<br /> <br />Memorandum <br /> <br />TO: Mr. Bruce Woody <br /> Orange County Solid Waste <br /> <br />FROM: C. Tyrus Clayton, Jr., PE <br /> Regional Growth Leader <br /> <br />DATE: June 23, 2023 <br /> <br /> <br />SUBJECT: Orange County Regional Landfills <br />2023 C&D Landfill Annual Survey and Airspace Analysis <br />Proposal for Survey & Engineering Services <br /> <br /> Draper Aden Proposal No. TBD Lump Sum Fee = $7,000 <br /> (2021 PN: 2100778) <br /> <br /> <br />At your request, Draper Aden Associates (DAA) is pleased to offer this proposal for Aerial Services for <br />the Construction and Demolition (C&D) landfill located at the Orange County Regional Landfill Facility <br />on Eubanks Road in Chapel Hill, NC. This proposal outlines our understanding of the project scope, <br />tasks to be completed, assumptions underlying our fee proposal, and fees for the project. <br />PROJECT DESCRIPTION: The project consists of aerial survey services using a drone and conventional <br />survey to produce a topographic survey of the C&D landfill. Data gathered will be used to conduct an <br />analysis of the airspace used within Phase 1 and 2 of the C&D landfill. <br />SCOPE OF SERVICES <br />Surveying: DAA will conduct an aerial topographic survey with an sUAS /drone aircraft of the area <br />associated with Phase 1 and 2 of the C&D landfill unit, approximately 15 acres. An FAA licensed <br />Remote Pilot will conduct flight operations in accordance with FAA rules and regulations. Aerial flights <br />are dependent on safe weather conditions. The topographic survey will include setting and locating <br />Ground Control Points and performing check point measurements. The images collected using the <br />sUAS will be photogrammetrically processed to make a 3D Point Cloud and orthomosaic image of <br />the entire project area. A draftsman will use the photogrammetric output to generate the earth <br />surface and contours at one-foot intervals. <br /> <br />Analysis: DAA will provide an estimate of the total volume of air space used at the C&D Landfill on <br />Eubanks Road. In order to complete this task, DAA will use the survey produced in the task above, to <br />compare to the design base grades of the landfill to the permit air space limits to determine the <br />amount of fill that has been placed since the landfill’s inception and also since the 2021 annual <br />DocuSign Envelope ID: 0BF5502D-6C7A-4BDA-A6E0-00E9EAF0A761
