The City of Newport (City), Oregon is located on the central Oregon Coast at the mouth of the Yaquina River. The City has approximately 10,000 permanent residents and many vacation properties and seasonal visitors. In addition, the City of Newport hosts a significant fishing industry, the Rogue Brewery, and a large marine research community including the NOAA Pacific Fleet Headquarters, Hatfield Marine Science Center, and the Oregon Coast Aquarium. Additional information on the City of Newport is available on the City of Newport's webpage: http://www.newportoregon.gov and at the City of Newport Chamber of Commerce web page: www.newportchamber.org The City of Newport has been working on a Big Creek Dam Replacement Project since 2011. The Big Creek Dam Replacement Project would replace the two existing earthen Big Creek Dams that have been deemed unsafe by the Oregon Department Water Resources Department, Dam Safety Program and are at risk of failure, either due to structural deficiencies or during a seismic event. The new singular roller-compacted dam would enlarge the upper Big Creek Reservoir and replace both dams with a single dam, free of structural vulnerabilities that will ensure that the City has a reliable source of water for the community’s future. The two dams are the sole source of water for the entire community of Newport. The City has hired a consultant, HDR, Inc. to complete the design for the replacement dam. The design is currently at the 30% stage. The city has secured funding from the State and Federal government for design through the 100% stage. A construction estimate was prepared for the 30% design and now the City needs to secure funding for construction of the Dam, which is currently has an estimated cost approaching $200M. An Alternative Analysis was completed in 2015 by HDR, Inc. A roller-compacted replacement dam was the preferred alternative at that time to replace the two existing earthen dams. Due to the age of the Alternative Analysis and the increasing cost estimate, the City desires to have the services of a professional consultant to develop and assist in preparing an Alternatives Analysis to provide and updated analysis on solutions for a safe, reliable, and feasible water supply consisting of resilient system components that can continue to supply clean water in the event of dam failure caused by existing structural deficiencies or natural disasters.
