Chapter 10: The Southern Coastlands

The southern coastland of San Francisco includes San Mateo and Santa Cruz counties. Unlike the subtropical environment that the southern coastland has, the bay area has a more similar environment to maybe Oregon or Washington. The areas near the Pacific Ocean are generally characterized by relatively small temperature variations during the year, with cool foggy summers and mild rainy winters. Inland areas, especially those separated from the ocean by hills or mountains, have hotter summers and colder overnight temperatures during the winter. San Jose at the south end of the Bay averages fewer than 15 inches (380 mm) of rain annually. Additionally, strong winds are produced through gaps in the coastal ranges such as the Golden Gate, the Carquinez Strait, and the Altamont Pass, the latter the site of extensive wind farms.

CA DOF provides county-level population projections that suggest that SF senior population will balloon over the next 20 years. Nationally, seniors age 66 to 84 are projected to swell from 10 to 20 percent of the population. Those trends are predicted to be significant, but less severe in SF.
