De �'fR COU��:•• 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 Indian River County Work Order Number 2018007-3 Sector 7 Beach and Dune Restoration Project Exhibit 1 - Scope of Work 1.3 Reconnaissance Diver Survey: CSA will monitor and note field conditions in the Project area daily following a notice to proceed until fieldwork is completed. Field conditions of note will include wind direction and speed, wave height, wave period, and water clarity (underwater visibility), as applicable, along with any significant weather conditions. Wave heights greater than 0.6 m typically result in increased turbidity and reduced underwater visibility, which prevents surveys from being conducted. During appropriate field conditions, CSA will perform the following: (a) Hardbottom Edge: CSA divers will use the diver positioning system to delineate portions of the nearshore hardbottom edge within the Project area and seaward of the 2007 permitted ETOF, and also within areas 300 m updrift and 900 m downdrift of the Project area, from FDEP Monuments R-97 to R-111. As the hardbottom edge is mapped, its relief characteristics will be recorded as: low (>0.3 m), medium (0.3 m to 1 m), or high (>1 m) relief. Results from this mapping will be compared to the most recent geo-rectified aerial imagery and side -scan sonar survey and will be used to verify the distance from both the shore and the 2007 permitted ETOF seaward to the hardbottom edge. (b) Pipeline corridor: CSA divers will use the diver positioning system and bounce dives to verify the distribution of potential hardbottom within the proposed pipeline corridor. Any hardbottom observed within the pipeline corridor will be delineated. (c) CSA divers will gather observations and measurements about the hardbottom relief, substratum type, sediment cover, and biological community composition and distribution within the Project area. CSA will use temporary transects to survey the Project area. Temporary transects will be approximately 30m in length. An estimated 30 cross -shore temporary transects, beginning at the landward edge of hardbottom located seaward of the 2007 permitted ETOF and extending directly offshore between FDEP Monuments R- 97 and R-111, will be surveyed during the 2019 survey. Divers will collect qualitative video to document the seafloor and associated biota along each transect. A survey of the proposed pipeline corridor will also be conducted to verify the absence of hardbottom in this area. If any hardbottom is observed, it will be qualitatively assessed in the same manner as previously described. 1.4 Data Analysis and Reporting: Findings from the Task 1.2 desktop analysis and the Task 1.3 in situ survey will be summarized provided by CSA in a habitat characterization report and as a habitat characterization map. The habitat characterization map will be (a) based on the preliminary desktop work and the reconnaissance and side scan surveys, and (b) will be supplied as a collection of shapefiles. The habitat characterization report will be based on the data gathered during the surveys and the data presented in the habitat characterization map. The report will include methods, results, and discussions regarding hardbottom habitat, community types, and locations within the project area. The habitat characterization report will include figures documenting the survey transect positions with the location of hardbottom and substrate types along each survey line, qualitative survey video, digital images, and drawing files showing transect locations and substrate type in ArcView format. The habitat characterization map will be provided as a collection of shapefiles.
