Sea Cliff, New York: Real Estate, Schools and News (http://www.newsdayinteractive.com/long-island-real-estate/profile.php?community=Sea+Cliff - broken link)
The Village of Sea Cliff (incorporated in 1883) is in the northwest part of the Town of Oyster Bay, in the north-central part of Nassau County.
Beginning on the north and moving in a clockwise direction, the Village of Sea Cliff is bordered on the north by the City of Glen Cove; on the east by the Hamlet of Glen Head; on the south by the Hamlet of Glenwood Landing; and, on the west by Hempstead Harbor.
The NEWSDAY article failed to mention that the Village of Sea Cliff is the ONLY village or hamlet in either Nassau County or Suffolk County where the same-named postal zone is coterminous with the community whose name it shares: every place in the Village of Sea Cliff has a "Sea Cliff, NY 11579" mailing address and every place with a "Sea Cliff, NY 11579" mailing address is in the Village of Sea Cliff. No other city, village or hamlet on Long Island can make this statement.
The Village of Sea Cliff incorporated in 1883, which would mean that it will turn 125, not 175 as reported in the NEWSDAY article, next October.
