A permit the city can pull
Because the permit is revocable, a street drop can turn into an early pickup with little notice. Keep the customer's contact on the job and give them a way to reach you. In DumpTracker the customer's project link shows the status and drop window, and they can ask for a swap or pickup from it.
Driveways and private lots
Local dumpster vendors say a can on private property needs no city permit. We found no official text either way. When the can goes on a driveway, mark the footprint and the door side on the satellite map. Write the gate code or the HOA rule in the access notes so the driver has it at the curb.
Three C&D landfills south and east
The Colorado Springs Landfill on Blaney Road, Midway Landfill near Fountain, and Fountain Landfill all list C&D. Drivers can record which one they used on the dump ticket, with net tons and a photo.
