The records include subject files, apparently from both the Director and the Deputy Director of the Office. They include materials relating to the application for and administration of grants for environmental concerns; materials relating to City of New Orleans environmental initiatives; and materials relating to other agencies and organizations dealing with environmental matters. Among the areas particularly well represented are matters dealing with Lake Pontchartrain, the Mississippi River, and the Louisiana coastal region; the local Earth Day celebrations; and the City's Brownfields program.
