Staff also requests that the Board authorize staff to pursue any and all grant/funding opportunities for this project. BACKGROUND: The Choctawhatchee Bay shoreline along Veteran's Park is experiencing long term chronic erosion. This erosion is responsible for loss of valuable property with the resultant loss of recreational opportunities and loss of upland resources and habitat. Staff proposes a "soft", living shorelines approach to counter this erosion. This approach has been successful in countless areas and will create educational and tourism related opportunities as well. Also, in beginning the permitting process we can position this project in a more favorable position for National Resource Damage Assessment, RESTORE and other funding opportunities. OPTIONS: Approve/Disapprove RECOMMENDATIONS: Approve and authorize the Chairman to sign Task Order #1, contract C14-2117-TDD with Taylor Engineering in the amount of $106,108.00 for the preliminary design and environmental permitting of the Veteran's Park living shoreline project and authorize staff to pursue grant/funding opportunities for this project.

HOSHTHARA PRINT NAME 12 for [13 DATE EXHIBIT A Scope of Work For OKALOOSA COUNTY PROJECT GREENSHORES PHASE I PRELIMINARY DESIGN AND ENVIRONMENTAL PERMITTING ASSISTANCE INTRODUCTION Taylor Engineering presents this scope of work and cost estimate to Okaloosa County (“County”) for coastal engineering analysis, preliminary engineering design, and permit application assistance to pursue regulatory authorizations for Phase I of the Project Greenshores conceptual design. Phase I of the conceptual design includes all water-dependent improvements — offshore breakwaters/oyster reefs, public access pier, existing dock expansion (Marler Park Boat Ramp), water access features (e.g., kayak launch), and salt marsh restoration. Taylor Engineering staff met with the Florida Department of Environmental Protection (FDEP) and U.S. Army Corps of Engineers (USACE) staff on July 11, 2013 to discuss the proposed project and potential permitting requirements for the first phase. Following this meeting, Taylor Engineering performed background data collection and natural resource investigations to further refine the project conceptual design. This scope of work addresses the analysis, design, and permitting requirements as discussed with regulatory staff. ASSUMPTIONS We have developed this scope of work with the following assumptions: « Access to the proposed improvements will be through the existing Marler Park. * A concrete floating dock/breakwater will comprise the proposed public access pier. * Project design and permitting will not include installation of a marina fuel system or sewage pumpout facility. « The proposed improvements will not require dredging or underwater debris removal. « The proposed access pier design will not require or include construction of a shoreline bulkhead structure. « Wetland delineation and habitat characterization work will only include the shoreline and wetland areas in the immediate area of the proposed shoreline restoration. « The permit application will not include any upland development component. Therefore, the FDEP will receive and initially review the application. The FDEP will determine whether FDEP or the Northwest Florida Water Management District (NWFWMD) will ultimately provide final permit review. Given the water-dependent features, we assume FDEP will provide permit review and processing. ¢ Based on our preliminary conversations with FDEP, we assume water quality testing will not be required. ¢ Okaloosa County will be responsible for regulatory fees associated with the permits or permit application reviews. If any of these assumptions prove incorrect, we reserve the right to modify our scope of work and associated costs. ITEMS SUPPLIED BY COUNTY Taylor Engineering assumes the County will provide the following additional documents: A-1 * Digital property boundary survey in AutoCAD format including riparian lines, topography, bathymetry (if available), and any surveyed wetland lines with the same survey data in hardcopy form certified/sealed by a Florida-licensed Professional Land Surveyor. * Digital master plan drawings of the County property in AutoCAD format showing all leased property boundaries, existing uses, conservation/protected areas, proposed improvements, etc. * Copies of existing regulatory authorizations associated with the project site or proposed improvements (e.g., Marler Park Boat Ramp, Marler Park Boat Parking Improvements, etc). * Copies of existing County easements across neighboring properties between the proposed project site and the Gulf Islands National Seashore (GINS). * Any available additional studies, investigations, or preliminary designs completed for the County property. * Any available geotechnical soil borings collected for construction projects on County property, whether on land or in water. If any of the above items are unavailable and engineering design or permit applications require such items, Taylor Engineering may prepare an additional scope of work and fee request to collect the necessary supporting data or complete the required supporting studies. The following tasks comprise this scope of work. TASK 1 — Coastal Conditions Analysis Taylor Engineering will prepare a coastal conditions analysis to define key design parameters at the proposed project site. The first step in the analysis will be to compile existing site-specific information such as tidal datums, storm surge elevations, historic wind records, and existing bathymetric data. We will use this information to estimate the wind-generated waves at the site for varying-level storm events based on empirical wave modeling. The results of the study will provide critical design parameters for varying- level storm events. The analysis will provide the information necessary to optimize the waterfront structures (€.g., Orientation, crest heights, etc.) and allow the County to accurately assess the risks associated with varying design conditions. TASK 2 — Hydrodynamic Assessment FDEP has stated in preliminary consultations that they will likely require a hydrographic assessment to demonstrate that tides and currents reduce the concentration of a conservative pollutant introduced into the project area by 90% within 96 hours. Taylor Engineering will further refine its existing in-house hydrodynamic numerical models of the area and the adjacent waters to predict whether a potential pollutant released within the proposed project area will meet the State’s criteria. The modeling analysis will include a field effort to record tidal elevations and tidal velocities; this field work will support calibration of the model as necessary to validate our results to the permitting agencies. We assume FDEP will accept model calibration based on recorded current measurements. The hydrodynamic modeling will also take into account the proposed breakwater structures. Taylor Engineering will complete the required hydrographic assessment and prepare a report summarizing the findings. The report will serve as a key component to the permit application. We will confirm the requirement for this study at the pre-application conference. If the lead state agency does not require this study, we will submit a change order to eliminate the hydrographic assessment from the scope of work. A-2 TASK 3 — Coastal Engineering Analysis In addition to the hydrodynamic assessment under Task 2, FDEP has also stated numerical wave and sediment transport modeling will likely be required to estimate the proposed breakwater structure performance and the resulting sediment transport response landward of the structures. As such, Taylor Engineering will perform additional hydrodynamic simulations of the proposed breakwater structures and project area to determine the change in the sediment transport potential resulting from the structures. The results of the investigations will provide FDEP with necessary information regarding the potential changes resulting from the proposed structures. Taylor Engineering will also develop a CGWAVE wave evolution model for the project area. CGWAVE is a U.S. Army Corps of Engineers (USACE)-developed finite element wave propagation model that includes wave refraction, diffraction, and reflection processes in the solution. The model will provide insight into wave transformation effects along the project site and provide critical information for the offshore structure design. We will prepare a design document summarizing the modeling procedures and results of the sediment transport potential and wave propagation modeling. TASK 4 — Preliminary Engineering Design and Permit Drawings Based on the results of previous background data collection, natural resource investigations, and Tasks | - 3 above, Taylor Engineering will develop a preliminary design for the Project Greenshores in-water structures and waterfront components. We anticipate this preliminary design to consist of a pile-supported dock extension near the existing boat ramp; a combination floating pier/breakwater, a pile-supported pier shore connection, and a gangway to connect the fixed pier to the floating pier/breakwater; offshore rock breakwaters/oyster habitat; and the saltmarsh restoration areas. In addition, the County desires an additional waterfront access structure (e.g., kayak launch area) which we anticipate to have minimal structural components. Based on regulatory guidance, we will design the structures and
