COLLIER COUNTY EMERGENCY SAND SOURCE EVALUATION

Abstract To meet the needs of future emergency beach nourishment projects, Collier County authorized Coastal Planning & Engineering, Inc. (CPE) to conduct reconnaissance level marine sand search investigations. During Phase I, a comprehensive review of the sediment resources offshore of Collier County was conducted to identify potential beach compatible sand sources for use in small emergency nourishment projects along the County’s coast. Five (5) main areas including the Gordon Pass Ebb Tidal Shoal, the 1996 CEC Ridge Deposit, the 2002 CPE Ridge Deposits, the Big Marco Pass Ebb Tidal Shoal and the Cape Romano Shoals were recommended for further investigation. The northern portion of the 2002 CPE Ridge Deposits and the Big Marco Pass Ebb Shoal were recommended for further review of existing data. The areas recommended for reconnaissance level investigations include the southern portion of the 2002 CPE Ridge Deposits, the Gordon Pass Ebb Tidal Shoal, the 1996 CEC Ridge Deposit and the sand ridges located off Cape Romano. Phase II investigations consisted of geophysical and vibracore surveys. The reconnaissance level investigation resulted in the identification of one (1) area that is suitable for further detailed investigation for development as an emergency borrow area. This area is recommended for further investigation although the shallow water depth and the distance to the recipient beach(es) should be considered during planning.

INTRODUCTION

To meet the needs of future emergency beach nourishment projects, Collier County authorized Coastal Planning & Engineering, Inc. (CPE) to conduct reconnaissance level marine sand search investigations. During Phase I, a comprehensive review of the sediment resources offshore of Collier County was conducted to identify potential beach compatible sand sources for use in small emergency nourishment projects along the County’s coast. Emergency nourishment projects that occur between major projects, often require small volumes of sand. These projects do not warrant a major dredging effort, and the disturbance associated with truck haul projects is undesired. Available historic investigation areas, potential sand resources and borrow areas were compiled and superimposed on NOAA bathymetric data. Geophysical and geotechnical data collected within these areas, as well as any reports discussing the findings, were then reviewed. Based on this analysis, a single map identifying potential deposits of beach compatible material was generated (Figure 1). Phase II investigations, which are the subject of this report, focused on these potential deposits.

Phase II investigations consisted of geophysical and vibracore surveys. In August 2007, seismic reflection, magnetometer and bathymetric survey data was collected. In November 2007, vibracores were collected from the most promising areas. The sand resource areas that were identified were analyzed using GIS procedures that integrated the bathymetric survey, seismic reflection profiling and vibracore data to estimate deposit thickness and sedimentary characteristics. The reconnaissance level investigation resulted in the identification of one (1) area that is suitable for further detailed investigation in order to develop it as an emergency borrow area.

This report summarizes the results of the offshore geophysical and geotechnical investigations that led to the identification of a potential sand resource area. Geological background and analysis of legacy data are discussed first, followed by a description of field activities, analysis of results from field measurements, and finally definition of the characteristics of the identified sand resources.

Geographic Location Collier County is bounded to the west by the Gulf of Mexico, to the north by Lee and Hendry Counties, to the east by Broward and Miami-Dade Counties and to the south by Monroe County (Figure 1). Collier County covers an area of approximately 1,280,000 acres and has over 50 miles of coastline.

GEOLOGICAL BACKGROUND

Coastal Geological Framework A description of the geologic setting of the region is central to the understanding of bedrock seafloor surfaces and the sediments sitting on them. The nature of sedimentary deposits determines sand quality and its potential use for beach nourishment. It is, thus, helpful to understand the general shelf environments because the distribution of beach-quality sands on the seabed is not random, but spatially well defined in terms of stratigraphy, grain composition, age of materials and erosional-depositional events.

The western coast of Florida is part of a large primary geological feature referred to as the eastern Gulf of Mexico Sedimentary Basin, which is further divided into the North Gulf Coast Sedimentary Province and the Florida Peninsula Sedimentary Province (SCHMIDT and CLARK, 1980). The Florida Peninsula, a large carbonate platform containing a thick, non-clastic sedimentary sequence predominantly composed of carbonates and anhydrites, was constructed between the middle Jurassic (180 MYA) and the late Miocene (5 MYA). This ancient carbonate platform forms the proximal portion of the west Florida shelf-slope system and exerts large-scale control on coastal geomorphology, the availability of sediments, and wave energy (HINE et al., 2003). Since the early Jurassic, the plateau has been alternately dry land during times of low sea level, or covered by shallow seas during periods of high sea level, once forming a shallow tropical sea 500-miles long and 400-miles wide. This warm, clear water environment was similar to the modern Bahama Banks in that the sediments produced were almost entirely calcium carbonate (CHEN, 1965). Approximately 4000 ft (in north central Florida) to 20,000 ft (in southernmost Florida) of carbonate and marine sediments were deposited, which eventually lithified to create the limestone formations that presently underlie Florida. During the initial evolution of the Florida Peninsula, sediments began to cover late Triassic to early Jurassic (c. 205 MYA) mafic volcanic suites that make up the crystalline basement rocks (WHITE, 1970; WINSTON, 1971). Development of the thick sedimentary cover that makes up the Florida Peninsula was also associated with the early Jurassic embayment of the Gulf of Mexico basin, with its center of deposition passing through the southern archipelago and paralleling the coast, (WINSTON, 1992). During the same time or during a later emergence, there appears to have been a tilting of the plateau along its longitudinal axis causing a partial submergence of the West Coast, partly

accounting for the wide estuaries and offshore channels found along the west coast of Florida.

The underlying antecedent topography of the Tertiary (2–65 MYA) limestone surfaces, as well as their hardground exposures, significantly influence the orientation and geographic location of Holocene (last 10,000 years) barrier islands and sand ridges along the west coast of Florida, as discussed by EVANS et al. (1985) and HINE et al. (1986). Coastal orientation is generally NW-SE along the southwest coast of Florida. However, there are major offsets at Indian Rocks (Pinellas County), Sanibel Island (Lee County) and Cape Romano (Collier County). The underlying pre-Quaternary (1.8 MYA) surface is composed of irregular karstic limestones that partially control barrier island development, position, and tidal inlet opening (STAPOR et al. 1991; GIBEAUT and DAVIS, 1988). The present coastal barrier islands likely formed close to their present location during the latest, relatively stable, stages of the Holocene transgression approximately 4000 to 5000 years ago (BLAND, 1985, DAVIS, 1997, EVANS et al., 1985). Historic shoreline data for recently evolved coastal barrier islands and stratigraphic data based on core logs from older barrier islands indicate that they formed in response to a gentle wave climate that transported sediments onshore to shallow water where they shoaled upward to intertidal and supratidal levels (LOCKER et al., 2003).

General Geological Description of Collier County From a geomorphological point of view, Collier County lies within the Southern or Distal Physiographic Zone (WHITE, 1970). The dominant geomorphic or morphostructural (combined morphology or shape and internal geological structure) subaerial features in the County are identified as the Immolakalee Rise, the Big Cypress Spur, and the Southern Slope (WHITE, 1970). Coastal Collier County has many landforms characteristic of a sedimentary shore and is broadly characterized by a range of coastal barriers, estuaries and lagoons, inlets, wetlands and swamps, and karst features. HINE et al. (1986) formally identifies the various landform units as the West-Central Barrier Chain.

Beneath Collier County, basement rocks consist of predominantly late Triassic- Early Jurassic mafic volcanic rocks (WINSTON, 1971), formed when continents were still joined together in the macro-continent called Pangea. Mesozoic rocks in Collier County are comprised of over 5,000 feet of carbonates. Significant quantities of siliciclastic material are present only in the Miocene and younger sediments (CAMPBELL, 1988).

Most of coastal Collier County is thinly mantled with unconsolidated sand (the unconsolidated deposits generally thicken from south to north) that overlies eroded limestone of the Tamiami Formation (DREW and SCHROMER, 1984). Coastal sands are also reported to overlie marl and lime mud deposits (MCCOY, 1962). It is essential to note that the underlying antecedent topography of the Tertiary limestone surface (the drowned karst landscape) significantly influences the cardinal orientation and geographic location of Holocene barrier islands (EVANS et al., 1985; HINE et al., 1986). There is pronounced rock control of loci for sedimentary deposition, coastal configuration and shoreline position that must be appreciated when explaining coastal evolution and present

attempts to manage these dynamic systems that respond to many factors. Quaternary sedimentary accumulation has produced a significant dislocation of the coastline at Cape Romano, which has several implications for interpretation of local morphodynamics. Cape Romano marks the southern end of the quartz sand dominated Gulf Barrier Island Chain. The siliciclastic to carbonate transition occurs rather abruptly around latitude 25°30' (CAMPBELL, 1988; SUSSKO and DAVIS, 1992).

Net longshore transport in Collier County is from north to south and the majority of the quartz sand transported past Cape Romano is deposited in a large shoal complex, referred to as the Cape Romano Shoals (CAMPBELL, 1988) or Tidal Sand Ridges as described by DAVIS et al. (1993). North of Cape Romano, chains of barrier islands and associated lagoons characterize the Collier coastline. There are some localized areas with longshore current reversals associated with wave refraction patterns adjacent to large ebb shoals.

Moderate wave energy conditions (average breaker height ranges between 0.10 and 0.50 m) along this microtidal coast characterize much of the West-Central Barrier Chain (TANNER, 1960). The relatively low wave energy along the Collier coastal sector produces distinctive beach types and provides a degree of shoreline stability, except on the downdrift sides of inlets and during storms (i.e. hurricanes). There are numerous small inlets that remain open along this low energy coast because wave and current action is minimal. Under high energy conditions, however, many of these types of inlets are prone to sediment accumulation and closure. Additionally, the low wave energy allows for the construction of large ebb tidal deltas, which store large volumes of sand (DAVIS et al., 1993). Flood tidal deltas along the west-central Florida coast are relatively inactive due to small tidal ranges, sheltered lagoons, and ebb dominated inlets (DAVIS and KLAY, 1989; FINKL, 1994).

The wide Continental shelf offshore of Collier County, described by DAVIS (1997) gently slopes seaward toward the central basin of the Gulf of Mexico and maintains shallow depths to 5.5 miles offshore to the 30 isobath. Shelf morphologies and coastal morphodynamics have received much attention from the scientific community in the last two decades due to their influence on the spatial distributions of mineral resources (WRIGHT, 1995), large scale beach behavior (SHORT, 1999), and barrier island evolution (OERTEL, 1979).

Various types of sand ridges (linear accumulations of sand bodies) occurring on inner shelves are common along many shores worldwide. These topographically positive sandy accumulations on the seafloor are recognized as relict (formed in response to prior sea level stillstands) sand bodies associated with lowered sea levels compared to those of today. In Collier County, prominent seabed morphologies on the inner continental shelf include linear sand ridges, some of which extend continuously for distances exceeding 4 miles. These ridges have asymmetrical profiles with steeper offshore gradients and are variously oriented singly or in groups from N-S to SW-NE. The grouped ridges occur in formations similar to the Cape Romano ridges in the southern part of the County. The isolated ridges appear to represent shoals associated with paleo-inlets (passes related to

5 COASTAL PLANNING & ENGINEERING, INC. CAC March 13, 2008 New Business VIII-1 8 of 94

formerly lower sea levels than present mean sea level) in offshore areas. These offshore relict deposits are not associated with contemporary coastal/marine processes and as such, they most probably can be related to paleo-coastal environments such as (ebb) shoals and bar beach systems. These deposits are geologically young, having formed during the Flandrian Transgression (most recent Holocene trend in sea-level rise that took place within the last 10,000 years) (DAVIS, 1997). Modern inner-shelf dynamic processes, such as the action of undertow currents and storm wave activity, reshaped and reworked the sedimentary architecture of these deposits to produce the morphologies presently seen.

Other commonly occurring features offshore of Collier County include various types of depressional (negative topographic) features that are incised into the karst surface and some surficial marls. When the continental shelf was exposed to surface geomorphic processes during low stands of sea level, small streams and some larger rivers cut into the karstified surface and persisted as valleys until sea level rose and they were infilled with recent marine and terrigenous sediments.

EQUIPMENT AND METHODS

The technical procedures, operational methodologies, analytical tools, and equipment used in this reconnaissance level investigation are described below. Due to the scope and precision required by modern sand search protocols, a wide range of geotechnical and geophysical survey methodologies are required such as navigation and positioning systems, bathymetric surveys and determination of sediment composition and depth via vibracoring and seismic reflection profiling. Magnetometer surveys are also required for cultural resource assessment prior to vibracore collection. On August 14, 2007, a concurrent seismic reflection, bathymetric and magnetometer survey was conducted off the M.V. Wendy Anna. Between 27 and 29 November 2007, thirteen (13) vibracores were collected from locations determined by the analysis of historic data and the results of the August geophysical survey. Table 1 lists the geophysical and geotechnical equipment used during these investigations.

Navigation Systems The navigation and positioning system deployed for the geophysical and geotechnical surveys was a Trimble Differential Global Positioning System (DGPS) interfaced to Hypack Inc.’s Hypack Max®. A Pro Beacon receiver provided differential GPS correction from the U.S. Coast Guard Navigational Beacon located at Tampa Bay, Florida. The DGPS initially receives the civilian signal from the global positioning system (GPS) NAVSTAR satellites. The locator automatically acquires and simultaneously tracks the NAVSTAR satellites, while receiving precisely measured code phase and Doppler phase shifts, which enables the receiver to compute the position and velocity of the vessel. The receiver then determines the time, latitude, longitude, height, and velocity once per second. Most of the time, the GPS accuracy with differential correction, provides for a position accuracy of one (1) to four (4) feet. This is within the accuracy needed for geotechnical investigations.

Hypack Inc.’s HYPACK MAX ® Data Collection and Processing Program Navigational, magnetometer, and depth sounder systems were interfaced with an onboard computer, and the data were integrated in real time using Hypack Inc.’s Hypack Max®. Hypack Max® is a state-of-the-art navigation and hydrographic surveying system. Online screen graphic displays include the pre-plotted survey lines, the updated boat track across the survey area, adjustable left/right indicator, as well as other positioning information such as boat speed, quality of fix measured by Position Dilution of Precision (PDOP), and line bearing. All data were recorded on the computer’s hard disk and transferred to a USB memory stick each day during the survey to back-up raw survey data. After post-processing, the navigation data (locational) stored in the Hypack Max® system was exported to AutoCAD and converted to ArcView shapefiles for analysis and report preparation.

Bathymetric Survey The Odom Hydrographic Systems, Inc.’s Hydrotrac, a single frequency portable hydrographic echo sounder, was used to perform the bathymetric survey. The Hydrotrac operates at frequencies of 24, 33, 40, 200, 210, or 340 kHz and is a digital, survey-grade sounder. Prior to use, the sounder was calibrated and checked periodically throughout the survey. Calibration was performed using an Odom Hydrographic Systems, Inc.’s Digital Pro® speed-of-sound velocity meter. Speed of sound through water and other selected parameters were adjusted to accurately reflect physical water conditions in the survey area.

Magnetometer Survey A Geometrics G-882 Digital Cesium Marine Magnetometer was used to perform a cursory investigation of magnetic anomalies within the potential sediment sources (Figure 2). The purpose of the magnetometer survey was to establish the presence, and subsequent exclusion zones around any potential underwater wrecks, submerged hazards, or any other features that would affect borrow area delineation and dredging activities. The Hypack Max® software recorded magnetic anomalies directly from the Geometrics magnetometer.

Seismic Reflection Profile Survey An EdgeTech X-STAR SB-216S was used to conduct the seismic reflection profile surveys (Figure 3). The X-STAR Full Spectrum Sonar is a versatile wideband FM sub-bottom profiler that collects digital normal incidence reflection data over many frequencies (2 to 16 KHz). This instrumentation generates cross-sectional images of the seabed (to an approximate depth of 60 feet in this survey). X-STAR SB-216S transmits an FM pulse that is linearly swept over a full spectrum frequency range (also called a “chirp pulse”). The tapered waveform spectrum results in images that have virtually constant resolution with depth.

The Chirp systems have an advantage over 3.5 kHz and boomer systems in sediment delineation because the reflectors are more discrete and less susceptible to ringing from both vessel and ambient noise. The full wave rectified reflection horizons are cleaner and more distinct than the half wave rectified reflections produced by the older analog systems.

The model SB-216s tow vehicle weighs approximately 100 pounds. The X- STAR SB-216s frequency range generates a high-resolution image of the sub-bottom stratigraphy in sand to a depth of 10-60 feet below the sediment/water column interface, which are the typical depths of interest for sand searches.

Figure 3. EdgeTech X-STAR SB-216S used to conduct seismic reflection profile surveys.

All sub-bottom data was recorded on the acquisition computer’s hard disk and transferred to a USB memory stick and/or portable hard drive at the end of each survey day to back-up raw survey data. Processing of the seismic data was accomplished with Chesapeake Technology, Inc’s SonarWiz.MAP +SBP® software. In addition to processing and interpretation, this software also produces georeferenced HTML’s exportable for incorporation into a GIS database. HTML’s are provided in Appendix 1.

Vibracore Survey Once potential sand targets were identified based on the analysis of the historic data, a plan was developed for a vibracore program that followed a logical sequence that optimized personnel, corporate resources, and time. Thirteen (13) vibracores were collected during this investigation.

The diver vibracore was configured to collect undisturbed sediment cores up to 10 feet in length. There are several benefits to the diver vibracore methodology. With divers on the seafloor conducting the vibracores detailed observations about the seafloor type can be made, divers can take measurements of the inside of the vibracore tube prior to sealing the core for extraction which gives accurate compaction values, and diver observations of the vibracore process can provide confirmation of vibracore refusal atop hard substrate.

The diver-operated vibracore system employed two scientific divers and a pneumatic vibracore system (Figure 4). The BH-4 style vibrator apparatus is a single piston, pneumatically driven vibrator that is retrofitted to a 3-inch aluminum pipe. An air hose array provides compressed air from a compressor on the deck of the support vessel. The two-person team of scuba divers collected and retrieved the vibracore sample. One diver was responsible for the buoyancy control of the apparatus as well as the demand valve that controls airflow to the apparatus from the support vessel. The second diver stabilized the apparatus at the seafloor and guided the tube into the sediment vertically. Once the desired penetration was attained, the pipe was cut approximately 1 to 2 feet above the

9 COASTAL PLANNING & ENGINEERING, INC. CAC March 13, 2008 New Business VIII-1 12 of 94

Figure 4. The BH-4 vibracore apparatus being deployed.

seafloor and the vibratory hammer assembly was raised to the surface via lift bags and retrieved by the crew on deck the support vessel. The exposed pipe on the seafloor was capped by the divers and pulled out of the sediment. Once the bottom of the pipe was sufficiently exposed, the bottom of the pipe was capped to limit the loss of sediment. The vibracore was then raised to the surface for recovery by the crew on deck the support vessel. The vibracore unit was deployed from the R/V Aqua Quest.

Each vibracore was measured, marked, cut into 5-foot sections and transported to CPE’s office in Boca Raton, Florida. There, the vibracores were logged by describing sedimentary properties by layer in terms of layer thickness, color, texture (grain size), composition and presence of clay, silt, gravel, or shells and any other identifying features. The vibracores were photographed, and wrapped in plastic. Vibracore logs and photographs are presented in Appendices 2 and 3, respectively. Sediment samples were obtained from irregular intervals based on distinct layers in the sediment sequence.

10 COASTAL PLANNING & ENGINEERING, INC. CAC March 13, 2008 New Business VIII-1 13 of 94

Sediment-Size (Mechanical) Analysis Sieve analyses were conducted on all sediment samples in accordance with American Society for Testing and Materials Standard Materials Designation D422-63 for particle size analysis of soils (ASTM, 2007). This method covered the quantitative determination of the distribution of sand size particles. Mechanical sieving was accomplished using calibrated sieves with a gradation of half phi intervals. Additional sieves representing key ASTM sediment classification boundaries were included to meet Florida Department of Environmental Protection (FDEP) standards.

Grain size results were entered into the gINT® software program, which computes the mean and median grain size, sorting, and silt/clay percentages for each sample using the moment method (FOLK, 1974). A grain size distribution curve and gradation analysis report for each sample was compiled. Gradation analysis reports and grain size distribution curves are presented in Appendices 4 and 5.

INVESTIGATION SEQUENCING

A methodological approach to marine sand searches, developed over the years by the CPE Coastal Geology and Geomatics team (FINKL, KHALIL and ANDREWS, 1997; FINKL, ANDREWS and BENEDET, 2003; FINKL et al., 2005; FINKL and KHALIL, 2005), was applied to this sand search investigation. In comprehensive marine sand searches like the Collier County project, CPE typically employs sequential survey procedures that maximize resources to effectively characterize offshore sand deposits. These sequential surveys collect preliminary data over relatively large expanses of seafloor in the form of surface grab samples, jet probes, and reconnaissance bathymetry prior to the collection of remotely sensed data (i.e. seismic reflection profiles, sidescan characterization of the seafloor and magnetometer surveys) and vibracores in smaller target areas. Reconnaissance-level surveys that cover large areas of the seafloor provide useful information that helps define smaller targets (areas with higher potential for containing materials that are suitable for beach nourishment) where more intensive (and more expensive) sand and cultural resource investigations are conducted.

Phase I Investigations The investigative sequence, shown in Figure 5, describes the logical progressions and interactions between different data sources and indicates the steps that were followed by CPE geologists and geophysicists during the Collier County sand search. During Phase I, CPE researchers conducted archival literature studies of the inner continental shelf area offshore from Collier County. During the Phase I review, historic data including past investigation areas, previously identified sand sources and previously developed borrow areas, was compiled and superimposed on NOAA bathymetric data. Geophysical and geotechnical data collected within these past investigation areas, sand sources and borrow areas, as well as any reports, were then reviewed.

Figure 5. Flow diagram showing the main phases of sand search investigations for the Collier County sand search.

While reviewing the historic data and reports, a list of sediment quality criteria was developed to help identify potential sand resources. The optimal mean grain size based on the native beach ranges from 0.30 mm to 0.45 mm. Sands with dry Munsell color values of 6 or lighter are considered acceptable. Material with these characteristics that also meets State of Florida sand quality guidelines is considered beach quality. Sand quality guidelines for the State of Florida are specified in Rule 62B-41.00 (j) F.A.C. Areas exceeding a distance of 10 miles offshore were eliminated from consideration. Any sand resources that did not meet these criteria were marked for exclusion from further investigation.

Results of the historic data and reports reviewed during Phase I of this sand search investigation and descriptions of the areas recommended for further study based on this review are briefly discussed below:

The U.S. Army Corps of Engineers (USACE) collected 14 nearshore core borings between Doctors Pass and Gordon Pass in an attempt to identify sand sources for beach nourishment. No suitable deposits were identified during this investigation. Two additional cores were collected at this time within Dollar Bay. The material within these cores was reported to be beach compatible, however the site was abandoned due to environmental concerns (USACE, 1972).

Coastal Engineering Consultants (CEC) investigated an area that extends from the Lee County boundary south to Cape Romano over several separate sand search

12 COASTAL PLANNING & ENGINEERING, INC. CAC March 13, 2008 New Business VIII-1 15 of 94

investigations. Seven sand deposits were identified in 1988 based on 146 vibracores and geophysical data (COASTAL ENGINEERING CONSULTANTS, 1988). In 1991 an additional 40 vibracores were collected. The areas previously identified were refined based on the 1991 data. An additional three potential borrow areas were also mapped (COASTAL ENGINEERING CONSULTANTS, 1991). All but one of these areas was later abandoned. A review of the available vibracore data shows that the material located within these areas is not beach compatible.

Offshore of Cape Romano has been studied extensively by the University of South Florida under Richard Davis (DAVIS et al. 1993; DAVIS et al., 1993; DAVIS and KLAY, 1991; DAVIS, 1989). Tidal sand ridges, known as the Cape Romano shoals, were identified and characterized based on this work. A total of 40 vibracores were collected from this area. Sediment within the shoals was described as being predominantly comprised of clean quartz sand having an average mean grain size of 0.20 mm. This area was subsequently investigated by CEC (COASTAL ENGINEERING CONSULTANTS, 2000). Twelve vibracores were collected on 6 ridges. Grain size information for the vibracores was not available for review, however vibracore log descriptions indicate the presence of shell in some areas, which may increase the grain size. Based on the potential for beach compatible material, four of the investigated Cape Romano shoals are recommended for further investigation.

During 1995-1996 CEC identified three new borrow areas based on data collected during previous investigations and 74 newly acquired vibracores. These areas, as well as previously mapped Borrow Area 6, were used in the 1995/1996 beach nourishment project. An offshore ridge was also identified during this investigation (COASTAL ENGINEERING CONSULTANTS, 1996). The cores on this ridge show a potential for beach quality material, it was therefore recommended for further investigation.

In 1998 Alpine Ocean Seismic Survey, on behalf of CEC, collected geophysical and geotechnical data within ten discrete areas between Marco Island and Wiggins Pass. During the investigation, 22 vibracores were collected and seismic, sidescan sonar and bathymetric surveys were conducted. No beach quality material was identified in these areas (COASTAL ENGINEERING CONSULTANTS and ALPINE OCEAN SEISMIC SURVEY INC., 1998).

In 2002, Coastal Planning & Engineering, Inc. (CPE) conducted a reconnaissance level investigation approximately 19 miles from Wiggins Pass to Big Marco Pass and extending from 0.5 to 13 miles offshore. The data collected included bathymetry, surface samples and jet probes. The initial five study areas were refined into 23 discrete offshore deposits and Big Marco Pass ebb-tidal shoal. Jet probe and surface sample data indicated that eight of the offshore deposits potentially contain beach compatible material (COASTAL PLANNING & ENGINEERING, 2003a,b). Two of these areas were eliminated because they were

13 COASTAL PLANNING & ENGINEERING, INC. CAC March 13, 2008 New Business VIII-1 16 of 94

further than 10 miles offshore of the County. Two (2) areas (N-5 and M-5) were eliminated after subsequent investigation. The four (4) remaining deposits are recommended for further investigation.

Sand volumes stored in Collier County ebb shoals were quantified by HINE et al. (1986) and DEAN and O'BRIEN (1987), who were attempting to estimate the impacts of inlets on coastal sand budgets. Methodologies used to estimate ebb shoal volumes included interpretation of aerial photographs, inspection of historical maps and analysis of documents, field investigations, and literature reviews. Two of the six ebb shoals reviewed, located at Gordon Pass and Big Marco Pass, are recommended for further investigation. Sand in the other four inlets are already being used on adjacent beaches.

Gordon Pass contains large quantities of material, however, further investigation would be required to determine if the material is beach compatible. Maintenance dredging of Gordon Pass is currently bypassed to the south. The northern lobe of the ebb shoal is believed to contain beach compatible sand. A portion of this material could be used for emergency projects with minimal impact to existing programs.

In addition to the work performed by HINE et al. (1986) and DEAN and O'BRIEN (1987), Big Marco Pass has also been investigated by CEC (1988, 1991, and 1996), HUMISTON & MOORE (2001) and CPE (2003a,b). The ebb-tidal shoal was found to contain beach compatible material and has been partially dredged for the recent Hideaway Beach Project. A small volume of suitable material is believed to remain in the Big Marco Pass shoal, and it is therefore recommended as a potential source for emergency nourishment projects.

CPE (2004) investigated sand ridges 5 to 7 miles offshore of Naples and Marco Island, the ebb shoal of Big Marco and Capri Passes, and sand ridges located northwest of Collier County (Tom's Hills), in federal waters. During this investigation 50 vibracores and detailed seismic data were collected to identify and delimit beach-compatible borrow areas. Three deposits were identified, two were located in Tom’s Hills (T-1 and T-2) and the third (N5) was located 5 miles offshore of Naples. Deposits T-1 and T-2 are beach compatible, however they are too far away to be considered for use in this program. Deposit N5 has an average silt content greater than 5%, and is therefore not considered to be beach compatible. M5, located 5 miles offshore Marco Pass, was initially investigated by using detailed seismic lines. The seismic lines indicate that sand deposits in area M5 are of limited lateral extent and thickness. This area was not selected for further geotechnical investigation.

A single map identifying promising areas requiring additional analysis, as well as fully investigated resources was generated (Figure 1). Sites containing or potentially containing beach quality material have either been previously dredged or have been marked as areas recommended for additional investigation. A total of twelve (12) areas

14 COASTAL PLANNING & ENGINEERING, INC. CAC March 13, 2008 New Business VIII-1 17 of 94

have been recommended for future investigation. These can be grouped into five (5) main areas: Gordon Pass Ebb Tidal Shoal, 1996 CEC Ridge Deposit, 2002 CPE Ridge Deposits, Big Marco Pass Ebb Tidal Shoal and Cape Romano Shoals (Figure 6). The northern portion of the 2002 CPE Ridge Deposits and the Big Marco Pass Ebb Shoal have been recommended for further review of existing data (Figure 6). The areas recommended for reconnaissance level investigations include the southern portion of the 2002 CPE Ridge Deposits, the Gordon Pass Ebb Tidal Shoal, the 1996 CEC Ridge Deposit and the sand ridges located off Cape Romano.

Phase I Investigation Results The majority of offshore areas within 10 miles of the shoreline have been previously investigated to various degrees. The remaining uninvestigated areas are not recommended for investigation for the purpose of small scale emergency projects. The offshore portion of Figure 1 identifies three types of areas: previously investigated areas; previously dredged areas and areas recommended for additional investigation. The previously investigated area boundary is a compilation of all investigation area outlines found during this study. Beach quality material was not located in the majority of these areas. Sites containing or potentially containing beach quality material have either been 1) previously dredged or are 2) marked as areas recommended for additional investigation. Twelve (12) deposits that potentially contain beach compatible material have been recommended for additional investigation based on the review of previous work. In order to determine the compatibility of the material within the potential sand deposits, the collection of reconnaissance level seismic and bathymetry as well as shallow penetration vibracores was recommended.

Phase II Investigations During Phase II investigations, CPE researchers conducted reconnaissance level geophysical and vibracore surveys within the areas recommended for additional investigation. Based on the analysis of historic datasets, locations for geophysical tracklines were selected. Areas that contained the greatest thickness of sand and which were devoid of rubble layers were identified as promising targets for the seismic survey. A joint seismic reflection profiling and magnetometer survey was conducted in August 2007. Based on analysis of the seismic data, vibracore locations were identified. Vibracores were collected in November 2007. Figures 7a, 7b and 7c show the location of the geophysical seismic lines and vibracore locations. The geophysical data, coupled with analysis of the new vibracores was used to determine the thickness of sediments and to ascertain the presence of undesired rock and/or material unsuitable for dredging (Figure 8). One (1) sand resource area was identified during this investigation.

Phase III Investigations Future Phase III investigations, together with cultural resource assessments, will complete the final phase of the sand search by incorporating the final identification and characterization of beach compatible sand sources. Principle tools for final borrow area delineation will include detailed vibracore and seismic surveys complemented by

This report summarizes the findings from the second phase of the sand search and provides recommendations for a detailed Phase III investigation. Results from reconnaissance level vibracoring, seismic reflection profiling, and magnetometer surveys are used to identify sand resource areas recommended for development of small emergency borrow areas.

RESULTS AND DISCUSSION

Areas Recommended for Additional Review of Existing Data

2002 CPE Ridge Deposits A detailed review of the existing seismic data was conducted for the northern 2002 CPE Ridge Deposits. The seismic data indicates a limited thickness of sand (average 2-3 ft thickness). The jet probes and vibracores collected within this area indicate that there is a potential for a high silt content (in excess of 5%). This area is not recommended for further investigation due to the limited thickness of material and the potentially high silt content.

Big Marco Pass Ebb Tidal Shoal A portion of this area was permitted by Humiston & Moore Engineers and was used in the 2005 Hideaway Beach Nourishment Project. A review of the material indicates that there are two distinct sediment types remaining in the investigated area, fine grained sand and shelly sand. The fine grained sand averages approximately 0.14 mm and is therefore too fine to be used. The shelly sand does not meet Florida State sand quality guidelines as it contains more than 5%, by weight, fine gravel which is predominantly shell. Mixing of these two sediment types to create a beach compatible product during placement is not likely due to the distribution of the material. Because of the potential for shell and the undesirable grain size, this area is not recommended for further investigation.

Areas Recommended for Reconnaissance Level Investigations

Gordon Pass Ebb Tidal Shoal Vibracores CCVC-07-12 and CCVC-07-13 were collected from the Gordon Pass Ebb Tidal Shoal potential sand resource area (Figure 7a). Vibracore CCVC-07-12 contains sand with less than 5% silt and trace clay from the top of the core down 5.6 ft. The mean grain size is 0.13 mm. The remaining 3.7 ft contains a significant amount of clay and shell. Vibracore CCVC-07-13 contains sand with less than 5% silt from the top of the core down 2.0 ft and mostly clay with shell in the remaining 3.3 ft. Although the uppermost material has a low silt content, the mean grain size is too fine to be used. Thus, this area is not recommended for further investigation.

21 COASTAL PLANNING & ENGINEERING, INC. CAC March 13, 2008 New Business VIII-1 24 of 94

1996 CEC Ridge Deposit Vibracores CCVC-07-01, CCVC-07-02, and CCVC-07-03 were collected from the 1996 CEC Ridge Deposit potential sand resource area (Figure 7a). Vibracores CCVC- 07-01 and CCVC-07-02 contain sand with an average of 4% silt from the top of the core down 2.7 ft. The mean grain size of this material is 0.17 mm. The remaining recovered material below this, 0.6 to 0.9 ft, contained silt greater than 5%. Vibracore CCVC-07-03 contained sand with an average of 5% silt down to a recovered length of 4.4 ft. Due to the fine grain size and potential for material containing greater than 5% silt, this area is not recommended for further investigation.

2002 CPE Ridge Deposits Vibracores CCVC-07-04, CCVC-07-05, CCVC-07-06, CCVC-07-07, CCVC-07- 08 and CCVC-07-09 were collected from the southern portion of the 2002 CPE Ridge Deposits potential sand resource area (Figure 7b). Vibracore CCVC-07-04 contains mostly clay. Vibracore CCVC-07-05 has sand with less than 5% silt in the top 1 ft of the core (mean grain size of 0.23 mm), while the remaining 3 ft is mostly shelly sand with rock and clay. Vibracore CCVC-07-09 contains only 1.1 ft of recovered material that is mostly shelly sand and clay. Vibracore CCVC-07-06 has 1.7 ft of recovered material that is mostly shelly sand, clay, and rock. CCVC-07-07 has sand with less than 5% silt in the top 0.8 ft. The remaining 1.9 ft of the core contains an average of 7% silt, along with clay and rock. Vibracore CCVC-07-08 has sand with an average of 6% silt in the top 0.5 ft and shelly sand. This area is not recommended for further investigation.

Cape Romano Shoals Vibracores CCVC-07-10 and CCVC-07-11 were collected from the Cape Romano Shoals potential sand resource area (Figure 7c). Vibracore CCVC-07-10 has sand with less than 5% silt in the top 3.9 ft of the core. The mean grain size is 0.27 mm. The remaining 1.5 ft contains mostly sand with shell, and trace clay. Vibracore CCVC- 07-11 has a total recovered length of 7.6 ft, all of which has sand with less than 5% silt and a mean grain size ranging from 0.15 to 0.18 mm. CEC (2000) identified approximately 7 million cy of potentially beach compatible material within the Cape Romano Shoals. This area is recommended for further investigation although the shallow water depth and the distance to the recipient beach(es) should be considered during planning.

CONCLUSIONS

The Cape Romano Shoals have been identified as an area qualifying for Phase III investigations. Additional investigation should include the collection of bathymetric data and additional vibracores to further characterize the material within this area and to provide a volume of potentially beach compatible material. The shallow water depth and the distance between the Cape Romano Shoals and the recipient beach(es) should be considered during planning.
