Our Understanding of Floods is ALL Wrong

Flooding is getting worse, and not just from hurricanes or rising tides, but from increased heavy rainfall. In this episode, we dive into the changing landscape of flood hazards. First, we journey to New York, to visit Hoboken, New Jersey, and Hollis, Queens, two communities facing different flood challenges. Then, we explore First Street's groundbreaking new risk map, pinpointing high-risk areas. Want to take action against flooding in your area? Watch this episode for insights and solutions.
Weathered is a show hosted by weather expert Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

Those of us in the Permaculture and ecological design community have been hollering and beating pots and pans about this for twenty years, it is SO FRUSTRATING that it took this long for this topic to make it into more mainstream conversations but it's so great to see folks finally talking about this issue and working on better urban design. Now let's find a way to put that water back into the use cycle, or at least into soil storage, and not just sending it out into the ocean.

[@GhostOnTheHalfShell]

The parts of the world that need it most desperately are rural areas in poor countries or towns and cities being swallowed by gullies sprouting up everywhere from extreme rain. Integrating green zones that can feed, water, shelter and provide materials for residents also insulates them from the onset of food system collapse (which the world increasing faces risk of). Think Ukraine + Corona but on steroids. Communities that have so far prepared for resilience adapted better to Covid lockdowns. The new republic has a series on the topic.

I work in agriculture in the midwest; our planting seasons have been very inconsistent the last five years. Last year we had very little rain for the entirety of the year; this year, we’ve gotten 6 inches of rain in the last three days. The soil wasn’t ready for it and we’ve had some flooding. We don’t till our land and have a lot of soil conservation practices we follow, but our neighbors have had terrible erosion and it’s filling up the ditches we share, and it’s impossible to get out to some of the fields to get things set up because of how muddy it is. I worry that farmers will be seeing another inconsistent season this year. Recency bias is certainly there but when I ask older folks in the community, they acknowledge that the weather has been “off”, but they get upset if you imply the climate has something to do with it. I’m not versed enough in meteorology to tell either way.

Mitigation efforts like retention ponds and rain gardens work really well. They are also nice additions to park spaces. We know they work, and we should be creating more of them. You can even create rain gardens at home if you have the space. It's better to get the water to seep into the soil than to enter an overburdened sewer system

While this focuses on the USA in particular Canada has also seen huge changes. Living in Halifax, Nova Scotia I have seen huge changes in our weather over the last twenty or more years. The pace of the change in weather has also quickened. Last year I was evacuated when fire burned down 200 homes on the edge of the city. Yet only a few months later we had huge floods washing out roads and flooding many neighborhoods. My concern is the lack of proactive thinking with urban development here in Halifax.

I live in Livingston parish, Louisiana, where we had a "100 year flood" back in 2016. A lot of people had flood insurance, and a lot didn't. The one good thing that came from it was that we realized we can lean on our neighbors in times of need. People who had boats were rescuing people from their roofs, and a ton of local construction workers and other laborers worked for free to help people get their homes back together.

[@reuireuiop0]

Insurance rates are gonna go up, as reinsurance financers are going to recalculate their risk math, if yesteryear 100 year floods now happen every decade.

[@tristanmills4948]

We have a rain garden, for which we got a rebate from the city, to help manage rain events. Other people use water tanks. This not only helps take water away from the under capacity city system, it also directs water away from our foundations, which is one of the biggest water damage risks right here. It's also the nicest part of our garden right now :) Some streets around us also have rain gardens, and some new buildings are putting similar features in, which must help (and the street ones also have the effect of filtering out oil and tyre residue which would otherwise enter the local waterways).

[@KristenRowenPliske]

We weren’t required to have flood insurance because our area wasn’t considered a flood zone. Until Hurricane Harvey drowned Galveston & Dickinson. We had a foot of water in our house & fish in our front yard. Never lost power, oddly enough. Our area is about 20-25 years old, a newer subdivision, and they built several retention ponds around us that worked great until Harvey overwhelmed everything. I’ve lived here for 45years & I’ve been through many hurricanes & tropical storms (TS Allison, H. Alicia, H. Ike etc). I’ve never seen flooding higher than the curb until Harvey.

[@bobloblaw10001]

The detention ponds built for your neighborhood don't really serve your neighborhood, they attempt to protect people downstream. Some street flooding to curb level is generally considered acceptable in the Houston area and acts as temporary water storage.

[@b_uppy]

Much of the problem with flooding in drylands is dry, compacted soil, with the biota withered or deeply challenged. Adding raingardens and bioswales is a cheap way to increase flood resiliency instead of expanding stormdrains. It reduces ground subsidence which harms concrete structures, recharges watertables, regreens, reduces pollution and streetside trash, etc.

[@jaymacpherson8167]

Thank you for covering this topic. As a hydrologist, it has been sad to observe the level of ignorance on what has been occurring for decades. The added benefit of infiltrating runoff is recharge of aquifers…of which many are overdrafted.

My community has been stupid about flood awareness. We have a spillway going through the southern end of town and they decided to build houses on gravel along the spillway. Everyone knows the second we have a flood all those houses will instantly be washed away...

[@cliffpadilla5871]

That's not surprising.

[@Firefenex1996]

A similar thing happened in Houston. They built flood retention areas that serve as parks when it's not raining. People limed the area and built nice houses towards the rear area of the facilities. So when Harvey hit Houston, the city had to decide between holding more water and flooding the nice expensive houses behind the retention area and releasing water on the cheaper houses below the retention area outlet... I think you know which one they chose lol.

[@reuireuiop0]

This even happens in the Netherlands. Southern City of Venlo built their brand new Hospital right out in the Floodplain, narrowing the flood channel of Meuse river by nearly half a mile, which in flood carries over 3500 cubic meters per second (about 12.350 cubic feet). Nearly caused the levees to overflow during the 2021 torrential floods which in Germany took over 180 lives. Hospital had the waters right under its lowest windows.

Portland Oregon USA has been putting in new raincatch parks includng the narrow by the parking space mini raincatches since 2006. Multnomah and Washington Counties have been putting in the mini raincatches since 2005. And Clackamas County is putting the mini raincatches along with bike lanes on suburban streets (they take a lane of traffic out of each side of a wide street to do it) to improve raincatch on the hills and slow down flooding in low areas. They got federal & state funds in 2022 for flood control... and are in the midst of a new 6 year flood control project.

[@Beryllahawk]

Thinking about this makes me remember the city I grew up in - Midland Texas. We all joked about "The River Wadley" - one specific street, Wadley Avenue, consistently flooded every single time there was a thunderstorm. I was too young to understand then WHY the flooding happened, but Midland is smack in the middle of the desert! Annual precip was usually less than 12 inches I think. However, all that dry, dry land becomes hard as rock when it's dry for nine months straight... and that's why flash floods were always such a huge risk, everywhere in the city, even though the storm drains were HUGE. Where I am now there are lots of creeks and green, but the water table's pretty damn high and the soil is almost fifty-fifty clay/sand. The sand drains great, the clay doesn't, and it averages out to something that the city infrastructure can handle. Barely. As things get worse I expect that we'll see more and more flooding, and I hope like hell our city planners are paying attention to what's happening in far away places like NYC. We're nowhere near that built up obviously, this is Mississippi, everyone loves having green around them and there's quite a strong dedication to NOT paving over everything. But that doesn't mean we don't have problem areas, I can think of at LEAST two schools whose parking lots become lakes when it's a bad storm. I've heard about lots of materials science trying to develop permeable pavements and other things that will act more like sponges and allow better control of runoff, but I'm praying that such things become super cheap super quick.

[@DAK4Blizzard]

1:21 - Correct; this is an exponential function called the Clausius-Clapeyron equation. As you can visibly see in the graph, it's not strongly exponential. It accelerates, but it's at a moderate rate. That's because although the temperature variable is within the exponent, it appears both as a numerator (where it multiplies) and denominator (where it adds). So, it partially cancels itself and thus moderates the acceleration. 2:43 - NYC's water system is generally prepared for 3 inches of rain, just not within an hour. I'd rephrase it as the city is not prepared for storms that bring several inches of rain, or bring rainfall rates exceeding an inch or two per hour. 4:27 - The floodplains align "pretty much identically" with the green areas but not the blue areas. What are the green areas? 4:47 - The map accounts for flooding from rainstorms. It doesn't account for flooding from today's heaviest rainstorms. 5:07 - Ida could've been shown as a letter L for a low pressure system, rather than as a hurricane, when it got north of Mississippi. It was below tropical storm level at that point, and it transformed into a mid latitude storm starting in Kentucky. (Even when it restrengthened a bit over NJ and NY, it was still post-tropical. Once a tropical storm goes post-tropical, it stays post-tropical.)

[@fiberpoet6250]

In my hometown, Perry, Georgia (US) We had a huge flood during a stalled tropical system in 1993 and it rained heavy for 3 days. And every dam in the area busted and luckily our little town is on a hill but the surrounding areas were really affected. We were stranded for weeks as all the roads outta town were washed out. After that, our county hired engineers and planners and built a state of the art dam that’s like nothing I’ve ever seen. Instead of a wall.. it’s a row of big cement horizonal pyramids. And it’s never had issues again. Also they got the county to put retention ponds at the end of every parking lot, and we haven’t had flooding since

[@reuireuiop0]

All works well as long as flood installments are kept free and maintenance. But if nothing serious happens over 15 years local boards often decide they have better uses for the money, they can use those nice greens for expensive housing projects and such. Until the next 100 year event, which in climate change, could well be here within 25 years. But then, it will be the next elected official's responsibility

[@peterston4039]

Living south of Atlanta, yes the “weather” has changed. We do get rainfall usually, but the most recent rain falls have been much heavier and we have seen flooding in areas we did into see it before. Also seems that some of the rain event lasts longer and then water over time just accumulates and backs up. We see it in our back yard now over the last couple years, it turns into a lake which is new to us. And local rivers have now reached the bottom of the bridge a couple times recently. While high water sometimes would happen, reaching the under deck is new.

Honestly, here in my working class city in Massachusetts, we keep building and building in green spaces. A sprawling industrial park with lots of forest that was built on a swamp back in the 1940's is expanding and those forested area are now buildings and parking lots, so I am concerned. The ground water levels are frequently just inches below concrete slab foundations. I live not far from there, only 100 meters from the river, but I have mitigated my risk. unlike my neighbors I kept all my trees, and I divert my roof runoff to a small artificial pond, wish a designed overflow with indigenous wetland plants. My next door neighbors cut down their back yard trees so his children would have a backyard to play in, regardless of my warnings to them. They had standing water in the spring for a few days each spring, before they cut the trees. Now it's a about a month of standing water...

Japan has also created underground reservoirs in large cities, but last year the route of rain changed. This is clear from checking the amount of water stored in dams across the country, and I think it is the effect of the meandering jet stream. (I understand that the rainfall was higher than normal, but many dams experienced drought) Therefore, countermeasures have been completed in cities that have suffered damage from heavy rains in the past, but because the route of rain has changed, I think that damage will increase in areas that have not suffered from heavy rain damage in the past. We must promote more fundamental energy conservation measures.

[@eksbocks9438]

One can pump dry water logged areas as much as they want, they remain the lowest lying areas around. As soon as the 100 year event hits, they become wet land again, whether houses been built or not.

My city of Dover, NH unsuccessfully attempted to pass what many ignorantly referred to as a "rain tax" as a way to generate and dedicate funds to restructuring our infrastructure to handle large volumes of water (much of NH is touchy about the idea of taxes). Our city sits only 49 feet (just shy of 15 metres) above sea level and has one of New Hampshire's major tributaries to the tidal Piscataqua River, and we have been seeing some significant flooding begin to become a routine issue (in the past two years I have witnessed the Cocheco River out of it's banks five times, and in the past four years that I have been living at my condo community which sits just a few feet higher, the parking lot has flooded four times, three of which resulted in the loss of personal property, mostly vehicles. Being in a tidal area, we get a double whammy from the tides and flooding.

[@davestagner]

While watching this, I keep thinking of the ongoing demand for greater housing density in urban centers. Here in Minneapolis, we’re building a lot of new apartments/condos on old, often abandoned industrial land. But perhaps some of that land should be used for green space and water retention instead. And south Minneapolis isn’t even a flood zone for the most part! I can imagine this same argument in a place like Houston, with much worse outcomes.

[@Firefenex1996]

Part of the reason why portland looks great is because we have 13 flood control dams in the upper Willamette basin. Portland, and the people of the Willamette Valley in general, realized back in the 50s that life near the river was always going to plagued with large floods unless they could stop it. It's had some bad environmental impacts for animals but no matter how many people sue the dams, they will never be removed as long as potential flooding could cause damage to hillman life and the economy.

[@MikeyfromBOS]

@Firefenex1996 I watched a couple of documentary films about this, the Vanport history especially was a great example of what can go wrong.

Sounds like my country, where Ex pat workers (foreigner with high, specialized education) get a 30% tax cut, which ends up in pushing up house prices. Plus, house buyers get to the deduct their mortgage rent from tax payments, also keeping house prices high. Govt solution is, as you say, build build build. My country however is the Netherlands, mist of the housing in below sea level areas, which need increasing protection as sea level rise, which also means river dikes have to be reinforced, as river levels follow sea level. For every foot higher, the costs of reinforcements double . .

As you push or kick the problem down the road it only seems to gather momentum or steam and come back even harder

[@prattacaster]

Yeah, but the public will bitch and moan if the problem is address years in advance.

Terrific stuff! I'm glad there are some communities thinking outside of the box to mitigate the effects of climate change as we attempt to affect the root causes.

Our Sarasota county in Florida raise some our roads to 5ft high hurricane in 2022 it flooded the main road connected to i=75 highway so county handover the old two lane road to make it into 4lane road. And building a emergency hurricane side route.

That risk map? I can tell you why there's a statistical difference in risk between two counties - parishes here in Louisiana - that are immediately adjacent to each other. In Caddo Parish, which is in the extreme northwest corner of the state bordering with Texas and Arkansas, there's comparatively little residential development alongside the Red River or its tributaries (like Twelve Mile Bayou). We still have flooding problems, and yes, they're more frequent in communities of color. That's still a social and economic problem that needs to be better addressed. But, on the other side of the river in Bossier Parish - the darker blue one right next to Caddo - you have entire subdivisions built alongside Red Chute Bayou. And the builders KNEW it was prone to flooding! I know because I worked briefly in home construction and got out of it. They didn't like it when you brought up flooding events from the late 90's and 2001. And whaddayou know, it flooded again. And those claims show up in the new map. Don't trust contractors to give you an honest risk assessment. As long as they get their money they'll leave you to face the consequences. If we want that to change we have to demand regulation. No industry likes regulations but they still need them.

Thumbs up from being positive and solution driven here. Not an easy thing to be in current atmosphere around climate change.

[@Erik-ri3gz]

How are we doing? I live in Louisville, so apparently let we aren’t doing well. A lot of the “standard” flooding in Louisville is around creeks and the Ohio river waterfront areas, and a lot of those places are in parks and the newly implemented riverfront green space. Water is an issue, but local leaders seem to be doing a pretty good job based on what I’ve seen in the last 14 years. No complaints from me.

[@josesantos2603]

In Brazil, whole cities are now submerged in water in a area as large as England. Porto Alegre, a big city was completely submerged and this is happening in many places close to the ocean.

[@mariafranceschini7662]

Think about it... We, as modern humans, now have the technology to not only communicate and compare with the entire world that things are changing, but to see it happening on a tiny, recorded, human timescale of a couple hundred years means it can't be denied and we need to keep changing (like the weather) to survive.

[@hhwippedcream]

Drought also increases the amount of dead wood and debris our watersheds, especially when it isn't flushed through normal flows. This decreases the effectiveness of 100 yr flow designed/leveed channels with regards to handling "normal conditions" as locally increased roughness leads to concentrated erosion.

The severity of climate change is getting worsen years after years, the world pays higher prices for climate disasters. The awareness of people to take immediate action by mitigation of climate change is a solution to save our planet.

[@Ingcivilcarlos]

Must be noted that storm water systems are designed based on a statistic model from historical weather records, we were missing information to begin with so the systems could have been "somewhat off" from the beginning. Weather is not uniform, we go over periods of macro change as well.

[@mascadadelpantion8018]

We definitely need some rain here in arizona

[@swannman169]

Seems like a win-win, we save fresh water and reduce the likely hood of flooding.

[@sarahcoleman3125]

Just last summer, my city suffered an unheard of rainfall. So much came down so fast that our sewer systems couldn't keep up. My 10-minute drive home took almost an hour, and it had me trying to circumvent several massive "puddles" that I was afraid might stall my car. Unfortunately, these small lakes were at pretty much every intersection and small valley in the road. Our area (se Wisconsin) has a lot of small hills.

[@nonamenojane]

I live in Louisville KY. The rainstorms can be pretty crazy and our local and state governments are doing 0 things to help with climate-related infrastructure improvements or community resilience.

[@DreamerByDay95]

I live in the Hampton roads area of Virginia it floods every time it rains no matter if it’s a short or long storm. I’ve lived here since 2013 and it’s gets worst every year smh

[@theX24968Z]

in drier places, would this mean that more basins and dams would need to be built?

[@eaglescout1984]

I live in an area where floods aren't much a big threat. The ground has a natural slope to allow water to quickly run off. But, that doesn't stop urban flooding. And so far, my hometown has done little to address the fact there are creeks and streams buried beneath the city and homes located at the bottom of hills are going to be flooded if precipitation overwhelms the storm storm system

That poor mother and son. What the hell you shouldn't have to die in your own apartment like that.

[@leelindsay5618]

With all the tillage and throwing away carbon - grass clippings and branches instead of mulching them on site, the soil structure has collapsed and carbon is missing in the soil. Soil life isn't getting taken care of to make those soil agrigates that absorb water. Using a 16 oz bottle of water and a 6 inch metal or pvc ring, you can test to see how long it takes your soil to absorb 1 inch of water, and then 2 inches, and more. If it takes more than an hour to absorb, then the soil is around half a percent of organic matter. Adding carbon or raised Huglekulture beds help to increase soil absorption of water.

Great video but I didn't expect to hear my city in the video. Louisville

[@anniehills3580]

Can we figure a way to capture some of the water in underground containers for use later?

[@reuireuiop0]

Rain water fresh from the roof, yes. Surplus water from ditches, fine for gardens and irrigtation. Flood waters are dirty and often polluted, so, useless and better gotten rid of _quick_

[@DunnickFayuro]

I would love to see more green / terrace roofs as part of the solution

2021 was a summer filled with rain. And my area had zero floods while the Detroit downtown area gets flooded all the time. The city government are totally irresponsible because all their flood mitigation systems were not working. The pumps don’t work, the pipes clogged. Never live in those area.
