I’ve heard Roman concrete can withstand and even be strengthened by salt water.

I’m amazed the entire downtown was elevated. Do you know enough about that subject to have an opinion about elevating the Ferry Building in San Francisco? That has to be done for it to survive.

Yeah. I constantly feel under qualified to write solarpunk fiction. But I do it because it needs to be done.

I’m writing a story about San Francisco, where greedy fucks filled in the parts of the bay to sell more real estate. Now those areas are going to flood. Worse, toxic groundwater will rise there first and make it unlivable.

To buffer the rest of the city against floods and toxins, I will portray wetlands restoration. What I’m not sure about is how wide an area the wetlands has to be.

The solarpunk reason to engage with these sorts of swamp cities is that they contain lots of infrastructure and housing that you would hate to lose. Reusing existing buildings is more efficient than building new stuff from scratch, especially high rises.

Cities would be far safer without cars.
