Solid Waste Program

San Mateo County residents create large amounts of solid waste -- including garbage or trash, bottles, cans, newspapers, construction materials, debris and lawn and garden trimmings. This solid waste is usually picked up by the garbage collectors and taken to transfer centers, where it is separated into materials that must be disposed of in a landfill.

Transfer Stations and Landfills

Environmental Health's Solid Waste Program staff make sure that business, garbage collection and disposal companies and individual residents follow federal, state and local standards and permitting requirements for proper handling and disposal of solid waste.

Inspectors permit and regulate:

  • One landfill, Hillside located in Colma, has recently closed and is in the process of closure construction which should be finalized some time in 2010.
  • 16 closed landfills in different locations around the county.
  • Regulatory oversight of 41 post closure developments (building construction on top of landfill sites).
  • 5 green waste chipping and grinding operations (not open to the public).

The solid waste facilities and landfill sites are monitored for compliance to state minimum standard for the proper handling and disposal of solid waste to prevent the creation of public health and safety and environmental concerns.

After a landfill has been closed, the landfill sites can be used for open space, parks, or for light or commercial developments.
