How can we navigate changes in the home insurance market?

By upgrading the roof and vents and clearing the area within 5 feet of the structure, homeowners helped this house survive the 2018 Camp Fire.

A wildfire shockwave recently hit California. Maybe you missed it. While there were no large wildfires threatening homes, and the air wasn't thick with smoke like in the Northeast from the wildfires in Canada, a shockwave did hit.  

State Farm, California's largest home insurance company, issued an emergency declaration. As I write this, I note that my homeowner's policy is with State Farm, and while this may not affect me today, it could affect me when I choose to sell my home or buy a new one.   

State Farm announced they will stop issuing new home insurance policies. Allstate issued a similar policy last year. These actions, in essence, shrink the available pool of insurers in California and are a very troubling sign for all of us. Furthermore, this action may significantly lengthen the time it takes to sell or buy a home in California or may affect our long-term ability to sell in the future and capture the financial values we have in our properties.

The loss of over 43,000 structures to wildfire over the last 10 years has not gone unnoticed by the insurance industry. Increasing fire hazards and skyrocketing costs to rebuild has everyone on notice that business-as-usual is not working.

Hardening the exterior of a structure to wildfire is a key element in property protection. It is best accomplished through a combination of materials, proper installation and long-term maintenance.

California's policymakers and the Insurance Commissioner have their hands full with structuring the insurance market, creating a market that manages risk and attracts a diversified pool of insurance carriers, stabilizing insurance availability and affordability, and supporting the real estate sector of California's economy.

As a member of the state's Risk Modeling Workgroup, I can tell you that many approaches are being debated to address our challenges, including 1) allowing reinsurance calculations to be a part of insurance rates, 2) finding other ways to fund the Fair Plan (California's insurance plan of last resort), and 3) allowing catastrophe models to forecast risk in order to better anticipate future losses. With the passage of Proposition 103 in 1988, rate setting has been driven by past claims experience. Most suggest that future losses are likely to be significantly worse than past losses.

On July 13, the California Insurance Commissioner will hold a public hearing on whether rates should utilize catastrophe models that can account for anticipated climate changes and risk mitigation actions taken by property owners.  Further, the state's Risk Modeling Workgroup will issue a report on this topic later this summer.

Embers, radiant heat and direct flame contact present unique challenges to buildings. Protecting a home from future fire exposure requires an understanding of all three fire exposures and a combination of fuel reduction and home hardening actions.

While these approaches are nuanced and complicated to understand, there are many actions that property owners can take to protect the value of their properties and mitigate risks.

Given this period of insurance instability, the best action property owners can take is to understand and mitigate wildfire risks. Reducing fuels, improving defensible space, and hardening the exterior of their structures to heat, flame and ember exposures will help to entice insurance companies to underwrite your property, enhance the ability to sell the property, and improve the odds of the building surviving future wildfires. By marketing the value of these actions, just like the remodeled kitchen or other property upgrades that attract homebuyers, you can market your asset to future insurance companies and buyers. Proactive actions, like upgrading vents, are a key part of the solution. 

 

Reducing fuels around a structure is a key action both to reduce pathways for fire to travel to the property, but also to create a space where fire crews can work to safely defend a structure.

AB 38 (2019) started this process by mandating that the seller of a property disclose to the future buyer defensible space actions that have occurred for properties in Very High and High Fire Hazard Severity Zones. In 2025, these disclosures need to include home hardening actions based on an established low-cost retrofit list. Over time, these actions are likely going to become key for the negotiation of price and potentially the closure of the sale.

Independent assessment of preventive actions may also be helpful. The Safer From Wildfires program was established in 2023 to help promote insurance discounts for the voluntary adoption of wildfire mitigation actions; in my opinion, it could be used as an insurability assessment as well. Another option is to consider the Insurance Institute for Business and Home Safety's Wildfire Prepared Home designation. Helping your community think through the issues and take collective action to meet a Firewise designation is another approach to consider.

More information about home hardening and defensible space can be found at UC Cooperative Extension's Fire website. And if you need help navigating a recent insurance cancellation, United Policyholders, a consumer rights advocacy organization, has helpful resources.

Wildfire adaptation will not occur overnight, but I believe we have a pathway and clear evidence to demonstrate that these types of specific actions will help all of us live successfully with wildfire in California now and into the future.

Drought focus of Water Resources IMPACT magazine special issue

UC ANR experts address emotional toll of drought

Preparing the American West for prolonged drought is the focus of a double issue of Water Resources IMPACT magazine. The California Water Commission staff are guest editors for this special open-access edition of the magazine, which is published by the American Water Resources Association.   

Faith Kearns, academic coordinator of University of California Agriculture and Natural Resources' California Institute for Water Resources, is among the authors delving into how drought impacts people and the environment and how we can better prepare for the inevitable. 

The first issue, published on Feb. 14, focuses on water scarcity issues confronting California and the ways these issues affect different sectors. 

In “Trauma, Care, and Solidarity: Addressing the Emotional Toll of Chronic Drought,” Kearns highlights the effects of drought on mental health. She points to the spike in suicide hotline calls when wells ran dry in Southeast Asian communities in California's Central Valley.

By listening to Southeast Asian farmers, Ruth Dahlquist-Willard and Michael Yang of UC Cooperative Extension were able to “lighten the load” for them by providing pragmatic support, Kearns writes.

“The scale of some of these highly emotional issues – drought, wildfires, climate change – can make them seem incredibly difficult, if not impossible, to deal with,” Kearns said. “At the same time, they are affecting everyone living in the western U.S. on a daily basis. I wanted to highlight and provide models based on work that people – whether they are researchers, clinical psychologists, or Cooperative Extension advisors – are doing right now to ease the way.”

The authors who contributed to the double issue are a diverse array of Tribal experts, academics, nongovernmental organization thought-leaders, water managers and water policy influencers, each of whom brings their own perspective on the topic of drought. Their expertise and perspectives in climate science, water policy and water management will help inform drought-related decision-making and support policies that better prepare the state to thrive during periods of prolonged water scarcity.

In addition to Kearns, the first issue includes articles contributed by:

  • Samantha Stevenson, University of California, Santa Barbara
  • Jay Lund, University of California, Davis
  • Ron Goode, North Fork Mono Tribe
  • Andy Fecko, Placer County Water Agency
  • Jeff Mount, Public Policy Institute of California, and Ted Grantham, University of California, Berkeley/UC Cooperative Extension
  • Nat Seavy and Karyn Stockdale, National Audubon Society
  • Kjia Rivers, Community Water Center
  • Cannon Michael, Bowles Farming
  • Michelle Reimers, Turlock Irrigation District

The January/February edition of Water Resources IMPACT magazine can be accessed, free of charge, on the American Water Resources Association website at https://www.awra.org under “Publications.”

The second issue, to be published in March, will focus on drought response, considering the options for adaptation. This two-part series complements the Commission's work on strategies to protect communities and fish and wildlife in the event of a long-term drought.

Your water-efficient landscape doesn’t have to be barren

UC climate-ready landscape trials identify low-water yet attractive plants

Good news: roses can be a part of your water-efficient landscape. Lorence Oki, UC Cooperative Extension environmental horticulture specialist in the UC Davis Department of Plant Sciences, identified rose cultivars that remain aesthetically pleasing with little water.  

Oki is the principal investigator of the Climate-Ready Landscape Plants project, which may be the largest irrigation trial in the western U.S., and the UC Plant Landscape Irrigation Trials (UCLPIT), the California component of that project. These projects evaluate landscape plants under varying irrigation levels to determine their optimal performance in regions requiring supplemental summer water.

“There are some assumptions that pretty plants use a lot of water, like roses,” Oki said. “Everyone thinks they need a lot of water, but we've found some that don't, and they still look great. A water-efficient landscape doesn't need to look like a Central Valley oak-grassland in the summer. It can look really attractive.”

In 2021, Oki's team at UC Davis identified Lomandra confertifolia ssp. pallida "Pom Pom" Shorty and Rosa "Sprogreatpink" Brick House® Pink as two of the best low-water plants in the trial. 

An Austin Pretty Limits® Oleander growing in the 3-meter spacing deficit irrigation plot in the 2022 landscape irrigation trial at the South Coast Research and Extension Center.

“The useful tip or information that is shared at the end of each trial is the selection and designation of plants as Blue Ribbon winners. These are the plants that looked good with an overall rating of 4 or higher throughout and were on the low (20%) water treatment,” said Natalie Levy, associate specialist for water resources, who manages the project at the UC ANR South Coast Research and Extension Center.

How plants earn a blue ribbon

Each trial year, the selection of new plants is based on research recommendations and donated submissions from the nursery industry. The landscape plants are trialed in full sun or 50% shade cover.

Irrigation treatments are based on the rate of evaporation and plant transpiration (evapotranspiration) measured through a local California Irrigation Management Information System (CIMIS) weather station that provides a reference evapotranspiration (ETo) rate.

Three levels of irrigation are provided to the plants equal to 20%, 50%, and 80% of ETo. The volume of water applied is the same at each irrigation based on soil characteristics, but the interval between applications varies with weather and the treatment. Using this method, irrigations for the 20% treatment are less frequent than the 80% treatment.

“The 20% treatment during the 2022 trial was irrigated an average of once per month while the 80% treatment was irrigated weekly,” explained Levy.

During the deficit irrigation trial, monthly height and width measurements are taken to determine the plant growth index. Monthly qualitative aesthetic ratings on a scale of 1 to 5 are determined for foliage appearance, flowering abundance, pest tolerance, disease resistance, vigor and overall appearance.

A second round of flowering abundance and overall appearance measurements are also taken to capture more of the blooming period. For example, UCLPIT identified in the 2020 trial at South Coast REC that the "Apricot Drift" rose had a mean overall appearance score of 3.5 out of 5, deeming it “acceptable to very nice” and a low water use plant within the Water Use Classification of Landscape Species or WUCOLS guide.

Project expands options for landscape planting

Nathan Lo, staff research associate, and Natalie Levy take monthly plant growth measurements (length, width and height) of the Center Stage® Red Crapemyrtle.
While attending UC Davis as a master's student, Karrie Reid, retired UCCE environmental horticulture advisor for San Joaquin County, assisted Oki with landscape water conservation research. The landscape plant irrigation assessments were initiated at UC Davis in 2004 and the UCLPIT project, now in its 20th year, originated from her master's thesis project from 2005 to 2007. A CDFA grant supported duplicating these fields at the South Coast REC in 2017.

“(WUCOLS) only has 3,500 plants in it. There are guesses that there are close to 10,000 cultivars in urban landscapes in California, if not more,” said Oki. “WUCOLS also didn't have numerical ratings. Instead, you'll see verbal ratings like ‘low water use' or ‘high water use.'”

The UCLPIT project has not only developed numerical recommendations for irrigation, but it has also added new landscape plants that are compliant with California's Model Water Efficient Landscape Ordinance. In fact, UCLPIT's data is one of the few sources that can be used to supplement WUCOLS.

Geographic diversity of trial sites adds to knowledge base

In addition to UC Davis and South Coast REC in Irvine, the trials have expanded beyond California as the Climate-Ready Landscape Plants project and is in progress at Oregon State University, University of Washington, University of Arizona and Utah State University thanks to a USDA/CDFA grant awarded in 2020.

Lloyd Nackley, associate professor of nursery production and greenhouse management at Oregon State University, is the principal investigator of the trial in the Portland metro area, which is entering its third year.

“People know that there are drought tolerant plants, but there are many. We're trying to highlight lesser known or newer varieties. And even though the trial is three years, most gardeners would hope that their garden lasts longer than that,” said Nackley.

One of the observations that Nackley recalls is of the Hibiscus Purple Pillar plant. Unlike the trial at South Coast, the Purple Pillar did not perform well in Oregon in the spring.

“It wasn't until August that we saw the plant bloom and begin to look like what we saw from South Coast in April,” Nackley said.

Jared Sisneroz, a research associate from UC Davis, uses a LI-COR instrument to measure the stomatal conductance of a leaf on an Oso Easy® Urban Legend® Rose plant.

Ursula Schuch, horticulture professor and principal investigator of the trial taking place at the University of Arizona, was also surprised at the range of performance among different plant types and the effects of irrigation, heat and temperature.

“This research will reassure green industry professionals that they can stretch their water budget to successfully cultivate more plants, watering them according to their needs instead of irrigating every plant according to the highest water-using plants,” said Schuch.

Although research is only conducted in the West, the hope is that there will be trials in other regions of U.S.

Doing so would yield comprehensive information about the plants and their performance in different climates. As extreme weather events persist in the U.S., disease pressure and risks do too. Trials throughout the country would provide location-specific data regarding disease susceptibility.
