1) Each area of the city has its own characteristics. Some, like the newer areas of Oak Alley and Savannahs have few trees, looped street ways (think accessibility) and underground utilities. All six operations were / are fairly easy to complete.
2) The Division of New Covington (think St. Tammany Health System to Collins Blvd) is a grid system. Within a few days of the storm, the roads were partially cleared and one could zig-zag around the closed blocks. Within 3 - 4 days of the storm, CLECO had scores of trucks working this area. As the power grid was restored emanating from substations, it would be several days before CLECO would begin working in Old Landing / Cherokee Lane
3) Multi-tasking: I observed that the gridded areas could support multiple operations simultaneously. Electric crews, communication company crews and debris haulers could work in the same area albeit on different blocks. The dead-end areas could only handle one trade at a time. At one point CLECO kept Jahncke Avenue between 8th and 4th Ave for at least seven days, immediately followed by Charter and AT&T.
4) This all leads to some parts of the city getting electricity, internet and full garbage service sooner and being cleared of debris more quickly than other parts.
