Big Creek Dam Alternative Analysis

The City of Newport, Oregon is seeking a professional consultant to conduct a comprehensive Alternative Analysis for the Big Creek Dam project, located in Klamath County. The procurement is structured as a Request for Proposals (RFP) to address two existing earthen dams identified as unsafe by the state dam engineer. The primary objective is to develop a strategic alternatives analysis for replacing or repairing the dams, which serve as the sole water source for the Newport community. Specific deliverables include data gathering, site investigation, developing a comprehensive alternatives analysis, and preparing a final report that evaluates potential solutions such as wells, desalination, potable reuse, constructing a new dam on Rocky Creek or Siletz River, or various repair/replacement options for the existing Big Creek dams. The proposal must provide detailed construction cost estimates, project timelines, and a comprehensive assessment of advantages and disadvantages for each potential solution, with a focus on meeting the city's water supply needs for a 50-year planning horizon. Proposals are due by 2:00 PM on June 4th, 2025, with an anticipated contract approval date of July 7th, 2025, and an expected project completion timeline of 6 months after contract approval.

While no specific set-aside designations or enterprise restrictions are explicitly mentioned, the project has significant financial backing, with funding already secured from state and federal sources for the design phase through 100% completion. The estimated project cost approaches $200 million, indicating a substantial investment in infrastructure improvement. HDR, Inc. has previously been involved in the project, having completed a 30% design for a roller-compacted replacement dam, which provides a foundational context for the current procurement. The city requires a consultant with extensive expertise in dam engineering, water infrastructure alternatives analysis, and the technical capability to evaluate complex water supply solutions. Potential respondents should demonstrate strong qualifications in civil engineering, hydrological assessment, and infrastructure planning, with the ability to provide a comprehensive and forward-looking analysis that addresses both immediate safety concerns and long-term community water supply needs.
