The Board of Supervisors Tuesday signed off on the final budget for a signage project along the Santa Ana River Trail, covering most points on the segment that traverses Riverside County with guideposts, relying on a federal allocation to pay for it. … The initial project budget was $1 million, but Regional Parks & Open Space District officials determined the full amount would not be required, so the board revised the final budget at a slightly lower sum in accordance with updated figures. “The signage program project aims to enhance the quality of life for Riverside County residents and Santa Ana River Trail users by maintaining clean, safe and equitable outdoor recreational opportunities,” according to documents posted to the board agenda.
