Indian River County Sector 3 - Beach Restoration Project Additional Services Scope of Work c) sample along these transects 4 times during the summer of 2007 , d) follow the same methods and protocols used by IRG at 3 other sites in the county, so that the data for Sector 3 are directly comparable to those areas. This monitoring effort employs vessel-based observers to generate abundance estimates . Aerial visual surveys have often been used to obtain, information on the abundance and distribution of turtles over relatively large areas and are appropriate for documenting seasonal variations in population levels. On the relatively limited geographic scale of Indian River County Sector 3 , it is felt that an analogous vessel based approach is more appropriate. This monitoring effort employs observers who count surfacing turtles from a small boat. A semi-quantitative index, sightings per vessel/km, is calculated for each species and compared between seasons, distances offshore, and areas. The monitoring is conducted from a small boat equipped with a spotting tower capable of supporting two observers at an eye level of approximately 12 feet above the water. The GPS waypoints at the north and south ends of each transect line establish a base course that the helmsman follows. A constant vessel speed of 5 to 6 knots is maintained during all transects , verified by GPS track log. With one observer looking to port and one observer looking to starboard, the vessel proceeds along the transect line. When a turtle is spotted, it is identified to species and the position of the vessel at time of sighting recorded in the GPS unit. The position of the turtle relative to the transect line (Inshore, offshore, or on the transect line) is also recorded. A Turtle Field Survey Report will be completed by IRG summarizing the results of the monitoring effort. Task 4 : QA/QC Coordination of Investigations Task 4a — Coordination of Field Investigations and Professional Services : On behalf of Indian River County, CEG will provide general QA/QC of Task 2 and Task 3 services. Specifically, CEG will: • perform QA-QC review of video transect data using PointCount 99 ( 10% sub- sample) for inter-observer variability • prepare a QA/QC letter report to regulatory agencies citing QA/QC results . • review pre-construction monitoring report and data prior to submittal to regulatory agencies. Task 4b - FDEP Coordination: CEG will confer with FDEP staff relative to the scheduling of field investigations associated with Tasks 2 and 3 , and provide for coordination of any participation by FDEP staff. CEG will also travel and attend up to two meetings in Tallahassee with FDEP staff to review investigation results . Page 10 of 14 June 13, 2001
