The housing stock behind San Mateo County's wiring
Housing age is destiny for wiring, and the record the Census keeps for this footprint is specific: a median home built in 1967, 40.6% of the stock from before 1960, 67.5% from before 1980. Inside San Mateo County, that history concentrates the way it does everywhere — oldest near the founding settlements and the early corridors, youngest at the subdivisions still filling in. The electrical consequences are the metro's, felt at county scale: ageing panels where the stock is old, modern loads asking new questions where it is young. Its neighbours - Alameda County, Santa Cruz County and Santa Clara County - hold the same bands in different proportions, which is why their pages read differently from this one.
The climate San Mateo County wiring works under
Position modifies the record: San Mateo County sits 23 miles south of the San Francisco centre, and exposure follows position - the county's open edges take the storm seasons differently from the metro's built-up core, and its low ground and high ground split the freeze and flood patterns between them. The station numbers are the baseline; the county's terrain deals them out. The county's 449 square miles take that record whole; there is no milder version of it inside the county line.
