Their responsibilities include garbage collection using a Trashmaster, street cleaning and public park up-keeping.
The garbage collection branch of the LSD can be found in a warehouse in the Flatfish Place area of the Fishmarket South storing Trashmasters, while LSD street cleaners and gardeners are commonly found on the pathways and grassy patches in parks and road dividers. Many street sweepers around the city are not randomly spawned, but instead are scripted to sweep the same patch of ground when the player is in the area.
Niko Bellic receives an LSD worker's outfit after completing the mission Taking in the Trash for Ray Boccino. The LSD are also used as a front for the Pegorino Family, as their waste management consultation front.
They are based off of the real life NYC Department of Sanitation, even sharing similar logos.
- LSD refers to the class A drug, lysergic acid diethylamide.
