Projects selected for funding are required to spend funds according to the approved project scope and budget. Timely progress reports are required for all projects. Project status will be updated at least bi-annually on the Bonds Accountability Website. Site visits may also be conducted during construction for development projects. Payment requests must include a certification by the project proponent that each expense complies with requirements outlined in the project agreement. Project proponents must also submit supporting documentation for each expense, with reimbursements approved only for eligible expenses pursuant to program guidelines and contained within the approved project budget. Programs may also withhold a portion of each payment request to be released contingent upon project completion.
