SUBJECT: Resolution 2005 - Relating to executing a Proposition 40 Phase II
grant agreement with the State Water Resources Control Board
ISSUE:
• Should the City execute a Proposition 40 Phase 11 grant agreement from the State
Water Resources Control Board in the amount of $625,000 to implement the Newport
Island Channels Circulation Improvement Project?
RECOMMENDATION:
Adopt Resolution 2005- _ authorizing the City to execute an agreement with the
State Water Resources Control Board under the Proposition 40 Phase It - 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:

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.
