Is there a way not to burn? Looking beyond individual solutions

California is still burning, as I write this. Last week's middle-of-the-week post, inspired by the wildfires in the Western USA, was focused on ways that individual property-owners can mitigate their fire risk.

But individuals are not always able to control their surroundings completely enough to take all those steps. Where are your 30- and 100-foot "zones of defensibility" when you live in an apartment building like the one in the photo above, or a densely-spaced neighborhood like the one in the photo below?

With apologies, I grabbed a screen-capture because I wanted to show the contrast in what had originally been published as an interactive graphic from ABC News. To see the original, please go to the article.  Keep scrolling!

Remember, the residents of this community sought out housing they could afford, in an attractive neighborhood that had been safe for years. Here is a mind-blowing, in-depth report by ABC's Matt Guttman. He talks about the speed with which the fires advanced. He also gives some background on the neighborhood and the people who lived there.

With a lovely climate and access to natural beauty all around, it was a desirable place to live, work, and retire. No one expected a wildfire to come through and make it a deathtrap.

But the wildfire did come, and when it did not everyone got out in time, despite  heroic efforts by first responders. Lots of things went wrong (Murphy's Law strikes again), including with the alert systems.

Community planning is more important than we may think, in all kinds of ways--but disaster preparedness and mitigation is definitely one of them that I hope will get more attention as our environment grows more hazardous in this age of climate change.



Some of the principles I touched on in last week's post can be scaled up to the community: not only the idea of zones of defensibility noted above, but also concepts such as the fire danger of developments on a slope, and community building codes.

Other considerations include ensuring that fire equipment can get to burning buildings, whether permeable paving designed to mitigate runoff can stand up to the weight of fire equipment, and many more. Sometimes even seemingly offbeat solutions can work really well, too. Consider wildfire mitigation via goat-power:



Simply not developing some areas because of their increased risk (see slopes, above), or to use as "fuel breaks" requires community planners with the fortitude to stand up to the determined efforts of short-sighted, quick-money interests. Their offers can seem very attractive . . . until the disaster happens. Cool heads and long-term planning are going to matter more and more.

Many thanks to all!

Is your city flood-proof? More creative approaches needed!

Today's Artdog Images of Interest focus on the flooding of Manhattan that happened during superstorm Sandy in 2012. It's part of this month's ongoing focus on the environment. Let's take a look at what happens when a city is unprepared.

Construction sites didn't fare well either. This is the Ground Zero site in 2012.
Commuter nightmare: still-flooded South Ferry subway station in lower Manhattan, a week after Hurricane Sandy.
Recent thinking among some city planners for coastal cities around the world is that the floods will come. Old-style thinking calls for building higher levees and praying a lot (ask New Orleans how that worked out). 

More creative approaches, however, are calling for flood-conscious building--that is, knowing the floods will com, but being ready for them. An article reposted on Arch Daily from ArchitectureBoston calls it taking a layered or tiered planning approach.

Manhattan flooding predictions from the Union of Concerned Scientists. Will they be better prepared next time?
How can cities proactively plan to minimize flood damage? Avoid building in floodplains (What an idea!). Reclaim "buffer" wetlands to mitigate storm surge. Build so lower levels are flood-ready, and place more vulnerable parts on higher levels. Making some parts of the city "floatable." These are just a few of the more creative and environmentally savvy approaches proactive planners are trying.
