After the turn of the century, the building of homes and barns continued to boom, and with the advent of World War I, good produce prices brought prosperity. The LDS Church played a prominent role in local "culture" through its amusement hall, which brought drama, band concerts, and athletic events to the community. The first telephone came in 1903 to the Walker brothers' store in lower Syracuse. In 1913 electricity lighted the meetinghouse and amusement hall.

In the fall of 1909 permission was granted by the Davis County School Board to open North Davis High School in Syracuse. It was an extension of the old red-brick school. But in 1925 school buses began hauling students to Davis High School, and the Syracuse school was closed.

School principal Arthur Anderson introduced the first scouting program into the community, and in 1921 Eli Rentmeister organized the famous Syracuse Scout Band, which played at Fourth of July celebrations and at the state fair.
