Driveway culverts should be inspected at least once a year. Maintenance work should be scheduled throughout the spring, summer and fall. Poorly working culverts can cause flooding during heavy rains and significant damage to roads. Even during normal wet weather, a crushed or plugged culvert that allows water to back up in the roadside ditches will contribute to the deterioration of the road as the standing water prevents further drainage from the road base.
ROUTINE SEASONAL CULVERT MAINTENANCE
- Inspect the inside as well as both ends of the pipe
- Remove obvious blockage (trash, brush, etc.)
- Remove blockages
- Clean and flush the length of the pipe. Remove inlet & outlet
- Repair, improve or install headwalls, pipe ends
- Trim and remove brush at pipe ends and mow grass and weeds
- Cut and remove trees and limbs that threaten to fall and block upstream ditches
- Establish vegetation on bare slopes at ends to prevent erosion
- Inspect the inside as well as the ends of the pipe
- Remove blockages (leaves, sticks, trash, etc.)
- Mark headwalls or pipe ends for snowplow operators
- DO NOT BLOW LEAVES INTO ROADSIDE DITCHES
Remember, inspecting and maintaining driveway culverts is the property owner’s responsibility.
