Plotted where Villages sinkholes have occurred
1 Attachment(s)
I have been a resident of the Villages for only a few years. Using the news releases and postings on this website, I got the elevation chart from the Sumter county website and overlayed (using google maps) the roads of the villages. From that, I put a yellow dot where I have record of past sinkholes; whether big ones or little ones. Using Google earth (which has plotted every road in the Villages) and the elevation they provide, I put the elevation of that area by the yellow dot. Disregarding two areas where sinkholes occurred because of retention pond lining issues, I have 8 others as shown. What I found (though absolutely unscientific) is that of the 8 that I know of, were all below 84 feet in elevation, with the lowest being at 63 ft. There are portions of the Villages where the elevation is much higher... all the way up to 140 feet. No sinkholes have occurred in those areas. So.. I'm thinking that the more elevation / ground you have under you, the lesser the probability of a sinkhole occurring. Anyhow, I'm just sharing for those that may be interested. And BTW, if I am missing any locations from the past, just post it's location and date and I will add to the chart.

Here are some of the post articles used for mapping

Wow, this is impressive. Now I do not recall the details, but there was some talk among the neighbors of a sinkhole near the western end of yearling way, you have the one near the eastern end.
|
Yearling way....
Villagetinker, the one on the eastern end of Yearling way is actually up on the next street on 1906 and 1912 Ussepa Oaks Lane located in the Village of
Pinnelas. This was the sinkhole on the new houses that occurred before they were sold and they had to be fixed by the developer before they could be sold. If you have any documentation on the one on the western edge, just let me know. |

OP, interesting information and as you mentioned----unscientific. When we first retired, we built a home in Royal Highlands which is about 12 miles south of Leesburg. The very first sinkhole was a large one and at the highest elevation in the subdivision. ???? Not having any education or training on this subject matter, I don't know what this means or what your poll of sinkholes in TV means either.
Perhaps someone with "knowledge" of sinkholes can comment. All I know, and have read, a sinkhole can happen just about anywhere in Florida---especially Central Florida. |
Looking around for more info on whether higher elevation is protective against sinkholes here in FL, I read this article from FL Geological Survey, with this excerpt:
"....In general, areas of the state where limestone is close to surface, or areas with deeper limestone but with a conducive configuration of water table elevation, stratigraphy, and aquifer characteristics have increased sinkhole activity....."The entire article is instructive: Facts about sinkholes in Florida - WFLA News Channel 8 |
We looked at a couple of houses in Lake Deaton that had small sinkholes repaired. This included the house with the sinkhole and the adjacent houses. The discount was minimal and since you need to disclose any knowledge of a sinkhole on the property you want to insure to the insurer it didn't seem to be a worthwhile discount, nor worth loosing sleep over. We opted out. BTW, the houses in question were at the bottom of a long hill, about the same elevation as a couple of ponds.
|
They just plugged one in Dunedin on the north side of Hillsborough. They were filling it with concrete last week....one of the houses that haven't been sold yet.....approximately 150 ft West from Viola and Hillsborough.
|
We are visiting soon and looking to buy so I wondered about the sinkhole issue. This is very helpful. Thank you.
|
To me, predicting sinkholes is like predicting 100 year floods.
|
Thanks Frogger.................I enjoyed the information.

I would like an experenced Geologist give us his/her take on if there is any correlation between sinkholes and elevation level of your property. I am skeptical.
|
UGH.......We are only 80 - 90 feet!
|
The OP is sharing his/her analysis given some maps and info......not as an expert, just some info......a grain of salt. I enjoyed the info, but not in the panic mode
|
That was a lot of work OP.. thank you for sharing! I have a question.. what if I take my morning coffee outside right now, walk around my house and find a sink hole.. who should I call? I do know who to call in most situations, this one.. I would have no clue.

I think that the current elevation is not as important as the difference between the elevation of the unimproved land vs. the current elevation. How close did they scrape to the bedrock. The presence of more dirt above the bedrock will more evenly distribute any weight placed on the surface. Look up "angle of repose".
|
There have been sinkholes in clermont. Elevation between 100 and 300.
|
On this map there are some areas where there are few or no sinkholes. Wonder what differs there.

This is fabulous. Thank you for taking the time to try to glean information that isn't readily available. Way cool.

You would think if they can find oil they could find large caverns under property and predict sinkhole may occur. But, IMO that would rule out have the land in Florida :rant-rave: |
Surprisingly, Sumter isn't on this list.

I you had a sinkhole that was not covered by insurance and it was going to cost several hounded thousand dollars to repair what would you do?
A. Fill the with water and stock and it calling it a pond. B. Take out a loan and make the repairs C. Just walk away |
Quote:
Seems that would be catastrophic and that is covered by homeowners insurance. This is an ad, but has some good info; Sinkhole vs. Catastrophic Ground Coverage Collapse |
Don't want to "pirate" this thread (OP I too appreciate your work) wasn't there a group in TV working on a possible "self insured entity" for residents of the Villages to sort of take up the slack where insurance is lacking? Anybody know if there has been any progress on this concept? Sinkhole---always going to happen to somebody else that's what we think.

So how do you figure out the elevation?

I looked at my pdf that I posted and I don't see any by Hillsboro by Neighborly Way. Are you perhaps mistaken? Also, remember that the numbers posted are NOT the depth of the sinkhole but the elevation of the land where the sinkhole occurred.

Added 2 more reported sinkholes

Added the two reported at Fulcrum Place and Zydeco Court in Dunedin and also Sunset Pointe at the Hibiscus Rec Center.

I agree with justjim. What is the purpose of this? Sinkholes are random and do not occur any more here in The Villages than in surrounding areas. Sinkholes make people frightened and so far there is no way to predict or protect people from where they will happen....much the same as hurricanes. |
