Maintenance of Roadway, Sidewalks and Flood Channels

Routine maintenance of roadways is essential, efficient and cost-effective to sustain streets in good condition. The following high-quality maintenance programs are aimed at extending pavement life and improving levels of road serviceability.

  • Crack sealing is the application of a liquid asphalt/rubber compound injected into cracks and voids in existing pavement. Pavement life is extended by preventing water and other extreme elements from entering and deteriorating pavement surfaces. 
  • Pothole Patching is a process routinely used to repair minor irregularities in pavement surfaces. These irregularities can cause hazardous conditions and, in most instances, require immediate attention.
  • Gravel Roadways are maintained on more than 500 miles of native soil and gravel roadways in Clark County. The majority of these roadways is located in the rural areas of the county and primarily provides residential access. Gravel roadway grading usually occurs when the surface is eroded to the point where a hazardous or unsafe condition may eventually result.
  • Street Sweeping is a vital public service that not only improves the appearance of neighborhoods, but also helps prevent air pollution removing street dust that can be circulated by traffic. In the street sweeping process, storm drain inlets are also cleaned. Sweepers cycle through each respective central valley route approximately once a month.  Each sweeper picks up six to eight cubic yards of debris on a regular daily route. That amounts to capturing approximately 20,000 cubic yards of debris a year. As the seasons change from fall to winter, the average volume generally increases four-fold due to foliage droppings into curbs and gutters.
  • Snow and Ice Maintenance is necessary in the upper elevations of Clark County in areas such as Mt. Charleston, Kyle Canyon, Columbia Pass, Mountain Springs, and Cold Creek. Snow removal is accomplished using typical road maintenance equipment and two truck plows. In addition, we utilize two rotary snow blowers when snow depth exceeds our capacity to plow, which allows us to provide service with considerably greater efficiency.

In addition to the efforts of in-house staff, Public Works contracts with outside firms for both routine and specialized pavement maintenance activities. These projects maximize the value of the County's roadway assets by: extending useful life, remediating badly deteriorated roadway sections and by bringing County roadways into compliance with the Americans with Disabilities Act (ADA). Over the past seven years, more than $60 million in local gas tax monies have been directed toward this effort.

  • Slurry seals are mixtures of fine-graded sand and aggregates with quick setting asphalt emulsions. These are typically used on pavements that are 5 to 15 years old to extend the life of pavement by sealing out water and shielding the asphalt from oxidation due to ultraviolet rays.  
  • Pulverize and pave projects involve grinding up the existing asphalt on older, more deteriorated streets and recycling it as a high-quality base for an new layer of asphalt paving.
  • ADA compliance provides wheelchair ramps at intersections or the replacement of non-conforming intersection wheelchair ramps which do not meet applicable standards.
  • Flood Control Maintenance crew's activities are supplemented each year by an annual maintenance contract. The contractor provides equipment and personnel to complete a myriad of activities associated with the Flood Control infrastructure. This includes but is not limited to, inspections, channel debris removal, concrete repair, fence repair and replacement, box culvert cleaning, and detention basin maintenance. Annually, this contract costs approximately $1 million.
