Better sewer and water systems, quality public housing in Flea Bottom or at least some decent housing codes to prevent fires – oh, and definitely the city needs a public fire brigade. (Seriously, kind of shocked that King’s Landing didn’t burn down any time in the last 15 years) A public hospital and public health department is desperately needed. Another institution of higher learning (maybe focused on engineering so as to avoid competing with the maesters?) would be good.
