Over time, natural disasters and technology began to take its toll on visitation to the area and the canal was filled in the 1940s. The West End resort has not been redeveloped, although a plan was completed in 1992. The original lakeshore extended to what is now Robert E. Lee Boulevard. In 1927 the Levee Board completed an ambitious seawall and fill project. The Board built a stepped concrete seawall approximately 3,000 feet out into the lake and filled in the enclosed area with material from the lake bottom.
Children are able to walk to school without crossing a single street.
As residential areas were built old industrial uses declined. Commercial development grew along Harrison Avenue, Pontchartrain Boulevard, and Canal Boulevard south of Florida Avenue. Other notable land use changes include the development of the Delgado Trades School, the construction of the Municipal Yacht Harbor and the parkway area along Lake Pontchartrain shoreline. The District also contains some historically significant sites including West End Park and West End Lighthouse and the seafood restaurants found near the marina. These restaurants, built on pilings, are the few remaining examples of a building type formerly found throughout the lakefront region.
