This report evaluates the economic dimensions underlying the proposed implementation of the Delta Conveyance Project (DCP) as set forth in documents that the Department of Water Resources (DWR) has presented to date (July 1, 2025). This report is intended to inform economic testimony offered by the CWIN Protestant in its Case in Chief presented in the State Water Resources Control Board Administrative Hearing to address the water right change petitions for the DCP filed by DWR. It may also support testimony that the CWIN Protestant will offer in rebuttal to DWR’s Case in Chief in the future.

Rising Seas and Electricity Infrastructure: Potential Impacts and Adaptation Actions for San Diego Gas & Electric

Part A: Rising sea levels pose a threat to California’s energy infrastructure and the coastal communities that it serves. To better understand this threat, this study analyzed the exposure of San Diego Gas & Electric Company (SDG&E) electricity assets in San Diego County to climate change- driven coastal wave flooding, tidal inundation, and coastal erosion. The study found that the greatest potential direct impacts are damage to four substations in the Mission Bay and San Diego Bay areas. By modeling the potential costs to customers from unserved energy due to service disruptions driven by exposed substations, this study found economic impacts could— under an extreme sea level rise scenario in the late 21st century compounded by a 100 year storm-- range from $1.2 billion to $25 billion, assuming no adaptation actions are taken. Nearby communities could also experience indirect impacts if critical customers served by the substations—such as sewage pumping stations, hospitals, airports, and ports—are affected by outages. For other asset types, potential direct impacts are expected in the form of increased maintenance and repair costs. The research team identified a range of potential adaptation measures to build resilience to potential impacts. The application of flexible adaptation pathways emerged through the study as the best approach to improve implementation of these measures in the face of future uncertainty. Rather than selecting adaptation measures based only on what is known today, flexible adaptation pathways help establish information that that should be tracked, termed signposts, to help navigate uncertainty, set thresholds that trigger adaptation actions, and determine if an adaptation plan is meeting its objectives. Using these pathways, four initial climate adaptation actions were identified for SDG&E: 1) enhance coastal storm prediction and response, 2) identify signposts and thresholds that indicate when the need for an adaptation decision is approaching, 3) conduct consultations with regional stakeholders to identify opportunities to improve community-wide resilience, and 4) improve and fine-tune cost-benefit analysis methods to increase accuracy and confidence in cost-benefit estimates that incorporate climate change.

Safeguarding California: Reducing Climate Risk An update to the 2009 California Climate Adaptation Strategy

California and the world’s climate are changing, posing an escalated threat to health, well-being, nature, and property. Extreme weather, rising sea levels, shifting snowpack, among other impacts will touch every part of peoples’ lives in the next century. Planning key actions now will help us lessen impacts and cope with changes. Many aspects of the environment face historic displacement. In government at every level, we must work together to safeguard our state. And ultimately, each and every one of us needs to take steps to reduce our own impacts and increase our resilience in the future. The Safeguarding California Plan provides policy guidance for state decision makers, and is part of continuing efforts to reduce impacts and prepare for climate risks. This plan, which updates the 2009 California Climate Adaptation Strategy, highlights climate risks in nine sectors in California, discusses progress to date, and makes realistic sector-specific recommendations. California is a leader in the global effort to fight climate change. The state is pursuing a broad, integrated strategy to reduce greenhouse gas emissions and build the foundation for a new clean energy economy. While these efforts will reduce the magnitude and impact of climate change, they will not prevent it from occurring. Given the potential impacts and the long-term nature of effective planning, it is only prudent to begin preparing for these impacts. Actions needed to meet these challenges will not be cheap, but will cost far less than taking no action. Every step that we take today helps save valuable resources in the future. To that end, the plan details 11 current efforts already underway. Right now, more extreme fires, storms, and heat waves are costing lives and property damage. State of the art modeling shows that a single extreme winter storm in California could cost on the order of $725 billion – with total direct property losses of nearly $400 billion and devastating impacts to California’s people, economy and natural resources. The health and fiscal consequences are dire. Climate change poses a threat not just to lives and health, but the financial resources of governments and the insurance industry. More broadly – and likely more costly – are rising seas that threaten our coast, while disappearing snowpack in the Sierra Nevada presents new challenges for our state’s water management. In the near term, we must take practical, affordable steps to maintain our water, power, and transportation infrastructure, and plan for longer term actions as well.
