Street-level flooding is more likely

Heavy rain from a tropical storm could fill more streets with water this year than residents were used to seeing before Hurricane Katrina, according to new government projections.

The Army Corps of Engineers has drawn up maps showing parts of Gentilly, Lakeview and Uptown that can expect rainwater accumulation this hurricane season even if they did not typically flood in previous tropical storms. Closing the floodgates under construction at the 17th Street, London Avenue and Orleans Avenue canals in advance of a tropical system is what would trigger the extra flooding from rain.
