SCOPE OF WORK Indian River County Beach Preservation Project — Sector 7 Monitoring and Tilling Services Introduction: The Indian River County Sector 7 Beach Renourishment project is located along the South County shoreline and extends between FDEP reference monuments R-97 and R- 108 . The proposed beach nourishment design includes the placement of a total beachfill volume of approximately 363,600 cy, which includes the placement of 36,400 cy of sand for the dune enhancement feature. Construction of this project is anticipated in the winter of 2005/2006 (concurrent with the Sectors 1 & 2 project) . This scope delineates monitoring and tilling services required under State and Federal permit. Task 1 - Nearshore Hardbottom Monitoring Plan Monitoring of nearshore hardbottom is required under both State and Federal permits for the project. Field work required as part of this monitoring has been approved under separate task order (Task order #13) and will be performed by Continental Shelf & Associates under subcontract to ATM. This scope authorizes additional QA/QC oversight of the monitoring by an independent entity (Coastal Eco-Group) as requested by FDEP staff. This task also includes additional coordination with FDEP staff regarding monitoring status, level of observed impacts and the monitoring plan . This additional effort will allow for proactive responses to agency concerns regarding the project and specifically impacts to nearshore hardbottom resources. Task 2 - Nearshore Turtle Monitoring ( Fall 2006 to Spring 2009 ) The Biological Monitoring Plan for the Indian River County Sector 7 beach restoration project contains an element for assessing sea turtle population levels in the nearshore area throughout the County. This assessment is to be conducted semi-annually pre- construction 2006, and continuing for three successive years thereafter. In-Water Research Group (IRG) will complete the field and statistical efforts described in this task under subcontract with ATM. The data is to be used to determine seasonal differences in sea turtle abundance in the nearshore environment, as well as differences in sea turtle abundance at differing distances offshore and at different locations within the County. To provide for sufficient data for analysis, two complete surveys, as described below, will be needed each sampling period. The complete project will require seven sampling periods, with two sampling events per period , for a total of 14 countywide sea turtle surveys. Task 2. 1 Field Surveys: Surveys will be conducted along a series of 3-kilometer long transects previously established by Indian River County. Study sites and survey methodology will be in accordance with the Indian River County Sector 7 Beach Restoration Project Biological C'.9)=M" and SeUwVp onWWVWo l SelliegsUempolery ke et Ftla %OLQEW ea 1
