Indian River County Work Order Number 2018007-3 Sector 7 Beach and Dune Restoration Project Exhibit 1 - Scope of Work Exhibit 1 Scope of Work 2019 Reconnaissance Hardbottom Survey Introduction: The "Indian River County Beach Preservation Plan Update" (Plan, dated February 2015) recommends re -nourishment of beaches within Sector 7, which extends from Florida Department of Environmental Protection (FDEP) reference monuments R-97 to R-108 (Project). The Projectextends approximately 2.2 miles; a majority of the Projectarea is designated by FDEP as critically eroded. Sector 7 was damaged by Hurricane Matthew in 2016 and Hurricane Irma in 2017; beach re -nourishment is warranted. Construction and re -nourishment of the Project area is anticipated between November 2020 and May 2021 - outside the sea turtle nesting season. The COUNTY previously authorized Work Order Number 2018007-1 for design and permitting of the Project. In concert with permit applications, FDEP has (a) identified the existence of recently exposed nearshore hardbottom, and (b) required a reconnaissance survey to map and characterize existing nearshore hardbottom that is susceptible to adverse impacts from the proposed Sector 7 re -nourishment. The objective of the survey is to document the current types, and spatial distribution of hardbottom resources just offshore of the beach nourishment Project area, and in the vicinity of the potential pipeline corridor. The survey is expected to (a) be conducted between August and September 2019, and (b) frame future monitoring activities. The survey work will be performed by CSA Ocean Sciences Inc. (CSA) and Morgan & Eklund, Inc. (M&E) under sub -contract with Coastal Technology Corporation (Coastal Tech), who will oversee and incorporate results into the preliminary design permit sketches for modification of permit applications. The following describes the specific scope of work under this Work Order. Task 1.1 Side -scan Survey: A side -scan survey will be performed by Morgan & Eklund, Inc. to verify the locations of hardbottom within the Project area seaward of the 2007 permitted Equilibrated Toe of Fill (ETOF). The side -scan survey will be performed between FDEP R - monuments R-97 and R-111 and offshore a distance of approximately 350 m. The survey will also be conducted within 25m of the potential pipeline corridor. Hardbottom mapping data collected during the side -scan survey will be recorded and provided digitally. Coastal Tech will compare the side -scan survey to the 2019 beach profile data provided by the County and the preliminary habitat map and incorporate this information into the permit sketches. Task 1.2 Preliminary Habitat Map: Via desktop, CSA will characterize the Projectarea utilizing information available on the condition and distribution of hardbottom resources. This information may include historical and current sonar surveys and diver delineated hardbottom edges, previous biological monitoring data and other applicable information for the Project Area. The work will include the existing hardbottom distribution (nearshore, intermediate, offshore) within the Project area and under the influence of the Project (300 m updrift, 900 m downdrift, and 30 m seaward of the current beach and seaward of the 2007 permitted ETOF) will be determined. In addition, the survey area for the proposed pipeline corridor shall encompass all areas within the corridor as well as areas 25 m on either side of the corridor. Page 1 of 2 July 31, 2019
