Pavement Management Program

If you come across any areas during your travels through Longmont which need attention or repair, please let us know by making a report through ServiceWorks!. If a pothole is so large or deep that it is presenting a safety hazard for motorists or pedestrians and it is a weekend, please call and report it to Longmont Public Safety Dispatch.

To better serve the traveling public, the City of Longmont has street improvement programs included in its capital improvement plan. Improvements are scheduled on an annual basis according to need and available resources. Street improvements include resurfacing, widening and other major improvements which are not categorized under normal street maintenance programs. In addition, sidewalk repair and replacement is included in these efforts. Information can be obtained on streets currently scheduled for improvements by visiting our Road and Bridge Construction webpage as well as our Paving and Concrete webpage, which identifies projects selected as part of the Pavement Management Program.

You can see a list of projects on the Pavement Management Program webpage or by contacting Transportation. If your street has been selected for treatment, you will receive a project notification letter in the mail. Construction typically begins in the spring or summer. As construction approaches, a door hanger will be posted on your home to inform you more specifically of the upcoming activities.

When you submit your request to ServiceWorks!, a member of our customer service team will receive that request and immediately send it to our Street Operations team. At that point, our Street Operations team will regularly review the pothole and other street maintenance requests that come in. They will visit the site requested and complete their own evaluation of the pothole or street maintenance. If the Street Operations team determines that the pothole needs to be fixed, they will add it to their list of work to be completed. Depending on workload, time of year and other factors, the maintenance work could be completed within days or weeks. Street repairs are different because all streets that will be fixed in the current calendar year have already been identified and submitted to the Pavement Management Program to be included in that year’s street operations and engineering budget. Streets that need improvements will be evaluated and, if deemed necessary, will be added to the Pavement Management Program for the following calendar year.

The number of potholes fixed changes every year based on the requests received by residents, evaluations from staff and road and weather conditions throughout Longmont. However, in 2023, the City of Longmont’s Street Operations team patched 6,004 potholes throughout the City.

The number of streets varies from year to year based on the length of the portion of the street being rehabilitated, the normal traffic patterns on the streets and other factors. For 2024, 26 streets were identified for asphalt and concrete rehabilitation. Those can be found on the street rehabilitation letter found on the website. In addition, 32 more streets were identified for chip seal maintenance in 2024, and those can be found on the citywide chip seal letter.

Chip sealing is a preventive maintenance treatment that consists of the application of crushed aggregate or gravel (chips) over an emulsified asphaltic oil. A chip seal is applied to streets that are in relatively good condition but have begun to deteriorate. Chip sealing is a cost effective method used to prolong the useful life of the street and delay more expensive types of rehabilitation. In complement to the chip seal, a similar treatment known as slurry seal will be used at the end of all cul-de-sacs.

Crack sealing is the process of placing an adhesive sealant into cracks on the pavement surface, preventing the infiltration of moisture and non-compressible materials into the pavement. It is a cost-effective pavement preservation treatment that can slow pavement’s deterioration and extend pavement life by at least 3-5 years.

Concrete rehabilitation includes the removal and replacement of concrete on curbs, gutters, sidewalks and other associated concrete, and is completed before asphalt work. Existing cobblestone or gravel will be re-set following construction and any impacted irrigation pipes or sprinkler heads will be relocated, if needed. Asphalt reconstruction includes an overlay of a new layer of asphalt placed on top of the existing street surface that is in relatively functional condition. Preparatory tasks include asphalt patching, edge milling and utility adjustments that will be completed prior to the overlay. There is likely going to be periods of inactivity between the two types of rehabilitation. It is the City’s goal to efficiently and effectively complete this important work throughout the city.
