Carson City’s local roads need some attention – and more funding – according to a report by the city’s transportation division.
“Without additional funding, particularly for local/neighborhood roads, the pavement condition will continue to get worse,” reads the report, which was submitted to the Regional Transportation Commission on Sept. 14.
Recent data, compiled by PAVER software, shows the pavement condition of local roads decreasing by 9 percent over the last five years, dropping from an index value of 61 to 56. For context, values of 50-69 are in the range of “at risk,” in need of minor resurfacing. But roads that fall below the threshold of 50 are considered to be in poor condition, needing major resurfacing. Below 25 are “very poor” roads that necessitate reconstruction. Values of 70 to 100 range from good to excellent condition.

 “It is important to note that the Pavement Condition Index values are beginning to decline at a faster rate,” the report states. “This is because the bulk of the city’s roads are approaching the performance curve that has the sharpest decline.”
In contrast, pavement condition of regional roads has improved by 10 percent, from 67 to 74.
“Regional road PCI has improved as a result of the RTC’s efforts and one-time federal transportation grant projects,” the report states.
The report also shows that in the last five fiscal years, $8.7 million in matching funds from local funding has been used to secure nearly $42 million in federal and state grants. But there’s a downside to federal money.
“Federal funding and grants are only eligible to be spent on regional roads (arterials and collectors),” Transportation Director Chris Martinovich said in an email. “Local/neighborhood roads are not eligible for federal money.”
According to the city, arterial roadways serve geographic areas that are “smaller than their higher classified roadways” and connect to larger roads. Collectors gather traffic from local roads and “funnel” to the larger network. Local roads, in contrast, are not intended for long-distance travel but still make up the largest percentage of city roadways.

Martinovich said the Board of the Supervisors has directed staff to narrow the number of potential funding mechanisms for local roads.
“We are currently focusing on four mechanisms, two related to sales tax and two related to some form of special assessment or neighborhood improvement district, but these are subject to change,” he said. “Those options, along with additional detail about the current pavement condition, will be provided during a future RTC meeting in either October or November. We are also working on a project website to roll out in the next couple weeks that details more of this information.”
The RTC meets the second Wednesday of every month after the Carson Area Metropolitan Planning Organization meeting in the Carson City Community Center.
