Indian River County Sector 3 Beach and Dune Restoration Project Page 4 Exhibit A — 2013 Scope of Work Surveys will only be conducted when weather conditions are acceptable for survey accuracy and safety. To eliminate the effect of day-to-day variability in turtle sighting conditions on the data set, surveys of the Treatment and Control sites will be conducted on the same day. If deteriorating weather conditions do not allow for a complete survey of both sites to be conducted in the same day, the entire survey effort will be repeated on the next acceptable date at no additional costs to the County. 8) Nearshore Hardbottom Monitoring (FDEP Special Conditions No. 48 through 54). CSA will perform nearshore hardbottom monitoring within and surrounding the Project Area, extending from R-20 through R-65 (including reference areas), to fulfill requirements for "Nearshore Hardbottom Monitoring" as identified in the FDEP-approved Biological Monitoring Plan. This task will consist of two elements, field surveys along pre-established transects and ground truthing and interpretation of aerial imagery. Transect monitoring will include the survey of a total of 23 previously established permanent cross-shore transects (R-21 , R-22 , R-24, R-25 , R-26, R-28 . 5 , R-30 . 5 , R-32 , R-349 R-369 R-385 R40 , R429 R441 R-489 R-509 R-52 , R-549 R-569 R-60 . 59 Ref. R-63 , and Ref. R-65 ), with the collection of video, still photographs, and repetitive in situ quadrat data. The field surveys will also include the mapping of the nearshore edge of hardbottom along the length of the Project Area from R-20 through R-57 (approximately 36,000 ft). Nearshore transect surveys and nearshore hardbottom edge mapping are projected to be performed at a rate of 1 . 5 fixed transects surveyed per day or about 6,000 feet of hardbottom edge mapped per day, including limited time potentially lost due to local inclement weather events (thunderstorms and rough seas) which may occur during the summer survey period. CSA will digitize current aerial images obtained from the County to produce GIS = based nearshore habitat maps (ESRI shape files) . It is the responsibility of the County to coordinate with the appropriate contractor to ensure that quality aerial imagery is provided To the extent practical, the collection of aerial imagery will be timed to correspond with a period of good water clarity and allow for concurrent in situ diver ground4ruthing for habitat verification. CSA will perform ground-truth verification of the aerial photography via bounce dives and/or cross-shore video transects . Geo-referenced field positions will be included in copies of the ground-truthing photography and/or transect video record provided to EAI, the County, and FDEP . CSA will use the groundtruthing to verify interpretation of the aerials used to produce the GIS-based habitat map . 9) Post-Construction UMAM Analysis of Hardbottom Impacts. CSA will assess post-construction hardbottom impacts (physical burial) associated with the Sector
