Task 6 - Juvenile Green Turtle Netting Studies Per the February 2003 amendment to the Indian River County Sectors 1 &2 Beach Restoration Project Biological Monitoring Plan , netting studies shall be utilized to directly assess the potential effects of beach restoration activities on turtles in nearshore reef foraging habitats . Data that has been collected by turtle researchers at the University of Central Florida (UCF) shall be utilized for this purpose . UCF researchers have been conducting netting for over a decade in the nearshore directly offshore from the proposed Sector 1 and 2 project area . The extensive Catch Per Unit Effort (CPUE ) data they have collected since 1989 can serve as a baseline from which project effects can be assessed . The UCF effort, despite the valuable data collected , has never had dedicated funding . Indian River County proposes to fully fund the nearshore reef netting effort in the summer following construction (summer 2003) and in two subsequent summers and to provide funding for data analysis and report preparation on the effects of the project on foraging marine turtle CPUE . Task 7 - Physical Monitoring TASK 7. 1 : BEACH AND OFFSHORE PROFILE SURVEYS In order to evaluate the performance of the beach nourishment project and identify the erosion and accretion patterns along the project and adjacent shorelines , beach profile surveys will be conducted pre and post-construction and annually in July, August, or September for three (3) years post construction and at years 5 and 7 post-construction . Beach profile surveys will also be conducted within 90 days after major storm events as determined by the DEP . It is noted that the monitoring associated with this work authorization only covers through year 3 post-construction . Beach and offshore profile surveys will extend from each of Indian River County DEP monuments R-1 through R-22 , inclusive . All beach profiles will extend a minimum of 150 feet landward of the monument or to the edge of a building or road , whichever is encountered first. Beach profiles will extend offshore from DEP monuments to wading depth (approximately —4 feet NGVD) . The hydrographic profile lines will extend 2, 000 feet seaward of the profile origin , or to the —30400t contour, whichever is further offshore; sufficient overlap will occur between the seaward terminus of the beach profiles and the landward origination of the hydrographic profiles . Profile alignment will be conducted on N 700 E azimuths , at all profiles in order to replicate the azimuths previously established by DEP for each monument. Elevations of the beach profiles will be obtained at 10-foot intervals and at all noticeable breaks in grade (greater than 1 foot vertically) . Soundings from offshore portions of beach profiles will be obtained at 25-foot intervals. Vertical and horizontal control will be referenced to NGVD 1929 and Florida East State Plane Coordinate System (NAD 27) respectively. Survey data will be reduced and furnished in XYZ format and DEP format.
