Subject: Discussion and Possible Action Regarding Member Agency Dues for Fiscal Year
2020-2021
Consent Agenda Regular Agenda Noticed Public Hearing
Summary:
The board will review the current financial status of the Agency and consider dues for Fiscal
Year 2020-2021 to fund the Agency administration as the Groundwater Sustainability Plan is
developed.
Recommended Action:
Approve the assessment for three thousand dollars ($3,000) in dues for member agencies to
fund the Agency for Fiscal Year 2020-2021 and 2021-2022.
Background:
In order to provide the needed capital to initially fund the Agency, there was a contribution from
Members Agencies in the amount of five thousand dollars ($5,000). The Joint Powers Agreement
(JPA) section 15.2 allows the Agency to be funded through additional contr ibutions by all
members of the Agency.
The current amount in the trust account is $7,678.64. Based on projections for the end of the fiscal
year, staff believes there will be an account balance of $3,700. Additional funding will be needed
for next fiscal year. In March 2020, the Groundwater Sustainability Plan (GSP) Financial
Evaluation process will start. The evaluation will provide recommendations on long-term funding
options for plan implementation.
Staff recommends the member agencies provide contributions of $3,000 to fund the GSA for the
next two fiscal years. Allowing for the completion of both the GSP Financial Evaluation and
adoption of the GSP. If approved, the member agencies will receive an invoice of $3,000 at the
start of next fiscal year (July 2020).

Summary:
The Board will receive a presentation regarding Proposition 68 grant application to support the
development of the Ukiah Valley Groundwater Sustainability Plan.
Recommended Action:
Receive update regarding the Proposition 68 solicitation for Groundwater Sustainability Plan

competitive grants.
The Proposition 68 SGM Implementation Grant solicitation is anticipated to open in early 2020.
At least $88 million will be available for competitive grants for projects that address drought and
groundwater investments.
The Proposition 68 solicitation was be released on September 9, 2019 and was slated to close on
November 1, 2019. Due to the fires in Northern California and the widespread Public Safety Power
Shutoff the Governor declared a statewide emergency resulting in DWR extend the submission
date to November 15 at 1pm.
The Mendocino County Water submitted an application for funding. The Ukiah Valley Basin GSP
Development Support application is recommended for full funding in the amount of $1,23,800.

Initial Exploration of a Sustainability Goal

“Each agency shall establish in its Plan
a sustainability goal for the basin that
culminates in the absence of
undesirable results”

DRAFT
Initial Exploration of a Sustainability Goal
1.If groundwater is sustainably managed in
Ukiah Valley, what has it achieved and what
does it look like?
2.What does the worst-case scenario look like in
Ukiah Valley if groundwater is not managed
sustainably?
3.Give us your perspective but also think about
how others view the issue?

Examples of Sustainability Goals from
Other GSPs

◼Mid-County Santa Cruz GSP:
⚫Manage the groundwater Basin to ensure beneficial uses and users have
access to a safe and reliable groundwater supply that meets current and future
Basin demand without causing undesirable results to:
➢Ensure groundwater is available for beneficial uses and a diverse
population of beneficial users;
Protect groundwater supply against seawater intrusion;
➢Prevent groundwater overdraft within the Basin and resolves problems
resulting from prior overdraft;
➢Maintain or enhance groundwater levels where groundwater dependent
ecosystems exist;
➢Maintain or enhance groundwater contributions to streamflow;
➢Support reliable groundwater supply and quality to promote public health
and welfare;
DRAFT
Examples of Sustainability Goals from
Other GSPs
26
◼Mid-County Santa Cruz GSP (cont.):
⚫Manage the groundwater Basin to ensure beneficial uses and users have
access to a safe and reliable groundwater supply that meets current and future
Basin demand without causing undesirable results to:
➢Ensure operational flexibility within the Basin by maintaining a drought
reserve;
➢Account for changing groundwater conditions related to projected climate
change and sea level rise in Basin planning and management;
➢Do no harm to neighboring groundwater basins in regional efforts to
achieve groundwater sustainability.
◼Salinas GSP:
⚫The goal of this GSP is to manage the groundwater resources of the 180/400-
Foot Aquifer Subbasin for long-term community, financial, and environmental
benefits to the Subbasin’s residents and businesses. This GSP will ensure
long-term viable water supplies while maintaining the unique cultural,
community, and business aspects of the Subbasin. It is the express goal of this
GSP to balance the needs of all water users in the Subbasin.
