Renovation work has begun at Riverfront Park. A crew moved in Monday to begin making improvements to the area and will be working there over the next five weeks.Temporary closures are possible with the boat ramp being closed Tuesday.“It’s going to look nice once they’re done,” said McMinnville Parks and Recreation director Scott McCord. “I think the entire process will take about five weeks.”Work will include bank stabilization along the river, replacing two docks, dock dredging cleanup, replacing the concrete boat ramp, and applying gravel to the parking area.
