As much as I hate the parking hassle at ABasin I'd still hate to see them add a parking garage, paved lots, or even expanded parking. They sit in the headwaters of an important river in a tight valley that is famous for its natural beauty. I'd rather they close the resort or raise the price 1000% rather than see them uglify the area with expanded driving and parking options. I overlook alot of my own selfishness in order to ski there but if they have to ruin that valley to make the place work then we should all find other things to do with our time. We're enough of a cancer on the land as it is.
I completely agree with you if Abasin decided to put up an ugly, simple concrete parking structure. But if they are held to a high standard, whether that's by the USFS, the public, or their own goals, I would imagine that they could design a parking structure that would actually be neutral at worst, and hopefully better than what currently exists.
For one, instead of allowing cars to park on the roof, they could have a green roof, which is essentially a roof that is covered in vegetation. They are becoming popular on new buildings here in Boston. Not only are they attractive, they allow plants to grow on a surface that in Abasin's case would otherwise be gravel/sand.
Additionally, they would need to choose attractive facade elements for the side of the garage. Although they aren't common, there are some beautiful, architecturally pleasing parking structures out there.
While this would probably be less physically attractive, another option would be to have the roof of the parking structure coated in solar panels. While perhaps not physically attractive, this would be great for the planet.
The bigger question that Abasin patrons ought to be asking when it comes to parking though is the tradeoff between parking and crowds on the slopes. It sounds like the parking situation at Abasin currently limits the total number of skiers that can be on the mountain at one time. With the recent terrain expansions, I do not hear a whole lot of complaining about lines or crowds (with the exception of early season). Would folks here be willing to accept more available parking for more lines/crowds? Improving access is a double edged sword. As an example, I am very interested in the debates over improving access to Little Cottonwood Canyon (Snowbird, Alta). Many proposed solutions would be ecologically friendly and would allow for improved access...at the cost of making these mountains even more crowded.
