Recent design conditions will be'required for the purposes of submitting the Joint Coastal Permit application to FDEP. The following services will be provided to update the design on recent conditions and draft a design update memorandum to supplement the Joint Coastal Permit (FDEP) and ENG 4345 (USACE) applications. Task 1: Scooe of Work The Sector 5 beach fill templates, initially designed based on the March 2017 conditions (Feasibility Evaluation Report, 2017), will be updated based on the updated November 2017 conditions. It is assumed that the November 2017 beach profile survey data collected by Morgan & Eklund, Inc. and provided by the County is considered final, has been processed and does not require additional review. The dune position and berm width for each profile will be reevaluated to ensure the design intentions are still met (i.e. upland protection, no hardottom impact, recreational beach, etc.). Minor adjustments to the dune position and/or berm width may be made, as deemed appropriate based on recent conditions. The required design fill volume will be recalculated and equilibrated profiles will be developed at each R -monument within the project area based on the recent beach condition. An estimated equilibrium toe of fill (ETOF) will be determined at each profile. Task 1: Deliverable A design update memorandum will be developed to briefly describe the fill template and the need for the update. The memorandum will make reference to the Feasibility Evaluation Report, which was the project's initial design document. included will be a summary table describing the template dimensions and required fill density at each R -monument. Also included will be profile plots portraying the recent November 2017 beach conditions, the updated design template, and the estimated equilibrated fill profile. Maps depicting the estimated ETOF and available hardbottom edge delineations (see Task 2) overlain on the most recent aerial photography (collected in July 2017) will also be included. Task 1: Schedule APTIM will provide the deliverable within 30 days of the notice to proceed with this task or Task 2, whichever is later. Task 1: Cost The lump sum cost for Task 1 is $4,398.00. Task 2: Hardbottom Edge Delineation Per discussion with FDEP regarding permitting efforts, several years of aerial -delineated hardbottom edge positions can be used to evaluate if the hardbottom resources are stable over time in the Sector 5 project area. The hardbottom edge conditions will be submitted with the JCP application to support the no impact project design. The County has provided georeferenced aerial photographs from 2007 and 2017, along with previously delineated aerials from 2015. If the edge is shown to be stable over time, FDEP has indicated that in -water verification of the edge may not be required as a Request for Additional Information (RAI) item, but may instead WO#23: Sector 5 Permitting and Construction services Proj. #636232224 100
