Board approves 9th amendment to Tetra Tech agreement for Gila Valley watershed planning

The Graham County Board of Supervisors voted Aug. 18 to approve the ninth amendment to a professional services agreement with Tetra Tech related to the Gila Valley Watershed environmental assessment and plan, Engineering/Planning staff told the board. Eric Engel, representing planning and engineering, presented the item and described the project as long‑running and largely grant‑funded. A supervisor noted nine amendments is a substantial number but said the grant funding and the project's duration make the amendments reasonable and expressed support for completion. Why it matters: The Gila Valley Watershed plan relates to watershed management and infrastructure planning that affect county roads, drainage and long‑term land use in the valley. Grant funding suggests the scope and cost are at least partially supported by outside funds. Board action: A supervisor moved to approve the ninth amendment; another seconded, and the board approved the amendment by voice vote. Implementation and context: Staff said the contract amendments reflect a long project history and that the board encouraged completion and the final report. No contract dollar amounts or specific amendment terms were read into the public record at the meeting. Next steps: The planning/engineering team will continue design and finalize the watershed report under the amended professional services agreement.
