Ditching is cost-effective
  • Ditching is a preventative measure to future road repair. This can save tens of thousands of dollars every five years per road.
  • Proper ditching can prolong the life of a road.
Example: To ditch Chadbourne Ridge Road for 300 ft. will cost $2,904.00.
The repair of Chadbourne Ridge Road is expected to cost $60,295.00.
On average, the $2,904.00 investment will save the Town of Waterboro $60,000.00 to $120,000.00 in ten to fifteen years.
