Fieldston is a section of the Riverdale section of the Bronx, New York City. It is bounded by Manhattan College Parkway to the south, Henry Hudson Parkway to the west, 250th Street to the north and Broadway to the east.
The area is home to two private schools: the Horace Mann School, and the Ethical Culture Fieldston School. The Riverdale Country School, the third of the three prestigious "Hill Schools" is just outside Fieldston to the north. Manhattan College is located on Manhattan College Parkway, the neighborhood's southern boundary.
Fieldston is one of few areas in New York City to be completely privately owned. The streets and common areas are owned by the Fieldston Property Owners' Association, Inc. which plows the streets, does sewer repair, cares for the trees—of which there are about 1000, and runs a security patrol as well as other municipal functions. Annual dues are paid by the approximately 250 homeowners who make up the Association (who nevertheless have to pay the same real estate taxes as their neighbors) to maintain the area. Once-a-year the streets are closed to non-residents to maintain private ownership. Parking is restricted to residents and their guests.
The neighborhoods of Riverdale and Fieldston are one of the wealthiest in the five boroughs of New York City. It is similar in demographics to Forest Hills Gardens in Queens, which like Fieldston, is privately owned.
