The Village of Lake Success maintains its own Public Works Department with a building at the corner of Lakeville Road and the Long Island Expressway that is large enough to house all the necessary equipment.

This department is responsible for maintenance of the Village streets, parks and other property, except the golf course. The Public Works crew plows the snow and sands the ice, and cleans the streets. Cuts the grass and removes refuse on the shoulders, islands and park areas; plants and maintains trees and shrubs; fabricates and installs street and traffic signs and pavement markings; clears and maintains storm drains and sanitary sewers, cleans up leaves, removes fallen branches and storm debris; and does a variety of other maintenance and repair work on the swimming pool and the many village buildings.
