Stormwater management is all around you. #SpotTheSCM

On Thursday of @highlyanne's week @realscientists, she was putting finishing touches on a research proposal to do new, cool science on stormwater managment. She also wanted to get people to realize that stormwater managment is already happening in their neighborhoods, so #SpotTheSCM was born.

  1. #Stormwater is generated when rainfall can't soak in because of pavement, roof, or compacted soil. Runs off to sewer, stream or SCM instead  https://twitter.com/adeelah37675/status/789199794912661504 
  2. Where do you see #stormwater management in your neighborhoods? Can you #spottheSCM today? Tweet at me with your photos & I'll respond.
  3. I started the #SpotTheSCM trend off with this shot of the #SCM next to where I park my car. It had rained over 1.5" overnight, so there was plenty of stormwater to be managed.

  4. Today's ☔️ makes this a perfect day to play #spottheSCM (SCMs are #stormwater control measures). Here's the dry pond outside my building: https://t.co/q3lqXMmab4

  5. Sadly, this SCM is not one of my favorites.
  6. It's definitely not so dry right now, so it is doing its job. Which is good because this #SCM has had a lot of problems #spottheSCM
  7. However the forebays don't seem to be retaining as much water as I'd expect given 1.65" rain. They are dry. pic.twitter.com/fBiauzHUVU
  8. This #SCM has some design & construction flaws that clearly haven't been overcome even though they did repair work this summer #spottheSCM
  9. As a #stormwater hydrologist this makes me a little sad - because it is lost potential to do good. #spottheSCM
  10. Contrast that with pictures of the #SCM near my building in drier times. The architecture SCM is designed for infiltration, this 1 is not https://t.co/2Z2e8mFOA8

  11. @robanhk Both actually. The design of this #SCM is bad and dry ponds in general are not a great option.
  12. But there are beautiful and functional SCMs being built in many places.

  13. But the #SCM at the new @kentstate architecture building down the street is a thing of functional beauty. #spottheSCM https://t.co/Cgewjhc5rS

  14. But let me focus on the good #SCMs, particularly those that promote infiltration, ike this bioretention cell at U of Vermont #spottheSCM pic.twitter.com/68eWiseBfY
  15. Or this green roof @clevemetroparks Watershed Stewardship Center where infiltration and evapotranspiration decrease runoff #spottheSCM pic.twitter.com/hmKhWvQSYT
  16. Green roofs have lots of #cobenefits. Reduce heating and AC costs. Improve air quality. Pollinator habitat. And more... #spottheSCM  https://twitter.com/DeitschFactor/status/789204648271814658 
  17. 3 hours and 3 lines to go in #grantwriting. In the meantime, enjoy a peek at equipment we use to sample #SCM water quality & measure flow. https://t.co/HIKi40CHlc

  18. We're not monitoring the cistern in the background, but the downspout in the front that drains a green roof #spottheSCM
  19. My personal favorite SCM: The Bioretention Cell or Rain Garden.

  20. My personal favorite tool for managing #stormwater is a bioretention cell (a fancy rain garden) to slow down & soak up runoff. #spottheSCM https://t.co/6UgpGMozej

  21. Here's a huge bioretention cell in a parking lot @clevemetroparks, with an overflow that we've never seen needed. #spottheSCM https://t.co/yACuoJxVGa

  22. The bioretention cell here is on private property but maintained by volunteers from @clevemetroparks, who got #SCMs installed w @EPA funds  https://twitter.com/bobirving99/status/789170655371472896 
  23. The bioretention cells pictured here divert #stormwater from a street into the garden & keep it out of storm sewers entirely. #spottheSCM https://t.co/gdAH6WVz6y

  24. Plants use some of the #stormwater and the rest is filtered through an engineered soil before percolating deeper underground #spottheSCM https://t.co/k7McskiMmc

  25. Some bioretention cells do have perforated pipes (underdrains) that bring water to storm sewer, but more slowly than would otherwise happen.
  26. Rain garden plants have to be able to tolerate wet and DRY. Soils engineered for good drainage.  https://twitter.com/LornestoToledo/status/789204554990489600 
  27. After a while I got some other folks to start to play #SpotTheSCM.

  28. .@realscientists Does it count as #spottheSCM if it's outside my own front door? 3 1/2 acres in Pinellas County FL, no watering! pic.twitter.com/xVITGZGtiohttps://t.co/xVITGZGtiopic.twitter.com/xVITGZGtiohttps://t.co/xVITGZGtiopic.twitter.com/xVITGZGtiohttps://t.co/xVITGZGtiopic.twitter.com/xVITGZGtio
  29. Though maybe not everyone's phone is filled with photos of SCMs like mine is.
  30. @realscientists I loved it when I learned what these were, now I see them everywhere!
  31. Once you start to #spottheSCM you will see them everywhere! At gas stations, restaurants, on campus...everywhere.  https://twitter.com/skiddelywoo/status/789202979811274753 
  32. And as I walked across a soggy campus, I spotted a new one for my phone to capture. This one isn't perfect (and maybe isn't even designed as an SCM), but it is kind of a vegetated swale, where runoff from the sidewalks is slowed down by vegetation before it reaches the storm sewer inlet.
  33. Is any stormwater management to be had in flat and ~at sea level South Florida? Yes!

  34. .@DeitschFactor There is still stormwater in south Florida! And some fascinating issues with clear sky flooding. #spottheSCM
  35. After I said there was, he decided to go on an impromptu #SpotTheSCM scavenger hunt. And livestream the process.
  36. May be misunderstanding what constitutes #SCM but I gave it a go. #spottheSCM Not sure if some of these count. @realscientists https://t.co/TnQIDuABiK

  37. These look like an application of permeable pavers that allow #stormwater to inflitrate. Grate in background is for overflow. #spottheSCM  https://twitter.com/DeitschFactor/status/789161285678018560 
  38. It's a little weird that the permeable pavers appear to slope up from road. Maybe they are trying to catch sidewalk #stormwater #spottheSCM  https://twitter.com/DeitschFactor/status/789161285678018560 
  39. That was fun & educational! I think we should institute more interactive-follower hunts for subject matter via #periscope. @realscientists
  40. Someone else asked whether the Netherlands (another flat and near-sea-level place) was doing any stormwater management. The Dutch have a serious historical interest in all forms of drainage.

  41. What about arid areas, like Arizona? Do they have to worry about stormwater? And will the SCMs we've been spotting work there too?

  42. There's a great #stormwater scientist in Arizona working on these issues. You should follow @tmeixner. Green #SCMs work in deserts too.  https://twitter.com/smoroi/status/789203630658203648 
  43. Can street medians be used for stormwater management? Sure!

  44. The better ones are! One concern may be ponding/flooding, but that can be solved with an overflow connection to storm sewer.  https://twitter.com/StarSpngledPuss/status/789171892619911171 
  45. Do we have to worry about falling into rain gardens (or street medians used as them)? Not if we design and build them right.
  46. Some people worry about falling into rain gardens & bioretention cells, but slopes should be gentle enough to not cause problems #spottheSCM  https://twitter.com/pjie2/status/789179751483092992 
  47. But what about maintenance of stormwater management features like bioretention cells? How do we make it happen and make the features keep working?

  48. Maintenance of #SCMs is a good question & an area where we need to improve. We know how but it doesn't always happen. #spottheSCM  https://twitter.com/bobirving99/status/789170655371472896 
  49. @littlerobbergrl @bobirving99 Interesting. I wager the US is even worse at infrastructure maintenance than UK unfortunately.
  50. Important to distinguish between ditches for fast drainage and ditches (or swales) to slow the flow & allow to soak in. #spottheSCM  https://twitter.com/littlerobbergrl/status/789202900601937920 
  51. This tweet and other concerns about mosquitoes kicked off lots of discussion.

  52. Good rain barrels shouldn't breed mosquitos. They are closed at the top & should be emptied ~48 hrs after rainfall. #spottheSCM  https://twitter.com/chumblebiome/status/789204323263741953 
  53. Good ??s about why to empty rain barrels, if doing so wastes water? A: A full rain barrel has no capacity to store next storm. #spottheSCM  https://twitter.com/AliakseiHolik/status/789454868272521216 
  54. If a rain barrel is full it can't do any good. Bigger rain tanks are less likely to fill in each storm. @sendai #spottheSCM
  55. 48 hrs is only a guideline (and works for my area), but key is to pay attn to weather forecasts & empty before next rainfall. #spottheSCM  https://twitter.com/AliakseiHolik/status/789454868272521216 
  56. BUT if you use a rain barrel with an open top where mosquito larvae can grow, please do empty within 48 hours regardless of forecast.  https://twitter.com/AliakseiHolik/status/789454868272521216 
  57. Keep mosquito larvae out of rain barrels (by making sure yours looks like description below) and keep the water until before the next storm!  https://twitter.com/somewhatcivil/status/789463848373936128 
  58. Also common misconception for #stormwater wetlands. Plants attract birds which eat mosquitos. Habitat biodiversity for the win. #spottheSCM  https://twitter.com/chumblebiome/status/789204323263741953 
  59. What eats the most mosquitos? Birds & insects do. So if #SCMs create habitat for them, mosquitos will be naturally controlled  https://twitter.com/Myrmecos/status/789209066446868480 
  60. Bioretention cells and rain gardens shouldn't have standing water for more than 24 hrs. No time for mozzies to grow up. #spottheSCM  https://twitter.com/rattify/status/789212645173829632 
  61. Remembering to empty rain barrels is a pain.
  62. This is a drawback to rain barrels. I've found you have to set yourself a reminder to empty them after storms, whether you need water or not  https://twitter.com/Marmarescobar/status/789208212935368704 
  63. Obstacles to innovative stormwater management:

  64. Home owners assocaitions & municipal regs & lack of funding are major obstacles to using newer & better forms of #stormwater management  https://twitter.com/smoroi/status/789182065237372928 
  65. There is definite inertia in green #SCM adoption by property developers. In US, my sense is most cities are getting on board. #spottheSCM  https://twitter.com/bobirving99/status/789201327066718208 
  66. Getting engineering & construction right are critically important for #SCMs. Problems often occur when corners are cut during construction  https://twitter.com/microcollector/status/789182838843187202 
  67. Incentives for stormwater management by individuals!

  68. Your tweet makes me happy! Gravel driveways are not perfect, but better than paved for sure. Or how about permeable pavement? #spottheSCM  https://twitter.com/somewhatcivil/status/789199416964046848 
  69. This is fantastic to hear! What city do you live in? Many cities have programs where you can get free rain barrels too  https://twitter.com/StarSpngledPuss/status/789199981185949697 
  70. Fantastic! Many cities have #stormwater fees based on impervious surface (look in your water bill). Reduce it with rain barrels & gardens  https://twitter.com/StarSpngledPuss/status/789201298671284225 
  71. I <3 people who want rain gardens. We need more people to take responsibility for #stormwater from their houses & neighborhoods #spottheSCM  https://twitter.com/ycpsych/status/789174731136086016 
  72. And then, the proposal was submitted and @highlyanne was thankful and optimistic.

  73. Proposal submitted! Now just have to cross my fingers for the next 6 months in hopes of doing more cool #stormwater science. #grantwriting
  74. Special shoutout to my partner @Allochthonous for taking care of the family this week while I was immersed in #grantwriting.
  75. This was fun!
  76. Me too! I'd be happy to talk with any city, developer, or journalist interested in better #stormwater management.  https://twitter.com/StuFlemingNZ/status/789202731177091072 
  77. Great part of being here this week is finding others interested in #stormwater. Please follow me back to @highlyanne next week for more!  https://twitter.com/MindiKhan/status/789175818526138368 
  78. .@realscientists is tweeting about stormwater control measures and I'm just sitting at my desk like 😬😁😬😁😬😁 !!YASS rain gardens!!
  79. One of the best things about being @realscientists this week is finding other #stormwater lovers & maybe inspiring some of y'all to care too  https://twitter.com/MindiKhan/status/789175818526138368
