Indian River County Work Order Number 2 Beach Preservation Plan Scope of Work Attachment i General : The "Indian River County Beach Preservation Plan Update" (revised March 16, 1998) and the "Indian River County Beach Restoration Projects — Engineering Design Report " (by ATM dated February 2000 - hereinafter referred to as "ATM Report") addresses eight ( 8) designated planning sectors from Sebastian Inlet to the south County line and recommend periodic nourishment of the County' s critically eroded beaches . During 2004 and 2005 , County beaches were severely impacted by several hurricanes which caused significant beach erosion and prompted many dune restoration projects and seawall projects, which have provided limited protection to upland improvements. In light of these changes, it is desirable to update the County' s Beach Preservation Plan in collaboration with the COUNTY' s Beach and Shore Preservation Advisory Committee (hereinafter referred to as "Beach Committee"). in general, consistent with the existing Beach Preservation Plan and the ATM Report , it is anticipated that the updated Beach Preservation Plan produced via this Work Order, shall prescribe the limits and extent of beach/dune nourishment required to maintain County beaches. "Throughout the progress of work, COASTAL TECH will maintain informal contact with the COUNTY and FDEP staff. Informal contact includes meeting with the COUNTY ' s project manager, telephone contact, emails, written monthly progress reports to the COUNTY and FDEP and similar activities not involving special graphics or presentations, or travel outside the project area. COASTAL TECH will maintain and update an MS Project Schedule as tasks and milestones are met . Each task shall be considered complete for contractual purposes when the interim work product(s) have been reviewed and accepted by the COUNTY and FDEP staff. This Work Order includes the following tasks: Task 1 — CONDITIONS ANALYSIS Task la - Erosion Analysis : The COUNTY will provide COASTAL TECH with the following existing data in hard copy and digital form within the County: a) available controlled digital photography b) beach profile surveys c) BPP beach condition analysis report 86 ' -01 ' — (Woods Hole Group July 2002) d) natural resources maps and characterization — including hardbottom e) native beach sand sampling and analysis results f) other design documents (prepared subsequent to the ATM Report) Based upon the data provided by the COUNTY and otherwise available from the Florida Department of Environmental Protection (FDEP), COASTAL TECH will conduct a shoreline and volumetric change analysis to determine historical erosion losses along COUNTY beaches. The erosion analysis shall address changes (a) from 1972 to 1986, and (b) from 1986 to the most recent data available, shoreline change (at Oft, 5 ft, and 10 ft elevation) and volumetric change (to an agreed upon depth). The report will include tabular and graphic presentation of (a) shoreline change data (b) volume change data, and (c) historical bluff changes - for each monument. The report shall include plots of representative profiles for each sector. Task lb —Vulnerability Analysis : In general, COASTAL TECH will conduct an assessment of the risk of damage to upland property, existing structures, public infrastructure and coastal environmental resources from potential background and storm induced erosion along Counlybeaches. COASTAL TECH will conduct a field investigation to identify the extent of existing shoreline armoring including seawalls, rock revetments, and "sand-bag" structures. The likely landward extent of future erosion will be assessed for 10, 20 and 30 years into the future based upon the updated historical shoreline change data from Task Ia. COASTAL TECH will plot the predicted limits of erosion (expected bluff location) and extent of existing armoring onto available digital photography provided by the COUNTY to produce risk characterization maps .
