# Belvedere king tides and high water in 2009

> In 2009, NOAA's San Francisco tide gauge recorded water high enough for FloodRoute's model to put at least one Belvedere road at risk on 59 days. The highest was 7.42 ft on Monday, June 22, 2009, 0.35 ft above the tide tables, with 36 roads at risk, including Edgewater Road, Leeward Road and Mallard Road.

**Estimates, not records of actual flooding.** Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions.
