Ya’ll seem to need a major drainage upgrade. Weathers changing we need to be prepared.
Crap when my road and water/sewer lines were replaced four years ago they specifically stated drainage will have a major upgrade we are planing on handling more water in the future.
BTW I live on a sizable hill.
I live in a small city.
There's a project starts about 100 feet (i.e on the corner) from my lot that goes about 4 blocks, just starting, street sewer upgrade. Will address the flooding at my corner (I'm almost at the corner), plus God knows what.
I spent much of the last 2 weeks working on drainage next to my house. My drainage problem has kept me up nights during major storms for years. Now, maybe it won't, have to see.
One thing that could help is increasing the amount of permeable surface, but that means taking space away from automobiles, and we can't do that in America's densest city with some of the best mass transit in the US.
But there is also only so much you can do with heavy rain. It is possible to rain so hard to temporarily overwhelm drainage systems.
They were getting up to 3 inches/hour it said on the news tonight. That's super heavy. I haven't experienced that kind of rain for a long time, if ever.
Saw a report the other day on Lahaina. They interviewed a woman whose house was destroyed who's thinking about going elsewhere because climate conditions are worsening there. It's expected to get more and more desert like on that part of Maui. It's hot and dry there now. OTOH, (and this shocked me!!!), the rainfall on the east side of the island (Hana, I suppose) is 300 inches/year!
Edit: Just looked it up...
What is average rainfall in Maui?
about 400 inches
Average annual rainfall varies from about
400 inches (10.16m) in the high-elevation rain forest above Hana to 10 inches (25 cm) in Kihei, only about 15 minutes apart. Because temperatures drop about 3.2F (1.3C) every 1,000 feet (305m), the summit of Haleakala is roughly 32F (13C) cooler than the beaches. Jun 7, 2022
