A recent trip to Hong Kong really highlighted San Francisco's inability to handle a rising population density. As of mid-2014, HK's population was 7.24 million across the Island, Kowloon, and the New Territories [1]. The main Island alone has a population density of 16,390/km^2 with an area of 78.59 km^2 [2]. The city is covered in high rises and there is still a drastic housing crisis [6]. However, public transportation was readily available, on-time, affordable, and clean. I was able to travel across the region, to/from Macau, and to/from Shenzhen using only these services. At no point did I need to call a Lyft/Uber/Didi/taxi. Looking at the 9-county portion of the Bay Area, we have a population density of 425.7/km^2 over 18,040 km^2 [3][4]. I realize it's more difficult to support a larger region with accessible public transit, so let's focus on the 7x7 in the city: 7,170/km^2 over 121.46 km^2 [5][7]. Over 40+ km^2 with under half of the population and we can barely keep MUNI/BART running, residents can't afford rent increases, and employees are commuting hours to reach the city [8]. How is the city so far behind HK with a 2016 GDP $470.5 billion (compared to HK's 2016 GDP of $319.7 billion) [9][10]? These articles that complain about skyscrapers changing the skyline or ruining the historic feel of the city drive me nuts. How else will the city be able to keep up with the growing housing demand? We're on a peninsula - we have a fixed area in which we can build. The construction of SF tower has brought 60-ish floors of new employee space into the city without providing an equivalent number of apartments (yes, there are condos but those are certainly not housing all new employees). As these office high rises are constructed, we need to be pumping investments into public transit (a new 60 floors worth of employees will now be commuting within the city) and high rise apartments. They don't need to be luxury apartments (ie. Jasper) but affordable options that can house more than the standard 3 story house in Pacific Heights.
