(CONSULTANT), dated December 6, 2011, and the Extension and Amendment of Continuing Contract Agreement for Professional Services, dated November 4, 2014, hereafter referred to as the Contract. PROJECT UNDERSTANDING Each year the COUNTY is required to document financial assurance in accordance with Solid Waste Operations Permit. CONSULTANT assists COUNTY with the financial assurance reporting that is submitted to the Florida Department of Environmental Protection (FDEP) each year. The Scope of Work is as detailed below. CONSULTANT will coordinate with the COUNTY to provide timely execution of each portion of this project. TASK 1- FINANCIAL ASSURANCE The COUNTY operates a Class I and construction and demolition (C&D) debris landfills through a contract with Republic Services. The COUNTY is required by Chapter 62-701, F.A.C. to provide financial assurance for each of these facilities annually. Subtask 1.1- Financial Assurance Report CONSULTANT will prepare documentation that demonstrates proof of financial assurance for the cost of closing and providing long-term care for the Class I landfill, the C&D debris landfill, and the waste tire site. This documentation will be submitted for review by the COUNTY. Two copies of the final document will be provided to the COUNTY. CONSULTANT will meet with the COUNTY up to four times to discuss issues and to provide needed coordination. CONSULTANT will also respond to FDEP correspondence regarding financial assurance. Subtask 1.2 - Survey and Airspace Assessment CONSULTANT will provide surveys and assessments of consumed airspace performed by, a subconsultant, Masteller, Moler, Reed & Taylor, Inc. for the Class I and C&D Landfills. The survey work for the Class I waste area will include a complete topographic survey of Segments I, II, and III as well as the ditches and roadways surrounding the Class I area. The topographic survey of the C&D debris landfill site will include the waste area, as well as the fence -line and the surrounding ditches and berms adjacent to the C&D debris site. CONSULTANT will review the volumetric modeling and include a summary of estimated waste density based on the results of the survey and volumetric modeling. A-1 jj1636.doa The deliverable from Masteller, Moler, Reed & Taylor, Inc. will consist of a survey identifying the dates the field survey was completed. Airspace consumed and remaining airspace based on the survey and the construction and design criteria shall be specifically identified in the financial assurance report. The survey shall also include the results of the volumetric calculations for the Segments II and II1 portions of the Class I landfill, as well as the C&D debris landfill. Deliverables accompanying the survey shall include: A 1 -inch = 50 feet scale contour map for each site with 1 -foot contour intervals in regular weight lines, and 5 -foot contour intervals in bold weight lines. Signed and sealed contour maps will be provided on 24 -inch by 36 -inch paper of each landfill site in 1 -inch = 200 feet scale. A Compact Disc (CD) with ASCII file of the survey data in AutoCAD 2004 will also be provided. For the Class I Landfill (Segment I, II, and II1), the financial assurance report shall include an evaluation of the compaction of the waste and an analysis as to whether Republic Services is meeting its contractual compaction requirements. CONSULTANT will include escrow account balance recommendations for Fiscal Year 2014-2015, as well as escrow account budget recommendations for Fiscal Year 2015-2016.

The footprint of the oyster reef measures approximately 75 ft. by 150 ft. with the long axis being oriented in a north -south direction or perpendicular to the direction of flow from the FDOT ditch. This oyster reef is a three dimensional structure constructed using concrete rubble that ranged in size from approximately 1.0 ft' to pieces approximately 13 ft' in size. A wire mesh foundation was used to minimize settling of the concrete rubble into the underlying sediments. The oyster reef generally extends up into the water column to a point approximately 0.5 ft. below the mean low tide elevation. The concrete rubble was hand stacked to maximize the volume of void space between the individual pieces of concrete. The resulting reef structure was distributed over an area of approximately 0.25 acres, while the estimated area of exposed concrete surface available for colonization by encrusting organisms was approximately 0.81 acres. The project objectives for constructing the oyster reef were defined as follows. 1. Create a three dimensional hard surface submerged structure in the Indian River with a relatively high surface area within a limited space that provides potential habitat for encrusting organisms such as oysters. Macro encrusting organisms (such as oysters, barnacles, and serpulid tubeworms) form the base of the food chain (for fish, crab, and shrimp species), and can provide micro refugia for certain larvae and juvenile fish species, and can provide significant additional surface area and micro -habitat for other attached organisms such as algae species that will modify water quality conditions within and around the reef. Oysters also can directly modify water quality conditions within and around the reef structure. 2. The concrete rubble was hand stacked to create void spaces throughout the reef structure of differing sizes, dimensions, and openings to the Indian River. These void spaces were intended to provide refugia for juvenile fish species and crustaceans (such as crab and shrimp species). The relative significance of the void space in the reef design was predicated on a working hypothesis that predicted the biomass of potential food items associated with the reef would be significantly greater (on a g/m2 basis) than any other area in the general vicinity of the reef, including the mangrove communities along the shoreline. A logical extension of the hypothesis then predicts the biomass of game fish including the reef in their home range, or that will be found over, within, or around the reef will be significantly greater than other nearby areas within the Indian River including nearby seagrass beds, if any. 3. Establish a relatively dense oyster population on the surface of the exposed concrete rubble. This oyster population will facilitate the removal of nitrogen from the water column flowing Page 1 of 4 across the reef. The oyster reef is located east of the FDOT ditch discharge point to the Indian River, and therefore, stormwater discharged from the FDOT ditch will flow across the reef. It is expected the oyster population on the reef will remove a significant fraction of the nitrogen load discharged from the FDOT ditch on an annual basis. 4. Oysters were expected to form a dense population on the reef. Oyster spat were expected to colonize and overgrow both living oysters and dead oysters shells, thereby creating a significant mass of dead oyster shells through time. The working hypothesis here was the oyster population will facilitate the removal of phosphorus from the water column flowing across the reef. The accumulation of dead oyster shells will form a long term phosphorus sink within the reef. A detailed survey of the encrusting organisms on the reef was conducted in late December 2013. The results of this survey are summarized below. Estimated Number Species Within Reef Area Anemone 8,500 Barnacles 102,000 Mussels 8,500 Oysters 476,000 Sea Squirts 85,000 Serpulid Worms 4,488,000 A second survey was conducted in July 2014 to estimate the oyster and serpulid worm populations on the reef. The second survey indicated there were 564,000 to 728,000 oysters (95% confidence interval) on the reef structure. The survey also estimated serpulid worm population ranged from 4,969,000 to 5,614,000 individuals (95% confidence interval) on the reef. The oysters generally ranged in size from approximately 1.0 cm to approximately 6.35 cm. The outer surface of the oyster shells were 100 percent covered by other encrusting organisms such as other oysters, serpulid worms, mussels, and periphytic algal species. This data indicates that the colonization rate of encrusting organisms appeared to be moving toward achieving Objective 1. A preliminary survey of the organisms found within the void spaces in the reef also was conducted in late December 2013. One problem noted during this survey was the difficultly in accessing and assessing the species found in these areas. Therefore, the results of this part of the reef assessment definitely under estimated the diversity and density of the species in these areas. The survey did show that stone crabs have colonized the reef, and the estimated population at this time were 728 individuals. Juvenile mangrove snapper also were found within the void spaces, however, it was not Page 2 of 4
