Everything You Ever Wanted to Know About Potholes, But Were Afraid to Ask

Is it me, or are there a lot more potholes out there?  I did some investigation, and determined that it isn’t just me.  There are actually over 2.7 gazillion more potholes today on our streets then there were last year.

Age, weather, moisture, traffic, heavy trucks, and delayed maintenance cause roads to deteriorate. Roads like ours that were built over 50 or more years ago with less sophisticated construction materials are reaching a point of exponential deterioration. Patching potholes here and there just doesn’t cut it anymore.  The problem is not just with the asphalt surface, but with the substructure of the roads.

The crown of a street and the emulsifying agents, together, beautifully work at repelling water only until there is a compromise in the pavement. Potholes (chuckholes, chunkholes, kettles, and tire-eaters by their aliases) are all formed basically the same way--traffic wear, old age, heat, and sunlight cause cracks to form in the water-repelling surface of the street. Once there is a crack, water seeps into the pavement, and erodes the sub-surface layers, creating an air gap or pocket below the surface. Water collects in this pocket and in colder climates expands and contracts in freeze-thaw cycles. In our more temperate climate the sheer volume of ground saturating water that we get in a short amount of time from the winter rains washes out the lower layers of stone and dirt, which support the surface layer. Then a heavy truck drives over the subsurface pocket and Voila!...a pothole is born.  That’s why so many of them appear in the Winter months.  And if left unrepaired, by springtime they’ve grown much larger.

A trillion dollars have been spent since the Eisenhower administration to build roads and keep them in working condition.  But the real problem is the aging substructure of the roads compounded by the growing amount of travel upon them.

  • The country’s 240 million registered vehicles drive more than 2.9 trillion miles annually.
  • Nearly 24 million children ride 450,000 school buses 180 days per year.
  • A fire department responds in one or more vehicles to a fire alarm in the United States every 20 seconds.
  • Delivery vehicles in the United States carry 64 billion pounds of goods per day.

A recent report by the American Association of State Highway Transportation states that,  “…despite the recent downturn in travel in 2008, the number of miles driven on the nation’s roadways has increased 41 percent from 1990 to 2007. Large commercial truck traffic, which places significant stress on pavements, has increased 50 percent during the same time frame.” But many roads, particularly in metropolitan areas and population growth centers, are in poor condition.  So, how do San Francisco’s roads fare?  Take a guess.

The San Francisco and San Jose metropolitan areas were tied for second worst in the nation behind Los Angeles.  Even Boston, the land of a million potholes, which even has a notorious pothole with its own Facebook page (I kid you not), ranks far higher than we do. 61% of San Francisco’s roads are in poor condition, 22% are fair, 4% are mediocre, and only 13% are in good condition.

TRIP, a national travel research group, estimates that for the average driver, roads that are in poor condition add $335 annually to typical vehicle operating costs. In San Francisco, the high concentration of poor roads adds an average of $705 to the maintenance of each vehicle.

But, there is a silver lining that makes San Francisco amazing yet again, and it can ease your pain. If your vehicle is damaged from a pothole or other road hazard, you can make a claim to the City Attorney’s office and be reimbursed for your expenses. I’ve done this…it really works. You must note specifically where the predatory pothole or hazard is, and you must show evidence of the damage. A claim must be filed within 6 months of the incident.
