Action Items
1. TAC approved the meeting summary from the June 13, 2019 and October 15, 2019 meetings with
no objections.
2. TAC carried a motion to move TAC meetings during 2020 to second Wednesday of each month
(months that a meeting is scheduled for based on LWA’s presentation) at 1 PM. This was
proposed to enhance participation and provide flexibility for the consultant team to conduct
additional meetings.
3. TAC carried a motion to create a working group based on the consultant’s suggestion for
groundwater/surface water interaction. Working group will include Laurel Marcus, Marcus
Trotta, Sean White, and Mike Webster from the TAC members and may include other members
of the public as necessary.
Notes
Agenda Item 3.
1. Meeting schedule was presented by the consultant team with meetings proposed for
January, March, May, July, September, November in 2020. Meetings will be held second
Wednesday of each month at 1 PM.
Agenda Item 4.
1. TAC did not provide any comments regarding the Hydrogeological Conceptual Model
(HCM).
Agenda Item 5.
1. Levi Paulin followed up on the status of the Technical Support Services grant. Consultant
team (Team) provided necessary information. Existing wells were inspected by the Team,
Deborah Edelman, and Sarah Dukett in a meeting a day before. Transects are being
formed and locations of new drilled well are being finalized. GSA and the Team are
hoping to instrument existing wells and have the drilling done in this Spring.
2. Review and commenting process was proposed and advantages of it was discussed. No
significant objections were made on the new process. Marcus Trotta indicated that the
same process is being successfully implemented by Sonoma Water. However, he
mentioned that public requested to be able to see the document with the running
comments for better reviewing. Sam Sandoval also spoke in agreement with the method
proposed.
3. Official forms were requested to be delivered in a timely manner for the start of review.
Agenda Item 6.
1. Discussion was provided on the missing parts of Chapter 2.1. TAC members provided
direction on where to look for contaminated groundwater and clean-up sites. Some
preliminary discussion also formed around the subject of groundwater dependent
ecosystems (GDEs) and how they will be defined and investigated in the surface
water/groundwater workgroup (workgroup). Sam Sandoval volunteered for GDE
research and attending the workgroup.
2. Results for the PRMS (Surface water model) was presented by Stephen Maples from the
Team. Results were presented to match well with observed values after calibration.
Newer version of PRMS will provide better match overall.
3. Results for the root zone budget were presented through IDC:
a. Frost protection estimation was updated based on TAC’s previous comments and
will be upgraded to be able to be used for future projection and daily climate data.
b. Comments were made by multiple TAC members regarding including Cannabis
water use in IDC and the integrated model. Team agreed on the need to do that,
but lack of accurate Land Use maps and crop use information were announced as
barriers. TAC members and the Team agreed on conducting further discussions to
represent the use more accurately in the model.
c. Estimation of Surface water and groundwater use for irrigation was presented.
TAC members indicated that groundwater use was overestimated. Ponds were
suggested to play a significant role in the irrigation and they need to be involved
in this estimation. The Team will revise the analysis based on the new
information.
d. Sean White indicated that Recycled Water will play a significant role in reducing
demand on surface water. The Team agreed and the contribution will be included
in the future projections starting from 2018.
