An agreement must be executed by and between TxDOT and the applicable Metropolitan Planning Organization (MPO) or LG on all projects. This will customarily be executed early on in project development, prior to a project receiving full authority to proceed for ROW acquisition and utility adjustments. The agreement will give details about the project and will state who is responsible for the ROW acquisition and the utility adjustments. If TxDOT is to be the acquiring agent, the fixed price participation amount required by the LG and the method of payment by the LG, either in full with the execution of the agreement or in periodic payments as approved by the Executive Director, will be detailed in the agreement.
