Executive Summary Alpine Ocean Seismic Survey, Inc. was contracted by the Town of Southold, New York under a Consultant Agreement dated December 31, 1997, to carry out a Geophysical Investigation offshore Duck Pond Point to Horton Point. The purpose .of this survey project is to locate an offshore sand source within a reasonable distance of Kenney's Beach that can be used in a beach nourishment project. In addition to the offshore search, upland sand sources were investigated in order to determine the _quality and cost of trucking and placing land source sand on the beach. Field work on the project commenced on. February 11, 1998, with a bathymetric and seismic survey and was completed on March 27, 1998, when the last remaining beach samples were collected. Final data analysis was completed at Norwood on April 24, 1998. The scope of work included: 1) 61 miles of bathymetry and high resolution seismic survey, 2) offshore vibracore sampling at 24 locations, 3) collection of 66 beach samples, 4) identification of seven (7) inland sand sources and 5) compilation of existing data and references pertinent to the project area. Beach samples and Vibracore samples were all analyzed for grain size distribution and statistical data developed by graphical methods in accordance with procedures used by the US Army Corps of Engineers. Based on the analysis of all data collected, a potential borrow area meeting the criteria for beach renourishment was identified. This borrow area site covers approximately 250,000 sq. yds. and can potentially yield 1,000,000 cubic yds. of beach quality sand. The same site should conservatively yield 277,000 cubic yds. Inland sand sources have been identified at 7 locations which could provide sand in quantity and quality required for beach nourishment at an emplacement cost of about $7.20 to $7.55 per cu. yd. However, environmental considerations imposed by heavy trucking traffic in the area, length of project duration and adverse effects on local road surfaces appears to make this option impractical. i 1.0 INTRODUCTION The project was completed by Alpine Ocean Seismic Survey, Inc. on behalf of the Town of Southold , New York under the consultant agreement dated December 31, 1997. The work described herein was performed.for.the Town of Southold as part of the Town's study of the shoreline erosion problem between Duck Pond Point and Horton Point. The area included in the study is shown on Figure.1, Regional Map. Specific objectives of Alpine's part in the study included the following general scope of work: • a bathymetric survey of the offshore area (3.25 miles x 1.4.miles) centered at Kenney's Beach. • a seismic survey using a high resolution subbottom profiler to identify subsurface structures in potential borrow areas. • an offshore vibracoring program at 24 locations to sample for potential beach nourishment material. • a beach sampling program to determine the grain size range of sands on the existing beaches. o a study of possible Inland sources of sand to determine their quantity, suitability, and cost of placement on the existing beach. • a compilation of existing data and references pertinent to the study area. - The final objective of the project is to present the study results in a convenient summary format, as well as a tabulated format to assist the Town of Southold in its decision making process. Following a brief description of the project background and geologic settings, this report will describe the results .of bathymetric and seismic survey, and show the correlation with the results obtained during the vibracoring sampling. Sedimentological data is developed from the beach sampling program and compared to the sedimentological data collected by the vibracore for identifying those areas best suited for borrow material. A potential borrow area is identified and estimates of volume of material is given.- This report also contains a review of possible sources of inland sand resources with estimates given as to the cost of emplacement on the beaches and comments as to the possible environmental impact of a land operation.

Figure 1 : Regional Map No shallow seismic reflection surveys have been run previously in the study area. An extensive series of seismic lines has been run down Long Island Sound at approximately 1 mile intervals offshore of the study area, These lines do not reach the seaward margin of the study area. In general, the first (shallowest) horizon is. interpreted to be a marine unconformity dating from the inundation of the Sound after the last deglaciation. On this surface there appears to be a buried paleoshoreline at an elevation of between -25 and -27 meters below the existing seabed. 3 2.0 SOUTHOLD PROJECT BACKGROUND AND GEOLOGIC SETTING The north shore of Long Island was at the margin of the glacial ice cover during the last (Wisconsin) glaciation which arrived around 21,750 years ago. The surficial geology is dominated by glacial deposits. The bluff crest is a subsection of the Harbor Hill Moraine called the Roanoke Point Moraine. The Roanoke Point Moraine consists of a till deposit. (the Wildwood Till) over an outwash deposit (Centerville Sand). The sandy outwash is characterized by ice-shoved alluvium deposits. Reworking of this material supplies a wide range of grain sizes to the littoral zone. Large boulders are found in place at the shoreline and offshore beaches tend to be coarse-grained, often with a very coarse lag basement under the active sand-or-gravel beach deposits. Fine grained sediments are also supplied locally but they tend to be washed offshore except where they are deposited in isolated, and sometimes ephemeral, deposits locally. Active sediment transport along Long Island's north shore is compartmentalized among a series of headlands and inlets. Sediment supply to the littoral creeks is from bluff erosion and longshore transport is driven by regionally generated wind waves in Long Island Sound. Northwest winds are both the predominant and prevalent winds affecting wave activity along the north shore. Net longshore transport, therefore, tends to be from west to east apparently decreasing from about 6,600 tons per day at Wading River to below 1,990 tons per day near Riverhead according to a study by Tanski, J.J. (See references Section 7.0). The local shoreline orientation and variation in the_wind wave climate, of course, modify the longshore transport. Under the proper conditions along a curving shoreline, sand can be driven into the center of the stretch from either headland. Sand then tends to accumulate offshore in a bar or series of bars between headlands. At least one such bar is found in the study area (Barrier Bar). The shoreline to the east of Goldsmith Inlet has receded since the construction of the jetty (Figure 2). A study by Davies of Al. in the early 1970's examined the condition of the beach and bluff at four stations between Goldsmith Inlet and Horton Point. In terms of the present study these locations are approximately 500 feet east of the inlet (Station 136), 1.25 miles east of the inlet (Station 137), 2 miles east of the inlet (Station 138) and at Horton Point (Station 139). At these locations the conditions were described as follows: Station Bluff Recession Medium Grain Size (mm, Phi units) Beach Width ft/yr.

Field procedures combined bathymetric .and seismic survey.techniques over a frequency range suited for best resolution and penetration to reveal the shallow geologic structure; vibracoring methods for a long and continuous sediment record; analysis of grain-size distribution; and compatibility analysis techniques described in the Shore Protection Manual (1984). Computer-assisted mapping and calculation techniques were used for a quantitative presentation of results. Results of the seismic survey helped to understand the geologic subsurface structure, to guide the selection of core sites as well as to provide the basis for estimating the volume of borrow sands available in the project area. Vibracores allowed direct inspection of borrow material -and a comparison with existing beach sands in _the renourishment area. The interpretation of the seismic records is summarized on Chart 3 -for convenient geographic referencing. Core-materials were analyzed for stratigraphic sequence and sedimentologic parameters. The final product includes estimates of sand volumes available in the project area, which are ranked in comparison with natural beach sands. 3.1 Navigation Navigation- procedures for the bathymetric, seismic survey and vibracoring operations were based on. the Trimble 4000 Series Differential Global Positioning System (DGPS). The Trimble unit received differential corrections from US Coast Guard base stations at Sandy Hook, New Jersey and Montauk Point, New York through a Starlink USCG HF data link receiver. The Starlink . system automatically locks onto the. strongest Coast Guard signal, which results in optimal horizontal positioning during vessel operations. The navigational data. from the Trimble DGPS was acquired, and processed using the Hypack hydrographic software for the Bathymetric, Seismic Survey and Sextant Software for the Vibracoring operations. .Both systems logged positions, and graphically displayed the vessel in relation to the pre-plotted survey lines and core locations. During the bathymetric and seismic survey, fix positions were obtained at distance.intervals of 100 feet. 3.2 Bathymetric Survey The bathymetric survey and seismic profiling were performed simultaneously using Alpine's 19' Aluminum hulled hydrographic survey boat, Guppy II. Soundings were taken with an Innerspace 448 digital echosounder with a 200 Khz transducer. The Innerspace records are recorded in both analog and digital format.. Digital soundings were logged at 25 foot intervals along each survey track. The echosounder was calibrated each survey day by a 20 foot bar check. 4 The average sound velocity computed by the bar check was 4620 feet per second. Tides were monitored using a Coastal Leasing "Microtide Meter° installed on the bottom in 20.feet of water near Goldsmith's Inlet. Soundings were reduced to NAVD 88. 3.3 Seismic Survey A continuous sub-bottom seismic reflection survey was .completed using an Ocean Research Equipment (ORE) Corp. Model 1032 sub-bottom profiler. The ORE profiler was operated at a frequency output of 5.0 kHz at a pulse length of 0.2 milliseconds. . The survey arrangement included 1) an over-the-side mounted variable frequency transducer -array, Model 132, 2) a 10 kW transceiver, Model 140, 3) an EPC.1086 Digital Graphics Recorder. Digital Data Was stored through an Elics Delph 2 system on an MO drive. Recorder sweeps were set at 60 milliseconds full scale. Resolution of the ORE system is approximately 1 foot. . 3.4 Vibracores - A Model 271 B Alpine Pneumatic Vibracorer configured to take cores 20 feet in length, was used to retrieve 24 cores from the area. The Model 271 B consists of an air-driven vibratory hammer assembly, an aluminum H-beam, which acts as a vertical guide for the vibrator, a set- of four steel support pads and legs to hold the beam upright, a 4-inch diameter steel coring pipe, a cutting edge, a core retainer, and a plastic core liner fitted into the core pipe. During operation, an air hose array provided passage of compressed air from a deck-mounted compressor to drive the vibracorer. A penetrometer was used to record the time and depth of penetration by the core pipe into the seafloor. In cases where the vibracorer did not penetrate to .a.full 20 feet. a jetting technique was used to increase core penetration and retrieval of sediments. Once the vibracore penetrated to refusal, the equipment was returned to the surface, the core liner removed, and the vibracorer was deployed.for a second run with a fresh coreliner installed. During the second run, a jet pump was used to jet the core pipe to the depth of previous refusal where vibration of the vibracore system again commenced. Once on the deck, the core samples in the plastic liner were cut into 5-foot lengths, .labeled, capped, and sealed. Full penetration and at least 90% recovery was achieved at each location except Core location 11. Core 11 was abandoned after a partial wash out of the core sample showed the sediment to be an organic silt. 3.5 Beach Profile Samples A total of 66 samples were. collected from 10 profile positions between Goldsmith's Inlet (Profile 6) to the NE end of Kenney's Beach (Profile 14). The 5 onshore and nearshore samples-(Dune Base to Low Water Step) were collected using a post hole digger. Each Sample was taken from 6" to about 12" below the , surface. The top sample, from the surface to 6" in depth was set aside. . A second sample from the same hole was placed in plastic bags and annotated with profile number, distance measurement in feet offshore from profile monument and annotated by number and sample location description (dune base, berm, mid beach, etc.) Offshore samples which included those classified as trough ,-rise, and bar were collected__ using a Van_ Veen grab sampler with a bucket capacity of approximately 600 cubic inches. An electric winch mounted on the Guppy II was used in the offshore sampling. . 3.6 Data Analysis Methods Data analysis to determine the quality of sand resources in the potential borrow area consisted of combining information provided by bathymetric and seismic sub-bottom profiles with sedimentologic data derived from the vibracores. This analysis was developed in two formats according to the scope of the work. First, the data were spatially summarized in a series of large format charts depicting survey track lines (Chart 1), Bathymetry (Chart 2) and distribution of subbottom sediment -types and thickness (isopach) (Chart 3). .Sedimentologic data were also summarized in the form of core logs depicting the shallow stratigraphy of the borrow area, as well as in a series of plots_and data sheets describing the texture of individual and composite samples from the vibracores. , Once the seismic data were acquired, a chart showing seismic track lines and fix points was produced using the Intergraph Microstation computer assisted design (CAD) software. This chart serves as the base map to locate the results of all other analyses performed under this study. All results were coordinated in the New.York State Long Island Lambert Coordinate System.(NAD 83). Strip-chart records of the seismic survey were inspected for acoustic reflecting horizons. Reflecting horizons were.noted and located according to fix points marked on the seismic records. Once the seismic records were reviewed, the results were contoured on the base chart to show the isopach, of the uppermost or .near- surface-reflector. The subsurface structure interpreted from the seismic data was then used to make an initial selection of 12 vibracore locations. Other locations were added as initial shipboard inspection of core indicated where additional sampling would be most helpful. The 24 vibracores retrieved from the offshore area were split and inspected for lithology. The core material was described according to ASTM standards. A log sheet was generated for each core similar to Engineering Form 1836 used by the US Army, Corps of Engineers. Individual sediment samples from each core were analyzed for grain-size distribution using mechanical sieving methods - 6 according to ASTM standards and. classified according to the Unified .Soils . Classification System required by ASTM. All mechanical sieving was accomplished with calibrated sieves. Results of the mechanical sieve analysis were used to confirm the soil classification presented in the core logs. In addition, a composite sample was taken for most cores and analyzed for grain size distribution. A split half section of the original core material was preserved for archiving. To ' determine the suitabilityy of sands in the borrow area, individual and composite samples from the vibracores were compared with the grain size distribution of a composite sample from the beach to.be renourished (Beach Model). Thus, the borrow area samples were compared to a beach model compiled. from samples taken along 9 profiles of the Southold Beach. The overfill factor (Ra) and renourishment ratio (Rj) described in the Shore Protection Manual (1984) and described in more detail by James (1975) were used to make the final comparison. Definitions, tables and graphs used in the analysis can be found in Appendix-4. 7 l 4.0 DATA PRESENTATION AND DISCUSSION 4.1 Bathymetry The results of the bathymetric survey are presented on Chart 2 at a scale of 1:6000. 4,Soundings, reduced to NAVD 88, are posted at intervals along the survey tracklines. Bathymetric contour lines at a basic contour interval of five (5) feet are shown with additional contours added at two foot intervals where appropriate. Minimum depths (high points on the seabed) have been added manually from the echo sounder records along each survey trackline. The posted soundings, a small sample of the actual digital soundings file, have been selected to fit the final chart scale. The dominant bathymetric feature is the barrier bar which extends as a wedge- shaped shoal from the western boundary of the study area where it has a width of over 5000 feet pinching out at about 2000 feet NW of Horton Point. Minimum depths on the shoal are 8-9 feet and occur 3000 feet offshore from the present shoreline. The offshore portion of the barrier bar is marked by a very steep slope that approaches 1:10 at some locations. At the base of the slope, the bottom becomes very smooth and slopes very gently to the NW. Maximum depths of over 80 feet are located in the central offshore portions of the survey area. NE of this location, the bottom rises to become much shallower in the NE comer of the area. The NE third of the study area is characterized by a highly ` relieved surface of isolated shoals, mounds and glacial erratics. Figures 3 to 7 illustrate the various topographic features displayed by the echo sounder records. Figure 3 shows the minimum depths encountered crossing the barrier bar, Figure 4 the barrier bar slope. Figure 5 is a section in the relatively flat areas offshore of the bar. Figure 6 shows examples of the high relief bottom encountered in the NE portion of the area. These features appear to be sand waves or underwater dunes which are common in eastern Long Island Sound. In this case, they seem to indicate a transport of sand offshore out of the study area. Figure 7 illustrates the bottom near Horton Point showing the occurrence of glacial erratics lying on the seabed. The potential borrow area lies to the NW of the barrier bar directly offshore Kenney's Beach in water depths of approximately 50 feet. 8 4.0 DATA PRESENTATION AND DISCUSSION 4.1 Bathymetry The results of the bathymetric survey are presented on Chart 2 at a scale of 1:6000.

Sharp spikes on record are assumed to be due to glacial erratics lying on seabed. 4.2 Seismic Survey The subsurface stratigraphy, as determined from the seismic. survey, is presented on Chart 3, Geologic Features and Isopach, and in a series of Plates 1-24 (Appendix 1) which are copies of the subbottom records from each of the vibracore locations. Plate 35 (See Appendix 4) consists of selected whole cross-sections which illustrate the various subsurface features. In constructing the Isopach and affixing a depth scale to the subbottom record, a sound velocity of 5000 feet per second was determined to be a convenient scale that gives good correlation between reflectors and vibracore stratigraphy. The depth scale on all seismic records is 6 msec. per div. (TWT) equivalent to 15 foot depth. The major subbottom reflecting horizon detected in this area is tentatively . identified as being glacial outwash deposit (centerville sand) derived from the bluff moraine deposits. The subsurface portion of this reflecting surface is very flat, even and slopes uniformly in a NW direction at an average gradient of 10' per 1000'. This subbottom horizon outcrops on the seabed along the entire eastern third of the study area opposite Horton Point. Where the glacial outwash outcrops on the surface, it is very irregular with numerous mounds composed of more recent shoal deposits or possibly erosional remnants. Numerous pinnacles are scattered in this area and are interpreted as glacial rock erratics similar to those outcropping on the shore at Horton. (See Photographs of Horton Point at the end of this subsection.) 4.2.1 Glacial Outwash Deposits Examples of the subbottom reflecting horizon which indicates the submerged portion of the glacial outwash surface is shown on Plates 1, 31 5, 6, 7, 8, 9, 17, 18, 19 and 20. The emerged portion where the glacial outwash appears on the seabed is illustrated on Plates 2, 13, 14, 15, 16, 22, 23 and 24. The Seismic Profile of Line 40 on Plate 35 (See Appendix 4) gives an excellent view of both submerged and emerged portions of the glacial outwash surface. On most of these sections, point reflectors -that indicate the presence of glacial erratics can be seen. _Shoals or mounds of more recent sandy deposits lying above the glacial outwash surface are also scattered about the NE part of the area. Examples of these features are shown on Plates 3, 15, 16 and 23. In the NE corner of the area, the shoal deposits are too thick for seismic penetration to reveal the submerged glacial outwash surface. (See Plate 4). 9 4.2.2 Long Island.Sound Marine Deposits Marine deposits of.soft silty-clay lay unconformably above the glacial outwash surface.. Examples of these deposits are shown on Plates 7-and 11 and onProfiles of Lines 3, 14, 17 and 21. Evidence of gassy sediment is shown on Seismic Profile Lines 7 and-17. (See Plate 35, Appendix 4). 4.2.3 Barrier Bar Deposits The shoal deposit that forms the barrier bar is very homogeneous and untextured indicating a thick sequence'of fine sandy sediments. These features are illustrated on Plates 10, 12 and 21 and on profiles of Lines 3, 14, 17 and 21, Plate 35. 10' ''M,}"�-'11° .P,wx..wws^a✓rw 7 -t' � N v r `F n 1 y.n r a• �'C � '�x1 Nr e .r.''

Profile locations are shown on Chart 1, Trackline Chart, and also in Figure 8 for those sample locations used in computing the Beach Model. The profiles shown on Plates 25-34 are diagrammatic only and not intended to be a true representation'of the actual beach profiles. The Beach Model compiled from the,sample data. has a median grain size, MO _ -0.21 Phi, mean grain M� _ -0.44 Phi and a _standard deviation of 1.23.- This median grain size range classifies the average beach material as a Medium sand on the Unified Soil Classification System and as a Very Coarse sand in the Wentworth System. (See Soil Classification Comparison, Appendix 4.) A differential between the median and mean grain sizes is a natural occurrence and it signifies asymmetry in the grain size distribution. Skewness is also a measure of this quality. Only in. those samples that have a normal distribution (random distribution) will the median and mean be equal. ,The mean values are used in the computation of the Overfill Factors (Ra) and Renourishment Factors (Rj) with .the. borrow area sands. The large standard deviation of 1.23 indicates poorly sorted. sands with both appreciable amounts of coarse sands and gravel as well as.finer sand present in the sample. The median, mean and standard deviation values for each sample were considered as separate attributes and assigned a weighting factor which considers the samples position along each profile and distance between profiles. This method of analysis (Polygon method) is similar to those used in assaying mining.prospects. Boundary conditions for the model were Profile 8 and 14 along the beach and the distance between Dune Base samples and Low Water Step samples along each profile. The area covered in the beach model is approximately. 5560' long x 95' average width for an area of approximately 528,200 sq. feet (58,690 sq..yds.). 11 Table 1 Beach Model Profile Sample Mean Median Standard Weighting Mean Median Standard Deviation Factor Component Component Deviation Component 8 Low Water Step -2.09 -1.97 1.74 0.00816 -0.0170544 -0.0160752 0.0141984 Low Water -0.39 0.02 1.33 0.01677 -0.0065403 0.0003354 0.0223041 Mid Beach -1.29 -0.34 2.54 0.02675 -0.0345075 -0:0090950 0.0679450 Upper Beach 0.77 0.81 0.56 0.03234 0.0249018 0.0261954 0.0181104 Berm Crest -0.82 -1.13 1.68 0.02595 -0.0212790 -0.0293235 0.0435960 Dune Base 0.84 0.80 0.46 0.01197 0.0100548 0.0095760 0.0055062 9 Low Water Step -1.19 -1.00 1.71 0.03267 -0.0388773 -0.0326700 0.0558657 Mid Beach 0.41 0.63 0.68 . 0.03267 0.0133947 0.0205821 0.0222156 10 Low Water Step -1.14 -1.15 1.43 0.01690 -0.0192660 -0.0194350 .0.0241670 Mid Beach -0.55 0.08 1.65 0.03556 --0.0195580 0.0028448 0.0586740 Berm Crest 0.31 0.72 1.10 '0.03789 0.0117459 0.0272808 0.0416790 Dune Base 0.87 0.851 0.27 0.01924 0.0167388 0.0163540 0.0051948 12 Low Water Step -0.78 -0.60 1.26 0.01961 -0.0152958 ,-0.0117660 0.0247086 Low Water -0.06 0.09 0.75 0.03432 -0.0020592 0.0030888 0.0257400 Mid Beach -0.93 -0.45 1.74 0.02329 -0.0216597 -0.0104805 0.0405246 Upper Beach 0.10 0.17 0.74 0.01655 0.0016550 0.0028135 0.0122470 Berm Crest -0.36 -0.27 0.95 0.02268 -0.0081648 -0.0061236 0.0215460 Over Berm -1.28 -0.411 0.99 0.01471 -0.0188288 -0.0060311 0.0145629 13 Low Water Step -1.87 -1.64 1.76 - 0.00635 -0.0118745 -0.0104140 0.0111760 Low Water -1.17 -0.81 1.54 0.03059 -0.0357903 -0.0247779 0.0471086 Mid Beach -0.03 0.14 0.83 0.03405 -0.0010215 0.0047670 0.0282615 Upper Beach. -1.61 -1.64 1.10 0.01847 -0.0297367 -0.0302908 0.0203170 .

Out of a group of over 50 samples only those collected along profile 8 to -profile 14 were chosen for comparison to coincide with samples collected for this study: The median grain size in phi units and standard deviation are listed in Table 2 along with their arithmetical averages. The comparison shows that the 1996 samples are some 0.7 phi units finer in median grain size than the current" measurements and the standard deviation shows a much narrower spread of grain sizes. The differences can be attributed to both. the sampling technique and the grain size analysis technique. The 1996 samples were first pre-screened to remove large size cobbles and gravel before being analyzed by..the settling tube method. This shifted the median grain size towards a finer grade and lowered the range of the Standard Deviation. This suggests that the present high Standard Deviation measurement in the 1998 samples are due to the presence of very coarse, sediments. . The 1996 data is useful in the sense that it gives a profile of the coarse to fine sand content on beaches with the gravel sizes removed. However, this data cannot be integrated into the present beach model. 12 Table 2 .

Appendix 3 also includes plots of cumulative percent frequency by dry weight of each sample's grain size distribution, data sheets summarizing the results of sieving analysis, and Penetration graphs. -4.4.1 Vibracore Logs The Vibracore logs are presented on a form similar to US Army Corps of Engineers Form.1836 (Drilling Log Sheet) modified to include information specifically adopted to Vibracores. Core logs contain the physical and initial sedimentological descriptions of the core material at the time the cores were first split. Descriptions were later updated by adding the soil classification after the results of the grain size analysis of the samples were available. Stratification in cores are noted based on visual inspection, change of sediment type or color. Depth positions of various strata were measured . and reduced to elevations below NAVD using tide corrected depths at the . . top . of each core location. The legend follows the- Unified. Soil Classification System coding methods (See copy in Appendix 4.) An average of four (4) samples were obtained from each split core, except core 11 which wasn't sampled. A composite sample was,extracted from each core except cores 11, 7 and 8. These cores contained too much silt (unsuitable material)and were therefore not composited. The composites were madeup of material from the center of the split core taken along its entire length. Commentary: The following are comments and observations concerning the description on some of the cores. SOHD 01 Black Mafic rock layer at 15.4' core depth was a flat glacial erratic lying on the top of a light brown fine sand. This strata correlates perfectly with the glacial outwash deposits. (See Plate 1.) SOHD 02 Vibracore penetrated 19.6 feet but only 17.4 feet was recovered. It is assumed in these cases that either the bottom portion of the core was lost or the vibracore pipe was °pile driving" through the last feet of sediment. 13 SOHD 03 Core stratification shows good correlation to seismic data (See Plate 3.) SOHD 05 Seismic reflector appears at 16' (Plate 5). Glacial outwash corresponds to alternating medium sand, gravel and clay encountered at 15.1 - 16.7 feet. SOHD 06 The multiplicity of stratification in the core is also indicated in the seismic section (Plate 6). SOHD 07 The homogeneous nature of the first 15.5,feet of the core sample is clearly seen in the seismic section (Plate 7). The strong,reflector at 17 feet correlates with the medium sand- coarse gravel encountered at 17.1 feet in the core. SOHD 10 Core 10 shows the.homogeneous fine sands of the barrier bar. Note the uniform texture on the seismic records (Plate 10). SOHD 11 At location 11, the vibracore penetrated under its own weight (no vibration necessary). The bottom sediments consist of organic silt-clays and fine sand and this is obviously unsuitable for beach nourishment purposes; therefore, no further work was done on this, vibracore sample nor were other cores taken in those areas which showed similar bottom conditions. SOHD 16 Core 16 was taken in the area where the Glacial Outwash outcrops on the seabed. Note that the measured. penetration is. 16 feet and the core recovered is 17.2 feet. This condition of over sampling is due to a reorientation of the sand particles from a dense compacted condition to a less dense condition caused by the vibration process. This condition is often met in very dense sands and gravels and -can be anticipated when the penetration rate slows considerably. (See Penetration Graph SOHD 16.) The penetration graph shows that very dense sands were encountered beginning around 12 feet and increased exponentially until.refusal at 16 feet. Since.the sampling depth cannot be greater than the pipe depth, the section below 12 feet is considered expanded. SOHD 18 The brown clay layer in the core beginning at -5.5 feet correlates with a reflector of the same depth in,the seismic 14 section. (Plate 18). These clays are within ,the Glacial Outwash deposits. SOHD 20 The intense stratification in the core sample is borne out by the same intense stratification in the seismic reflection record(Plate 20): 4.4.2 Vibracore Sediment Analysis Data Sheets The data sheets presented in .Appendix 3 give the results of the laboratory grain size testing for each sample. The first column of the data -sheet identifies the sieve sizes (1.5" to 230) used in the series. Columns 2 and 3 give the sizes in mm and Phi units respectively. The remaining columns show the percentage, by dry weight, of samples. passing each sieve size, percent retained and cumulative weights. A statistical analysis was computed from the weight distribution by a graphical method according to Folk. These are stated as 5%, 16%, 50%, 84% and 95% (percentile) and given in-both mm. and Phi units. .From these -values, the Median and Mean grain sizes, Standard Deviation, Skewness and Kurtosis were calculated. . The formulas for calculation of these parameters can be found under Definitions in Appendix 4. 4.4.3 Grain Size.Distribution Graphs Appendix 3 contains the cumulative distribution grain size curves for each sample analyzed on Form NAD 798 in accordance with ASTM standards. Size scales are given for sieve sizes, millimeters (mm) and Phi units, and the median (50%) and quartile.values of 16% and 84% are'identified: The sieve description scale is in accordance with the Unified Soil Classification System definitions. 4.4.4 Penetration Graphs The Alpine Vibracorer is equipped with a penetration device that monitors . the position of the vibracore pipe relative to the coring rig frame. As the vibracore head and pipe travel down the H-Beam support frame, a gear attached to an encoder rotates along a ladder chain at the rate of one revolution per linear foot of translation. The digital signal from the encoder is transmitted to a surface processing unit via RS-232 signal link for both visual display and logging to a 486DX33/8 PC computer using Alpine's proprietary software "Corelog:"- The "Corelog" displays information regarding the amount of core pipe penetration, total coring 15 time, time spent on current foot and time spent coring previous foot. The information is logged in ASCII format along with the time and data, core labels, position and water depth. The penetration graph thus shows a time history of the coring process and is related empirically to the density of the material being cored. Penetration results often reflect .the consistency, degree of compaction, and homogeneity of the bottom sediments. Cores taken in very soft` sediments or in sediments with normal compaction and uniform consistency usually show 'a steep curve with short intervals of time for . each foot of penetration. Examples of this are evident on the penetration graphs of cores 4, 6, 7, 8, 9, 10, 11, 12 (to 10'), 13, 14, 17, 19, 20 (to 10'), 22, 23. and 24. At locations where very compacted sediments are encountered-, -the penetration graph often shows a large peak in the vibration time per foot. Examples of these are at core locations 1, 2 (at 13'), 3 (at 13'); 5 (at 6' - 9'), 10 (at 16' -18'), 15 (at 9' - 16'), 16 (at 12' - - 16'), 20 (at 15'- 19') and 21 (at 7') 16 5.0 QUALITY AND VOLUME OF RECOVERABLE BORROW AREA SANDS 5.1 Compatibility of Area Sediments with Beach Sands and Borrow Area . Selection Criteria Table 3 lists the overfill factors (Ra) and renourishment ratios (Rj)for all samples in comparison to the Beach Model. The overfill factors can be considered an estimate of the volume of borrow material required to produce a unit volume of stable beach material. The overfill factor technique is based on the.assumption that natural sorting processes active on the beach will selectively. remove from the borrow material various undersize classes until a stable grain-size distribution results (James,.-1975). The renourishment ratio is based on the assumption that no borrow sand is completely stable and that a portion of borrow -material will be eroded on an annual basis_depending on the characteristics of its grain-size distribution. The renourishment factor is, therefore, considered the relative volumetric of borrow material required to be replaced 'on an annual basis. Ideally, this factor can be used to establish specific volumetric renourishment requirements. The assumptions and limitations of applying the overfill factor and renourishment ratio techniques are discussed by James (1974, 1975). Of the 24 cores acquired six (6) have been ranked_ in order of their closest fit to the beach model. This ranking is shown in the last column of Table 3 and summarized below. Also indicated is the water depth at the core location and the distance from the core location to the beach at the end of Kenney's Road.- Rank Core Average Water Depth Distance from Beach to end of Kenney's Road 1 6* 51' 3750' 2 23 52' 6000' 3 9* 50, 3700' 4 24* 48' 4500' 5 22 36' 7500, 6 3 61' 9100, * Indicates best choice for borrow area based on the following factors: 1. Best fit to Beach Model with low Ra and Rj factors. 2: Closest proximity to Kenney's Beach with distances around 3700'. 3. Reasonable water depths of 50' allow for economic suction dredging. 4. Excavation at the location of borrow area offshore of barrier bar would not . have any adverse effect on the wave regime impacting the beaches. 17 Commentary on core samples and their Ra and Rj factors. Core SOHD 06 -Ranked No. 1 Core 6 is ranked no. 1 because of the very close comparison of the first 12 feet of core material to the beach. model. The average overfill factor (Ra) is 1.06, which indicates- a suitable match and the renourishment factor averaging 0.2 indicates that this material will erode from the, beach at 1/5 of the present average annual rate. In other words, the sand from this sample would be very stable if placed on the existing beaches. Core SOHD 23 - Ranked No. 2 Core 23 is ranked second because it has a good quality sand below 4.8 feet which continues to the bottom of the core. From 4.8' to almost 20 the overfill factor Ra will average near 1.12 which is quite suitable as a borrow material. Core SOHD 9 - Ranked No. 3 Core 9 is, a very good match with the present beach material with a composite average of Ra=1.15 and Rj=0.15. The very fine grained section of the core would still be very suitable as beach nourishment material. Core SOHD 24 Core 24 is another sample identified as being in the best potential borrow area. Sample No. 3 at 8.0' - 8.3' shows suitable borrow material and this sample represents a depth interval of 4.6 feet to 12.2 feet. 18 .

Rank: Cores are ranked according to closest fit to Beach Model. (M�=-0.44, Md�=-0.21, 8=1.23) 5.2 Volume Estimates Based on the analysis of the sedimentology and stratigraphy of the borrow area, as well as the compatibility of the borrow area samples (cores 6, 9 and 24) with the Beach Model, the area identified and outlined on Chart 3 can be considered potentially suitable and worth further investigation. The borrow area outlined follows the surface trace of a cut and fill channel within the submerged portion of the glacial outwash deposits. Core 24, which anchors the borrow area to the east, shows suitable to marginally suitable material at a depth of 8 feet in the core. This sample is contained within glacial outwash deposits which can be highly variable in size content. The remainder of the outlined area has overburden above the glacial outwash to a maximum thickness of about 10 feet. However, at core location 6, the first 8 feet of sample is a very good match with the present beach model. Core 9 shows a good beach quality sand to a total depth of 17 feet as evidenced by the composite sample results. The area outlined is approximately 250,000 sq. yds. If it is assumed that the probable thicknesp of good material is between 8 feet and 17 feet, the area outlined would yield over 1,000,000 cubic yds..of replenishment sand. If we look conservatively at only the immediate vicinity of core 6 and 9 and confine the borrow area to that bounded by the 5 foot isopach, 200' x 300', the estimated volume is in the order of 277,000 cubic yds. 0 An additional area surrounding Core 23 also has potential for providing suitable fill material. This core location is ranked second in its match to the Beach Model. However, at location 23, there is a possibility of encountering large glacial erratics lying on the seabed close to this position; therefore, the area in the vicinity of Core 23 has not been outlined as a potential borrow area. 5.3 Recommendations for Further Study Before construction is considered, it is highly recommended that additional sampling and survey work be undertaken in the potential borrow areas. . A recommended program of work includes a Side Scan Sonar survey to determine the distribution of glacial erratics or other debris that may lay on the seafloor in close proximity to the borrow area. It is further recommended that additional vibracore samples be obtained in the outlined borrow area and in the vicinity of Core 23 at an approximate grid spacing of 500 feet to better prove the quality and quantity of replenishment sands in these areas. 19 6.0 INLAND SAND SOURCES A total -of seven (7) quarries were" contacted as possible land sources 'for beach nourishment sand. These sources are identified in Table 4 and their locations are indicated on a map of Eastern Long Island, Figure 9. Comments obtained in our interviews with the various companies are given below. 6.1 Inland Survey Summary Coram Materials, source 1. on the quarry location map, is located on Yaphank .Road in Miller Place. This quarry can only offer screened sand at $6 per ton. This price does not include trucking to Southold. A secondary company would have to ship the material to the desired location. East Coast Mines Limited, source.2. on the quarry location map, is located on Lewis Road in East Quogue. This quarry will deliver the Run of the Bank for $7 a ton. Frog Hollow Industries, source 3. on the quarry location map, is located on North Dunton Avenue in Medford. Bank run can be delivered to Southold.for $8.89 per ton. This quarry has previous experience working on beach replenishment projects for the south shore of Long Island. The owner is interested in this project and the price is negotiable. Guillo Construction Corp. located in Southampton (source 4.), can deliver screened sand for$5.93 per ton. This quarry is capable of spreading the sand if requested. A trackloader can be rented for $800 per day, and a payloader may be rented for $1000 per day. Price for spreading machinery includes trained operator and fuel. Hampton Sand Corp., source 5. on the quarry location map, is located on High Street in Speonk. Currently they can deliver screened concrete sand for $8.25 per ton. Bank run which is more suited for the beach in question, can be supplied but a price quote was not offered. Ranco Sand & Stone, Source 6. on the quarry location map, is located on South . Street in Manorville. Bank run can be delivered to Southold for'$8 per ton. Spreading machinery can be rented per day: $1400 for: a D8 Dozer, $200 for a Payloader, $1000 for an off road truck. Price includes operator and fuel. European Express Inc. source 7. on.the quarry location map, is located on Old Northport Road in Kings Park. This quarry can deliver the run of the bank for $11 per ton. 20 6.2 Compatibility of Inland Sand with Beach Sands . Three samples were obtained from the following sources: • East Coast Mines.Ltd. provided us with a grain size distribution curve for their screened sample. • Ranco Sand and Stone -Raw Bank Run Sample • European Express - Raw Bank Run Sample • Guillo Construction Corp. - Screened Sample (Not analyzed) The results of the analysis of three samples compared to the Beach Model is as follows: Sample Mean M� Median Standard Ra Rj Md� Deviation 8 1. East Coast Mines 0.71 0.76 1.11 5.00 2.90 (Screened) 2. Ranco 0.00 0.25 1.88 1.50 0.75 Bank Run. 3. European Express -0.45 0.30 2.48 1.35 0.20 Bank Run 6.3 Cost Analysis The average cost for delivering bank run sand to Kenney's Beach based on sources 2, 3, 6 and 7 is $8.72 per ton or, $6.50 per cubic yard (1 cubic yard = -1.35 tons of dry sand). The estimated cost for spreading the sand on the beach is highly variable and will largely depend on the rate at which sand can be trucked to the site, access roads to the beaches and the number of machines that can be deployed on the beach. A D8 size bulldozer can spread about 2000 cu. yds per day or 2700 tons per day. The maximum trucking loads are 40 tons each. This requires approximately 68 truckloads of sand per working day on site to utilize fully the capacity of one'spreader. Based on a spreading cost that may vary between $0.70/cu. yd. and $1.05/cu. yd., the cost of placing land sand sources on the beach (not.considering environmental factors) is $7.20 per cu. yd. to $7.55 per cu. yd. 6.4 . Environmental Considerations A project of 200,000 cu. yds. in place would require 6,750 truckloads of sand to be carried over the narrow roads leading to Kenney's Beach: Assuming a truck arriving every 5 minutes for 6 hours per day will necessitate a project length of at least 95 working days or 19 weeks. This factor alone will have a significant 21 negative impact on the local residents not to mention the road surfaces leading to the beaches would be destroyed by the heavy truck traffic. In contrast, an offshore dredging operation working around the clock would finish the same job in a fraction of the time as compared to a land operation. 22 Table 4 Inland Survey of Sand and Gravel Quarries Source Description Costrtan Spread Cost/Day Comments 1.

The vessel was launched from the Southold Municipal ramp in Mattatuck. Due-to wind and sea conditions, the survey boat was pulled on February 13th and stored at Matta-Mar Marina. Beach samples were collected on Profiles 6, 8, 10, 12, 13 and 14 at base of dune, berm crest, mid-beach and low water line. On February 18th the survey boat was redeployed and prepared for the survey. A tide gauge was deployed off Goldsmith Inlet on February 19th and the Geophysical Survey`commenced. The geophysical investigation was completed on February 23rd, the subbottom instrument was demobilized and the sampling system installed. The RN Atlantic Twin sailed into the area on February 26th and began taking vibracore samples. The Vibracore operation was completed on March 3rd. The 19' Survey Boat collected bottom samples at inshore trough, rise and sandbar on profile lines 6, 8, 10, 12, 13, and 14 on February 27 and 28. Supplementary beach samples were collected on March 27 .at locations 8, F12, 9, F 17, 12, 13, F21, and 14. The original group of beach samples were split and described at Norwood March 6-12. All grain size analyses were performed by Johnson Soil Laboratory, Ridgefield Park, New Jersey. 8.2 Equipment .8.2.1 Survey Vessels Alpine's 19' Aluminum Vessel with a 140 HP Outboard Motor was outfitted to carry out the Hydrographic Survey and the Sub-bottom Profiler Survey. The vessel.was berthed at the Matta Mar marina during the survey.period. The RN Atlantic Twin, a 90 foot steel catamaran hull research vessel with a 7 foot.draft,ft, was used as the platform for the vibracoring operations. The vessel has ample deck space, anchoring system, hydraulic crane, deck winches and A-frame capability for vibracore operations. The navigational equipment, with associated computer, printer and display 29 unit were mounted in pilot house. The vessel has sleeping facilities to accommodate crew and vibracore staff during the survey.period. 8.2.2 Positioning System A Trimble 4000 Differential GPS Navigation System was used throughout this operation. The DGPS system consists.of an 8-channel satellite receiver . connected to a Starlink USCG HF data link receiver. The Starlink Receiver obtained differential correction signals from the United States Coast Guard GPS transmitter at Sandy Hook, New Jersey and Montauk Point, Long Island New York 8.2.3 Navigation Data Acquisition and Logging System The WGS-84 Geographic positions obtained by the GPS navigation system were converted into New York Long Island Lambert(NAD 83) grid coordinate positions, using a computer and Hypack, navigation software, version 7.1. The system consists of the following components: 1) Computer w/3.5" logging disk 2) Color Video Monitor(Helmsman Display). 3).Hypack v.7.1 software. 8.2.4 Seismic Profiling System The ORE Model 14010KW Transceiver, coupled to a Model 136 Transducer Assembly, mounted over the side of the survey vessel, produced the sub- bottom profiling data which was collected on a EPC 1086 Digital.Recorder and stored through Elics Delphi system on an MO Drive. The subbottom was operated at a frequency of 5000 Hz to,achieve maximum. resolution in the top thirty feet of sediments. 8.2.5 Echosounder . An Innerspace 448 Echosounder, calibrated each day by the "bar check" method,.was used to collect the hydrographic data.. Water depths were reduced to NAVD 88 from data collected on a Coastal Leasing, Inc. "Micxotide Meter"that was deployed off the mouth of Goldsmith's Inlet. 8.2.6 Vibracore A model 271 B Alpine Pneumatic Vibracore configured to take cores 20 feet in length was used on this project. The model.271 B is a self- contained, free standing pneumatic vibracore unit. The unit consists of. 30 an air-driven vibratory hammer assembly; an aluminum H-beam which acts as the vertical guide for the vibrator; a set of four steel support pads and, legs which hold the beam upright on the sea bottom; a steel coring pipe; a cutting edge; 'a core retainer; .a clear PVC core liner; and a penetrometer which records time and depth of penetration of the core pipe into -the seabottom. An air hose array provides passage of compressed air from the compressor on deck to drive the vbracore. Whenever refusal occurred with initial penetration of less than 15 feet, the. sampled portion was removed from the pipe, a new liner inserted, and a jet pump hose was attached just below the vbracore head. The rig was lowered to the bottom and jetted to refusal depth, the jet turned off and Vibrator turned on taking the additional part of the core. 8.2.7 Beach Sampling Offshore. beach samples were collected with a Van Veen grab sampler deployed from the Guppy II. Onshore beach samples, including very shallow water samples, were collected with a post hole digger. 8.3 Personnel .

Figure 11 : Isolines of the renourishment factor, Rj Unified Soil Classification System Soil Classification Comparison Definitions Phi Units (�) Phi Units expresses the grain size as the negative logarithm to base 2 of the grain size diameter in millimeters. � = -1092d, where d = diameter in millimeters Phi � can also be determined by the relationship _ -1092d = - loglo log Median The median is the size either in millimeters (Md) or Phi Units Md� that divides the sample so that half the sample, by weight, has particles coarser than d50 size Mean The mean (M�) as used in this report is calculated by averaging the median and quartile values in the cumulative size distribution. W= $16 + $50 + $84 3 Standard Deviation (a) Standard Deviation is a measure of the degree of sorting (measure of spread) of the size distribution about the mean. Calculated in graphical statistics by: a = 8� 4 - 616 2 Standard Deviation is always a positive number. Small deviations indicate a narrow range of grain sizes (well sorted) while large standard deviations represent a wide distribution of grain sizes (poorly sorted, well graded). The latter attribute is a desirable quality for borrow sand. Skewness (a�) .Skewness (a) is a measure of the degree of asymmetry in the grain size distribution. a� = M� - Md� where M� is the mean, Md� the median and a� the standard deviation. For a perfectly symmetric distribution, the mean equals the median and therefore the skewness equals zero (0). Skewness is a dimensionless number where positive values show bias towards finer grain sizes and negative towards coarser grain sizes. Kurtosis (R�) Kurtosis is a measure of peakness in the size distribution curve and computed from the graphical statistics as follows: (�95 -�Q/2 - 4 . 5� If the distribution is statistically normal the value of P� is 0.65. Lower values indicate a flatter peak indicative of many grain sizes and higher kurtosis indicates well sorted grain sizes. OverFill Factor(Ra) The Overfill Factor (Ra) is an empirical relationship derived by James (1975) that compares the performance of borrow sand material to the natural beach sand. The (Ra) factor number represents an estimate of the volume of borrow sand required to produce the same volume of beach material when the beach is in a condition compatible with the native material (Beach Model). Ra factors are computed from the median (Md�) and standard deviation (8-1�) of the Beach Model and the borrow area samples by use of the graph, Figure 10. Ra.of 1.0 represents a perfect match between borrow area and beach. Renourishment Factor (Rj) Renourishment Factor (Rj) defines an estimate of the ratio of the rate at which borrow material will erode to the rate at which natural beach material (Beach Model) is eroding. Also, an empirical relationship, Rj factors are also computed by reference to the graphs relating the factor to the median sizes and standard . deviations of the borrow material and existing beach material.
