Page 6 of 34
Erosion District Meeting Tuesday, October 21, 2025 6:01 PM
inlet and federal features, including the depth, width, and jetties. He explained that the historical approach
to nourishment involved the Army Corps of Engineers funding 78% of the project, while St. Lucie County
managed the remaining portion. The port has been collaborating with the Army Corps of Engineers to
establish a new plan for the beach and the T-grid structures. He discussed the long-term relationship with
the Army Corps of Engineers and the need for their involvement to manage costs and impacts from the
federal inlet. He mentioned submitting a project feasibility study to the Assistant Secretary of the Army's
office and receiving conditional authorization in 2022. The project has been under review for the past four
years, with responses to conditions submitted and currently being reviewed. The goal is to get approval
from the Army Corps of Engineers and the ASA office by the end of the year to move the project forward.
With the reward of the T groins in reducing wave energy and retaining sand for longer periods, the aim is
for a four-year sand placement schedule. The strategic placement of sand helps feed beaches to the south,
addressing the sand deficit and preventing further erosion. The County manages only an estimated seven
miles of beach, with neighboring counties managing more coastline, and it is important to preserve
relationships. The federal shore protection project is expected to commence in February next year,
providing long-term solutions. Mr. Revord discussed the most recent beach re -nourishment project, which
involved truck hauling. This decision was made by the Board in the spring and contributed to the beach
reaching its current condition. The project included full reimbursement from the state, positioning the
County for future spot treatments to preserve the park.
6. MOTION TO ADJOURN
There being no further business to be brought before the Board, the meeting was adjourned at 6:09 PM.
Please note: Final minutes are recorded in the official minute books that are filed with the Clerk of the

Port, Inlet & Beaches
Work Authorization No. 01 (Coastal Tech, Inc.) - St. Lucie County, Florida, Coastal
Storm Risk Management (CSRM) Project: 2025/2026 Pre, During, and Immediate
Post Construction Support Services
St. Lucie County pursued the federalization of its southern beaches in the early 2000's. The need to formally
address erosion was championed by local interests in response to specific storm impacts. Damages from these
storm events resulted in a formal federal request to the U.S. Army Corps of Engineers (USACE) for federal
assistance in maintaining storm damage protection along St. Lucie County's southern shoreline. While
pursuing future federal cooperation, a one-time (locally funded) beach project was approved and completed
(within the proposed federal beach project area) in 2013 to address persistent erosion. Eventually, a
feasibility study was completed for the project area (southern 3.4 miles of St. Lucie County's Atlantic
shoreline) and Congress authorized the construction of the St. Lucie County, Florida, Coastal Storm Risk
Management (CSRM) Project. Federal appropriations were subsequently petitioned for and approved by
Congress for this CSRM project, and a Municipal Services Taxing Unit (MSTU) was created by the BOCC
(adjacent to the project area) to help fund the balance of future federal construction. In 2020, St. Lucie
County's BOCC entered into a 50-year Project Partnership Agreement (PPA) with the USACE for the newly
authorized federal beach project. The design, permitting, and bidding of the federal beach project were all
completed in 2021, and initial project construction was completed in May of 2022. Subsequently, the passing
of Hurricanes Ian and Nicole (after initial project completion) caused significant impacts to the project area
which led St. Lucie County to petition the USACE for rehabilitation of the project area.
A vital component of this upcoming 2025/2026 federal beach project is environmental protection. As such,
both the County and the USACE (as co-permittee's, Agenda Item 2020-50865) are responsible for adhering to
all environmental conditions found within our active state permit (Joint Coastal Permit 0154626-001-JC) from
the Florida Department of Environmental Protection (FDEP). Permit compliance conditions include, but are
not limited to, pre & post -construction physical monitoring (surveys), post -construction biological monitoring
(sea turtles, shore birds, and nearshore hardbottom), and a variety of other project reporting elements
needed to track impacts (if any) associated with the upcoming federal beach rehabilitation project. The tasks
identified in Work Authorization No. 01 (Coastal Tech, Inc.) - 2025/2026 Pre, During, and Immediate Post
Construction Support Services - fulfill our permit obligations for pre -construction, during construction, and
immediate post -construction monitoring of the upcoming beach project and have been reviewed/pre-
approved by the FDEP for cost -sharing under several FDEP Grants: FDEP Grants 20SL3 (Fund # 194486; 43.49%
Page 18 of 34
state, 56.51% local) and 23SL1 (Fund # 184240; 100% state). Local funding for the grants was previously
secured from the South Hutchinson Island (SHI) Municipal Services Taxing Unit (MSTU) - FUND 194. The
proposed 2025/26 federal beach project is a 100% federal rehabilitation effort that is a result of impacts
associated with the passing of Hurricane Nicole. Construction will be performed at 100% federal expenditure
and both construction administration and pre/during/immediate post -construction physical and biological
monitoring efforts are the responsibility of the non-federal sponsor.

EXHIBIT "A"
SCOPE OF SERVICES
Work Authorization 1
Introduction: Initial construction of the South County Beach & Dune Restoration Project (Project)
was completed in April 2013 without federal participation and included placement of 635,164 cubic
yards of sand along 17,739 feet of shoreline from Florida Department of Environmental Protection
(FDEP) Reference Monuments R-98 near the County's Normandy Beach Park to about 1,000 ft south
of R-115 at the southern limits of St. Lucie County. The initial nourishment of the federally authorized
St. Lucie County, Florida Coastal Storm Risk Management Project (CSRMP) was completed in May
2022 and placed about 387,165 cubic yards of sand from R-98 to the southern limits of St. Lucie
County. Post -Construction Physical Monitoring of the Project has revealed the need for re -
nourishment of Project beaches — after significant erosion incurred from Hurricanes Ian and Nicole.
Construction of the Project is expected to begin at the completion of the current sea turtle nesting
season and priorto the upcoming sea turtle nesting season (November 30, 2025 to May 1, 2026). The
COUNTY shall notify COASTAL TECH of the expected start of construction at least 90 days prior to
the start — to facilitate the timing, scheduling and performance of services under this Work
Authorization.
This Scope of Work is to provide support for construction phase services and permit compliance for
the proposed USACE CSRMP prior to ("Pre") construction, during construction, and immediately
after ("Post") construction. The Work is proposed to be performed by COASTAL TECH with support

2 - During Construction
Task 2- Engineering Services: Duri ng construction, the USACE and COUNTY will administer the
Construction Contract with assistance from COASTAL TECH; the USACE and COUNTY will
provide all communications to the Contractor relative to Project construction. In general,
COASTAL TECH will directly observe and spot-check the Contractor's work for compliance with
the FDEP permit, identify discrepancies with the permit, and report any significant discrepancies
to the USACE and COUNTY. During construction, COASTAL TECH will:
(1) prior to the Contractor's mobilization to the site, document conditions within and
adjacent to the Project fill area to be used by the Contractor including truck routes,
access/staging areas, and existing dune overwalks and beach access stairs;
(2) Duringthe Contractor's placement and grading of sand fill (estimated at up to 70 days),
we will:
• conduct site visits weekly (up to 30 site visits) at the beach fill area to observe the
work- includingweekly Partnering meetings with COUNTY, USACE & Contractor;
• perform an additional up to eight (8) site visits or prepare for and attend public
meetings as requested by the COUNTY; and
• provide a written summary of the Contractor's progress on a weekly basis.
During the site visits, our observations will include:
• photo documentation of observed construction activities which will be
compiled in a daily report;
• confirm the Contractor maintains Record Drawings and documents - as
required by the FDEP permit;
• the layout of the work by the Contractor,
• the details of the work including final grading and dressing of placed fill,
• the tilling of the beach by the Contractor following completion of each fill
acceptance section or the placement of fill;
• the Contractor's work area and measures to provide for public safety;
• turbidity monitoring and reporting by the Contractor including the
Contractor's Testing Certificate; submit the required turbidity reports to
FDEP (per Specific Condition 37 of the FDEP permit);

areas and trucking routes.
(9) Review the Contractor's proposed Maintenance of Traffic Plan.
(10) Provide a final certification to the COUNTY and FDEP upon the Contractor's successful
completion of the work.
The FDEP permit requires daily shorebird, marine turtle, water quality, and sand quality monitoring
and reporting. It is our understanding that USACE, as the project construction administrator, will
conduct all such environmental monitoring through construction completion. We will coordinate
with the USACE and Contractor to track and review environmental monitoring efforts to verify that
construction activities and report submittals remain compliant with specific conditions of the
permit. Additionally, we will request copies of the Contractor's pre- and post -fill placement payment
surveys and review the data for consistency with the Project design and FDEP permit.
3 —Post Construction Monitoring
Task 3a — Physical Monitoring: COASTAL TECH will provide physical monitoring services for
immediate post -construction monitoring of the Project - consistent with the Physical Monitoring
Plan (PMP) dated June 12, 2012 as required by the FDEP Permit. It is our understanding that the
USACE will provide the post -construction topographic and bathymetric surveys of the beach and
offshore borrow area as required by the Physical Monitoring Plan and the BOEM agreement.
Consistent with the PMP, COASTAL TECH will:
(1) Prepare 81/2" by 11" plots of the new surveyed profiles with (a) the pre -construction
profiles provided by the USACE, and (b) the USACE construction template as provided
by the USACE;
(2) compute and assess volumes and shoreline changes based upon the new profile
surveys; and
(3) provide a letter report summarizing results of the above with digital (PDF) format.
Task 3b — Biological Monitoring — Sea Turtles: The Technical Specifications require the
Contractor to perform seaturtle monitoring prior to Construction completion. COASTAL TECH,
via sub -contract with EAI, will provide FDEP permit required biological services for post -
construction sea turtle monitoring for the Project. All sea turtle monitoring and related activities
will be performed under FWC Marine Turtle Permit #010 issued by FWC to EAI Co -President and
Director of Operations, Niki Desjardin. All persons engaged in monitoring performed by EAI for
St. Lucie County will be listed on the permit. All data will be subject to rigorous QA/QC protocols
and stored in EAI's project specific database. Daily nesting surveys will be charged at a per
survey rate. EAI will perform the following sub -tasks:
Task 3b.1 — Post -construction Nesting Surveys: Per SPBO Condition All, Table 18, after
construction is completed, EAI will conduct daily morning sea turtle nesting surveys of the
Project Area from February 25 to April 30, 2026 (Dates FDEP Permit allows for construction)
and from May 1, 2026 through November 11, 2026 (Dates after FDEP Permit allows for
construction) or until fifteen (15) days without a nest in the Project Area, whichever is earlier.
If there is a fifteen -day period where no nests are laid in the Project Area, EAI will request a
waiver from the USFWS and FWC to discontinue daily monitoring. If permission is granted,
EAI will then perform surveys three days per week to monitor marked nests until a fate can
be determined.
Page 3 of 8
November 4, 2025
Page 27 of 34
St. Lucie County Work Authorization I
Pre, During, & Immediate Post Construction Support Scope of Services
Surveys will commence within 30 minutes of sunrise. Monitoring will be performed by EAI
staff using All Terrain Vehicles (ATVs). All emergences (turtle crawls) apparent from the
previous night will be interpreted to determine which species of turtle came ashore and
whether or not it nested. Crawls will be denoted as being above or below the previous high
tide line. The approximate geographic location of each crawl will be determined by GPS (sub -
meter accuracy). In addition to segregating crawls into nesting and non -nesting emergences
(false crawls), each false crawl will be assigned to one of the following categories denoting
the stage at which the nesting attempt was abandoned: no digging, abandoned body pit, or
abandoned egg cavity. Any obstacles encountered by turtles during their crawls will be
documented.
During the course of daily monitoring, any evidence of hatchling misorientation or
disorientation from either marked or unmarked nests will be documented using FWC's
electronic Marine Turtle Hatchling Disorientation Incident Report Form. Based on track
evaluations, an estimate of the number of hatchlings disoriented will be recorded and light
sources potentially responsible for the disorientation identified. Information concerning
each incident will be forwarded by email to St. Lucie County so appropriate remedial action
may be taken. Information from disorientation events is also used by Code Enforcement and
the Sea Turtle Working Group to improve lighting conditions on the beach.
A requirement of FWC sea turtle permit holders conducting nesting surveys is to respond to
the stranding of sick, injured, and dead sea turtles within their survey area. These animals
are examined, and if alive, transported to state approved care facilities. A standard Sea Turtle
Stranding and Salvage data form will be completed and submitted for each stranded animal
encountered by EAI. This information will be transmitted to FWC in accordance with
established guidelines.
Task 3b.2 — Nest Marking and Monitoring: Per FDEP Specific Condition 31, once the
construction -phase nest protection program has been completed, a representative sample
of sea turtle nests in the Project Area will be left in place and marked for the purpose of
determining nest fate and reproductive success. Nests will be marked using a series of
stakes and surveyor's tape. These nests will be monitored throughout their incubation period
to determine nest fate (e.g., hatched, washed out, depredated, vandalized, etc.). After an
appropriate incubation period, and in accordance with FWC guidelines, nests will be
excavated to determine reproductive success. Two measures of reproductive success will
be calculated: hatching success (the percentage of eggs in the nestthat hatch) and emerging
success (the percentage of eggs in the nest that produce hatchlings which successfully
escape from the nest). Nest marking will be charged at a per nest rate.
Task 3b.3 —Weekly Escarpment Monitoring: Per FDEP Specific Condition 30, EAI will perform
escarpment (scarp) monitoring on a weekly basis commencing March 1, 2022 or immediately
after completion of the sand placement project and continuing through October 31, 2022.
Scarp monitoring will not take place during construction. In accordance with FWC protocol,
scarps will be functionally defined as an abrupt change in beach slope (greater than 45) that
is at least 18 inches in height and persists for a distance of 100 feet or more. The location of
both the northern and southern terminus of each scarp will be recorded by GPS and average
scarp height assigned to one of three categories (0 to 2 feet, 2 to 4 feet, and 4 feet or higher).
Page 4 of 8
November 4, 2025
Page 28 of 34
St. Lucie County Work Authorization I
Pre, During, & Immediate Post Construction Support Scope of Services
Additionally, the maximum height of each scarp will be measured. The location, approximate
length, height category, and maximum height will be presented in tabular and/or graphic
format for reporting purposes. EAI will notify COASTAL TECH and the COUNTY of any
persistent scarps that may interfere with sea turtle nesting. COASTAL TECH shall notify FDEP
of the presence of those scarps and for coordinating any mechanical knockdowns by the
COUNTY if required. Scarp monitoring will be charged at a per survey rate.
Task 3b.4 — Post -Construction Nesting Shorebird Monitoring and Protection: Per FDEP
Specific Condition 15 & 16, once construction has been completed, weekly surveys for
nesting shorebirds within the project area will be conducted by EAI through August 31, 2026.
EAI will report all breeding activity to the Florida Shorebird Database within one week of data
collection. Shorebird monitoring activities will comply with all protocols outlined on the
Florida Shorebird Database website. Nesting shorebird surveys will be charged at a per
survey rate.
Task 3b.5 — Coastal Lighting Survey & Management: Per FDEP Specific Condition 33, EAI will
perform two nighttime beachfront lighting surveys of the Project Area (one between May 1
and May 15 and one between July 15 and August 1). During each survey, all lights visible from
the beach will be identified. All facilities with visible lights will be evaluated for compliance
with local lighting regulations. Photos (long exposure, without flash) will also be taken of all
lights visible from the beach. A full report including photographs and GPS locations of lights,
alongwith a unique site evaluation form for each facility/property evaluated will be furnished.
In addition, each non -compliant light will be listed in tabular format (with associated
metadata such as property address, latitude and longitude of the light, fixture type, lamp
intensity) and recommendations will be provided for resolving lighting problems. In support
of Specific Condition 33, EAI will attend one meeting with St. Lucie County and appropriate
agency personnel to discuss results of the lighting inspections and address any sea turtle
disorientation events that occurred. Lighting surveys will be charged at a per survey rate and
the lighting meeting will be charged at a per meeting rate.
Task 3b.6 — In -Water Sea Turtle: COASTAL TECH, via sub -contract with EAI, will provide four
(4) quarterly biological in -water turtle surveys starting with the immediate post -construction
monitoring event for a total of one year of monitoring. EAI will perform each of the in -water
surveys of nearshore hardbottom to assess project effects on marine turtles utilizing habitats
adjacent to the project area.
EAI will use a boat equipped with an elevated platform capable of holding two observers to
traverse four (4) shore -parallel transects at a constant speed. Two of the transects will be
Located just offshore of the project area and two will be located north of the project area.
Transect endpoints will be identical to the southern four of the five transects used for in -
water surveys conducted by EAI from December 2008 through August 2009.
As the boat traverses each transect, one observer will look forward and to the port side and
the other forward and to the starboard side. Each transect will be traversed two times.
Surveys will only be conducted during periods of calm seas (2.5 feet or less), with no
whitecaps or breaking waves, other than wave break on the beach. Monitoring of all four
transects will be conducted on the same day.

November 4, 2025
Page 29 of 34
St. Lucie County Work Authorization I
Pre, During, & Immediate Post Construction Support Scope of Services
When a turtle is sighted, the position of the vessel at the time of the sighting will be recorded
by GPS. The position of the turtle will be mapped based on the position of the boat and the
observer's estimate of the distance and bearing to the turtle. In addition to recording the
position of the turtle, the observer will also record the time the turtle was first observed, the
species, its relative size, and whether it was at the surface or submerged. EAI will provide a
summary report of the methods and results of the surveys.
A letter report summarizing the data collected during each sampling event will be provided
to the COUNTY within six weeks of the survey. The report will include the number of turtles
per transect and pass by species and location in the water column with a map of the
transects and turtle locations. Turtle sightings will be converted to densities to allow
comparisons among transects. An annual report compiling all data collected will be
provided within 60 days of the final field event. The final report will document all sea turtles
recorded throughout the project period and include a comparison to previous surveys
conducted by EAI (2008-2009 and 2022-2023) and Inwater Research Group, Inc. (2013-
2014).
Task 3b.7 — Reporting: EAI will prepare and submit to the COUNTY, USACE, FDEP, and
COASTAL TECH the following reports in support of regulatory permitting requirements.
■ Monthly summary reports will tabulate the dates and times of monitoring, names of
monitoring personnel, numbers of sea turtle emergences by species, and numbers
of nests marked and evaluated for reproductive success, as applicable. Monthly
reports will be submitted no later than the last day of the month following delivery of
services (e.g., March report due no later than April 30).
■ A year-end report will summarize in tabular format the numbers of sea turtle
emergences by species, nest fates of all marked nests, and reproductive success of
evaluated nests, including graphic representations, as applicable. The annual
summary report will be submitted to no later than 120 days following completion of
monitoring activities.
■ Permit -related reports will be prepared following the completion of monitoring
activities. All nesting activity and reproductive success for the project area will be
submitted to FWC using the application provided by FWC. A final excel spreadsheet
will be provided to the County when received from FWC.
Task 3c — Biological Monitoring - Hardbottom: COASTAL TECH, via sub -contract with CSA
Ocean Sciences Inc. (CSA), will provide biological services for post -construction monitoring of
the Project. In general, CSA will perform a Post -Construction Survey expected to be conducted
in Spring/Summer 2022 - consistent with the existing Biological Monitoring Plan (BMP) approved
by FDEP on July 30, 2021.
CSA will monitor and note field conditions in the Project area daily beginning in May 2021, when
Local sea conditions usually begin to improve, until completion of field work. Field conditions of
note will include wind direction and speed, wave height, wave period, and visibility, as
applicable, along with any significant weather conditions. Wave heights greater than 0.6 m
typically result in increased turbidity and reduced underwater visibility, which prevents surveys
from being reliably conducted.

St. Lucie County Work Authorization I
Pre, During, & Immediate Post Construction Support Scope of Services
Consistent with the B M P update, COASTAL TECH/CSA will perform the following sub -tasks:
Task 3c.1 — Nearshore Hardbottom Monitoring: Twenty-six cross -shore permanent
hardbottom monitoring transects beginning at the nearshore hardbottom edge and located
directly offshore of FDEP Monuments R-78.7, R-80.4, R-82.8, R-85, R86.3, R-88.7, R-90.4, R-
92, R-100, R-101, R-101.1, R-101.9, R-102, R-102.8, R-103, R-103.1, R-108.8, R-109.2, R-
109.7, R-110, R-111, R-112, R-112.3, R-113, R-2 (Martin County), and R-3 (Martin County)will
be established and monitored by CSA during the 2021 survey.
As part of the nearshore hardbottom monitoring, a marine biologist will collect qualitative
video documentation of the seafloor and associated biota along each of the 26 biological
transect lines. A species inventory of major taxonomic groups and a species list of fishes and
sea turtles observed during the survey will also be produced from each of the 26 biological
monitoring transects. Sand depth measurements will be collected at 1-m intervals along all
26 transects using a marked steel ruler, and the physical transitions between sand and
hardbottom along all transects will be recorded as line intercepts. Quantitative video will be
collected at 40 cm above the bottom of each transect for archival purposes.
American Academy of Underwater Scientists (AAUS)-certified nearshore hardbottom
specialists will determine percent cover of major benthic groups, average sediment depth,
and substrate type from 0.5 m2 quadrats along each biological transect for a total area of 10
m per 150 m transect. The number of quadrats per transect will vary based upon the length
of the transect but will be distributed along each transect so that at least 2.5 m2 of area is
sampled in each of the following zones: 0 to 30 m; 30 to 60 m; 60 to 100 m; and 100 to 150 m.
Digital photographs of each quadrat will be taken for reference at the time of monitoring.
Quadrats will meet prescribed FDEP BEAMR data collection criteria from the 2016 FDEP
Standard Operation Procedures for Nearshore Hardbottom Monitoring of Beach
Nourishment Projects.
Task 3c.2 — Nearshore Hardbottom Edge Mapping: Delineation of the nearshore hardbottom
edge will provide information on hardbottom exposure within the project area and allow for
determination of direct impacts, when occurring, due to hardbottom burial by Project fill.
Hardbottom formations have been documented to run parallel to the St. Lucie County South
Beach project shoreline. Therefore, the entire length of the nearshore hardbottom edge
between FDEP reference monuments R-96 in St. Lucie County and R-4 in Martin County will
be mapped during the pre -construction survey.
Two divers will swim the entire length of the hardbottom edge. Divers will tow a Differential
Global Positioning System (DGPS) buoy to record their track and will also record qualitative
digital video to document the nearshore hardbottom edge for a descriptive analysis (e.g.,
dominant benthic communities, vertical relief, sand cover). The camera will be positioned at
an oblique angle to the seafloor. Locations of breaks in the hardbottom edge or sand gaps
greater than 5 m in length will be noted during the survey.
Task 3c.3 — Side Scan Sonar Survev: CSA will subcontract Morgan & Eklund, Inc. (M&E) to
perform a side -scan survey to verify the locations of hardbottom within the project area. The
Page 7 of 8
November 4, 2025

St. Lucie County Work Authorization I
Pre, During, & Immediate Post Construction Support Scope of Services
side -scan survey will be performed between FDEP R-monuments R-97 in St. Lucie County
and R-4 in Martin County and offshore a distance of approximately 350 m. Hardbottom
mapping data collected during the side -scan survey will be (a) recorded and provided
digitally, (b) interpreted with other field data to prepare a summary map of nearshore
hardbottom extent and character.
Task 3c.4 — Data Analysis & Reporting: Data from Tasks 3c.1 to 3c.3 will be analyzed by CSA
and summarized in a draft report to document and characterize the baseline conditions in
the project area prior to construction. The draft report will be submitted to COASTAL TECH
and the County for review. Upon acceptance of the draft report, the draft report will be
submitted to FDEP. Qualitative descriptions based on video and diver observations will be
provided for substrate types, sediment movement, and benthic assemblages. Percent cover
of benthic groups and substrate within quadrats and average sediment depth will also be
determined. Results of this survey will provide a basis for comparison future subsequent
post -construction monitoring data to determine changes among transects and between
years— potentially attributable to the Project.
