St. Jim, LLC is proposing to construct a temporary barge landing to be used during
the construction of the other docks, an access dock on the western side of the island to be
used for worker and guest access to the island, and a combination barge landing/dock on
the southeast side of the island on the point closest to Little St. James. The existing dock
in Shallow Bay and emergency ramp in Christmas Cove will be removed as soon as one
of the docks and proposed barge ramp is functional.

7
EFTA00802732
The marine habitats around Great St. James have abundant coral and seagrass resources.
There are numerous ESA listed corals species near the proposed dock locations.
Acropora palmata, Acropora. cervicornis, Orbicella annularis, Orbicella franksi and
Orbicella faveolata as well as Dendrogyra cylindrus are found off all the beach from
which the proposed docks and barge landings are planned. At the northern temporary
barge landing site, these corals are located primarily to the west in an area of coral
boulders and coral rubble. However, there are several small A. palmata and several 0.
annularis located on the shoreline cobble which extends out to a depth of 6.5ft. The
presence of these species as well as several non-ESA listed Porites astreoides has
dictated the location of the ramp. The proposed temporary barge landing position avoids
all coral and seagrass resources.
Location of the western dock has a cobble beach between two areas of emergent bedrock
and boulders. A. paknata occur on the emergent bedrock to the north. Offshore the
seafloor quickly gives way to exposed pavement. There is a long linear depression right
offshore and an old piling lies within this area. The fractured pavement then extends to
approximately 11.5ft of depth over the next 100ft heading offshore. The area has some
widely-scattered boulders and patchy coral colonization. There are scattered ESA corals
including Orbicella and Dendrogyra. During the first survey, there was a very large A.
palinata colony immediately seaward of where the old piling lay near shore. However,
upon the next visit by the island it was noted that an old boat was tied nearshore
apparently attached to the old piling. During a dive, several weeks later it was noted that
the boat was gone and the large A. cervicornis had been badly broken. The location of all
the ESA species has dictated the location of the dock. Approximately 75 corals will
require relocation to minimize impact, but no listed corals will need relocation.
The southern dock also extends from a cobble beach which gives way to rock pavement
and has emergent bedrock and boulders on either side of the beach. There are Acropora
colonies to the east and farther to the south on the bedrock and boulders. There are
Orbicella and Dendrogyra within the embayment and their locations have dictated the
location of the dock. The dock avoids all ESA listed corals but will require the relocation
of approximately 75 corals.
This southern dock will include a combination wave attenuator and reef building system.
A mitigation plan has been prepared and is found in Appendix B.
Because of the rock occurring in the area, some of the pilings may require socketing and
if this is required special water quality measures will be taken. If at all possible a vibra-
hammer will be used to drive the piles. A water quality monitoring program has been
proposed and the plan is found in Appendix C.
The area is known habitat to protect sea turtles and marine mammals and as such
NOAA's Sea Turtle and Smalltooth Sawfish Construction Conditions will be followed as
well as NOAA's Vessel Strike Avoidance Measures and Reporting for Mariners.

EFTA00802733
The property contains 6 salt ponds. The wetland around the salt ponds have been
delineated and the delineations were approved by the U.S. ACOE during a previous
application for development of the island. This delineation is more than 5 years old, but
no wetland disturbance will occur as a result of this project.
The island is known to be habitat to the St. Thomas Tree Boa that is a listed rare and
endangered species. The boa as well as another species of snake have been seen during
the field studies. There will be special corridors and preservation areas set aside on the
island for these species. The access ways to the western and southern docks already
exist, but the branch that will need to be developed to the temporary barge landing will be
cleared by hand to limit impacts to the tree boas. A tree boa mitigation plan is found in
Appendix D.
Both emergency barge ramps consisted of cobble and boulders pushed out from the
shoreline to create landings so that the barge would have sufficient water depth to land
the supplies. Both ramps were pushed out over the uncolonized coral rubble and neither
extend deep enough to encounter coral resources. No turbidity impacts were noted
during the survey of the ramps. The southern ramp has since been removed.
5.OIc Method of Construction
The temporary barge ramp will be the first feature constructed. The landing slab will be
framed and poured from shore and the bollards will be installed near the shoreline. The
cobble will be excavated with a small machine and silt fencing will be placed seaward off
all excavation prior to any work. Divers utilizing a small boat will install the offshore
moorings. As soon as this ramp is in the emergency barge ramp will be removed. The
emergency barge ramp will be removed by backhoe from the shoreline. The cobble will
be pulled in and spread on the back beach. The riprap will be taken inland to use in
landscaping.
The western and southern docks will both be constructed from a barge. A vibratory
hammer will be used to drive all the piles if the hardness of the rock allows. If the rock
proves to be too hard, the piles will be socketed, placed, and grouted in. All corals will be
transplanted out of the footprint and area of impact prior to the start of construction and
all turbidity control will be installed prior to any in-water work that day. If rocketing is
required, seafloor length curtains will be used and monitored and not removed until water
quality within the curtains has fallen to acceptable limits. All corals within the curtain
limits will be removed to prevent damage by settling sediments. Once the pilings have
been placed, re-enforcing steel will be placed, and concrete poured. Turbidity controls
will be installed, and water quality monitoring will occur during all concrete pouring.
Once the piles are completed the pile caps and decking will be placed.
1O
EFTA00802734
Access slabs will be constructed from shore and silt fencing will be placed seaward of all
excavations.
The existing dock will be removed as soon as one of the access docks is functional. The
decking and pile caps will be removed from shore. The pilings will be pulled by a small
barge and if the pilings proved to hard to pull they will be cut off at mudline.
5.0Id Provisions to Limit Site Disturbance
The dock locations have been located to minimize impact on the marine environment by
avoiding all ESA listed corals and seagrass beds. Corals which cannot be avoided will be
relocated out of the footprint and potential area of impact and turbidity control and water
quality monitoring will be implemented. The branch of the road to the temporary barge
landing will be first cleared by hand to minimize impact to the VI Tree Boa. A Tree Boa
protection plan is found in Appendix D.
5.00e Sedimentation Control Methods to be Implemented.
Silt fencing will be placed seaward of all upland excavation and construction. Turbidity
bathers will be installed around all areas of in-work, including pile driving and concrete
pouring overwater. If pile socketing is required two rows of turbidity bathers will be
installed and these curtains will be seafloor length. These curtains will be maintained
until the interior water quality has fallen to acceptable levels.
5.00f Schedule for Construction Activities and Implementation of Sediment Control
Measures
Silt fencing will be installed prior to any upland excavation and maintained throughout
construction. All construction will be occurring in cobble areas without vegetation, so
fencing will be maintained until such time no exposed soil is within the area.
Silt fencing will be installed during the new access road clearing and maintained until
such time the roadway is stabilized.
Turbidity barriers will be installed before any in-water work and maintained until interior
water quality is within acceptable levels. Double turbidity bathers will be required if pile
socketing is required.
5.00g Maintenance of Sediment and Siltation Control Measures
All silt fencing and turbidity bathers will be inspected and maintained through the
construction period. Silt fencing will be inspected daily even when no construction is in
progress (over weekends/holidays). Turbidity bathers will be monitored throughout the
II
EFTA00802735
day and will be repaired and adjusted as necessary as part of the water quality monitoring
plan. Curtains will be maintained throughout the day and removed or secured as
necessary when no in-water work is ongoing.

6.00 ENVIRONMENTAL SETTING AND PROBABLE PROJECT IMPACTS
6.01 Climate and Weather
Prevailing Winds
The Virgin Islands lie in the "Easterlies" or "Trade Winds" which traverse the southern
part of the "Bermuda High" pressure area, thus the predominant winds are usually from
the east-northeast and east (IRF, 1977). These trade winds vary seasonally (Figure
6.01.1) and are broadly divided into 4 seasonal modes: I) December to February; 2)
March to May; 3) June to August; and 4) September to November. Below are the
characteristics of these modes as taken from Marine Environments of the Virgin Islands
Technical Supplement No. I (IRF, 1977).
December - February
During the winter the trade winds reach a maximum and blow with great regularity from
the east-northeast. Wind speeds range from eleven to twenty-one knots about sixty
percent of the time in January. This is a period when the Bermuda High is intensified
with only nominal compensation pressure changes in the Equatorial Trough. The trade
winds during this period are interrupted by "Northerners" or "Christmas Winds" which
blow more than twenty knots from a northerly direction in gusts from one to three days.
Such outbreaks average about thirty each year. They are created by strengthening of
high-pressure cells over the North American continent, which, in turn, allow weak cold
fronts to move southeastward over the entire Caribbean region. Intermittent rains, clouds
and low visibility accompany these storms.
March - May
During the spring, the trade winds are reduced in speed and blow mainly from the east.
Winds exceed twenty knots only thirteen percent of the time in April. The change in
speed and direction is the result of a decrease of the Equatorial Trough.
June - August
Trade winds reach a secondary maximum during this period and blow predominantly
from the east to east-southeast. Speeds exceed twenty knots twenty-three percent of the
time during July. The trend for increasing winds results from the strengthening of the
Bermuda High and a concurrent lowering of the pressure in the Equatorial Trough. Trade
winds during this period are interrupted by occasional hurricanes.
September - November
During the fall, winds blow mainly from the east or southeast and speeds reach an annual
minimum. Only seven percent of the winds exceed twenty knots in October. The low
wind speeds result from a decrease in the Equatorial Trough. During this period,
19
EFTA00802743
especially during late August through mid-October, the normal trade wind regime is often
broken down by easterly waves, tropical storms, and hurricanes.
Storm and Hurricanes
There are numerous disturbances during the year, especially squalls and thunderstorms.
These occur most frequently during the summer, lasting only a few hours, and causing no
pronounced change in the trade winds.
A tropical cyclone whose winds exceed 74 miles per hour is termed a hurricane in the
northern hemisphere, and significantly affects the area. These hurricanes occur most
frequently between August and mid-October (Figure 5) with their peak activity occurring
in September. The annual probability of a cyclone is one in sixteen years (Bowden,
1974).
Climate
No rainfall data is available for Great St. James. However, based on the vegetation on the
island the island which is dry adapted, it is probable that the island gets between 36-45
inches of rainfall a year. Rainfall usually occurs in brief, intense showers of less than a
few tenths of an inch and major rainfall events are associated with weather systems
(USGS 1998). The Virgin Islands have no sharply defined wet season. The wettest
period generally is from September to November, and the driest period is from January to
June (USGS 1998). The Cruz Bay which is the closest monitored station receives
between 39 inches of rainfall annually. The average rainfall received between 1972 and
2012 is found in the table below.

The difference between the mean temperatures of the coolest and warmest month is only
5 to 7 degrees F. The highest temperatures August or September and the lowest are in
January or February. The highest average daytime temperature in the warmest months is
about 88 degrees F, and in the coolest months is in the low 80's. Nighttime lows are
usually in the mid 70's during the warmer months and in the high 60's during the cooler
months (USGS 1998). In general, air temperature in the Virgin Islands ranges between
77 degrees and 85 degrees.

6.02 Landforms, Geology, Soils, and Historic Use
GEOLOGY OF ST. THOMAS, ST JOHN AND SURROUNDING CAYS
The Virgin Islands are near the northeastern corner of the present Caribbean Plate, a
relatively small trapezoidal-shaped plate that is moving eastward relative to the North and
South American continents carried on the American plate. The arc of the Lesser Antilles
is an active volcanic arc above a subduction zone in which the Atlantic oceanic crust of
the American Plate is carried downward under the Caribbean Plate. The closest volcano
to the Virgin Islands that is still active is Saba, about 160 km. to the east.
St. John is 7 miles long and 3 miles wide for a total of 12,000 acres or 19 square miles.
The oldest rocks of St. John are submarine lavas (keratophyre and spilite), beds of
volcanic debris and chert. Associated intrusive rocks of the Water Island Formation is
overlain by andesitic volcanic and volcanoclastic rocks of the Louisenhoj Formation
which underlies the island of St. Thomas to the east and much of the northwestern portion
of St. John. Donnelly (1966) suggested that the Louisenhoj Formation was deposited
unconformably on the Water Island Formation after a period of emergence, tilting and
erosion, on the slopes and environs of a subaerial volcanic island located roughly
between St. Thomas and St. John, an area now occupied by Pillsbury Sound. The
youngest layered deposits on St. Thomas are volcaniclastic rocks of the Tutu Formation.
Fossils contained in the Tutu Formation suggest that those deposits are of the Early
Cretaceous (Albain) Age (Donnelly et. al. 1971). It appears that all of the volcaniclastic
rocks of St. Thomas and St. John were deposited in a relatively short period of time
spanning 10 to 15 million years approximately 100 million years ago (D. Rankin 1988).
23
EFTA00802747
GEOLOGY OF GREAT ST. JAMES
The island which lies off the eastern tip of St. Thomas is irregularly shaped, and has two
fault lines running across the island. The island is comprised of 162 acres and rises to an
elevation of 186 feet above sea level. The island is a part of the Water Island Formation
that was lain down in the Lower Cretaceous. The northern tip is tonalite, gabbro and
granite from the tertiary period, the north-western tip as well as the southeastern tip of the
island is basalt, and the southwestern tip is undivided, mostly keratophyra. The central
portion of the island and the northeastern point is part of the Louisenhoj Formation. The
shorelines are a combination of sandy beach, cobble beach and shear rocky cliffs. There
are 6 salt ponds on the island.
SOILS OF THE PROJECT SITE
The Custom Soil Survey of the Unites State Virgin Islands has classified 6 soil types on
the islands of Great St. James. Cinnamon Bay gravelly loam (CgC), 5 to 12 percent
slopes, occasionally flooded is usually found on alluvial fans and terraces adjacent to
volcanic uplands. It has a surface layer which is 0 to 5 inches deep that is a very dark
grayish brown gravelly loam, the subsurface is 5 to 10 inches deep and is a dark brown
gravelly loam. Redhook extremely stony sand (RdB), 0 to 5 percent slopes, rubbly,
rarely flooded is usually found on coast beaches that are composed of calcareous sand. It
has a surface layer 0 to 7 inches deep of dark brown extremely stony sand, underlain with
7 to 10 inches of brown very stony and 10 to 16 inches of very pale brown very gravelly
sand below which is 16 to 60 inches of white very gravelly sand. Salt flats ponded
(SaA) consist of area of unvegetated saline flats, saline marshes and salt ponds. The soils
are very deep and poorly drained, strongly saline and frequently ponded for very long
periods. Southgate-Rock outcrop complex (SrE), 20 to 40 percent slopes is found on
the summits and side slopes of volcanic hills and mountains. It has a surface layer of 0 to
5 inches of brown gravelly loam and a subsoil of 5 to 10 inches of brown very gravelly
loam underlain by 10 to 17 inches of weathered igneous bedrock and 17 to 60 inches of
unweathered igneous bedrock. Southgate-Rock outcrop complex (SrF), 40 to 60
percent slopes is found on the summits and side slopes of volcanic hills and mountains. It
has a surface layer of 0 to 5 inches of brown gravelly loam and a subsoil of 5 to 10 inches
of brown very gravelly loam underlain by 10 to 17 inches of weathered igneous bedrock
and 17 to 60 inches of unweathered igneous bedrock. Solitude gravelly fine sandy loan
(SoA), is found in areas that are adjacent to saline marshes, flats and salt ponds and are a
mixture of terrestrial and marine sediments.

HISTORIC USE
The archeological survey found no evidence of prehistoric habitation. There are no
structures shown on the island before 1760 on any of the historic maps. The island is
reported to have been under cultivation since the 1760. Around 1770, a cotton plantation
was established and cotton was cultivated until approximately 1815. Great St. James was
continuous occupied between 1760 and 1911. Today there is a house and complex
located off the northern bay which is often referred to as Shallow Bay
ADVERSE SITE CONDITIONS
The island is protected by its location between St. Thomas and St. John and the
surrounding cays. The northern temporary barge landing is protected by the other cays to
the north, and St. Thomas and St. John to the west and east. Waves do attenuate in
Pillsbury Sound and the area can be affected by large seas and swells. However, there
are no offshore structures other than the buoys and barges using the site should be
moored no more than a couple of hours.
Under normal sea conditions the Christmas Cove Dock and the Southeastern Dock/Barge
Landing are well protected by their locations in relation to the prevailing seas which are
25
EFTA00802749
usually from the east, southeast or northeast. During storms and during some periods of
the winter, seas can approach from the southwest. The Christmas Cove dock could be
effected by waves approaching between 220° to 250° and the Southwest dock would be
effected by waves coming from 210' to 240'. Waves occur from this direction primarily
during storm events. When seas become extremely rough or storms approach vessels
would be taken to more protected anchorages.
All three sites lie with area VE elevation 8ft where FEMA has determined that the 100-
year flood elevation with velocity will be 8ft as shown on FIRM maps 45 and 30 below.
Figure 6.02.2. FEMA FIRM Map Panel 45 of 94.
26
EFTA00802750
Figure 6.02.3 FEMA FIRM Map Panel 30 of 94.
The U.S. Virgin Islands lie in one of the most earthquake prone areas of the world, and
are susceptible to ground shaking, earthquake-induced ground failures, surface fault
ruptures and tsunamis (tidal waves) (Hays, 1984). The activity is mostly associated with
large-scale tectonic activity or faulting, originating in the Anegada Trough to the
northeast of the islands. The trough and its related scarp apparently were thrown up by
block faulting during the late Pliocene or early Pleistocene. It is oriented generally
northeast to southwest, separating St. Croix from Puerto Rico and the other Virgin
Islands. Based on shallow focus earthquakes, the Anegada Fault Trough is estimated to
be more than 400 miles in length. There are indications that strike slip movement is
occurring, with St. Croix shifting northeast relative to Puerto Rico (Puerto Rico Water
Authority 1970). The year 2018 marks the 151th anniversary of the last major
earthquake in the islands. This quake, which occurred on November 18, 1867 had an
identified intensity of VIII on the Modified Mercalli Scale. Earthquakes of this
magnitude have generally been associated with epicentral ground accelerations of
between 0.05 and 0.35 gravities. Since the 1868 quake, there has been continuous low
intensity activity, all below 6.0 Richter. Thousands of tiny earthquakes are encountered
every year on the island.
27
EFTA00802751
IMPACT OF SITE GEOLOGY ON THE DOCK
The site geology will have little impact on the construction and placement of the
temporary barge landing. Both other docks will be impacted by the site geology which
will dictate how the pilings can be installed. It is probable that the pile in the pavement
areas will have to be socketed. Once beyond the pavement a vibratory hammer can be
utilized.
IMPACT OF THE PROJECT ON GEOLOGICAL RESOURCES
No dredging or filling is proposed, therefore there will be negligible impact on the
geology of the area. The emergency ramp will be removed as soon as the proposed barge
landing is constructed and the shoreline will be restored to pre-ramp conditions.
6.03 Drainage, Flooding, and Erosion Control
6.03a Impacts of Terrestrial and Shoreline Erosion
The project includes the construction of 3 landing or access pads on cobble beaches
between rocky headlands. These pads are all limited in size the largest being just over
1000sqft. Due to the small size of these introduced impervious surfaces none should
result in any notable change in terrestrial runoff. Both docks are pile supported and in
areas of rocky or cobble beaches. Neither dock site has sand deposition on the beach and
the cobbles found on both beachesare moved by wave action rather than littoral transport.
The construction of the docks should not result in any shoreline erosion.
6.03b Relationship of the Project to the Coastal Flood Plain
All three sites lie with area VE elevation 8ft. where FEMA has determined that the 100-
year flood elevation with velocity will be 8ft as shown on FIRM maps 45 and 30
provided in Section 6.02.
6.03c Presence and Location of any Critical Areas and Possible Trouble Spots
The island of Great St. James is within the Vessup Bay/ East End Red Hook Area of
Particular Concern (APC) (Figure 5.01.1). The Vessup Bay/Red Hook APC is located on
the eastern end of St. Thomas and includes Nazareth, Muller, Vessup, Red Hook, Great
Bay, Cowpet Bay, Cabrita, Beck and Water Point, Great St. James, Little St, J, and Dog
Island.

• Fishing with hook and line
The marine habitats around Great St. James have abundant coral and seagrass resources.
There are numerous ESA listed corals species near the proposed dock locations.
Acropora palmata, Acropora. cervicornis, Orbicella amzularis, Orbicella franksi and
Orbicella faveolata as well as Dendrogyra cylinders are found off all the beach from
which the proposed docks and barge landings are planned. At the northern temporary
barge landing site, these corals are located primarily to the west in an area of coral
boulders and coral rubble. However, there are several small A. palmata and several 0.
amiularis located on the shoreline cobble which extends out to a depth of 6.5ft. The
presence of these species as well as several non-ESA listed Porites astreoides has
dictated the location of the ramp. The proposed temporary barge landing position avoids
all coral and seagrass resources.
Location of the western dock has a cobble beach between two areas of emergent bedrock
and boulders. A. palmata occur on the emergent bedrock to the north. Offshore the
seafloor quickly gives way to exposed pavement. There is a long linear depression right
offshore and an old piling lies within this area. The fractured pavement then extends to
approximately 11.5ft of depth over the next 100ft heading offshore. The area has some
widely-scattered boulders and patchy coral colonization. There are scattered ESA corals
including Orbicella and Dendrogyra. During the first survey, there was a very large A.
pabnata colony immediately seaward of where the old piling lay near shore. However,
upon the next visit by the island it was noted that an old boat was tied nearshore
apparently attached to the old piling. During a dive, several weeks later it was noted that
the boat was gone and the large A. cervicornis had been badly broken. The location of all
the ESA species has dictated the location of the dock. Approximately 75 corals will
require relocation to minimize impact, but no listed corals will need relocation.
31
EFTA00802755
The southern dock also extends from a cobble beach which gives way to rock pavement
and has emergent bedrock and boulders on either side of the beach. There are Acropora
colonies to the east and farther to the south on the bedrock and boulders. There are
Orbicella and Dendrogyra within the embayment and their locations have dictated the
location of the dock. The dock avoids all ESA listed corals but will require the relocation
of approximately 75 corals.
This southern dock will include a combination wave attenuator and reef building system.
A mitigation plan has been prepared and is found in Appendix B.
Because of the rock occurring in the area, some of the pilings may require socketing and
if this is required special water quality measures will be taken. If at all possible a vibra-
hammer will be used to drive the piles. A water quality monitoring program has been
proposed and the plan is found in Appendix C.
The area is known habitat to protect sea turtles and marine mammals and as such
NOAA's Sea Turtle and Smalltooth Sawfish Construction Conditions will be followed as
well as NOAA's Vessel Strike Avoidance Measures and Reporting for Mariners.
The property contains 6 salt ponds. The wetland around the salt ponds have been
delineated and the delineations were approved by the U.S. ACOE during a previous
application for development of the island. This delineation is more than 5 years old, but
no wetland disturbance will occur as a result of this project.
The island is known to be habitat to the St. Thomas Tree Boa that is a listed rare and
endangered species. The boa as well as another species of snake have been seen during
the field studies. There will be special corridors and preservation areas set aside on the
island for these species. The access ways to the western and southern docks already
exist, but the branch that will need to be developed to the temporary barge landing will be
cleared by hand to limit impacts to the tree boas. A tree boa mitigation plan is found in
Appendix D.
Both emergency barge ramps consisted of cobble pushed out from the shoreline and
boulders being placed around them to stabilize. Both extended approximately loft.
beyond the MHW line and both were approximately 15ft. wide. Both extended out over
uncolonized coral rubble so no corals were directly impacted. Neither barge landing
appeared to be creating turbidity impacts when they were surveyed. The southern ramp
has been removed and the applicant would like to keep the emergency ramp in Christmas
Cove until the proposed ramp is constructed.
6.04 Fresh Water Resources
There are no freshwater resources on the island of Great St. James. There is no potable
water use planned for either dock or the temporary barge landing.
32
EFTA00802756
6.05 Oceanography
6.05a Sea Bed Alteration
Great St. Jim, LLC is seeking to construct two docks, one of which is a combination
dock/barge landing and a temporary barge landing to provide access to Great St. James
Island. A detailed study was conducted around the entire island to determine suitable
locations for the dock locations and sites with the least environmental impact were
chosen.
A temporary barge landing is being proposed on the northwestern facing embayment.
The barge landing can be quickly constructed and utilized while the combination
dock/barge landing on the southeastern side of the island is constructed. This site is to
the west of the sand pond and its associated wetlands. The landing includes a shoreline
ramp which is 25ft wide and 40ft in length extends to the Mean Water Line (MWL).
Two bollards will be placed to either side of the ramp and two moorings will be installed
75ft offshore on either side of the ramp in just over 7ft of water depth. This will allow
barges to moor rather than to use their props to stay in place and will minimize bottom
disturbance. The moorings will be installed using helix anchors and will use floating lines
as to not disturb the seafloor when not in use. The landing area is free of coral
colonization and just offshore there is very sparse seagrass colonization.
The western dock is proposed on the northern end of Christmas Cove. Historically there
was a dock in this location and there are still old concrete piles lying in the shallows of
this site. The proposed dock will be 10ft in width and 195ft in length extending 187ft
from MLW and 193ft from mean high water (MHW). The dock will connect to an access
slab which is 12ft xl2ft and the slab will be 2ft thick. All the ESA listed coral species
within the area were located with GPS and the dock footprint avoids the ESA listed
species. The dock extends beyond the nearshore hardbottom out to a depth of 15ft into
an area of uncolonized sand to allow for safe dockage for deeper vessels and minimum
impact by vessels to the seafloor. The dock will require sixty-six 12in diameter piles.
The southern dock is located off the point closest to Little St. James. The ESA corals
were located by GPS and survey and the dock was designed to avoid these coral species.
The dock is "L" shaped and is 20ft wide (to allow for barge landing) and 150ft in length
extending 141' from MLW and 148' from MHW, the "L" turns east and is 20ft wide and
100ft in length. A combination wave attenuating/reef creating system is proposed beneath
the dock which will allow for more protected docking inside the "L" when seas from the
south are rough. The dock has 9ft of water depth off the southern end and 7ft to 8ft on
the inside of the "L". The dock has been designed so that barges can approach and land
on the south end of the dock while vessels can dock along the "L". There will be 152
12in diameter dock piles and forty-three 12in diameter wave attenuator piles. The
attenuator/reef building piles provide substrate designed additional surface to allow
colonization by coral and sponge species.
33
EFTA00802757
After the hurricane Irma in 2017 the owner of the Great St. James assisted many of his
employees and their families who had lost their homes and housed people on the island.
In order to bring in emergency supplies, two small barge ramps were created near the
locations of both proposed docks; one in Christmas Cove and one off the closest point to
Little St. James.
Both emergency barge ramps consisted of cobble pushed out from the shoreline and
boulders being placed around them to stabilize. Both extended approximately 10ft.
beyond the MHW line and both were approximately 15ft. wide. Both extended out over
uncolonized coral rubble so no corals were directly impacted. Neither barge landing
appeared to be creating turbidity impacts when they were surveyed. The southern ramp

The Virgin Islands coastal areas are not subject to significant tidal ranges or tidal
currents. Due to the small size of the island, the sea flows around the island causing an
average tidal height of only a few inches and maximum change of only a little over a
foot. Only very narrow intertidal zones are found because of this lack of tidal amplitude
and the steepness of the island rising out of the sea. The tides around Great St. James are
primarily semi-diurnal in nature, with two cycles of high and two of low water every 24
hours. The second cycle is often indistinguishable. The mean tides range from 0.8f. to 1.0
ft and the spring tidal ranges reach up to 1.3ft (IRF 1977). There are no notable locally
driven tidal currents due to the lack of confinement within the area. NOAA has a tide
gauge in Charlotte Amalie which is a southern exposure which has been recording water
levels since 1975. The high tide recorded on September 18, 1989 (Hurricane Hugo) was
+3.35ft, and in 1995 during Hurricane Marilyn the Charlotte Amalie tide station recorded
the highest tide height 3.98ft above Mean Lower Low Water (MLLW). The lowest tide
recorded was on February 6, 1985 and was -1.44ft. The tidal ranges of the Charlotte
Amalie station are as follows:
Mean Higher High Water 1.09ft
Mean High Water 0.94ft
Mean Tide Level 0.54ft
Mean Sea Level 0.52ft
Mean Low Water 0.13ft
Mean Lower Low Water 0.0ft
There is also a Tide Station in Lameshure Bay, St. John (Station ID: 9751381), the station
is located at latitude 18° 19.0' N and longitude 64° 43.4' W and has a mean tidal range of
0.72 ft and a diurnal range of 0.82 ft.

The surface currents throughout the Caribbean are driven by the North Equatorial Current
that runs through the islands west-northwest and then joins the Gulf. These currents
change very little from season to season with the currents coming more from the south
during the summer months. Because of the shallowness of the Caribbean basin of less
than 1000m, mainly surface water from the Atlantic flows through the islands. The
westerly drift of the Caribbean Current sweeps into Pillsbury Sound from the Southeast,
seeking a way North through the barrier set up by the Cays to discharge along the North
Shore of St. Thomas and out into the Atlantic. The current flows past Great St. James in
a northwesterly direction. Due to the formation of the island and the normal water
movement into Pillsbury Sound from the south, there is frequently a strong southerly
current running between Great St. James and Little St. James and through Current Cut.
6.05C WAVES
The deep-water waves off Great St. James are primarily driven by the northeast trade
winds that blow most of the year (Figure 6.05.1). Waves average from 1 to 3ft from the
east, 42% of the time throughout the year (IRF, 1977). For 0.6% of the time easterly
waves reach 12ft in height. The southeasterly swell with waves one to twelve feet high
become significant in late summer and fall when the trade winds blow from the east or
when tropical storms and hurricanes pass the islands at a distance to the south. During
the winter months, long length, long period northern swells develop to a height of 1 to 5
feet. The USACE Hindcast Studies for buoys 61022 and 61025, the two buoys whose
waves patterns directly affect the island, show that a majority of the waves which
occurred approach from easterly directions.
6.05D MARINE WATER QUALITY
The dock locations all have excellent water quality. During baseline studies for the dock
construction on Little St. James, baseline samples taken between Little St. James and
Great St. James found turbidities to range from 0.27 NTU to 1.17 NTU under normal sea
conditions. Samples taken those previous studies are shown below.

The offshore waters are classified as Class B and the best usage of the water is listed as
the propagation of desirable species of marine life and for primary contact recreation
(swimming, water skiing, etc.). The quality criteria include, dissolved oxygen not less
than 5.5mg/1 from other than natural conditions. The pH must not vary by more than 0.1
pH unit from ambient; at no time, shall the pH be less than 7.0 or greater than 8.3.
Bacteria (fecal coliform) cannot exceed 70 per ml, and turbidity should not exceed a
maximum nephelometric turbidity unit of three (3) NTU.
IMPACT OF PROPOSED PROJECT
The temporary barge landing and docks will replace the use of the landing and dock in
Shallow Bay. Both frequently result in the suspension of sediment from the seafloor.
The upland construction associated with the docks and landing are minor and with proper
36
EFTA00802760
siltation control should not result in any impact to marine water quality. The placement
of pilings will probably require socketing and could impact water quality. A double set
of seafloor length turbidity bathers will be required, and all corals will be relocated out
the bather footprints. Bathers must be maintained until such time the interior water
quality is acceptable. If properly implemented and monitored the socketing should have
only a very short-term limited impact on water quality. A Water Quality Monitoring Plan
is proposed and is found in Appendix C. Once constructed, the docks and landing will
have negligible impact on water quality. The docking areas are all deep enough that there
should not be an issue with propwash.
The emergency barge ramp in Christmas Cove will be removed from the shore by
backhoe as soon as the proposed barge landing is operational. The cobble will be pulled
back onto the beach and spread across the back beach. The boulders will be taken inland
to use in landscaping. Minor turbidity may occur during the removal of the ramp.
Turbidity barriers will be placed round the ramp prior to removal. The water is shallow
enough that no corals should be impacted.
The use the docks by vessels will increase the potential for releases of hydrocarbons into
the marine environment through spills and exhaust. No fueling or maintenance will be
allowed on the docks. To mitigate potential spills, fuel spill supplies will be kept near the
base of the docks so that they can be deployed in the event a release occurs. No pumping
of bilges or live-a-boards will be allowed on the dock.

6.06 MARINE RESOURSES
Benthic Habitat Description
General
Sandy beaches, cobble beaches and steep rocky shorelines surround great St. James
Island. All three of the proposed dock and barge landing sites will extend from cobble
beaches. The northern shore where the temporary barge landing is proposed has cobble
which extends down to a depth of approximately 7ft and has sparse seagrass colonization
within the barge approach. There are scattered corals in the bay to the east and dense
seagrasses offshore beyond the landing site. The cobble within the landing site is only
colonized by fire coral. The emergent bed rock to both the east and west sides of the bay
are colonized by corals species including ESA corals.
The northern portion of Christmas Cove where the Access Dock is located has emergent
bedrock to either side of the small embayment which are colonized by coral and sponge
species. Rock pavement and scattered boulders extends offshore to a depth of I I.5ft
where it gives way to a sandy bottom. Corals and sponges colonize the rock pavement
and scattered boulders. There is seagrass off shore, but it begins beyond the terminus of
the proposed dock.
The southern facing dock is off a cobble beach between to rocky shorelines. There is
rock pavement extending off shore and then broken rock pavement further out. Corals
and sponges colonized the rock pavement.
ESA listed coral species are found at all three locations and the Nassau Grouper
(Epinephelus striatus) was seen off both the Christmas Cove and southern dock site.
After the hurricane Irma in 2017 the owner of the Great St. James assisted many of his
employees and their families who had lost their homes and housed people on the island.
In order to bring in emergency supplies, two small barge ramps were created near the
40
EFTA00802764
locations of both proposed docks; one in Christmas Cove and one off the closest point to
Little St. James.
Both emergency barge ramps consisted of cobble pushed out from the shoreline and
boulders being placed around them to stabilize. Both extended approximately 10ft.
beyond the MHW line and both were approximately 15ft. wide. Both extended out over
uncolonized coral rubble so no corals were directly impacted. Neither barge landing
appeared to be creating turbidity impacts when they were surveyed. The southern ramp
has been removed.
Methods
The NOS St. John and St. Thomas Habitat Map Tile 16 (Figure 6.06.1) of the Great St.
James area shows the colonized rock pavement and bedrock as well as the offshore
seagrass beds. The seagrass beds are not as continuous near the shoreline as shown, and
the offshore area at both Christmas Cove and the southern dock site are colonized
pavement rather than bedrock right off the cobble beaches and on the northern facing
beach the pavement doesn't extend completely across the bay as shown. Surveys were
done on Scuba and Acropora palmata and Acropora cerviconds, Dendrogyra cylindrus,
Orbicella annularis, Orbicella faveolata, Orbicella franksi, and Mycetophyllia ferox were
mapped so that they could be avoided. Habitat boundaries were marked with GPS and/or
by the surveyor for accuracy. Percent abundance was determined along transect lines and
utilizing a meter square.

Benthic Resources
Great St. James is located off Water Point on the eastern end of St. Thomas. This oddly
shaped island has a variety of shoreline types and six salt pond/wetland habitats. There is
a well-protected shallow northern bay where an existing dock is located. Shallow Bay is
colonized by seagrass which includes Thalassia testudinum, Syringodium filzfonne and
Halodule wrightii. Recently the sea vine Halophila stipulacea has colonized areas which
have been disturbed. The densest seagrass beds once lay near shore and to the east of the
dock. Over the last several years these beds have been highly disturbed. The peninsula to
the east of this point is surrounded by rocky headlands and is a very exposed
environment. The rocky cliffs extend below the sea surface and due to the intense wave
action, the shallowest areas are not colonized. By a depth of 8ft-10ft the rocky substrate
becomes colonized by a wide variety of corals and sponges. The slope is steep offshore
and the water reaches a depth of 40ft to 50ft relatively close to shore. The rocky slope
gives way to a cobble then sand bottom and there are sparse to moderately dense seagrass
beds that extend seaward. The rocky shoreline continues around to the south, with coral
colonized nearshore hardbottom and seagrass colonized sand and cobble further offshore.
There are two cobble beaches further to the south divided by a small rocky headland,
there is some colonized beach rock nearshore and shallow seagrass beds off shore. The
shoreline facing St. James Cut and the southern end of the island is rocky. This area has
limited coral colonization in the inner tidal zone giving way to an abundant diverse coral
community on the submerged rocky slopes. The rock is relatively steep with numerous
grottos, and caves, and gives way to a cobble/sand bottom at around 20ft to 25ft. There
are moderate to dense seagrass beds off shore. The Stragglers lay off the southern most
point of the cay, and like the southern shoreline of the island there is minimal
colonization in the inner tidal areas of the emergent rocks with coral colonization and
diversity increasing with depth. The western shoreline is well protected and is a
combination of rock and sandy beach. The water deepens much more gradually on this
side of the island. In the areas with rock along the shoreline are colonized by corals and
sponges. The less colonized inner tidal area is much less defined here due to the more
protected nature of the site. Within Christmas Cove there is a rock groin like structure
that extends into the bay near the center of the embayment. Offshore to the north of the
groin there is a small beach rock shelf and then a strip of uncolonized sand before sparse
to moderately dense seagrass beds begin. The site is currently used by boats anchoring
adjacent to the beach.
To the south of the groin there is a beach rock shelf with moderate coral colonization
which falls off to depth of over 6ft only 40ft from shore and there is a board area of
uncolonized sand out to a depth of 10ft before reaching the moderately dense seagrass
beds and open sandy plains. The shoreline becomes rocky again to the north along
Current Cut and the area is more subject to wave and current action. There is coral
colonization along the rocky shoreline and on the rock pavement that extends off shore.
The north-facing bay to the east of Current Cut is a mixture of cobble and rocky shoreline
with a small sandy beach in front of the salt pond. Where rock is present there is coral
colonization and in the open sandy areas there is moderate to dense seagrass colonization.

EFTA00802766
The temporary barge landing is located at the western end of the north-west bay. The
landing. The beach is cobble and the cobbles extend out to a depth of 7ft at the landing
site. The landing site contains some scattered Millepora complanata, but no hard-coral
species. There are scattered corals to the east in the cobble including a few Orbicella
annularis and Acropora pahnata. Porites astreoides is the most abundant coral in the
cobble to the east. The location for the barge ramp was chosen due to the presence of
corals and coral colonized boulders throughout the bay to the east. To the east in the bay
there are numerous Orbicella annularis, O. faveolata and Dendrogyra cylindrus as well
as other coral species. Offshore there are dense seagrass beds consisting of 77u2lassia
testudinum and Syringodium fihforme, however these are greater than the 75ft off shore
which the barge will extend while moored. There very sparse Syringodium colonization
within the barge approach, representing less than 5% bottom coverage.

The access dock in Christmas Cove is near the location of an old historic dock. The beach
is a mixture of sand and cobble. There is rock pavement extending offshore and there is
an area of cobbles in the center of this area which is uncolonized out to a depth of 5ft.
The rock pavement has various depressions and breaks and within one of these
depression is a pile from the old concrete dock. Beyond the depression, the water deepens
quickly out to a depth of 12ft. The rock pavement is colonized by Diplona strigosa, D.
labyrinthifonnis, Orbicella annularis, 0. franksi, Porites astreoides, P. porites,
Dendrogyra cylindrus, Gorgonia sp. and Millepora sp. and the sponges Aplysinafidva,
Amphimedon compressa and Ircinia sp. Coral colonization increases on either end of the
small embayment and with depth. Beyond the nearshore hard bottom, approximately
120ft off shore the bottom becomes sandy. There is a minimally colonized area before the
bottom begins to become colonized by Syringodiumfilifonne which slowly grades into a
mixed bed of Thalassia testitudium and Syringodium. The exotic seavine Halophila
stipulacea is also present. This seavine was not present in 2006.
There was a very large intact Acropora cerviconzis in the center of the bay just off the old
dock piling in the depression early in 2016. However, a boat moored on the old piling
and on a subsequent dive the Acropora was found completely broken. Pieces of this
Acropora remain. There are Acropora palmata in the shallows to the north of the
proposed dock location both on the cobble and bedrock.

The Access Docic/Barge dock is located in the bay closest to Little St. James. Like the
other two bays there is cobble on the shoreline which extends into the sea to 2ft to 4ft of
water depth. Offshore there is pavement with boulders and odd rock formation. The area
is colonized by scattered corals which are most abundant on the boulders. Orbicella
annulans, O. franksi, O. faveolata, Dendrogyra cylindrus, Porites astreoides, P. porites,
Diplona strigosa, D. clivosa. D labyrinthifonnis Gorgonia sp. and Millepora sp. and
sponges Aplysinafidva, Amphinzedon compressa andIrcinia sp. are present. Acropora
palrnata is present on the headlands to the east and south.
There are scattered boulders and broken pieces of bedrock offshore, most of which are
colonized by corals and sponge species.

Impact of Construction
The temporary barge landing has minimal in-water disturbance. The landing pad is
landward of MHW and only two moorings will be placed offshore. Moorings will be
placed with helix anchors and will utilize floating lines to minimize impact to the
seafloor. There is very sparse Syringodiwn coverage in the immediate approach and the
installation of the anchors should have a negligible impact. The barge will come into the
landing tie up to the bollards and pick up the moorings and cut off its engines to
minimize impact. The end of the barge will be in 7ft of water at the edge of the cobble
where the sand is uncolonized. By not using is engines to maintain position on shore the
impact to the seafloor and water quality should be minimal. The barge will not be in
place long enough to have a shading impact on the seafloor.
There are approximately 75 corals in the footprint of the Christmas Cove Dock and its
immediate impact area. The corals will be relocated to the hardbottom areas to the north
prior to any construction. A Coral Relocation and Transplant Plan is found in Appendix
B. The Christmas Cove dock will require sixty-six I2in pilings. It is probable that a least
1/2 of those will require socketing. Double turbidity barriers will be deployed, and water
quality monitored will be conducted during all in water work. Turbidity barriers will not
be opened or removed until interior water quality has settled to acceptable levels. All
corals will be relocated out of the area enclosed by the curtains so that they will not be
impacted by settling sediment. Turbidity barriers will be removed or secured when not in
use to limit impact to the surrounding benthos. If turbidity control is properly
maintained and monitored the impacts should be minimal. The dock has been designed
to extend out into the uncolonized sand and terminate before reaching the dense
Thalassia and Syringodiwn beds offshore. The seavine Halophila stipulacea may now be
in the footprint of the dock. During the initial surveys, it was well beyond the dock
footprint but has slowly been spreading into the uncolonized sand. The use of the dock
will introduce the potential for hydrocarbon releases from motorized vessels and from
their exhaust. This bay is already highly used by sail and motor vessels and the increased
potential for releases should not be significantly over what is currently present.
The southeastern dock/barge ramp will also impact approximately 75 corals in its
footprint and impact area. These corals will be transplanted onto the hard bottom areas to
the south. The dock will require one hundred and sixty-six 12" piles and forty three 12"
piles for the wave attenuators and reef building system. Many of the piles may require
socketing and the same procedures will be followed as described for the Christmas Cove
installation. If properly implemented impacts to water quality should be minimal. The
depths are such that the dock's use should not disturb the seafloor. The use of the dock
will introduce the potential for hydrocarbon spills from vessels and from the exhaust.
The locations of the docks have been made so that they avoid impact to ESA listed coral
species and provide the greatest depth possible while minimizing the size of the
structures.
48
EFTA00802772
The Emergency Barge Ramps
The ramps were constructed shortly after the passage of hurricane Irma on September 6,
2017. They were constructed of coral rubble and cobble from the beaches and boulder
riprap was used to stabilize the sides.
I Christmas Cove ramp. the ramp has slowly been deteriorating.
The southern emergency ramp has been removed and the shoreline restored.
49
EFTA00802773
Fortunately, neither ramp extend far enough offshore to impact coral resources and both
were on cobble. Neither ramp was noted as creating turbidity during several surveys.
The Christmas Cove ramp has somewhat deteriorated since it was constructed and the
cobbles are spreading into the surround cobble.
6.07 Terrestrial Resources
The application is for the development of a temporary barge landing and two docks. All
three structures have access pads or landing pads which will be constructed on cobble
beaches which are unvegetated. The access ways to both the Christmas Cove beach and
southeastern dock already exist and will not require additional clearing. Approximately
175' of access way must be cleared in order to access the temporary barge landing.
Flora
The island is a harsh dry windswept environment that supports a large variety of thorny
species. There are 6 wetlands, two of the wetlands are salt ponds surrounded by
monocultures of black mangroves (Avicenna genninans) and two of the wetlands are salt
ponds surrounded by buttonwood mangroves (Conocarpus erectus). One of the wetlands
is more depressional and is surrounded by manchineel (Hippomane manchineel). A plant
species list follows which provides the general location for each of the species
encountered during detailed terrestrial surveys in 2005 and 2006. Additional terrestrial
surveys were made in 2016, and while a notable amount of additional clearing had been
done the species on the island remain the same. Many of the plants were found in more
than one habitat. The plant communities can be divided into those on the most exposed
areas of the coastline, the beach community, the wetland communities, the windward
vegetation and the less exposed portions of the site. There is also a small landscaped area
from around the existing buildings on the site.
The locally listed rare and endangered Man:malaria nivosa was noted on the exposed
rocky cliffs within the exposed coastal vegetation. It was not as prevalent as Turks head
cactus. Malpighia woodinuyanna, another locally listed rare and endangered plant may
be present but was not seen during the surveys.

Fauna
The island has significant wildlife use. Deer, and goats were noted during the survey in
the dense bush in 2004 but only deer were noted in 2005 and 2006. Numerous mice
and rats were noted on every visit and did not seem afraid of humans. No rats were noted
in 2016.
Reptiles were abundant and tree anoles (Anolis cristatellus), grass anoles (Anolis
pulchellus), barred anoles (Anolis stratulus), dwarf geckos (Thecadactylus sp), and
common ground lizards (Sphaerodactylus macrolepis) were seen. Worm lizards
(Amphisbaena fenestrata) have been reported but were not encountered. Puerto Rican
racers (Alsophis portoricensis) were seen on every site visit including in 2016 and appear
in the highest density around the salt ponds. The St. Thomas tree boa (Epicrates monensis
granti) is also present and two were seen during the surveys in May of 2006. One in the
vegetation near the modem housing complex and one in the trees near Christmas Cove.
6.08 Wetlands
The U.S. Army Corps of Engineers defines wetlands as "those areas that are periodically
inundated or saturated by surface or groundwater at a frequency and duration sufficient
to support, and under normal circumstances do support, a prevalence of vegetation
typically adapted for life in saturated soil conditions. Wetlands generally include
swamps, bogs, marshes and similar areas." (U.S. Army Corps of Engineers, 1986).
In March 2004 Amy Claire Dempsey of Bioimpact, Inc., delineated the wetlands on the
island of Great St. James in accordance to the 1987 Wetland Delineation Manual.
52
EFTA00802776
Figure 6.08.1 The six salt ponds on Great St. James
POND 1
Pond 1 is located on the northeastern point of the island. The pond is surrounded by
cobbled beaches to the north and west and steep hillsides to the east. The southern
side has the gentlest rise from the pond and has the greatest area of wetland outside the
area that typically has standing water. Cobbles extend down into the pond on the two
beach sides and the cobbles have green stains. The pond has a monoculture of black
mangroves, A viennia genninans.
53
EFTA00802777
POND 1
POND 2
Pond 2 is located on the northwestern point of the island. The pond is surrounded by a
cobble beach to the north and steep hill sides to the south, east and west. There is a
rock wall built across the eastern corner of the pond. The pond is almost a monoculture
of black mangrove, Aviennia germinal's. Only a few white mangroves, Laguncularia
racemosa were encountered along the shore side. This wetland is closest to the
temporary barge landing. The access roadway is 100' from the edge of this wetland.
54
EFTA00802778
POND 2
POND 2
POND 3
Pond 3 is a depressional area off Christmas Cove on the western side of the island. It
is located to the north of a larger salt pond. This wetland is primarily surrounded by
manchineel (Hippomane manchineel). It appears that this pond only occasionally holds
water. There is a lot of dead wood within this depression.
POND 4
Pond 4 is located behind the cobble beach berm off Christmas Cove. The western side
of the pond is bordered by a cobble beach and cobbles spill down into the pond. The
northern, southern and eastern sides of the pond are bordered by steep hillsides. The
wetland forms a narrow strip around the pond. The pond is a monoculture of
buttonwood mangroves, Conocarpus erectus.
55
EFTA00802779
POND 4
POND 5
Pond 5 is located on the eastern side of the island behind a cobble beach. Its eastern
border is a mixture of sand and cobble spilling over from the beach, and the northern,
southern and western border are steep hillsides. The northern end of the pond has been
filled with coral rubble which was thrown over into the pond during stormd. The pond is
surrounded by buttonwood mangroves, Conocarpus erectus and the ground cover
Sesuvium portulacastrurn is present along the eastern side.
POND 5
56
EFTA00802780
POND 5
POND 6
Pond 6 is located to the south of pond 5 on the other side of a knoll. It is fringed by the
shoreline community on its eastern and northern sides. Steep hillsides surround the
pond to the south and west. White mangroves (Laguncularia racemosa) are the
dominant species surrounding the pond.
The southeastern landing is closest to this pond. The access road already exist and its use
will not impact the wetland.
Wetland Impact
The roadway to the southern landing site was elevated during the flooding associated
with hurricanes Irma and Maria and the subsequent heavy rains. The elevating of the
roadway resulted in fill being placed into the edge of the wetland and into the low lying
area adjacent to it.
Fill has been pulled back from the southern side of the wetland and the edges of the
wetland and low-lying area and stabilized with riprap. Large boulders covered with filter
fabric have been placed beneath the roadway to allow the flow of water to and from the
wetland. During periods of high seas water flows over the shoreline to the north and
flows across the neck of the peninsula in to the saltpond. This function has been restored.
57
EFTA00802781
White mangrove seeds have been scattered in the pond and seedling are being to grow.
These will be monitored and a report will be sent to the US Army Corps showing the
survival of 20 mangroves in April of 2019.
Figure 6.08.1 Areas of wetland Encroachment. The wetland is shown in green and the
areas of wetland encroachment are shown in red and the area fill into the drainage into
the wetland is shown in blue.
The fill material has been completely pulled out of the wetland and the ground restore to
the proper elevation.
58
EFTA00802782
The fill has all been removed. The recovery of the mangroves and vegetation since the
storm is evident in June of 2018.
Before and after hurricanes Irma and Maria.
6.09 RARE AND ENDANGERED SPECIES
All three rare or endangered sea turtle species; hawksbill turtles (Eretmochelys imbricata)
green turtles (Chelonia mydas) and leatherback turtles (Ermochelys coriacea) occur in
the area but neither of the docks or landing sites are turtle nesting beaches. NOAA's Sea
Turtle and Smalltooth Sawfish Construction Conditions will be followed as well as
NOAA's Vessel Strike Avoidance Measures and Reporting for Mariners in order to
protect these species. Acoustic impacts are also a potential impact to sea turtle species
therefore a vibratory hammer will be used during construction to minimize this impact
and if necessary pile will be socketed rather than impact driven. The use of an impact
hammer is not proposed.
The marine habitats around Great St. James have abundant coral and seagrass resources.
There are numerous ESA listed corals species near the proposed dock locations.
59
EFTA00802783
Acropora palmata, A. cerviconzis, Orbicella amzularis, O. franksi and 0. faveolata as
well as Dendrogyra cylindrus are found off all the cobble beaches from which the
proposed docks and barge landings are proposed. At the northern temporary barge
landing site, these corals are located primarily to the east where there are coral boulders
and coral rubble. There are few located on the shoreline cobble which extends out to a
depth of 6.5ft to 7ft. There are several small Acropora palmata and several Orbicella
ammlaris on the nearshore cobble and the presence of these species as well as several
Porites astreoides dictated the location of the barge landing. The proposed temporary
barge landing position avoids all coral and the landing approach is over sparse seagrass.
The western dock location is off a cobble beach between to areas of emergent bedrock
and boulders. Acropora palmata occur on the emergent bedrock to the north as well as
on the cobble. Offshore the seafloor quickly gives way to exposed pavement and there is
a long linear depression right offshore. An old piling lies within this area. The fractured
pavement then extends to a depth of approximately 11.5ft offshore over the next 130ft.
The area has some widely-scattered boulders and patchy coral colonization. There are
scattered ESA corals including Orbicella and Dendrogyra. During the first survey, there
was a very large Acropora cervicornis immediately seaward of where the old piling lay
near shore. However, upon the next visit by the island it was noted that an old boat was
tied nearshore apparently attached to the old piling. During a dive several weeks later it
was noted that the boat was gone and the large A. cerviconzis had been badly broken.
The location of the ESA species has dictated the location of the dock. Approximately 75
corals will require relocation to minimize impact, but no listed corals will need
relocation.
The southern dock also extends from a cobble beach which gives was to rock pavement
and has emergent bedrock and boulders on either side of the beach. There are Acropora
to the east and farther to the south on the bedrock and boulders. There are Orbicella and
Dendrogyra within the embayment and their locations have dictated the location of the
dock. The dock avoids all ESA listed corals but will require the relocation of
approximately 75 corals.
The island is known to be habitat to the St. Thomas Tree Boa (Epicrates monensis granti)
that is a federally listed rare and endangered species. The boa as well as another species
of snake were seen during the field studies. There will be special corridors and
preservation areas set aside on the island for these species. The access ways to the
western and southern docks already exist, but access will need to be developed to the
temporary barge landing. Vegetation along this access will be cleared by hand to limit
impacts to the tree boas. A tree boa mitigation plan is found in Appendix D.
6.10 Air Quality
All of St. John and St. Thomas is designated Class II by the Environmental Protection
Agency in compliance with National Ambient Air Quality Standards. In Class II air
quality regions, the following air pollutants are regulated; open burning, visible air
60
EFTA00802784
contaminants, particulate matter emissions, volatile petroleum products, sulfur
compounds, and internal combustion engine exhaust (Virgin Islands Code Rules and
Regulations).
There will be a slight increase in air emissions during the use of heavy equipment for pile
socketing/vibra-hammering. Once the docks are complete air quality will be impacted by
the periodic vessel visitations. The dock will have a negligible impact on air quality.
7.00 IMPACTS ON THE HUMAN ENVIRONMENT
7.01 Land and Water Use Plans
The property is zoned R-1, Residential Low density. The proposed structures are intended
to provide access to the residence on the offshore cay.
7.02 Visual Impact
The structures are proposed for the privately held offshore cay. The docks are all low
profile and will have turtle friendly solar lighting for visibility at night. Due to the
location of the cay the dock structures will only be visible from boats and from Little St.
James.
7.03 Impact on Public Services
7.03a Water
There will be no water service to the docks or landing.
7.03b Sewage Treatment and Disposal
There will no sewage associated with the docks or landing.
7.03c Solid Waste Disposal
The construction of the docks will have minimal waste production. The wood and
decking which will be removed from the dock which will be demolished will be recycled
and reused on the island and the piles will be used in landscaping. The ramp for the
temporary barge landing will not be removed unless required by the agencies. Ramp
would not be used unless there were an emergency and the southern barge ramp was
unusable. If the barge ramp is removed the concrete would be broken up and buried in
the islands disposal site. It will have no impact on public waste disposal facilities.
7.03d Roads, Traffic and Parking
The docks and landing are associated with an offshore cay and therefore have no impact
on public roads, traffic or parking. The roads on GSJ are private and are not public
roadways. The construction of the barge ramp, the docks and their use will not affect
62
EFTA00802785
public roads. The island roadways are hard packed dirt roadways and most traffic on the
roadways are smaller gators, and golf carts to transport employees. Upland development
including the roadways and roadway stabilization is discussed in the Master Plan
application.
7.03e Electricity
The docks and landing will use turtle friendly solar lighting.
7.03f Schools
The construction of the 2 docks and landing will have no impact on schools.
7.03g Fire and Police Protection
The development of the access docks and landing will improve fire department and
police access to the cay in the case of an emergency.
7.03h Health
The construction of these features will not increase the use of the public health facilities.
The construction of these docks and the landing will make it easier for emergency health
transportation to and from the cay.
7.04 Social Impacts
The construction of the docks and barge landing are proposed for a private offshore cay
with the intention to provide access to the owner and his staff. These activities on the
privately held island will not affect the islands of St. Thomas or St. John.
The western dock has been located as far north in Christmas Cove as possible while
minimizing benthic impacts. The bay is heavily used because it is an excellent mooring
area and therefore it is also a suitable location for a dock. Vessels will only approach the
dock at low speeds. Signage will be placed on the dock noting that it is an active private
dock and to use caution if swimming or snorkeling near the dock. Most of the activity in
Christmas Cove occurs to the south. The owner access to the island and the public use of
the moorings should be able to co-exist.
7.05 Economic Impact
The private docks and landing are not revenue producing. The permitting of the
structures will result in the payment of submerge land fees by the applicant.
63
EFTA00802786
7.06 Impacts on Historical and Archeological Resources
The proposed structures are in the shallow waters around Great St. James. Detailed
surveys were done as part of the benthic assessment. An old dislodged pile was noted
near the shoreline and one further offshore. These are being avoided due to coral
colonization. A request for a clearance letter has been sent to SHPO. A MOU is in place
for the upland portions of the island.
7.07 Recreational Use
People typically do not visit either the northern beach area or the southeastern dock site.
The Christmas Cove is however periodically visited by boaters and visitors who picnic on
the beach or walk on the shoreline. The docks will not interfere with public access to the
shoreline and the public will continue to enjoy free egress within the 50' set back.
7.08 Waste Disposal
The dock will not create solid waste, any trash from vessels will be disposed of in
receptacles on the island and hauled off with the other trash. The temporary barge
landing and access dock/barge land will facilitate the removal of trash form the island.
7.09 Accidental Spills
No fueling or repair will be allowed at the docks. The docks and landing will keep
emergency spill kits nearby so that in the event of an inadvertent release from a vessel it
can be quickly contained.
7.10 Potential Adverse Effects Which Cannot Be Avoided
The project will result in the alteration of an offshore cay and development on shorelines
which have previously been undeveloped. There will be water quality impacts due to
pile installation, but if the turbidity control and monitoring is implemented as proposed
impacts should be minimized and short term. There are corals within the footprints and
impact area of the construction and these will be transplanted prior to construction
(Mitigation Plan Appendix B). The docks have been designed so that the vessels are in
deeper areas and bottom disturbance should be minimized.
Christmas Cove is already heavily utilized by boat traffic, so the additional vessel use
should be negligible. Neither the northern barge landing or southern site are typically
used by boaters and this will result in increased boat traffic to both.
8.00 Mitigation Plans
To abate and minimize environmental impacts the following mitigation and monitoring
plans are proposed.
64
EFTA00802787
Coral Relocation and Mitigation Plan Appendix B
Water Quality Monitoring Plan Appendix C
Tree Boa Protection Plan Appendix D
The applicant will ensure that 20 white mangrove saplings (Laguncularia racemosa)
have become established in the southern wetland. A report will be filed with US Army
Corps of Engineers showing the survival of these trees in 2019.
9.00 Alternatives to Proposed Action
A siting study was done around the entire island. All potentially usable docking sites
were investigated. Site accessibility was one of the most restrictive issues.
The existing dock which is in Shallow Bay is far too shallow and its use has result in
damage to the once dense Thalassia testudinum beds within the bay. Although barges
have been landed in the bay it has resulted in damage to the shallow seagrass beds. The
bay is only 4ft deep 600ft off shore.
The dock in its current configuration is not approved by the USACE and the USACE has
requested its removal. It was not permitted due to the shallowness of the bay and the
potential impacts to the shallow seagrass beds. Shallow Bay is also not suitable for barge
landing.
In order to provide boat access and barge access to the island a new structure or structures
are necessary.
Many of the shorelines are inaccessible due to steepness. The most southern embayment
could support a dock with similar impacts as the selected sites, access to this embayment
was extremely difficult and would require significant cutting and filling which would
result in increased environmental impact.
On Christmas Cove there are several areas where a dock could be extended from the
shoreline with similar potential impacts as the proposed dock, however, the areas further
to the south would have greater seagrass impact, could impact the salt pond and would
have a significant impact on the public use of Christmas Cove since the dock would
extend into the highly used mooring area. The area selected in Christmas Cove is at the
far end of the cove and therefore will not result in boat traffic through the mooring field.

10.00 Relationship Between Short Term and Long Term Uses of Man's Environment
The existing access to the island of Great St. James is not suitable for the owners
intended residential use. The existing dock is in too shallow of a bay and is not federally
permitted in its current configuration. The development of a more suitable dock and
barge landing is in the best interest of the environment to abate impacts which are
occurring due to the shallowness of the bay which is now being used. The development
of adequate facilities for island access and the continuing requirements for the removal of
trash and delivery of supplies is in the best long-term interest for man's environment.

fundamental objective of compensatory mitigation is to offset environmental losses
resulting from unavoidable impacts to the waters of the United States authorized by DA
permits.
EFTA00802815
I. INTRODUCTION
Great St. Jim, LLC is seeking to construct two docks, one of which is a combination
dock/ barge landing, and a temporary barge landing to provide access to Great St. James
Island.
There is currently a small pile-supported dock located within Shallow Bay on the north
side of the island. The bay is very shallow and vessels accessing the dock have damaged
the shallow seagrass beds within the bay. At one time, there had been a concrete
bulkhead at the shoreline with a small floating dock. The previous owner submitted an
application for the existing dock which was approved by DPNR's Division of Coastal
Zone Management, but was not approved by the U.S. Army Corps of Engineers due to
objections by National Marine Fisheries because of the shallowness of the bay. The dock
was constructed by the previous owner despite not receiving the federal permit and
notices were issued by the USACE requesting the removal of the unpermitted structure.
The dock however was never removed. The applicant, understands the issues with the
existing dock and is proposing to remove the dock as soon as another dock is constructed
and usable.
A detailed study was done around the entire island to determine suitable locations for
dock location. All ESA listed corals were located and docks and barge landings were
designed to avoid these corals.
A temporary barge landing is being proposed on the northwestern facing beach. This site
is to the west of the salt pond and the associated wetlands. This a shoreline ramp which is
25 feet (ft) wide and 40ft in length extends to the Mean Water Line. The landing is free
of both coral and seagrass colonization. The landing is excellent for short term transfer of
material or equipment. The site is well protected from normal wave action but is
periodically impacted by wave action from ferries which travel through current cut
between Great St. James and St. Thomas. The wakes from these vessels make it an
unattractive site for mooring a barge for any length of time at the site. This landing can be
quickly constructed and utilized while the combination dock and barge landing on the
southeastern side of the island is constructed.
The western dock is proposed on the northern end of Christmas Cove. Historically there
was a dock in this location and there are still old concrete piles lying in the shallows of
this site. The proposed dock will be 10ft in width and 195ft in length extending 187ft
from mean low water (MLW) and I93ft from mean high water (MHW). The dock
extends beyond the nearshore hardbottom to a depth of 15ft out in the uncolonized sand
to allow for safe dockage for deeper vessels.
EFTA00802816
The southern dock is located off the point closest to Little St. James. The dock is "L"
shaped and is 20ft wide (to allow for barge landing) and 150ft in length extending 141ft
from MLW and 148ft from MHW, the "L" then turns east and extends 100ft by 20ft. A
wave attenuating/reef creating system is proposed beneath the dock which will allow for
more protected docking inside the dock when seas from the south are rough. The dock
has 9ft of water depth of the southern end and 7ft to 8ft on the inside of the "L". The
dock has been designed so that barges can approach and land on the end of the dock
while vessels can dock along the "L".
REASON FOR MITIGATION
The marine habitats around Great St. James have abundant coral and seagrass resources.
There are numerous ESA listed corals species near the proposed dock locations.
Acropora palmata, Acropora. cervicornis, Orbicella annularis, Orbicella franksi and
Orbicella faveolata as well as Dendrogyra cylindrus are found off all the beach from
which the proposed docks and barge landings are planned. At the northern temporary
barge landing site, these corals are located primarily to the west in an area of coral
boulders and coral rubble. However, there are several small A. palmata and several 0.
amiularis located on the shoreline cobble which extends out to a depth of 6.5ft. The
presence of these species as well as several non-ESA listed Porites astreoides has
dictated the location of the ramp. The proposed temporary barge landing position avoids
all coral and seagrass resources.
Location of the western dock has a cobble beach between two areas of emergent bedrock
and boulders. A. palmata occur on the emergent bedrock to the north. Offshore the
seafloor quickly gives way to exposed pavement. There is a long linear depression right
offshore and an old piling lies within this area. The fractured pavement then extends to
approximately 11.5ft of depth over the next 100ft heading offshore. The area has some
widely-scattered boulders and patchy coral colonization. There are scattered ESA corals
including Orbicella and Dendrogyra. During the first survey, there was a very large A.
palrnata colony immediately seaward of where the old piling lay near shore. However,
upon the next visit by the island it was noted that an old boat was tied nearshore
apparently attached to the old piling. During a dive, several weeks later it was noted that
the boat was gone and the large A. cervicornis had been badly broken. The location of all
the ESA species has dictated the location of the dock. Approximately 75 corals will
require relocation to minimize impact but no listed corals will need relocation.
The southern dock also extends from a cobble beach which gives way to rock pavement
and has emergent bedrock and boulders on either side of the beach. There are Acropora
colonies to the east and farther to the south on the bedrock and boulders. There are
Orbicella and Dendrogyra within the embayment and their locations have dictated the
location of the dock. The dock avoids all ESA listed corals but will require the relocation
of approximately 75 corals.
EFTA00802817
II. MITIGATION OBJECTIVES
It is the objective of this mitigation project to limit the amount of coral and coral habitat
that is lost as a result of the dock and barge access construction. All of the coral, sponge,
and sessile life forms within the footprint of the facility or which might be potentially
impacted during construction or operation will be transplanted. Approximately one
hundred and fifty (150) corals will be relocated.
III. SITE SELECTION
The recipient sites were selected due to their being similar environments and being close
to the mitigation site.
The corals from the Christmas Cove site will be located to the north onto the adjacent
hardbottom areas which are at equivalent depths. The corals from the southeastern dock
site will be transplanted to the hardbottoms to the south which are at equivalent depths.
IV. SITE PROTECTION INSTRUMENT
The applicant will prepare an easement setting these areas aside as protected areas.
V. BASELINE INFORMATION
Benthic Habitat Description
General
Sandy beaches, cobble beaches and steep rocky shorelines surround great St. James
Island. All three of the proposed dock and barge landing sites will extend from cobble
beaches. The northern shore where the temporary barge landing is proposed has cobble
which extends down to a depth of approximately 7ft and has sparse seagrass colonization
within the barge approach. There are scattered corals in the bay to the east and dense
seagrasses offshore beyond the landing site. The cobble within the landing site is only
colonized by fire coral. The emergent bed rock to both the east and west sides of the bay
are colonized by corals species including ESA corals.
The northern portion of Christmas Cove where the Access Dock is located has emergent
bedrock to either side of the small embayment which are colonized by coral and sponge
species. Rock pavement and scattered boulders extends offshore to a depth of I I.5ft
where it gives way to a sandy bottom. Corals and sponges colonize the rock pavement
and scattered boulders. There is seagrass off shore but it begins beyond the terminus of
the proposed dock.
The southern facing dock is off a cobble beach between to rocky shorelines. There is
rock pavement extending off shore and then broken rock pavement further out. Corals
and sponges colonized the rock pavement.
EFTA00802818
ESA listed coral species are found at all three locations and the Nassau Grouper
(Epinephelus striatus) was seen off both the Christmas Cove and southern dock site.
Methods
The NOS St. John and St. Thomas Habitat map Tile 16 (Figure 6.06.1) of the Great St.
James area shows the colonized rock pavement and bedrock as well as the offshore
seagrass beds. The seagrass beds are not as continuous near the shoreline as shown, and
the offshore area at both Christmas Cove and the southern dock site are colonized
pavement rather than bedrock right off the cobble beaches and on the northern facing
beach the pavement doesn't extend completely across the bay as shown. Surveys were
done on Scuba and Acropora palmata and Acropora cerviconds, Dendrogyra cylindrus,
Orbicella annularis, Orbicella faveolata, Orbicella franksi, and Mycetophyllia ferox were
mapped so that they could be avoided. Habitat boundaries were marked with GPS and/or
by the surveyor for accuracy. Percent abundance was determined along transect lines and
utilizing a meter square.

Benthic Resources
Great St. James is located off Water Point on the eastern end of St. Thomas. This oddly
shaped island has a variety of shoreline types and six salt pond/wetland habitats. There is
a well-protected shallow northern bay where an existing dock is located. Shallow Bay is
colonized by seagrass which includes Thalassia testudinum, Syringodium Monne and
Halodule wrightii. Recently the sea vine Halophila stipulacea has colonized areas which
have been disturbed. The densest seagrass beds once lay near shore and to the east of the
dock. Over the last several years these beds have been highly disturbed. The peninsula to
the east of this point is surrounded by rocky headlands and is a very exposed
EFTA00802819
environment. The rocky cliffs extend below the sea surface and due to the intense wave
action, the shallowest areas are not colonized. By a depth of 8ft-10ft the rocky substrate
becomes colonized by a wide variety of corals and sponges. The slope is steep offshore
and the water reaches a depth of 40ft to 50ft relatively close to shore. The rocky slope
gives way to a cobble then sand bottom and there are sparse to moderately dense seagrass
beds that extend seaward. The rocky shoreline continues around to the south, with coral
colonized nearshore hardbottom and seagrass colonized sand and cobble further offshore.
There are two cobble beaches further to the south divided by a small rocky headland,
there is some colonized beach rock nearshore and shallow seagrass beds off shore. The
shoreline facing St. James Cut and the southern end of the island is rocky. This area has
limited coral colonization in the inner tidal zone giving way to an abundant diverse coral
community on the submerged rocky slopes. The rock is relatively steep with numerous
grottos, and caves, and gives way to a cobble/sand bottom at around 20ft to 25ft. There
are moderate to dense seagrass beds off shore. The Stragglers lay off the southern most
point of the cay, and like the southern shoreline of the island there is minimal
colonization in the inner tidal areas of the emergent rocks with coral colonization and
diversity increasing with depth. The western shoreline is well protected and is a
combination of rock and sandy beach. The water deepens much more gradually on this
side of the island. In the areas with rock along the shoreline are colonized by corals and
sponges. The less colonized inner tidal area is much less defined here due to the more
protected nature of the site. Within Christmas Cove there is a rock groin like structure
that extends into the bay near the center of the embayment. Offshore to the north of the
groin there is a small beach rock shelf and then a strip of uncolonized sand before sparse
to moderately dense seagrass beds begin. The site is currently used by boats anchoring
adjacent to the beach.
To the south of the groin there is a beach rock shelf with moderate coral colonization
which falls off to depth of over 6ft only 40ft from shore and there is a board area of
uncolonized sand out to a depth of 10ft before reaching the moderately dense seagrass
beds and open sandy plains. The shoreline becomes rocky again to the north along
Current Cut and the area is more subject to wave and current action. There is coral
colonization along the rocky shoreline and on the rock pavement that extends off shore.
The north-facing bay to the east of Current Cut is a mixture of cobble and rocky shoreline
with a small sandy beach in front of the salt pond. Where rock is present there is coral
colonization and in the open sandy areas there is moderate to dense seagrass colonization.
The temporary barge landing is located at the western end of the north-west bay. The
landing. The beach is cobble and the cobbles extend out to a depth of 7ft at the landing
site. The landing site contains some scattered Millepora complanata, but no hard-coral
species. There are scattered corals to the east in the cobble including a few Orbicella
amudaris and Acropora palmata. Porites astreoides is the most abundant coral in the
cobble to the east. The location for the barge ramp was chosen due to the presence of
corals and coral colonized boulders throughout the bay to the east. To the east in the bay
there are numerous Orbicella annularis, O. faveolata and Dendrogyra cylindrus as well
as other coral species. Offshore there are dense seagrass beds consisting of 77wlassia
testudinum and Syringodiumfiliforme, however these are greater than the 75ft off shore
EFTA00802820
which the barge will extend while moored. There very sparse Syringodium colonization
within the barge approach, representing less than 5% bottom coverage.

The access dock in Christmas Cove is near the location of an old historic dock. The beach
is a mixture of sand and cobble. There is rock pavement extending offshore and there is
an area of cobbles in the center of this area which is uncolonized out to a depth of 5ft.
The rock pavement has various depressions and breaks and within one of these
depression is a pile from the old concrete dock. Beyond the depression, the water deepens
quickly out to a depth of 12ft. The rock pavement is colonized by Diplona strigosa, D.
labyrinthifonnis, Orbicella annularis, 0. franksi, Porites astreoides, P. porites,
Dendrogyra cylindrus, Gorgonia sp. and Millepora sp. and the sponges Aplysinafidva,
Amphimedon compressa and Ircinia sp. Coral colonization increases on either end of the
small embayment and with depth. Beyond the nearshore hard bottom, approximately
120ft off shore the bottom becomes sandy. There is a minimally colonized area before the
bottom begins to become colonized by Syringodiztmfilifonne which slowly grades into a
mixed bed of Thalassia testitudium and Syringodium. The exotic seavine Halophila
stipulacea is also present. This seavine was not present in 2006.
There was a very large intact Acropora cerviconzis in the center of the bay just off the old
dock piling in the depression early in 2016. However, a boat moored on the old piling
and on a subsequent dive the Acropora was found completely broken. Pieces of this
Acropora remain. There are Acropora palmata in the shallows to the north of the
proposed dock location both on the cobble and bedrock.

The Access Docic/Barge dock is located in the bay closest to Little St. James. Like the
other two bays there is cobble on the shoreline which extends into the sea to 2ft to 4ft of
water depth. Offshore there is pavement with boulders and odd rock formation. The area
is colonized by scattered corals which are most abundant on the boulders. Orbicella
annulans, O. franksi, O. faveolata, Dendrogyra cylindrus, Porites astreoides, P. porites,
Diplona strigosa, D. clivosa. D labyrinthifonnis Gorgonia sp. and Millepora sp. and
sponges Aplysinafidva, Amphimedon compressa and Ircinia sp. are present. Acropora
palrnata is present on the headlands to the east and south.
There are scattered boulders and broken pieces of bedrock offshore, most of which are
colonized by corals and sponge species.

VII. MITIGATION WORK PLAN
CORALS
Prior to the start of the relocation project the footprint of the docks and the predicted
impact zone will be marked on the seafloor using small pin flags. Any coral or boulder
which partially extends into this zone will be relocated.
Individual corals that are attached to the near shore hardbottom will be removed with
chisels. These corals will be collected in bins and carried to recipient site. These corals
will be fixed in placed in their new locations with two-part underwater epoxy, which sets
in a matter of minutes (Splashzone). The base of the coral will be carefully cleaned with
a wire brush and the new substrate will be cleaned to remove algae and any other material
which might interfere with the adhesion of the epoxy or cement. The coral will be
carefully placed and held until the epoxy starts to set.
Divers will then collect those corals and sessile invertebrates that colonize cobbles and
rocks within the dock footprint that are of a small enough size to allow hand carrying.
These are cobbles and boulders that are in a range of I ft2 to 2.5ft2. These corals are
usually growing on pieces of coral rubble. Divers will wear disposable gloves while
working with corals minimize touching live tissue and keep any coral that appear
unhealthy or diseased away from other corals. Corals which appear to be diseased will be
marked, and not transplanted to the recipient area to minimize the potential of the spread
of disease to the recipient site. The diseased corals will be photographed and will be
addressed in the baseline report for the transplant identifying the size and location of each
individual colony. If a coral is handled that appears unhealthy or diseased gloves will be
changed prior to working with other corals. The I ft2 to 1.5112 corals will be placed in
underwater bins and carried by divers to the recipient sites. The larger corals will be
placed directly on a transport tray. Once the tray is full it will be lifted by lift bags and
walked to the relocation site. Once on site the tray will be lowered near the seafloor and
divers will remove the corals from the tray. The coral will be placed in the recipient site
in such a fashion that the rock is stable and will not be subject to movement. This will be
done by digging a depression in the sand to rebury the base to the same depth as it was
prior to transplant. Care will be taken to make sure no live tissue is buried or too close to
the sand that it may become buried. If possible if hard substrate or other larger rocks or
rubble is found the coral base will be attached to it with "Splashzone" two-part
underwater epoxy. Care will be taken so that these transplanted materials will not impact
existing organisms at the transplant site.
Splashzone epoxy is used because it is approved for drinking water systems by EPA.
This epoxy does not leach any harmful chemicals into the water. This epoxy also does
not create the temperature change which occurs with hydraulic cement.
For corals and larger coral colonized rocks, those greater than 2.5ft2, lift bags, and ropes
will be utilized. divers will lift and transport larger corals, and coral colonized rocks then
slowly carry the organisms to the transport tray. Again when the tray is full it will be
EFTA00802826
lifted and walked to the recipient site. When attaching the corals to the lift bags ropes
will be placed so that they avoid live coral tissue. If necessary, a plate may be placed
underneath corals so that it lifted without the tissue being impacted by the ropes. The
coral boulders and larger rocks will be placed in the recipient site in such a fashion that
the rock is stable which may require some excavation into the sand to create a depression
for the previously buried part of the rock. Care will be taken so that these transplanted
materials will not impact existing organisms at the recipient site. Care will be taken to
place corals in the same orientation and depth as they were in their original locations.
COMPENSATORY MITIGATION
To mitigate for impacts that cannot be avoided a special reef building system will be
placed beneath the southeastern dock. This system serves not only as a wave attenuator
by provides additional substrate to allow for colonization beneath the dock. Grated
decking will be used on the dock to facilitate light transmission.

VIII. MAINTENACE PLAN
Divers will survey the recipient site on a bi-weekly basis for the first 2 months after the
transplant to ensure that the corals have not become unattached or shifted. If for any
reason the corals become loose or move they will be re-situated and or reattached. After
the first two months the corals will be monitored on a monthly basis for the first year and
then on a bi-monthly basis for the following 2 years then every 6 months for year 4 and 5
after the transplant. During each monitoring event divers will make sure that the rocks
have remained stable and not shifted, and that corals and sponges have not come loose.
If necessary corals will be repositioned and re-attached.
IX. ECOLOGICAL PEFORMANCE STANDARDS
The object of this mitigation is to minimize impact to benthic resources which provide
high quality habitat to marine species. In order to objectively evaluate the mitigation
project, ecological performance standards must be established. The performance
standards will include viability of the transplanted corals and sponges and relocated
seagrass.
It is the intent of this transplanting program to obtain a minimum of 80% survival of the
transplanted corals and sponges. Great St. Jim, LLC is committed to put forth the
greatest effort to see that the relocation is successful and that they obtain the greatest
potential survival of transplanted organisms.
X. MONITORING REQUIREMENTS
Monitoring the compensatory mitigation project site is necessary to determine if the
project is meeting its performance standards, and to determine if adaptive measures are
necessary to ensure that the project does meet its objectives.
As per the guidelines set forth in §230.96 Monitoring the mitigation project will be
monitored for a minimum period of 5 years.
In total twenty-five transplanted corals at each site will be marked with numbered tags for
monitoring. The tags will be maintained throughout the 5 year monitoring period. The
corals will be surveyed for percent live tissue, color, algal growth and indicators of
disease and photographed on a monthly basis for the first twelve (12) months. Corals
will then be monitored on a bi-monthly basis for the follow 2 years and then every 6
months for years 4 and 5 after the transplant. The percent live tissue, color, stress,
surround algal growth, algal growth on dead areas of tissue and any signs of disease for
each monitored coral will be noted in the reports.
If at any time during the monitoring degradation of the corals is noted, degradation being
defined as tissue loss, indication of disease, color change, excessive algal growth or
notable mucus, affected corals will be compared to those within the other monitoring
quadrats and corals in areas outside the impact area of the project. This information will
be used to determine whether the degradation of the corals is due to the transplant,
EFTA00802828
activities related to construction or resort or due to natural phenomena (such as wide
spread bleaching). If the corals appear to be stress due to the transplant, the reason for
the demise will be assessed, poor positioning, sand scour, light attenuation, etc. If
necessary, the coral or sponge will be repositioned. Every effort will be made to save the
coral or sponge. If the degradation is seen both in the project area non-transplanted
corals and the transplanted corals, the reason will be assessed for the demise. If the
source of the impact cannot be readily assessed by the monitoring being undertaken, the
monitor will work with NMFS and VI Fish and Wildlife and the other resource agencies
to expand the monitoring so that the source of the impact can be identified.
In order to monitor the success of the reef creating system under the southeastern dock, it
will be monitored concurrently with the corals and a detailed photographic recorded will
be kept depicting colonization, survival and growth of coral and sponge species.
The monitoring results will be delivered to the agencies within two weeks of the
monitoring period. If negative impacts are noted the agency will be notified by phone
and by email within 24 hours. The agencies will be apprised of what steps are being
taken to identify the impact and rectify the problem. The agencies will be provided a
detailed report on the steps that are taken and the results of those actions.
XI. LONG TERM MANAGEMENT PLAN
Great St. Jim, LLC is committed to the survival of the transplanted coral species and the
success of the reef building system and will make every effort to ensure that both are a
success.
XII. ADAPTIVE MANAGEMENT PLAN
In the event that there are difficulties with the mitigation or if the mitigation is deemed
unsuccessful as planned, Great St. Jim, LLC is prepared to take additional steps to see
that compensatory mitigation goal is achieved. If necessary, extended monitoring and
maintenance or additional marking of the sites will be undertaken in order to meet the
mitigation goal.
If the mitigation goal of 80% survival at the end of five years is not met, the applicant
will prepare a detailed report of why the mitigation was not successful. Great St. Jim,
LLC will meet with the permitting agencies to determine the additional compensatory
mitigation needed to meet the mitigation goal.
XIII. FINANCIAL ASSURANCES
Great St. Jim, LLC will secure a performance bond in the amount of the cost mitigation
program and subsequent monitoring throughout the implementation and monitoring
period or provide another form of acceptable financial assurance. The bond will follow
the guidelines set out by the U.S. Army Corps of Engineers Regulatory Guidance Letter
EFTA00802829
No. 50-1, 14 February 2005, SUBJECT: Guidance on the Use of Financial Assurances,
and Suggested Language for Special Conditions for Department of the Army Permits

ENVIRONMENTAL AND WATER QUALITY MONITORING PLAN
FOR THE
CONSTRUCTION OF A TEMPORARY BARGE LANDING
AND TWO DOCKS ON
GREAT ST. JAMES, U.S. VIRGIN ISLANDS
INTRODUCTION
The following is the proposed monitoring program for the construction of a temporary
barge ramp and two docks on the island of Little St. James. The purpose of this
monitoring plan is to evaluate and minimize the impact of the proposed construction on
marine water quality and the benthic community.
Great St. Jim, LLC is seeking to construct two docks, one of which is a combination
dock/ barge landing, and a temporary barge landing to provide access to Great St. James
Island.
The marine construction will consist of the vibra-hamming or socketingof piles and the
placement of docks. The impact pile driving or vibra-hammer driving will have a
minimal potential for creating turbidity. However, where rock encountered it is possible
that piles may need to be socketed. Pile socketing greatly increases the potential for
turbidity, and creates large volumes of rock flour. Based on observations in the field a
number of piles may require socketing.
Turbidity barriers (silt curtains) will be installed surrounding all pile driving/socketing
activities. The curtains will serve not only to maintain turbidity created by pile driving
but will also contain floating debris within the project area. The turbidity barriers will be
properly installed and will extend to within 1 ft. of the seafloor where piles are driven. If
piles require socketing, curtains will extend to the seafloor and a double set will be
deployed.
ESTABLISHMENT OF BASELINE CONDITIONS AND SAMPLING POINTS
Prior to the start of any construction activities a baseline of existing conditions will be
assessed. Baseline samples will be conducted over a two-month period. The sampling
locations have been established to encompass the area most likely to be potentially
impacted during construction. The baseline samples sites are shown in Figures 1 and 2.
No monitoring should be necessary for the temporary barge landing. Baseline samples
will be tested for secchi depth and turbidity expressed as NTU. As part of the baseline
sampling, sampling during normal and storm conditions will be completed prior to
project construction to determine the natural range in turbidity and duration of elevated
turbidity levels to which corals in the area are naturally exposed. Samples will also be
taken after large rainfall events which result in an influx of runoff to determine the
existing sediment runoff.
EFTA00802831
DURING CONSTRUCTION
MARINE WATER QUALITY MONITORING
During the construction of the docks water quality at the stations in the vicinity of the
work will be sampled on a daily basis. Three water samples will be taken 10 meters
outside the turbidity barriers surrounding the area of work. Two control samples shown
in Figures 1 and 2 will also be sampled. Water quality will be secchi depth and turbidity
expressed as NTUs.
ACTION TRIGGERS
During construction if the water samples show NTUs, or secchi disk readings outside the
allowable regulatory limits, the reviewing agencies and the applicant will be notified, in
writing within 24 hours of the parameter exceedance. The baseline samples will be
utilized to determine if other parameters are elevated above normal background levels.
Controls will also be used to determine if the readings are a result of natural phenomena
or if the monitoring sample is elevated above the ambient background as a result of the
construction project.
If it is determined that the elevated turbidity is the result of the construction project, the
source of the elevated turbidity will be identified and methods worked out to abate the
degradation. Someone will be on hand at the construction site at all times who has the
authority to implement sediment control devices or other remedial actions, so that
problems can be resolved as quickly as possible. Once the source of the impact is
identified, steps will be taken immediately to abate that impact. The action that was taken
to resolve the issue, as well as confirmatory sampling data that the degradation has been
resolved will be included within the written report to the agencies and GSJ. A monitor
will be on site throughout the day during construction activities to ensure that turbidity
barriers are adequate maintain and that escaping sediments do not go unabated.
REPORTING OF DATA
In the event of any emergency or noted degradation in any of the water quality
parameters above the allowable or acceptable limits, or any impact to the benthic
community the owner and the reviewing agencies will be immediately notified in writing
by e-mail. NMFS will be notified immediately of any impact to ESA listed species.
Weekly water quality reports will be delivered to all agencies and GSJ throughout the
monitoring period.

VIRGIN ISLANDS TREE BOA MITIGATION PLAN — GREAT ST. JAMES ISLAND
ACCESS DOCK CONSTRUCTION
Introduction
Little St. James island habitat for the Virgin Islands Tree Boa, Epicrates monensis granti and two tree
boas were seen in 2006 on the island. The tree boa was listed as Federally Endangered in 1979 and the
Virgin Islands Endangered and Indigenous Species Act also protects this species. The tree boa is
nocturnal and arboreal, the snake forages at night and seeks shelter during the day. The snakes seek
refuge in termite nests, debris piles and under rocks during the day. While the snakes' habitat is listed
as dry forests, coastal scrub, moist woodlands, mangroves and rocky cliffs, the snakes can occur in any
habitat that allows for off ground movement. The structure of the habitat is more important than the
species composition; the dock access had some structure which might be adequate for these species.
There is an abundant prey base of lizards on the cay, and there is refugia present; logs and rock piles.
Fish and Wildlife states that the snakes are extremely difficult to locate even for an experienced snake
biologist, and therefore it must be assumed that the endangered species is present, especially when
suitable habitat and refugia are present. Tree boas are known to be present the applicant will make
every effort not to take (harass, harm, pursue, shoot, wound, kill, trap, capture, or to attempt to engage
in such conduct) any of these endangered species. The dock access way will be cleared by hand and
rock piles will be dismantle by hand. All personnel involved in site clearing and site construction will be
informed of the potential presence of the snake, and the importance of protecting the snakes.
Photographs of the tree boas will be shown to all workers as well as a description of their behavior and
habitat. All workers must acknowledge that they understand the importance of protecting this rare and
endangered species. The site will be cleared directionally from the existing access way towards the
shoreline. If tree boas are encountered, work will be stopped in the area of the snake, and the Division
of Fish and Wildlife will be contacted immediately. Ever means necessary will be implemented to
prevent harm to the tree boa.
The DFW will be notified of any snakes observed or capture. Phone numbers for Fish and Wildlife will be
posted at the site to aid in immediate notification.

ARTIFICIAL REEFS
"When Marine Ecosystems were first being developed, it was just another artificial reef. However, over
time they quickly expanded to areas that entail: wave attenuation, snorkeling reefs, oyster reef
restoration, mitigation, shoreline stabilization, personal dock reef, coral reef restoration and to be used
as a research tool.
Our EcoSystems are a culmination of 22 years worth of work in designing and deploying over 35,000
artificial reefs. Its complex (rugosity) design allows small marine animals to seek shelter and protection
from larger predators and is ideal for defusing wave energy above the water line. This allows you to
place an ecosystems in a high-wave energy area without worry about a storm event damage. The Florida
Limestone rock used replicates natural reef substrate and PH. The EcoSystems create an environment
for all marine life to attach and this does include boring animals which was something no other artificial
reef out there has been able to do. The pile mounted design, utilizing a Pearson Piling mount system,
guarantees the unit will stay upright and not sink into the bottom as well as provide proper flushing and
creature mobilization."
