Riverdale Borough Hall is located at 91 Newark-Pompton Turnpike, Riverdale, NJ 07457; phone: 973-835-4060.
Incorporated in 1923, the borough shares its borders with Butler, Kinnelon and Pequannock. Two major highways, Interstate 287 and New Jersey Route 23, intersect within the borough. The construction of the I-287 and Route 23 interchange greatly affected the small borough. While part of its downtown was demolished, the improved access to the New York metropolitan region has attracted new commercial development.
Riverdale as described in 1939 
Riverdale is a trim little village built on a left bend in a hill-rimmed cup of flat land. The New Jersey Historical Commission has allotted to it a share in the State's Revolutionary history, and placed in a vacant lot a marker asserting that "Washington quartered at the Schuyler House July 12, 1777, and visited Colonel Van Cortlandt here March 28, 1782." But Riverdale citizens claim nothing that is not their sure historical due. Miss Mary E. Mandeville, whose grandfather was a Schuyler, knows of no Schuyler House in Riverdale. A possible Van Cortlandt House at which Washington may have stayed is the two-and-a-half-story white frame dwelling with a first story body of gray fieldstone standing across the road from the marker. Charles F. Mickens, who moved into it with his wife in 1886, thinks it may be the place; Mr. Mickens built the frame second-story addition, putting plaster over the old beams—a renovation he has regretted, he says, for 50 years. The Riverdale War Memorial is a life-size statue of a doughboy in a resolute stance, bayonet ready, fist clenched, his helmet tossed beside him on the pedestal; the whole is neatly gilded.
