Annual Crack Seal Program: Crack seal is a hot-pour, petroleum-based pavement crack and joint sealant which is used in conjunction with slurry seal to prevent premature failures and aging. Crack sealing is done annually, usually from July through September.

Annual Slurry Seal Program: Slurry seal slows down the pavement aging process and significantly reduces vehicle road noise. Slurry sealing is done annually, usually from July to September.

Pavement Skin Patching: Surface patching of arterial and collector street pavements is done during the dry-weather months, usually from July through September. Areas to be patched are determined from a visual survey by street crews or from citizen reports. Everything that is identified in a year is done.

Pot Hole Repair: We receive notice of a pot hole primarily through reports from citizens. These have a high priority and a temporary repair is done within 48 hours of notice. The site is then put on a list for a more permanent repair. Depending on the cause of the pot hole, the repair could require that the street base be rebuilt before the surface is replaced with new asphalt.

Concrete Street Repairs: The need to repair or replace a concrete street panel is identified through field observation (cracked or sunken panels) or as scheduled by the City's Pavement Management System. In this activity, the street panel is dug up and the base or subbase (soil) replaced, depending on the cause of the failure. Then a new concrete surface is laid. This type of work can be performed year-round.

Gravel Street and Alley Maintenance: There is less than a mile of gravel streets within the city limits. Of the 6.8 miles of alleyways, 2.4 miles are gravel and receive the same maintenance as the gravel streets. Gravel streets and alleys are graded and rock added as needed.

Bike Path Maintenance: Bike paths are off-street, paved surfaces that are used by bicyclists or pedestrians. These differ from bike lanes, which are designated areas on streets. Bike paths are swept 4 times a year. Areas needing maintenance are identified from visual inspections by the street crews or from citizen reports.

Pavement Management System: The pavement management system is software that records street inventory and condition information, analyzes the data, and predicts which streets are in need of various levels of maintenance. A condition assessment is conducted every 2-3 years to update the previous data and add new streets to the system. A contractor performs the condition assessment by a visual inspection.

Bridge Maintenance: A bridge inventory and maintenance history is stored in the City's Geographical Information System (GIS). Every other year, bridges are inspected by ODOT and rated on their structural sufficiency. If the bridge fails to receive an appropriate sufficiency rating, it is scheduled for replacement. Replacements are done by a contractor through the Capital Improvement Program. Routine maintenance is scheduled annually.

Utility Patching: After water and/or collection crews have made repairs to their facilities in the public rights of way, the street crews are responsible to asphalt or concrete the street, sidewalk or curb to as good or better condition than existed. Utility patching of streets is completed all year long.
