Wildfires: Managing the Risks

How can we limit the spread of wildfires and save people and property?

Wildfires are already a significant issue, and climate change will only make the issue worse, as I’ve discussed in my two prior posts. Reducing carbon emissions may help keep the issue from growing, but we’d like to cope with the risks we’re already facing. That’s going to require a portfolio of risk management strategies.  We’d like to ramp up all of them.

Land Use Controls.

There are increasing numbers of individuals moving into the wild-land urban interface (WUI).The USDA’s report on the WUI says that 3.8 million people live in that zone in California alone. Nationally, one million homes were added to the WUI just in the last decade from 1990-2000. That simply isn’t sustainable.

Human activities increase the chance of fireside from sparks or burns, and houses are typically highly flammable and help fires spread more quickly. Higher land use controls could limit development in high risk areas.  Easier said than done, nevertheless, given development pressures. In line with a 2013 study, ” land use planning for wildfire has yet to achieve traction in practice, particularly in america. Nevertheless, fire history has been used to assist define land zoning for fire planning in Italy, and bushfire hazard maps are integrated into planning policy in Victoria, Australia.” By 2016, nevertheless, Headwaters Economics was reporting on five Western US cities that were making the most of not less than some land use tools to cut back fire risks, though none appear to have imposed outright bans on development in high-risk areas.

Buyouts could also be a fallback in extreme situations. Constructing codes may help — for example, by requiring fire-resistant roofs on recent houses. Liability rules for fires should be fastidiously considered. Making utilities answerable for fires could cause them to take greater precautions, however the prospect of compensation could also encourage people to live in unsafe areas. Then again, fire insurance costs can send a vital price signal in regards to the risks of WUI property ownership, as some Californians are already starting to experience.

Land Management.

Vegetation removal, each in forests and within the WUI, can reduce the likelihood of fires and slow their spread. The difficulty is that this gets harder on a regular basis. In California, the hearth zone has doubled, now including nearly half of the state, and there are said to be nine million acres where the chance is intensified by dead trees as a result of drought or bark beetles. Obviously, a much greater effort goes to be needed, and care needs to be taken to attenuate the environmental impacts of the vegetation removal. In line with the Headwaters Economics report mentioned earlier, some localities are beginning to push owners and developers toward vegetation removal. Where I live in Oakland, inspectors come around every yr to ascertain out the vegetation in each yard. And, along with the measures discussed below, utilities are also becoming more aggressive about vegetation removal.

Utility Precautions.

Wildfires will be began by downed power lines, a reason for the 2017 California Wine Country fires. Utilities have automatic shut-offs when lines go down, but additionally they have automatic reclosers to restart them. Those reclosers must be shut off during fire season. But experts say the failure to achieve this or provide for human oversight has contributed to major fires in California and elsewhere.  Undergrounding wires or replacing wood poles with steel ones, which some utilities have done in fire prone areas, also help. In line with Utility Dive, San Diego Gas & Electric has been a pacesetter on wildfire prevention. Amongst other things, it maps the tons of of hundreds of trees in high risk fire zones. It has its own network of 172 weather stations delivering data every ten minutes, using the information to run hundreds of thousands of simulations to forecast risks. This effort may provide a model of best practices for other utilities.

Emergency Response.

When all else fails and fires spread, emergency response is crucial to saving lives and houses.  Lots more work must be done on this.

The Sonoma County fire of 2017, which killed forty-four and destroyed almost nine thousand buildings, revealed serious flaws in fire response. Because the San Jose Mercury News reports, the state’s Office of Emergency Services, which investigated the response, was sharply critical of local efforts:

“Officials in Sonoma County were ill-prepared, disorganized and lacked sufficient training when deadly, fast-moving wildfires broke out last October endangering about 100,000 people. . . . [M]ultiple alert systems in Sonoma County, overlapping responsibilities and a failure to map out roles in an emergency appear to have resulted in duplication, inconsistency and a few confusion in messages transmitted to the general public.”

Mainly, it’s hard for evacuation orders to maintain up with rapidly spreading fires. Legislators have called for up-dating of warning systems and changing the system in order that residents should opt out in the event that they don’t want warnings fairly than having to opt in in the event that they do.

Within the 2018 fire season, other problems surfaced. The SF Chronicle reported that within the last week of July alone, requests for 900 engines were unfilled in a breakdown of the mutual-aid system between localities. Although the mutual-aid system is well regarded by experts, there are limits to its capability.  The system needs more funding.

The very fact is that wildfires are a part of the “recent normal.”  We’re going to should up our game to cope with this much higher level of risk. The strategies discussed listed below are the starting points.
