Achieving Groundwater Access for All: Why Groundwater Sustainability Plans are Failing Many Users

Groundwater Leadership Forum | July 3rd, 2023

California made a serious commitment to bring the most depleted groundwater basins back into balance when it passed the Sustainable Groundwater Management Act (SGMA) in 2014. This commitment is being carried out at the local level through the formation of hundreds of new groundwater agencies, the launch of basin-level planning processes, and the creation of groundwater sustainability plans. This report summarizes the results of a scientific study published in Nature Communications. that analyzed the degree to which these groundwater plans equitably integrate and protect vulnerable groundwater users, and suggests course corrections in the ongoing SGMA process to ensure we are preparing our groundwater basins for a changed climate.

Achieving State Goals for the Sacramento-San Joaquin Delta

Legislative Analyst's Office (LAO) | January 15th, 2015

The Sacramento-San Joaquin Delta (Delta) is a biodiverse ecosystem that covers about 1,150 square miles and supports over 700 species of fish and wildlife. The Delta is an important source of water for the state and is used to convey water from Northern California to Southern California. The Delta faces several significant problems, including: (1) a decline in key native fish species, (2) reductions in the amount of Delta water available for use elsewhere, (3) water pollutants that cause harm to species and increase treatment costs, and (4) levees at significant risk of failure. The state has engaged in numerous efforts to address these problems and achieve its "coequal goals" for the Delta: water supply reliability and ecosystem restoration. There are many opportunities for the Legislature to improve the success of these efforts. We identified several issues for its consideration, including (1) demands for Delta water, (2) uncertain funding sources and slow implementation of some key activities, (3) limits on the effectiveness of governance in the Delta, and (4) challenges to restoring the Delta ecosystem. By addressing some of these issues, the Legislature can improve the likelihood that its goals and objectives for the Delta will be realized.

Achieving the Human Right to Water in California: An Assessment of the State's Community Water Systems

The Human Right to Water Framework and Data Tool (CalHRTW 1.0) provides a consolidated, stand-alone, quantitative assessment of baseline conditions in the quality, accessibility and affordability of California’s drinking water. This assessment can help screen for drinking water challenges and analyze changes over time and complements existing cumulative impacts analyses (e.g., CalEnviroScreen (OEHHA, 2021b)) by providing information at a greater level of detail regarding drinking water.

Adaptation Pathways: San Leandro Operational Landscape Unit

Given the diverse uses and conditions of San Francisco Bay’s 400-mile shoreline, a framework is needed to guide development of adaptation strategies appropriate to local conditions. Operational Landscape Units (OLUs), outlined for the San Francisco Bay in the San Francisco Bay Shoreline Adaptation Atlas (SFEI and SPUR 2019), share common physical characteristics and therefore can benefit from being managed as individual units. OLUs cross traditional jurisdictional boundaries (cities, counties), and instead follow the boundaries of natural processes like tides, waves, and sediment movement. By planning at the OLU scale, it is possible to prioritize adaptation strategies that work synergistically. Coordinated OLU planning can help avoid unintended impacts on neighboring locales and identify synergies to make use of limited resources in a more efficient manner.

Adaptation Planning for the Bay Point Operational Landscape Unit

This document is not a vision or an adaptation plan, but rather is meant to catalyze discussion and offer resources around nature-based opportunities for SLR adaptation along Bay Point’s shoreline. The engagement and leadership of community-based stakeholders is key to the success of any adaptation planning effort, especially around issues as long-term and far-reaching as SLR and associated storm and tidal flooding. Without transparency and intentional community engagement throughout the planning process, opportunities for creative solutions will surely be missed and might lead to new problems or exacerbate existing ones disproportionately felt by low-income communities and communities of color. At the time this memo was written, there was not an active SLR adaptation working group or equivalent effort happening along the Bay Point shoreline. Consequently, the intent of this memo is to offer useful resources and ideas to support meaningful dialogue among stakeholders about shoreline adaptation planning. The Bay Point OLU study area is a mix of open space and developed areas at the mouth of the Sacramento and San Joaquin rivers, where the Delta meets the San Francisco Bay. The Bay Point OLU comprises unincorporated land known as Bay Point, a census-designated place within ContraCosta County, the City of Pittsburg, the spheres of influence of Pittsburg and Concord, and District V of Contra Costa County (Figure 2). Chapter 2 examines how Bay Point’s landscape has changed over time and Chapter 3 summarizes some of the vulnerability studies, habitat goals, and adaptation plans that have been developed for the study area. Chapter 4 offers more in-depth descriptions of the Bay Point OLU along with detailed maps that can be used to kick start SLR adaptation planning with a stakeholder working group along this reach of shoreline. Chapter 5 concludes with conceptual ideas that may be appropriate for different reaches of the shoreline, as a menu of possibilities to be further developed through a stakeholder process. Chapter 6 suggests ideas on next steps needed to move this work forward and offers a list of potential stakeholders as a starting place towards an adaptation working group to identify, evaluate, and prioritize adaptation strategies to manage flood risks along Bay Point’s shoreline.

Adaptive Management and Science for the Delta Ecosystem

Using science to adaptively guide management for the Sacramento-San Joaquin Delta is widely talked about as good public policy.  Almost every agency, stakeholder, and planning process professes support and has its own adaptive management and science efforts.  But highly fragmented adaptive management and science cannot solve such urgent complex problems. California’s 2009 Delta Reform Act recognized that meeting the co-equal goals of a sustainable ecosystem and water supply reliability in the Delta required major changes in governance, planning, and management. Such changes also require major changes in how science is organized and employed in management. Here is a straw proposal for integrating the many parochial science and adaptive management programs for the Delta.
