Typical Closure Threshold: 4–7 inches
The School District of Philadelphia serves 120,000+ students across 216 schools. SDP's decision considers both surface street and school bus route safety. The district has experienced significant budget pressures in recent years affecting fleet maintenance and salt stockpile levels.
Historical School Closure Patterns
Philadelphia's lower-than-expected snowfall total (22 inches/year) makes each storm feel more disruptive than in cities like Boston or Buffalo. SDP schools typically close 3–5 times per winter. The city's hilly terrain in Germantown and Chestnut Hill creates icy road conditions faster than flat areas.
How Philadelphia Makes the Decision
Philadelphia's fleet is smaller relative to its geographic area, which means pre-treatment is prioritized on arterial roads. Side streets in residential neighborhoods may remain icy for hours after main roads are clear, which weighs heavily on the bus route safety calculation.
Philadelphia Snow Day Facts
- Philadelphia averages 22 inches of snowfall per year
