A Resolution to Authorize the Establishment of Tipping Fees for Source-Separated Concrete, Asphalt, Brick, Block, Soil, Rock and Large Tires

Topic Description:

As part of the construction and demolition (C&D) recycling operation, the Corral Farm facility is expected to receive significant quantities of inert materials such as concrete, asphalt, brick and block.  It is proposed that reduced tipping fees be established that encourage source separation of these materials.  These wastes will be processed into stone to be used at the facility and the surplus sold.  Foam-filled block is not recyclable by private firms, but has value as base for landfill roads to reduce stone needs.  An additional benefit of concrete processing is that significant quantities of metal will be recovered for recycling. 

Soil has been accepted without charge for more than a year since the Corral Farm landfill has an inadequate supply to operate.  During this time, local excavating companies have used the facility heavily resulting in the creation of several large dirt stockpiles.  In the past, soil with rock has been rejected since the facility was unable to process the rock; however, rock will be processed along with concrete rubble so that limitation no longer exists.  A modest fee is proposed that will offset soil and rock management expenses. 

Finally, large truck tires have previously not been accepted at Corral Farm.  This requires local businesses to go out of their way to dispose of this waste stream.  It is proposed that large tires be accepted at Corral Farm and charged the proposed fee.

The Corral Farm landfill operation spends approximately $50,000 per year purchasing stone to create and maintain access roads.  With approval of the attached resolution, the facility would spend this money for stone processing rather than purchasing stone.  The excess stone would then be sold for construction projects. 

Staff has visited two concrete collection and processing facilities and spoken to two other facilities.  The proposed fee schedule has been generated while considering local markets and the operating needs at the Corral Farm facility. 

The proposed tipping fees for concrete, asphalt, brick, block, soil, rock and large tires are listed in the table below: 

  A.  Volume-Based Tipping Fees for Source-Separated Inert Materials





Concrete with Re-bar, Brick, Block, Asphalt




Block (Foam-Filled)








Soil Loads with Max 20 % Rocks (2 feet & less)




Soil Loads greater than 20 % Rocks (2 feet & less)









Note: Loads with heavy re-bar (e.g., bridge decking) or Rock (2 feet+) are subject to doubling of fees.

  B.  Tipping Fee for Large Truck Tires:  $75 per tire 


Requested Action of the Board of Supervisors: 

Consider adoption of the attached resolution


Financial Impacts Analysis:

The source-separated materials listed above will result in new revenue streams, reduce operating expenses and be of benefit to the local community.
