*"Philadelphia, US Flood Map application does not show current or historic flood level but it shows all the area below set elevation."
Disclaimer: Please note that this elevation flood map on its own is not sufficient for analysis of flood risk since there are many other factors involved. Surface runoff, flow diversion, land type etc. are also responsible for the flood coverage in addition to elevation. But this flood map should help in some extent in the following areas:
The elevation layered on the map is in meters and is from sea level. The elevation is zero for the sea level. Negative elevation means depth below sea level.
Notes:Before using this Flood Map application, please note that for various technical or non technical reasons the application is not guaranteed free of bugs or inaccuracies.
