This also means there is a 1/10 chance over 10 years, or a 1/3 chance over the life of a 30 yr mortgage.

Ask anyone on the historic side.
You couldn't cross the golf cart bridge for a week and the power was about that long.
You obviously did not watch the video. There was no code or standards when the historic section was built. Nobody really knows what the system on the other side of 441 was designed to handle. That being said, if your home did not flood the system worked.

During Irma the water level behind our house was high. We got 16”
and it was scary how high it rose.
During Ian they had begun lowering the water level and we didn’t get
as much rain.

We were very lucky in The Villages.

I watched a video of a presentation about the storm water management system. There were improvements made to the storm management system south of 466. The system south of 466 out performed what was expected of it.

There is infrastructure on the Historic side for water management but it is not as good as what was engineered south of 466.

This was a 1/1,000 year event for those areas.
The storm water management system is designed to put the excess water in the golf courses and the streets and tunnels. The goal is to keep the water out of the homes. Irma was a great test to the system (south of 466) and it out performed what was designed. The engineers were delighted with the results.

Not sure about the rest of the Villages, but my neighbor's rain gage only showed about 3.5 inches from Ian down in Fenney, so not sure if that was really a test of the system. I know early on Ian was predicted to move right over us, but it went south/east.

That said, I've read great things about the flood management system here, and based on comments from longer term residents, it seems to work fairly well.

Yup. They got smarter as they started to build further south.

It sounds like are on a retention pond.

If so, how far is the water from your house regularly and how close did the water get to your house during Irma? Do you think another inch would have flooded your house?

If you are not on a pond, how much water was in your backyard and how close did the water get to your house?

There was a post a while back maybe in Deluna where pumps have been running since July.
The narrative of 100 year weather events are now creating a narrative of 500 year events, there are some serious issues to consider with climate events..
Just to clarify, hurricanes and tornadoes are weather events, NOT climate events. Big difference.

Understood and I agree we have probably the best storm water Management system in the world. But at some point with enough rain the system can be overwhelmed.

Based on the information provided, the rain that occurred east of us, now causing record flooding in the St Johns river basin, may have been enough for that to happen in some areas of The Villages.

We had a lot of rain this summer. The lakes were there highest I've seen in there years before this event also. They dropped the levels abut a foot the data before Ira.

True, but they made massive improvements over the past 30+ years...

Appears that you received a lot of "professional" answers on your question. Just wondering how many from engineers that knew or knows the original design parameters and design for various areas of Villages. Same for up grades. My bet not one. Opinions aren't facts and just because you read it on the internet doesn't make it correct. Verify your sources.
