The ditch was silting in therefore not draining properly, requiring regular cleanings.
Installed geotextile and rock with our specialized equipment from the berm and through the moat. Notice that one year later there is no silt in this ditch! The result is that this ditch will not need to be cleaned out for multiple years. Most plant ditches need regraded regularly and this is often delayed due to budget restraints at the time of building.
