The Recovery School District in New Orleans is pursuing an ambitious list of kitchen and restroom repairs this summer. It plans to use 11 kitchens--10 at schools, an 11th at an old state mental health facility--to produce hot lunches for more than 30 schools run or supervised by the state district. The kitchen and restroom program, one facet of a broad rebuilding program, is costing nearly $6 million and should be complete by the Sept. 4 start of class.
