Hurricane Dorian headed out to sea without to much damage here. There was some flooding and the cities opened up some shelters, but only a few folks went to the shelters. Based on experience, they probably live in areas that routinely flood.
There are two main reasons for regular flooding:
- The sea level is rising while the land mass is sinking.
- Lots that were once considered unbuildable are now being developed as waterfront.
Unfortunately, this means that some newly constructed homes will not last as long as their mortgages. One house, in such an area, had a “No Wake” sign on the mailbox, which was only partially in jest.
Mother Nature loans us many things, but we need to remember that they’re only a loan.
Norfolk, Virginia has much of its downtown built on filled in waterways and swamps. The area already tends to flood with nor’easters, and tropical storms, but with rising sea levels, flooding is expected to happen more often. Since there are people and businesses already established in the area, government officials are exploring possibilities such as levees, flood walls, and whatever the latest technology offers to prevent loss of life and property.
I understand. Where I live used to have a moderate risk of flooding, but as more of the area was developed the waterflow reversed. Low-lying wooded areas were clear-cut, raised five feet, and houses built so that instead of absorbing the rainwater, it now flows into my neighborhood. Bummer. Maybe if I replace my lawn with rice it will work better.
Mother Nature only loans us geography. I used to live in Louisiana. Mother Nature wants to move the Mississippi River west into the Atchafalaya basin. The United States Army, Corps of Engineers have been tasked with keeping the Mississippi River where it is. They’ve been mostly successful, except for the occasional world-class disaster like Katrina. History has shown that if weather doesn’t satisfy Mother Nature’s requirements, the occasional earthquake will. The New Madrid Fault in the early 19th century caused the Mississippi to flow backward for several days and reroute itself.
These issues are not unique to Norfolk and Louisiana. I grew up in Toledo, Ohio, which is built on what was the Black Swamp. Part of Downtown Chicago is built on the rubble from the great Chicago Fire, which was tossed onto the shore of Lake Michigan. Enough of Florida is built on drained swamps, or the equivalent, and so much groundwater is extracted that sinkholes routinely swallow cars or even houses.
Mother Nature loaned us these areas. I hope she doesn’t want them all back too soon.
