Indian River County Work Order Number — 2023051-01 Sector 4 Beach and Dune Restoration Project Exhibit 1 - Scope of Work Exhibit 1 Scope of Work Sector 4 Beach and Dune Restoration Project Conceptual Design, Pre -Application Meeting, and Public Outreach Introduction: The 'Indian River County Beach Preservation Plan Update" (Plan, dated June 2020) defines the limits of Sector 4 as from Florida Department of Environmental Protection (FDEP) Reference Monument R-55 (about 3/4 mile south of the northern limit of John's Island) to R-70 (about 2,000 feet north of the County's Tracking Station Beachfront Park). The 2019 BPP identifies that prior to 2005, Sector 4 experienced an accretional trend; however, an erosional trend of 1.7 ft/yr was experienced from 2013 to 2019. To offset recent erosional trends, private entities have performed emergency dune restoration projects following significant hurricane events. The dune system within Sector 4 and elsewhere within the Treasure Coast were most recently damaged by Hurricane's Ian and Nicole in 2022. This Work Order provides services in support of conceptual design, pre -application meeting with regulatory staff, and a public outreach meeting to support a dune restoration project within Sector 4. It is our understanding that the Sector 4 Dune Restoration Project is intended to only place sand above the mean high water line to avoid the FDEP and USACE requiring the COUNTY to perform nearshore hardbottom monitoring which is typical for beach restoration projects proposed in close proximity to nearshore hardbottom. The work is proposed to be performed by Coastal Technology Corporation (Coastal Tech). Task 1 — Design - Conceptual: Coastal Tech will meet with the County to identify the County's specific objectives and design criteria for the Project. The County will provide available historic hydrographic beach profile surveys of the Project area including the most recent survey data conducted in the fall of 2022 or summer 2023 following Hurricanes Ian and Nicole. The surveys are expected to be accepted by FDEP for a pre -construction survey. The County will provide records of prior nourishment efforts performed by the County and by upland property owners. It is our understanding that the County is seeking an FDEP Coastal Construction Control Line (CCCL) and USACE Nationwide permits for authorization of the work. Informally, FDEP staff have identified a Joint Coastal Permit could be a more desirable method of FDEP authorization. The design effort is intended to provide the information required for a USACE Nationwide Permit Authorization and FDEP CCCL Permit Authorization. If the USACE or FDEP require additional design information, we can provide this additional information as an additional service to the County under separate authorization. Page 1 of 3 August 22, 2023
