Grant Description
Grants to California local government agencies, special districts, state agencies, schools, institutions of higher education, nonprofit and for-profit organizations, and Tribes for projects and installations that use recycled tire materials. Funding is intended to promote the use of tire-derived aggregate (TDA) to increase the recycling of California-generated waste tires. TDA is produced from shredded tires and is lightweight, free-draining, and a less expensive alternative to conventional lightweight aggregates.

Eligible projects generally fall into one of the following categories. 

  • Category 1: Mechanically Stabilized TDA (retaining walls).
  • Category 2: Low Impact Development (stormwater mitigation including stormwater infiltration galleries).
  • Category 3: Lightweight fill (slope stabilization, embankment fill, landslide repair, and retaining walls).
  • Category 4: Vibration mitigation (under rail lines).
  • Category 5: Landfill application (aggregate replacement projects such as leachate and gas collection systems, drainage layers, leachate injection). 

All projects are subject to the following requirements:

  • Only California-generated waste tires, processed in California, must be used in the TDA portion of the project(s).
  • The project(s) must be located in California.
  • A minimum of 500 tons of TDA must be used in the project(s), with the exception of Low Impact Development projects, which must use a minimum of 200 tons of TDA in the project(s).
  • Plans and specifications must be reviewed by CalRecycle staff and/or its contractor(s) prior to commencement of work. For details, see the Application Guidelines document in Supporting Documents, below. 
  • Each project must incorporate technical assistance/training that will be provided by CalRecycle contractors and/or staff.
  • The real property on which the project will be located must be owned by the applicant (or by a member of an applicant JPA).
  • If the applicant’s ownership of the property on which the project(s) is located does not give it complete and clear access to the project site(s), then prior to incurring any grant-eligible costs, the applicant must obtain any and all access rights (e.g., easements) to the project site(s).

Eligible costs are costs directly related to the TDA portion of the project only and are limited to the following:

  • TDA material used (material cost, tax [if any], and transportation to an initial location [either stockpile or project site]) and does not include any contractor markup. Additional transportation cost from a stockpile to a project site is not eligible for reimbursement.
  • Installation of TDA.
  • Engineering/design work.
  • Geosynthetic material (fabric or geogrids) that is specifically needed for a TDA project

For additional information about eligible costs, see Page 7 of Procedures and Requirements in Supporting Documents, below.

For additional information, see page 4 of the Guidelines, in Supporting Documents, below.

Projects that are currently underway or that have been completed at the same location within the same facility within three years of application are not eligible. Landfill application projects do not include use of shredded waste tires as alternative daily cover or alternative intermediate cover.
