The project was constructed in three phases and the analysis will account for the phased construction. Furthermore, <br /> 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 at <br /> individual and cumulative shoreline and volumetric changes. During our.review of previous reports, we noted that <br /> volumetric changes were calculated above MHWL; MHWL to -12 feet NAVD; above-12 feet,NAVD; -12 feet to - <br /> 25 feet, NAVD; and above -25 feet, NAVD. CPE will review the data and historic basis for calculating volumetric <br /> changes to this depth given the presence of nearshore hardbottom. If appropriate,CPE may propose alternate depths <br /> to which to calculate volumetric changes. <br /> CPE will collect aerials of the project area as discussed more fully later in this scope of work. The aerials will be <br /> collected from R-15 through R-60. Plots of hardbottom change and shoreline position will be overlaid on the aerials <br /> and included in the report appendix. <br /> The FDEP approved physical monitoring plan requires that sand samples be collected during summer months <br /> rnMr-idem with 24-month post-construction monitoring event at four beach profile transects (R-22,11-30, R-41 2nrl <br /> R-52). However, sand was only placed between R-20 and R-36 in Phases 2 and 2B. Therefore, only R-22 and R-30 <br /> will be sampled and analyzed. Five samples will be collected and analyzed along each transect(toe of dune,mid-berm, <br /> MHW, MLW, and -3 feet, NAVD) for a total of 10 samples analyzed. We understand that Morgan & Eklund will <br /> collect these samples and ship them to us for analysis. CPE has a certified laboratory required by FDEP standards to <br /> analyze beach samples. We will follow the FDEP protocols for sieving the samples using 20 sieves ranging in size <br /> from-4.25 phi to +4 phi at'/2 phi intervals. A cumulative frequency distribution and frequency distribution histogram <br /> will be 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 /> CPE will submit a draft of the report of the County for review and comment. This will be submitted electronically <br /> (PDF). CPE will incorporate comments from the County and revise the report accordingly. CPE will then submit <br /> two hard copies and an electronic copy to the FDEP. CPE will submit one hard copy and one electronic copy (PDF) <br /> to the County. <br /> Required Data <br /> To perform the physical monitoring evaluation,CPE will need the following data: <br /> • Survey data in x,y,z format collected in January 2010, September 2010,July 2011, May 2012, and July <br /> 2012. <br /> • Design cross-section in electronic format. <br /> • Shape file or Auto CAD file of the landward edge of hardbottom for previous monitoring events. <br /> Schedule <br /> The draft monitoring report will be completed within 60 days of receipt of the survey data from Morgan &Eklund. <br /> We estimate that the county will review and provide comments on the document within 2 weeks. CPE will revise the <br /> 2481 NW BOCA RATON BOULEVARD, BOCA RATON, FL 33431 <br /> 561.391.8102 • FAX 561.391.9116 • COASTAL PLANNING & ENGINEERING, INC., A CB&I COMPANY 50 <br />
