The scope of work described herein is to support the County for Year 1 physical <br />monitoring reporting, as required by permit. <br />The tasks to perform this work are listed below and described on the following pages. A breakdown of <br />the hours and expenses to develop the cost is attached. The scope and fee proposal were developed <br />following the provisions of the Professional Services Agreement between Indian River County and <br />APTIM, dated January 9, 2018, to provide engineering and biological support services in support of the <br />Sector 3 (Wabasso Beach) Beach and Dune Restoration Project (RFQ#2018006). <br />Year 1 Physical Monitoring Report <br />Volumetric and contour changes at the Sector 3 Beach will be calculated using surveys that were <br />collected at the FDEP R -monuments by the County's surveyor, Morgan & Eklund. APTIM will review the <br />data to ensure that it conforms to the standards required by the FDEP physical monitoring plan. APTIM <br />will notify the County of any issues with the survey data and will coordinate through the County or directly <br />with the surveyors to resolve any issues. <br />APTIM will develop an engineering report that discusses the performance of the beach fill project. Beach <br />contour changes will be evaluated to document changes at the shoreline and the dune. Volumetric <br />changes will be quantified above MHW (+0.6 ft NAVD) and above the depth of closure. All computations <br />and distinguished erosion and accretion patterns/trends will be summarized with tables and graphical <br />representations in addition to plots of the survey profiles. <br />In accordance with the JCP requirements, the report will specifically include the following: <br />A record of the volume and location of all beach fill material placed within the project area <br />2. The volume and percentage of advance nourishment lost since the last beach nourishment project <br />as measured landward of the MHW line of the most recent survey <br />85 <br />
