Elmhurst developed as a fashionable district due to a housing development built by the Cord Meyer Development Company between 1896 and 1910, north of the Port Washington Branch railroad station. Cord Meyer expanded its holdings between 1905 and 1930, including Elmhurst Square, Elmhurst South, Elmhurst Heights, and New Elmhurst. Elmhurst also was the site of the Grand Street LIRR station just west of the current Grand Avenue – Newtown subway station. The Grand Street LIRR station was served by the Main Line and the former Rockaway Beach Branch. In the 1930s, the Independent Subway System's Queens Boulevard line was built through the neighborhood, spurring economic development but also destroying many old buildings.
