Limited interdistrict water transfers have been achieved and serve as proof of concept. __ AGREE _X_ PARTIALLY DISAGREE __ DISAGREE Response explanation (required for a response other than Agree): The Pajaro Valley Water Management Agency Board (“PV Water”) of Directors is aware of the “Pure Water Soquel Project,” which is presently under construction, and the “Surface Water Pilot Project - Phase 1,” which includes an inter-tie between the City of Santa Cruz and Soquel Creek Water District (“SCWD”). Given that Pure Water Soquel is in the construction phase, and the Surface Water Pilot has occurred, it is clear that some inter-district water transfers have been achieved. PV Water is different than many of the other water districts in Santa Cruz County in that it 1) is a groundwater sustainability agency that does not deliver potable water, and 2) the area within its boundaries includes multiple counties and is composed of portions of Santa Cruz, Monterey, and San Benito counties. Given the relatively large distance from the heart of the Pajaro Valley (Watsonville/Pajaro), water transfers with districts located in the mid-county area would be challenging and costly. Furthermore, there appears to be a need and a use for Santa Cruz’s wastewater within the mid-county area as noted above. PV Water has collaborated with the City of Watsonville to construct and operate the Watsonville Area Water Recycling Facility (“RWF”). The Watsonville Wastewater Treatment Plant collects and treats wastewater from the surrounding communities including Freedom, Salsipuedes Sanitary District, Pajaro, and the City Watsonville. The RWF treats the secondary effluent water to meet Title 22 standards for tertiary treated water. PV Water then distributes this recycled water, along with other sources, to agricultural customers in the coastal area where use of the recycled water reduces reliance on groundwater and helps to reduce seawater intrusion and groundwater overdraft. PV Water developed a connection to the City of Watsonville’s potable water supply and purchases groundwater supplied from inland wells to blend with recycled water and other supplemental sources to offset groundwater pumping in the coastal area. These projects are not that different in concept than the inter-district transfers occurring between the City of Santa Cruz and SCWD, and they’ve been occurring the Pajaro Valley since ~2008. The next project to come online for PV Water will be the College Lake Integrated Resources Management Project (“College Lake Project”). The College Lake Project will produce between 1,800 and 2,300 acre-feet of water per year on average, and a maximum amount of 3,000 acre-feet in a year. PV Water anticipates using every drop that the College Lake Project will produce to augment the supply of delivered water sold to coastal growers to offset groundwater production and stop seawater intrusion.

Agency communications to the public emphasize conservation and sustainability while downplaying agency planning to achieve drought resilience. __ AGREE __ PARTIALLY DISAGREE _X_ DISAGREE Response explanation (required for a response other than Agree): In a groundwater basin such as Pajaro Valley, which depends on groundwater for over 90% of the water demand for both agricultural and urban uses, any action that bolsters groundwater supplies during wet periods increases the resiliency of basin aquifers to withstand increased pumping during times of drought. PV Water’s planning for sustainability is also planning for drought resiliency. Projects and management actions included in the 2014 Basin Management Plan (“BMP”) Update, and more recently in the BMP: Groundwater Sustainability Update 2022 (“GSU22”), such as conservation of water resources and increased recycled water deliveries, should be considered drought resiliency actions even as they are implemented in all years. Data from implementation of these projects and management actions show that they help reduce groundwater extraction during all periods, including times of drought, such that groundwater level and storage declines are less than what they were prior to these management actions being put in place. As a result, drought periods should not negate the benefits from recovery of groundwater levels and storage in wet periods. Therefore, the GSU22 provides resiliency by reducing the annual average shortfall over the long-term to meet the Pajaro Valley’s sustainability goals even with the inevitable occurrence of periodic drought. PV Water has many ongoing programs to help achieve sustainable groundwater resources. A brief update follows. In support of PV Water’s agricultural water conservation program, the Board, in December 2020, voted to increase its water conservation budget to $1.25 million over a 3-year period. In April 2022, the Board voted in favor of increased rebates for the “home and garden” domestic water conservation program. In the past two years the Board approved contracts that extended the delivered water service area approximately a mile further north to Monterey Bay Academy, thus reducing groundwater pumping by hundreds of acre-feet per year when the College Lake and Watsonville Slough System Managed Aquifer Recharge and Recovery (“WSS-MARR”) projects bring additional water supply to the coast. The Board directed staff to evaluate and improve Harkins Slough Recharge Facility recovery wells, located west of San Andreas Road. The WSS-MARR projects will create a new point of diversion for surface water on Struve Slough, one that is more protected from brackish water incursions that occur periodically and negatively impact PV Water’s ability to divert fresh water from Harkins Slough as allowed by an existing Required Response from the Board of Directors, Pajaro Valley WMA Our Water Account Is Overdrawn Due by August 22, 2022 [Return to Table of Contents] 2021–2022 Consolidated Final Report with Responses 155 water-right permit. WSS-MARR also includes a new infiltration basin and recovery wells, which will allow PV Water to divert, recharge, and recover a greater volume of winter rainfall runoff when available; PV Water has submitted a water-right permit for up to 4,000 acre-feet to the State Water Resources Control Board. PV Water is also implementing an innovative and exciting program called “Recharge Net Metering,” which partners with local landowners, the University of California at Santa Cruz, and the Resource Conservation District of Santa Cruz County, to plan and develop infiltration basins that capture rainwater runoff and infiltrate the water into the critically overdrafted aquifers of the Pajaro Valley Groundwater Basin. Outreach and engagement with Pajaro Valley customers, stakeholders, and the general public is a critical aspect of what PV Water does. The work described above, along with information about the state of the basin, including drought conditions, is continually communicated through social media, a quarterly newsletter, press releases, informational ads on television and radio, special community meetings, and at monthly Board and Committee meetings. PV Water does not downplay agency planning to achieve drought resilience, as plan development and implementation are critical to both achieving sustainability and drought resiliency.
