RECOMMENDATION: Adopt Resolution 2005- authorizing the City to execute an agreement with the State Water Resources Control Board under the Proposition 40 Phase II - Watershed, Clean Beaches and Water Quality Act. DISCUSSION: This agenda item seeks the Council's permission to execute an agreement with the State Water Resources Control Board to obtain funding for implementation of the Newport Island Channels Circulation Project (Project). Newport Island Channels (NIC) is located at the west end of Lower Newport Bay, and has a limited hydraulic connection with the bay that subsequently hinders tidal flushing. City staff believe this poor circulation plays a major role in the poor water quality in this area. Beginning in 2002, City staff were directed to seek solutions to improve water quality around Newport Island. The following pilot tests and studies have been conducted to date: SWRCB Grants December 13, 2005 Page 2 • InStreem Units - pilot testing of mechanical flow enhancers (InStreem) to improve water circulation and mixing with the bay. During the 10 day test local residents and stakeholders had the opportunity to observe the InStreem unit and provide comments to the City. In general, folks believed the unit was effective in enhancing water circulation, but expressed concerns relative to noise and potential impacts to boat traffic. • Submerged Pumps - a study was conducted to evaluate the use of submerged pumps to enhance water circulation. The study concluded that submerged pumps can increase water circulation; however, they are very expensive to purchase and maintain. • Oloids - pilot testing of yet another mechanical flow enhancer (the Oloid). Similar to the InStreem an Oloid was installed to evaluate its ability to improve water circulation and mixing with the bay. However, unlike the InStreem - the Oloid (a much smaller device) was not met with objection by local residents relative to size and noise issues. Based on City's flow measurements and positive feedback from residents, City staff submitted and was awarded a $625,000 grant from the State Water Resources Control Board to purchase and install fifteen Oloids at strategic locations (as suggested by numerical modeling with final locations determined in consultation with NIC property owners) around Newport Island to circulate and improve water quality in this area. Environmental Review: A Negative Declaration is being prepared, and will be completed before installation of the Oloid device.
