A number of East Hampton residents have noticed increased flooding! It’s apparently due to a rise in the ground water level.

Please send us your pictures and we will post them here!

Chronic flooding threatens to sink the value of Hamptons homes
Hamptons homes are very likely to lose value given that they’ll face chronic flooding as climate changes and sea levels rise over the coming years, according to Bloomberg. Behind only Central California, the area has the second highest level of its property tax revenue at risk among U.S. municipalities with a high likelihood of chronic flooding in the next 12 years, the outlet reported. Climate change is expected to bring constant floods that would tank property values, erode infrastructure and sink tax revenue, all of which will make it harder to fund projects to battle the rising seas.

If you are thinking of buying a house in the Hamptons, take a look at this risk chart! Within 60 years you might be 100% sure to suffer severe flooding!

This is a really cool site where you can check the risks of your own home being flooded or under water for the rest of the century. For example I checked my neighborhood (Lionhead and Hog’s creek). By the time there is a 10 foot increase in sea levels my house will be water front property and most likely have a flooded basement. The marina (depicted above) will be under water much sooner. It is located by the inlet to Hog’s creek. There are 2 fresh water ponds (see below in green). They will fuse with the salt water ocean after a 4-5 foot rise in sea levels.

1 foot, marina flooding
2 feet, marina flooding
3 feet
4 feet
5 feet, properties around the ponds will be flooded
6 feet, parts of Runnymeade Drive underwater
7 feet
8 feet, neighbor’s house under water
9 feet
10 feet, our basement probably flooded

Warmer Air, Heavier Rain, More Flooding

David Leonhardt writes in the NY Times about flooding in Grafton, Ill., a small town along the Mississippi River. Because of a bridge closure, the only other way for the vil­lage’s 1,000-plus res­i­dents is to the north via tens of miles of wind­ing, poorly paved coun­try roads that are barely wide enough to al­low a ve­hi­cle go­ing in each di­rec­tion,” The Wall Street Journal’s Erin Ailworth wrote recently. “A 20-minute drive to a gro­cery store now takes a few hours…”

It rained “heavily” all day long in East Hampton NY, on Thursday June 13th. One inch of rainfall according to https://www.localconditions.com/weather-east-hampton-new-york/11937/past.php The winds were out of the NE at about 10-20 mph. Nothing unusual, right?

I decided to take a drive down Gerard Drive. It is arguably one of the most sensitive areas to flooding and East Hampton Town has just completed an expensive fortification of the road to prevent ‘noreaster’ storms from crashing over the road in to Accabonac bay.

The road was passable with large puddles. About 50% of the private drive-ways were flooded.

Then I visited the cross section of Springs Fireplace Rd. and Gardiners Avenue, just by Springs Auto (Edgar’s place). This place usually gets flooded with every storm, at least in recent memory. No surprise:

This kind of flooding was rare 30-40 years ago when I first moved to East Hampton. Perhaps only with a hurricane? Now it seems more common.

To test this I tabulated historic data going back to 2000: a) total precipitation in inches for 6 months (January to June), b) average temperatures measured daily for the same 6 months (January to June). The linear trendlines computed by Excel over the 20 year period, show a slight increase of about 1 degree in average temperature and an increase of about 1 inch of rain per 6 months. Online source of data.

Inches of rain for 6 month period (blue) and average temperature for same 6 month period (red). Measurements are from Westerly State Airport, Rhode Island, about 15 miles north of Montauk.

Warmer air carries more humidity and this leads to heavier rainfall and flooding. It is happening locally and it is a clear and present danger.

Clean energy is one major way we can fight this trend.
