Louisiana's governor declared a state of emergency in New Orleans on Thursday as the city's malfunctioning water-pumping system and the threat of more rain left some neighborhoods at greater risk of flooding. The city scrambled to repair fire-damaged equipment at a power plant and shore up its drainage system less than a week after a flash flood from torrential rain overwhelmed the city's pumping system and inundated many neighborhoods. Jamie Hill, a resident of the Mid-City neighborhood that has flooded twice in the past month, was clearing mud, sand, grass and other debris from the storm drain near her home. [...] after the system failed to keep up with a storm that dropped 9.4 inches (24 centimeters) of rain in three hours, the truth about the state of the water pumps began to emerge. Despite what the public had been led to believe, City Council members were then told that pumping stations in two of the hardest-hit areas went down to half to two-thirds capacity Saturday, news outlets reported. Public Works Director Mark Jernigan submitted his resignation shortly after the council meeting, when he was asked whether his agency had done enough to clean the catch basins that feed the drainage system.
