wooden stilts, in the shallows along the edge of Lake Pontchartrain, the largest and longest-lasting of these being at Little Woods. In the early 20th century some residential development of the area began, at first as an extension of Gentilly. Construction of the Industrial Canal began in 1918 and was completed in 1923, creating the principal geographical barrier that would separate eastern New Orleans from the rest of city. Eastern New Orleans' present southern boundary was realized in 1944 with the completion of a re-routing of the Intracoastal Waterway, involving the excavation of a new segment stretching east from the Industrial Canal to the Rigolets, cut through the raw swampland south of the Gentilly Ridge and north of Bayou Bienvenue. From the 1930s to the 1960s, Lincoln Beach, on the shore of Lake Pontchartrain, was the city's amusement park for the African-American community. When Hurricane Betsy was bearing down on the city in 1965, eastern New Orleans was the only section for which an evacuation was called, as there was concern that this section of the city might suffer particularly extreme effects. However other than light flooding near the Morrison Canal, damage from Betsy was much more modest than had been feared. However, some of those who evacuated in advance of Betsy's arrival sought refuge in the Lower 9th Ward, which flooded disastrously. Rapid growth east of the Industrial Canal commenced in the 1960s, during the administration of Mayor Vic Schiro (1961–1970). Many new subdivisions were developed in the 1960s and 1970s, to cater to those who preferred a more suburban lifestyle but were open to remaining within the city limits of New Orleans. Eastern New Orleans grew in a comparatively well-planned and neatly zoned fashion. Some care was taken to avoid placing major thoroughfares along the rights-of-way of unsightly drainage canals, as had frequently occurred in suburban Jefferson Parish. Instead, major roads (e.g., Mayo, Crowder, Bundy, Read, Bullard, etc.) were located equidistant from parallel canals and were outfitted with landscaped medians (neutral grounds in the local vernacular). Numerous subdivisions were developed with large lakes at their centers, providing both an assist to neighborhood drainage and a scenic backdrop for the backyards of homes. From the late 1960s onwards, buried utilities were required, lending to new development in eastern New Orleans a pleasingly uncluttered visual appearance quite distinct from the wire-hung stoplight signals, tangled webs of power lines, and forests
