Why it matters
Evacuation zones, school districts, county (Harris or Chambers, which decides the tax office, the sheriff, the court and the alert system), flood maps, transit, and half the site's searches key on the zip. The hurricane page's zone lookup takes it; the schools page maps it; the moving-here page sorts utilities by it.
