Indian River County Work Order Number 2018007-2 Sector 7 Beach and Dune Restoration Project Exhibit 1 - Scope of Work Task lc — Update Construction Quantities & Permit Sketches: CONSULTANT will (a) analyze pre -construction surveys to be collected by the COUNTY in February 2019, (b) assess the estimated volume required for construction, update the Permit Sketches and (c) update the probable cost of construction. Task ld — Hardbottom Monitoring - Baseline Survey: CONSULTANT will sub -contract with CSA to provide the pre -construction "baseline" biological monitoring of the nearshore hardbottom generally consistent with the biological monitoring plan approved for the initial nourishment of the Sector 7 project, as the minimum amount of biological hardbottom monitoring expected to be required by the FDEP and USACE permits. FDEP and USACE Permits and biological monitoring plans corresponding to more recent projects have included additional transects and other biological monitoring requirements. The FDEP or USACE could require additional monitoring which may be authorized under Task le below. Nearshore Hardbottom Monitoring Hardbottom Edge Mapping: CSA will map the position of the nearshore edge of the hardbottom from FDEP monuments R-98 to R-110 using divers with GPS buoy for comparison with the extent of hardbottom delineated from the photography. Biological Transect Monitoring: CSA will monitor twelve (12) cross -shore permanent hardbottom transects beginning at the 2008 nearshore hardbottom edge and located directly offshore of FDEP Monuments R-99, R-99.6, R-100.4, R-101.7, R-102.9, R-103.5, R-104.1, R- 105.8, R-107.3, R-109.2, R-113, and R-115. All twelve (12) of the transects are biological monitoring transects to be performed up to 50 meters in length. A marine biologist will collect qualitative video documentation of the seafloor and associated biota along each of the 12 transect lines. Sand depth measurements will be collected at 1 meter intervals along all 12 transects using a marked steel ruler; physical transitions between sand and hardbottom will be recorded as line intercepts. Aerial Interpretation of Hardbottom Extent: The COUNTY will provide geo-referenced aerial photography consistent with the Environmental Aerial Photography Monitoring Standards identified in the FDEP document titled "Monitoring Standards for Beach Erosion Control Projects" dated May 2014 edited October 2014; the photography will extend from the vegetation line to a minimum of about 3,000 feet seaward of the shoreline. CSA will employ this photography to delineate the extent of nearshore hardbottom within the Project area. The delineation will be performed using GIS software and verified in the field by CSA divers who will perform representative bounce dives within the Project area. Page 2 of 3 January 11, 2019
