Final cost distribution will be made on completion of the project. There shall be strict accountability of all funds and a report of all receipts and disbursements. 5. UTILITY RELOCATION COUNTY shall arrange for the relocation of all conflicting utilities within the project limits. DISTRICT shall pay only those relocation costs associated with utility relocation outside the road right-of-way. 6.
