CB&I will develop an engineering report that discusses the performance of the beach fill project. We will analyze <br />shoreline and volumetric changes throughout the project area, identifying erosion and accretion patterns. The <br />results will be analyzed for patterns, trends or changes between annual surveys as well as cumulatively since <br />construction. The project was constructed in three phases and the analysis will account for the phased <br />construction. Furthermore, the report will compare the project performance to the stated design. <br />Plots of the survey profiles, and graphical representations of volumetric and shoreline positions for the monitoring <br />area will be presented. Summary tables of the shoreline and volumetric changes will be presented, again looking <br />at individual and cumulative shoreline and volumetric changes. Volumetric changes will be calculated above <br />+6.0 feet NAVD; MHW to +6.0 feet, NAVD; -5.0 feet, NAVD to MHW; and -12.0 feet to -5.0 feet, NAVD; and <br />landward of the approximate edge of hardbottom. The volumetric analysis will be performed similar to the 2014 <br />report to avoid introducing error in the calculations due to the nearshore hardbottom. <br />CB&I will collect aerials of the project area as discussed more fully later in this scope of work. The aerials will <br />be collected from R-15 through R-60. Plots of hardbottom change and shoreline position will be overlaid on the <br />aerials and included in the report appendix. <br />The FDEP approved physical monitoring plan permit modification requires that sand samples be collected during <br />summer months coincident with the immediate post -construction monitoring event at four beach profile transects <br />(R-22, R-30, R-41 and R-52). Although sand was only placed between R-24 and R-55 during the Dune Repair <br />Project, all four transects will be sampled and analyzed for completeness and comparison with past data sets. <br />Five samples will be collected and analyzed along each transect (toe of dune, mid -berm, MHW, MLW, and -3 <br />feet, NAVD) for a total of 20 samples analyzed. We understand that Morgan & Eklund will collect these samples <br />and ship them to us for analysis. CB&1 has a certified laboratory required by FDEP standards to analyze beach <br />samples. We will follow the FDEP protocols for sieving the samples using 20 sieves ranging in size from -4.25 <br />phi to +4 phi at 1/2 phi intervals. A cumulative frequency distribution and frequency distribution histogram will be <br />presented along with a sediment analysis summary sheet providing descriptive statistics, compositional results, <br />percent fines and Munsell Color. The grain sizes will be compared to previous sediment samples to gauge any <br />changes in grain size or color. <br />Deliverables <br />CB&I will submit a draft of the report of the County for review and comment. This will be submitted <br />electronically (PDF and MS Word formats). CB&I will incorporate comments from the County and revise the <br />report accordingly. CB&I will then submit an electronic copy to the FDEP. CB&I will submit one hard copy and <br />one electronic copy (PDF) to the County. <br />Required Data <br />To perform the physical monitoring evaluation, CB&I will need the following data: <br />• Survey data in x,y,z format collected in summer of 2015. <br />• Sand samples collected in summer of 2015. <br />• Shape file or Auto CAD file of the landward edge of hardbottom mapped in summer of 2015. <br />
