SOLANO COUNTY WATER AGENCY
FLOOD CONTROL ADVISORY COMMITTEE
MEETING MINUTES: April 23, 2015
Introductions and Public Comment: Chairman Rolf Ohlemutz called the meeting to order at
6:00pm. There was no public comment.
Approval of Agenda: The Agenda for the meeting was unanimously approved.
Approval of Minutes of December 4, 2014: The Minutes from the December 4, 2014 meeting
were unanimously approved.
Ethics Training Requirements/Status: Jeff Barich informed the Committee that Mark
Holdener (absent) needs to renew his Ethics Training certification.
Update on Small Sized Projects: Jeff Barich informed the committee that no movement had
been made on any of the Small Grant Projects since the last meeting. He also noted that the item
on the table for the Collinsville Levee District had been cancelled altogether. On the day of the
scheduled initial site inspection, the Collinsville Levee District called and cancelled all plans.
Update on Medium Sized Projects: David Okita talked about the pre-feasibility study that was
conducted for the potential Rio Vista floodwall project. SCWA and the Sacramento Area Flood
Control Agency (SAFCA) jointly funded this pre-feasibility study. This pre-feasibility study
showed that it may be too expensive to protect Rio Vista in its entirety, but it may be possible to
protect the current development in Rio Vista. This will lead to SCWA and SAFCA to apply for
a feasiblity study, on behalf of Rio Vista, once funding opportunities are announced. The City of
Rio Vista does not currently have the money to match our funds, but that will be dealt with when
the time comes.
Representatives from Solano County and the Judicial Council of California presented on a
flooding issue in the Fairfield Justice Campus. They discussed where the flooding was coming
from, and the amount of damage that comes from the flooding. They presented three (3)
different studies that have been done in the past few years to address this flooding issue. The
studies showed that protecting only the worst-off buildings would help and would be relatively
affordable. They also looked at a broader, watershed-scale approach, and this is still in the
planning stage, as it is currently much too expensive to be implemented. There was much
discussion as to how the flooding could possibly be remediated, and what options the County and
Courts could consider.
FCAC Participation in SCWA Strategic Plan: David told the Committee that SCWA is
working on a new Strategic Plan to help guide the Agency. The current Strategic Plan is
outdated, and Thomas Pate is heading a working group to implement a new Plan The Agency is
looking for representation from all areas in which the Agency works, to prioritize and determine
what needs to be done in the future of SCWA. Rolf was contacted to be a part of the new SCWA
Strategic Plan working group to represent the FCAC. However, Rolf is retiring in a week, so
will no longer be a part of this working group. The Committee voiced that they do want
representation on this working group, and unanimously voted for the new Committee chair,
Terry Riddle, to take that spot in the working group. Jeff Barich will make sure that Terry
Riddle gets the necessary meeting information for the Strategic Plan working group meeting on
May 4, 2015.
Budget for FY 2015-2016: David Okita discussed each line item in the proposed flood control
budget for FY 2015-2016. The proposed budget was unanimously approved, and will be
recommended to the SCWA Board of Directors.
Discussion of Field Trip Locations for June 25 th Meeting: Jeff Barich suggested to the
Committee to take the June field trip to downtown Napa, to have a look at the newly completed
flood control facilities that Napa has implemented. There was some discussion as to possibly
scheduling the meeting for an earlier time (rather than 6:00pm) to avoid traffic. Jeff Barich will
coordinate with the new Committee Chair, Terry Riddle, to schedule the trip.
2015 Meeting Dates: The remaining scheduled meeting dates in 2015 are June 25 th (field trip)
and December 3rd.
Next Meeting: The next meeting of the Flood Control Advisory Committee is scheduled for
Thursday, June 25, 2015 at an earlier time still to be determined at the SCWA office.

The City of Napa Project involves about seven miles of the Napa River, from
Highway 29 at the Butler Bridge on the south to Trancas Street on the North.
Napa Creek improvements extend for about one mile, from the Creek mouth at
the Napa River upstream to Jefferson Street. The geomorphic design (changing
the shape of the earth) reduces flood water levels through the use of riverbank
terracing and reconnecting the River to its historic floodplain. Removing or replacing bridges that impede flood flows and the creation of the dry bypass
channels at River and Creek oxbows are other key features of the design.
