Tyrus Clayton, Jr., PE <br />DATE: May 11, 2026 <br />SUBJECT: Orange County Regional Landfills <br />2026 C&D Landfill Annual Survey and Airspace Analysis <br />Proposal for Survey & Engineering Services <br />TRC Engineers, Inc. No. TBD Lump Sum Fee = $11,900 <br />(2025 TRC PN 609288) <br />At your request, TRC Engineers, Inc. (TRC) is pleased to offer this proposal for Aerial Services for the <br />Construction and Demolition (C&D) landfill located at the Orange County Regional Landfill Facility on <br />Eubanks Road in Chapel Hill, NC. This proposal outlines our understanding of the project scope, tasks <br />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: TRC will conduct an aerial topographic survey with an UAV (drone) aircraft of the area <br />associated with Phase 1 and 2 of the C&D landfill unit (approximately 15 acres). The topographic <br />survey will include setting and locating Ground Control Points and performing check point <br />measurements. The lidar data derived using the UAV will be processed to generate a point cloud and <br />orthomosaic image of the project area and used to generate volumetrics and contours at one-foot <br />intervals. <br />Analysis: TRC 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, TRC 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 2024 annual <br />survey. In addition, TRC will obtain tonnage from the Client for the time period between the 2024 <br />and 2025 annual survey to assess compaction rates for the C&D facility. <br />Docusign Envelope ID: B4965394-A418-8BB5-821A-3A35E31BF87C
