What up with all that rain and localized flooding in Ivanhoe Village?
That’s a great question! We asked the @thecitybeautiful and got a very detailed and well written response:
“Orlando normally receives 0.1-in/day of rain this time of year. We have received over 6” in the last week. One day we received 2.5-in of rain. (That might not sound like a lot, but it's an INSANE amount of rain).
There isn't a single stormwater system out there that will prevent intermittent, localize flooding from that much rain. The highest intensities we calculated specifically for the area of Ivanhoe Village was over a 10 min period at 4 in/hr and over a one – hour period at 2 in/hr. One storm lasted a little over 5 hrs. with approximately 2.5” of rainfall.
To put it in perspective, we normally design the permanent pool (during wet season) in a wet pond to hold a volume of approximately 2”/week. Again, Orlando’s average daily rainfall should be around 0.1 inch / day. This past weekend from Thursday to Sunday yielded a little over 6” in 3 days specifically in your area. With the storm system receiving this amount of rainfall and intensity, the soils would normally get saturated to the point where there is no soil storage. With little or no soil storage, more overland flow would travel to our designed conveyance systems, which would get overwhelmed for a short period. Hopefully, mother nature would allow it to recover in a couple days.
These types of rain events are being seen all over the City right now. It is definitely abnormal, but it is not indicating a failure of the system… the system was just not designed (and no system exists) to handle the storms we have been getting.”
So there you have it! We have rain in the forecast so be careful as you are driving!
