0 Prepare Pre -Engineering Design/Feasibility Report <br />A general description of the scope of consulting services is as follows; <br />A. nt -Wide f h t' Sand Seareh Inver i ation <br />Geological Investigation: This phase of the study will be used to investigate and <br />analyze any previous work which may exist in the project areas. Any historical reports <br />and/or existing data which will provide useful information in identifying potential <br />borrow areas far the investigation. <br />• Aerial photography will also be used (provided by the County) of the projtict areas to <br />identify geological characteristics and pinpoint regions of possible sediment. <br />Jet Probe Investigation; A jet probe survey will be used to help guide the selection <br />of ;potential coring sites and to provide the basis of estimating the volume of borrow <br />sands. <br />Sand Source identification. Following the seismic survey potential borrow areas will <br />be selected for core sampling. <br />Core 5amplirig & 5edimentology: Core samples (via vibracores) will be taken in all <br />potential borrow areas. Labr,ratory testing will be iaerformed to identify the sediment <br />classification (ASTM). Ibis classification will allow (he* compatibility of the recovered <br />sediments to be determiners relative to the native material. The compatibility of the <br />sediments will provide the basis liar determining the amount of borrow material (sand) <br />which exists in the study are.). <br />Ocean Mapping: A continuous sub• rottorn seismic reflection survey will be complelfxi <br />to record the bathymelry and stratigraphy of the proposcKl Ixrrr€rw areas.. <br />Geotechnical ReporfinglRecornmendations: At this time a report will be generated <br />which will include quality and volume of recoverable harrow area material (sand) to <br />be used to implement the four IWl projects outlined in the. React? Preservation Plan. <br />Recommendations will also be presented to identify primary and secondary borrow <br />sources for beach nourishment. Ail information and documentation presenter) shall be <br />compatible with FDFP GIS specifications for geotechnical data. <br />B. nyir rt ntal sessrnenr <br />In general, the Consultant(s) will perforin all necessary field investigations & analysis <br />necessary to complete an environmental assessment of the project limits. More <br />specifically, the work will include the following. <br />Hardbottom/Reef Mapping. Investigations to map the hardbottorn/reef will be <br />performed using techniques including, but no limited, to viclr=o data along transects <br />perpendicular to the coastline, biological assessments, aerial photography(provided by <br />the County), bathymetric survey data, etc. <br />Biological ,Assessment: A biological inventory of the hardbotiom/reef will be <br />conducted. A description of all biological/benthic communities shall be presented to <br />identify the nature and abundance of wildlife within the study area. <br />Classification of Nearshore Habitat: Following titre completion of the above <br />described work a full evaluation of the character, type and sensitivity of the nearshore <br />biological resources will be presented. <br />C. Pre Engineering QesiQn <br />Feasibility Report: A report will be generated that will outline the overall project <br />recommendation(s) with regards to the availability of sand and environmental <br />2 <br />
