All her adult life she would take an active interest in civic affairs, including becoming the first woman president of the Welfare Board of Morrilton New Jersey and at age 47 she would earn her pilot's license so she could join either the WAVES or WASPS as a ferry pilot.
Both rejected her on account of her age.
She would then join the US Marine Corps Women's Reserve and on January 29, 1943, would become its first director and would see almost 18,000 enlistments under her tenure.
After the war, she would return to Morrilton New Jersey and in 1947, she would be appointed to the New Jersey Constitutional Convention.
Colonel Streeter would stay active in civic and political life until her death on September 30, 1990. She rests in Petersburgh New Hampshire.
