Questions and Answers: Tire-Derived Aggregate (TDA) Grant Program (FY 2015-16)

Questions about the Tire-Derived Aggregate (TDA) grant application were accepted in writing only, no later than January 21, 2016. Similar or related questions were grouped together or reworded for clarity and responded to as one question.

The question and answer period is now closed for this grant cycle. All questions and answers are posted on this site.


  1. How is this grant solicitation different from last year?

    Changes to the project categories. A new Low Impact Development category was added. Additionally, the existing Retaining Wall Backfill category was moved as an eligible project under the Lightweight Fill category.

    Changes to the limit on eligible reimbursement for engineering/design costs. Previously, engineering/design cost was limited to 13 percent of the combined total cost of material, installation, and testing, regardless to the project category. In order to provide appropriate support to eligible entities to use tire-derived aggregate (TDA) as opposed to conventional construction materials and ensure that these projects are engineered properly, engineering/design cost will be based on the project category, as indicated on the table below.

    Engineering/Design Cost (and Testing Cost for VLP)

    Project Category Maximum Percentage*
    Lightweight Fill 50%
    Vibration Mitigation 35%
    Low Impact Development 15%
    Landfill Application 10%

    *Percentage of the combined total cost of TDA material, installation, and testing. For Very Large Project (VLP), engineering/design and testing cost are subject to a percentage of the combined total cost of TDA material and installation only.

    Please refer to the Request for Approval for more information.

  2. When will the Notice to Proceed be issued?

    We anticipate approving eligible applications in April 2016, and sending out Grant Agreements in May 2016. Once we have a “fully-executed” Grant Agreement (meaning all parties have signed the agreement), we will issue the Notice-to-Proceed (NTP). The sooner we get the Grant Agreement signed by your Signature Authority, the sooner you will receive a NTP.

Additional money may become available in spring 2016 as a result of the Reallocation of Tire Funds.
