Ditch & Berm Maintenance/Asphalt Patching Program

Roadside Ditch Maintenance

Roadside ditches are inspected and cleaned simultaneously as part of our storm sewer inspection and cleaning program. Typically, sections of ditchline that have silted in over the years will be re-graded upon request of the property owner and/or the Engineering Department. Private storm sewer pipe and driveway culverts encountered on unimproved streets will not be inspected, cleaned, or maintained by City personnel.

  • The entire ditch is not usually cleaned — only the portion where water flow is obstructed.
  • Ditches also serve as temporary retention areas. This allows additional time for the water drainage systems to carry excess water during heavy rains.
  • Over the years, some property owners have filled in their portion of a ditch, landscaping over top. This action is advised against, as it often causes drainage issues.

Berm Maintenance

Road edge berming of unimproved streets (no curb or gutter) is performed where deemed necessary to protect the road edge. Residential streets are bermed a maximum of 18 inches from edge of pavement.

Berming is done for the following reasons:

  • To support the asphalt edge of the street and prevent deterioration.
  • To provide a smooth transition from the road edge to the existing grade of the landscape
  • To prevent storm water runoff from ponding and freezing.
  • To allow handicapped accessibility.

Asphalt Maintenance – Spot Patching

The purpose of spot patching is to temporarily repair City streets until the entire street is resurfaced or reconstructed by the Engineering Department.

During the warmer months we use “hotmix” asphalt purchased from local asphalt plants. However, asphalt plants close during colder months and we must then 
use “cold patch” compound. Cold patch is not as long-lasting as hot mix and is used as a short-term solution until a permanent repair can be made. Spot patch crews check thoroughfares and residential streets on a regular basis. If you see a pothole, please report it to the City and crews will follow up as soon as possible.

Report a Pothole

Asphalt Maintenance – Major Patching

The purpose of major patching is to permanently repair larger areas of damage in streets. Major patching examples:

  • Areas where potholes are clustered.
  • Sinking water main breaks.
  • Utility access cuts in street.
  • Areas of a street that have weakened.
