ATTACHMENT A <br />SCOPE OF PROFESSIONAL SERVICES <br />INDIAN RIVER COUNTY SOLID WASTE DISPOSAL DISTRICT <br />ENGINEERING SERVICES FOR <br />SITE PLAN UPDATE <br />PROJECT UNDERSTANDING <br />On February 21, 2006 Indian River County Board of County Commissioners directed the Solid <br />Waste Disposal District to focus the next development effort to the interior of the existing <br />landfill site. This proposal provides for engineering services required to update the site plan <br />with the essential elements of the solid waste operations for continued service to the citizens of <br />Indian River County. <br />TASK 1.0 - SITE PLAN UPDATE <br />CDM will develop a site plan for SWDD that will incorporate a phasing plan for development <br />of Class I, Construction and Demolition (C&D) Debris disposal, and other solid waste <br />processing areas for the build -out of the current landfill site. The site plan will be incorporated <br />into the solid waste management master plan. The development of the site plan update will <br />address the following issues: <br />Subtask1.1 SWDD Meetings <br />CDM will work closely with IRC SWDD to develop the internal site plan. The meetings will <br />establish the design preferences for the landfill. <br />Subtask 1.2 Stormwater modeling <br />CDM will verify the ultimate size of the stormwater ponds required to accommodate state and <br />local codes and requirements. Modeling will be used to identify stormwater storage and <br />management requirements based upon proposed site usage, (impervious area, solid waste <br />disposal units, etc.) The stormwater modeling is an iterative task which will be updated with <br />the cell size established in subtask 1.3. The site plan will be developed to the level showing <br />ditches, roads, stormwater structures, pipes, waste processing, and disposal units. <br />Subtask 1.3 Airspace Balancing Calculations <br />CDM will establish the ratio of Class I airspace with the C&D capacity. This will take in to <br />account the different filling rates and volumes of the two waste disposal units and determine <br />their footprints. These calculations will be verified internally along with SWDD staff as quality <br />assurance and control. <br />Subtask 1.4 Other Processing Facilities <br />Other landfill processing facilities will be taken into account for development of the interior site <br />plan. These processes include waste tire, scrap metals, citizens drop-off areas, material <br />recycling, equipment storage, vehicle parking, and fueling facility. <br />A-1 mh2408.doc <br />
