challenges include conflicts with a historic building and
<br />utilities, planning accommodations for future park projects,
<br />and considering alternatives within grant funding limitations.
<br />Developed a hydrodynamic model to identify overland flood
<br />pathways throughout the Project Site. This information
<br />was used to inform the best wall alignment that maximized
<br />protection of the site from coastal storm surges.
<br />Hurricanes Matthew & Irma FEMA Berm Restoration,
<br />St. John’s County, St. John’s County, FL. The passing of
<br />Hurricane Matthew in 2016 along with Hurricane Irma in 2017
<br />caused significant coastal erosion throughout segments of
<br />shoreline in St. John’s County located in north-eastern Florida.
<br />The county obtained FEMA funding to construct a beach fill
<br />project to recover the sand losses sustained throughout these
<br />storm events. Provided coastal engineering services including
<br />the analysis of 20 years of historic shoreline positional data to
<br />quantify shoreline movement trends throughout the 20.2-
<br />mile Project Area. Provided analysis on the sediment samples
<br />obtained throughout the foreshore and nearshore zones to
<br />visualize typical grain size distributions along each shoreline
<br />reach. Additionally, assisted in the formation of a Joint Coastal
<br />Permit (JCP) application, providing input on how the design
<br />of the beach fill project will not alter the coastal processes or
<br />navigational practices native to the Project.
<br />Naval Air Station (NAS) Key West Dredge Readiness
<br />Plan, USACE Jacksonville District, Key West, FL The
<br />Key West Harbor Channel is historically a low shoaling channel
<br />due to natural hardbottom and limited sediment sources.
<br />Shoaling material typically consists of rock, sands, and silt.
<br />Led a team tasked with formulating a Dredge Readiness Plan
<br />for the USACE and Naval Air Station (NAS) Key West. The
<br />work involved an analysis of the historical shoaling rates of
<br />the channel, an investigation into nearby receiver sites, and
<br />a multicriteria analysis to rank sites based on stakeholder
<br />provided metrics. The final Plan outlined required short
<br />term actions for dredge readiness with estimated costs and
<br />timelines, and recommendations for material placement
<br />and management over the long term (present to 50 yrs) that
<br />incorporates beneficial use of dredge material (BUDM).
<br />Port Everglades Harbor Monitoring – Dredging &
<br />Beach Nourishment, SOL Engineering (end client:
<br />USACE Jacksonville District), Port Everglades, FL.
<br />Port Everglades located in Fort Lauderdale, FL underwent
<br />maintenance dredging of approximately 200,000 cy of
<br />sediment to maintain appropriate depths to accommodate
<br />deep-draft container ships, gas carriers, and cruise ships that
<br />the port serves. Worked with the field team that provided
<br />in-water sampling services to collect water quality samples
<br />and provide turbidity monitoring throughout the pre-dredge,
<br />during-dredge, and post-dredge phases. Beach nourishment
<br />on the shoreline adjacent to the port was observed and
<br />monitored throughout the sand placement activities. Assisted
<br />in the data collection, analysis, and subsequent reporting
<br />deliverables throughout the project lifecycle.
<br />Lake Worth Inlet Sand Transfer Plant Integrity
<br />Assessment, Town of Palm Beach Dept. of Public
<br />Works, Palm Beach, FL. The Town of Palm Beach, in
<br />cooperation with Palm Beach County, owns and operates a
<br />fixed sand transfer plant located at the northern border of
<br />Palm Beach barrier Island. The plant is tasked with diverting
<br />sediment that accretes on the northern jetty of Palm Beach
<br />Shores to south of the southern jetty to mitigate downdrift
<br />beach erosion. Assisted in the field asset management
<br />assessment of the Plant inclusive of all mechanical and
<br />structural components necessary to its operation. The
<br />objective of the project was to locate an obstruction in one
<br />of the discharge lines. make a determination of the overall
<br />condition of the plant and recommend any alternatives
<br />that could be implemented to ensure continuous sand
<br />replenishment of the shoreline adjacent to the southern jetty.
<br />Town of Palm Beach Reach 2 Sand Forepassing,
<br />Town of Palm Beach Dept. of Public Works, Palm
<br />Beach, FL. In January 2022, the Palm Beach Harbor
<br />Maintenance Dredging and Bypassing Project commenced
<br />dredging operations within the federal navigation channel.
<br />Approximately 400,000 CY of material were placed south of the
<br />inlet to restore the shoreline and supplement sand bypassing
<br />around the inlet. A portion of this material was forepassing
<br />to the Reach 2 segment of the shoreline which encompasses
<br />~1,800 linear feet along northern Palm Beach Island.
<br />Supported the Town by providing regulatory and construction
<br />oversight of the forepassing operations. This forepassing effort
<br />helped enhance the resiliency of the coastal system to provide
<br />a buffer from coastal storm risks..
<br />Curry Hammock State Park Tidal Connections
<br />Restoration, Florida Department of Environmental
<br />Protection (FDEP), Marathon, FL. Curry Hammock State
<br />Park is located along U.S. Highway 1/Overseas Highway (U.S.
<br />1), Marathon, Monroe County, Florida. Curry Hammock State
<br />Park is located between Florida Bay to the north and the
<br />Atlantic Ocean to the south. During the development of this
<br />area and the construction of U.S. 1 during the last century
<br />(early 1900s), the historical tidal connections between
<br />the Florida Bay and the Atlantic Ocean were filled in. The
<br />tidal restoration project aims to restore the historical tidal
<br />connections at the two sites by re-establishing circulation
<br />between the surface waters of the Atlantic and Florida Bay.
<br />Provided coastal modeling and engineering services to design
<br />the tidal restoration structure and quantify the benefits to
<br />the water quality of the park. Constructed a calibrated 2D
<br />hydrodynamic model to quantify the flow rates and flushing
<br />times associated with the different design options to select
<br />the most effective alternative. Based on the modelled water
<br />currents and wave conditions, also provided calculations to
<br />inform the sizing of rock armor protection for the adjacent
<br />shorelines.
<br />Village of Indian Creek Seawall Assessment, Village
<br />of Indian Creek Public Works, Miami, FL. The Village is
<br />a man-made island located north of Miami Beach and along
<br />the eastern extents of northern Biscayne Bay. The island
<br />encompasses ~250 acres, a private golf club, residential
<br />homes, and ~13,800 LF of mixed shorelines (the majority
<br />of which are seawalls). The Village Police station is situated
<br />on the Miami Beach barrier island and contains ~375 LF of
<br />shoreline (seawall). Provided a review of the top of wall
