He served in the Senate from 1974 to 1984, representing the 24th Legislative District until 1982, and then served one term representing the 26th Legislative District. Vreeland also served a term on the Morris County, New Jersey Board of chosen freeholders from 1970 until his resignation in 1972. Vreeland"s first political position was Mayor of Montville, New Jersey in the early 1960s, during a period when the area was facing extensive population growth and land speculation with the forthcoming development of Interstate 80 and Interstate 287 that would bring more development to the area.
Though Vreeland stated that he had no plans to sell his 60-acre (240,000 m2) vegetable farm, he was a moderate on the issue of imposing zoning changes desired by many residents to require new homes to be built on properties of at least 1-acre (4,000 m2), in place of the half-acre zoning then currently in place.
State Senate run
Vreeland expanded his mandate in the 1977 general election, defeating Democratic nominee Norma K. Herzfeld by 66.8%-33.2%. In redistricting following the 1980 United States Census, Vreeland was relocated to the 26th Legislative District and in the 1981 election defeated Democrat Benjamin Steltzer by his widest margin, taking 70.1% of the vote to 29.9% for the challenger.
Vreeland argued that the cut "wouldn"t hurt too much", though the effort was defeated. In 1977 rankings published by the Americans for Democratic Action, Vreeland and fellow Republican Frank Davenport received the lowest rankings in the state, receiving a rating of 8% based on a series of 20 votes considered by the legislature.
Teaneck, New Jersey Democrat Matthew Feldman was the only legislator to receive a 100% rating.
Defeat
In what the Philadelphia Daily News described as a "stunning upset", Assemblymember Leanna Brown defeated Vreeland in the June 1983 Republican primary.
