alt Hacker NewsThe river dumping analogy is so bad it's laughable. Obviously you don't own the entire river when the river merely runs through your property nor do you own the ocean or the watershed, and property values surrounding yours go down by a measurable amount when you dump things in the river. What negative externalities does a parking lot create that an empty lot does not? Minimal noise from people pulling in and out? Extra walking time between lots that are built up? Some pollution from the cars? These are normal externalities from literally any building that might be there as well. You can see how this is a different class than a polluted river, and is literally immeasurable.
With regards to the argument presented in the article, it's arguable that parking lots create value by making places accessible to more people. As such, a parking lot raises the property values and economic output of neighboring properties. I didn't see anything about that covered in the article, nor did I see any actual data. This is why chambers of commerce and the like support parking mandates, because they actually have positive externalities, not negative ones.

The frame of mind that brings such comparisons about is anything but funny in a world where all our votes count the same.

I think it's arguable, but I think it's not the full picture. Let's look at downtown Columbus, Ohio where I live. With the parking lots that exist, there's less housing, which means that people move further away from where they work, creating traffic, creating highway construction costs, insurance, &c. I'm quite sure that creating a parking lot makes the location of my employer (well not mine literally) more valuable, but it does seem like it creates more costs. If those lots were, say, because it's a downtown location a 10-story building with 300 residents those people would be shopping downtown, going to restaurants and bars downtown, spending more time there, &c.
There are cases where a parking lot does create economic value, though I think those are more nuanced and limited. I'm not sure your point nor the one you were responding to, nor mine for that matter, are able to really calculate the economic costs of surface parking lots without taking into account factors like, well where the hell is the thing?

Cherry-picking this comment. I'd add to what I wrote above, but I'd also add that I'm not sure that there is evidence to support this statement and if you take this to its quasi-logical extreme you wind up with your entire neighborhood just being one gigantic skyscraper with a Costco and doctors office inside surrounded by parking lots or something. And then the increased profit flows to Costco's shareholders which is fine, but for your local economy that's kind of bad versus having a variety of stores that can open and close. It's putting your eggs in one basket, so to speak.
