Indian River County Sector 3 - Beach Restoration Project Additional Services Scope of Work bottom along a baseline projected directly east from each of the listed monuments . The nearshore edge of hard bottom along each of these baselines shall be determined and each transect shall then be extended 180-m east of these positions . The transects shall be permanently established using 50-cm long steel rods to mark each 0 point at the landward edge of exposed nearshore hardbottom . If a ledge exists at the nearshore hardbottom edge, the 0 point shall be located oil the top (l.e. crest) of the nearshore hardbottom ledge on the horizontal surface. Rods will then be installed along all transects at the 5-meter mark, 10-meter mark, and 20-meter mark . At every 10 meters from 30 meters until 100 meters, and then every 20 meters until 180 meters a 20-cm long stainless steel eyebolt will be cemented into the bottom. At 180 meters a 50-cm long steel rod will mark the offshore end of the transect. Each rod or eyebolt marking a 0-mark, 10-meter mark, and 20-meter mark shall be identified with a tag marking the position along the 180-meter transect. The rods shall extend a minimum of 30 cm above the hardbottom surface and the eyebolts shall extend a minimum of 10 cm above the hard bottom surface. No rods shall be located within the sand gaps between hardbottom ridges. If significant sand gaps (i.e. troughs) occur between the hardbottom ridges , a steel rod shall be placed at the seaward edge of the first hardbottom ridge, and installation of rods/eyebolts will recommence at the next hardbottom ridge with a rod at the 0 mark (crest or edge of exposed hardbottom) . Eyebolt installation will then continue at 5 meters from the second 0 mark, and then every 10 meters until the 100 meter mark, then continue every 20 meters until 180 meters . DGPS positioning will be obtained for the landward edge (0 mark) and seaward edge of the first nearshore hardbottom ridge, and or all subsequent hardbottom ridges/exposed hardbottom located seaward along the 180- meter transect. DGPS positioning also will be obtained for the 180-m point along each transect. The 180-meter transects shall be sampled using digital video in progressive scan mode. The diver shall swim at a speed of approximately 20 meters/6 minutes (-3 .5 meters/minute) with a constant camera distance of 25 cm above bottom during the portions of the transect to be quantitatively analyzed. For the remainder of the 180-meter transect, the diver shall swim at a speed of 20 meters/5 minutes (-4-5 meters/minute) with a constant camera distance of 25 cm. If the diver is moved off the transect by surge, the diver shall return to the point where he/she was disturbed by the wave action, and resume filming at that point. The video transects shall be reviewed during the course of the survey to ensure that there are no gaps in the data due to diver error and that the quality of the video is acceptable for video analysis . Any missing video transect data or poor quality video shall be re-filmed during the course of the event. Landscape panoramic views shall be recorded with the digital video camera at the start and end of each transect, and at each interruption of the transect by a sand gap/recommencement at the next hardbottom ridge or hardbottom exposure. Additionally, close-up video of the tag marking the pin at these locations shall be filmed for a frame of reference for the observer viewing the video record. Close-up digital still video and/or photographs shall be obtained of representative benthos along the transect to aid in identification during video analysis. Still photographs shall be obtained using the digital video camera or digital still camera at all quadrat locations (Task 2c) , vertical ledges , large Oculina spp . colonies or Siderastrea siderea colonies along the transect or Page 5 of 14 June 13, 2007
