Discussion and Possible Action Including Consideration of Input from Local Water Districts, Purveyors, and Community Partners Regarding Proposal of Priority Projects by District
(Sponsor: Supervisor McGourty)
End
Recommended Action/Motion:
recommendation
Consider input from local water districts, purveyors, and community partners regarding proposal of priority projects by district; and provide direction to staff as appropriate.
End
Previous Board/Board Committee Actions:
On August 2, 2022 the Board of Supervisors provided support to Supervisor McGourty to bring back a proposal of priority of projects by district for which the newly formed Mendocino County Water Resource Team (MCWRT) could initially focus their efforts on and in pursing grant opportunities.
Summary of Request/Referral:
The following is the initial proposal of priority projects by district for review and discussion with the Public Health, Safety, and Resource Standing Committee (PHSR) along with consideration from local water districts, purveyors, and community partners. Discussion from today will be brought back to the full Board of Supervisors for discussion at future date.
District 1: Consolidation of Russian River Water Agency (URRWA)
This is a Joint Powers Authority (JPA) working for the consolidation of Ukiah Valley’s water. The board includes a single member from Willow County Water, Calpella County Water, Redwood Valley County Water, Millview County Water, and most recently the Ukiah Valley Sanitation District. The planed objective is to connect water service from Ukiah to Redwood Valley to ensure there is a safe, clean, and reliable water system suppling potable water to residents in the service area managed as a unit. Consolidation of small water systems for more reliability and efficiency is a stated goal of State Water Resource Agencies.
Cooperating Agencies: URRWA and City of Ukiah
District 2: Winter Ground Water Recharge in Flood Plain Areas
The concept is to divert Russian River water during high flow periods onto the flood plain adjacent to the river where no damage is likely to happen to permanent structures, allowing water to infiltrate into the water table over a wide area. There are multiple places where this can be done in the Ukiah Valley, but the City owned property of River Park might be a good location to try a pilot project due to the close proximity to the Russian River and multiple high-volume wells in Aquifer 1.
Cooperating Agencies: City of Ukiah and Ukiah Valley Basin Groundwater Sustainability Agency
District 3: Delineating and Mapping the Ground Water Basin of Little Lake, Round and Long Valleys
Creating a better understanding of the water dynamics of storage and extraction in these important groundwater basins will inform the sustainable water yield beneath the communities of Willits, Laytonville, and Covelo. As water use has increased in the past decade for various purposes, drying of domestic wells is a huge concern of many residents. Developing a conceptual model of basin’s hydrology and delineating probable boundaries and yields of the 3 aquifers would be the goal of this study.
Cooperating Agencies: City of Willits, Laytonville Water District, and Round Valley Water District
District 4: Increasing Surface Water Storage for the City of Fort Bragg
Fort Bragg depends on surface diversion from the Noyo River which is an adequate supply in normal years. In dry years, the flow may be greatly reduced, and having a backup surface water supply is essential. Presently, the system can store up to 45- acre feet, which is marginal in dry years. There is a desire to create up to 200-acre feet of storage over time to ensure there is an adequate water supply when drought years occur. In addition to supplying Fort Bragg, this water system provides potable water that is trucked to communities from Fort Bragg to Albion when drought conditions cause dry wells in the coastal area, especially around the town of Mendocino.
Cooperating Agency: City of Fort Bragg
District 5: Modernization of Mendocino City Wastewater Treatment Plant
Designed over 50 years ago, this facility is aging and needs rebuilding and upgrading to provide tertiary treated water that can be used for landscaping. Presently, there is only a 3-day emergency storage facility for untreated wastewater which is inadequate should a breakdown incapacitate the facility. Additionally, the town of Mendocino is very water insecure. Modern tertiary water treatment can be used for landscape irrigation and possible groundwater replenishment during summer months when over 25% of the wells supplying town water go dry.
Cooperating Agency: Mendocino City Community Services District
