The cemetery's grounds continued to change. In 1914 landscape architect George Kessler designed a brick and wrought-iron fence nearly three miles long. It was completed in the early 1920s and surrounded three quarters of the cemetery's south grounds and the southern end of the north grounds along Thirty-Eight Street. A bridge/underpass that became known as the Subway passed beneath Thirty-eighth Street to connect the north and south grounds. Although Crown Hill faced competition from other cemeteries in the area, it continued to expand. More than 100,000 people were buried there by the late 1930s and more than 155,000 by the late 1970s. The cemetery's Community Mausoleum was formally dedicated in 1951. Building five of the Garden Mausoleums, a series of outdoor mausoleums, was completed in 1962. A new administrative building by Bohlen and Burns was dedicated in 1969. By the early 1980s, Crown Hill was valued at nearly $3 million. Its annual sales were estimated at $250,000, with an operating budget of $895,000. The cemetery employed fifteen salaried employees, twenty-one full-time maintenance workers, and twenty-five seasonal workers.
