Volk was elected to two nonconsecutive terms as mayor of Englewood, New Jersey, during the 1960s. He served his first term from 1960 until 1963. The city of Englewood was ordered to desegregate its public school system during his first term. He was elected to a second, nonconsecutive term in 1965, taking office in January 1965. The 1967 Newark riots, which lasted from July 12-17, 1967, broke out in Newark, New Jersey, which is located south of Englewood. On July 21, days after the end of Newark's violence, unrest broke out in Englewood's 4th Ward, a predominantly African American section of Englewood. African Americans had complained of substandard, slum housing and police neglect in the otherwise affluent city. The Englewood unrest, which lasted for five days. included instances of rock throwing, broken windows and one example of gunfire. Several police officers and residents were injured. At one stage of the troubles, he used a helicopter to direct the police. Volk, who was 17 months into his second term at the time of the unrest, agreed to meet with African American leaders and ministers to discuss their grievances during the Englewood riots. He vowed to demolish slum properties in the 4th Ward and increase career prospects for residents. Volk also condemned the violence in Englewood committed by some rioters. At one point during the unrest, Volk wore his Navy uniform as he walked down Palisade Avenue in the 4th Ward with Englewood police and fire fighters. Volk felt that walking with the police and fire fighters would project stability and the need to negotiate the end to the riots. After the riots he appointed a community relations committee to help defuse racial tensions by integrating classes in five elementary schools. However, his actions and use of the police were questioned by some African American leaders. Arnold Brown, who was serving as the first African American state assemblyman from Bergen County at the time, felt that Volk "elevated the situation" through the heavy use of police in remarks about Volk in 2010. Brown explained that, "We had our differences in the '60s... He was just a conservative looking for the status quo." In the fall of 1967, Volk was defeated in his bid for a third term by his Democratic opponent. Democrats also gained the majority of seats on the Englewood City Council in the election. Volk left office in January 1968. Volk was elected to the New Jersey State Assembly in 1970 representing the 37th Legislative District. He served two terms in the Assembly. Volk retired from the insurance industry in the late 2000s.
