These studies represent the first step in the implementation of the Coun'.y s Beach Preservation Plan. In order to accomplish this objective, the ATM Project Team proposes a technical approach that accomplishes: 4 per'formsnou of an affsho,•c geotechraii:di investigation to locate suitable quantity and quality sands for county -wide beach restoration efforts; mapping, characterization and impact assessment of the hardbottom resources which are present in the nearshofe zone of the County coastline from Sebastian Inlet State Park to Wabasso Beach, Vero Beach and South County Beaches. and, ♦ preparation of the Beach Restoration Pian. Design and Cost Estimate Report describing the findings of the geotechnical and hardtsotlom mapping studies, analyzing the technical and environmental feesitidity of acquiring Project permits and developing design beachfill templates and cost estimates of suf nt detail to supt,orl submitting permit applications to the State and Federal agencies Identifying the extent and quality of offshore sand resources and characterizing the types (ephemeral, worm -rock, etc) and pry kacmItions of the near shore hardbottom resources are critical to optimizing the deaV iW fecfdttaitirnq permitting of the beach nourishment Projects for Beach Sectors 1 & 2, 3. 5 and 7. The sand source investrgab ns will be performed by ATM coastal enguneers working onsite mh the prinwcipal inveetigato,rs from SEA, MEI and OEI. Similarly, the hardbottom mapping and charactenzabon investigations will be managed by ATM with the principal investigators from CSAf The final report, maps, coastal engineering design and environmental evaluations and design studies will be performed by ATM in-house. ATM will work in chose cooperation with Indian River County Staff as well as Florida Department of Environmental Protection officials to expedite field, laboratory and office components of the work wtute providing the County with the highest level of terwee The Project Scope of Services and tasking are presented in the Technical Approach that follows, Task 1: County -wide Geolochni+cal Investigation of Offshore Sand Resourcea Task 1,1 ReyLe 4nic and Phvsical Data Few studies exist that specifically targeted the distribution of offshore sand resources in Indian River County. A brief review of the existing body of information known at this time is presented below. In addition to those reports summarized below, County files will be reviewed to ensure that all known existing geotechnical information and data have been acquired for consideration by the Project Team, The U.S. Array Carps of Engineers Coastal Engineering Research Center Technical Memorandum Number 34, published in February 1971 and titled "Geomorphology and Sediments of the Inner Continental Shelf: Palm Beach to Cape Kennedy, Florida" (Meisburger and Duane, 1971), provides a comprehensive review of sediments investigated offshore of Indian River County as part of the Inner Continental Shelf Sediment and Structure Program (ICONS). In particular, this document provides an indication of a comprehensive investigation of an area referred to as the f=ort Pierce Grid, which includes extensive survey Iracklines and vibracores offshore of the southern half of the Indian River County shoreline. Field work in association with the ICONS study was undertaken between ,January and May 1965. Several large-scale shoal features are identified in the report, the most notable of which was referred to as the Indian River Shoal. Bethel Shoal is located contiguous to Indian River County waters, but is located in 9r3Sdmr�Urc o -p desipalprgeG cnsi.K,^SCOP[ Of WORK N2999M Technical Appronch Page 2 federal waters, and "I"nomas Shoal, also located beyond the three-mile jurisdictional limit, was dcamed to contain 'fair" quality sand. Eased on a single vibracore and seismic data, estimates from CERC were that the "volume of usable sand in middle Indian River Shoat is 10.3 x 1Cgcubic yards,' Scientific Environmental Applications, Inc., has acquired and analyzed the vibracore samples and seismic records collected for the iCONS investigation of the Fort Pierce Grid, and has developed a preliminary contour map of mud layers offshore of the southern half of the County which will be reviewed and analyzed prior to developing the final offshore areas for jet probes and vibracore exploration. Additional review of the records and tracts line date will be conducted to refine the field investigations in the vicinity of Indian River Shoal in an attempt to isolate the highest quality sands contained it i this otherwise limited sand resource segment of offshore waters. In August 1980, the U.S. Army Corps of Engineers WSACE) Jacksonville District cofopleted a "Feasibility Report for Beach Erosion Control — Indian River County Baachrs," Project recommendations included beach restoration Project initiatives for the Sebastian Inlet State Recreation Area and Vero Beach. The District obtained a total of 55 vibracores between approximately 3,000 and 4,000 feet offshore of Indian River County in May 1973 and May 1974. These togs and grain size distribution (GSD) Information were requested and have beer) Sent to ATM. The USACE concluded that there were two potential borrow areas and one 'passible' site. ATM will review this data and assess the validity of this information. If available, ATM will perform a site inspection of these cores M the USACE depot to assess sand quality and review the precise location of each of the cores, This data will be compiled and analyzed in developing the field investigation work pram. The document 'Beach Eroslon Control indian River County, Florid8 {USACE, (ktober 1987) contains reference to addliliional sixteen vibracores obtained in late IgUlearly 1985 to better delineate the offshore barrow souse considered in the 1980 study. The core logs and grain We distribution Ctrrtln prwr ded in this effort wril be carefully revie%red, as will all other prior geoterchnnkkeb and eirvVirinawnlal study efforts conducted in Indian River County. in addition, ATM wig nw*w data and information srxrrces dest:nbed in the 1988 Cubit Engineering, Ltd, report 'Beach Preservation Plan far Indian River County, Florida' which summarizes sand source tnvmtigalrana undertaken at the time of the report preparation ATM will review previously acqurred USACE vibnxxwes And widependertif trampling to determine optilTial borfnw area geometries and a selective dredging plan desoVied in Ilia CPE (1989) 'City of Verna Beach Restoration PrtT}ect Assessment Report While the cores revealed excessive fine-grained r'naf nal percentagtrs, ATM will review the data to determine if the site warrants furlhef Wivestlpation for the vibracore study to be undertaken by the Project Team. Task 1.2 Identify OHshvre larget PnQylies and!Can0i4te Areas flit in Eigalion This task will develop a fiend 'investigation plan for the preliminary phase of the geotechnical investigation to identify and rank high probability sand sources. These areas will be determined by synthesizing prior report data (surtirrnanzed above), bathymetric data indicative of potential shoat feature(s), proximity to the Project segments to be nourished, and location relative to federal jurisdiction inside the Three Nautical Mile trine. While there appear to be considerable sand reserves in federal waters, efforts for this study will principally be concentrated in State waters. As the ICONS study collected only 'reconnaissance -level' data and information in the north half of the County, the proximity of even moderate amounts of surficial beach -quality sands to the identified Project initiatives in Sectors 1, 2 and 3 warrants consideration of additional investigation of the north half of the County offshore areas. Following a complete synthesis of all existing bathymetric and geophysical data, a plan view graphic(s) of the Indian River County offshore area will be prepared to guide decision-making for jet probes, vibracores and side scan sonar mapping areas (Task 1.3, described below). ATM will work with Dr. Gary Zarillo, P.G. and Maryann Civil, P.G. of SEA, Inc. in defining the locations to conduct core borings and bathymetric data collection targeting of the search area(s) of highest potential.

Siesmic data will be collected only if warranted based Oil I/W fifidings of the jet ,probe or vibracore studies. If required, survey €racklines to establish a coverage 'grid' of high ,potential candidate areas will be established which will utilize maximurn slant range on the seismicyside scan unit in order to maximize daily coverage areas (at an additional cost not to exceed $ 10, 000). Task 1.3 Perform ,let Probes at Candidate Borrow Areas A jet probe investigation of target areas identified in Task 1.2 will be performed to determine the depths to rock and the characteristics of the overlying strata. Sand samples will be collected at each probe site to examine the sand characteristics and to confirm/validate the previously collected core "GSD" data and the positionsllocations of the cones. This investigation will optimize the time expended in the field investigations to collect bathymetric, side scan and core hnrings. It is belleved that the U.S. Corps of 'Bngincaers may have destroyed the original cores, that were collected in tho 1970's and the 1980's. Upon completing the four day field jet probe investigation and analyzing the sand material, ATM will finalize the boundaries for the bathymeinc survey to perform Task t.4 and Task 1.7 as described below. Task 1.4 Bathymetq Surveys of f' lential S pi rr�e Situ Bathymetric data will be acquired for the identrfied borrow areas. wrath all instrumentation integrated to an onboard vessel navigation and tracking system (HYPACK'") Vessel position will be interfaced with a Trimble"' Differential Global Positioning System (DGPS).

This field investigation will be undertaken when the borrow areae are determined from the results of the core baring investigation described in Task 1.7. if the hardbottom snapping requires site -scan sonar for specific featufes identified in the Task 2 investigations, the side -scan sonar mapping may be expanded to include these additional target area(s). Field efforts in June 1999 should help to ensure that weather patterns are favorable to sustained moderate to calm sea state conditions critical to precision data acquisition. Additionally, if evidence of sub-bottorn strata indicates rock fragments (i.e., in core borings) or underlying rock (i.e.. during jet probes),. a seismic study of the candidate borrow area will be investigated using an integrated Klein", seismic/side scan towfosh to optimize field time and data acquisition at the time of the side -scan survey (costs are included as a optional, additional cast item below in Task 1.9). Task 1.6 Process Side Scan Data Side scan data will isolate hardbottom features mapped on the seafloor and will also present a relative distinction between surface sediment types. Seismic record review and interpretatioi i will focus on acquiring areas of hardbottom that may effect dredging limits and maximization of dredging activity pursuant to project construction (e.g., locations of pipeline corridors). Areas displaying emergent hardbottom (reef) and near-bottorn submerged structure will typically require that such offshore segments be bounded or eliminated from consideration in their entirety to avoid disturbance of sensitive marine biological communities and damage to dredging equipment. Alternate plan and cross- sectlon views of the borrow areas will be developed in Task 3.1 using the vibracore data. 99tumr1A(0 ane tlaalpnVIAed WE ACOPE OF MRK 0420590, pfprf Vf+l4ff Page 4 These findings will be presented to the County prior to proceeding with side scan sonar field invesiigaiions of the identified borrow areas. Task 1.7 Obtain Vibracores in Tareet Areas The number of cores will be optimized based on distance from shore, planform 40 geometry of the candidate site(s), water depth, anticipated core lengths necessary for logging, sampling and archival, and apparent material composition. It is assumed that vibracores will bu collected during 7 field days and that 48 to 52 vibracores will be 0 recovered. It is estimated that, for the purposes of this study, a reconnaissance -tenet spacing will initially be utilized in the areas of potential sand deposition. Should the field acquisition of vibracores reveal consistently high quality (and in -field estimates of quantity) material in one or more of the candidate sites, efforts will be intensified in those areas to reduce the grid coverage area and, in effect, produce a ptans-and- sperificalions-Invel riistributlon of vibracorRs. Constnrction plans and specifications - level vibracores should be acquired on an approximately 1,000 ft grid completely covering the area of anticipated sand excavation. A conservative estimate of five to eight 20 -foot vibracores per field day is assumed over the course of the single mobilization effort. The vibracoring effort entails positioning a Coast Guard certified coring vessel over a previously determined (or Engineer -directed) coordinate set offshore. Once in position, the coring system utilizes a pneumatic impacting piston mounted on the torp of a core barrel constructed of steel or aluminum pipe and fittest with an internal plastic liner to contain the sediment core sample The core barrel is mounted on a stable platform and serves additionally as a guide to the vi"or and care barrel The conrtg system is deployed to the ocean bottom and relneved utilrzrng a deck -mounted hydraulic crane.

Grain size analysis will adhere to As I M standard 17-422 for mechanical particle size analysis of the soils. Should the samples warrant, carbonate and organic content procedures can be employed as well Analyses will be conducted by mechanical sieving utilizing a set of nested screens dividing sediments at 'J� phi intervals from -4 to +3.a ,phi, with the +3.75 phi (#200 mesh screen). Laboratory quality assurance procedures dictate that a replicate of approximately 5% of all samples taken for grain size analyses is undertaken. Grain size distribution of samples processed in accordance with the above procedures will be analyzed using the method of moments and graphic methods as described by Folk (1974). Tabular summaries of each sample will be generated and will report sieve size, phi size, mesh opening size in millimeters, weight of sediment retained in grams, cumulative percent retained, and cumulative percent passing. Sample statistics (e,g., mean, standard deviation, skewness and kurtosis) will also be displayed in the summary tables. A frequency plot of grain size distribution will be provided for each sample in accordance with USACE Form 2087. Upon completing the above described materials tests and analyses, the cores will be packaged in suitable containers and transferred to the County for permanent storage at a designated location within the County.

The above • interpretive: maps will accompany graphics of the areas investigated from the side scan grid and bathymetric surveys for candidate borrow areastsources containing suitable sands for beach placement. The side scan data will he generated as a plan view interpretive AutoCAD format rendering of the relative location of surficial sediment type, hardbottom features, and other visible features from the side scan records. For costing purposes, it is assumed that side scans and bathyrnetric surveys will reap a total area of 1,250 acres. Hardbottorn areas identified by the side scan sonar images for locations within and contiguous to tine areas surrounding the borrow areas will be investigated if these areas are anticipated to impact on the design of the borrow area. It is further assumed that magnetometer surveys, if required by FDEP, will be performed under a supplemental work order from the County during the permitting process. Sub -bottom Survey (Supplemental Work asRe-guired) If sub -bottom data records are deemed necessary and performed to confirm the depths to rock, the vibracores will provide the geophysical data necessary to map the sub -bottom strata and sand/material layers. If rock is encountered within the candidate borrow areas of the surrounding areas during the jet probe investigation, the acoustic records will utilize the core(s) c'ata for "ground -truth" verification of the material thickness. The cost of performing the seismic surveys concurrent to the side -scan surveys of the borrow areas will not exceed $10,000. This work will include preparation of contour maps of the thickness of sandy sediments and the elevation, referenced to NGVl7, of the underlying bedrock will be prepared. ATM will provide a preliminary ranking of sand source areas based on the sediment characteristics associated with each candidate borrow area. A high-resolution, three-dimensional color contour map will be produced, as will mesh plots of sand thickness and depth to bedrock. Task 2; Environmental Assessment of Nearshore Hardbottom Resources Introduction The proposed Project initiatives for BPP Planning Sectors 1, 2, 3 and 7 comprise the restoration of approximately 5.5 miles of Iridian River County Atlantic Ocean shoreline. It is along these segments of shoreline where the hardbottom resource environmental assessment (EA) will be concentrated. Verification -level work will be performed in Sector 5, (as indicated in Task 2.7), since an extensive hardbottorn mapping and characterization effort was conducted in this area in 1993. Task 2,1 Review of Published Information and Determine Field Inyestigation Boundaries As indicated in Task 1.1, previously prepared documents concerning nearshore biological resources, aerial photographs, and Prefabricated Erosion Prevention Reef Project monitoring efforts have resulted in the accumulation of information which will be reviewed prior to conducting any field work in association will'i this Project. County files will be accessed, and inquiries will be directed to the appropriate state and federal agencies (e.g„ FDEP, USACE, U.S. Fish and Wildlife Service) to determine that all available information on nearshore resources in the Project areas is properly reviewed. Task 2.2 Video Transects to Perform t- iardbottomfReef Ma in Natural resource mapping and hardbottom area characterization along the nearshore area (to approximately -18 feet NGVD) contiguous to each sand placement area and nearshore zone fronting the adjacent beaches that extend 1,OOD feet north and 3,000 feet south of Project beach nourishment areas will be performed. This work will be conducted between May 1 to June 30 or as soon as favorable weather and water clarity conditions permit. ATM shall acquire all nearshore resource information within these boundaries and pertaining to the proposed Project borrow area and fill area. YP4PMW6 W9404 V4WI $;NWF 14 l4[iNK 1WN—, lochisfCiif . pproft rj 12age B Investigation of the existing nearshore hardbottormreof will be perfonned by experienced marine biologists using underwater video taping at 82 shore -normal transects spaced at 500 feet alongshore and extending along 1,500 Feet transect lines. Additionally, three shore -parallel transects will be run the entire length of the reef structure throughout Sectors 1, 2, 3, and 7 at a spacing that is dependent upon the hardbottom locations within each sector (where the County's aerial photography will be used to determine the final line locations for the shore -parallel transects), The cross -shore and shore -parallel surveys Include coverage for areas that extend 1,000 feet north and 3,000 feet south from the north and soutir Project limits of the three identified beach nourishment Project areas. 'This coverage and work ;plan is in accordance with FIJEP staff recommendations pertaining to the hardbottom mapping and characterization work plan. Approximately 47 miles of bottom surveys will be performed to map locations of specific hardbottom structures, which will include both transect reconnaissance and continuous video 6 coverage. The four diver/marine biologists performing this work will analyze the videos to establish type of hardbottom habitats, typical species lists and relief of the reef/structural features. This scope of work and line density assumes f QPP will eliminate the necessity for side - scan sonar coverage of the nearshore zone. After the area is videotaped, a comprehensive list of fish community classifications will be provided on each hardboitom/reef that is videotaped. FDEP has stated that they may request further investigation of significant hardbottom features identified during the performance of work described in Task 2. Additional work may include supplemental quadrats, sand level/elevation monitoring and/or side -scan surveys. Investigation of each hardbottom/reef will also be completed by establishing eight permanent 1 -square -meter quadrat photographic stations on the selected hardbottom/reefs in the Project areas. Quadrats will be permanently marked by drilling and cementing two 1!/4 -inch PVC pipes into the reef. Each quadrat location will be located using DGPS. Stationary underwater photographs will be taken at each quadrat, during each monitoring event, to document the condition of each hardbottomtreef over the life of the Project. Task 2.3 Reduce DGPS Data and Develop Graphical Outouf Video transects and GPS data will be reduced for the 47 fine -miles of data collected in Task 2.2. ATM, working with CSA, will develop track lines and locations of all identified hardbottom resources. Color graphics and maps of transects, hardbottom features and quadrats will be developed to follow the video and photographic documentation. Task 2A Biological Assessment A biological inventory of hardbottom/reef communities will be conducted on all resources located within the Project's limits. Also, a description of biological/benthfc communities will be presented to identify the nature and abundance of all marine life with the study area. Classification of benthic communities will be performed by obtaining three replicate arab samples (cores, ,petit or full-size ponar grabs) from each sample station. Four stations will be selected in the 'Project areas and two stations outside the Project area to be used as controls. Each grab sample will be sieved through a #30 sieve prior to being placed in double zip -lock bags. Each sample will then be preserved in a 10% buffered formalin solution with Rose Bengal stain to aid in identification. Once samples arrive in the laboratory, they will be sorted and enumerated to the lowest possible taxon by a trained biologist. At each station, limited in sibs water quality measurements will be taken. The parameters measured will include temperature, salinity, pH, dissolved oxygen, and turbidity. Water samples will be collected near the bottom with a nanson bottle and on the surface. �Mnn ae'q tl�llr(�+.-1 �evY/SCGii SII tW INN 1WXW &, 3recCrrufcaf Appmaaff Page 7 Task 2.5 1 fi ion of h e +o l iia_ 1Following the completion of the above sections, a full evaluation of the type, sensitivity, and compatibility of the nearshore environment will be presented. The Hardbottom/Reef Mapping will be presented on video for each hardbottomfreef In the respective Project area that Is used as a video station. An inventory list of each species observed on the video will be included for each reef shown. The Biological Assessment of each 40 hardbottomi'reef will be presented with underwater photographic documentation at each quadrat, along with a species list for each sample station. Benthic communities will be statistically compared to evaluate changes in faunal abundance, and number of species present among sample sites and controls over time. Analyses will include analysis of variance (ANOVA) or non—parametric Kruskal-Wallis test, as necessary. Comparison among specific treatment groups will be completed using Student-Newman-Keuis gist (parametric and unparametric design). Diversity Indices may be computed from each area (ail samples combined) using Shannon's diversity index (H), species richness (SR), and evenness (J). Changes in overall community composition among sites and seasons can be evaluated using a proportional similarity coefficient (Bray -Curtis) with a flexible sorting strategy and a cluster intensity (13) of —4.25. Task 2.6 Evaluation of Hardbottom Areas and Potential Sediment Im acts The results of the nearshore field investigations and laboratory studies will be summarized in a report entitled "Hardbottom Mapping and Characterization for the Indian River County Beach Preservation Plan Project Sectors 1, 2, 3, 5 and 7". In addition, hardbottom characterization maps will be prepared documenting the acres, types of hardbottom areas and locations associated with each Beach Nourishment Project area. Ninety days from Notice to Proceed is the time frame anticipated to collect the field data and conduct the analysis described above. Task 2,7 Sector 5 Verification of 1993 Hardbottom Mapping and Characterization A study of the nearshore hardbottom area offshore of Sector 5 was conducted for Indian River County in 1993. Due to the extensive mapping and characterization effort expended during this study, FDEP is requiring that the County conduct a verification -level field investigation and characterization of the nearshore hardbottom resources within the Sector 5 study limits. FDEP Bureau of Beaches and Coastal Systems requires that verification of the 1993 study be conducted by replicating 8 of the 32 shore -perpendicular transects and four of the 13 photoquadrats. As it was determined that a relatively uniform spatial distribution of transects be replicated throughout the fill project limits, staff at the Bureau of Beaches and Coastal Systems were consulted to determine the location of the transects. The location of the eight transects are as follows: R-73, R-74,5, R-761 R-77.5, R-79.5, R-81.5, R-84, and R-88.5. Transects will be run over a distance of 2,044 ft. from the shoreline in a seaward dirction or vice -versa (i.e. in one direction only as the previous study ran each transect line essentially twice). In addition, a share -parallel transect will be conducted which will follow the nearshore edge of the reef feature over the entire length of the Sector 5 shoreline. Underwater video taping will be performed by experienced marine biologists along each of the transect lines. The four photoquadrat stations to be re-established are: IN -N-1, V1313-19-774, CMS -19- 1197, and IN -S-1'. These stations were selected (based on concurrence with Mr. Lutz of the FDEP Bureau of Beaches and Coastal Systems) to represent two stations with a high percentage of worm rock, and the other two stations representing a high degree of NO - diversity. An attempt will be made to field -locate these existing stations (assumed to be PVC pipes or similar permanent fixtures in rock outcroppings) utilizing on -board DGPS, with stationary underwater photographs taken at each station. to Q+v"aa.0 SCaw 00 WWX 041,Wrt, MW TixellrnlhW AAWD"b Page a Upon completion of the field work, the video transects and DGPS data will be reduced for the 9 8 line -miles of data. Color graphics and rnaps of tho transects, hardbottom features and quadrats will be developed. The work components of Tasks 2.4 and 2.5 (less in situ water quality measurements) will be repeated for this project segment. Preliminary evaluation of potential hardbottom impacts will be performed for Sector 5, with hardbottom characterization maps produced. Overlay plan and cross-section views comparing the 1999 versus 1993 data will be produced and a report prepared by CSA and ATM for submission to the FDEP. Subsequently the FDEP will review and interpret the report and verification data to determine if the 'updating' of the Sector 5 mapping and characterization effort validates the 1993 hardbottom mapping. Task 3.0: Project Pro -Engineering, Design and Feasibility Report Introduction The Beach Nourishment Projoct Pians, Design and Environmental Assessment Report will utilize the data and information developed for the geotechnical and hardbottom mapping studies (Tastes 1 and 2) to: identify, evaluate and rank the candidate sand sources; determine locations of significant hardbottom areas and potential impacts of sand nourishment an the nearshore hardbottom resources; Identify the primary technical, environmental and logistical factors effecting Project design; and develop revised Project cost estimates based on the recommended Project design, This information will provide the basis for analyzing and evaluating alternative Project design features for each Project area including the attendant cost estimates with development of a Beach Restoration Design Memorandum Report to accompany the County's. Project permit applications) to the State and Federal governments. Given the County's Project schedule for construction of the Sector 1, 2, 3 (and potentially Sectors 5 and 7) in FY 2000-2001, it is anticipated that permit applications would be filed in July or August 1999 to acquire construction permits on or about July 2000 and, subsequently, to procure competitive bids for construction work to begin November 2000. Task 3.1 [lesion Alternate Geometric Configurations for Borrow Areas and Develop Composites for Varying Excavation limits The sand source investigationlgeotechnical studies will provide the data for the development of alternative geometric configurations of excavation within each identified borrow area. It is anticipated that 3 to a borrow areas will be identified and evaluated for the sand placement areas in Sectors 1, 2, 3, 5 and 7. This task will perform analyses of alternative cut depths and pian view configurations to determine the design which maximizes the performance of the beach nourishment Project (i.e., longevity of the beachfill), provides the desired nearshorelequiiibrated profiles slopes, and provides suitable quality nesting habitat for the endangered sea turtle. An evaluation of the composite sand characteristics for each candidate borrow area "alternate cut configuration" is critical to developing an optimal design in terms of Project performance and reducing the impacts on nearshore hardbottom habitat. This analysis will also evaluate the cut configurations in terms of reducing excavation and sand conveyance costs to each Project area. Adjustment slopes for differing sand quality will be developed to evaluate the sand characteristics that will meet FDEP requirements for sea turtle nesting and provide minimize encroachment on the hardbottom. Task 3.1 will provide section view and plan view drawings in state plane coordinates with dredge volumes, excavation depths, and sand composites for each borrow area. Task 3.2 Pry ect Pians and Design Conceptual level design principles will be employed to determine alternative beachfill template configurations and requisite sand volumes needed to construct the feeder beaches and beach nourishment Projects planned in Sectors 1, 2, 3, 5 and 7 of the BPP_ Alternative unit quantities of sand will be evaluated based on the material characteristics determined for each candidata borrow area and the proximity to significant hardbottom features. A comparison of "native" versus borrow arr.a(s) grain size characteristics will be analyzed to assess the stability and longevity for the recommended sand source. Plan fe rhnICA) APprOSCIt Page 9 view (1' = 200 feet) and section view (.at 1000 foot spacing) drawings will be prepared for two alternate configurations at each of the five Project areas (Sector 1, 2, 3, 5 and 7). The cross-section drawings will indicate design templates, advance fill templates, adjusted post -nourishment equilibrium profile, equilibrium We of fill, locations of hardbottom and the borrow area location relative to the Project. Task 3.3 Develop Project Cost Estimates Probable costs of engineering design, permitting, construction, and past -Project performance monitoring will be tabulated and presented in the report. Mitigation of nearshore hardbottom resource impacts will be estimated and probable costs for this item will be presented, Potential issues that could result in delays in permit acquisition will be identified. A suggested timeline for completion of significant design, permitting, bidding and construction milestones will be included in the report. Construction costs will be estimated to including mobi lizationldemobil ization, unit costs of sand excavation, delivery distances, and placement quantities, and mitigation and phys callbiological monitoring, An evaluation of alternate construction sequencing of Projects will be performed to evaluate the potential to reduce overall Project costs. All such costs shall be based on the information attendant with the expected sand source locations, hardbottom mapping studies and resultant artificial reef acreage's required for Project mitigation and the FDEP's standard Project monitoring requirements. Cost estimates will be developed in June 1999 for purposes of County planning purposes and formulation of the County's financing plan to implement the BPP (cost estimate #1). It is anticipated that three revisions of the project cost estimate will be required. Study findings and Project design recommendations will be presented to staff, the public through workshops, the Beach Advisory Committee and the County Commission, Task 3.4 Beach restoration Destgn Memorandum Report The Beach Restoration Design Memorandum Report will provide the information needed to file and initiate the processing of the Project permits including developing design beachfill templates, environmental resource mapping and sand characterization in sufficient detail to support applications to the 'State and Federal agencies. This report will detail the following: * sand source investigation/geotechnical data and overlay mapping of features, analyses of composite sand characteristics for alternate borrow area configurations for each candidate sand source with borrow areas mapped, ♦ natural resource mapping, hardbottom area characterization and quadrats along the nearshore area (to a depth of -18 feet) contiguous to each sand placement area and nearshore zone fronting the adjacent beaches that extend 1,000 feet north and 3,000 feet south of Project beach nourishment areas, typical beach nourishment section view templates, unit fill quantities (cylft), design beachfill quantities for each Project area and identified sand source including overfill quantity estimates (if required) and development of cost estimates based on the recommended sand sources, t side scan maps and bathymetric maps for the identified candidate borrow areas, graphics and exhibits for the permit pre -application meeting with the county, state and federal agencies to submit the report for their review. Plan and cross section views of beachfill template overlays on existing beach profile data (with the results of the environmental resource mapping depicted as an AutoCADf+GIS layer -controlled feature) will show the proximity of fill to existing natural resources. If the character (relief, biodiversity and location relative to shore) of nearshore hardbottom resources indicates a perceived immediate (direct burial by beachfill) or secondary (longshore and cross -store redistribution of sand subsequent to fill placement) impact to the resource, the total sand coverage acreage (both vertical Qr� "V. d -W vP Vw"A Vi KC *,1 tit Na Mae Usti X"" %eci*lonit WAApmaca Page 10 and horizontal) will be developed and the expected mitigation requirements for this anticipated impact will be evaluated to determine if changes in the design will eliminate or reduce the impact. The total area of potentiallexpected sedimentation impact will be determined by Sector, the costs of mitigation quantified, and the approximate costs to construct this mitigation area(s) will be included in the revised Project cast estimates.. r The survey of nearshore hardbottom resources will provide the information needed to furnish the FDEP with information to document potential impacts on these resources. The extent (aria coverage) and approximate relief of exposed rock outcrops shall be • determined by a combination of digitizing County -furnished color positive aerial photographs and diver transects over the hardbottom structure to determine reef character and vertical relief. Diver transects witl provide mapping and representative photographs of relief and character. Video mapping will verify vertical relief and provide representative images of the exposed rock features for analysis and color overlay mapping of hardbottom features for presentation in the report. Subsequent to determining the locations and character of the hardbottom resources located along the Project beachfill areas, ATM shall produce a plan view depiction of the April -May 1999 shoreline, adjusted equilibrium toe of fill and the field -verified hardbottom mapping. The latest aerial mapping effort performed by County staff will be imported into the drawings of the plan view characteristics of the beach nourishment Projects with the resource information for comparison. This map will be utilized to determine potential impacts associated with the beachfill template to the nearshore hardbottom areas. Alternative beachfill templates will be overlaid as a layer. The beach nourishment templates will be imported as the final layer to determine total acreage(s) of impact to viable nearshore hardbottom communities, Such impact acreages will be computed from this overlay information and presented to County staff for consideration. Task 4: County -Wide Beach and Offshore Profiles 4.1 BEACH AND OFFSHORE PROFILE SURVEYS Reach and offshore profile surveys will be conducted to acquire updated information in those areas of the County not currently subjected to monitoring by the Sebastian Inlet Taxing District and the PEP Reef Monitoring. Beach and hydrographic surveys will be performed from the dry upland beach (typically beginning at the FDEP Reference Monument) to an average distance of approximately 31000 ft offshore or to the —30 ft NOVD contour (whichever results in the greater profile line length). In addition to the anticipated physical limits of beachfill placement north -south within each Beach Sector, surveys in each Sector will extend 1,001) feet north and 3,000 feet south. These data will be necessary to guide the permitting and design documents to be prepared for each of the identified Beach Sectors requiring beachfill placement. To provide coverage, the following stations will be surveyed in April -May 1999. In addition, stations that are routinely surveyed by the FDEP using hydrographic survey techniques (i.e., long -line surveys) are also identified below. These data will supplement the County's long-term beach monitoring program. The beach profile lines to be surveyed are as follows: R-33 R-66 R-106 T-36through R-51, inclusive R-69 R-108 R-54 T-72 1k-109 R-57 R-75 R-110 R-60 R-93 R-111 R-63 R-99 through R-104, inclusive T-117 Further, available data has been analyzed to identify those FDEP Reference Monuments which should have bathymetric lines run further offshore to delineate portions of the Indian River Shoal. This information will be utilized to locate the jet probes for the geotechnical investigation phase of the work.

This meeting is proposed to take place concurrent with the Joint Coastal Permit pre -application meeting (described in Task 3.1) to optimize travel expenditures to Tallahassee. 6.2 Mixinq Zone Variance Raguest and Completeness Summary Response A Petition for Variance request will be prepared by ATM, with an anticipated north limit of the mixing zone and an adequate distance cross -shore and alongshore on the Atlantic Ocean coast to avoid water quality violations. The quality of the borrow source sand to be utilized for the nourishment Project will be better determined pending review of the borrow, source material composition with the County and will likely dictate the physical dimensions of the mixing zone which is achievable and hence requested. It is anticipated at this time that the transverse -misting model presented in Fischer et al. ("Mixing in Inland and Coastal Waters," Academic Press, Inc., 1975) will be utilized to perforin the analysis required for the Petition for Variance. Should the borrow area material composition or the regulatory agencies dictate an alternative evaluation, ATM fees for this service may require modification. Forty-five days from authorization to proceed from the County shall be sufficient to prepare the request. ATM shall respond to one agency Request for Additional Information associated with the mixing zone issue to ensure that the appropriate mixing zone is acquired. It is anticipated that the variance can be obtained in the same timeframe as the Joint Coastal Permit, and will likely be deemed complete pending completion of a singular completeness summary response. All attempts will be made by ATM to respond to the agency request within 60 calendar days of receipt of the RAI. County shall prepare a Public Notice following agency approval of the Petition for Variance methodology and computational results. ATM shall review the FDEP variance document for accuracy and shall transmit any noted changes required to the County prior to subsequent transmittal to the FDEP requesting such change(s).
