Spring Operations

Once the winter weather ends, Concord General Services’ Highway and Utilities Division begins spring operations for the City of Concord. Fluctuating temperatures from winter to spring can cause roads to shift. Roads easily shift during the spring thaw, which occurs when any frozen ice underneath the asphalt begins to melt. The spring thaw can cause potholes, sink holes, cracks, and road damage. Crews work in the spring to prevent and repair any road damages created during the spring thaw.

Use our request tracker to report any of the following concerns:
  •  Potholes
  •  Sink Hole
  •  Road Damage
  •  Blocked Catch Basin / Culvert
  •  Road Mark Fading
  •  Paving Concern
  •  Barricade Request
  •  Other


Hydrant Flushing

Concord Hydrant Flushing

Each spring, Concord General Services' Highway and Utilities Division flushes City-owned hydrants as part of required routine maintenance to remove any sediment from water distribution pipes. This process maintains water quality, water clarity, and also checks for water pressure. Water customers may experience low water pressure and discolored water in their area during hydrant flushing. Residents should avoid doing laundry during their scheduled flushing time. If discoloration occurs, please run your tap water on cold until the water runs clear. 

2018 Hydrant Flushing
Hydrant flushing for the season has been rescheduled to begin from Monday, April 16, 2018 to Monday, April 23, 2018 due to weather conditions. Areas scheduled are still the same, just delayed by one week. Flushing will continue for several weeks in different areas of the city. Concord water customers should check back here to find more hydrant flushing schedules published each week to determine when flushing will occur in their area.

Road Load Limit Postings

Spring Road Load Limits Lifted

Road weight restrictions in Concord have been lifted as of April 12, 2018. The City of Concord posted "No Trucking - Load Limit 9 Tons" signs on February 26, 2018, as warmer temperatures started the spring thaw. The spring thaw refers to when the temperatures fluctuate and the roads begin to melt any ice frozen underneath the asphalt, typically in areas indicating frost heaves and recent potholes. Road damage naturally occurs this time of year from the frequent thawing and freezing cycles, but heavy weight on weakened roads can cause additional harm. The amount of road damage is directly linked to how often a road is used and the weight of each load, especially if the road does not have a solid foundation. The City of Concord posted load limits set to 9 tons to protect streets from any potential damage from heavy vehicles. Road postings are no longer in affect for the season.

Road Damage and Potholes

Concord Potholes Cracked Road

Potholes are filled year round, but often during late winter and early spring as road structures are weakened from changing temperatures. Freezing and thawing cycles cause the ground to shift, which can then cause cracks in the pavement. Moisture from snow and rain then get underneath the roads through the cracks. The water remains underneath the roads left to freeze since the frozen soil prevents the water from draining. As the water underneath the road freezes, the road expands upwards creating frost heaves. As temperatures warm, the ground thaws and roads contract back down and potholes are formed. Crews repair potholes by first cleaning out the debris in the hole, filling it in with either cold patch or hot mix, and then using a compactor to compress materials.
