Flood Coverage vs Water Damage – What’s the difference? - AISinsured.com

Flood coverage is also for any type of flooding event including a water main break, swimming pool collapses and floods your home, blocked culverts back up water into your home, drains, etc.

This is near the Villages VA clinic and that Publix.

Pretty far from there, but too west of Lopez country club off calumet Ave. behind the postal station.

Sink hole is the surface collapsing into a void. A void? It can't suddenly happen in one rain. If, it was always a void that fails would it not have shown up with geological tests-RADAR-SONAR?
Oh, and I BELIEVE, it is a permanent record and would reduce the value of your home. When, we bought our home, we were offered an other, ALSO NEW, place when the ssales lady TOLD US, the property had a restored sink hole. If, I recall it was offered at about 10% less.

I understand that, most of us fear sinkholes, and some want to blame someone..

It was this close to the VA. That is close IMHO.

I think that if sinkholes are something really troubling, really frightening to people they shouldn't move to Florida. I don't think we can DO anything to prevent them and I don't see that anyone is to blame.

I think I would much rather live with potential sinkhole issues and hurricane threats than on an island which is the top of a volcano! Hawaii volcano: Lava flows from Kilauea reach edge of power plant

Do any human activities induce sinkholes?

Sure. Sometimes in karst areas [irregular landscapes formed when soluble rocks like limestone dissolve], when you drill a well—looking for water or for mining purposes—as you're pulling water out of the ground, you're lowering the groundwater table. That creates almost a toilet-flushing effect. You're lowering that groundwater level, and the soil that was sitting above just falls out. That's one way.

We also induce sinkholes when we start putting up parking lots and buildings and changing what we call the hydrologic regime. Instead of the water naturally soaking into the ground, it's now running off and being concentrated—being put into the ground at one point. (See "Guatemala Sinkholes Created by Humans, Not Nature.")

From. Why Sinkholes Open Up

4-Health Springs -- impacts of land use in a karst region

Health Springs serves as one of many examples where land-use activities in a karst terrane affect ground-water quality. The region contains coastal springs and karst uplands that are characterized by internal drainage and variable confinement between the surficial aquifer system and the Upper Floridan aquifer (fig. 9). Land use upgradient of the spring was used historically for citrus agriculture but at present includes an extensive golf course, a wastewater treatment facility, and residential and commercial properties. Activities at the wastewater treatment plant have included land application of dried sludge, spray irrigation and ponding of treated effluent. The site is presently planned for a county park; however, elevated nutrient and bacteria concentrations in the spring discharge have delayed this action.

Figure 9. - Sinkholes provide a direct hydrologic link between karst uplands and Health Springs along the coast.
Figure 9. - Sinkholes provide a direct hydrologic link between karst uplands and Health Springs along the coast (from Tihansky, 1999).
In April 1988, several cover-collapse sinkholes developed in an area where effluent from a wastewater treatment plant is sprayed for irrigation. Ponding of the effluent occurred while water levels were at their seasonal low. The maximum seasonal head difference combined with surface loading likely contributed to the formation of several sinkholes which drained the effluent into the ground-water system. Within several days of sinkhole formation, discharge at Health Springs, 2,500 ft downgradient, increased from 2 ft3/sec to 16 ft3/sec (Trommer 1992). A dye-tracer study confirmed the existence of a preferential ground-water flow path linking the upland spray field with the spring (Tihansky and Trommer, 1994). Dye injected into a well located in the sprayfield was detected in the spring water and in a well adjacent to the spring (fig. 10). Ground-water velocity was about 160 ft per day (ft/d) which is 250 times greater than estimates of the regional ground-water velocity (0.65 ft/d) in this area.
Background nitrate concentrations for ground water in Florida generally are less than 0.02 milligrams per liter (mg/L). Water samples collected at Health Springs since 1982 have nitrate concentrations ranging from 2 to more than 10 mg/L. These elevated values reflect the impact of land use in the spring's recharge area.

Yes there are lots of many man made washouts (rotted drainages pipes which have static pressure form water weight in the pond are man made which saturate underground till it reaches cavity and collapse) that natural sinkholes are scapegoated all my opinion of course? And I can have an opinion

[pauld315]

I just got a text from my brother-in-law in Arizona asking if we were all OK. Apparently, NBC National News carried a story on this today and , who could have guessed, made it sound like the whole Villages was being consumed and that some big lake here was emptied.Expect calls to come in from your relatives.

I don't think PVC pipe rots. PVC has been used in Florida since 1975.

You need to get your facts straight. Your map is wrong, sinkhole was on McLawren not McAlpin. That's about 1.5 to 2 miles from the VA Hospital.


Here is a map from 2017 of reported sinkholes in the Villages. Zoom in and look for the yellow dots.

https://www.talkofthevillages.com/fo...-2017-0718-pdf


It shows 9 sinkholes north of 466, 15 sinkholes between 466 and 466A, and 3 sinkholes south of 466A. They happen all over the place and most likely your home is within 1 to 2 miles of where one has happened. Not that scary unless it happens next door.

I agree, and I know washouts don't necessarily equate with flooding. In my opinion, I think the engineers and districts put the affected homeowners behind the eight ball with their insurance companies by calling them washouts, and not sinkholes. Fingers crossed for the home owners.
