BUTLER, CLERK The CONSULTANT Team will coordinate with COUNTY officials regarding historical erosion events and beach management activities—these communications are essential for creating a comprehensive report. The review will investigate findings from previous studies/plans, the nourishment history, historical and ongoing beach management activities, COUNTY -identified public access points, permits, survey history, available light detection and radar (LiDAR) data and historical storm and erosion events. From these data, we will create a timeline of significant events. We will obtain and summarize existing regulatory permits (federal and state) for beach -related projects. The final Technical Report will include an analysis of wind, wave, water level, and sea -level rise (SLR) projection data. We will produce a geodatabase of available geospatial data and transmit the geodatabase and documentation to the COUNTY for future use. Deliverables: One Technical Memorandum will summarize the data collection. The CONSULTANT Team will implement COUNTY comments and revisions into the final Technical Report. TASK 2 — BEACH CONDITIONS UPDATE Task 2 entails analyzing, reviewing, and summarizing the shoreline performance along the County's coastline. The CONSULTANT Team will choose which years to compare based on spatial and temporal data availability. We will focus on surveys that offer full coverage of the area of interest and are applicable to the storm vulnerability and resilience analysis work in Task 4. In Task 2, the CONSULTANT Team will review historical beach profiles and available LiDAR data summarized in Task 1 and process the data to analyze historical profile elevations, contour position changes, and volumetric trends. The CONSULTANT Team will plot and analyze the beach profiles and note significant changes to beach features such as the dune and berm—with trends reported on a sector -by -sector basis. For the contour position and volume change analyses, the CONSULTANT Team will compare a minimum of three and a maximum of four surveys to generate beach trends over near-term and long- term periods; the CONSULTANT will discuss the comparison periods with the COUNTY prior to completing analyses. The final Technical Report will include a tabular and graphic presentation of the data for each R -monument in the County. The CONSULTANT Team will also predict beach recession and volume loss due to two SLR estimates over the next decade using methods published by USACE. Through discussions with the COUNTY Project Manager, the CONSULTANT Team will provide guidance and receive concurrence on which SLR trends to apply. This analysis will not include sediment transport modeling or create a sediment budget; however, the CONSULTANT Team will review previous sediment budgets and may leverage them within this study.
