In those cases when a county desires to combine a RATA funded project with one or more non-RATA funded projects, the county, prior to advertising for the construction contract, or prior to commencing construction should any of the projects be scheduled for completion by county forces, shall notify the county road administration board in writing of its plans to combine the projects into a single construction project, assuring in writing that the work items assigned to the RATA funded section will remain distinct and separate through the bid documents and contract plans.

Upon verification that the request is submitted in a timely manner, that the combined project will meet the conditions of the CRAB/county contract and prospectus requirements, and that RATA funded items of work will be sufficiently separated from other work, the CRAB director will respond in writing, to grant the combination.
