PART 6: Describe in general teans the praposed project, system, or aciivity.
The proposed project would consist of a tiered sheet-pile system located west of the MHWL to stabiiize the severely
eroded banks of the Jupiter Inlet Lighthouse Outstanding Natural Area (JILONA) along Jupiter Sound. A"living
shoreIine" concept (Figure 1) would be utilized to restore the adjacent shoreline, creating approximately 0.31 acres of
O shallow water habitat for seagrass recruitment, 0.20 acres of mangrove habitat, 0.29 acres of high marsh habitat and 0.17
acres of submerged hardbottom habitat {Figure 2). The pmposed project includes approximately 1,4001inear feet of
emergent limestone breakwater designed to attenuate wave energy and create hardbottom habitat. Due to the bathymetry
along the shoreline at the south end of the proj ect, approximately 2500 c.y, of fill material, dredged as part of a future
ICW maintenance project, would be placed to support the southern breakwater segments and create shallow water habiiat
' for seagrass recruitment. The fill material wouid be held in place by a 560 ft submerged toe-wall. Figure 3 illustrates a
typical graphic cross-section at the south end of the project. Figures 4a-4c are time series simulations from a
perperidicular perspective of the proposed living shoreline concept. Pigures Sa-Sc are rime series simuladons of an
obiique view ]ooldng a3ong the proposed living shoreline concept.

Project Name JII.ONA Shoreline Stabilization and RestoratioQ Project
County Palm Beach
� Owner Bureaa of Land Management
Applicant: Bureau of Land Management
Applicant's Address: 411 Briarwood Drive; Suite 404, Jackson, MS 39206
1. Indicate the project boundaries on a USGS quadrangle map. Attach a location map showing the boundary of the
proposed activity. The map shoald also contain a north anow and a graphic scale; show Section(s), Township(s), and
Range(s); and must be of sufficient detail to allow a person unfamiliar with the site to find it.
USGS quadrangle map is available on Figure C-1. Prnject boundaries {X, Y coordinates) and proximity
to ICW setbacks are available on Figure C-6.
2. Provide the names of all wetlands, or other surface waters that would be dredged, filled, impounded, diverted,
drained, or would receive discharge {either directly or indirectly}, or would otherwise be impacted by the praposed
activity, and specify if they are in an Outstanding Florida Water or Aquatic Preserve:
Jupiter Sound within the Jensen Beach ta Jupiter Inlet Aquatic Preserve
3. Attach a depiction (plan and section views), which clearly shows the works or other facilities proposed to be
constructed. Use multiple sheets, if necessary. Use a scale sufficient to show the locaiaon and type of works.
� See Attached Permit Drawings — Figures Cl — C5.
The project shall tie into an adjacent shoreline stabiiization project currently permitted for the U.S. Co�st Guard
property immediately south of the project property. The ERP permit and proposed modification for the Coast
Guard project are included as Attachment C.
4. Briefly describe the proposed project (such as "construct docic with boat shelter", "replace two exisiing culverts",
"construct surface water management system to serve 150 acre residentiai deveiopment"):
The project proposes to stabilize the biuffs along the Jupiter Sound with a tiered sheet-pile system along 705 feet of
prnperty, Iocated west of the MHWL. A segmented emergent breakwater, designed to attenuate wave energy while
allowing safe manatee access, wilI be constructed to stabilize the shoreline along the ICW. Dne to the bathymetry
along the shoreline at the south end of the project, approximately 2504 c.y. of fill material, dredged as part of a
futare ICW maintenance project, will be placed to support the southern breakwater segments and create shallow
water habitat for seagrass recruitment. A 560 ft submerged toe-wall will be installed along the eastern boundary of
the fill template to isolate the �ill from the ICW.
5. Specify the acreage of wetlands or other surface waters, if any, that are proposed to be filled, excavated, or
otherwise disturbed or impacted by the proposed activity:
• filled 0.39 ac.; excavated ac.; other impacts 0.12 ac. {surface water lost to limestone structures)
b. Provide a brief statement describing any proposed mitigation for impacts to wetlands and other surface waters
(attach additional sheets if necessary}:
Impacts to submerged bottom will be offset by the creation of approximately: 0.29 acres of high marsh
habfitat, 0.20 acres of mangroves, 0.17 acres of subme�rged hatdbottom habitat and 0.31 acres of seagrass
recruitment area.

� SECTION E — PROJECT NAR1tATNE
Jupiter Inlet Lighthouse Outstanding Natural Area
Shoreline Stabilizatian and Restoration Project
Palm Beach Caunty, Florida
Project Purpose
The U.S. Deparlment of the Interior, Bureau of Land Management is seeking an Environmental
Resource Permit (ERP) to stabilizre and enhance the shoreline adjacent ta the Atlantic Intracoastal
Waterway (IC'UV�. The project site aand its adjacent property were congressionally designated as
- the Jupiter Inlet Lighthouse Outstanding Natural Area (JII.,ONA) on May 8, 2008. The
Consolidated Natural Resources Act of 2008 established legislative requirements that:
"The Secretary, in corasultation with the Local Partners and the Commandant, shall
manage the Outstanding Natural Area — as part of the National Landscape Conservation
System; in a manner that consen»es, protects, and enhances the unique and nationally
important historical, natural, cultural scientific, educational, scenic, and recreational
J values of the Outstanding Natural Rrea, zncluding an emphasis on the restoration of
native ecological systems. "
The project shoreline has been impacted by a variety of influences including; periodic dredging of
the ICW channel, wave action, tidal energ,y, storrn impac�s and unauthorized recreational use. As
a result, there has been significant bank erosion during the Iast 30 years and a shoreline retreat of
up to 100 feet over the Iast 50 years (Figure E-1).
The Bureau of Land Management proposes to stabilize the b�nk with a tiered sheet-wall system
and stabilize the shoreline with a segmented emergent breakwater to attenuate vwave and tidal
energy. The breakwater segments alung the most heavily impacted section of the shoreline will
be placed approxirnately 50' landward of the 1953 shoreline to facilitate crearion of shallow water
habitat for seagrass recruitment and establish a refuge for rnanatees that is isolated from the ICW
boat channel.
�J
� Project Location
The proposed project site consists of approximately 1,540 feet of shoreline adjacent to the ICW
just south of State Road 707 in northern PaIm Beach County, Florida within Section 31 Township
40S and Range 43 E. The project site is 0.5 miles west of the Jupiter Inlet and includes the west
bank of the Indian River.
Project Descripiaion
The proposed project will:
• Remove exotic vegeta.tion from tYie bank and shoreline
• Construct a 3 riered sheet wall system to stabilize approximately 705 linear feet of
the high banics
• Install 560 linear feet of subnnerged sheet pile in approximately 13' of water to
suppart the backfill and isoiate it from the TCW channel
• Utilize approximately 2500 c.y. fill from a future ICW maintenance dredging effort
to eleva.te the profile of the submerged shoreline landward of the submerged toe-
wall
C� • Construct an emergent segmented breakwater consisting of 8 limestone sh�uctures
with a cumulative exposed crest length of approximately 1,4001inear feet
• Fstablish high marsh and mangrove communities along the project shoreline
The proposed sheet wall system will consist of three tiers of vinyl sheet pile. The gaps between
each wall shall be bacl�'illed to match the elevation of the seaward wall and planted with native
herbaceous plants found in upland and scrub habitats.
A steel sheet pile is proposed offshore of the southern section of shoreline to facilitate the
placement of fill foz the lzving shoreline concept. The sheet pile toe wall shall remain submerged
at all times and shall isalate the fiIl material from the ICW channel. It is anticipated the dredging
frequency of the adjacent ICW channel will be reduced by stabilizing the sediment of the bluff
and shoreline.
1'he breakwaters shall be consfizcted using limestone boulders approximately 2 feet in diameter
with a minimum density of 140 lbs/cu. #'oot. The five northern stxuctures shall be placed along
the mean low water elevation and shall be'landwazd of the documented seagrass bed. The three
i� southem structures shall be placed on fill used to elevate the profile to approximately -4.0 NAVD
88. Consultation with the US Coast Guard an the proposed breakwaters with respect to navigation
�� was initiated on Apri126, 201 i. All eonditions or concurrence shall be pro�vided to the permitting
� agencies when available_
Table 1 provides the required Seetion E project impact summary. Since no permanent irnpacts
are anticipated to any natural resources, no mitigation is proposed in Tables 2 and 3. No docldng
- facilities are included with this proiect as indicated on Table 4. Table 5 pravides the required
shoreiine sta.bilization information.
Land Ownership aud Sovereign Submerged Lands
On May 8, 2008, Congress passed the Consolidated Natural Resources Act (PL-110-229)
creating the 124-acre Jupiter InIet Lighthouse Outstanding Natural Area. The legal description of
the property is:
Tallahassee Meridian
Township 40 South, Range 43 East, Sectian 3I
i � � Including those portions of Lots 15, 16, 17, 18, 19 and 20
� within the Outstanding Natural Area baundary
The responsible contral of the ONA is divided among three entities; Lots i5, 17 and i9 with the
Burea.0 of Land Management, Lots 16,and 18 with the U.S. Coast Guard and Lot 20 �with the
Town of Jnpiter (Figure E-2}. On May 2, 201 l, withdrawal revocation was published in the
Federal Register transferring administrative jurisdictian of Lot 17 from the U.S. Coast Guard to
the Bureau of Land Management. The Consolidated Natural Resources Act of 2008 states any
lands returned to Bureau of Land Management from the U.S. Coast Guard will be managed as
� part of the Jupiter Inlet Lighthouse Outstanding Natural Area.
Attachment C provides a list of adjacent property owners. If necessary, the Bureau of Land
Management is prepared to send public notices to these adjacent property owners. However,
noticing shall be held until a consensus with the State is achieved regarding the total scope of the
projec�k
;�
�
�� �n January 2010, the Division of State Lands deternuned the submerged lands lying belaw the
rnean high water line are State owned and lie within the Jensen Beach to Jupiter Inlet Aqualic
Preserve (Attachment D). .
In accordance with Rule 18-21.011(7), the Bureau of Land Management requests a waiver from
payment a� annual lease fees. The proposed project represents a not-for-profit government
endeavor that is not intended to generate revenue.
Sheet Pile
The proposed sheet wall system will consist of three tiers of vinyl sheet pile that have 5 feet of
exposure above grade. The system will begin at +2.0 NAVD 88 and terminate at an elevation of
f17.0 NAVD 88. The gaps between each wall, 4 feet in width, shall be backfilled to match the
elevation of the seaward wall a.rzd planted wiih native herbaceons plants found in upland and
scrub habitats.
;--� Steel sheet pile shall be insta.11ed affshore at approximately -13.0 NAVD 88 and shall remain
� submerged at all times with a top elevation of -4.5 NAVD 88. The north corner of the submerged
sheet pile lies within the ICW Right of Way, but is outside of the 62.5 foot setback required by
the Florida Inland Navigation District (FIND).
Fill
The project proposes using fill to elevate the existing bathymetry to create a perched shoreline
that will facilitate a living shoreline design with shallow water habitat. It is the intent of the
applicant to utilize material that would be dredged from the ICW during future FIND
maintenance dredging of the ICW channel (Pezxnuit No. JCP 0262913-001-JC) oz 7ID dredging of
the sand trap {Permit No. JCP 0134395-001-JC). To achieve the necessary eleva.tion for the
shallow water habitat, approximately 2500 c.y. of materiai wonld be required. The existing
elevations of -13.0 NAVD 88 at the wate�r-ward edge would be filled to an elevation of -5.0
NAVD 88 and retained by the steel sheet pile toe wall.
During fill o}serations, turbidity control devices, (i.e., turbidity curtains and silt fences) placed at
�� �
appropriate locations during active construction, wili prevent water quality degradation within the
� work area. ln addition, best management practices (i.e., turbidity monitoring), employed du�ring
t ^� constr�uction, will minimize impacts ta the surrounding waters. Tvrbidity monitoring will include
sampling after the first hour of filling and every four hovrs thereafter during filling operations or
any other construction activity that may result in a water quality violation. The applicant vv�ill
collect water quality samples for turbidity analysis at mid-depth from the following stations:
1. Background Sample — The applicant will sample approxixnately 100 feet up-current
of the work site and clearly outside the influence of cons�uction activities. This sample
wi11 provide the comparison benchmark for compliance samples.
2. Compliance Sample — The applicant will sample directly outside the turbidity
screens surzounding the work area. and within the densest portion of any visible
turbidity plume.
If at any time during canstruction, turbidity levels directly outside of the turbidity screens
surrounding the work area exceed 0 Nephelometric 'I�rbidity Units (NTU) above background
levels, the applicant will imrnediately cease the operations that caused the turbidity and will
�� � modify the work procedures to reduce turbidity outside of the screens. The applicant will not
resume work until turbidity decreases vvithin acceptable levels.
During construction, the app�icant will submit daily monitoring reports on a weekly basis
to the appropriate DEP compliance officer for review. The reports will include:
� Pemut number
• Proj ect name
• Sampling and analysis date and time
• Turbidiry results
• Description of sampling rnethods
• Ma.p indi.cating the sampling locations
• Depth of water body -
• Weather conditions at time of sampling
• Tidal stage and direction of flow
� Wind direction and velocity
• Water temperature

�^� Environmental Considerations
l
Submerged Natural Resource Survey
AECOM environmexztal sta£�f perfozmed a submerged natuzal zesvurces investigation along the
project shoreline. The survey aimed to locate and characterize submerged natural resaurces to
assist in the development of a project design that avoids and minirnizes potential impact fo natural
resources to the greatest extent practicable. Palxt� Seach County Department of Environmerxtal
Resoi,u�es Management conducted an additional submerged resourees survey to monitor the
resources observed during AECOM's investigation.
AECOM environmental staff conducted the submerged resources survey on August 24, 2009, in
accordance with the methodology approved by NOAA Fishe�ries. The suxvey consisted of iwo
shore parallel meandering transects witlzin the limits of �he survey area and 15 shore-
perpendicular transects spaced at 140 foot intervals. Far the share-perpendicular transects, a
marked weighted line was placed along the bottom and divers recorded the distance frorn shore of
�.`� any submerged resources observed. If present, submerged resources were quantified at 15-foot
� intervals along each transect. Details of this survey are included in the Final Data Summary
Report (Attachment E).
Benthic conditions within the survey area consisted primarily of unvegetated sand. The survey
identified one small area of seagrass in the northern portion of the study area (Figure E-3). This
small seagrass bed consisted of very sparse (1-5% cover) Jol�mson's seagrass (Halophila
johnsonii� between 45 to 55 feet from shore. No other seagrass was observed during the survey.
Green feather algae (Caulerpa sertularioides} was foUnd as a very sparse patches throughout the
survey area. No shellfish beds were documented and the only hard-bottom habitat within the
survey area was limited to an existing rock pile at the southern erzd of the survey area that was
installed for shoreline pratection.
On August 17, 2010, Palm Beach County conducted a seagrass survey to verify the results of the
AECOM survey and monitoz the documented seagrass bed. Using differential GPS, the edges of
the seagrass were recorded. The resnits of the survey indicated the edges of the seagrass were
- consistent with those identifed in the 2009 survey, but the density had increased to 5-10% cvver.
,;, �
��- The proposed project has been designed in such a manner to avoid any impacts to this resaurce.
�---� The project is desi,gn.ed to enhance the submerged resources by creating 0.31 acres of protected
shallow water habitat for seagrass recruitment. In addition, 0.20 acres of mangroves will be
planted and 0.29 acres of high marsh will be esfiablished which czurently dces not exist. Another
0.85 acres of upland habitat along the edge of the high bank would be restored with native
vegetation. A planiing species list for these habitats and illustra.tion is provided as Attachment F.
Soils -
Soils on the project site are dominated by quartzipsamments and St. Lucie-Paola (Attachment G).
Seven bozings were performed along the alignment of the SR707 bridge irnmediately north of the
project site cirea 1967. Limestone was n.ot encountered within the depths explored up to
approximately 60 feet below sea level. In addition, medinm dense and dense sands were
generally encountered appraxirnately IS feet below the mudline. Upper soils have likely changed
due to channel dredging, b�t competent soils are Iikely present at depths useful for this project.
�-� In 2006, the US Department of Agriculture, Natural Resources Conservation Serviee, took 4
L borings along the area mapped as quartzipsamments and investigated the eroded bluff along the
ICW. The NCRS results and apinions were consistent with those associated with the 1967
analysis.
Additionally, Lwo borings were performed for the shoreline stabiiiza.tion efforts pernutted for the
Coast Guard Facility south of the project site. One of the borings ('T'B-1} encountered soils
similar to the SR707 project with medium dense sands encountered approximately 10 feet below
mudline. However, the second boring (TB-2) encountered loose and very loose sands to the
depths explored (approxirnately 30 feet below wa.terline}. TB-2 is located very close to the point
where the Indian River and the Loxahatchee River combine and tYte area of expected higher
erosion and dredging efforts. This loose soil candition may also exist at the southern portian of
the project area where the Tndian River channel is narrowest and the west bank has experienced
significant erosion.
Upland Environmental Survey
�=�-� On September 22 and 23, 2009, AECOM conducted a survey of the project site for presenoe of
jurisdictional wetIands, water bodies and listed speoies or potentially listed habitat. The survey
�� axea extended along the western shoreline of the Indian River from Beach Road bridge (U.S.
��---' AlA) south for approximately 1,540 feet to the confluence of the Loxahatchee River azxd Indian
River Lagoon. The inland extent of the survey aarea was 100 feet west of the shoreline ar 50 feet
west of the top of bank, which ever was greater. Descriptions of the plant communities and

Manatees have been observed using the waters adjacent to the JII..ONA shoreline as a travel
corridor. The narrowest sectaon of the ICW within the project area occurs along the northem half
of the shozeline. To avoid impacting the manatee travel cozriidoz, the northern breakwater
structures shall be located along the mean low water line to facilitate adequate clearance without
forcing manatees any closer to the ICW channel than current routes. In the southern section, the
shoreline has eroded up to 100 feet in 50 years, allowin.g gzeater separation between manatees and
boat traffic. The proposed project will create approximately 0.31 acres of protected shallow
water habitat that will provide a protected refuge for manatee use. The structures will be
separated by three gaps of approximately 20-25 feet from crest to crest to allow manatee access to
;.:� the isolated shallows. Manatees that iravel along the perimeter of the structures will still be a
xninimum of 75 feet away from the ICW channel.
Project conslrnction will apply standard manatee proteetion measures:
• The applicant, their consultant, or other appropriate persons will provide instructions to
all personnel associated with the project on the potential presence of manatees an.d the
need to avoid collisions with manatees. Construction personnel will take respoxasibility
for observing water-related activities for the presence of manatees.
• The applicant, their consultant, or othez appzopriate persons will inform all canstruction
personnel of the civil and criminal penalties for harming, harassing, or killing
manatees, mammais protected under the Manatee Mammal Protection Act {I972), The
Endangered Species Act {1973), and the Florida Manatee San.ctuary Act. Manatee
abservers stationed at the constructian site will provide full-time observation serv�ices
far protection of xnanatees.
• All vessels assoeiated with the construction pzoject will operate at "no wake/idle"
speeds at all times while in the consfxuction area oz in water where the draft of the
vessels provide less than a 4-ft clearance frorzx the bottom. The vessels will also follow
deep entry/exit routes whenever possible.
• Manatees observed within 100 yards of active daily construction will signal the
;__� implementation of aiI appropriate precautions to ens�e protection. These pzecautzons
' will include shutdown of operations for all moving equipment closer than 50 ft of a
manatee. Operations will not resume until the manatees had departed the project area of
� ^� their own volition.
� • Tliose colliding with or injuring a manatee will immediately notify the Florida Marine
1'atrol and the United States Fish and Wildlife Service.
• Temporary manatee awareness signs, posted b�fore and duri�g alI construction
activities, wili provide contact agency information for reparti.ng injuries or collisions.
Avoidance and Nlinimization Efforts
During the project scoping process, numerous design altematives were considered in efforts to
avoid and rninimize impacts to cultural and natural resources. Prehistoric and historic cultural
deposits were observed during cult�ual resources surveys conducted in 2009 and 2010 by
Archeological and Historical Conservancy (AHC). Due to the presence of cultural deposits on
the site, exca�vating the slope to create a natural angle of repose would potentially result in
unacceptable impacts. A single vertical sheet-pile system would also require excavation activities
to facilita.te placement of tie-rod and deadman system to support the structure. The preferred
design utilizes a tiered sheet-wall systern that minimizes the need to excavate. A letter of design
�
;� recommendations from AHC and summary of the 2009 assessment is availa.ble as Attachment H.
\ •
To avoid impacting the smaIl area. of seagrass observed during the 20fl9 and 2010 submerged
resource surveys, the placemexzt of rocks has been limited to approxixnately 13' east of the rnean
low water line, leaving a 20' to 25' buffer between the toe of the structure and the seagrass bed.
Other design alternatives that have been evaluafed are illustrated in Attachment I. With each of
these alternatives, the rock siructures extend down to the ICW channel depth iniroducing
potential for rocks to roll into the TCW channel during extreme starm events. The preferred
design uses a submerged toe-wall with fill to crea.te a perched shoreline to serve as a flat
foundation for the breakwater. T'his elevated alternafiive eliminates the potential for rock
displacement into the ICW channel and creates shallow water ha.bitat landward of the structures.
To minimize impacts to rnanatees, the preferred altemative lea.ves 20' gaps between the rock
structures to provide manatees access into the protected shallow water habitat.
`� � `'\�
�� General Construction Schedule and Techniques
1 ._ .1
Ta pzotect adjacent natural resources, before beginning any work, the applicant shall buoy-mark
the adjacent seagrass bed. These features will serve to inform construction personnel to avoid
activities in these areas. Throughoat the project, appropriate turbidity control devices will prevent
turbid waters from entering the Jupiter Inlet, the Indian River, or adjacent resources. The
applicant wi11 stage wozk and store equipment and materials on federally-owned property within
the JII.,ONA boundaries.
The project will cammence with reznoval of exotic vegeta.tion along the shoreline and creation o£
a construction cozridor, upland of the shoreline and along the top of the bluffs. The applicant will
utilize this corridor along the top of the bank to install the tiered sheet pile system. Due to the
presence of buried cultural resources, any work that would require disturbing t�e ground surface
will be znonitored by an azcheologist.
The 5 breakwater structures along the north end of the pzoject may be constructed using heavy
r ,� equipment staged from the adjacent canstruc�ion corridor. 'Tlie three sonthem structures wi11
� require a barge, loaded at the north east boundary of the property then floated to the placement
location.
Most work staging will occur on the upland property adjacent to the site. Where necessary, work
wi11 proceed from barge. Project specifications sha11 require construction vessels maintain a
minimum'one-foot clearance from the bottom at alI times during conshlzction.
Trze project specifications will require the applicant to proceed witk� work in such a rnanner as to
allow continued safe public navigation of the ICW. Means and methods ta maintain safety and
prevent accidents may include safety signage, lighting, buoys, the use of whistle signals, and
ship-to-ship radio communications. Where necessary, the applicant shall request assistance from
local law enforcement or the coast guard to direct navigation and maintain public safety.
Constraction matezials will primarily include vinyl and steel sheet pile, limestone boulders and
natural(saud) materials. Wherever possible, the applicant will incorpozate construction materiais
,
`� into the proposed slructures as soon as practical to minimize the need for on-site stack piles.
`_.! } The construction project will proceed with the following activi�ies:
• Sheet pile placement: The contractor will place sheet pile thraugh a combination of the
typical jetting, driving, and vibratory installation means and methods.
• Fill placement: The FiND contractor for a future ICW maintenance project would
divert material dredged from the TCW channel to the designated fill iocation landward
of the subrnerged toe-wall
• Rock placement: A long stick excavator would be used to place rock to meet the
specifications of each breakwater segment. For the southern segments that are fiu
offshore, a barge wil1 �ansport the rock and sexve as a workiug platform for tlze
excavator
The Bureau of Land Management desires to begin consfruction in April 2012. Construction
efforts will likely span six months and follow the raugh timeline below:

Dear Ms. Poppell:
On May 8, 2008, Public Law 1 I 0-229 established the Jupiter Inlet Lighthouse
Outstanding Natural Area (ONA), designating it a unit within the U. S. Departmen#
{ of Interior, Bureau of Land Management's (BLiVn National Landscape Consezvation
�`-�'' System. Of the over 850 units within the National Landsca.pe Conservation System,
the Jupiter lnlet Lzghthouse ONA is the only unit east of the Mississippi River. The Jupiter
Inlet Lighthouse ONA is located at the confluence of the Lvxahatchee River and the Indian
River Lagoon (Intracoastal Waterway} and �ncludes almost a nule of riverfront shoreline.
BLM is in the process of eva�ua.ting engineeri.ng design options to stabili�e a section of the
°�east shoreline of the Jupiter Tnlet Lighthouse ONA (Figure 1). As a part of the stabilization,
it is being proposed that the shoreline be extended out up to 65 feet from the existing shareline.
Of note, BLM has documented that the southem portion of the proj ect site has lost more
than 100 feet of land along por�ons of this shoreline over the iast 50 years.
In order ta determine the potential site constraints to be consi.dered during the design phase
of the shoreline stabilization project BLM and AECOM, the project's engineering and
design contractor, hosted a pre-application meeting with the Southwest Florida Water _
Management District, U.S. Army Corps of Engineers, and members of the Florida Department

of Environmen�al Protection's Office of Coastal and Aquatic Managed Areas, and others.
The BLM anticipates filing an Environmental Resource Permit (ERP) application foz the
project in 2010. It was suggested during the pre-application meeting that BLM should
� request a ti#1e check of the proposed affshore project area from the Division of State Lands
prior to submitting the ERP application. The purpose of this letter is to make the title
detenmination request. The results of the title check will be incozpozated inta the ERP
application.
If you have any questions or require any additional information, please feel free to
contact our Field Biologist, Faye Winters at 601-977-5431 and/or Allen Brooks with
AECOM at 727-577-5430.

� Executive Summary
The Bureau of Land Management required engineering design services, as well as support
during the public and regulatory review process, for a shoreline stabilization praject in Jupiter,
Florida in northern Pafm Beach County. The project area is locatec! along approximately 1,540
feet of shoreline at the cor�fluence of the Loxahatchee River and Indian River Lagvon,
approximatefy fl.5 miles west of Jupiter [nlet. The shoreline is lacated on #he wes# bank of the
Indian River Lagoon, which also serves as the ]ntracoastal Waterway. Approximat�ly 700 fee#
of #he shoreline is in active erosion, exacerbated by overland runofF, heavy public use, and wave
action.
fn order to achieve a viable design concept, site surveys needed to be performed at the location
of the proposed projec#, as well as its surrounding areas. These investigations included
Onshare and Offshore Environmental Surveys, a Topographic/Bathymefric Survey, a
Geotechnica! Data Review, and a Cultura! and Historical Resources Survey Review.
Preliminary Hydrodynamic Modeling was also carried out for the project.
The Onshore Environmental Survey resulted in ver'rfying the presence of such invasive species
as Brazilian pepper (Schinus terebinfhifolius} and Australian pi�e {Casuarina equisetifolia}. In
addition ta the several invasive species present, red, black, and white mangraves (Rhizophora
mangle, Avicennia germinans, and Laguncularia racemosa, respectively) were also observed
within the survey area. However, despite many protected species known to occur within the
� ONA, no listed species were observed wit�in the project area duri�g the survey. Only one
abandoned gopher tortoise burrow was seen, but #he tortvise itself was not present.
The Offshore Survey indicated the presence of a small patch of Johnson's s�agrass {Halophila
johnsonir� located within the northern portion of the survey area. Other than Johnson's
seagrass, no a#her seagrass species were observed during the survey. In addition, no shellfish
beds were documented, and hard-bottom �abitat within the ofFshore survey area was limited to
the existing rock pile at the southern end of the survey area.
The to�ographic surveys collected at the site showed that eleva#ions at the project site ranged
from 14 feet to 23 feet basec! on the Narth American Vertical Datum of 1988 (NAVD 88).
Existing bathymetric data was received from the Fforida Inland IVavigation District {FIND)
providing elevations of the Indiar� River channel adjacent to the site. The bafhymetry data
col�ected along the extents of the projecf �imits matches with the data provided by FIND.
The Geatechnical Review showed that limestone will not be encountered within the depths
needed fior any stabilization option. A range of sands (very [oose, loose, medium dense, and
dense) were encountered with the upper 15-30 feet below the mudline, but these should be
competent soils for this project. Recommendations for additional geotechnical data collectian
were made for both shallow and deep stabilization methods. For shallow vr surficial methods,
� physical characteristic soils testing for compatibility and erosion analysis will likely be required.
For deeper systems, such as sheet piles, drilling test borings may be necessary to obtain
information such as depth to limestone or other hard layer, soil density, strength and other
� J characteristics. �
The Preliminary Hydrodynamic Modeling effort depicted the tida! fluctua�tions abserved at the
site during normal and extreme climate canditians. Results from this phase of the analysis

�� showed maximum velocities of 2.6 ftls, 3.4 ff/s, 3.3 ft/s, and 3.2 ffls in the intertidal zone of the
existing eonditions and alternative treatments 1, 2, and 3, respectively, during the extreme event
scenarios. The combination of a 25-year storm surge and a 25-year rainfal! eaent produced
only s[ightly higher velocities and a slight�y higher peak water surFace elevation than a scenario
with only storm surge. Also a slightly higher maximum water surface levef at the shoreline near
the confluence af the Intertidal waterway and the Loxahatchee River was predicted.
The Cultural and Historic Resources Survey Review recommended that the propased bank
stabilization consider an alternative that does not ir�clude excavation, but does include adding fill
sediments to these sensitive areas. Stabilization methodology for the bank along the area
northward will have more flexibility in regard to cultural resources. � .

1.0 lntroduction
�� .
The Jupiter Inlet Shoreline Restoration project site {"project site") consists of approximately
9,54Q teet of shoreline adjacent to the Atlantic Intracoastal Waterway (AIWW) just south ofi State
Road 707 bridge and 0.5 miles west of Jupiter Infet in Jupiter, Florida. The project site
specifically includes the west banEc af the Indian River between the car�f[uenee with the
� Loxahatchee River to the south and Beach Road bridge to the north (see �igure '! in Appendix
A).
The project site and its acljacent areas were congressionally designated as the Jupiter Inlet
Lighthouse Outstanding Natural Area (ONA) on May 8, 2008. Based on the congressianal
mandate, the Iegislative requirements for #he site are:
"The Secretary, in consultation with fhe Local Partners and fhe Commandant, sha!! �
manage fhe Outstanding Natura! Area -- as part of fhe National Landscape
Conservafion System; in manner thaf conserves, protects, and enhances the unique
. and nationally important historical, natural, cultural, scientifrc, educational, scenic,
and recreafional values of the Outstanding Natural Area, including an emphasis an
the restoration of native ecological systems."
The project site is under the respansible control of the US Coast Guard and is esserrtially
undeveloped natural space. However, the project site is slated to be tumed aver to the Bureau
of Land Management (BLM) in the near future.. Due to a variety ofi impacts including necessary
�`1 dredging o� the channel to maintain access, overland flow, wave action, storm impacts, and
`•J recreatianal use, signi�cant bank loss has resulted over the past 30 years, up tv 140 feet over
the last 50 years. Therefore, the BLM has contracted EDAW�AECOM to evaluate the project site
and develop conce�tual engineering design options ta s#abilize the shoreline and res#ore
habitat.
In order to assess existing conditians and determine some of the potential si#e constraints that
should be considered during conceptual design dev�lopment, AECOM was contracted to carry
out various studies and surveys o# the projec# site. This data summary report summarizes the
• results of these studies and surveys, and wi�ere appropriate provides guidance and
recommendations for the caneeptual design development. ln addition, separate reports wilf be
prepared as necessary for future regulatory permit submission. The investigations and analyses
incfuded onshore enviranmental surveys, offshore environmental surveys, topographic and
bathymetric surveys, a geotechnieal data review, preliminary hydrodynamic madeling, and a
cuitural and historical resources survey review. - .
At this time, only the exis#ing models have been developed for the preliminary hydrodynamic
modeling; the propased modeling results will be su6mitted as an addendum to this report. A
geotechnical review and assessment is stifl ongoing as requested data is not yet availabfe from
local agencies. AECOM will also review and s�mmarize the cultural and historical resources
survey tv be undertaken by BLM in t�e near future. These sectior�s are marked as placeho[ders
for this draft and will be provided as an addendums at a later date.
�' [t is also importan# to nate that the Draft Management Plan and Environmental Assessment
'`� prepared by the BLM #or the Jupiter Inlet Lighthouse ONA is another specific reference
document that is being utilized in ti�e development of the conceptual designs.

The main channei of the Waterway in this area has a Class II I designation and is part of the
Outstanding Florida Waters {Florida DEP; 2008). In addition, the channel adjacent #o tMe
project site is par� of the Manatee Pratection Area and is designated manatee critica! habitat.
Th� submerged lands of the proJect site are state owned and lie within the Jensen Beach to
Jupiter Inlet Aquatic Preserve (see Subm�rged Lands Tit[e D�terminat�on, Figure 30 in
appendix A).
AECOM conducted a survey of the project site for the presence of jurisdictional wetlands, water
bodies, and listed species Qr potentiaAy listed species habitat. The survey area extended along
the western shoreline of the [ndian River from Beach Road br�dge (U.S. A1 A) south for
� approximately 9,540 feet to the confluence of the Loxahatchee River and Indian River Lagoon.
The inland extent of the survey area wa� '[00 feE# west of the shoreline or 50 feet west of the
top of bank, which ever was greater.
Methodo/ogy
The project site was �rst assessed through review of published infQrmation and Flarida's
database of species occurrence records. Prior to conducting field investigations AECOM
conducted a desktop review of the fo[[owing material to prepare for the pedestrian survey:
1. U.S. Fish and Wi[dlife Service (USFWS} and Florida Fish and Wildfife Conserva#ion
Commission (FWC) lists of rare, threatened, and endangered plan# and animal species;
` ' l 2. The BLM Draft Management Plan and Environmentat Assessment for the Jupiter
�J Lighthouse ONA (2009), which includes a review of federal and state protected species
that have been documented at the ONA;
3. USGS 7.5-minute Topographic Quadrangle Maps;
4. USFWS National Wetland lnventory (NWI) Maps; and
5. Aerial Photographs.
Field visits to ground truth the on-site vegetative communities were conducted on September 22
and 23, 2009. As par� of the investigation, transects were wa[ked throughout the survey area.
The presence of listed species was evaluatEd through ac#ua[ observativn, signs of scat, prints,
or other indications of their presence or utilization of the site. The approximate lim�#s of
wetlands and surtace waters were evaluated based on the criteria de#ined in the Wetland
Delineation Manua! {USACOE 1987) and the Delineation of the Landward Extent of Wetlands
and Surfaee� Wafers (Chapter 62-340, Florida Administrative Code}. A lis# of representative
plant species observed within the survey area was also recorded. ln addition, land use was
classifed and mapped using #he Florida Land Use, Cover and Forms Classifrcation System
(FLUCFCS), Level IlI, {FDOT 1999). �
Plant Community
A 20-foot vertical bluff stands in the southeast section of the site, sloping to lower elevations as
the land progresses to the northeast. Tropical hammock that trans�tions to disturbed xeric pine

C� the Indian R9ver}. However, as noted above, red, black, and white mangroves {Rhizophora
1 mangle, Avicennia germinans, and Laguncularia racemosa, respectively} were present within
the survey area (see Figure 3 in Appendix A). Mangroves have been afforded specific
protections under the Mangrove Trimming and Protecfion Acf, and any proposed impacts to
these plants as part of this project will be reviewed by the State of Fiorida's Envirortmental
Resource Permit Application process.
Profecfed Species
An inventory of the listed species potentially occurring within the survey area was generated
based upon a review of USFWS and FWG protected species infarmation as well as the 2049
BLM �raft Management Plan and Environmental Assessment for t�e Jupiter Lighthouse ONA
� (sEe Table 2). Many protec#ed species have been no#ed to oecur within the ONA; however, no
listed species were observed within the survey are�. The survey area ha� been disturb�d
t�rough recreational use, which has decreased its q�uality of habitat for protected plant and
animal species. One inactive goph�r tortoise {Gopherus polyphemus) burrow was observed
adjacent to the project site, approximately 50 feet to the southwest of the project site. Additiona[
information concerning the gopher tortoise is provided below. No animal tractcs, burror�vs, scat,
or other indica#ions of the presence of listed animals other than the gopher tartoise were found
during the field reconnaissance.
Rlease note that offshore protected species are included in this table as well.

I n addition #o the fie[d survey, AECOM conducted a bald eagle (Haliaeetus leucocephalus) nest
search of the FVI/C's eagle nest database (FWC, 2009) to identify potential off-site nest
locations. The study area does not fall within the protection zone of any documenfed eagle
� nests. Similarly, the BLM indicated that their review of the FWC records did. not include any
recently documented accurrences o'f scrub jay (Aphelocoma coerulescens) in the vicinity of the
projeet site. A review of the most current FWC Water Bird Locator database revealed no record
of a wading bird rookery in the vicinity of the study area (FWC, 1999). The shor�line of the
Indian River could provide foraging habitat for some listed wading birds, but the FWC does not
regulate impacts to wading bird foraging habitat or areas occasionally u#ilized by listed birds.
The gopher tortoise is listed in the state of Florida as threatened and is the only tartoise found in
the eastern U.S. as well as only one af faur tor�oise species found in North America. This
species occurs throughout the state, including Palm Beach County. The gopher tortoise is a
medium-to-large terrestrial turtfe with spade-like front legs adapted for digging and elephantine
hind legs. The historic habitat of the Gopher Tortoise is xeric, fire-dependen# communities such
as longleaf pine-turkey oak associations located on sand ridges. Other communities u#ilized by
the tartoise include pine and oak scrub, sandhills, live oak hammock, pine flatwoods, and dry
prairie habitats. In many areas of the state, these habitats have been sign�cantly altered, and
the species may also be found in habita#s such as utility rights-of-way, fence rows, pastures,
and field edges. The general characteristics of suitable habitat are loose, well-drained sandy soil
for creating burrows, herbaceous matter for foraging, and scattered open sites for nesting
(Deimer, '1992). The listed status of the gopher tortoise affards it special protections under rules
68A 25.002, 68A-27.005 of the Florida Administrative Code. The FWC requires that a gopher
tortoise managemen# plan be approved prior to any cons#ruction that may harm gopher tortoise
or their habitat. Gopher tortoise management pla�s may include any one ar a cambination of
the fiollowing alterrtatives:
�-� • avoic� burrow entrances by at feast 25 feet;
� • capture and relocate the gopher tortoises to an on-site preserve; or
• capture and relocate the gapher tortoises to an approved off-site location.

The avoidance of all the gopher tortoise burrows appears to be the most feasibfe alternative for
�� shoreline stabilization within the project site given the location of the abserved burrow away
_ from the propvsed construction activities. 1n order to implement this alternative, prior to the start
of construction all gopher tortoise burrows should be marked and temporarily corralied by s�lt
fence to establish a protection zone during construction. If deemed necessary at that time,
authorizafion from the FWC would be required prior to any refvcation ac#ivities. The gopher
tortoise is currently under status review by #he U.S. Fish and Wildlife Service and coordination
with that agency will aiso be required.
The Florida mouse (Podomys floridanus), Eastern indigo snake (Drymarchon coriacea), and
gopher frog (Rana capito) are protected species corr�mon[y associated with gopher tortoise
burrows. These species are rare, very reclusive and not general{y observed during feld
reconnaissance. The FWC generally aufhorizes tt�e relocation of thsse species along with any
gvpher tor�oise relocation permit. Na specific coordination with the �WC is anticipate� for these
species. However, the USFWS will like(y require #he implementafion of Standard Protection
Measures for Eastern Indigo Snake during construction (USFVIIS, 2004).

�� 3.0 Offshore Environmentai Survey
�
To identify any submerged resaurces within the project site, an afFshore survey was perFormed
on Augus# 24, 2009. The survey was conduc#ed within an area d�ned by the shoreline to the
west, the AIWW channel to the east, and the project boundary limits to the north and south.
Mefhodology
The survey was conducted in accordance with the methodology described by the Halophila
johnsonii Recovery Team (NOAA Fisheries, Accessed 2009}. Specifically, a preliminary visual
reconnaissance of the survey area was first conducted to locate any accurrences of submerged
aquatic vegetation (SAV), shellfish beds, cora[s or live/hard-bofitom. Reconnaissance consisted
of slowly towing a diver along finro shore-parallel meandering transects within the limits of the
survey area. Subsequently, a more intensive survey was co�dueted atong a series of shore�-
perpendicuEar transects across the sntire survey area. The survey transects were spaced at
104-�oot intervals and a total of 15 #ransects were surveyed. Along each transect, a weighted
and marked �ine was laid along the bottom and scient�c divers recorded the distance from
shore of submerged resources as they swam afong each transect. Submerged resources, if
present,- were quantified at 15-foot intervals alvng each transect. �
Submerged Resources
The offs�ore survey area was found to be largely unvegetated. Johnson's seagrass (Halophila
johnsanir� was ider�t�ed within a small area within the northern portion of the survey area (see
� Figure 4 in Appendix A}. This species was found between 45 to 55 feet from shore, but was
very sparse and was represented by only a few scattered and isolated shoots. Johnson's
seagrass was federally listed as threatened in 1998 and E's only found along the sautheast caast
af Florida betweerr Melbourne and Key Biscayne with its primary habitat occurring in the Indian
River Lagoon.. Within the lndian River Lagoon, it is found from Sebastian Inlet south (Littler et
al., 2008). Johnson's seagrass occurs in shallow water to a depth of approximately six feet and
has a preferenc�: far sand substrate {Smithsonian, 2009a}. Divers estimated that within the
mapped area, the percen# caver of Johnson's seagrass was approximately one percent.
Other than Johnson's seagrass, no other seagrass species were observed during the survey.
One other species of SAV, green feather alga (Caulerpa sertularioides), was found as a very
sparse covering throughou# the survey area. This green alga occurs throughout the Indian
River Lagoon, often carpeting the lagoon bottom, jetties and seawalls. The green feather a[ga
is generally found in shallow-water ofi 33 fee# or less and within sandy areas, se�grass beds, or
on mangrove prop roots (Smithsonian, 2009b}. Approximately 35 species and varieties of the
genus Caulerpa occur within the Caribbean and western Atlantic and some ather Caulerpa
� species, C. taxffolia and C. racemosa, are noted to be highly invasive species within seagrass
beds (Sfafford and Bell, 2006). Caulerpa species primariiy reproduce fram fragmentation and
due to the production of bio-adhesives can attach to both unconsolidated and hard substrates
after drifting in the wa#er column. When they accur, sexual reproduction events are rapid and
may last no longer #han 36 hours. Although the species may pravide habitat, many marine
organisms may find the green feather alga unpalatable due to the presence of chemical
compounds (Smithsonian, 2009b).
, J No shellfish beds were documented and hard-bottam habitat within the offshore survey area
was limited to the existing rock pile at t[�e southem end of the survey area. The U.S. Coast
Guard had presumab[y installed the rock pile for shoreline protection. A varie#y of macroalgae

of this area was considered to be insigni�cant. '

� 4.0 Topographic/Bathymetric Surveys :
AEC�M collected tapagraphic and bathyme#ric survey data at the project site. The survey area
was the same as for #he onshore environmental survey, extending along the western shoreline
of the Indian Riverfrom Beach Road bridge (U.S. A9A) south far apPraximately 1,540 fee# to the
carr�luence of the Loxahatchee River and [ndian River Lagoon. The inland extent of the survey
area was 'i00 feet west from the shoreline or 5� feet west of the top of bank, which ever was
greater.
Photos were also taken of the shoreline to document existing conditions of the project site. A
representative selection of these images can be found in Appendix B. In addition, the results of
the topographic survey were verified in the field by AECOM staff.
Methodology
The survey points were collected at approximately 50 foot intervals and record�d based on the
NAVD 88. The horizontal datum referenced was the Florida Stat� Pian Coordinate System,
Transverse Mercator Project, East Zone, North American D�tum af 1983/9 990 acljustment.
Since the Fforida INand Navigation District (FIND} provided the BLM with recent bathymetric
data {FIND, 2008) for the Indian River adjacent to the project site, it was determined that i#
would be most efficient in this eonceptual phase to collect supplemental topographic and
bathymetric data. AECOM is curren#ly utilizing the FIND data and the supplemental data �
collected to create a digital terrain model of the project site, shawing contours at 1-foot intervals.
This 3-D model wilf be utilized as the baseline for the cvnceptual designs.
'�-
!n the next final design pnase of the project, it will likely be necessary to complete a separate
and complete topagraphic and bathymetric survey of the project site that will be signed and
sealed by a Professional Surveyor licensed in the State af Fiorida. A signed and sealed survey
will be necessary for the construction bid documents and may alsv be required by some or all of
the regulatory agencies. �
Project Site Description
The contours generated from the survey data extend from approximatefy 3� feet onto the Coast
Guard property in the south and continue north to within approximately 35 feet of t�e State
Road 707 Bridge. Contours leading tv State Road 707 in the northern part of the site are at 33
percent slope until they connect the existing grade #o the roadway. Moving south, grades
achieve a more a gradual slope of 2.6 percent for lands above the shoreline in the northern half
of the site. Approximately midway along the project site a bfuff appears and has an average
slope vf 45 percent or 1 vertical foot for every one horizontal foat. The uplanc! side of the bluFf �s
shown to have a gradual slope ofi 10 percen# or less in most areas and obtains an efevation of
23 feet within the surveyed area. However, areas along the shvreline possess slopes of 90
percent or greater beginning at around elevation 9.
Along the ent�re project length, contours below the shoreline have an average slope o'f
approximately 94 percent. However, at the shoreline, there are areas with 90 percent slopes,
,� mostly occurring in the northern portion of the site. The slope at the southern tip of the si#e is
covered by a concrete cap that extends under the fence over orrto the Coast Guard property.

5.0 Geotechnical Data Review and Evaluation
��
As a subcontractor to AECOM, CTL(Thompsan has performed a review of avaifable
geotechnical informa#ion in and around the project site, including a field visit to the project site.
Based on the initial review and project site visit, CTL�Thompson has prepared a preliminary
conceptual evaluation of the geotechnical issues and anticipated requirements af the project,
with the understanding that more robust and detailed geotechnical inspections and/or ana[yses
wifl likely be required in the next final design phase of the �roject. Reeommendations for
additional inspections and analyses are provided. Due to the constraints of the project site, it is
fairly apparent that only several engineering designs wiil be passible, t�erefare, it was possible
to provide a fairly in depth preliminary evaluation. Assumpt9ons and anticipations have been
stipulated wherever appropriate.
Available lnforma�ion
Data that was obtained and reviewed incfuded discussions with representativ�s of F1ND
regarding historical channel dredging, the boring data from the original construction of the
SR707 bridge at the north of the projeet (from Palm Beach Cour�ty archives, dated 'f 967), and
the "Report af Subsurface Exploration Shoreline Stabitization Project" (Dunkelberger
Engineering and Testing, Inc., dated November, 2009j for the US Coast Guard facility to the
south of the project area. A summary of this data �nd how it relates to the project site is
detailed below.
, During a September 24, 2009 praject meeting in Jupiter, FIND provided some limited verbal
� information regarding tF�e channel area resulting from experience dredging the channel. Whife
fhis informa#ion was general and not fully documented, it is useful none-the-less. According to
FlND, in general, dredge spoils are deposited along the nearest riverbanks and genera(ly
consist af uniform fne sands. At one time, the targe# elevation for the channel bottom for
dredging operations was approximately elevation -14.0'. Currently, the target efevation has
decreased by a few feet. Based on the FEND represen#ative's recolfection, there were not any
incidents of hard bottom encountered during dredging, which suggests limestone is deeper.
Seven borings were perFormed along tE�e alignment of tne SR707 bridge immediately north of
the project site. The informatian is relatively old (circa 1967), so bEow count iriformation in the
upper soils is likely dififerent due to channel drec[ging over time. However, it is ele�r #hat
Gmestone was not encountered within the depths explored up to approximately 60 feet below
sea [evel. In addition, medium dense and dense sands were genera[ly encountered
approximately 15 fee# below fihe mudline. Again, upper soifs have likely changed due to
channel dredging, but competent soils are likely present at depths useful for this project.
Two borings were performed for the shoreline stabilizatian efforts for the Coast Guard Facility
south of the project site (see Figure 5 in Appendix A}. One of the borings (TB-1) encountereci
soils similar to the SR707 project with medium dense sands er�countered approximately 10 feet
below mudliRe. Hvwever, the second boring (TB-2) encountered loose and very (oose sands to
the depths explored (approximately 30 feet below waterline). TB-2 is located very close to the
point where the Indian River and the Loxahatchee River cambine and the area of expected
,� higher erosion and dredging efforts. This loose soil condition may also exist at the southern
portio� of fhe project area where the Indian River channel is narrowest and the west bank has
experienced significant erosion.

`-� Projecf Site �sit
CTL�Thompson visited fihe project site on September 24, 2009. Site observations were made
from locations off the project inc[uding the Beach Road Bridge and Dubois Park. A# the time of
the s�te visit, very little of the sand bank was exposed along the project section of the river. The
wooded growkh �xtended intv the water in most areas. Tidal changes in river elevation were
minimal as the river drainage period exceeded the !ow tide window, resulting in minimal change
in exposed river bank over tidal filuctuatian.
Bank soils are typical silty fine sands common to the intercoastal waterways and the local area.
With the prevalence of tree growth at the edge of the river and the dense woods along the site,
a significant organic content is anticipated in soils along the bank and in the waods. Organic
materials may exist in same areas of the submerged river bottom soils, but due to the regular
� dredging efforts and river erosion, organic content of the river bottom soi[s is anticipated to be
low.
A review of the F1ND bathymetric da#a indicates the river bottom slope from the bank ta the
dredged channel is relatively steep, primari[y due to the proximity of the channel to the project
site. Steep, submerged slopes of silty sands common in this area are typically prone to erosion,
in both the down current and cross current directions. Channel dredgir�g can mitigate the cross
current erosion, but over time the sand makes a general migration down river. Bends in the
river and other channel shape variations lead to areas of increased water velocity and
,� turbulence, increasing erosion or soil transport. �
�. �
Preliminary Conceptua! Evaluation
Critical Information: Geotechnical information that wil! be critical to this project will depend
some on the selected preferred alternative: Regardless, two primary concerns wilf be soil grain
size analysis and soil density. The grain size analysis would indicate soil transportability and
ervdibility in connection to surficial bank stabilization efforts. The sail density information will be
needed to assist design of deep soil retention systems.
Geotechnical Exploration: The appropriate scope of geotechnical explaration for this project
will also depend on #he selected preferred a{ternative. Deep soil retention systems will require
more testing and explaration than sha(lower systems. .
{f the stabilization methodolagy consists of a shallow or surFicial method such as the instailation
of rock armor, a testing program would likely consist of prvvEding soil characteristic testing of the
bank soils for compatibility and erosion analysis. Samples of river bank material would be
collected at discrete lacations along the length of the praject site using shovels. These samples
would be analyzed in our laboratory to quantify materiai properties specific to #he analysis needs
vf this project. In generai, this would include grain size distribution, organic content, and
possibly hydrometer and compaction testing if necessary.
A significant amount of geotechnical irlformation is available from adjacent sites (i.e.
aforementianed US Coast Guard praject site and the SR707 Bridge). This irafarmation could
��� provide the basis for the design of a deep soil retention system such as sheet pile, provided the
'`-- BLM is willing to accept a more conservative sheet pile design — i.e. excessively deep, soft soifs
requiring longer sheet piling. If the is not acceptable, borings on site would be essential.
Borings would provide data such as determining depth to limestone or other hard layer (if it

,.._°.__,_�_.��---�--- ^--------- ^--°--. ,� �_�._..__.,., ..,,,..
�� exists), soil density, strength and other soil characteristics. These borings would need to be
_ eollected at the specific Iocations where sheet pile would be installed.
For the slope stabilization, the sheet piles would bc� Iocated just out of the water parallel the
shoreline. Based on experience with similar projects and the local geology, 3 to 4 borings afong
the length of the sheet pile section should be appropriate. With the limited accessibiliiy of the
site, and to minimize site disturbance, these additional borings would need to be performed with
labor intensive, hand-carried equipment. CTL�Thompson maintains a relationship with a Florida
based drilling provider who specializes in difficult access services and equipment and would be
capable ofi performing this testing if necessary.
Following the collection and testing of the field samples, the data would be reviewed and
analyzed. A geotechnical report would be prepared that outlines the field testing scope and
testing results, along w�th design and construction recommendations for the preferred design
alternative. A review of the final design drawings wouid be recommended to ensure
geotechnical design criteria is properly addressed.
Recommendations for different testing scope or analyses may be required depending on the
. preferred afternative design.
Conceptual Design Expectations: There are two different por�ions of the shorefine that need
to be stabilized -- the shoreline and the adjacent upland slope. Based on the stakehalder
meeting discussion, agency comments, and obvious site constraints, two general conceptual
� measures appear most appropriate for stabilization at the pro}�ct sit�:. Qne option is a shallow
C _,! system of armoring; the second is a deep structure likely consisting of sheet piles. Both sheet
piles and armoring are being cansidered for slope stabilization, but for the in-water shoreline
stabilization, only armoring is being considered. The preferred aiternative will likely include a
combination of these measures.
For shoreline stabilization, the shaf[ow armoring would generally consist of �ddin� some type of
riprap or boulders, continuous or intermittent fashion, along the project shoreline. From a
geotechnical perspective, this option requires mir�imal engineering design support. Tl�is system
is relatively insensitive to setttement soil movements immedi�te to the structure. The fine sar�ds
at the site wi8 generaliy not be erosional[y similar to the armoring ma#erials, so localized.erosion
from between the armoring can occur. Selection of armoring size and placement will be
importan# to prevent materials from migrating into the navigation channel. .
The steep grade of the subsurface soils be#rnreen the bank and the dredged navigation channel
are an additional concern for #he shallow armoring option. Armoring witl not extend to cover the
entire subsurface slape, but rather the near shore region. Erosion of the slope area befow the
armoring could continue, possibly to the point of destabilizing the armoring ma#er�als, allowing
them to migrate toward ar into the channel. The breakup o# the armoring would reduce its
benefits and possibly eause problems with future channef dredging operations, The timeframe
of this occurring would be impacted by a wide varie#y of outside influences including s#orms,
river current fluctuations, channel dredging efforts, etc. Coordination of the geotechnical
analyses and hydrodynamic modeling results wilE be imperative to avoiding these issues in the
�� proposed design.
The second option, a deeper stabilization struc�ure such as sheet piles, would generaUy consist
of installing the sheet piles at the xoe of s[ope of the adjacent upland slope. Both a single length

� of sheet piling and a double, tiered design are being considered. .Sheet pile design will depend
�, � greatly an the retained soil heighf and, again, potential scaur around the piles. Additianal pile
length may be required to provide adequate retaining capacity in #he event of significant scour
erosion, Coordinatian of #he geotechnical analyses and analysis af the stormwa#er runoff
conditions along the slope will be imperative to avoiding these issues in the praposed designs.
Based on the available geotechnical ir�formation, the site is favorable to the use of sheet piling
for slope retention. Generally the sands encountered have increasing density with depth and no
cemented lenses or fimestone were encauntered at depths that will likefy irrfluence this project.
Some data suggests the po#ential for �oose soils at the southern end of the pro�ect which may
necessitate longer sheet piling. .
Construction: Experience with similar canstruction suggests the work would likely be
perFormed with a combination o# land based and barge�based equipment. This would allow the
construction contractar freedom of movement over the river worksi#e with minimal disturbance to
the existing adjacent upland. We understand an access road will be constructed at the top of fihe
slope to allow installation of sheetpile and for soil grading. Maintenance and possibly �
stabilization of the road surface will be essential as much of the equipment will be reaching
down the slope applying higher ioads at the edge of the raadway. Deep structure systems
, could be installed by barge based equipment, but mare likely land based equipmerrt and likely a
crane with a swinging hammer. Sheet piles are typically driven in place using either a vibratory
or impact hammer. Vibratory would be significarrtly quicker, but the impact on wa#er quality from
disturbed soil would need to be evaluated, as would noise impacts on the site from different
�� driving hammer styies.
L
Water based cons#ruction, such as armoring placement, will likely be performed from barges
held in place by either anchors ar spud systems. Spudding is typica[ly the preferred option as it
�= provides the eantractor better location stability with ease of use.
Armoring materials for a.shallow option would be transported to the site by barge and then
placed with either backhoe or crane equipment stationed on a barge.

�-� 6.0 Preliminary Hydrodynamic Modeling
..�
AECOM utilized MIKE21, a two-dimensionai model capable of assessing the tidal nature of the
project site, to develop preliminary hydrodynamic models for the existing s�e conditions. The
modeling results established by this preliminary assessment were �sed to evaluate the conceptual
design alternatives, provide guidance for developmen# of shorefine protection and restoration
strategies and techniques, and assist in determining which option is best suited to meet the
objectives of the project. A more detailed technical report of tl�e modeling resuits has been
prepared; this section represents a synopsis appropriate for the level of this data summary report.
Methodology & Sefup .
Data Collection: Several data collec#ion tasks were performed to determine the extent of the
existing hydrodynamic model o� the Jupiter Inlet for the cvncep#ua! phase. A review of the
available existing literature was condueted to understand the characteristics of the project site
and to determine the extent of the data co[lection task. Several studies in the vicinity of the
project area have provided significant ir�formation to develop the hydrodynamic model. Primary
sources of data were:

Datum: The horizontal reference datum for the project is NAD83 UTM Zone '! 7N (Meters). The
vertical reference datum is NAVD88 (Meters).
Model Extent: The extent of the model grid far the project site was selected #o represent the
bathymetry of the Loxahatchee River ar�d Indian River at the Jupiter Inlet. The exten#s of the
model bo,undaries were chosen to include alf #idal and freshwater irrFluences in the �roject site.
This includes tidal iriflows from the A#lantic Ocean at the Jupiter Inlet and freshwater inflows
from the Loxahatchee River watershed. An overview of the �rojeet site on a regional scale
showing the exterrt of the model grid is presented in Figure 7 of Appendix A.
Three model baundaries were included in the model grid. The northem boundary of the model
extends approximately two miles upstream of the Indian River and the AIWW. The extension of
the grid into this tributary will allow for the simulation of any discharge and tidal influences firom
the Hobe Sound and St. Lucie inlet approxima#ely sixteen miles upstream of the Jupiter Intet.
The second mode! boundary is lacated befvveen the State Highway A1A and the U.S. Highway
1 Bridge. The location of this model boundary includes the total freshwater discharge from the
surrounding tributaries of the Loxahatchee River watershed. The final madef baundary is
loca#ed at the mouth of the Loxahatchee River at Jupiter Inlet where freshwater inflow from the
�-- Loxahatchee River watershed discharges into the Atlantic Ocean.
�J .
Assumptions: The MIKE21 bathymetry and land surtaces extend to locations in the
Loxahatchee River and the Intercoastal Waterway where there is available existing data. The
' model extends to the best possible location using available data.
A review of the orthoimagery in the model extent shows existing levees along the majori#y of the
channels in the Loxahatchee and Indian River. These levees are not reflected in the data
retrieved from USGS. There was no existing survey data to properly refine the model surface,
so the levee loca#ions and heights were incorporated into fhe model surFace using best �
estimates �rom the orthoimagery and Gaogle street view.
. Input Parameters — Existing Condifions
The normal and extreme climatie periods of the existing site conditions of the Jupiter ]nlet were
modeled for the project. Three simulations were conducted for the existing conditions analysis:
• Simulation A— Normal Existing Conditions: Tide level time series at all open madel
boundaries during normal conditions.
• Simulation B— Existing Storm Surge: Extreme conditions with storm surge level #ime
series at all open model boundaries.
• Simulafiion C— Eycisting Storm Surge & Extreme Rainfall: Extreme conditions with storm

The period of record used for the existing conditions analysis of this study included a dry
weat�ter period of firvo weeks beginning on February 1, 20Q9. This period of record shaws
minimal rainfall to represent normal tide conditions in the project site. The tide signal rorrection
factors based from the NOAA gage at Miami Harbor during high and fow tides were applied to
the time series.
Freshwater Inflows: No active gages or relevant historical records were found that indicate the
magnitude of the daily freshwater inflows t4 the Jupiter lnlet. The freshwater inflows into the
�� inle# fihrough the Loxahatchee River from the surrot�nding tributaries were retrieved from a
previous study of the area by the South Florida Water Management District (�FWMD,20Q2).
Initial Simulations: An initial check on the model setup was performed using the NOAA tide
prediction gage at the U.S. Highway 1 intersection with the Loxahatchee River. The model was
setup using the default initial parameters and adjusted during subsequent model simula#ions.
The final parameters used for the preliminary modeling are presented in Table 5 below.

T�e initial simulations were setup with existing conditions at the open model boundaries. The

in[et between the A9A and U.S. Highway 1 Bridge. The NOAA tide prediction signals at the
Conch Bar and the South Jetty gage were applied at the other oPen boundaries. From the initial
results, the.application of a constant discharge boundary was discarded due to the sign�cant
influence of tidal inflow beyond the extent of the model. Russell et af. cites mixing ofi seawater
and freshwater up fo 10 river miles into the Loxahatchee River estuary., beyond the scvpe af the

Existing Conditions Simulations: Simulations of the si#e during existing conditions were
conducted to focus an water surface lev�ls during normat and e�ctreme rainfall events. This
methodc�logy provides a normal cvndition (Simula#ion A} far the purpose of comparison to the

simulations of the 25-year storm surge (Simulation B) in cambination with a 25-year rain#all
\� event (Simulation C). Simulation B includes only inputs af water surface elevation timeseries
during s#orm surge conditions. This represerrts tF�e simulatian of the site during storm surge
candition without freshwater discharge into the estuary during extreme rairrfall. Simulation C
represents the worst case scenario at the site during extreme rairrfafl and starm surge events.
Figure 8 of Appendix A presents a flowchart of the extreme events simulafions for the normal
site conditions.
Only estimates of average daily discharges in the Loxahatchee River were available during the
data collection period. In order to calculate peak water surtace elevatians at the critical pro3ect
areas, several tasks were employed to estimate peak discharges and water levels during
extrem� events. The main tasks and data sources are listed belaw:
• Historical daily discharge records for tributaries in the Loxahatchee River Watershed
(1980-2001), (Dent, 1997)
• USGS National Streamflow Statistics Equations for Estimating Peak Discharge at
Ungaged Locations.
• NOAA Slosh Mc�del Results for Hurricane Frances (2004) for the �outheast F[orida
Coastline �
• Combined Storm Tide Values for Various Return Periods for Palm Beach County —
Pro�le 1 (Florida State University)
• Extreme event return periods for Jupiter lnlet (Woodward Clyde, 1994)
• Rational method FAA equation to ca[culate watershed time flf concenfration
� The following is a brief description of each of the three simulations.
Simulation A— Existing Narmal Conditions
To generate the discharge for the model boundary and simufate the existing conditians between
the A'lA ar�d U.S. Highway '1 Bridge, a simulation was setup with tide signals at all open
boundary locatio�s. This achieved the simulation af the existing conditians at the project site
without using a discharge timeseries at the model opening.
Simulation B— Existing Storm Surc�e �
There are no historical observations of peak storm surge heights within the Jupiter Iniet model
boundaries. Several tasks were comp[eted to create the storm surge hydrographs to simulate
extreme rainfall and surge conditions for the 25-year event. The simulatian canducted using
these storm surge �evel inputs represent the site conditions only during storm surge, and not
coupled with an extreme rairrfall event. This simulation provides the tidal discharge during
storm surge conditions to be used for Simulation C. �

"25-year event surge height extrapolated from developing regression equation for Iisted storm �de heights.
`� A correction factor was used to extrapolate the observed storm surge hydrograph for the 5-10
year event to the listed peak water level height for the 25-yeac and 100-year event. This
hydrograph was applied at the model ocean boundary.
To create the storm surge timeseries for extreme events in the Indian River/ IntercoastaE
Waterway and the �oxahatchee River, correction f�ctors were applied to the western boundary
time series to account for the lag time and estimated surge reduction at these locations. The
same tim� and height correction used at high tiQe for the NQAA #ide prediction time series at the
two inland locations were applied in the storm surge time sQries to represen# the attenuation in
the surge tide characteristics once the tida! flow passes though the model boundary. Figure 9
in Appendix A presents the abserved storm surge hydrograph at the Bear Point gage used to
create the 25-year storm surge event a# the Jupiter 1n1et. Table A 1 also in Appendix A presents
the correction factors applied to the original storm surge timeseries from the N�AA SLOSH
mocEel at the Bear Point gage that was used for the extreme event simulations.
Simulation C— Existin�g Storm Surae and Extreme Rainfall
This final simu[ation combines freshwater discharge during extreme rainfiall conditions with the
tidal discharge calculated from Simulation B— Existing Storm Surge. There are no tidal flow
observations during extreme �vents within the model boundary on the.Loxahatchee River to
create a flux time series for the extreme conditions simulations. Tidal discharge at the U.S.

`� watershed during a 25-year extreme rair�fall event. Several tasks were completed to derive the
freshwater inflow to the estuary during an extreme rainfall event.
Final Data Summary Report AECOM
�� To evaluate extreme freshwater discharge values during several refurn periods, the USGS
� National Streamflow Stafistics Equations we�e u#iEized to extrapolate flow rates in the
Loxahatchee River for the different ex#reme events. ln order to caiibrate the equations, a
rainfall analysis was perforrned on his#orical recards to campare peak flows during the 25-year
event. The primary event for this analysis is the 25-year (10.15 in/24hr) event. No storm even#
matching this return period was available in the historical daiiy records. Therefore an additional
flow analysis was pertormed on the fallowing ret�rn periods presented by Woodward Clyde
(2004} in an �ffort to extrapolate the 25-year and 100-year freshwa#er discharge into Jupiter
inlet using #he 5 year and 10 year sform events. Table 7 presents the return periods for
extreme rair�fall events in the Jupiter lnlet area.

Since the initial simulations of the Jupiter lnlet model and several reports have cited tidal inflows
as the predominant driving fiorce during existing and extreme conditions (Russell et. al, 1984
reports freshwater inflow as 3% of the fiidal prism}, a simpEified procedure has been used to
estimate peak freshwater flows. The USGS National Streamflaw Statistics {NSS) pragram was
used to generate the hydrograph for the extreme event scenarios based on the input
parameters and weighted wi#h the observed historical discharges. Only the USGS Regression
Equations For Nafural Flow Conditions In Florida - Region A to estimate peak runoff were used
for the entire wa'tershed instead of dividing the Loxahatchee River Watershed into subbasins.
The SFINMD (2002) study presented historical stream#low records for several contributing
tributaries to the estuary. Flow ratios used in the study to derive the average total tiow from alE
contributing tribu#aries #o the estuary during the dry and wet season were analyzed for
application to develop the totaf flow during extreme �vents. The 5-year event analysis returned
sufficient information to develop a ca(ibration parameter far the USGS mfldel without having to
app[y the calculated flow ratios to each tributary to re-create missing flow data. Existing data
was available at all of #he tributaries to calculate the total peak flow rate in t�e estuary during the
5-ysar event. As a check, the f[ow ratios were applied to check the observecf 5-year event with
an observed 9 0-year event with missing data points tv ensure the calcula#eci flow rate from the
observed data was reasor�abfe. This flow analysis provided the corifidence to use the 5-year
,--- peak discharge as a calibration parameter for the USGS regression equations ta develop the
��� hydrograph far the 25-year return period.

�� MIKE 21 reports the calculated fiows as discharges, and the discharge outputs are given as
`� positive and negative values depending on the flow direction (i.e., incoming tide ar ou#going
tide). The discharge results preser�ted in this section were calculated as the total discharge
thraugh a transect taken from the left bank (i.e., project site shoreline) to rigF�t bank of the
channel (i.e., Jupiter Inlet Colorty shoreline) facing upstream of the flow. At each time step
discharge and the accumulated discharge are calculated for the two flow directions as well as
� for the net ftow {positive plus negative flow directions). Positive flow in the �ndian River
represents the ou#goin� tidal flow from the Indian River to the Loxahatchee River. Negative flow
represents tidal inf�ow from the Loxahatchee River up into the Indian River.
The discharge presented in this section represents the net cfischarge through the transect at
each time step. Average velocity is presented by retrieving a single point time series at several
points in channel at the project site. Several points were retrieved at the sife tfl show the
change in velocities near the bank. Figures 'I 1, 12, and 13 present the water surface fevel,
discharge, and velocity at sev�ral Iocations along the project site during the narmal conditions
simulation period. Figures 14, 15, and 16 portray the water surtace level, discharge, and speed
at several locations along the project site during the storm surge event simulation period, while
Figures 17, 18, and 19 shaw the water surtace level, discharge, and speed at several locations
along the project site during the storm surge and extreme rairifall event simulation period.
Figures 20, 21, and 22 in Appendix A depict the peak wat�r surtace levels during Normal and
Extreme Conditions across the Indian River at the project site location far existing conditions.
Table 9 presents a summary of the discharge, water surtace level, and mean speed at the
� project site during normal and extreme climatic conditians. Note the negative quantities for
` water surface elevations reference elevations below 0 ft NAVD88 while velocities correlate to
the flaw direction indicated by the + or - discharge value.

In general, Table 9 presents a prediction of the wa#er surtace elevation increasing under storm
surge conditions and reaches its highest elevation under ineoming tidal flows. fn additian, the
average vefocity is also predicted to be at a maximum for incoming tidal flows. -
Input Parameters — Proposed Conditions
The input parameters for modeling of the proposed conditions are the same as those used for
�-.� the existing conditions — Water Level Boundary, Freshwater Ir�flows, and Hydrodynamic
� Parameters. To analyze the propased bank stabilization for the proposed conditions, two
simula#ions were setup using similar parameter to Simulations B& C. This includes a 25-year
storm surge only scenario and a 25-year storm surge scenario combined with a 25-year storm
event discE�arge. �nly extreme climatic conditions were simulat�d because these have the
greatest influence on the design of the stahilization measures and provide #he most insight to
understanding the velocities and flows impacting the �roject site and its surrounding areas.
Each proposed simulation is represented with one typical layout anc! section for the north and
south area of the praject site. For each al#ernative, a 5 meter DEM (i.e., virtual representation of
the surveyed topography) was created according to the praposed sections and layout for the
restoration area. Each alternative ineludes three primary zones, with varying layout schemes.
The three primary zones inc[ude:
• Upland
- • Transitional
• I ntertidal
Figures 23, 24, and 25 pre�ent the DEM (5m) for the proposed conditions for Alternatives 'I , 2,
and 3. (These fgures also show the various typical sections used in the design development;
however, only the modeling results for A-A', C-C', E-E', and F-�' are presented in this report.)
Resu/ts — Proposed Condifions

� existing channel. ln order to best reflect the praposed shoreline, cross sections A-A', E-E' and
�,_� F-F' were chosen to reflect the typical features of the proposed channel.
Similar figures showing the output results - water surtace level, discharge, and velocity - for the
propased modeling simulations were developed. However, the proposed modeling results for
water surFace elevation and discharge were not significantly different from the existing
conditions, but velocities showed some variance. Therefore, tables are presented below to
pravide a better comparison for evaluating the simula#ion results. .

Maximum water su�face e[evation in the tidal zone at the three typical sections for each
alternative remains consis#ent thraugh the entire layout. As expected, the slope #reatment for
each a[ternative does nat affect the peak water surface level since it is driven by the storm
surge and storm discharge. Higher maximum water leve[s in section E-E' and F-F' compared to
the northern sections are likely due to gradual attenuation in the tidal surge level as the tide
propagates upstream into the Intercoastal waterway. An average maximum water surFace level
of 2 meters throughout t�e entire restoration site during the extreme events is predicted in all of
the intertidal zones. The transitional zones for each altemative are only inundated at certain
sections in each a{ternative. It should be pointed out that the maximum water surtace elevation
presented in Table 10 oniy represents the water level resulting from tides, storm surges and
runoffs, and does not include the local wave runup on the revetment banks.

Table 11 �elow presents the mean and maximum velocities for the proposed conditior�s at fhe
'� upland, transition, and intertidal zone far Sections A-A', E-E', and F-F' during the two extreme

Note: Zero current speeds mean that the zone is not inundated during the extreme event and remains dry.
Maximum velacities reach 1 m/s (3.3 ft/s} �n the intertidal zone during both 25-year s#arm
scenarias. Stone toe slope protection is required to protect the fidal planti�gs during extreme
climatic events ftom the current in the [ntercoastal Waterway.
The mean and max speed at section A-A' for the three alternatives remains consistent. The
�. same layout at this section is planned for each alternative.
The results of the simulation predict some differences in mean and max speed throughout the
three alternatives af section E-E' during the extreme climatic events. Higher velocities occur in
the tidal and transition zones at Section E-E' in Alternative 2. Differences in vefocity may occur
due fo the shorter intertida! zone between the #ransition zone and the lntercoasta! Waterway.
The average s�ope from the transition zone to the invert of the intertidal zone is consistently
steeper than that of AI#ernatives '[ and 3. ln addition,.this zone is currently represenfed by one
to two mode! grid cells, which may be coarse #a accura#ely reflect the actual flow canditions at
this location. �
At section F=F', differences in maximum speed between the alternative treatments are noted in
aiternative 1. Alternative 2 and 3 share a similar transitional slape between the upland and
transition zones. Section F-F' for altemative 1 is treatecf with a steeper slope, possibly causing
the transitional and intertidal zones to experience higher maximum velocities at the peak surg�
during extreme events.
Conclusions
Results from this phase of the analysis show maximum velocities of 3.3 ft/s in the intertidal zone
throughout the entire project shoreline for each altemative during both extreme event scenarios.
,� The combinafion of a 25-year storm surge and a 25-year rainfa[I event produces only slightly
nigher veiocities and a slightly higher peak water surFace elevation than a scenario with only
storm surge. Also a slightly higher maximum water surFac� level at the shoreline near the
cor�fluence of the Intertidal waterway and the Loxahatchee River is predicted. This difference

may be explained from the large surge inflow from the Jupiter Inlet up into the lntercoastaf
� waterway during the extreme events.
As a result, it is predicted that the three altematives will not signif9cantly impact the existing �
channel con�itions. it is recommended that under Phase 2(final d�sign) of the prvject,
surveying of the Jupiter Inlet Colony shoreline be conducted to provide a more accurate DEM
that wiq allow for a more confident anaiysis.
In addition, it is recommended that the madel grid cell� be made smaUer than 25 square meters
for the Phase 2 analysis of the project to allow for rnore detailed conclusions about the wave
dynamics in the variovs zones along the shorelinc. For this preliminary modeiing effort, the
model points used for the time ser�es extraction at the intertidal, transition, and upland zones
were chosen at elevations representative of that particular zone. Since the transitional zone
averages 2.5 m{8.2 ft) in width and s��eral areas of the intertidal zone average less than 5 m
(16.4 fE) in width, ce[Is with the closest elevations to the original section were selected #or
analysis. Developing a refined model with smalfer grid cells will allow for a more ac�urate
analysis.

�� 7.0 Cultural and Historical Resources Survey Review
�__1
For a project such as #he Jupiter inlet Lighthouse Shareline Res#oration Project, a cultural
resource survey is required as an integral part af the environmental assessment and impact
evaluation by the National Environmental Policy Act (NEPA} of 1970 {PL 91-9t30). The feld
investigation reported below cons#itutes a Stage I survey consisting of: 1} literature, archive and
site file research to identify any known or potentia[ cultural resources (historical, architectural, or
archaeolagicai) not already icientified by inclusion on the State or National Register of Historic
� Places and 2) a surtace inspection af #he proposed project corridor with subsurFace testing
sufficient to determine the presence or absence of prehistoric ar historic materials. The
investigation was carried out by a BLM contractor overseen by John Sullivan, BLM Archeologist.
Subsurface testing included 12 judgmer�tapy shovel tests (ST-31 to ST-42) that were spec�cally
dug to determine whether the sediments on the bank are natural ar redepQSited (see Figure 26
in Appendix A). Testing was conducted from October 22 to October 27, 2009 located along the
western Jupifer Sound shoreline on an existing ,north-south transect cut by surveyors. The
shoreline tests began at a southern perimeter fence line {the fence is on an east-west
alignmen#). Testi�g was terminated on the north-end at Gomez Road. Shovel tests were
generally placed within the area where the edge of the shoreline begins to as far as four meters
west of the shoreline edge. Each shovel test measured 50 cm in diameter and was excavated to
a'! 00 cm depth or just below the wa#er table.
Two shovel tests were positive (ST-31 and ST-32) for prehistoric cultural material that included
� oyster shell and faunal ban�. Shovel test {ST-31), was placed at the south-end of the transec#
where an existing east-west perimeter fence line intersects with the Eastem shoreline. Shovel
test #31 was the only positive shove[ test that contained cuitural material firom an intact context.
Shovel test #32 yielded cultural material {oyster), but this came from a redeposited midden
eontext. Statigraphy of the positive test for ST-3'1 (FS-20) is as follows:
• 0-30 cmbs: Redeposited gray sand with moderate amounts of oyster/sparse fiaunal bone
• 30-40 cmbs: Redepvsited very dark gray sand (sterile)
• 40-55 cmbs: Intact gray sand with some ayster
• 55-85 cmbs: Light gray sand with some oyster
• 85-100 cmbs: Very light gray sand (sterile)
Shovel test #32 (FS�2� ) was placed 40 meters north of ST-31. Oyster shell was found at 0-25
cmbs within a redeposited midden soi[ context. Below this horizon was redeposited (dredged)
�very Eight gray sand (25-100 cmbs).
The remaining shovel tests (ST-33-42) uncovered redeposited (dredged) sediments. They are
characterized as very [ight gray/white sand, which had a powdery texture and ir�clusions of
some gray clay particles/maderate amounts of marine shell (represen#ing several species af
bivalves, including oyster). Only ST-38, ST-39 and ST-49 had intact natural sediments located
withi� the basal zones of s#erile loamy gray sand. None o# these rtatural levels included cultural
materials. �
��� A profile was drawn of exposed eroding bank sediments where organic and possible midden
� components had been obsenred (see Figures 27, 28 and 29 in Appendix A). The profile
measured one meter wide by 3.87 meters deep. It was determined that all horizons within the
profile had been redeposit�d by dredging activities. The dark organEC horizon was nat midden or

a eultural horizon but rat�er a band of clay. Soil samples were collected of each context within
��� the profifed area.
In conclusian, most ofi the parcel's eastern shareline from Gomez Road southward is composed
of dredged sediments except for the area south of �T-32, where intact soifs and a prehistoric
she[I midden occur. The western extent of these dredgec� sediments is not known. As of late
December 2009, the cultural resource investigations in the prole�t area were not yet camplete.
In earty January 2010, the investigations are expected to eontinue. The future work will consist
of taking soil core samples at a midden site discovered during the Rhase I survey a# the south
end of the projec# area. The midden is located about 2 meters be[ow ground, and 30-60 meters
from the fence.
In the next phase of the project (final design and permitting}, cultural resource findings will be
applied to determine appropriate mitigation recorrmmendations for the alternative�. However, it
has been recommended that the proposed bank stabilization consider an alternative that does
not include excavation, but daes inc[ude adding fill sediments to sensi#ive areas, south of ST -
31.. Newly placed ma#erials would mantle exposed soils, and thus impacts frorn placement of
' s#abi[izing materials and/or methods could be directed towards the fifl mantle. Stabilization
methodology for the bank a[ong the area northward wi![ have more flexibili#y in regard to cuftural
resources.

SalandWater along the Loxahatchee River tintracoastal) that
Coeservation you were
Oistridaffice concerned with. It is my opinion that the soils are
predominantly natural in Lot ].7, and do not need to be
702e20�'Place truncated or reshaped. There is some filling and major
SuiteA disturbance in Lot 18 along the edge of 17, where the dwellings
Vero Beach, Florida are, but borin s across the fence in Lot 17 revealed clean fine
32980-5360 g
sand, with a mostly natural succession of chromas, to 60 inches
(772) 562-1923 +. This was true on the intracoastal side of lat 17 as well.
770-5005 The topography and e�evatians resemble that of the park which
770-593d you co-own in Lot 15 and historic photos {i.e. 3953) show a
563-4926(fax) natural surface in iot 17 similar to that of 15.
• The soils are primarily excessive3.y drained Quartzipsamments
and most closeJ.y resemble St. Lucie (with some minor co7.or
variations). The eroded dune is chroma 3 in nature and
resembles an Astatula, but the main point is that most of ].at
Z7 is fine sand with no waCer table within 80 inches. These are
marine and aeolian deposits and naturaJ.J.y exist as nearly level
to strongly sloping dune-like ridges. The soil surfaces have
seen some heavy equipment and there are some minor disturbances
!� possible due to tractor tires and leveling, but nothing that
` will alter the .interpretations, or management of these soils.
If you carefully read the map unit description, it says that
some of the ridges were cut down and same material was spread
over lower areas. This was af a minor extent and should not be
confused with fill from constructian ox other unnatural
sources, being brought in.
This area is basicaily mapped cozrectly and we did see a
low and narrow manmade berm alonq the southern edqe of 17 for
instance and the Brazilian peppes is so thick that there may be
similar azeas that we could not see. Lat 17 is grimarily find
sand with very few sheli fragments and as you get claser ta �he
intracoastal, the soils slope down and you find a natural,
appearing backwater area, or f2ood zone where the sails have a
water table at the same elevation as the river, or rougttly 4 to
4�a feet below grade. We did take UTM coordinates of our
borings and brief color descriptions to 60 inches it yau need
thase. I am consulting with the Disfirict Conservationist and
area enqineers to see if we.can help you any further. The
erosion is so severe on the dune, I feel you will have to
discuss its control with an engineer and plantings won't be
enough.
One t�ing you may find usefu]. in your Florida work is a U of

Attention: Mr. David Lidberg, P.S.M.
Subject: Report Of Subsurjace Exploration
$horeline Stabilization Project
US Coast Guard Lake Worth Inlet Housing
Jupiter, Florida
Mr. Lidberg:
Pursuant to your verbal authorization to proceed, Dunkelberger Engineering &"I'esting, Inc.
(Dunkelberger) has completed subsurface exploration to define the nature, sequencing and condition
of the soil profile components that exist along the proposed shoreline stabilization project of the US
Coast Guard Lake Worth Inlet Housing site in .iupiter, Florida. This letter describes the geotechnical
work that was performed and provides the results of the subsurface exploration.
On November 10, 2009, two Standard Penetration Test (SPT) borings {designated Borings TB-1 and
TB-2) were drilled at the locations shown on Sheet ]. "I�he engineering borings were f eld staked
along the area of the proposed shore(ine stabilization by Lidberg Lancl Surveyin�, Inc. Because of
scattered construction and demolition debris mainly composed of concrete rubble, poles and slabs,
Borings TB-1 and TB-2 were offset south (i.e. waterside} of the staked locations by distances of 15
and 12 feet, respectively. Photographs of the project area, boring locations and our exploratory work
are attached in the Appendix.
The SPT borings were accomplished with a CME 55 drilling rig mounted on the deck of� a barge.
Three-inch diameter steel casing was installed in the boreholes as needed to maintain drilling fluid
circulation. Samples of the in-place materials were recovered at frequent vertical intervals using a
standard split-spoon driven tivith a 140-pound hammer freely falling 30 inches (the Standard
Penetration Test [SPT] after ASTM D 1586}.
Samples recovered from the borings were placed in moisture-proof containers and returned to the
laboratory where they were visually examined and classified using Unified Soil Classification
System (ASTM D 2487) nomenclature. Subsurface profiles containing records of the SPTs are also
presented on Sheet 1.
The water depth at the boring locatians was approximately 5 feet at the time of the drilling. Soils
found in Boring TB-1 consist of loose to medium dense clean sands that extend to roughly 6.5
feet below the mudline. The clean sands are underlain by loose to medium dense sands with
sorne sand-sized shell fragments and cemented sand and shell lenses that continue to the
maximum depth of exploration of 31 feet (measured from the deck of the barge). Subsurface
materials found in Boring TB-2 were composed of very loose to loose clean sands that begin at
the mudline and extend to 31 feet.

Design of the proposed bank stabilization praject shouid consider the presence of the existing
concrete nabble, poles and slabs that occupy the area to be improved. Further, the geometry af the
slope 6oth above and below the area to be stabilized should be considered in the design.
This report was prepazed for Lidberg Land Surveying, Inc. to provide subsurface data associated with
the proposed shoreline stabilization project for the US Caast Guard Lake Worth Inlet Housing site in
Jupiter, Florida. The factual data. presented herein was obtained using standard geotechnical
exploration and labaratory testzng methods. No other warranties are expressed or implied.
Dunkelberger Engineering & Testing, Inc. appreciates the opportunity to assist you on this project.
We trust that the information provided in the report is clear and understandable. ShouId it require
any clarification or ampli�cation, however, please contact us.

Re: Bluff Stabilization Recommendations
Dear Mr. Dawson:
I am providing recommendations regarding the proposed stabilizarion for the bluff on the shore of the
Indian River. The bluff is associated with prehistoric archaeological site 8PB34. 'The prehistoric and
historic cultural deposits are a contributing comrponent of a potential National Register historic district
encompassing the Jupiter Inlet Lighthouse. '
Because of the site's significance Section lOb (National Preservation Act) requires that any proposed
development or ground-disturbing activities considcr potential adverse impacts to the site. An archival
review of rnaps and other documents suggests that the heavily eroded shore had been previously altered
and subjectcd to some placement of fill. However, cultural deposits occur within the proposed projcct
area and portions of 8PB34 have associated human remains.
It is recommended that plans to stabilize the shore and banks rninirnize impacts to the site by �voiding
excavarions that create a slope sincc such excavations may affect cultural deposits. Other options such as
introducing fill (but not foreign materials such as boulders, concrete, or rip-rap) or fill placed behind
terraced bulkheads should be considered.
Sincerely,
��r��� �..�.-

�� Summary
This report is provided as a summary of archaeolagical testing of the shoreline adjacent to
Jupiter Saund (Intercoastal Waterway) located on BLM property in Jupiter, Florida. The parcel is
located in Section 31, Township 42E, Range �OE. These tests were specifically dug to determine
whether the sediments on the bank are natural or redeposited. Testing was conducted from
October 22 to October 27, 2009.
Twelve judgmentally shovel tests (ST-31 to ST-42) were excavated along the western Jupiter
Sound shoreline on an existing north-south transect cut by surveyors. The shoreline tests began
at a southern perimeter fence line (the fence is on an east-west alignment). Testing was
terminated on the north-end at Gomez Road. Shovel tests were generally placed within the azea.
where the edge of the shoreline begins to as far as four meters west of the shoreline edge. Each
shovel test measured SO cm in diameter and was excavated to a 100 cm depth ar just below the
water table.
Two shovel tests were positive (ST-31 and ST-32) for prehistoric cultural matezial that included
oyster shell and faunal bone. Shovel test (ST-31), was placed at the south-end of the transect,
where an existing east-west perimeter fence line intersects with the eastem shoreline. Shovel test
#31 was the only positive shovel test that contained cultural material from an intact context.
Shovel test #32 yielded cultural material (oyster), but this came frozn a redeposited midden
context A summary of the positive test is provided below:
� Stratigraphy o£ ST-31 (FS-20) is as follows:
4-30 cmbs: Redeposited gray sand with moderate amounts of oyster/sparse faunal bane
30-40 cmbs: Redeposited very dark gray sand (sterile)
40-55 cmbs: Intact gray sand with some oyster
55-85 cmbs: Light gray sand with some oyster
85-100 cmbs: Very light gra,y sand {sterile)
� Shovel test #32 (FS-21) was placed 40 zn�etezs north o� ST-31. Oyster shell was found at 0-25
cmbs within a redeposited midden soil context. Below this horizon was redeposited {dredged)
very light gray sand (25-100 cmbs).
The remaining shovel tests (ST-33-42) uncovered redeposited (dredged) sediments. They are
characterized as very light gray/white sand, which had a powdery texture and inclusions of some
gray clay particles/moderate amounts of ma.rine snell (representing several species of bivalves,
including oyster). Only ST-38, ST-39 and ST-41 had intact natural sediments located within the
basal zones of sterile Ioamy gray sand. None of these natural Ievels included culfural materials.
A profile was drawn of exposed eroding bank sediments where organic and possible midden
components had been obsezved (see Figures 2,3,4). The profile measured one meter wide by 3.87
meters deep. It was detenmined that all horizons within the profile had been redeposited by
dredging activities. The dark organic horizon was not midden or a cultural harizon but rather a
band of clay. Soil samples were callected of each context within the profiled area.

�� i
In conclusion, rnast of the parcel's eastern shoreline frorn Gomez Road southward is cornposed
of dredged sediments except for the area south of ST-32, where intact soils and a prehistoric
shell midden occurs. The western extent af these dredged sediments is not known.
Recommendations
Archaeological testing indicates the shoreline north of ST-32 is largely dredged redeposited
sediments. Areas south of ST-32 are problematic, since it appears that erosion has likely
encroached into natural sediments and cultural deposits.
Proposed bank stahilization should consider adding fill sediments to sensitive areas, sou�h of ST-
31. These newly placed materials would mantle exposed soils, and thus impacts from placement
of sfabilizing materials and/or methods could be directed towards the filI mantle. Stabilization
methodology far the bank along the area northward will have more flexibilify in regaz�d to
cultural resources.
