The latter half of the 20^th Century and the early years of the 21^st Century were periods of whirlwind activity for the Somers Hamlet. Following the end of World War II, the character of the district changed in many ways as veterans returned home from their service overseas. New York veterans and their families were searching for inexpensive suburban homes and given that Southern Westchester county was already heavily suburbanized, many of these veterans began searching for comparable communities in the once rural landscape of Northern Westchester. Several summer homes in Somers and surrounding towns were converted into year-round residences that could withstand adverse winter weather conditions, and many local farmers ultimately sold their properties to suburban building developers. As a result of these developments, the Town of Somers, operating out of the Elephant Hotel, was forced to revise the zoning code it had promulgated in 1944 (which was a revision of the 1934 code) in 1958, and once this legal roadblock had been cleared, the town largely became a suburb of the New York City Metropolitan Region. The Hamlet, already largely built-out, was not directly affected by this housing boom, but due to the population increase in the town, the Hamlet was slowly, but surely converted into a major business district that catered to these new residents. Today, nearly every barn or former rural building in the Hamlet has been converted into a business of some kind, and during this time, the old Peekskill and Croton Turnpikes also became U.S. Route 202 and New York State Route 100. Route 202, which previously had run right up against the steps of the Elephant Hotel, was, beginning in 1986, moved backwards in order to both protect the integrity of the building and to improve the traffic flow that accompanied the increased use of automobiles in the Hamlet.

At the same time that the Hamlet was experiencing the side-effects of the wider suburban developments going on around it, several changes of great importance occurred within the Hamlet itself. In 1956, the American Circus Memorial Association was founded in the Hamlet with the mission of restoring the Old Bet Statue and establishing a museum dedicated to the American Circus. That organization was a forerunner of the Somers Historical Society, which was formally chartered later that same year. In 1957, it was headquartered at the Elephant Hotel as part of the creation of Somers’s museum dedicated to the history of the circus tradition (the museum is still located on the third floor of the Elephant Hotel). In 1959, a further addition was made to the Elephant Hotel with the construction of a meeting hall/court room for the town government's use in the rear of the building. In 1960, another change occurred in the Hamlet, as the boulder that had served as the town’s WWI monument, which had stood adjacent to the Old Bet Statue for nearly 41 years, was moved to Ivandell Cemetery. During the 1980s, this boulder became part of a larger monument at Ivandell Cemetery dedicated to all Somers veterans, and is now accompanied by an authentic World War I-era howitzer cannon. In 1962, the character of the Hamlet was altered further when Nancy Bailey, the widow of William Bailey Jr. and the last resident of the Second-empire style William Bailey House, donated the land that today is Bailey Park itself to the Town of Somers (the gazebo that currently stands in the center of the park was constructed later). A year later, in 1963, the Somers Library, which had operated out of a former cobbler’s shop in the Hamlet, moved into a house on the corner of Routes 202 and 100. The cobbler’s shop subsequently became the Elephant’s Trunk, a thrift shop run by members and friends of the library for its benefit. The shop would close, however, in 1979, after the old cobbler’s house burned down in a fire. Today, the Somers Library is headquartered in a modern, clean building constructed in 1982 outside of the Hamlet.

In 1970, the Hamlet changed still further with the construction of a New York State police barracks along Route 100, just on the fringes of the Hamlet. Additionally, in 1972, construction began on the now-sprawling subdivision of Heritage Hills on Prospect Hill, just north of the Hamlet, which was the same site where William B. Johnson and his counterparts raced motorcycles during the 1920s. The most important development to occur during the 1970s, though, came in 1974. That year, the Elephant Hotel and the Old Bet Statue were placed on the National Register of Historic Places and have since been protected historical sites. In 1978, the Town of Somers would go a step further, designating the entire Hamlet a Business Historic Preservation District with the goal of “preserving the historic development patterns of the Somers Hamlet.” The measure that established the designation was later revised in 1982 and 1984 to provide greater protections to the buildings in the Hamlet. As the 1980s progressed, the Hamlet was altered even more by corporate growth in the town. In 1985, the Pepsi Corporation built its headquarters in Somers, spurring further population growth and adding new population-based stressors to the Hamlet. In 1988, as the Town of Somers celebrated its bicentennial, the I.B.M Corporation established a headquarters, designed by famed architect I.M. Pei just south of the Hamlet, further contributing to traffic congestion and other issues in the area. By the 1990s, though, the Hamlet had largely settled into its new existence as the governmental and commercial center of the Town of Somers.

In the 21^st Century, three events of major importance have occurred in the Somers Hamlet. The first of these events was born out of tragedy. In 2002, the town dedicated a memorial in Bailey Park honoring those Somers Residents who were killed in the September 11, 2001 terrorist attacks on the United States, and the monument remains in a shaded area of the park to this day. However, in 2004, the Hamlet reached a major milestone when it, in its entirety, was placed on the National Register of Historic Places by the United States Park Service and the U.S. Department of the Interior. Since then, the Hamlet and all the historic buildings located within it have been protected under U.S. Federal Law. And in 2014, the Hamlet’s historical character was further cultivated with the addition of an authentic 19^th Century watering trough to the various monuments and plaques in Baily Park.

Since the 1600s, much has changed in relation to the Somers Hamlet, and the Town of Somers at large. But the historic character of the district has stood the test of time and continues to offer Somers residents both a glimpse into the town’s past and a sense of pride in the rich cultural heritage of their community. As Somers continues to grow and adapt to the changing times, the lessons of the Hamlet’s history will continue to serve residents for decades to come. One clue as to just how much the town and the Hamlet have grown up since the days of Stephanus Van Cortland and Hachaliah Bailey can be found in its population data. As of 2019, the Town of Somers maintained a robust population of around 21,574 people, which continues to grow to this day.
