Packet Page -77- 5/8/2012 Item 10.13. n It is estimated that the construction costs for Barefoot, Vanderbilt, Clam Pass, Park Shore and Naples Beaches will be between $16,000,000 - $30,000,000 depending on the project approach, scope and funds available. It is also estimated that the permit design, plans and specifications for this project will cost $400,000 to $600,000. Pre- construction, during construction and post - construction activities are estimated to cost an additional $800,000 and $1,000,000. A preliminary/partial funding request of $600,000 was approved in Fiscal Year 11/12 to begin the permit design and detailed project definition. Additional funding requests will be forthcoming as phased project definition is completed. The estimated construction cost to renourish the South Marco Island Beach and repair the five existing erosion control structures is expected to be $3,000,000. A preliminary/partial funding request of $300,000 was approved in Fiscal Year 11/12 to begin the permit, design and project definition. No additional carrying costs, operating or maintenance costs are expected with approval of the Engineering Services contract. No additional carrying costs, operating or maintenance costs are currently anticipated as a result of the Beach Renourishment project itself. As the design and permitting process advances, the maintenance and lifecycle costs will continue to be evaluated. Using today's dollars, the total cost to replace the asset is $16,000,000 to $30,000,000. The project has an expected life expectancy of 10 years generating a hypothetical annual depreciation cost of $2 to $3 million.

The project included the placement of approximately 176,000 cubic yards of material on the beaches of South Marco Island, and the grading of approximately 8,000 feet of existing beach north of the fill placement. The material was dredged from Caxambas Pass inlet between November 1, 2006 and January 16, 2007, and the grading of existing beach was completed on January 10 -16, 2007 while dredging was in progress. The beach fill spanned approximately 4,400 feet of shoreline beginning at DEP reference monument R -144 south to monument G -2, located approximately 600 feet south of R -148. The beach fill design template had a berm crest elevation of 5.5 feet NGVD, a variable berm width with the narrowest part being the taper at the north end and the widest part north of the Cape Marco Seawall, a 1:100 waterward slope from 5.5 to 4.5 feet NGVD with a maximum width of 100 feet, and a 1:10 foreshore slope starting at an elevation of 4.5 feet NGVD. The borrow area had a maximum dredge depth of -15 feet NGVD with a 2 foot overdepth allowance. Aerial Photouraphs Rectified aerial images dated August 22, 2011 were submitted with this report. Images normally acquired by the Collier County Property Appraisers Office at the beginning of the year are to be submitted to the Department upon availability. Project Performance This report presents the analysis of a monitoring survey conducted by Sea Diversified Inc. (SDI) between December 5t' & 7t', 2011. In general the project is performing well, overall retaining 93% of the post construction volume but erosion continues north of the protection provided by the segmented breakwater. Monitoring section limits for this report were based on the monument range information shown in Tables 1 & 2 below. The shoreline change was measured at the mean high water elevation of +0.44 feet NAVD ( +1.75 feet NGVD) while the volumetric change was determined using an offshore closure depth of -11.8 feet NAVD (-10.5 feet NGVD):' Table 1.

The project area lost an average of almost 35 feet in beach width since the post construction survey, and had an associated volumetric loss of 14,000 cubic yards for the same five -year period. The majority of the erosion occurred in the southern portion of the project area from monuments R -147 to G -1 showing an average decrease in beach width of almost 80 feet and a loss of over 50,000 cubic yards of sand since construction. It should be noted that this change includes post construction readjustment and lateral spreading. Some lateral spreading moved north, and at least in part as a result of this, the northern portion of the project area from R -144 to R -146 increased in width by an average of 10 feet and gained almost 40,000 cubic yards of sand since construction. The accretion to the north may be a compilation of sand migrating south from shoals at the north end of the island as well as lateral redistribution of fill from the project area. The monitoring area at the southern end of Marco Island, bounded on the north by a terminal groin and containing a revetment, from monument G-4 to G-5, has gained an average of 3 feet in beach width, and approximately 4,500 cubic yards of material since the post construction survey. While showing an average decrease in beach width for 2011 of 7 feet, the area gained over 3,000 cubic yards of sand in this monitoring period. It should be noted that this is in the south part of the portion of shoreline which responds to the affects of the segmented breakwater. Kice Island has eroded since the post construction survey showing losses of approximately 67,000 cubic yards since 2007, and over 14,000 cubic yards during this most recent monitoring period. The conditions of the shoals, which have been shown to be valuable shorebird habitat, within the Caxambas Pass area were quantified based on the emergent area estimated from the rectified aerial images. There was a decrease in emergent area of over 3 acres, from 7.8 acres in 2007 to 4.5 acres in 2011. Over the entire five -year monitoring period the area has experienced both of accretion & erosion in part due to the effects of the Tropical Storm Faye in 2008, and the migration of the shoals in the five years since project construction. Recommendations for Proiect Management and Strategic Beach Management Piannina Project monitoring and reporting should continue in accordance with the approved monitoring plan and specific conditions of the permit. 2 Packet Page -81- 5/8/2012 Item 10.6.

This report presents the analysis of a monitoring survey, conducted in December of 2011. This is the fifth monitoring survey to be conducted subsequent to the January 2007 beach renourishment project. The survey was conducted by Sea Diversified Inc. (SDI) between December 5"' & 7h, 2011 based on the requirements of the State of Florida Department of Environmental Protection (DEP) permit number 0235209 - 001 -JC dated December 22, 2005, U.S. Army Corps of Engineers permit number SAJ- 2005 -2726 (IP -MN) issued January 6, 2006, and the approved Monitoring Plan revised by Taylor Engineering, Inc. dated December 2, 2004 included in Appendix A. A permit modification 0235209- 002 -EM was issued to Collier County on December 27, 2006 to include grading of existing beach north of the project area from DEP reference monuments R -139 to R -144. South Marco Island and Caxambas Pass are located in Collier County on the southwest coast of Florida as shown in Figure 1. The monitoring area includes DEP reference monuments R- 144 south to G -5 on the northern side of Caxambas Pass, and K -1 & K -2 south of the pass on Kice Island. The project included the placement of approximately 176,000 cubic yards of material on the n beaches of South Marco Island, and the grading of approximately 8,000 feet of existing beach north of the fill placement. The material was dredged from Caxambas Pass inlet between November 1, 2006 and January 16, 2007, and the grading of existing beach was completed between January 10 -16, 2007 while dredging was in progress. BACKGROUND • 1991 Beach restoration project placed approximately 575,000 cubic yards of sand on the beach and included the construction of two terminal rock groins. • 1996 The construction of a segmented breakwater, consisting of three segments to reduce sand losses into Caxambas Pass. • 1997 South Marco Beach Nourishment placed approximately 60,000 cubic yards of sand on the beach from Caxambas Pass. Minor amounts of sand were brought by truck in '98 &'99. • 2007- January South Marco Island Beach Nourishment Project • 2007- January Post construction survey by SDI • 2008 - August Tropical Storm Fay passes to the south. • 2008 - September Monitoring survey conducted by SDI • 2009 - December Three -Year Monitoring survey conducted by Coastal Planning & Engineering, Inc.

DESIGN PLAN Figure 2 is an aerial exhibit showing the project extents and monitoring area from DEP reference monument R -139 south to monument K -2 on Kice island. The figure shows the extent of the fill, limits of the beach grading conducted under the permit modification, and the borrow area. The scope of the monitoring survey data collection and horizontal control for the survey are also shown in Figure 2. The beach fill spans approximately 4,400 feet of shoreline beginning at DEP reference monument R -144 south to monument G -2 (The G -2 profile azimuth is outside of the fill template) located approximately 600 feet south of R -148. The beach fill design template had a berm crest elevation of 5.5 feet NGVD, a variable berm width with the narrowest part being the taper at the north end and the widest part north of the Cape Marco seawall, a 1:100 waterward slope from 5.5 to 4.5 feet NGVD with a maximum width of 100 feet, and a 1:10 foreshore slope starting at an elevation of 4.5 feet NGVD. The borrow area had a maximum dredge depth of -15 'NGVD with a 2 foot overdepth allowance. MONITORING SURVEY DATA The analysis in this monitoring report is based on data from the surveys listed below. Note the four -year monitoring survey is comprised of three different surveys conducted on different dates including Caxambas Pass and the borrow area. The borrow area survey is to be conducted at two -year intervals as described in the monitoring plan attached as Appendix A, and therefore was not included in the scope for this monitoring event. • Pre dredging beach survey conducted on October 27, 2006 by SDI • Post dredging beach survey conducted on January 29, 2007 by SDI • Four -year monitoring survey conducted in January 2011 • Monuments R -140 through R -148 by M &E on 12/17/2010 • Monuments G -1 through G -5 by CEC on 1/1912011 • Monument R -139, K -1 & K -2 by M &E on 6/29/2011 • Caxambas Pass & Borrow Area by M &E on 12/17/2010 • Five -year monitoring survey conducted in December 2011 by SDI The beach profile cross sections for these surveys are shown in Appendix B. The survey data for this monitoring period is in DEP & xyz format on the DVD submitted with this report and the surveyor's certification is attached as Appendix C. VOLUME &SHORELINE CHANGE Monitoring section limits for this report were based on the monument range information provided in Table 1 below. The shoreline change was measured at the mean high water elevation of +0.44 feet NAVD ( +1.75 feet NGVD) while the volumetric change was determined using an offshore closure depth of -11.8 feet NAVD ( -10.5 feet NGVD).' The limits of the volumetric analysis shown as the "Distance from Mon." (Distance from Monument) in Tables 2 & 3 were determined by the intersection of the 2011 beach profile and the -11.8 feet NAVD depth of closure. ' -11.8 feet NAVD depth of closure used to maintain consistency with previous monitoring reports. 3 Packet Page -85- C tY �Iy HUNUSTON & MW IRE FNGMER!

Some lateral spreading moved 6 Packet Page -88- 5/8/2012 Item 10.B. north, and at least in part as a result of this, the northern portion of the project area from R -144 to R -146 increased in width by an average of 10 feet and gained almost 40,000 cubic yards of n sand since construction. In this most recent monitoring period erosion occurred from DEP Monument R -145 to R -147 with the majority of the erosion at the southern monuments R -146 & R -147. This section of the project area shows an average decrease in beach width of 6 feet, and the loss of over 15,000 cubic yards of sand in 2011. The shaded area in Figure 3 represents the shoreline change within the project area, and a comparison of changes at different monitoring intervals. Figure 4b (Page 9) shows the change in the mean high water line since the preconstruction survey. The entire project area from R- 144 south to monument G -1 showed an increase in average beach width, gaining 2 feet in this monitoring period, while at the same time there was a loss of approximately 11,000 cubic yards due to changes in profile shape and sand losses seaward of the mean high water line. South of the Project Area (G -2 through G-5) This portion of the monitoring area, bounded on the north by a groin and containing an exposed revetment, from monument G-4 to G -5, has gained an average of 3 feet in beach width, and approximately 4,500 cubic yards of material since the post construction survey. While showing an average decrease in beach width for 2011 of 7 feet, the area gained over 3,000 cubic yards of sand in this monitoring period. It should be noted that this is in the south part of the portion of shoreline which responds to the affects of the segmented breakwater. Kice Island (K -1 & K -2) Kice Island is located south of Caxambas Pass as shown Figure 2. No shoreline change was n noted at Station K -1 in 2006 and 2007 due to the lack of emergent land; however the area lost over 50 feet of beach at Station K -1 in 2011. Station K -2 shows a decrease in beach width since 2007 of over 25 feet, but an increase of 5 feet in 2011. The area has eroded since the post construction survey showing losses of approximately 67,000 cubic yards since 2007, and over 14,000 cubic yards during this most recant monitoring period. Most of this volumetric loss occurs in the nearshore shoal area. Figure 4c (Page 10) shows the changes -in the mean high water line, as estimated from the rectified aerial images, from the immediate post construction condition to August 2011, as well as the changes in the nearshore shoal region. Figure 4c (Page 10) also shows the condition of the shoals, which have been shown to be valuable shorebird habitat, within the Caxambas Pass area. The emergent area of shoal was estimated from the rectified aerial images. There was a decrease in emergent area of over 3 acres, from 7.8 acres in 2007 to 4.5 acres in 2011. AERIAL PHOTOGRAPHS Rectified aerial images dated August 22, 2011 are included on the DVD contained in this report. Images normally acquired by the Collier County Property Appraisers Office at the beginning of the year will be submitted to the Department upon availability.

CONCLUSIONS & RECOMMENDATIONS The portion of the monitoring survey located on Marco Island showed significant increases in /0-111 both shoreline and volume change since the project was constructed five years ago. The majority of the accretion occurred in the northern portion of the monitoring area including the northernmost stations within the beach fill limits. Losses occurred in the southern portion of the beach fill area mainly at monuments R -145 through R -147 north of the area protected by the segmented breakwater. Although the beach south of the project area in lee of the structures shows a loss in beach width in 2011, there was an associated volumetric gain for the same period. This illustrates that the structures add some stability to the beach, yet allow the beach to respond to natural littoral processes. Kice Island and the shoals in the highly dynamic Caxambas Pass area have undergone significant change since the project was constructed as evidenced in the aerial photographs shown in Figure 4c, and the shoreline change noted at monuments K -1 and K -2. Over the entire monitoring period the area has experienced both of accretion and erosion in part due to the effects of the Tropical Storm Faye in 2008, and the migration of the shoals in the five years since project construction. The project area has lost approximately 14,000 cubic yards of sand since construction, and over 11,000 cubic yards in 2011, however the beaches both north and south of project area show accretion since construction. The majority of the accretion is distributed in the northern half of the monitoring area as shown in Figure 5. This figure shows the post construction volume in comparison to the volume remaining in December 2011 for the entire monitoring area with the project area shaded in gray. The accretion to the north may be a compilation of sand migrating south from shoals at the north end of the island as well as lateral redistribution of fill from the project area. Figure 6.

PHYSICAL MONITORING PLAN FOR THE SOUTH MARCO ISLAND BEACH RENOURISHMENT PROJECT Pursuant to 62B- 41.005(16), F.A.C., physical monitoring of the project is required through acquisition of project - specific data to include, at a minimum, topographic and bathymetric surveys of the beach, offshore, and borrow site areas, aerial photography, and engineering analysis. The monitoring data is necessary in order for both the project sponsor and the Department to regularly observe and assess, with quantitative measurements, the performance of the project, any adverse effects that have occurred, and the need for any adjustments, modifications, or mitigative response to the project. The scientific monitoring process also provides the project sponsor and the Department information necessary to plan, design, and optimize subsequent follow -up projects, potentially reducing the need for and costs of unnecessary work, as well as potentially reducing any environmental impacts that may have occurred or be expected. The physical monitoring plan that follows satisfies this requirement for the South Marco Island Beach Renourishment Project. If future revision of this plan becomes necessary, Taylor Engineering will, by written request, notify the Florida Department of Environmental Protection (FDEP). The South Marco Island Beach Renourishment Project area extends from R -144 to G-2 at the northern terminal groin, approximately 600 ft south of R 148. The physical monitoring control area extends 5,217 ft north of the project area b monument R-139 and extends 505 ft south to the southern terminal groin adjacent to Caxambas Pass. The northern control area incorporates monuments R-139 to R -143, and the southern control area incorporates monuments G -3 to G-5. An additional control area includes profiles Kl and K2 on Kice Island downdrift of Caxambas Pass to observe potential effects of the borrow site on the downdrift shoreline. Topographic and Bathymetric Surveys Beach and Offshore Area The primary monitoring area, which includes the project (R -144 to R-148, G I to G2) and the control areas (R -139 to R-143 and G3 to GS), will consist of profile surveys every monument for a total of 15 profiles. The secondary monitoring area includes 2 additional profiles, K -1 and K -2 on Kice Island. Packet Page -98- 5/8/2012 Item 103. Topographic and bathymetric profile surveys of the beach and offshore shall be conducted within 90 days prior to commencement of construction, and within 60 days following completion of construction of the project. Thereafter, monitoring surveys shall be conducted annually for a period of three (3) years, then biennially until the next beach nourishment event or the expiration of the project design life, whichever occurs first. The monitoring surveys shall be conducted during a spring or summer month and repeated as close as practicable during that same month of the year. If the time period between the immediate post- construction survey and the first annual monitoring survey is less than six months, then the permittee may request a postponement of the first monitoring survey until the following spring/summer. A prior design survey of the beach and offshore may be submitted for the pre - construction survey if consistent with the other requirements of this condition. All work activities and deliverables Mall be conducted in accordance with the latest update of the Bureau of Beaches and Coastal Systems (BBCS), Monitoring Standards for Beach Erosion Control Projects, Section 01000 -Beach Profile Topographic Surveying and Section 01100 - Offshore Profile Topographic Surveying. Borrow Area A hydrographic survey of the Caxambas Pass borrow area will be performed. The survey shall be bounded in the east -west direction by the inlet throat and the offshore 15 -ft water depth contour and bounded in the north -south direction by the Marco Island south end seawall and transect K1 on Kice Island. The northern half of the survey domain will be surveyed north -south at 200 -ft line intervals, the southern half of the domain will be surveyed north -south at 400-ft line intervals, and the entire domain will have east -west lines at 600-ft intervals. We defined a high resolution for the northern half of the survey domain so that the survey may be used to prepare project plans if Caxambas Pass needs dredging in the near future. Bathymetric surveys of the borrow area shall be conducted within 90 days prior to commencement of construction, and within 60 days following completion of construction of the project concurrently with the beach and offshore surveys required above. Thereafter, monitoring surveys shall be conducted at two (2) year intervals concurrently with the beach and offshore surveys required above. A prior design survey of the borrow area may be submitted for the pre- Packet Page -99- 5/8/2012 Item 10.B. construction survey if consistent with the other requirements of this condition. Work activities and deliverables shall be consistent with the BBCS Monitoring Standards for Beach Erosion Control Projects, Section 01200 - Borrow Site, Shoal and Other Bathymetric Aerial Photography Aerial photography of the beach shall be taken concurrently with the post - construction survey and each annual and biennial monitoring survey required above, as close to the date of the beach profile surveys as possible. The Iimits of the photography shall include the surveyed monioring area as described above. All work activities and deliverables shall be conducted in accordance with the latest update of the BBCS Monitoring Standards for Beach Erosion Control Projects, Section 02000 - Aerial Photography. Report The permittee shall submit an engineering report and the monitoring data to the BBCS within 90 days following completion of the post- construction survey and each annual or biennial monitoring survey. The report shall summarize and discuss the data, the performance of the beach fill project, and identify erosion and accretion patterns within the monitored area. in addition, the report shall include a comparative review of project performance to performance expectations and identification of adverse impacts attributable to the project. Appendices shall include plots of survey profiles and graphical representations of volumetric and shoreline position changes for the monitoring area. Results shall be analyzed for patterns, trends, or changes between annual surveys and cumulatively since project construction. Monitoring reports and data shall be submitted to the Bureau of Beaches and Coastal Systems in Tallahassee. Failure to submit reports and data in a timely manner constitutes grounds for revocation of the permit. Any monitoring information submittal to the Bureau shall include a transmittal cover letter clearly labeled with the following at the top of each page: "This monitoring information is submitted in accordance with Item No. [XX] of the approved Monitoring Plan for Permit No. 0235209 -001 -JC for the monitoring period [XX]. Packet Page -100- 5/8/2012 Item 10.B. BIOLOGICAL MONITORING PLAN FOR THE SOUTH MARCO ISLAND BEACH RENOURISHMENT PROJECT The Florida Department of Environmental Protection (FDEP) requires the submittal of a detailed monitoring plan for any proposed beach nourishment project. The biological monitoring plan that follows satisfies this requirement for the South Marco Island Beach Renourishment Project. The plan addresses beach compaction, scarp formation, turbidity levels, and marine turtles. Sediment Compaction Monitoring During the three years following fill placement, the permittee will measure sand compaction in the area of restoration in accordance with the protocol described below. Compaction testing, performed before the marine turtle- nesting season, determines whether the beach requires tilling. If the beach is tilled before May 1, no measurement of sediment compaction is required. An annual summary of compaction surveys and the actions taken shall be submitted to the FDEP. Compaction sampling stations shall be located along shore perpendicular transects spaced 500 ft apart along the project area. Three sampling stations — positioned at the dune toe, mid - berm, and MHW shoreline — shall be located along each transect. At each station, the cone penetrometer shall be pushed to a depth of 6, 12, and 18 inches three times (three replicates). Material may be removed from the hole if necessary to ensure accurate readings of successive levels of sediment. The penetrometer may need to be reset between pushes, especially if sediment layering exists. Layers of highly compact material may Jay over less compact layers. Replicates shall be located as close to each other as possible, without interacting with the previous hole and/or disturbed sediments. The three replicate compaction values for each depth shall be averaged to produce final values for each depth at each station. Reports shall include all 27 values for each transect line, and the final 9 averaged compaction values. If the average value for any depth exceeds 500 psi for any two or more adjacent stations, then that area shall be tilled before Mav 1. If values exceeding 500 psi are distributed throughout the project area but in no case do those values exist at two adjacent stations at the same depth, Packet Page -101- 5/8/2012 Item 10.B. then consultation with the FDEP shall be required to determine whether tilling is required. If a few values exceeding 500 psi are distributed randomly within the project area, tilling shall not be required. Scarp Monitoring Visual surveys for escarpments along the beach fill area shall be made immediately after completion of the beach nourishment project and before May 1 for the following three years if placed sand remains on the beach. In addition, weekly surveys of the project area shall be conducted during the two nesting seasons following completion of fill placement as follows: The number of escarpments and their location relative to FDEP reference monuments shall be recorded during each weekly survey and reported relative to the length of the beach surveyed (e.g., 50% scarps). Notations on the height of these escarpments shall be included (0 to 18" and greater than 18 ") as well the maximum height of all escarpments. Escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a distance of 100 ft shall be leveled to the natural beach contour by May 1. Any escarpment removal shall be reported relative to R- monuments. If weekly surveys during the marine turtle nesting season document subsequent reformation of escarpments that exceed 18 inches in height for a distance of 100 ft, the FDEP shall be contacted immediately to determine the appropriate action to be taken. Turbidity Monitoring Turbidity monitoring, performed during construction in the vicinity of the borrow site and beach disposal area, will occur at background and compliance locations. The following discusses methods to monitor the borrow site and beach disposal area as required by the permit. Borrow Site Frequency: Every six hours during dredging. Packet Page -102- 5/8/2012 Item 10.B Location: Background: One meter below the surface and one meter above the bottom, at least 300 meters up current from the dredge site, clearly outside of any turbidity generated by the project. Compliance: One meter below the surface and one meter above the bottom, no more than 150 meters down current from the dredge site, within the most dense portion of any visible turbidity plume. Beach Disposal Area: Frequency: Every six hours during pumping operations. Location: Background: Mid- depth, at a point approximately 150 meters offshore and 1,000 meters up current from the discharge point, clearly outside of any turbidity generated by the project or coming from the inlet. Compliance: Mid - depth, at a point approximately 150 meters off shore and no n more than 150 meters down current from the discharge point, within the densest portion of any visible turbidity plume. These locations may change if a mixing zone variance is granted. Turbidity monitoring data, submitted to the Bureau of Beaches and Wetland Resources and to the Northwest District Office within one week of collection, will consist of the following information: (1) permit number, (2) "South Marco Island Beach Renourishment Project "; (3) dates and times of sampling and analysis; (4) a statement describing the methods used in collection, handling, storage and analysis of the samples; (5) a map indicating the sampling locations, current direction, plume configuration and the location of the dredge and discharge point(s); and (6) a statement by the individual responsible for implementation of the sampling program concerning the authenticity, precision, limits of detection and accuracy of the data. Monitoring reports shall also include the following information for each sample that is taken: (a) time of day samples taken; (b) depth of water body; (c) depth of sample; (d) antecedent weather conditions; (e) tidal stage and direction of flow; (f) wind direction and velocity; and (g) DGPS position. Packet Page -103- 5/8/2012 Item 10.13. Marine Turtle Nest Monitoring The proposed South Marco Island Beach Renourishment Project may require construction during the sea turtle nesting season. A marine turtle monitoring plan is outlined below. Onshore Monitoring A daily marine turtle nest survey of the nesting beach in the vicinity of the project (including areas of beach access) shall be conducted starting May 1 and continue until October 31. Nests potentially affected by construction activities shall be relocated. Nests requiring relocation shall be moved no later than 9 a.m. the morning following deposition to a nearby self - release beach site in a secure setting where artificial lighting will not interfere with hatchling orientation. Nest relocations, in association with construction activities, shall cease when construction activities no longer threaten nests. Nests deposited within areas where construction activities have ceased or will not occur for 65 days shall be marked and left in place unless other factors threaten the success of the nest. Such nests will be marked and the actual location of the clutch determined. A circle with a radius of ten (10) ft, centered at the clutch, shall be marked by stake and survey tape or string. No construction activities shall enter this circle. No adjacent construction will begin which might directly or indirectly disturb the area within the staked circle. All nesting survey and nest relocation activities shall be conducted only by persons with prior experience and training in these activities and who are duly authorized to conduct such activities through a valid permit issued by the Florida Fish and Wildlife Conservation Commission (FWC), pursuant to Florida Administrative Code 6$E -1. In the event a sea turtle nest is excavated during construction activities, all work shall cease in that area immediately and the permitted person responsible for egg relocation for the project should be notified so the eggs can be moved to a suitable relocation site. Marine turtle nest monitoring shall continue after construction is complete. Reports on all nesting activity shall be provided for the initial nesting season and for a minimum of two additional nesting seasons. Monitoring of nesting activity in the three seasons following Packet Page -104- 5/8/2012 Item 10.B. construction shall include daily surveys and any additional measures authorized by the FDEP. Reports submitted shall include daily report sheets noting all activity, nesting success rates, hatching success of all relocated nests, hatching success of a representative sampling of nests left in place (if any), dates of construction, and names of all personnel involved in nest surveys and relocation activities. Monitoring shall occur in the project area and equal length of adjacent non- filled beach. Data will be reported separately for filled areas and non -filled areas in accordance with Table 1. Surveyors, upon locating a dead, injured, or sick endangered or threatened sea turtle specimen, must notify the FDEP. Care should be taken in handling sick or injured specimens to ensure effective treatment and care and in handling dead specimens to preserve biological materials in the best possible state for later analysis of cause of death. In conjunction with the care of sick or injured endangered or threatened species or preservation of biological materials from a dead animal, the finder has the responsibility to ensure that evidence intrinsic to the specimen is not disturbed. Following marine turtle nesting season, a report summarizing turtle nesting within the n beach construction area shall provide data to assess emergences, nests, and reproductive success /failure in the beach construction area. Nesting data, submitted to the FDEP, will include separate reports, one for filled beaches and one for non - filled beaches, and shall include numbers of nests lost to erosion or wash out. Table 1 provides the appropriate format and required data for reporting nest data to FDEP. Packet Page -105- 5/812012 Item 10.13. Table 1 Table Format and required Data for Reporting Marine Turtle Nesting Data Characteristic Parameter Measurement Variable Nesting success False crawls Visual assessment of all false crawls Number and location of false crawls in fill areas and non -fill areas: any number interaction of the turtle with obstructions, such as groins, seawalls, or scarps, should be noted. False crawl Categorization of the Number in each of the following type stage at which nesting categories: emergence -no digging, was abandoned preliminary body pit, abandoned egg chamber Nests Number The number of marine turtle nests in filled and non - filled areas should be noted. If possible, the location of all marine turtle nests shall be marked on map of project, and approximate distance to sea walls or scarps measured using a meter tape (optional). Any abnormal cavity morphologies should be reported as well as whether turtle touched groins, seawalls, or scarps during nest excavation Lost nests Number The number of nests lost to inundation, erosion or the number with lost markers that could not be found Reproductive Emergence Standard survey Numbers of the following: unhatched success & hatching success protocol eggs, depredated nests and eggs, live pipped eggs, dead pipped eggs, live hatchlings in nest, dead hatchlings in nest, hatchlings emerged, disoriented hatchlings. depredated hatchlings, Packet Page -106- 5/8/2012 Item 10.B.

(SDI Project Number 11 -1882) December 5, 2011 through December 7, 2011 5/8/2012 Item 10.B. - 46,10 Lipscomb Street, Suite 12 Palm Bay, Florida 32905 Phone: 321- 984 -7268 Facsimile: 321- 984 -7270 Survey Scope: Beach Monitoring Profiles R -138 through R -148, GI through G5 and K -1 and K -2 (Kice Island), Marco Island, Collier County, Florida. Notes: 1. This survey report was prepared to accompany the digital data files (ASCII X,Y,Z) submitted to Humiston and Moore Engineers that were acquired as part of the South Marco Island, Beach Monitoring Survey. In addition to the XYZ data files SDI has included digital photographs of each profile (N, S, E, and W), scanned field notes, meta -data file and profile and survey control spreadsheet ( *.xls). The survey encompassed upland topographic and offshore bathymetric profile data collection of (17) historic beach monitoring lines R-138 through R 148, GI through G5 and K -1 and K -2. This survey report is not valid without the signature and the original raised seal of a Florida Licensed Surveyor and Mapper. 2. All field data collection activities meet or exceed the Minimum Technical Standards set forth by the Florida Board of Professional Surveyors and Mappers in Chapter 5J -17, Florida Administrative Code, pursuant to Section 472.027, Florida Statutes. 3. The information depicted herein represents the results of the survey on the dates indicated and can only be considered as indicating the general conditions existing at the time. 4. Horizontal data are in feet relative to the Florida State Plane Coordinate System based on the Transverse Mercator Projection for Florida, East Zone (0901), North American Datum (NAD) of 1983, 1990 Adjustment. Vertical data are in feet relative to the North American Vertical Datum of 1988 (NAVD 88). S. Bathymetric data was collected using a Trimble Real -time Differential Global Positioning System (DGPS) for positioning and an Odom model "Hydrotrac" sounder, using a 200kHz narrow beam (3°) transducer. In order to minimize motion induced by wave action a TSS model "DMS -05 ", 3 -axis motion sensor was used. Differential corrections were acquired from the U.S. Coast Guard Navigation Beacon System. Horizontal position accuracy was verified using published profile control points. The sounder was calibrated prior to the start of the survey following manufacturer recommended procedures. 6.
