Several homes I looked at had no gutters at all. Wouldn't the erosion from roof runoff potentially contribute to sinkholes & wouldn't the erosion predictably get worse over time?

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 five of the recent ones that I have.

I guess I'd find your map more interesting if it didn't exclude practically everything north of the Savanna rec center, as if we don't exist. But I guess that's a good thing? If we had any sink holes up here would we have made your map? How about the historic section?
