Was your city designed for a world before NWS Doppler radars?

Remember when street drainage systems were mapped using only 24-hour rain gauges instead of NOAA's real-time radar arrays? Cities built their catch basins for stormwater in the era before QPF tools predicted rainfall volume, cell movement, and microclimate pockets within an inch. We used to engineer infrastructure assuming linear rainfall accumulation instead of convective bursts that overload pipes overnight. Should urban design today be retrograding those obsolete assumptions as high-resolution weather modeling evolves faster than concrete? Maybe someone built their hometown by the books before radar mosaics—let them take over a podium for defending 1864's rain gauge stats over AI-predicted stormwater surges.

Bonus question: When your zoning board approved development based on 100-year flood plains calculated pre-PRISM gridded data, were they accidentally future-proofing against the delusional?
