Any such conflicts between the RFP and the identified standardor provisions shall be brought to the attention of the Contracting Officer Representative (COR)requesting direction.The project will consist of the design and construction of an upgraded irrigation diversionstructure on Johnson Creek and enclosed conduit to convey diverted water down theirrigation canal in segments not currently enclosed in pipe. The diversion structure needs tomeet federal and state fish passage and screening criteria, allowing unimpeded fish passagein Johnson Creek and excluding all fish from the irrigation canal/pipeline. The diversionmust be capable of diverting Johnson Creek streamflow down the canal while leaving a targetof 1.0 CFS of flow in Johnson Creek during the period of diversion per the attached MOA.The conduit installed in the canal shall be capable of conveying the greatest amount ofdiverted flow possible while utilizing the segments already enclosed in pipe.
