Indian River Countv Sector 3 - Beach Restoration Project <br /> Additional Services Scope of Work <br /> each monitoring event. This also ensures that each person examining a particular image <br /> will view the same points, thereby allowing for double-blind counting for quality <br /> assurance and control purposes . Ten percent ( 10%) of the images shall be counted by <br /> two scorers to assess inter-observer variability. <br /> An estimate of percent cover (projected to the surface) will be performed for each image <br /> according to the following functional groups/categories : scleractinian corals (to the genus <br /> level), octocorals, macroalgae (to the genus level if possible, if not, then according to the <br /> following breakdown : calcareous red, calcareous green, fleshy brown, fleshy red, fleshy <br /> green), microalgae/cyanobacteria, sponges, tunicates, hydroids, wormrock, zoanthids , <br /> urchins, holothuroids, and substrate . Substrate shall be broken down into the following <br /> categories : unconsolidated substrate (rubble/shell hash, rhodoliths), sediment over <br /> hardbottom, sediment over benthos (where the underlying fauna cannot be identified due <br /> to the sediment cover), and sand. <br /> The remainder of the 180-meter video transect shall be reviewed for qualitative changes <br /> in benthic community cover/composition in comparison to the pre-construction surveys, <br /> previous annual surveys, and the reference sites . If the qualitative review of the video <br /> transect suggests sedimentation impacts or cross- shore transport of sediments over the <br /> benthic community along the remaining portions of the transect, and the results of the <br /> sedimentation monitoring and quadrat assessments indicate burial of hardbottom <br /> communities, additional quantitative analysis of the video transects shall be required as <br /> directed by the Department to determine the extent of the project-related impacts. <br /> In addition, CSA INTERNATIONAL will provide biological data and DGPS <br /> coordinates to DCA to assist them with definition of the classification types for the <br /> hardbottom maps (prepared by DCA under Task lc) . <br /> Task 2e - Summary Report: CSA INTERNATIONAL shall prepare a Summary <br /> Report of Task 2 results in both hard copy and digital format. The report shall include <br /> appropriate graphics/tables, statistical analysis of the collected data, with the following <br /> data on CD: <br /> a) all digital video transects and frame-grabbed images from all transects <br /> b) Point Count files and associated data (i.e. PTS files, MGR files, cd.dat files ) <br /> c) Excel spreadsheets of Point Count data (raw data and summary files), and <br /> d) Excel spreadsheets of in-situ quadrat data. <br /> e) Spatial GIS shapefiles of transects and hardbottom maps . <br /> Task 3 : Turtle Abundance <br /> Task 3a — Field Survey: In general, IRG will perform a field survey to assess marine <br /> turtle abundance in the Study Area. The surveys will : <br /> a) be performed in the summer of 2007 <br /> b) entail three 3 -km long transects at 3 different distances offshore in the Project <br /> Area <br /> Page 9 of 14 <br /> June 13, 2007 <br />
