Let's cover parkings with PV roofs then we can make use of this energy.

In my home town in Oklahoma, the worst offenders are the churches. Huge parking lots which are only used on Sunday.

Rather than the dream of ubiquitous public transit (which even in compact rail/bus-friendly Japan is often lacking in suburban and rural areas), outside of city centers it seems like a more attainable goal is self-driving cars.

With self-driving cars, you can consolidate parking to single vertical parking structures that service the area, and have businesses and condos in its surroundings build more closely together in aesthetic walkable clusters. As long as the automated valet "fetch" of your car takes only a few minutes people will be happy.

I'm all for reducing parking lots generally, I just can't realistically expect that many others feel like I do.

As a temporary solution, can't they start planting trees in the parking lots? Just give up a single lot for every N lots, and turn it into a garden with a tree that can provide a lot of shade and is low-maintenance.

No thanks. Parking lots are necessary to support driving, which is by a long shot the most convenient and fastest way to travel. This whole war on driving hot take is completely tired because it makes no consideration of the tradeoffs.

This article also makes vague claims of causation, and tries really hard to link the presence of parking lots to the PNW heat wave without any statistical rigor. It also then makes a misleading claim about the likelihood of increasing frequency of heat waves. The World Weather Attribution project’s own paper noted that the recent PNW heat wave would have have been a record breaking event even without climate change, and noted it as a 1 in 1000 years event.

Finally, the article seems to completely ignore the trivial solution of simply putting some shade above a parking lot. It doesn’t have to be trees - it can be reflective tarp held up by poles or a low absorption roof on a parking garage.

Ooooh, related one of my favorite topics.

Part of the reason modern lots are so big and why parking covers so much area is simply because cars are too big! There is zero reason a person needs to own a 7 seat SUV to transport 3 people or five 2x4s twice a year. The proliferation of oversized vehicles continues to exacerbate a significant number of local and global issues and I'm of the belief that we need strong regulation to limit the size of vehicles.

This article was better than I expected, since I misinterpreted the title as if it meant building over car-parks (i.e. putting buildings over them with the parking underneath), which is a good idea!

The amount of surface parking in the US does always astound me when I see photos and videos of US cities... The country I live in isn't especially short on space (Australia) but land is expensive in cities so car parks are usually either pretty small, or they're multi-story or under the building (either ground floor parking with the building above, or underground parking under the building). Just seems like such a waste of space to have these massive surface car-parks. Doing it like it's done in Australia has the advantage of things being a bit closer together, which is better for walking between properties or just walking/cycling in general.

But the interesting thing is that surface parking seems like it used to be a lot more common here from what I remember from my childhood, and development and zoning laws seem to have encouraged what were car parks to be re-developed into much more space efficient use. So it is possible - kind of like The Netherlands and cycling - I wish my city and cities in my country were more like that, but they're better now than Amsterdam was in the 1970s, and slowly going in the right direction. The change is possible.

How about: stop building parking lots altogether and replace the ones we already built with things that are actually useful. Cars are nothing but a huge waste of space.

The new trend in France is car parks covered by solar panels. It provides shades for the cars and deflect the excess heat back to the sky.

I don't understand why cities mandate so much surface parking. It makes the city worse for everyone, including drivers. Why not have the parking under buildings? Sure it's a bit more expensive to build, but saves so much space! And the cars don't sit out in the sun while you shop. Maybe it would be best if there were no parking mandates at all and cities let the market figure out the right amount of parking space.

The town next to me in Indiana has giant oversized parking lots. I swear the Target parking lot is 3 times as large as the Target itself.

There is an upside to heat islands - the winters tend to be a bit more pleasant. I'm not sure what's worse though if you're living in the city - a cold winter or a hot summer; depends upon where you are I suppose.

Paint them white. And roads too.
