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.

Hydrant Flushing

Hydrant Flush

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.

2019 Hydrant Flushing

Hydrant flushing started on Monday, April 15, 2019. Flushing will continue for several weeks in different areas of the city. Concord water customers should view the tentative flushing schedules below to determine when flushing is scheduled to occur in their area. Please return to this page when your scheduled flushing time approaches to confirm there weren't any scheduling changes. Customers should remember to avoid doing laundry during their flushing time and to run their tap on cold to flush the lines if discoloration occurs.

*Please return to this page for any possible hydrant flushing changes.

Road Load Limits Lifted

Road Load Limits Lifted

Road load limits have been lifted as of April 22, 2019 due to the warmer weather conditions. All snow had to be completely melted and all ditches had to be dried up of any standing water before weight restrictions could be lifted. The City of Concord posted "No Trucking - Load Limit 9 Tons" signs on Monday, March 25, 2019 to protect roads from potential damage from heavy vehicles during 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. Roads are no longer posted for load limits and heavy vehicles may resume travel. We thank the community for their cooperation.

Potholes & Road Damage

Filled Pot Hole Picture

Potholes are filled year round, but are fixed more 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. Please use the request tracker above if you would like to report a pothole.
